Data

The U.S. Geological Survey has compiled information on water withdrawal and use for Puerto Rico at 5-year intervals since 1980 to provide data for the management of the Commonwealth’s water resources. For 2015, water withdrawals and use were estimated for 78 municipalities from fresh groundwater and surface water in the categories of public use, domestic use, irrigation use, livestock...

This dataset is one of several collected as part of the Bureau of Ocean Energy Management (BOEM)-funded California Deepwater Investigations and Groundtruthing (Cal DIG I) project. The purpose of the study is to assess shallow geohazards, benthic habitats, and thereby the potential for alternative energy infrastructure (namely floating wind turbines) offshore south-central California due...

This data release contains the boundaries of conventional assessment units for the assessment of undiscovered oil and gas resources in the Eastern Mediterranean Area. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total...

Data for 819 pan concentrated stream-sediment samples, nonmagnetic heavy-mineral concentrate (HMC) samples, and chemical data for 93 of HMC samples. The samples were collected in 2004-2008 as part of a reconnaissance geochemical geological survey of drainage basins mostly in the Taylor Mountains 1:250,000-scale quadrangle in southwestern Alaska. Samples were collected from first- or...

Birds (Clark's grebe, Aechmophorus clarkii; Forster's Tern, Sterna forsteri), fish (Peacock bass, Cichla temensis, Cichla monoculus; Pescada, Plagioscion squamosissimus) and earthworms were analyzed for selenium, total mercury, and methyl mercury concentration and mercury speciation. A Clark's grebe was collected from Lake Berryessa (California, United States) in September 2012. A...

This data set provides capture information and body size measurements of adult and gosling Greater White-fronted Geese captured at three study sites on the Arctic Coastal Plain of Alaska, 2012-2014.

This dataset includes 15-minute interval data on stream temperature, stage, and discharge from an upstream and downstream gaging location on West Twin Creek, a first-order tributary to Nome Creek in the White Mountains of Alaska.

These data include stream water chemistry from headwater streams to large rivers across three national parks in Arctic Alaska: Bering Land Bridge National Preserve, Kobuk Valley National Park, and Noatak National Preserve.

This R script will run one replicate of one scenario used by Weiser (2021) to quantify biases in estimates of nest survival when nests are not found at the beginning of the nesting interval (age 0). The script simulates nest monitoring histories based on input parameters, applies models with or without an age effect to estimate daily survival rates, and calculates nest survival (to the...

Trace-metal concentrations in sediment and in the clam Limecola petalum (World Register of Marine Species, 2020; formerly reported as Macoma balthica and M. petalum), clam reproductive activity, and benthic macroinvertebrate community structure were investigated in a mudflat located 1 kilometer south of the discharge of the Palo Alto Regional Water Quality Control Plant (PARWQCP) in...
