Surface Elevation Table Installation Sites Identified: USGS NWRC Branch Chief Tom Doyle and Ecologist Ches Vervaeke worked with U.S. Fish and Wildlife Service Texas Mid-Coast Refuge Complex staff the week of June 24 to help identify appropriate sites to install a network of surface elevation tables (SETs). The SET is a portable mechanical leveling device for measuring the relative elevation change of wetland sediments. SETs will be installed to monitor the effects of sea level rise and estuarine tidal circulation on the refuge. A benchmark pipe is driven into the marsh soil to a depth of 3-6 m and forms the base for the SET. Changes in elevation of the marsh surface relative to the bottom of the benchmark pipe are measured by lowering pins from the SET to the marsh surface. This technique incorporates both surface and subsurface processes occurring between the surface and the bottom of the pipe. The difference in rates between the SET and the marker horizon provides an estimate of the rate of subsurface processes, also called shallow subsidence. (Tom Doyle; Lafayette, La.; 337-266-8647)

Students Learn About STEM Careers and Graduate Level Education: USGS NWRC staff welcomed students participating in the University of Louisiana at Lafayette’s STAGE Program on July 26. Scientists Jim Grace, Jacoby Carter, and Chris Wells provided valuable information about their work and backgrounds. Information Specialist Gabrielle Bodin explained issues associated with Louisiana’s land loss during a tour of the center. STAGE (Smooth Transition for Advancement to Graduate Education) is a mentoring program for underrepresented groups in mathematical sciences in cooperation with Louisiana Historically Black Colleges and Universities (La-HBCUs). It is designed to better prepare students to pursue graduate studies in Science, Technology, Engineering, and Mathematics areas. (Gabrielle Boudreaux Bodin; Lafayette, La.; 337-266-8655)
