Progress is reported in the research program which concentrates on sediment bottom communities of the Eniwetak lagoon. Biological and physical-chemical processes of the lagoon floor are relevant to radionuclide mobilization and redistribution. Because of the paucity of general information about the deep lagoon, initial studies were designed to assess benthic community distribution and structure. Two-hundred stations throughout the lagoon are being surveyed using a camera system designed and built at MPRL. These studies of benthic community distribution are augmented by a concurrent research effort to quantify benthic primary production, community metabolism, and cycling of nutrients between the sediments and the overlying water column. Net daily oxygen and nutrient flow data are tabulated. Facilities are described, community relations are discussed, and a plan for future research is given.
