  SPEAKER_02: Welcome to Planet Geo, the podcast where we talk about our amazing planet, how it works, and why it matters to you.
• 0:13
  SPEAKER_00: Hi, Chris.
• 0:14
  SPEAKER_00: Hey, how you doing there?
• 0:16
  SPEAKER_00: Hey.
• 0:16
  SPEAKER_00: Dr.
• 0:17
  SPEAKER_00: Man Bun there.
• 0:18
  SPEAKER_00: You you got it all slicked back for me today.
• 0:21
  SPEAKER_00: You know what?
• 0:22
  SPEAKER_00: I do.
• 0:22
  SPEAKER_00: You have a headache?
• 0:23
  SPEAKER_02: You gotta pull tight.
• 0:25
  SPEAKER_02: I did earlier today, actually, but it was not because my bun was too tight.
• 0:29
  SPEAKER_00: Why not?
• 0:30
  SPEAKER_00: Like, I don't know.
• 0:31
  SPEAKER_00: What do you have a headache for then?
• 0:32
  SPEAKER_00: Are you stressed just?
• 0:33
  SPEAKER_02: It's been a week.
• 0:34
  SPEAKER_02: I'm a little bit.
• 0:34
  SPEAKER_02: I'm a little bit a little bit.
• 0:36
  SPEAKER_02: It's busy.
• 0:37
  SPEAKER_02: There's grant deadlines due.
• 0:39
  SPEAKER_02: There's papers that got rejected that need to be resubmitted.
• 0:42
  SPEAKER_02: You know, it's kind of an end of fiscal year deadline stuff going on right now.
• 0:46
  SPEAKER_02: But you, Chris, are wearing a different shirt than the one that you've recorded the last like four episodes in.
• 0:52
  SPEAKER_02: You usually have your blue flannel hoodie on and you have a North Face jacket.
• 0:57
  SPEAKER_00: I do.
• 0:57
  SPEAKER_00: Same theme, but different actual like same theme.
• 1:01
  SPEAKER_00: No, actually, no, the theme is way different.
• 1:03
  SPEAKER_00: That hoodie that I usually wear, that thing is a piece of crap.
• 1:06
  SPEAKER_00: It has a big tear in it.
• 1:08
  SPEAKER_00: I've seen.
• 1:09
  SPEAKER_02: I am trying not to be offended that you always wear it to record podcasts with me.
• 1:14
  SPEAKER_00: I don't know.
• 1:15
  SPEAKER_00: It's just comforting to wear.
• 1:17
  SPEAKER_00: I like it.
• 1:18
  SPEAKER_00: Okay.
• 1:18
  SPEAKER_02: Fair enough.
• 1:20
  SPEAKER_02: Fair enough.
• 1:21
  SPEAKER_02: Office hours.
• 1:22
  SPEAKER_02: We have, as usual, some great questions from you, the listener.
• 1:26
  SPEAKER_02: Thank you for sending them in.
• 1:27
  SPEAKER_02: Keep it up.
• 1:28
  SPEAKER_02: These are really interesting.
• 1:29
  SPEAKER_02: And it's actually kind of thought-provoking.
• 1:31
  SPEAKER_02: I think the today's one is in particular a thought-provoking.
• 1:35
  SPEAKER_02: Well, we have two.
• 1:36
  SPEAKER_02: That's true.
• 1:36
  SPEAKER_02: Good point.
• 1:37
  SPEAKER_02: What are we doing?
• 1:38
  SPEAKER_00: We got a question about careers in geoscience and what our advice is to whether they should go back and pursue this kind of passion that they have.
• 1:47
  SPEAKER_00: So that's that's the first one.
• 1:49
  SPEAKER_00: And the other question dealt with mass spectrometers and new advances and yeah, updates and techniques.
• 1:57
  SPEAKER_02: Yeah, that's right.
• 1:57
  SPEAKER_02: Uh the first one, I mean, I think we should, Chris, if you think so, we should cover the first one first because uh that's like a meaty discussion, I think.
• 2:04
  SPEAKER_02: And there are several people who have emailed us kind of in the same theme of career advice.
• 2:11
  SPEAKER_02: Like a lot of them are kind of do I go back to college for geology or not, or good, do I go to graduate school for geology or not?
• 2:19
  SPEAKER_02: Basically, kind of in the theme of as you said it, do I pursue this passion academically or not?
• 2:25
  SPEAKER_02: And I'd be really curious to hear your thoughts on this, Chris.
• 2:28
  SPEAKER_02: I find it hard to give really personal advice on this front.
• 2:34
  SPEAKER_02: Like it's such a deeply personal question.
• 2:37
  SPEAKER_02: We can weigh in in general, uh, is the way I feel.
• 2:40
  SPEAKER_02: But what do you think?
• 2:40
  SPEAKER_02: I mean, what are your thoughts when when people are you know struggling with this?
• 2:44
  SPEAKER_02: Because I think you did when you were, you know, going through the process of your education.
• 2:49
  SPEAKER_00: I definitely did.
• 2:50
  SPEAKER_00: It's really interesting that you say what you just said because my take on that question is yeah, I have something to say to that.
• 2:57
  SPEAKER_00: And it maybe it's because it is so personal to me because I did go through this very kind of crisis, I guess, if you will.
• 3:04
  SPEAKER_02: Yeah.
• 3:05
  SPEAKER_02: Um so what was that in your personal life, maybe first?
• 3:08
  SPEAKER_02: Or how did you experience this?
• 3:10
  SPEAKER_00: I had no idea what direction I was gonna go.
• 3:13
  SPEAKER_00: I just knew I was gonna go to college, but I didn't know why.
• 3:17
  SPEAKER_00: You know, so I did go right out of high school, and I I don't know, I spent the first year and a half in my college career just taking general ed classes and and then really starting to sweat because nothing grabbed me.
• 3:28
  SPEAKER_00: I didn't know what I was gonna do.
• 3:29
  SPEAKER_00: And my dad always, my dad had always said, Hey Chris, you're gonna you're gonna know it's just gonna land in your lap, and and when it's there, you'll just but I was running out of faith.
• 3:38
  SPEAKER_00: You know, something better grab me sooner.
• 3:40
  SPEAKER_00: I'm just gonna end up going in a direction for no particular reason.
• 3:44
  SPEAKER_00: And that's really almost what happened.
• 3:46
  SPEAKER_00: I mean, shoot, Jesse, I was I was taking business classes.
• 3:50
  SPEAKER_00: That was my major right before geology.
• 3:52
  SPEAKER_00: That was business.
• 3:53
  SPEAKER_02: That would have been an unhappy Chris Belhois as a business major.
• 3:58
  SPEAKER_00: No, I I shudder to think about this.
• 4:01
  SPEAKER_00: So when I found geology, and you know, I've told this story, so I'm not gonna retell it, but I knew that this was it, right?
• 4:10
  SPEAKER_00: This was something that I was excited about.
• 4:13
  SPEAKER_00: And really, that's the first time that that had happened.
• 4:16
  SPEAKER_00: And I knew this was it.
• 4:18
  SPEAKER_00: And so I didn't know my trajectory though at that point.
• 4:21
  SPEAKER_00: I didn't know what path I was gonna take.
• 4:22
  SPEAKER_00: I just knew that it was gonna deal something with geology.
• 4:25
  SPEAKER_00: It had to be.
• 4:26
  SPEAKER_02: And you were what, a junior in college when this happened?
• 4:29
  SPEAKER_02: A software, maybe.
• 4:31
  SPEAKER_02: A sophomore, yeah.
• 4:32
  SPEAKER_02: Sophomore, yeah.
• 4:33
  SPEAKER_02: And then so you graduated with an earth science degree, right?
• 4:36
  SPEAKER_02: If I remember correctly, no geology degree.
• 4:39
  SPEAKER_00: No, I graduated with a degree in geology, and then I got married right away after after I graduated in Jenny, and I moved out to Oregon for a year, and then just for personal reasons and so on, we wanted to move back.
• 4:51
  SPEAKER_00: Jenny really she's got a close connection with home and she wanted to be closer to home.
• 4:55
  SPEAKER_00: So we moved back, and that's when I had to decide, all right, what am I gonna do now?
• 5:00
  SPEAKER_00: I needed to change my trajectory because at the time I didn't really want to do environmental geology, and and again, I I would rethink that now.
• 5:09
  SPEAKER_00: I think it's a very exciting field now, and I would look really hard at going in that direction, but at the time that wasn't my thing, and so I did have to change directions, and it was not an easy path.
• 5:22
  SPEAKER_00: I had to go back to school for two more years, and I had to do my student teaching just so I could chase my passion, which was to still be heavily involved in the field of geoscience.
• 5:35
  SPEAKER_00: Just now I want to teach it.
• 5:36
  SPEAKER_02: So you went back to get the teaching degree is what you kind of went back for.
• 5:40
  SPEAKER_02: Okay, gotcha.
• 5:41
  SPEAKER_00: Yeah, and I think and that worked out great, Jesse, for me, because I had to do all the hard stuff.
• 5:47
  SPEAKER_00: I had to go to field camp, I took structure, I took sed strat, calculus, all this stuff, right?
• 5:52
  SPEAKER_00: Whereas if I had just gone into teaching and I just went the earth science route right away, I wouldn't have those experiences.
• 6:00
  SPEAKER_00: And I think those experiences provided me with the confidence to do what I do in my geology class, you know, make this uh geology field course that's three weeks long.
• 6:10
  SPEAKER_00: I that whole experience in Grand Valley just provided me with the confidence to go ahead and plow forward with it.
• 6:19
  SPEAKER_02: Okay.
• 6:20
  SPEAKER_02: A comment and then two questions.
• 6:22
  SPEAKER_02: The comment is first of all, I think you got your undergrad degree before oil had been discovered, probably.
• 6:27
  SPEAKER_02: So, like it was really there was no career opportunities in the geoscience field apart from teaching.
• 6:32
  SPEAKER_02: No, I'm kidding.
• 6:33
  SPEAKER_02: But have you the question is really have you have you looked back or or have there been second guesses or what led you to go into teaching with the geology after getting a geology degree, as opposed to I guess the environmental side?
• 6:48
  SPEAKER_02: You know, can you can you kind of tease apart that decision or that decision process?
• 6:51
  SPEAKER_00: Are you asking if I regret not going the environmental?
• 6:55
  SPEAKER_00: No, not regrets.
• 6:55
  SPEAKER_02: I know you you're like, you know, you're you don't have regrets, right?
• 6:59
  SPEAKER_02: And so I you make a decision and then you don't really look the other direction.
• 7:02
  SPEAKER_02: You don't look down the old path that you could have taken, really.
• 7:05
  SPEAKER_02: And so that's not really my question.
• 7:07
  SPEAKER_02: My question is can you kind of tease apart that decision you made between environmental or geoscience industry or being a like more of a practicing geologist out there versus the teaching route?
• 7:16
  SPEAKER_02: That fork in the road, you know, what did that decision look like for you?
• 7:20
  SPEAKER_00: Yeah, I remember having this discussion with Jenny.
• 7:22
  SPEAKER_00: It was a tough thing because she was teaching elementary, she'd got a job right when we moved back.
• 7:27
  SPEAKER_00: And so for me to not be working and go to go back to school full time and pay tuition, so not only am I not working, I'm also paying college tuition.
• 7:39
  SPEAKER_00: And I'm married, you know, I'm not living with mom and dad anymore, or you know, I don't have any support that way.
• 7:44
  SPEAKER_00: That was tough.
• 7:45
  SPEAKER_00: I mean, we were poor.
• 7:47
  SPEAKER_00: And I don't regret that at all, but we were absolutely poor.
• 7:52
  SPEAKER_00: So what led me to the decision is you know, I I had to take a bunch of classes that I didn't want to take to go the teaching route, but I had decided that I wanted to do that.
• 8:04
  SPEAKER_00: I wanted to be a teacher and I didn't want to work in the environmental field, but I didn't want to take these classes either.
• 8:10
  SPEAKER_00: And you know, you know exactly how Jenny is.
• 8:12
  SPEAKER_00: She's she looked at me and she's like, Well, is this the path you want to go?
• 8:16
  SPEAKER_00: And I said, Yeah.
• 8:17
  SPEAKER_00: And she said, Well, suck it up and do what you have to do then.
• 8:20
  SPEAKER_01: And quit being a baby.
• 8:21
  SPEAKER_01: Like, what are you complaining about?
• 8:23
  SPEAKER_01: Go do it.
• 8:24
  SPEAKER_01: Yeah.
• 8:24
  SPEAKER_00: Right.
• 8:25
  SPEAKER_00: And and so that's what I did.
• 8:26
  SPEAKER_00: Yeah, I really did not want to take some of the classes.
• 8:29
  SPEAKER_00: And to be quite honest with you, it was it was a bunch of chemistry that I had to take yet, and um, that just didn't do it for me, you know.
• 8:36
  SPEAKER_00: And so that was the only thing that kind of held me back, other than the financial side of it.
• 8:42
  SPEAKER_00: I could have just gone on and gotten a job, you know, in the environmental side and and gone to work.
• 8:47
  SPEAKER_00: But looking back, I made the right call for sure.
• 8:49
  SPEAKER_02: So bringing that forward to like advice today to people who are, you know, maybe in that same position who are deciding maybe it's grad school they're thinking about, or maybe it's going back, maybe they got the business degree and are thinking about going back to get a geoscience degree.
• 9:02
  SPEAKER_02: I don't know.
• 9:02
  SPEAKER_02: I think I probably know what your advice is gonna be, but I'm not sure.
• 9:05
  SPEAKER_02: I want to what do you think?
• 9:06
  SPEAKER_02: What are your thoughts?
• 9:08
  SPEAKER_00: I think follow your passion.
• 9:10
  SPEAKER_00: That I mean, always.
• 9:11
  SPEAKER_00: I think that's always gonna be my advice because I'm passionate about my job.
• 9:16
  SPEAKER_00: I'm I'm passionate about what I teach, and I'm really grateful for it too.
• 9:22
  SPEAKER_00: Every day I try to remind myself of how lucky I am to be in my situation, then that's just because I I get to do something that I absolutely love, and I can't understate that.
• 9:31
  SPEAKER_00: I mean, I I think that passion in all facets of our life is just one of the most important things to have, and so you know the the bullheises are passionate people.
• 9:42
  SPEAKER_02: You you guys are uh you know, two to an individual, passionate in various in various things.
• 9:49
  SPEAKER_02: What I know about the bullheises is that they are passionate indeed.
• 9:53
  SPEAKER_02: That's true.
• 9:54
  SPEAKER_02: I was actually I was thinking to myself, yeah, I wonder what Chris will say, but in retrospect, I should have known that this is how you answer it, right?
• 10:01
  SPEAKER_02: There's no question.
• 10:02
  SPEAKER_00: Well, okay, what about you then?
• 10:04
  SPEAKER_00: Like, what's your take on it?
• 10:06
  SPEAKER_02: So I guess a little bit about my path.
• 10:08
  SPEAKER_02: I went to college knowing I wanted to do geology because I'd taken your class, and we've talked about this before, right?
• 10:13
  SPEAKER_02: Because of you, I knew I wanted to go do geology.
• 10:16
  SPEAKER_02: But that's not to say that there were not times along the path that I sort of second guessed what I was doing.
• 10:20
  SPEAKER_02: I do really distinctly remember having this discussion with a mentor of mine at the end of undergrad when I was deciding am I gonna go to grad school or not?
• 10:29
  SPEAKER_02: And I was sort of like, I said, I'm not sure if this geology thing is just a sort of a hobby that got too big in my life or not.
• 10:36
  SPEAKER_02: Because it kind of felt that way.
• 10:38
  SPEAKER_02: Like, okay, I like collecting rocks.
• 10:39
  SPEAKER_02: We talked about this in a recent episode.
• 10:40
  SPEAKER_02: Like, I like collecting rocks.
• 10:42
  SPEAKER_02: Did that get too big in my life?
• 10:43
  SPEAKER_02: Like, do I need to do a major in it?
• 10:45
  SPEAKER_02: What am I gonna do with this degree?
• 10:46
  SPEAKER_02: And I think this might be particular to Michigan or to the Midwest in the time that I was coming of age and the time that you did as well.
• 10:54
  SPEAKER_02: There was not a big geoscience industry in the region.
• 10:59
  SPEAKER_02: You know, is environmental consulting or teaching, and that's kind of the two decisions.
• 11:03
  SPEAKER_02: The ones you had were the kind of the same ones I had with an undergrad degree.
• 11:07
  SPEAKER_02: And then I went to Canada for graduate school and kind of the world blew up in front of me, meaning like the options were laid out that you can go be a minerals exploration geologist, you can be an oil and gas geologist, you can do a lot of different stuff with a geology degree, and I chose the academic route.
• 11:22
  SPEAKER_02: So I I guess all that to say that I don't feel that it was the only path to take, but I I did struggle with it, and it clearly was the right one.
• 11:29
  SPEAKER_02: But um, I struggled along the way with that decision.
• 11:32
  SPEAKER_02: Should I go to grad school or not?
• 11:34
  SPEAKER_00: Well, okay, well, then answer the question because you're kind of being roundabout with us, like should you know, we got a question.
• 11:40
  SPEAKER_00: It was pretty direct.
• 11:41
  SPEAKER_00: What do you think?
• 11:42
  SPEAKER_02: Should I go back?
• 11:43
  SPEAKER_02: I mean, I'm really hesitant to give advice on this.
• 11:46
  SPEAKER_02: Like it is a deeply personal thing.
• 11:47
  SPEAKER_02: Like you, you kind of laid out, you know, it's a relate, you have a relationship to consider, you have location to consider, like there's a lot of factors.
• 11:54
  SPEAKER_02: You have financial abilities to pay for college, like all that is a consideration here, right?
• 11:59
  SPEAKER_02: Now, what I will say is that the geoscience job market, I know for a fact, has changed a lot.
• 12:04
  SPEAKER_02: And there are so many new geoscience-related industries that are opening up.
• 12:09
  SPEAKER_02: I saw a chart recently of carbon technology companies, the fundraising of carbon technology companies, and they are raising billions of dollars, and they all need geochemists.
• 12:20
  SPEAKER_02: So, like a geochemistry degree is like newly valuable.
• 12:24
  SPEAKER_02: You used to be able to just go maybe look for gold or maybe look for oil, and now there's this whole wide world of employment sectors that kind of need geoscientists to go work for them.
• 12:35
  SPEAKER_02: And I don't really know what that'll look like in 10 years or five years when somebody finishes a degree.
• 12:39
  SPEAKER_02: So it's hard to say, oh, look, you can go do this job now.
• 12:42
  SPEAKER_02: That's a hard one because there's so much changing right now.
• 12:45
  SPEAKER_02: But I think the degree will be valuable in a way that it maybe wasn't for you and I.
• 12:49
  SPEAKER_02: So it I don't think it necessarily has to be just a passion decision, right?
• 12:53
  SPEAKER_00: I think you're right.
• 12:53
  SPEAKER_00: I mean, it's hard to go wrong if you're really in love with something.
• 12:58
  SPEAKER_00: It's hard to go wrong following that.
• 13:00
  SPEAKER_00: I agree.
• 13:01
  SPEAKER_00: It's hard to say, well, yeah, this is what you should do.
• 13:04
  SPEAKER_00: And so our disclaimer out there is this is just what we think.
• 13:08
  SPEAKER_02: You know, and totally everyone needs to do what's right for you, but yeah, uh two guys on a podcast.
• 13:14
  SPEAKER_02: But I I will say my advice also differs depending on what we're talking about.
• 13:18
  SPEAKER_02: Like an undergrad degree is kind of a bigger commitment in many ways.
• 13:23
  SPEAKER_02: If you don't have a geoscience degree and you're thinking about going to get an undergrad degree, that's a big time commitment, financial commitment.
• 13:28
  SPEAKER_02: A master's degree is in some ways kind of a lower commitment in a weird way.
• 13:33
  SPEAKER_02: Like if you have a geoscience undergrad and you're thinking about going and getting a master's degree, that's a two-year thing.
• 13:39
  SPEAKER_02: It gets paid for you, or at least you get some living stipend.
• 13:42
  SPEAKER_02: So you're not going more into debt to get the degree.
• 13:45
  SPEAKER_00: Well, let me interrupt you.
• 13:46
  SPEAKER_00: That depends on what kind of master's degree you get.
• 13:49
  SPEAKER_00: If you're getting a research master's degree, then you're gonna get funded.
• 13:54
  SPEAKER_00: But if you're taking classes, then you're gonna have to pay for that.
• 13:57
  SPEAKER_02: That's a good point.
• 13:58
  SPEAKER_02: There are new programs, like one-year master's programs that you'll pay for.
• 14:02
  SPEAKER_02: But I guess what we have in our department is the two-year thesis-based master's of science degree, which is funded for you.
• 14:08
  SPEAKER_02: You you at least don't go into more debt.
• 14:10
  SPEAKER_02: You know, you get a living stipend, which is small but allows you to live without going into more debt.
• 14:14
  SPEAKER_02: A PhD is a high-risk thing.
• 14:16
  SPEAKER_02: Like, you gotta know, in my opinion, before you go into a PhD, you gotta know what you want to do or like why you want the PhD.
• 14:22
  SPEAKER_02: Don't go into a PhD.
• 14:23
  SPEAKER_02: That's a four-year commitment.
• 14:25
  SPEAKER_02: You don't go into more debt, but you also don't make any money for four years.
• 14:30
  SPEAKER_01: You know, hey, I was five years, five, just over five years.
• 14:34
  SPEAKER_00: Well, and then you're postdoc.
• 14:36
  SPEAKER_00: We gotta throw that in there too.
• 14:38
  SPEAKER_02: But it you know, you don't make any money for a long time, which is uh which is a financial sacrifice in a way.
• 14:43
  SPEAKER_02: So I don't know.
• 14:44
  SPEAKER_00: Way too many beers for you.
• 14:46
  SPEAKER_00: I just felt bad.
• 14:46
  SPEAKER_00: We would get together, I'm like, okay, I'll buy again, Jesse.
• 14:49
  SPEAKER_00: You know, you have bigger.
• 14:50
  SPEAKER_00: And you're like, geez, this dude's like 26, like he can't buy his own beers.
• 14:54
  SPEAKER_02: What's going on here?
• 14:57
  SPEAKER_02: That's funny.
• 14:58
  SPEAKER_02: Yeah, but it's true.
• 14:59
  SPEAKER_02: It is a that is a it's a big commitment.
• 15:01
  SPEAKER_02: So I kind of feel like an undergrad is kind of more of a commitment than a master's, and then less than a PhD.
• 15:06
  SPEAKER_02: So I think my advice kind of depends on the degree you're sort of talking about.
• 15:11
  SPEAKER_00: Um and also to the direction that you're gonna go.
• 15:15
  SPEAKER_00: You know, there are some directions where a bachelor's degree or four-year degree is the it's the working degree, but there are other directions where master's is the working degree, and then of course, academia is gonna be a PhD.
• 15:25
  SPEAKER_00: So it depends upon that also, like what avenue you want to follow once you make your decision about all right, I'm gonna go into geology.
• 15:33
  SPEAKER_00: Well, there are so many different roads to take.
• 15:35
  SPEAKER_00: So there's that's really true, Chris.
• 15:37
  SPEAKER_02: And I just actually saw uh back to the employment thing.
• 15:41
  SPEAKER_02: I just saw a stat that the projections are by 2025 we will have a deficit of a hundred thousand geoscientists, i.e., we will need a hundred thousand more geoscientists out there in the working industry than we will have trained to do it.
• 15:55
  SPEAKER_02: So there's gonna be a demand for geoscience skill sets, and there's gonna be a demand for like blended skill sets.
• 16:00
  SPEAKER_02: Our fastest growing miner in our program is an earth science policy miner.
• 16:05
  SPEAKER_02: And this is a really popular um field to go into.
• 16:09
  SPEAKER_02: States are hiring geoscientists in that kind of policy, or maybe not geoscientists, earth scientists in that kind of policy and science communication sort of blended mode.
• 16:19
  SPEAKER_02: So that's a big opportunity for people to kind of scratch the itch of geoscience, but also scratch another itch for themselves with policy.
• 16:26
  SPEAKER_00: Think about this too: getting a a bachelor's degree in geology and then going on to get a law degree, something like that.
• 16:32
  SPEAKER_02: Oh my goodness.
• 16:32
  SPEAKER_02: Talk about marketable.
• 16:34
  SPEAKER_02: Man, there there's people in our program who get uh geoscience degrees as well as a double major in finance.
• 16:40
  SPEAKER_02: And oh my god, are you employable with that?
• 16:43
  SPEAKER_02: I think like especially with some geochemistry in there, that's a really, really powerful combination in the growing economy of geoscience, uh the future of geoscience employment, energy sectors turning over, all this stuff's happening.
• 16:57
  SPEAKER_02: That's super exciting.
• 16:58
  SPEAKER_00: So that's right.
• 17:00
  SPEAKER_00: And I think there are jobs that are going to be geology related in the next decade or so that we don't even know about yet at this point.
• 17:08
  SPEAKER_00: It's dramatically different than even when you came out, but it's dramatically different from when I came out.
• 17:15
  SPEAKER_00: I mean, it's just that it doesn't even look the same.
• 17:17
  SPEAKER_02: I think the sector when I came out of when I graduated college is very similar to the the sector when you graduated college.
• 17:23
  SPEAKER_02: Like you know, right?
• 17:25
  SPEAKER_02: We're like 15 years difference or something like that.
• 17:27
  SPEAKER_02: It's it was pretty much the same, but I think between my generation and the current generation, it is light years difference.
• 17:34
  SPEAKER_02: It's kind of crazy.
• 17:34
  SPEAKER_02: I mean, I'm teaching in this fall, I'm gonna teach an entrepreneurial geoscience class because there are just so many startups that are happening that are in the geoscience space of various like parts of the geoscience space that I think we kind of have to get a grasp on where this industry might be going because our undergrads they might go start companies in this space, and that would be really great for everybody.
• 17:56
  SPEAKER_02: So there's just loads of opportunity.
• 17:59
  SPEAKER_02: So maybe I'm giving advice to say go back.
• 18:02
  SPEAKER_02: Maybe I'm talking myself into saying you are.
• 18:04
  SPEAKER_02: You know, pursue the passion because it's also gonna be practical.
• 18:09
  SPEAKER_00: And mine is John, just go follow your dreams and follow your passion.
• 18:13
  SPEAKER_00: How you know, how can you go wrong?
• 18:14
  SPEAKER_00: You're gonna find your way.
• 18:15
  SPEAKER_00: That's right.
• 18:16
  SPEAKER_00: That's true.
• 18:16
  SPEAKER_00: That's true.
• 18:17
  SPEAKER_00: Uh I believe that, but it is personal, and so that you know, yeah, it could be tough, recognizing that it can be a tough decision at times for sure.
• 18:27
  SPEAKER_00: All right, we have another one, Jesse, about mass spectrometers and updates on like new techniques.
• 18:35
  SPEAKER_00: So this is right up your alley.
• 18:37
  SPEAKER_00: Um so why don't you give this one a whirl?
• 18:40
  SPEAKER_00: This is by Richard.
• 18:41
  SPEAKER_00: You know, talk a little bit about the technique and and is there new stuff on the horizon with mass spectrometry?
• 18:48
  SPEAKER_02: Oh man.
• 18:49
  SPEAKER_02: You know, I so I can't claim to know everything that every lab group is working on, but there's a lot of stuff always going on with mass spectrometer development.
• 18:56
  SPEAKER_02: Our lab, my lab, we've decreased in some aspects, in part because we can't get funding for the the projects, and there's more interesting stuff going on, I think.
• 19:06
  SPEAKER_02: So there's like projects kind of die without completing them necessarily or or going as deep as you want to go.
• 19:12
  SPEAKER_02: There's always stuff with mass spectrometers that are being developed.
• 19:14
  SPEAKER_02: The most recent and most impressive stuff I've seen recently is like the sort of micro mass spectrometers.
• 19:20
  SPEAKER_02: So things they're trying to put on spacecraft or things they are putting on spacecraft to go measure isotope ratios on Mars or on the asteroids that they're going to go visit.
• 19:30
  SPEAKER_00: Um that's crazy because I've seen yours and they're big.
• 19:33
  SPEAKER_00: They take up a whole room.
• 19:34
  SPEAKER_02: The ones I work on are big and you wouldn't be flying these into space.
• 19:38
  SPEAKER_00: No.
• 19:39
  SPEAKER_00: That's a good point.
• 19:40
  SPEAKER_00: Um that's crazy.
• 19:42
  SPEAKER_00: Okay.
• 19:43
  SPEAKER_00: Do you lose accuracy with these smaller ones?
• 19:46
  SPEAKER_02: Well, they lose precision, right?
• 19:48
  SPEAKER_02: So you you basically make larger, you make data points with larger uncertainties, but like if you're trying to get a measurement from Mars, we have very few measurements from Mars.
• 19:58
  SPEAKER_02: So any data is more valuable than no data, right?
• 20:01
  SPEAKER_02: So it kind of doesn't even matter how big the uncertainties are because the questions are so big.
• 20:06
  SPEAKER_02: We don't know like what is the atmospheric composition around Mars or Venus.
• 20:10
  SPEAKER_02: Like we don't really know that stuff.
• 20:11
  SPEAKER_02: So, or maybe we do hydrogen, but not oxygen, right?
• 20:14
  SPEAKER_00: We do, yeah.
• 20:14
  SPEAKER_00: We they they do because they they talk about on Mars like deuterated water versus non-deuterated water, and the ratio of deuterated water, which deuterated water is a reference to deuterium, which is H2.
• 20:26
  SPEAKER_00: It's got a neutron in the nucleus, and the vast majority of hydrogen is just H1 with one proton and no neutron.
• 20:33
  SPEAKER_00: So it's heavy hydrogen.
• 20:34
  SPEAKER_00: And based upon the ratio of that in Mars, they are able to then walk back how much water has been lost by Mars.
• 20:44
  SPEAKER_00: So how much water they think it had.
• 20:46
  SPEAKER_00: That's really, really cool science, if you ask me, because Mars doesn't weigh enough to hold on and retain that lighter hydrogen, but it does weigh enough to hold on to the deuterated hydrogen in the water.
• 21:00
  SPEAKER_00: And so, sorry, I interrupted you and kind of stole that, but that's really, really cool.
• 21:05
  SPEAKER_00: That's good.
• 21:06
  SPEAKER_02: So, so like you know, going and trying to put a rover down that can measure the hydrogenized subcomposition of the minerals on the surface, as opposed to just when we look at spectroscopically or fly us a satellite through the orbit through the atmosphere, we get a measurement of the current atmosphere.
• 21:22
  SPEAKER_02: And so, how did that change over time?
• 21:24
  SPEAKER_02: Has the H1 to H2, the deuterium to hydrogen ratio of Mars atmosphere changed over time?
• 21:30
  SPEAKER_02: You can look at like hydrated minerals on the surface, alteration minerals on the surface.
• 21:33
  SPEAKER_02: And so some of the really cool mass spectrometer advancements are the sort of micro mass spectrometers that they're putting into orbit.
• 21:42
  SPEAKER_00: Okay, uh question for you then.
• 21:44
  SPEAKER_00: Is radiometric dating a part of this discussion?
• 21:48
  SPEAKER_02: Ooh, good question.
• 21:49
  SPEAKER_02: Not that I know of.
• 21:51
  SPEAKER_02: Okay.
• 21:51
  SPEAKER_00: Although can I give context here a second?
• 21:53
  SPEAKER_02: Yeah, yeah, definitely.
• 21:55
  SPEAKER_02: Uh and then uh I I have an although I have a qualifier to that, but not that I've heard.
• 22:00
  SPEAKER_02: Yeah.
• 22:00
  SPEAKER_00: Of course you do.
• 22:01
  SPEAKER_00: So there somebody is using this technique to date when quartz uh sand was deposited.
• 22:11
  SPEAKER_02: Yes.
• 22:13
  SPEAKER_00: The best way I've ever heard this described okay, go ahead.
• 22:15
  SPEAKER_00: Yes.
• 22:16
  SPEAKER_02: The best way I've ever heard this described it as the quartz getting sunburned, and the more sunburned, the longer it sat in the sun for.
• 22:22
  SPEAKER_02: Which is a great description of this technique.
• 22:24
  SPEAKER_00: But then they can determine when it was deposited because then it gets buried.
• 22:28
  SPEAKER_00: So it's deposited, it gets sunburned, and then it gets buried.
• 22:31
  SPEAKER_00: So they can kind of pigeonhole the point at which the sand was deposited, which normally is really difficult because working through the geology of that, this is really exciting stuff.
• 22:45
  SPEAKER_00: I want to be specific about this then.
• 22:47
  SPEAKER_00: Is the cosmogenic dating that I refer to, like sunburned quartz sand, is that a new advancement?
• 22:54
  SPEAKER_02: No, not really.
• 22:54
  SPEAKER_02: That's been around for a while.
• 22:56
  SPEAKER_02: That's always getting more precise, though.
• 22:58
  SPEAKER_02: So it's like radiocarbon.
• 23:00
  SPEAKER_02: Radiocarbon labs have this massive mass spectrometer.
• 23:03
  SPEAKER_02: I mean, this thing takes up a huge room, not just one room, but many, many rooms.
• 23:08
  SPEAKER_02: And that's always getting more and more and more precise because we can count one carbon-14 out of a million carbon atoms, or we can count one carbon-14 out of a billion.
• 23:17
  SPEAKER_02: And so how well can you count that one atom is kind of the key thing.
• 23:20
  SPEAKER_02: And you need a really big mass spectrometer to do that.
• 23:22
  SPEAKER_02: So that keeps improving sort of gradually, more gradually, though, I'd say.
• 23:27
  SPEAKER_02: Yeah.
• 23:28
  SPEAKER_00: Okay.
• 23:28
  SPEAKER_02: Um that's a a quick and dirty update on mass spectrometer stuff.
• 23:34
  unknown: Okay.
• 23:35
  SPEAKER_00: Well, I mean, it is really, really interesting stuff.
• 23:38
  SPEAKER_00: In fact, it was just today that I came across the I had never thought of it before.
• 23:43
  SPEAKER_00: I'd never heard of it before, of dating the deposition of a layer of sandstone, quartz sandstone.
• 23:50
  SPEAKER_00: I'd never heard of that before.
• 23:51
  SPEAKER_00: And I was just like, wait, what?
• 23:53
  SPEAKER_00: That's no way.
• 23:55
  SPEAKER_00: That is so freaking amazing.
• 23:56
  SPEAKER_00: Like, unbelievable.
• 23:58
  SPEAKER_00: It was exciting.
• 23:59
  SPEAKER_00: So that's a fun day.
• 24:01
  SPEAKER_01: Learning about this stuff.
• 24:02
  SPEAKER_01: See above, pursue your passion because you get to just research your passion all day long.
• 24:08
  SPEAKER_00: Well, no, I I still I'm still in the phase of my life where I have to plan out when I'm gonna take a pee during the day, but you know.
• 24:16
  SPEAKER_02: Well, it's on the horizon when you can actually not plan out your uh bathroom breaks, Chris.
• 24:21
  SPEAKER_00: That's right.
• 24:22
  SPEAKER_00: That's right.
• 24:22
  SPEAKER_00: I look forward to that.
• 24:24
  SPEAKER_02: Uh I think that's a wrap on this office hours episode.
• 24:26
  SPEAKER_02: Keep sending us questions.
• 24:27
  SPEAKER_02: These are great.
• 24:28
  SPEAKER_02: We love answering them.
• 24:29
  SPEAKER_02: We love kind of sitting around stewing about how to answer it best, which ones to link together into an office hours episode.
• 24:35
  SPEAKER_02: It's great stuff, and everyone's asking us great questions.
• 24:37
  SPEAKER_02: So send us an email, planetgeocast at gmail.com, with all of your questions.
• 24:41
  SPEAKER_02: You can visit our website, planetgeocast.com.
• 24:44
  SPEAKER_02: There you can support us.
• 24:45
  SPEAKER_02: You can subscribe, see all of our past episodes with transcripts.
• 24:50
  SPEAKER_02: You can see a couple pictures of Chris out in the field there with his uh what are they called?
• 24:53
  SPEAKER_02: Gym teacher sunglasses on, I think.
• 24:56
  SPEAKER_00: Hey Don, you shouldn't say that because your mom was a gym teacher.
• 24:59
  SPEAKER_02: So that's insulting.
• 25:02
  SPEAKER_02: And if you want to learn all the basics of geoscience in an audio form with the key images you need, go to the first link in our show notes.
