Estimating volumes
Good thing laboratory equipment is always labeled with the volume! Even though I have played plenty with Legos as a child and am fairly good at 3D stuff, my mind…

The ocean really takes on the color of the sky
I guess it’s kinda obvious that the ocean always appears to be the color of the sky. On grey days, the ocean looks grey. If the sky is blue, so…
Swell and wind waves
Sometimes waves are very regular and mostly of the same length. Those are the ones that I usually talk about when I talk about interference of waves. But of course,…
Wavelets on bow wave
The other day (well, the other day when I was still at sea and wrote that blog post. Been quite a while since…), when sailing in calm waters, I noticed…
Watch the dispersion relation in action
Remember how we talked about how waves seem to propagate extremely slowly into that calm patch that occurs when a boat pulls away from a dock? Well, the other day…
Recovering an oceanographic mooring
So in my previous post we deployed a mooring (in fact, those pictures were from the deployment of several different moorings). Now how do we get such a monster back…
Deploying an oceanographic mooring
Do you want to know the full story behind the rope in the mystery picture the other day? On the recent Håkon Mosby cruise, we did a lot of mooring…
Reading the water – a new mystery picture for you!
Back by popular demand: Reading the water in my mystery pictures series! Who knows what’s going on in the picture below? You might recognize a couple of details that might…
Measuring the concentration of dissolved oxygen in sea water – Part 3 of 3 – finding the titration volume by looking at the change in color
So now we have prepared our sea water sample and are ready to start titrating to figure out the concentration of dissolved oxygen. The sample itself changes color with added…
Measuring the concentration of dissolved oxygen in sea water – Part 2 of 3 – the measuring part
So how do we actually measure dissolved oxygen concentrations from the samples we took in the last post? We are using a method called “titration” to determine the unknown concentration…
Measuring the concentration of dissolved oxygen in sea water – Part 1 of 3 – taking samples
Since my task on the recent Håkon Mosby cruise was to measure dissolved oxygen, I will give an overview over how that is done over the next couple of posts.…
Joys of a sea-going oceanographer
So you might have noticed that the last 6 weeks or so all posts had been scheduled ahead and that I was strangely absent. Yep. That’s because I was on…
