Water-level decline in the Apalachicola River, Florida, from 1954 to 2004, and effects on floodplain habitats
Helen M. Light, Kirk R. Vincent, Melanie R. Darst, Franklin D. Price
2006, Scientific Investigations Report 2006-5173
From 1954 to 2004, water levels declined in the nontidal reach of the Apalachicola River, Florida, as a result of long-term changes in stage-discharge relations. Channel widening and deepening, which occurred throughout much of the river, apparently caused the declines. The period of most rapid channel enlargement began in 1954...

Robert S. Carr, Marion Nipper, Michael Field, James M. Biedenbach
2006, Open-File Report 2006-1147
Toxicity tests are commonly conducted as a measure of the bioavailability of toxic chemicals to biota in an environment. Chemical analyses alone are insufficient to determine whether contaminants pose a threat to biota. Porewater toxicity tests are extremely sensitive to a broad range of contaminants in marine environments and provide...

State-parameter estimation of ecosystem models using a smoothed ensemble Kalman filter
M. Chen, Shuguang Liu, Larry L. Tieszen
2006, Conference Paper, Proceedings of the iEMSs 2006 conference
Much of the effort in data assimilation methods for carbon dynamics analysis has focused on estimating optimal values for either model parameters or state variables. The main weakness of estimating parameter values alone (i.e., without considering state variables) is that all errors from input, output, and model structure are attributed...
