Assessing pelagic and benthic metabolism using free water measurements

Automated in situ sensors for measuring changes in dissolved oxygen (DO) at high frequency have facilitated estimates of gross primary production (GPP) and respiration (R) in aquatic systems. Lake researchers usually rely on a single sensor for these estimates, but such point measurements may miss important spatial heterogeneity in within-lake processes and may not accurately represent systemwi...

Effects of macroalgal mats on sediment nutrient release and benthic-pelagic coupling

Nutrient loading, one of the most severe human impacts on coastal bays, leads to a range of ecological effects including the decline of seagrass beds and proliferation of macroalgal mats as well as other changes in nutrient cycling, oxygen levels and habitat quality. Here, I examined the effects of the presence of macroalgal mats on fine-scale nutrient and oxygen dynamics and benthic-pelagic co...

Benthic community responses to pulses in pelagic food supply: North Pacific Subtropical Gyre

Time-series measurements of particulate organic carbon (POC) and particulate nitrogen (PN) fluxes, sediment community composition, and sediment community oxygen consumption (SCOC) were made at the Hawaii Ocean Time-series station (Sta. ALOHA, 4730m depth) between December 1997 and January 1999. POC and PN fluxes, estimated from sediment trap collections made at 4000m depth (730m above bottom), ...

Benthic-pelagic links and rocky intertidal communities: bottom-up effects on top-down control?

Insight into the dependence of benthic communities on biological and physical processes in nearshore pelagic environments, long considered a "black box," has eluded ecologists. In rocky intertidal communities at Oregon coastal sites 80 km apart, differences in abundance of sessile invertebrates, herbivores, carnivores, and macrophytes in the low zone were not readily explained by local scale di...
