Meet Bruiser!

BruiserYesterday (Tuesday) was our first sampling day here at station. We would have gone Monday but if the wind is blowing over 20 knots they don't want us out on the water. Which is fine by us, no one wants to feed the fishy! So since the winds had laid down it was time to head out on our trusty zodiac 'Bruiser'. As you can see Bruiser is kind of a beast! The good news is that since it's such a heavy boat it would take an Orca to flip it, so hopefully I will have better luck here than I did in the Azores! Anyway back to the science, we have two main goals while sampling, first is the lowering of our bio-optics cage and second is collecting seawater samples. Yesterday we lowered our optics cage to 60m and collected water in Niskin bottles at 50, 25 and 10m and then two surface samples. Once we have what we need it's time to head back to the lab and filter the samples. As you can see we have a lovely filtration system setup. Filtration SystemWe use 25mm filters and filter the seawater in incriminates of 100ml until we see pigment on the filters. Right now since the water is so clear there is not a lot of activity so we have to filter more water. This will change as the weather warms and the water livens up as we head deeper into the Antarctic summer. We follow this process twice, once for chlorophyll samples and a second time for HPLC samples. Once we have the filters we store them in either the deep freeze or in liquid nitrogen. And that's a wrap!
