Coupling air–water CO2 flux and primary production dynamics under hydrologic variability in a large urban estuary

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Estuaries are critical for land‐ocean carbon exchange, but coupling mechanisms between air–sea CO2 fluxes (FCO2) and phytoplankton gross primary productivity (GPP) remain poorly understood. This study used high‐frequency underway monitoring in the Lingdingyang Estuary to resolve spatiotemporal interplays between FCO2 and GPP.

Typhoon‐induced surface chlorophyll a decline on the shelf of the South China Sea

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract By disturbing the upper ocean, typhoons may play a crucial role in marine ecosystems. Previous studies mostly demonstrated surface chlorophyll a (Chl a) increase under typhoon conditions. By using satellite data and a physical–biogeochemical model, however, we show that approximately 49% of typhoons crossing the northern shelf of the South ...

Spatial mapping of dissolved methane using an in situ sensor in Puget Sound

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Release of methane, as gas bubbles or in the dissolved phase, from the seafloor has been observed in coastal waters (< 200 m) and deep ocean basins (> 1000 m). Methane dissolution within the water column affects the geochemistry of the surrounding water, leading to localized oxygen loss and potential escape to the atmosphere, particularly from

Continuous determination of dissolved inorganic carbon fluxes from pumping suspension feeders

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Suspension‐feeding organisms play a pivotal role in the cycling of carbon in the oceans. They filter large amounts of water, filter out organic matter, remineralize it, and release respiratory CO2 back into the water column. Measuring emissions of respiratory CO2 in situ from suspension feeders poses the challenge of detecting small changes in
