Establishing a global climatology of marine phytoplankton phenological characteristics

摘要: [1] The timing or phenology of the annual cycle phytoplankton biomass can be monitored to better understand underpinnings marine ecosystem and assess its response environmental change. Ten-year, global maps mean date bloom onset, peak concentration termination duration were constructed by extracting these phenological metrics from Generalized Linear Models (GLM) fit time series 1° × daily estimates SeaWiFS chlorophyll concentrations dating September 1997 December 2007 as well MODIS July 2002 2010. The fitted models quantitatively define throughout ocean which a baseline characteristics was extracted. analysis revealed regionally consistent patterns in shape that are broadly with other published studies. results showed single predominates over secondary, autumn blooms being limited both location spatial extent. Bloom tended zonally consistent, but meridionally complex did not become progressively shorter increasing latitude is sometimes depicted. Both climatologies used future studies detect significant departures time.
