A research team including a Scripps Institution of Oceanography at the University of California San Diego climate scientist simulated in a computer model, for the first time, the realistic evolution o...
The Black Sea, a nearly enclosed and isolated environment, has suffered from severe ecological changes during the last three decades. It has been converted from an oligotrophic (less than 100 grams of...
We review the current distribution of lead and lead isotopes in the ocean with regard to the evolving pattern of human emissions during the past decades and centuries.
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Controversy exists about the historic shift of primary producer community structure (PPCS) in Lake Apopka,a shallow, 125-km2lake in central Florida, U.S.A. The controversial questions are: was a lake-...
We used a decadal data set, with weekly to biweekly sampling in April–October and monthly sampling in November– March, to characterize climatic (hurricane-level storms, a sustained 3-yr drought) and ...
We examined the effects of anthropogenic and climatic perturbations on nutrient–phytoplankton interactions and eutrophication in the waters of the largest estuarine systems in the U.S.A., the Chesape...
Utilization of dissolved organic nitrogen (DON) from natural (forests) and anthropogenic (animal pastures, urban/suburban storm water runoff) sources (three sites per source) by estuarine plankton com...
Redfield ratios of remineralization are calculated based on chemical data analysis on isopycnal surfaces. The concentrations of dissolved inorganic carbon used in this study were corrected for the ant...
