Sediment processes monitoring data report for calendar year 1989

During the latter half of the 1980 the Chesapeake Bay Program developed a three dimensional water quality model of Chesapeake Bay for use in assessing management strategies. Because sediments are known to be a large sink of nutrient materials and they are trapped in estuaries due to the circulation patterns, it was important that the model incorporate sediment-water column interactions. The work detailed in this report was designed to measure the flux of particulates and associated materials from the water column to the bottom sediments. During 1988, measurements were made only at the lower Bay station. The data for 1988 have been reported previously (Wetzel & Neilson, 1989).
