Blooms of the toxic dinoflagellate Alexandrium fundyense are annually recurrent in the western Gulf of Maine WGOM and pose a serious economic and public health threat. Transitions between and vital rates within the life stages of A. funedyense are influenced by diverse environmental factors, and these biological dynamics combine with energetic physical motions to yield complex bloom patterns. In this thesis, a biological model of the A. fundyense life cycle developed from laboratory and field data is combined with a circulation model to test hypothesis concerning the factors governing A. fundyense blooms in the springs of 1993 and 1994.
