July 27, 2007 Location: Gulf of Saint Lawrence, South of Anticosti Island Greg showed Andrea and I where to get "Flow-Through" water samples while on board, in a small lab on the port side stern next to the Paleo Lab. Two scientists there are using the "Flow-Through" system to sample ocean water continuously while we travel, they are using resin filters to collect contaminants. We get to use the leftover water, which is not much. It took Greg almost 20 minutes to rinse three 2 liter sample bottles three times each, then fill the bottles. This is because the majority of the water available is being used and the system needs a bit of work. Since it is necessary to record latitude, longitude and UTC, we either use a handheld GPS or call up to the wheelhouse (bridge). We took the samples to our lovely lab, #610, down 5 floors from the bridge, on starboard side bow. It is actually quite spacious for us because the 2 other teams who will use the lab on other legs of the voyage are not here for leg1. Greg helped us get out all of the necessary equipment and ran us through the process of filtering water samples. Andrea had done at least some of this before, I had done none of it - I took notes and photos! (It seems fairly straightforward and quite interesting, I hope I get the hang of it!) Most of the analysis of the filtered samples will take place later, at other labs. |
