| 00:01 | OK, so I've got the recorder , it's on lips. OK. |
|
| 00:13 | , um, this is what you're do with the chart. The first |
|
| 00:16 | is make that uh water depth chart rather than uh read about this, |
|
| 00:25 | , I'll let you read it, I'll show you what the chart is |
|
| 00:28 | a minute. And the other thing you have to do, which is |
|
| 00:30 | little bit different. You're gonna do , uh you're gonna look at simple |
|
| 00:37 | in depth or by sample number down and I try to make it really |
|
| 00:41 | . Um And uh and then in uh plank to benic ratio, you're |
|
| 00:49 | do a chart and I'll show you example of that and uh, and |
|
| 00:52 | do a uh four M benthic calcareous for m benthic, a glutin ratio |
|
| 01:00 | down hole too. And, and addition to doing uh what I'm gonna |
|
| 01:06 | you, you could also do a . Uh I think you might all |
|
| 01:11 | uh when uh when we had a well plot, there was a, |
|
| 01:19 | there was a channel that had uh the letter designations for the pathy |
|
| 01:25 | , excuse me, not the be pale Hyett zones and uh and they |
|
| 01:30 | kind of color coded but uh you have to color code them, but |
|
| 01:33 | could have like, you know, for marginal marine, a little column |
|
| 01:38 | marginal marine, a column for uh neuritic, middle neuritic, outer |
|
| 01:43 | upper middle and lower bale and then sort of like little channels and you |
|
| 01:48 | plot where you think it best fits it may fit in two of |
|
| 01:52 | It may fit halfway into one and into another things like that. But |
|
| 01:57 | way you could have something that's a that looks like it. And that's |
|
| 02:00 | you could do extra, but you have to do it and that would |
|
| 02:03 | out of item number one. And and then when you do uh items |
|
| 02:09 | two, you can kind of compare you see in terms of diversity and |
|
| 02:14 | benthic, uh the, the calcareous Glutin Benthic Forum uh rat uh ratio |
|
| 02:21 | the simple diversity. So this, way you're gonna be looking at specific |
|
| 02:27 | generic markers and you're gonna be looking assemblage uh structure, especially the |
|
| 02:37 | And then uh briefly describe, and could briefly describe this interpretation, but |
|
| 02:41 | you did one of those columns uh just uh put next to one |
|
| 02:47 | you know, the diversity is very like you would expect in this watered |
|
| 02:51 | zone or something like that. That be helpful too. But uh this |
|
| 02:55 | your look up table chart. I think the uh the bio stratigraphic charts |
|
| 03:02 | here really add anything to it. again, you may have uh, |
|
| 03:07 | that, uh I can see here by gene riders look good. I |
|
| 03:12 | know if you'll even see one of , but uh uh you may not |
|
| 03:16 | the species but you will see some the genre. And if you see |
|
| 03:20 | genre, go ahead and, and plot those on the chart and |
|
| 03:25 | chart that I am talking about is be a blank that looks something like |
|
| 03:30 | . Uh that's in, I think blank is gonna be on the uh |
|
| 03:35 | that at the last part of the lecture? You have a blank |
|
| 03:41 | Yeah, you can plot it out you, or you can make a |
|
| 03:43 | and do it. And what I talking about is sometimes these columns are |
|
| 03:50 | uh squeeze down really close and just like nmmmin kind of like that. |
|
| 03:57 | , and then, then you'll have a few columns in a row like |
|
| 04:01 | . And then you can kinda show you're like here, for example, |
|
| 04:05 | can see you, you've gone from shallow to deep on this one. |
|
| 04:09 | is from a different data set, you should be close to this. |
|
| 04:14 | , uh, and then, and I think this persons discriminating |
|
| 04:18 | um, ah the gluttons and the ones in here and, uh, |
|
| 04:26 | blue and green and the agglutinates are ones out here, I think. |
|
| 04:32 | , uh, but also you might be looking, you can see here |
|
| 04:36 | a big stretch in depth range. lot of times when we do |
|
| 04:41 | uh, this, we'd call an . Uh, but when it's a |
|
| 04:45 | water outlier, I don't like to it an outlier. It was, |
|
| 04:48 | was a outlier on the upper then I might drop it. But |
|
| 04:54 | take a look at like if you a pattern like this, you would |
|
| 04:57 | something in here. I'm not sure this person was doing with this over |
|
| 05:01 | . I'm not sure what that Um But I just wanted to show |
|
| 05:05 | , you'll, you know, if , if you can find 10 genera |
|
| 05:09 | species that fit in this in sample , plot them up like this. |
|
| 05:17 | uh and then in all the other , it just kind of shows you |
|
| 05:20 | it's gonna look like when you do , right? OK. And um |
|
| 05:26 | but then at the end, you make something that looks like compressed channels |
|
| 05:30 | these columns so that you can kind see a real quick like things going |
|
| 05:34 | this shallow, to deep, to deep like that. And uh |
|
| 05:39 | that would be extra, that's how get extra credit. And here uh |
|
| 05:44 | uh this shows you the abundance codes this is gonna be really important. |
|
| 05:50 | This is b the data for the for M for the tin samples. |
|
| 05:54 | uh you can see here and some them there, there are none |
|
| 06:00 | And um here, there's also none . And um, so one of |
|
| 06:08 | things that you can sort out is uh heres A V and what V |
|
| 06:16 | and here is very rare. So one. So when you're doing your |
|
| 06:22 | to come up with, uh your , that would be one specimen rare |
|
| 06:27 | the R would be 22 to So what I would say is use |
|
| 06:31 | middle number. So you see rare three if you see an S it's |
|
| 06:37 | on here. But if you see s for several, um, |
|
| 06:43 | um, if you want, you use 7.5 and for frequent, here's |
|
| 06:51 | to 22 that would be somewhere between or 16. But whatever you |
|
| 06:57 | it'll come out pretty much. The common would be uh 21 to 40 |
|
| 07:02 | would be these numbers. I don't we get uh anything like that. |
|
| 07:06 | don't even, let's see, we don't even get, yeah, |
|
| 07:10 | don't even get common in the Ok. And so here don't get |
|
| 07:19 | when you don't see anything. just leave it blank. It could |
|
| 07:22 | a mistake if someone's trying to come with something but uh in the plant |
|
| 07:29 | ratio here, uh there's a lot benthic and there's no plankton forums in |
|
| 07:37 | . Make sure uh if it was other way around, for example, |
|
| 07:43 | there were um a lot of planks no bnhi, it would be 100% |
|
| 07:50 | and these samples are 100% benic. it might be worthwhile to uh to |
|
| 07:56 | that out over here that uh this 100% benthic. And if, if |
|
| 08:02 | was to get 100% benthic, would be deep or shallow? Ok. |
|
| 08:12 | could be either. So you have look at your other markers, you're |
|
| 08:17 | have a lot of ben to do with. So, um this is |
|
| 08:24 | trying to make sure uh you don't any mistakes and you, you kind |
|
| 08:29 | understand it. Why would this, would this be deep? Go |
|
| 08:39 | dude, that's here. I don't . What about the abundance? Oh |
|
| 08:51 | . There's, there's no forums, plank forums, but why would there |
|
| 08:54 | no plank forums? Because it's OK. It would, it could |
|
| 09:01 | deep. Why, uh why would be no Plank forums in the deep |
|
| 09:11 | ? There's a good reason. Uh reason there would probably be none in |
|
| 09:14 | is if that it was deeper than C CD and they would dissolve. |
|
| 09:21 | . If you see this and it like it's shallower water, then it's |
|
| 09:25 | away from open ocean. It's probably marine. That would be a strong |
|
| 09:31 | marine indicator because they don't like They don't even wanna get near, |
|
| 09:35 | don't even wanna get near 30 parts 1000. OK. And so, |
|
| 09:42 | so sometimes samples that look like I can get really strange interpretations, |
|
| 09:46 | there's a reason for it. And is because if, if I had |
|
| 09:49 | lot of uh gluten its in for example, and a lot of |
|
| 09:53 | gluten that's in here and nothing else would be very deep because the agglutinates |
|
| 09:58 | dissolve in the deep butter. All calcareous things would. So that's why |
|
| 10:04 | kind of. So if you just the benthic ratios, you might get |
|
| 10:08 | by this. This would be a that would fool you. But if |
|
| 10:11 | do the calcareous gluten ones that can you whether, oh this, this |
|
| 10:17 | , this is shallow water and this is deep water or vice versa. |
|
| 10:21 | . So having a different tool to the same problem is how we come |
|
| 10:27 | with uh a good ana, analytical logical uh conclusion on terms of a |
|
| 10:33 | of an interpretation. OK. So wanna make sure everybody does that. |
|
| 10:40 | uh this was, I think this done with uh with Excel. And |
|
| 10:46 | you don't have to go overboard like if you don't have time. I |
|
| 10:48 | , you drew this, like I with crayons, it would work. |
|
| 10:53 | And the final report on this is deadline is not really March. The |
|
| 11:00 | is whenever you can get it done to March. And if you start |
|
| 11:06 | on it now, it might get the way of you studying for the |
|
| 11:09 | . I want you to focus on exam. I think, I think |
|
| 11:13 | whole team both online and here if can communicate with each other, uh |
|
| 11:19 | can kind of help yourselves get through , the data crunching part. Uh |
|
| 11:25 | um graphic correlation exercise is really If you understand it, if you |
|
| 11:31 | understand it, it may take a time. Anybody that thinks they understand |
|
| 11:36 | , be sure you listen to other in case you're wrong. But I |
|
| 11:41 | everybody should try to communicate to make that you all are on the same |
|
| 11:45 | before you waste time spotting it wrong then realizing you did it wrong. |
|
| 11:50 | . I think, I think these perfect exercises for teamwork. This would |
|
| 11:55 | really good if, if we had lot of classroom time to sit and |
|
| 11:59 | on it in the classroom, like we had a lab, a separate |
|
| 12:02 | component and then uh and the other that's, that's for the graphic correlation |
|
| 12:08 | . And then for this one, the same thing you've got these counts |
|
| 12:11 | do and you have to look at charts for the look up chart. |
|
| 12:15 | If everybody would split the task of certain samples. Um, if there's |
|
| 12:23 | samples that have absolutely nothing in don't pick those, make sure everybody |
|
| 12:28 | to do one that has things in to be picked out. Ok. |
|
| 12:37 | , uh, and of course, the first is by noon. The |
|
| 12:41 | it's by noon is because at one you have to start taking the next |
|
| 12:45 | the next, uh, professor will in here the next part of |
|
| 12:47 | And I wanna get you done before . But if anybody has issues, |
|
| 12:52 | me know if anybody, uh, like to contact somebody, um, |
|
| 12:58 | can always email them and ask them , if, uh, they'll let |
|
| 13:02 | share your email. I think you everybody's emails already. So, |
|
| 13:07 | try to be kind to each other work together on it and it'll go |
|
| 13:12 | and, and hopefully everybody will get and you'll go into the exam with |
|
| 13:18 | points or so close to 50 uh, in your pocket. |
|
| 13:27 | And, uh, the, the next part of this is gonna |
|
| 13:33 | , uh, less time and it be a little bit more difficult. |
|
| 13:37 | , um, although, uh, , I don't know, maybe everybody's |
|
| 13:44 | a hard time with this class but hope you didn't. It, it's |
|
| 13:49 | lot of stuff that geologists tend to . Most geologists don't like any kind |
|
| 13:54 | thing that has to do with living like biologists. But I had this |
|
| 13:59 | out they, like, they like better than anything. It's my trail |
|
| 14:04 | . Ok. Thank you. Just , not, no, I'm gonna |
|
| 14:13 | , I'll have all the tables on . Um, well, here's all |
|
| 14:18 | tables. Uh, these, these , this is the data set and |
|
| 14:24 | the, ah, look up table there. Everything that you need is |
|
| 14:27 | here. But, ah, the sheets, ah, on the other |
|
| 14:32 | . Ok. So where do we access to this exercise? I didn't |
|
| 14:38 | it posted. Ok. If you , if you go to the, |
|
| 14:42 | the end of, uh, lecture , there's a blank for it. |
|
| 14:45 | think there's a little bit. it looks like I got it. |
|
| 14:53 | . Well, I'll, I'll go and post the blank forms if they're |
|
| 14:56 | there. And if, if they're else, I'll let you know where |
|
| 14:59 | are, I'll check my files and , I'll let you know by, |
|
| 15:03 | , uh, sometime this evening, think just in case you wanted to |
|
| 15:06 | on it this evening. But my is you're gonna want to take a |
|
| 15:10 | and, uh, ok. I'm sorry, and, and where |
|
| 15:15 | the, uh, the data tables ? Uh, this, this is |
|
| 15:20 | data table for this one. but do we have access to this |
|
| 15:25 | deck? I'm, I'm gonna go , I'm gonna go load this online |
|
| 15:29 | the other stuff when I get back my office. Awesome. Ok. |
|
| 15:33 | you. I put this together this because I, because I thought I |
|
| 15:38 | something that was, uh, simpler what I'd already showed you. Sounds |
|
| 15:44 | . Thank you. Sure. And with that, I think, |
|
| 15:53 | , it's not quite five o'clock, I think it won't hurt if we |
|
| 15:56 | a little bit early. Is it up already? Hey, we're, |
|
| 16:08 | getting up to 70 degrees here We were down to 65. |
|
| 16:16 | anyway, I'm gonna stop the recorder |
|
