摘要: On each of a 4-month series weekly cruises in Kaneohe Bay, Oahu, Hawaii, vivo chlorophyll was monitored continuously by fluorometry, and at 8 stations discrete measurements (trichromatic method), primary productivity (14C), nutrients (nitrate phosphate) were made. The results are compared with similar data collected decade earlier the bay to investigate enrichment effects increased waste discharge over this period. south sector bay, site two sewage outfalls, showed greatest population instability had highest concentrations a, nitrate, phosphate, as well productivity. Chlorophyll, nutrient concentration, decreased through transition into north which is farthest removed from points. index (mg C fixed hr−1 mg Chl a−1) no such differences. A model simplified food chain using hyperbolic relationship between uptake rate substrate concentration postulated explain dynamics plankton community bay.
