MODFLOW-NWT model for risk-based decision-support groundwater modeling for the lower San Antonio River Basin, Texas, USA MODFLOW-NWT model for risk-based decision-support groundwater modeling for the lower San Antonio River Basin, Texas, USA

A MODFLOW-NWT groundwater/surface-water model was developed to evaluate the responses of low-flow conditions and groundwater levels within the lower San Antonio River Basin, Texas, USA under conditions of reduced recharge and increased groundwater withdrawals. There was concern that decreased recharge and increased groundwater withdrawals may adversely affect streamflow and groundwater...

Point Sampling Data for Eelgrass (Zostera marina) and Seaweed Distribution and Abundance in Bays Adjacent to the Togiak National Wildlife Refuge, Alaska, 2008-2010 Point Sampling Data for Eelgrass (Zostera marina) and Seaweed Distribution and Abundance in Bays Adjacent to the Togiak National Wildlife Refuge, Alaska, 2008-2010

These data are in six tables relating to surveys of eelgrass beds in three bays adjacent to Togiak National Wildlife Refuge, in southwestern Alaska. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass.

Thin section images of drill core from the Chrome Lake area in the Stillwater Complex, Montana Thin section images of drill core from the Chrome Lake area in the Stillwater Complex, Montana

This dataset includes photographic images of thin sections of drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the drill holes. The core was drilled in order to study contact-type copper and nickel sulfide mineralization in the Stillwater Complex. The images of the entire thin section, both in plane- and cross-polarized light, were...
