This paper compares a recent atmospheric wet deposition record (including all measurable daily rainfall events between October 1988 and June 1991) with concurrent measurements of nitrogen cycling and biomass at the U.S. Joint Global Ocean Flux Study Bermuda Atlantic Time Series Study station. The two data sets, among the most complete synoptic records of atmospheric nitrogen deposition and ocean nitrogen cycling, provide an opportunity to directly assess the importance of nitrogen deposition in the ocean. The results indicate that individual nitrogen wet deposition events are usually small compared to the ambient nitrogen cycle and that only under sustained calm conditions following large deposition events will nitrogen deposition processes be an important signal for the understanding of ocean biochemistry. 46 refs., 7 figs.
