Subtropical snook gather at a warm Florida springhead in winter
Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.

Flight area for Trans-Pecos aeromagnetic and radiometric survey
Map indicating flight area for Trans-Pecos aeromagnetic and radiometric survey. The survey area includes parts of El Paso and Hudspeth counties, Texas, and Otero County, New Mexico. Flights will begin in November 2020 and are expected to conclude in mid-January 2021.

Austin Chalk Core
Bedding features in the core from the USGS Gulf Coast #4 Bonham borehole, in the Eagle Ford Group mudstones from a depth of about 401 feet, Fannin County, Texas. The Eagle Ford Group lies underneath the Austin Chalk and serves as the source rock for much of the Austin Chalk's petroleum.

Requirements for the Contracted-Opening Method
This video discusses the general requirements that will be needed to accomplish a contracted-opening indirect discharge measurement. Approach section, contracted section, and necessary high-water mark locations are described along with scenarios where the method will not be successful.

Habitat Connectivity: Assessing Threats and IDing Conservation Actions
An important conservation strategy for climate change is to enhance and maintain regional habitat connectivity for the long-term viability of wildlife populations. Modeling habitat connectivity for wildlife species often results in a mapped network of linkages between habitat patches.

Waterfowl Seeking Submerged Aquatic Vegetation
Waterfowl populations in the northern Gulf of Mexico (NGOM) rely extensively on plants that grow under the surface in shallow waters, know as submerged aquatic vegetation (SAV), as a critical food resource in the winter season.
