Data on the distribution and abundance of submersed aquatic vegetation in the tidal Potomac River, Maryland, Virginia, and the District of Columbia, 1985

This report summarizes data on the distribution and abundance of submersed aquatic vegetation collected in the tidal Potomac River during 1985. Plant species were identified and dry weight determined for selected sites. Information on competition between Hydrilla verticillata and other species was measured. Water-quality characteristics measured include temperature, specific conductance, dissolved oxygen, pH, and transparency as indicated by Secchi depth. A map was made of the distribution of submersed aquatic vegetation based on transect samples and a complete shoreline survey. (USGS)

Data on the distribution and abundance of submersed aquatic vegetation in the tidal Potomac River and transition zone of the Potomac Estuary, Maryland, Virginia, and the District of Columbia, 1983-1984

Data on the distribution and abundance of submerged aquatic vegetation were collected in the tidal Potomac River and transition zone of the Potomac Estuary during 1983 and 1984. Plant species were identifed on transects. Water-quality characteristics measured include temperature, specific conductance, and Secchi depth. Maps were made of the distribution of individual species based on transect samples and a complete shoreline survey. (USGS)
