Laguna Madre Estuary water column data on going from 4/27/88.

Samples were collected every quarter from 4-27-1988 and are on going. For each sample taken, data is recorded on date, time, location, and weather conditions. Four stations were sampled. Data measurements at the surface and bottom include water quality (salinity, conductivity, temperature, dissolved oxygen, and pH) nutrients (phosphate, nitrate nitrite, ammonium, and silicate) and chlorophyll a. The purpose of the entire data set is track long-term changes in estuary as it relates to changes in freshwater inflow dynamics.
