This data set documents the dry mass energy density, distribution, and stomach contents of age-0 chum salmon (Oncorhynchus keta) captured in the Kuskokwim Bay estuary in May and June 2004. The analysis of this data was published in Burrill et al. 2018 (DOI :10.1007/s00300-018-2297-2.).

This dataset provides information on fish species composition and their diet information for 16 lakes and 16 ponds at two locations on the central Arctic Coastal Plain, Alaska. In one table, we provide the presence of fish species and the total species count for each lake or pond sampled. This table also includes metrics of surface water connectivity to the stream network. In a second table, stomach content information is provided for fish collected during summer sampling periods (late June to mid-August) over three years (2011–2013). The third table includes stable carbon isotope and stable nitrogen isotope signature data for fish species and snails (the baseline organism) from 16 water bodies at one study location...

This data release contains information on the seasonal diversity and abundance of arthropods collected at the Colville River Delta, Alaska, 2011-2012 and 2014-2107. Researchers with the US Geological Survey began studying the reproductive ecology of birds at a site on the Colville River near the Beaufort Sea coast in 2011. Researchers concurrently collected arthropods at 3-day intervals to understand the relationship between the seasonal abundance of arthropods and the reproductive output of insectivorous birds.

This set of data files are the appendices for paper titled Transgressive-regressive cycles in the metalliferous, oil shale-bearing Heath Formation (Upper Mississippian), central Montana. The dataset consists of 8 appendices, including a histogram of solid bitumen and vitrinite Ro values, gas chromatograms, isotopic data, organic and inorganic geochemical analyses, and x-ray diffraction mineralogy data.

This dataset contains results from a stratigraphic section of the Hue Shale located along the Jago River in the Arctic National Wildlife Refuge at 69.9099, -143.3947 (WGS84). Sample heights were measured with a tape measure in a continuous succession. Zircon grains from volcanic ashes were analyzed via laser ablation at either the University of California, Santa Barbara (UCSB) or the University of Arizona Laserchron Center (ALC) using a Photon Machines Analyte 193-nm Excimer laser and Nu Instruments Plasma HR MC-ICPMS. Zircon grains from volcanic ashes were analyzed via chemical abrasion at the Berkeley Geochronology Center using a Sector 54 TIMS. Bulk mudstone samples were subject to a variety of analyses.
