    dct:description "These data are in seven tables relating to surveys of eelgrass beds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass. These tables also provide information on percent cover and location of eelgrass and seaweeds/bluegreen algae, biomass of eelgrass, presence and absence of selected invertebrates, and environmental conditions during the survey." ;
