NOAA Coastal Geospatial Services

The National Oceanic and Atmospheric Administration (NOAA) selected Tetra for a multiple-award, indefinite delivery, indefinite quantity contract to support the Office for Coastal Management’s (OCM) Digital Coast program. Tetra Tech will use innovative collection methods to acquire, analyze, and process geospatial data to address critical coastal issues such as sea level rise, coastal resiliency, sustainable land use, and marine planning. Tetra Tech also will provide technical GIS support services to support green infrastructure development ad creation of sustainable solutions to reduce the impact of rising seas and climate change on coastal shorelines ($49M ceiling over 5 years).

ASPRS UAS Symposium

Tetra Tech Geomatics staff will be attending the ASPRS UAS Mapping Symposium in Palm Springs, CA September 12-14. The symposium will provide participants with opportunities to get up close and in person with the latest in UAS (Unmanned Aerial Systems) technology for professional mapping applications. Our Geomatics team now includes a UAS Operator and we are embracing the new UAS platforms and technology.

Sujoy Roy made a presentation at the Department of Water Resources DSM2 User Group Meeting on “Evaluating Salinity Trends in the Delta Using Data from 1922-2012.”

The location of the low salinity zone in San Francisco Bay where the bottom salinity is 2 parts per thousand (ppt) (termed as X2 and reported as the distance in kilometers from Golden Gate), has been used as the basis for outflow management in the estuary. There is great interest in understanding how the low salinity zone in general, and the X2 position in particular, has changed over time under different conditions of hydrology, exports, and development. This work presents a compilation and analysis of X2 of data over a nine-decade period. Contact Sujoy Roy for additional information.
