Data from the Chemical Analysis of Archived Stream-Sediment Samples, Alaska Data from the Chemical Analysis of Archived Stream-Sediment Samples, Alaska
This data release contains the elemental concentration data for more than 1700 archived stream-sediment samples collected in Alaska. Samples were retrieved from the USGS Mineral Program's sample archive in Denver, CO, and the Alaska Division of Geological and Geophysical Surveys Geologic Materials Center in Anchorage, AK. All samples were analyzed using a multi-element analytical method...

Sea Otter Aerial Survey Data from Northern and Eastern Prince William Sound, Alaska, 2014 Sea Otter Aerial Survey Data from Northern and Eastern Prince William Sound, Alaska, 2014
This dataset consists of three tables related to abundance and distribution of northern sea otters (Enhydra lutris kenyoni) in northern and eastern Prince William Sound, Alaska, based on data collected during a series of population-wide aerial surveys in June 2014. The dataset consists of: (1) sea otter counts along strip transects, (2) sea otter counts in Intensive Search Unit (ISU)...
Experimental evaluation of predator exclosures on nest, chick, and adult survival data for the Northern Great Plains piping plover, 2014 - 2016 Experimental evaluation of predator exclosures on nest, chick, and adult survival data for the Northern Great Plains piping plover, 2014 - 2016
This dataset presents four tabular data files that evaluate the effect of predator exclosures around piping plover (Charadrius melodus) nests on plover nest, chick, within-season, and annual adult survival. During 2014-2016, we designed an experiment to examine nest (n = 418), chick (n = 453), and adult (n = 367) survival at alkaline wetlands of the Northern Great Plains. Alkaline...
