Increasing trends of coral mortality is a challenge to coral reef management worldwide, and a need exists to identify the causes and pathways involved. Pathology is useful to help decipher potential causes of mortality in animals, because it illuminates agents associated with lesions and gives insights on the nature of how a host responds to said agents. To better understand the nature...

Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...

Sagebrush songbird fledglings (Brewer's sparrow, sagebrush sparrow, and sage thrasher) were measured and tracked using radio telemetry in Pinedale, Wyoming during 2021-2023.

This data release is composed of several datasets that contain water, sediment, and rock chemistry results from samples collected within and near the Florida River watershed in southern Colorado. Samples were collected during three sampling events in April 2022, May 2022, and August–September 2022. The data will aid investigators in understanding the sources and seasonality of aluminum...

This data release presents model inputs and outputs to support an investigation of occurrence and temporal changes of imidacloprid from the U.S. Geological Survey National Water Quality Network spanning 77 sites between 2013 and 2022. Imidacloprid is a neonicotinoid insecticide used to control a wide range of agricultural and non-agricultural insect pests. The Seasonal Wave and...

In 2005, a silvicultural restoration study was implemented to observe the response of individual red spruce to various percent basal area (BA; m2) removal treatments of competing hardwood species. These treatments consisted of four different basal area removals: control was 0 percent, low was about 33 percent, medium was about 67 percent, and high was about 100 percent around individual...

We provide new 10Be/26Al cosmogenic surface exposure ages for two samples collected from gravel terraces along the Rio Grande. Each sample consisted of approximately 6 milky quartz pebbles ranging in diameter from 3 to 5 cm collected from the surface of a pristine, unmodified middle Pleistocene terrace tread adjacent to fluvially scoured basaltic bedrock. Chemical isolation of aluminum...

This dataset contains water quality data collected in the Mississippi Sound before (pre) and after (post) barrier island restoration of Cat and Ship Island, Mississippi. The barrier island restoration included sand placement which has the potential to alter water quality conditions within the Mississippi Sound estuary. Therefore, water quality monitoring was conducted at five...

The U.S. Geological Survey (USGS) has compiled the Energy Geochemistry Database (EGDB), containing 3,619,149 analytical results for 111,791 samples collected by the Energy Resources Program (ERP) to develop an understanding of the physical and geochemical processes responsible for hydrocarbon formation. It also serves as a tool to assess oil and gas potential for sedimentary basins in...

This dataset consists of one table containing whole-rock geochemistry data for 926 rocks from eastern, central, and southwestern interior Alaska, plus analytical results for concurrently analyzed geochemical standard materials. All materials in the present study were analyzed by ALS Global between 2014 and 2025 using a range of different techniques, so multiple unique entries for a given...

These datasets provide age-model codes and resultant paleoearthquake age distributions for three paleoseismic sites along the southern San Andreas Fault. The code format is compatible with the age-model program OxCal (Bronk Ramsey 2009) which calibrates radiocarbon dates to calendar years and uses stratigraphic relationships among radiocarbon samples and sedimentary units to compute

In the San Luis Obispo Bay area of central California, interpretations of marine terrace ages have been hampered by inconsistent results from geochronological indicators (U-series ages of corals and correlations using amino acid racemization of mollusks) and seemingly contradictory paleozoogeographic aspects of fossil faunal assemblages. The two lowest-elevation terraces are Q1 (lower)...
