The waters affiliated with the Blob continue to be present along the entire Seward line with surface temperatures above 6.5 to 7°C (43.7 to 44.6 °F) for most of the transect. This amounts to temperature anomalies of ~1°C (~1.8°F) in the upper 100 m of the water column.
Note: Temperature anomalies represent the difference between the longterm average temperature for a given location during a particular month compared to a value or average for the same month but only for a single year.
This plot shows temperature data from the Spring 2015 Seward Line Hydrographic Survey. The mouth of Resurrection Bay is to the left, and offshore towards the right. Data shared by AOOS Partner Dr. Russell R. Hopcroft, Institute of Marine Science, University of Alaska Fairbanks.
