Sewardline_fig1

The upper 100m of along the Seward Line was 0.7°C colder in May than the 15-year mean. Progression of seasonal cycles for plankton was delayed: the spring bloom was partially captured, while the development rates of key zooplankton species was slowed. Sampling in 2013 is embedded in NPRB’s Gulf of Alaska project that will help establish if the Seward Line is representative of the western Gulf. An additional “glacial relict” copepod species was confirmed as occurring in Prince William Sound using molecular techniques.
