Intertidal Soft-Sediment Bivalves from Prince William Sound, Kachemak Bay, Katmai National Park and Preserve, and Kenai Fjords National Park These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe bivalve count and size sampling and observations conducted at intertidal soft-sediment sampling sites in the northern Gulf of Alaska. This dataset consists of five comma separated files (.csv): 1) bivalve taxonomy table, 2) bivalve sampling site table, 3) bivalve count table, 4) bivalve size table, and 5) list of Gulf Watch Alaska principal investigators and collaborators.

Macroinvertebrate community samples were collected using bottom-deployed multiplate artificial substrate samplers and organisms were identified to the lowest practical taxonomic resolution and used to calculate metrics of biological integrity following standard New York State Department of Environmental Conservation procedures. Bed sediments were collected using a petite Ponar dredge and used for toxicity tests with two test species, Chironomus dilutus and Hyalella azteca, following USEPA test methods...

During the first sampling effort, bed sediments were collected at 60 sites in the Niagara River, 5 sites on lower Smoke Creek, and 6 sites on Hoyt Lake for use in sediment toxicity testing and determination of grain size distribution and total organic carbon concentration. Additionally, macroinvertebrate samples were collected from the 60 sites on the Niagara River. During the second sampling effort, bed sediments were collected at 10 sites on lower Smoke Creek (5 of which were...
