Moderate-Resolution Sea Surface Temperature Data and Seasonal Pattern Analysis for the Arctic Ocean Ecoregions

Table 2. SST metrics used in analyses presented in this study.

[Definitions explained by this table are referred to throughout the text]

SST analysis metric	Metric description	Metric dimensions
Derived SST values	SST values derived from PFSST product. Each value represents a monthly mean for each grid cell	1 value per grid cell of acceptable quality, 1 raster per month over 29 years (340 rasters)
Monthly-mean SST per ecoregion	The 29-year average of all of the derived SST values (above product) within an ecoregion for each of the 12 months.	20 ecoregions × 12 months
Mean annual cycle	12 monthly means for each ecoregion	20 annual cycles (fig. 3B)
Range of annual cycle	Difference between warmest (maximum) monthly mean and coolest (minimum) monthly mean per ecoregion	20 ranges
Mean annual SST (29-year mean)	Mean of the monthly mean SST per ecoregion over the 29-year period	1 value × 20 ecoregions
Variance in SST	Variance of all derived SST values within an ecoregion over the 29-year period	1 value × 20 ecoregions
