Bitumen Reflectance Data from the Tattoo Well in the Horn River Basin, Sample E200205 Bitumen Reflectance Data from the Tattoo Well in the Horn River Basin, Sample E200205

Bitumen reflectance data from a sample collected from the vertical EOG TATTOO D129 A28-F/094-O-10 ("Tattoo") well in the Horn River Basin, as part of the collection of a high-resolution geochemical data set.

Testing reproducibility of vitrinite and solid bitumen reflectance measurements in North American unconventional petroleum systems (2019) Testing reproducibility of vitrinite and solid bitumen reflectance measurements in North American unconventional petroleum systems (2019)

To test reproducibility of vitrinite and solid bitumen reflectance measurements in mudrocks, an interlaboratory study (ILS) was conducted using six samples from United States unconventional petroleum systems. Samples selected from the Marcellus, Haynesville, Eagle Ford, Barnett, Bakken and Woodford are representative of resource plays currently under exploitation in North America. All...

Point clouds, bathymetric maps, and orthoimagery generated from overlapping lakebed images acquired with the SQUID-5 system near Dollar Point, Lake Tahoe, CA, March 2021 Point clouds, bathymetric maps, and orthoimagery generated from overlapping lakebed images acquired with the SQUID-5 system near Dollar Point, Lake Tahoe, CA, March 2021

Underwater images were collected in Lake Tahoe, CA, using a recently developed towed-surface vehicle with multiple downward-looking underwater cameras. The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). The data were collected March 10th and 11th of 2021 to assess the accuracy, precision, and effectiveness of the new...

Global Catalog of Calibrated Earthquake Locations Global Catalog of Calibrated Earthquake Locations

We produced a globally distributed catalog of earthquakes and nuclear explosions with calibrated hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations or GCCEL. This dataset currently contains more than 18,000 events in about 250 clusters distributed around the world. Also included are more than 2.7M arrival times observed at more than 18,000 stations. The...

Electron Probe Microanalyses of apatite, rutile, and titanite from stream sediment and rock samples in the eastern Tanacross quadrangle, eastern Alaska Electron Probe Microanalyses of apatite, rutile, and titanite from stream sediment and rock samples in the eastern Tanacross quadrangle, eastern Alaska

The exploration for porphyry deposits in some parts of Alaska may require unconventional exploration geochemical methods, depending on type of cover. The Taurus deposit and others in the region are mostly concealed by residual soils that in part include ash and loess, and therefore traditional stream sediment samples typically contain subdued geochemical signatures. Indicator mineral...

Nutrient Addition Experiment in the Sacramento River Deep Water Ship Channel Nutrient Addition Experiment in the Sacramento River Deep Water Ship Channel

Data were collected in the Sacramento River Deep Water Ship Channel (West Sacramento, CA) in support of a whole-ecosystem experiment investigating whether phytoplankton production and biomass would respond to nitrate additions, which could potentially be exported to food-limited regions in the Sacramento-San Joaquin Delta. The experiment was conducted from July 2 to September 18, 2019.
