Surveying

After all the surface sampling was done, there were two days scheduled for surveying beach transects. We survey the same lines each year to see if the beaches have lost or gained sand, and by approximately how much. On the first day, I was needed for this. And low tide wasn’t so frightfully early anymore, so Stef (the technician) and me picked up the students at 7:00. We drove them to HQ, where Martin divided the students into three groups (we would do three transects) and we loaded up the kit. 

Once parked we each headed to our transects. I thought I knew where the start of ours was, marked by a wooden post. Without problems we walked to where I thought it was. I didn't see a post. I must have been mistaken. We kept walking, but it soon looked like we had overshot it. We then looked at the GPS; we knew its coordinates. We found the GPS a bit clunky to work with. While we were struggling, I sent one student north and one south, to see if they could just spot it by eye. No success! But then we managed to get the GPS to do what we wanted, and could, with its help, just walk towards it. And it brought us straight back to where I thought it would be in the first place. And then I suddenly saw it. It was the most obvious wooden post in the world! How could we all have missed that? And some of us several times?

We had lost some time this way, so now we needed to get moving. The beginning of a transect like that is always slow, because the temporary benchmark is placed out of reach of the incoming waves, so in the dunes, quite high up. That means you have to move your tripod a few times to get it into a position from where you can survey large parts of the beach. 

Even though all the students had been complaining they had learned to survey a million times, the start was a bit slow. The students were trying to get their head around what exactly it was they needed to note down, and where. But in the end they got it, and then I figured we would speed up. And we did.

Surveying on a sunny and windy beach

With the students being more confident we got to the waterline; here we obviously had to turn around. With big steps we headed back to our benchmark. From WhatsApp I found out that the other groups were already done.

We made big strides back. Soon we were close to the benchmark again. I eyeballed it and figured it was about a meter above instrument height. Our documentation suggested otherwise. Hmm. Had something gone wrong? We looked back at all the numbers that had been written down. Was something miscalculated? 

By then we were tired and windswept and brains were not firing at full speed. When the students were certain they had all the necessary numbers to be able to recalculate we packed up and went back to the vehicle. 

Once back at HQ the students could bring the paperwork in order in comfort. I had a drink and a sandwich. After a while the other students got impatient as they had finished well before my group. And we were in several vehicles so they left. My group got it sorted, and then we could leave as well. Another part of the field trip done and dusted! 

Digital access issue

The university has to deal with the changing world. One thing that changes is the increase in cyberattacks. Back in them days, you just logged in. Then, two-step verification came in. Initially, you didn’t have to confirm that often. Now you do. And I always had a code sent to my mobile phone. The other option was to use my mobile Outlook app. It should let you enter a code, but mine never did. But that was not a problem, as there was an alternative. Until there wasn’t.

One day the SMS option just seemed to vanish. And without it, I can’t log in. I tried to check something for the fieldwork and failed; when I told Martin about that, he seemed to know what was going on. He said I must have missed some emails about this; he said they hadn’t been particularly obvious. But they said that we now all needed to use an Authenticator app. That would explain things.

I found the right app in the App Store and downloaded it. Then I tried to link it to my work account. Guess what? You need two step authentication for that. How would I get that? 

When I got to campus after a morning in the field, I went to my office and first had a look for the emails I seemed to have missed. To my embarrassment, the earliest mention of it was from years ago. But there were only two, over the last six years or so. Possible to miss. But reading them didn’t help me. I phoned the helpdesk. 

To my relief, the person answering said he could sort this. He did a remote log-in on my computer, and that way managed to link the app to the account. And it works now! That was a big relief. I might be up to date-adjacent now. The times will inevitably catch up with me again, but maybe not for a bit of a while now! 

It works! 

New bits for bread machine

Over three years ago, I bought my current bread machine. And since then, it has baked a loaf for me almost every second day. That is over 500 loaves. That must show. And it does.

One thing that happened is that the anti-stick layer of the bread pan deteriorates over time. It gets harder to get the bread out. Another thing is that the bread pan is made of fairly thin aluminium, and when the machine is kneading dough, the dough is pushed strongly in one direction, which inevitably means that something is applying force the other direction. And by the looks of it, this slowly distorts the pan. Mine started out rectangular, but is now more a parallelogram. And I am sure this contributes to that it is getting increasingly difficult to get the bread out.

I didn't automatically assume you could buy them separate; I didn't even expect it. But it was worth having a little google to check. Lo and behold; you can! So I ordered a new bread pan and it soon arrived. It is a bit higher than the other one, but it does fit my machine. And it works! It is lovely and easy to get the bread out. I'll just have to adjust the settings; with identical settings, you get lighter bread with new pan.

The old and the new

Another issue is that the shaft that drives the kneading paddle is more or less the shape of a half circle. The pedal has a similarly shaped cut-out. Initially. But the shaft is clearly made of harder metal, and it is on a mission to erode the material of the paddle away until in the end, the half circle has turned into a circle. And then the whole machine doesn't work anymore.

I should have ordered them at the same time, but I wasn't quite switched on enough to do that. I ordered a new paddle separately. And a message it had been delivered arrived soon. But there was no sign of it! A bit like my initial cabinet door handles. What a nuisance. 

I don't know how this will pan out; I hope they will send me a replacement. But I think the paddle will last long enough to allow me to keep baking while this situation is being resolved; let's hope at least that will be the outcome. At least I have my pan!

I also hope is that the actual machine keeps functioning for a while. It would be sad if I had a new pan and a new paddle, and then the actual bread machine gives up the ghost! Let's hope not…

Surface sampling

Low tide was at 7:17. I need low tide for my sampling, This would be an early start! And I would have to pick the students up from Bangor. That meant: getting up at 5:00, leaving the house at 5:30, load up the hired vehicle at 5:45, picking up the students at 6:15. We could then be at HQ at 6:45, and in the field by 7:15. Perfect timing! Jaco would pick up his students (basically, all those not coming with me) at the same time. And because of the student members, we needed a third vehicle, with some of his students, and some of mine.

It didn't quite work that way. One student had overslept and was only there at 6:30. I had picked up my gear, not Jaco’s; I figured he would do that himself. That was a misinterpretation. Our technician, driving the third vehicle, didn't pick it up either so someone had to get back for it. We didn't have the key for HQ, so we got there for no reason. It was a bit complicated!

In the end we all got to where we need to be, and the tide was still fine. I had discussed with the students where we would take a transact of sediment samples. And that had been conveniently close to parking.

It was a bit misty, but it was dry, and the temperature was pleasant. Perfectly fine fieldwork weather. On the way into the estuary we looked at the environment we came through, and chose which ones we wanted to sample. And when we decided we had been as far as we wanted to be, we tried to survey in the location I took the first sample. I couldn't make the GPS reach its normal accuracy, but it would have to do. At least the sampling went well. We made sure that only take as many samples as we have sieve stacks. That is novel; normally, I make every student take a sample. But this is quite a big class, and that seemed excessive. Fewer samples means less work for everyone.

The estuary 

When we were done, I was quite keen to get to HQ. We could; Martin was there by now. And a few students were keen on a coffee. I would take my student to the lab afterwards, and of course, in the lab, you can't eat or drink. So this was our chance. I also wanted to ask Martin a few things. Jaco and his students were done for the day, so they were more keen to go back to campus. So two vehicles went straight back to campus and mine went past HQ. 

It was about ten o'clock when we reached HQ, and I had had breakfast at five. I was quite desperate to consume something. One of the students handed me a coffee and I was very grateful. And I had half my lunch. I also go to ask Martin everything I needed to ask, so after that we could go.

In the lab, all went well (except one mishap with the handle of an oven.) With only seven samples to sieve, and the students really being quite executive about it, we were done quite soon. And then Stef, our technician for the day, offered to bring all the students back to main campus. That was great! That saved me driving there and back. Why use two vehicles when you can use one.

In the office I could do all these other things need doing, and when I was done, I could take the rental vehicle home. Nobody else needed it the rest of the day. And that meant I could drive straight from home to where the students are picked up the next day. That would save me at least half an hour!

The day after had the same schedule. And mostly similar weather, although this time we caught a little shower. The students were quite responsive again. And this time, I got the GPS to work well. 

The work in the lab was quick, like the day before. And again, Gareth took all the students back to Bangor so I didn't have to do that. And I processed the samples of the day before. Well before lunchtime I was done! So that was pretty much it for the surface sampling. Popping back into the lab process the second batch of samples will not take long. Onwards to the coring! 

Field trip starts

We the geosciences-oriented people always start term two weeks before everybody else, with the Newborough filed trip. And this year, the weather forecast for the start of the field trip was absolutely rubbish. In the morning before I left it was bucketing down. I also drove in through rain. The students, who had been asked to gather on the Ocean Sciences campus, had sought refuge in one of the buildings.

Martin took attendance and then we could all get into vehicles, to get to Newborough. We have fieldwork HQ there. And by the time we got there, it had stopped raining!

Martin said some introductory things, and suggested that we might as well have lunch before we go into the field. We left at noon.

As usual, we went to Malltraeth first, to have a look at the landward end of the estuary. But it was high water spring tight, so there was less to see than normal. Then we went into the saltmarsh. I did my thing there. I told him about why these environment are important, and why foraminifera are important too. 

I thought we would then go to where we take our sediment cores, but we didn't; we went all the way to the other side of the estuary. Martin pretended it was on purpose. Dei knew he had just missed a junction. Never mind! We had a good look at the beach and the dunes and how the beach is different on either side of Llanddwyn island and where the waves break.

By then it was time to go back to HQ. We skipped the coring location altogether. Fine with me. 

Back at HQ, Dei reminded all the students of how to survey. It turns out that they had almost all learned this already, more than once. He did it anyway. And then we could go back to SOS. 

The atmosphere in my vehicle was good. I had the impression the whole group was quite engaging. Great! Sometimes you get quite a number of very unresponsive students, and I find that rather disheartening. 

In Brynsiencyn we saw two hitchhikers. We had two spare seats. I asked the students if we should pick them up, and they said yes, so we did. They turned out to be German tourists, housesitting for someone in Tregarth.

We got back to SOS. That was the end of the first field day! The next one will be a lot more hard work. But so far so good. And in my own car I brought the hitchhikers to the recommendation and then I could go home. Time to eat pizza with Neil! And the day after, I wasn't needed. I could use this Sunday to get mentally ready for the Monday, which was going to be a day with a very early start… 

Phone problems

I like phoning my mum on a regular basis. I have an international phoning app, which is cheaper than just normal phoning. But it started playing up. First it wouldn't let me phone my dad, but at least there is a workaround as I can FaceTime his wife. Then it wouldn't let me phone my mum anymore either. I have no idea why.

One night I decided to just phone my mum anyway, but the direct way. Yes it is more expensive, but it is important that I manage! It worked once. But then just phoning her resulted in the same refusal from the phone. And she doesn’t do WhatsApp or FaceTime or email or any of that, so if I can’t phone her, I can’t let her know I can’t phone her, except by snail mail. 

I was wondering if it was my phone. By phone standards, it is old. It does more quirky things. Neil didn't believe it. He thought it might be something with the SIM card or with the provider. 

When I couldn't phone my mum at all, I did some more fanatical googling. Why couldn't I do this? I got nowhere with the international phone app. I tried some phone settings and rattled the SIM card. I googled if maybe there are alternative apps I could use. When I couldn't phone my dad anymore I had already googled that, with little result, but maybe I hadn't looked hard enough. I got nowhere.

The next day I did log into my account on the website of my provider, and I noticed that it seems to have merged. It used to be O2, and now it is Virgin Media O2. Might that have something to do with it? Did something change with the conditions?

To be on the safe side, I sorted an international calling bolt-on, and raised my spending limit. Even though I think that if this was a money problem my provider is an idiot. If someone is trying to make a phone call and they ran out of budget, surely the thing to do is disconnect the call and then display a message that says “you ran out of budget; go here to top up or change your allowance”. I mean, I want to make a call and they want to earn money; why not enable both? 

Either way; I hope I have sorted it. But if not; I asked my future killer AI for advice regarding useful apps. It found things I hadn’t, and they looked useful. I still have my old phone but I may be in business again! 

Threat of AI

When it is on the news that AI insiders are warning that there is more than 10% chance that AI will kill us all within 10 years, that is a reason to worry. Have I heard some people claim that this is a publicity stunt? Yes. Is that thinkable? Also yes. Unfortunately, it is also quite thinkable that they mean it, and that they know what they're talking about.

Some months ago I had a discussion with Neil about this. He wanted to know what could go so wrong. I didn't know the details. But what I had done was read a review of a book that goes into detail about these things: If Anybody Builds It, Everyone Dies. I bought the book, and gave it to him. I told him to read that rather than ask me questions. He's not finished it yet, but when he has, I'd like to read it myself. Not in order to feel reassured! Maybe more to know what to get mentally ready for.

I remember that many years ago, I read in the newspaper that some scientist in the know said that the next big disaster to happen to humanity would be a pandemic. They said it was pretty much inevitable. They just didn't quite know when it would happen. And I must say that when COVID-19 broke out, I did appreciate it I had had advanced warning. This could be the same thing.

Will we be killed by AI? I don't know! One way to find out. I really wouldn't put it past humanity to let it get this far. And that would, obviously, be sad. But if it happens, at least I think I will have lived longer than most people, ever. So I could consider myself lucky…
