a Map of the AO showing the shelf seas and central basin. Climatological summer means of b NCP and c e-ratio for 2003–2022. Summer mean d NCP and e e-ratio across the AO and its subregions. In a, subregions are outlined by thin black lines and classified as Basin, Inflow shelves (Chukchi Sea, Barents Sea, and Norwegian Sea), Interior shelves (Beaufort Sea, East Siberian Sea, Laptev Sea, and Kara Sea), or Outflow shelves (Greenland Sea, Baffin Bay, and Canadian Archipelago). Land areas are shown in grey. Inflow and outflow currents are shown as red and blue arrows, respectively. The color bar represents bathymetry in the AO in (a). White pixels in (b) and (c) denote missing data. In the boxplots d and e, the upper and lower bounds represent the first and third quartiles, the whiskers show the minimum and maximum values, while the centre line and open squares indicate the median and mean values, respectively.
