#ScienceatSea TAS 14 Greg Cook from Massachusetts is at sea this week on board NOAA Ship Oscar Dyson (with TAS Kacey Shaffer.) Greg describes that the pollock survey doesnt collect data only about pollock: Hanging on the side of the Marinovich are smaller “pocket” nets. Nate explains to me that, while we are mainly studying Pollock, there’s other valuable data that can be gleaned (collected) in the process. Other scientists studying Krill populations will be grateful for the data. The pocket nets are labeled, and each net is placed in a labeled bucket. Then I grab a pair of tweezers and start sorting. It’s mostly krill… skinny shrimp-like organisms with beady black eyes. These tiny invertebrates, altogether, make up millions of metric tons of biomass. - TAS Greg Cook tinyurl/pwjy9c8 Top photo: The first trawl brought up mainly jellyfish.
