Abstract:

Contains data on water quality from monthly transects in Lake Pontchartrain and Barataria estuary. Includes analyses of dissolved nutrients (nitrate, nitrite, phosphate, silicate), total phosphorus, total nitrogen, suspended sediments, dissolved organic carbon, temperature, salinity, secchi disk depth, and phytoplankton pigments. There is a variable list with units for both Barataria (BT) and Lake Pontchartrain (LP) data sets, including station locations.

Purpose:

This is a post-spill collection of data. It was collected to compare before spill water quality and to track any changes that might indicate restoration of water quality.
