Description:The COE proposed five research objectives to study the variations in wetland development at the three islands. The objectives included: 1) determination of topographic elevations, 2) mapping of plant species, 3) comparisons of wetland elevations to fluctuating water levels caused by daily tidal and seasonal river-flow changes, 4) sediment analyses for vegetated and nonvegetated intertidal sites, and 5) descriptions of benthic invertebrate communities at vegetated and nonvegetated intertidal sites. In mid-1992, the National Marine Fisheries Service (NMFS) agreed to cooperate with the COE to complete Objectives 4 and 5 at Miller Sands, Jim Crow Sands, and a remnant intertidal marsh in Grays Bay, which is adjacent to Rice Island.
