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.
