Researchers at the Scripps Institution of Oceanography and Jacobs School of Engineering at the University of California, San Diego and their colleagues have designed 3D printed, coral-inspir...
Alison Sweeney of the University of Pennsylvania has been studying giant clams since she was a postdoctoral fellow at the University of California, Santa Barbara. These large mollusks, which anchor th...
There’s an ancient group of algae that evolved in the world’s oceans before our backboned ancestors crawled onto land. They are so numerous that their gigantic blooms can affect the weather, and they ...
Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
Bromoform (CHBr3; 11–486 fmol L−1 h−1), dibromomethane (CH2Br2; 0–9.4 fmol L−1 h−1), and low amounts of chloride-substituted chlorobromomethanes were produced from southern Cal...
Heterotrophic production and abundance of prokaryotes (i.e.,BacteriaandArchaea) in meso- (200–1000 m) and bathypelagic (.1000 m) zones were measured at 31 stations along meridional transects of the ce...
The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll concentrations in which new production is generally considered to be supported by upward fluxes of nitrate from the dee...
Hydrogen peroxide (H2O2 ) plays key roles in aquatic systems, including metal redox cycling and degradation of organic matter into bioavailable forms. Abiotic photoproduction, via photo-oxidation of...
Bromoform (CHBr3; 11–486 fmol L−1 h−1), dibromomethane (CH2Br2; 0–9.4 fmol L−1 h−1), and low amounts of chloride-substituted chlorobromomethanes were produced from southern Cal...
Dissolved inorganic carbon (DIC), total alkalinity (TAlk), pH, and dissolved oxygen (DO) were determined in the Mississippi River plume during five cruises conducted in the spring, summer, and fall. I...
We experimentally investigated the response of phytoplankton and understory macroalgae to canopies of giant kelp, Macrocystis pyrifera, by following changes in their biomass and net primary productio...
Herein we present the results of a series of laboratory experiments conducted to delineate the relationship between dissolved organic phosphorus (DOP) utilization and organic matter production by the ...
The whole metazoan community inhabiting macrophyte stands and gravel beds of the English chalk stream River Lambourn were sampled for 1 yr. Secondary production estimates for specific taxa of macrofau...
We investigated productivity at the basal trophic level in 15 unproductive lakes in a gradient ranging from clear-water to brown-water (humic) lakes in northern Sweden. Primary production and bacteria...
