There was a dramatic decrease in cold-water plankton during the 20th century, in contrast to thousands of years of stability, according to a National Science Foundation-funded study by ...
The sea is Earth's most formidable carbon dioxide storage machine, but mysteries abound about the interlocking processes and the myriad organisms involved.Now, thanks to NSF-funded research published ...
Natural and man-made inland waters represent globally significant sites of methane production and emit annually about 100 Tg of this potent GHG to the atmosphere. On the other hand, a large fraction o...
Large, robust, lens-shaped microfossils from the approximately 3.4 billion-year-old Kromberg Formation of the Kaapvaal craton in eastern South Africa are not only among the oldest elaborate microorgan...
When Victor Hensen deployed the first true plankton net in 1887, he and his colleagues were attempting to answer three fundamental questions: What planktonic organisms are present in the ocean? How ma...
It is difficult to describe the properties of a microorganism without first cultivating it. There has been a great deal of effort and considerable success in predicting microbial metabolic activities ...
During the lifetime of the National Science Foundation's Coastal Ocean Processes program, four experiments were conducted on the US West Coast in the northern California Current System. Although each ...
Single-celled eukaryotes called protists are vitally important to marine ecosystems. Protists with chloroplasts (algae) carry out most of the primary production in the sea. What feeds on this algal pr...
Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar "greening" event--a massive bloom of microscopic plants, or phytoplankton--unfolds each spring in the North ...
A wide variety of different plankton system models have been coupled with ocean circulation models, with the aim of understanding and predicting aspects of environmental change. However, an ability to...
The ongoing, anthropogenically-driven changes to the global ocean are expected to have significant consequences for plankton ecosystems in the future. Because of the role that plankton play in the oce...
We introduce a trait-based description of diatom functional diversity to an existing plankton functional type (PFT) model, implemented for the eutrophied coastal ecosystem in the Southern Bight of th...
We measured net planktonic community production (NCP), community respiration (CR), and gross primary production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
We introduce a trait-based description of diatom functional diversity to an existing plankton functional type (PFT) model, implemented for the eutrophied coastal ecosystem in the Southern Bight of the...
A mesocosm experiment was performed to evaluate the species-dependent effects of crustacean plankton on the microbial community in Lake Taihu, a large shallow eutrophic lake in China. Four dominant sp...
