The POPs team is filtering air and water samples to measure persistent organic pollutants (POPs) that may be in this area. We have also collected snow samples in the search for POPs. We have gone to two sites: Old Palmer Station (which was the main station site in the mid to late 1960' s) and Torgersen Island.

We have collected snow from each of these sites two different times. So, we went to Old Palmer twice to get snow, and we went to Torgersen Island twice for snow, also. Each time we have shoveled snow into two 60-liter containers. We bring these containers back to the lab. The snow is melted, and we get about 38 liters of water from each container. Then the melted snow water is filtered just as we filter the water samples we take from the ocean. The water is filtered under pressure through an XAD bead resin column. The columns will be taken back to Virginia for analysis.

These are the pots into which we shovel the snow. Each pot holds 60 liters.

This is the filtering apparatus for water from the ocean as well as from melted snow.

We did not go ashore at Old Palmer. We just shoveled from this snow bank into the containers while we were on the Zodiac. It is hard to tell how deep the snow is from this photo. You can see the blue cache barrels in the background, and they are about 3 feet high.
