Mathematical model of oxygen depletion in the New York Bight: an analysis of physical, biological, and chemical factors in 1975 and 1976
A marine ecosystem model of the New York Bight is developed with the model equations describing oxygen depletion, nutrient dynamics, and phytoplankton distributions during the stratified season. The large-scale anoxic event during the summer of 1976 is the problem setting for an analysis of the relative significance of natural physical-biological processes and anthropogenic waste inputs on oxygen depletion in the Bight. The simulation results clearly demonstrate the influence of the flow field reversal during June-July 1976 on the accumulation of the dinoflagellate, Ceratium tripos, and other particulate materials over the New Jersey shelf. The onset, and progression of anoxia across the New Jersey shelf resulted primarily from decomposition of the declining Ceratium bloom within a subpycnocline layer substantially reduced in thickness by the deep pycn
