Bioe 129L Stella Villegas Seasonal variation of  Megaptera novaeangliae  in the Monterey Bay in 2003-2004  and coastal upwelling Introduction Survey cruises are important in constructing a framework for species  migration, foraging, and mating behavior in relationship to climate and  oceanography over determined periods of time, and are key in their conservation  as they help determine human impact on marine mammal populations.   The data  from these survey cruises focus on the distribution pattern of  Megaptera  novaeangliae  (humpback whale) from Spring 2003 to Winter 2004.   In general,  humpback whales migrate from higher latitudes in summer to lower latitudes in  winter (Witteveen et al 2006).  In the Monterey Bay, they primarily feed on the  rich zooplankton  levels that result from coastal upwelling (Croll et al 2005).  I  hypothesize that the distribution patterns of humpback whales are seasonal  mainly as a result of varying number of food availability from May through  January.   Materials and Methods
