Spring 2012 Update: Fall Chlorophyll Concentration - Northeast Shelf Ecosystem

Though regions of the Northeast Shelf Large Marine Ecosystem often have fall bloom activity, the ecosystem as a whole does not typically have a fall bloom. This depiction of long term trend in chlorophyll concentration is restricted to the data coming from the MODIS Aqua sensor only because of bias between the data from this sensor and the historical data from the SeaWiFS sensor. Though not sufficient to register as a distinct bloom during fall of 2011, there were two distinct peaks in chlorophyll during late summer and fall. Chlorophyll concentrations were more closely aligned to the long term mean at the end of the year.
