Glacier Bay National Park and Preserve Sea Otter Forage Data, 1993-2019 These data describe observations of sea otter foraging behavior in Glacier Bay National Park and Preserve. Data consist of dive and surface times, success in prey retrieval, prey item, prey quantity, and size. Additionally, location of observations, and age class, sex, and pup status of the focal sea otter were also recorded.

Missouri River Benthic Fishes Study (MRBFS) documented annual patterns, habitat, and water quality associations of 21 Missouri River benthic fish species based on relative abundance, including sicklefin and sturgeon chub from 1996 to 1998. Data sets include capture data and habitat characterization. The objective was to evaluate population structure and habitat use of benthic fishes along the entire mainstem Missouri River, exclusive of reservoirs.

This dataset consists of six comma separated files (.csv): 1) mussel sampling site layout information, 2) mussel counts for mussels greater than 20 millimeters in a quadrat, 3) mussel size measurements for mussels greater than 20 millimeters in a quadrat, 4) mussel counts for all mussels collected from core samples, 5) mussel size frequencies for all mussels collected from core samples, and 6) list of Gulf Watch Alaska principal investigators and collaborators.
