| Summary: | Developing an optical classification-based chlorophyll (Chla) retrieval algorithm for the Arctic Ocean by matching in situ and remote sensing data. The statistical relationship between mixed layer depth integrated primary productivity (NPP) and sea surface Chla was also regressed from a large field measurement data set. Through principal component analysis and correlation analysis, NPP environmental driving factors were analyzed. Data sets include remote sensing reflectance data used to invert NPP and environmental drivers of NPP changes. ... : Net primary production (NPP) in the Arctic Ocean has increased in recent decades. However, the specific local and remote drivers and mechanisms responsible for this continuous rise remain unclear. Here, we developed an algorithm based on chlorophyll a data to derive NPP from ocean color satellite observations and constructed a long-term series of NPP data in the Arctic Ocean to assess the spatial and temporal variation patterns and potential regulating mechanisms of NPP. The results indicate that the increase in NPP is primarily due to the influence of shelf areas impacted by inflow water. Using principal component analysis and correlation analysis, we quantitatively analyzed the association between the recent rise in Arctic NPP and increased subarctic ocean inflows, which enhance Arctic NPP through improved heat and nutrient availability. From 1998 to 2008, the increased inflow water volume accelerated sea ice melting through thermal effects, resulting in a larger open water area and extended periods for ... |
