Plant cover, sediment properties, mollusk abundance and morphology from three Louisiana saltmarshes, 2013-04-04 to 2016-04-28

Snails, oysters, and mussels were collected in three south Louisiana saltmarshes (Terrebonne Bay, Grand Isle, Port Sulphur) from 2013-04-04 to 2016-04-28. In addition to abundances, an assortment of physical measurements were taken for each mollusk species. Plant coverage and sediment characteristics within each collection quadrat is also reported here for samples collected in 2014-2016. Note that 2013 data from these sites are available under GRIIDC Unique Dataset Identifiers (UDIs) R1.x139.144:0021 (mollusk abundances), R1.x139.144:0022 (sediment properties), and R1.x139.144:0023 (plant cover). Invertebrate measurements (not originally conducted on the 2013 samples) were done later and is included in this dataset.
