Cosmogenic 10Be and 26Al Surface Exposure Data and Ages for Middle Pleistocene Terrace Deposits Along the Rio Grande, Sunshine Valley Sub-Basin, Southern San Luis Basin, Costilla County, New Mexico Cosmogenic 10Be and 26Al Surface Exposure Data and Ages for Middle Pleistocene Terrace Deposits Along the Rio Grande, Sunshine Valley Sub-Basin, Southern San Luis Basin, Costilla County, New Mexico
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...
Long-term water quality data in the Mississippi Sound from 2014-2024 Long-term water quality data in the Mississippi Sound from 2014-2024
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...
Relative abundance of Clostridium botulinum type E toxin gene in sediment cores collected from northern Lake Michigan near Sleeping Bear Dunes National Lakeshore, USA Relative abundance of Clostridium botulinum type E toxin gene in sediment cores collected from northern Lake Michigan near Sleeping Bear Dunes National Lakeshore, USA
This data release contains relative abundance data of the Clostridium botulinum neurotoxin type E gene (bontE) in sediment cores collected from three nearshore depositional basins near Sleeping Bear Dunes National Lakeshore (SLBE), Lake Michigan, in September 2010. Sediment cores were collected using a box corer and maximum collection depth ranged from 23 to 42 centimeters. Each sediment...
Energy Geochemistry Database Energy Geochemistry Database
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...
Whole Rock Major and Trace Element Chemistry for Igneous, Sedimentary, and Metamorphic Rocks from Eastern to Southwest Interior Alaska Whole Rock Major and Trace Element Chemistry for Igneous, Sedimentary, and Metamorphic Rocks from Eastern to Southwest Interior Alaska
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...
Age-model codes and paleoearthquake ages for the Frazier Mountain, Pallett Creek, and Wrightwood paleoseismic sites along the Southern San Andreas Fault, California Age-model codes and paleoearthquake ages for the Frazier Mountain, Pallett Creek, and Wrightwood paleoseismic sites along the Southern San Andreas Fault, California
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
