| Abstract: | It has been hypothesized that there is a positive correlation between an increase in the molybdenum content of seawater and the onset of dinoflagellate blooms, commonly known as red tides. This hypothesis is based on the fact that red tides in Western Florida waters are often preceeded by blooms of certain nitrogen-fixing alagae, which require molybdenum as part of the nitrogen-fixing process (Martin 1983). Tests were conducted in an attempt to determine if molybdenum is an essential micronutrient and, if so, determine at what level it becomes limiting for RG-1 dinoflagellates. No correllation was found between the presence or absence of molybdenum and the growth of RG-1. |
