Data from reference was extracted using WebPlotDigitizer. The quantitative value is the average of reported density values of Puffinus tenuirostris during the research cruises throughout the study period, from August 3 to September 19 and October 1 to October 8, during open water season. The seabird survey was conducted following survey lines aligned from north to south spaced 2 NM apart. Puffinus tenuirostris were observed to have a slight preference for Bering Sea Water, which only extended to the Klondike study area in 2008 and all study areas in the latter years (Ref 118567). |
