Raw data from the benthic macroinvertebrate surveys conducted in Saginaw Bay in 2006-2009, and in Lake Huron, including Georgian Bay and North Channel, in 2007 and 2012. These basic benthic survey data provide number of each taxon in each replicate sample (abundance), density, and biomass.

This dataset is a Moriches Bay benthic fauna study.

The NOAA Northeast Fisheries Science Center has, through the years, accumulated an extensive data base of qualitative and quantitative (wet weight and number per square meter) data on the composition, distribution and abundance (including a variety of environmental measurements) of the macrobenthic invertebrate fauna of the U.S.east coast continental shelf, slope and upper rise ranging from the mouth of the Bay of Fundy to Key West, Florida. Benthic fauna data has been collected from 1881 to the present by the National Marine Fisheries Service Laboratories at Woods Hole, MA (early years Bureau of Fisheries) and Sandy Hook, NJ (formerly with the Bureau of Sport Fisheries). Little data exists from 1881 to around 1955. After intensive sampling, data became sparse again after 1986. The data includes the work by Wigley and Theroux on the macrofauna of the Northeastern United States. Other major studies include Ocean Pulse, the Northeast Monitoring Program, New York Bight, 12 Mile Dumpsite, Long Island Sound and Raritan Bay surveys. Parameters included in these surveys include depth, sediment type, gear type, number, weight, family, class, genus, species name, and abundance. A total of 21,000 sample sites are included in this data set with 4,000 meters being the maximum depth sampled. Bottom temperature from MBTs and XBTs were measured from the 1960s to the present.

This dataset contains metrics of benthic assemblages taken before (pre) and after (post) barrier island restoration of the Mississippi Barrier Islands, which included sand placement on Cat and Ship Islands. The U.S. Fish and Wildlife Service considers the barrier islands along the Mississippi-Alabama coast as critical habitats for certain threated and endangered shorebird species. Barrier islands are inherently dynamic environments, facing frequent natural disturbances and undergoing rapid change. Understanding the distribution and community responses of benthic communities is critical for predicting the impact that restoration efforts and natural disturbances will have on shorebird foraging habits in the Mississippi Barrier Islands. Data were collected at both reference and restoration sites in 2011, 2015, 2020, 2023. Sites were selected based on shorebird foraging habitat, proximity to sand placement, and potential sand borrow sites. The data provided here includes wet biomass, raw density and richness, mean density and richness, and species percent abundance. These data will be used to inform the Mississippi Coastal Improvements Program (MsCIP) Monitoring and Adaptive Management Plan (MAMP).

Benthic organisms data were collected using sediment sampler and net casts BELLOWS and other platforms in the Gulf of Mexico from 16 May 1974 to 20 February 1978. Data were collected and submitted by Dr. William Sackett of Texas University with support from the Outer Continental Shelf project. The data are from field sampling or surveys of bottom dwelling marine organisms in F132 format. The data provide information on species counts and species wet weight from samples collected by point sampling (grab or core) or by tow (dredge or trawl). Three operational kinds of data include: Epifauna, Infauna, and Meiofauna benthic organisms data that roughly correspond to the different sampling methods and collecting institutions that were part of this study. Cruise information such as vessel, start and end dates, investigator, and institution/agency; station numbers, positions and times; and equipment and methods are reported for each survey. Number of individual organisms or total weight of all organisms in the sample is reported for each taxonomic category identified by the researchers (often to Genus and Species taxonomic resolution).

This dataset provides terrestrial, aquatic, and benthic macroinvertebrate data at four sites within Willapa National Wildlife Refuge.
