From silk to satellite: half a century of ocean colour anomalies in the Northeast Atlantic
Abstract Changes in phytoplankton dynamics influence marine biogeochemical cycles, climate processes, and food webs, with substantial social and economic consequences. Large‐scale estimation of phytoplankton biomass was possible via ocean colour measurements from two remote sensing satellites – the...
