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.

Densities of major taxonomic groups and species (or higher taxa) of benthic macroinvertebrates sampled in lake-wide surveys of Lake Ontario conducted in 1994, 1997, 1998, and 1999. This dataset is associated with the following publication: Burlakova, L., A. Karatayev, A. Hrycik, S. Daniel, K. Mehler, L. Rudstam, J. Watkins, R. Dermott, J. Scharold, A. Elgin, and T. Nalepa. Six decades of Lake Ontario ecological history according to benthos.. JOURNAL OF GREAT LAKES RESEARCH. International Association for Great Lakes Research, Ann Arbor, MI, USA, 48(2): 274-288, (2022).

This data set contains a single table of descriptions of benthic samples collected in 1998 at Nelson and Izembek lagoons, Alaska. This includes: the weight of the sample, the species or species group of benthic animals (also vegetation) and their number, size and weight, and the amount of sand and gravel. These data provide a basis for additional studies that includes sampling of the benthos in Nelson and/or Izembek lagoons. These data are important as historic information useful in examining long-term changes in the lagoons in light of changing climate.

To examine biodiversity trends over time, a master list was compiled of all benthic invertebrate species collected from the Narragansett Bay beginning with Totten’s 1834 descriptions of mollusks, Leidy’s collections in 1855, Verrill and Smith’s surveys beginning in 1871, and studies at Alexander Agassiz’s Newport Marine Zoological Laboratory, 1873–1910. The list, spanning 182 years, was compiled from 104 sources and includes invertebrate macrofauna (>0.5 mm) and more limited studies of meiofauna. It currently holds over 1,200 unique taxa from 21 phyla. Information given for each collection record includes: current accepted scientific name, when and where sampled, by whom (with citation), gear used, and full taxonomic hierarchy. This dataset is associated with the following publication: Hale, S., M. Hughes, and H. Buffum. Historical Trends of Benthic Invertebrate Biodiversity Spanning 182 Years in a Southern New England Estuary. Estuaries and Coasts. Estuarine Research Federation, Port Republic, MD, USA, 41(6): 1525–1538, (2018).

The two excel files provide zooplankton and benthic macroinvertebrate data, respectively, underlying the publication. The data consist of sample by taxa matrices for Isle Royale in 2012, Apostle Islands in 2017, Lake Superior CSMI in 2016, and Lake Superior NCCA in 2015. This dataset is associated with the following publication: Trebitz, A., G. Shepard, C. Meredith, G. Peterson, and J. Hoffman.
