Textural composition of shallow cores from the tidal Potomac River and Estuary; 1978 and 1979
During 1978 and 1979, 37 cores were collected by divers from the tidal Potomac River system and from adjacent marginal embayments. These cores, approximately 1 m in length, are representative of geomorphic divisions within the riverine, transitional, and estuarine parts of the Potomac and of several tributaries. X-radiographs were made of an unsampled half of each core. The cores were subsampled at selected intervals for textural analyses. The textural data presented in this report are being used to complement trace-metal, nutrient, and sedimentation studies in the tidal Potomac River system.
