Trends in ocean surface phytoplankton bloom properies from ocean color remote sensing

To characterize mid- to long-term changes in ocean surface chlorophyll-a concentrations over the entire Arctic Ocean. It is result of calculating trends in bloom phenological properties through surface chlorophyll-a concentration (SChl) data from the OC-CCI and GlobColour datasets, a merged ocen color products from 1992 to 2022. The analysis is based on 13 subregions in the Arctic Ocean for which the data coverage of the dataset allows for a valid estimates, see the attached map for the exact location of each subregion.

Analysis Data KPDC_Data1.png Bar plots of trend in (a) mean SChl (SChlmean, mg m-3 yr-1), (b) maximum SChl (SChlmax, mg m-3 yr-1), (c-d) first and second bloom amplitude (BA, mg m-3 yr-1), (e-f) first and second bloom peak timing (Tmax, days yr-1), (g-h) first and second bloom initiation timing (Tint, days yr-1). The blue and red represent OC-CCI (OC) and GlobColour (GC) results, respectively. The error bar indicates the standard error of the slope in the regression analysis, which was calculated by dividing standard deviation of residual (original y-predicted y) by √(∑(x-x ̅)^2 ). 213.56 Kb Request required
