Nanoscale Molecular Composition of Solid Bitumen from the Eagle Ford Group Across a Natural Thermal Maturity Gradient

Mary R Croke, Aaron M Jubb, Justin E Birdwell, Paul C Hackley, Javin J Hatcherian & Jing Qu
Solid bitumen is a petrographically-defined secondary organic matter residue produced during petroleum generation and subsequent oil transformation. The presence of solid bitumen impacts many shale reservoir properties including porosity, permeability, and hydrocarbon generation and storage, amongst others. Furthermore, solid bitumen reflectance is an important parameter for assessing the thermal maturity of formations with little to no vitrinite. While the molecular composition of solid bitumen will strongly impact associated parameters such as the development of organic...

Annual California Sea Otter Census-1985-2014 Spring Census Summary

M. Tim Tinker & Brian B Hatfield
This dataset represents an archived record of annual California sea otter surveys from 1985-2014. Survey procedures involve counting animals during the "spring survey" -- generally beginning in late April or early May and usually ending in late May early June but may extend into early July, depending on weather conditions. Annual surveys are organized by survey year and within each year, three shapefiles are included: census summary of southern sea otter, extra limit counts of...

Bioacoustic manipulation of invasive Bigheaded carp: Common Carp phonotaxis data

Kelsie A Murchy & Marybeth K Brey
This dataset includes the behavioral responses to a broadband sound for common carp in an outdoor concrete pond. Broadband sound (0.06 to 10 kHz) has shown potential as an acoustic deterrent for bigheaded carps, but the response of common carp to broadband sound has not been evaluated. Since common carp are ostariophysians, possessing Weberian ossicles similar to bigheaded carps, it is possible that sound can be used as an acoustical deterrent for all three species.

A website tool for predicting triploidy in larval fish spawns

Jill A Jenkins, Bogdan Chivoiu & Rassa O Dale
This is an online tool called Ploidy Predictor. Triploidy is the condition in which three chromosome sets occur in somatic cells. Triploidization is the most practical, economical, and effective method for mass production of sterile fishes. Some examples include triploid oysters Crassostrea spp., Grass Carp Ctenopharyngodon idella, and Black Carp Mylopharyngodon piceus that are commercially cultured for consumption, weed and snail control, respectively. Triploidization limits the potential for establishment of wild populations. However, treatments used...

Stephen T. Bosse, James G. Flocks & Arnell S Forde
The U.S. Geological Survey Coastal and Marine Geology Program has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic-reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls of continuous profiles up to 25 meters long. As part of the National Geological and Geophysical Data Preservation Program, scientists at the U.S....

Local and landscape-scale data describing patterns of coastal wetland loss in the Texas Chenier Plain, U.S.A.

Camille L. Stagg, Michael J. Osland, Jena Moon, Courtney T. Hall, Laura C. Feher, William R. Jones, Brady Couvillion, Stephen B. Hartley & William Vervaeke
We characterized coastal wetland responses to flooding stress by measuring vegetation cover, wetland elevation and water elevation in healthy and degrading wetlands dominated by Spartina patens. Wetland elevation was measured using real-time kinematic survey methods. Vegetation cover was determined by visual estimation methods, and water elevation was measured using in situ continuous recorders. In addition to these local-scale responses, we also measured landscape-scale patterns of land and water aggregation or fragmentation using remotely sensed data...
