Effect of future CO2 and temperature regimes on phytoplankton community composition, biomass and photosynthetic rates in the western English Channel
… of up to 14-fold. Light-saturated photosynthetic carbon fixation rates increased > 6-fold under elevated pCO2 while an increase of up to 3-fold resulted from elevated temperature. The combined effects of elevated pCO2 and temperature reduced biomass in late summer and had no effects on biomass in …

Headwater stream network connectivity: biogeochemical consequences and carbon fate
… of river network length and regulate cycling of carbon and oxygen as they expand and contract their connections across the landscape. Though headwater streams integrate many biogeochemical signals from the watersheds they drain and provide important ecosystem services, their diverse habitats and …

Organic Carbon Cycling in East China Sea Shelf Sediments: Linkages with Hypoxia
… of sediment and terrestrial derived organic carbon (OC) to the Changjiang large delta-front estuary (LDE) in the East China Sea (ECS). This study analyzed bulk OC, biomarkers including lignin and plant pigment, black carbon (BC) on ECS sediments sampled in winter 2009 and 2010 in order to …

Microbial Degradability of Terrigenous, Marsh-Exported, and Estuarine Colored Dissolved Organic Matter in Long Island Sound
… waters as well as an important part of the carbon cycle and serves as a primary food source for aquatic food webs. Additionally, the colored portion of DOM (CDOM) impacts coastal optical properties, ocean color, and light attenuation. High levels of CDOM have been shown to inhibit the growth …
