Brazos River Estuary water column data from 10-8-00 to 7-30-05.

Samples were collected every quarter from 10-18-00 and are planned to end on 7-30-05. For each sample taken, data is recorded on date, time, location, and weather conditions. 3 stations are sampled each period. 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 loing-term changes in estuary as it relates to changes in freshwater inflow dynamics.
