LPBF announces the release of Hydrocoast maps for the week of February 25th to March 3rd!!!!
The Hydrocoast program collects a number of environmentally dynamic datasets in an effort to monitor the condition (salinity component) of the basin’s estuaries. Wind, rain, tides and freshwater influx from streams and diversions are variables that cause salinity fluctuation, and play a vital role in the health of the basin’s estuaries. The Hydrocoast program monitors these variables over a seven day period and produces bi-monthly map products showing the movement of water and salinity across the basin (using field data, MODIS, sattelite imagery, precipitation data, wind data and permanent monitoring stations in the basin such as USGS buoys, Coastwide Reference Monitoring System (CRMS), etc.). As a tool, these map products can be used for scientific discussion, restoration planning between state and federal agencies, and by the commercial and recreational fishery community.

The Hydrocoast maps for the week of February 25th to March 3rd show a trend of overall freshening of the basin resulting from significant rainfall for this period. Cumulatively, 2 to 8-inches of rainfall was recorded within the Basin this period. Weekly stream discharge increased in the Pearl River (270,510 to 390,336 cfs), Tangipahoa (10,839 to 20,080 cfs), Tickfaw (3,781 to 11,134 cfs) and Amite (22,280 to 56,039 cfs) as a result of rainfall. The weekly Caernarvon and MGP discharge decreased (14,270 to 12,420 cfs and 14,226 to 9,592 cfs, respectively) and is attributed to lowering river stage, but still affected the isohaline gradient. The resultant winds for this period were out of the southeast with oscillating velocities of 2 to 14 m/s (4.5 to 31 miles/hr).
