Spring 2007 Update: Historic Phytoplankton Cycles-Georges Bank
There has been considerable variation in the phytoplankton cycles of the Georges Bank. The timing and intensity of the spring bloom has changed year to year. The concentration was clearly below average in 1998 and 2006 and above average in 2001, 2003, and 2004. There is no obvious trend in the development of the spring bloom. The fall bloom has failed to develop in some recent years (2003, 2004, 2005), which suggests the fall bloom has declined over the time period.
