Fig. 2: Climatology of terrigenous nitrogen input, ocean net primary production and remineralisation in the Arctic Ocean over 2005–2010.
From: Around one third of current Arctic Ocean primary production sustained by rivers and coastal erosion
Climatologies of a basin-wide terrigenous nitrogen input from rivers (blue) and coastal erosion (brown) and of b total basin-wide integrated net primary production (NPP) (green) and pelagic and benthic remineralisation of organic matter (red). Total NPP and remineralisation are indicated as dashed lines (Baseline simulation) while NPP and remineralisation only driven by terrigenous inputs are shown as solid lines (computed as the difference between the Baseline and NoTerr simulations). The envelopes represent a uncertainties for the terrigenous nitrogen input (see methods) as well as b the simulated interannual standard deviation of NPP and remineralisation over 2005–2010.
