The Carbon:234 Thorium ratios of sinking particles in the California Current Ecosystem 2: Examination of a thorium sorption, desorption, and particle transport model
Thorium-234 (234 Th) is a powerful tracer of particle dynamics and the biological pump in the surface ocean; however, variability in carbon:thorium ratios of sinking particles adds substantial uncertainty to estimates of organic carbon...
Zooplankton play an important role in global biogeochemistry, and their secondary production supports valuable fisheries of the world's oceans. Currently, zooplankton standing stocks cannot be estimated using remote sensing techniques....
Oceanographic field programs often use delta N-15 biogeochemical measurements and in situ rate measurements to investigate nitrogen cycling and planktonic ecosystem structure. However, integrative modeling approaches capable of...
We investigated variability in the C:234Th ratio of sinking particles and its relationship to changing water column characteristics and plankton ecological dynamics during 29 Lagrangian experiments conducted on six cruises of the...
Largely due to size differences, mesozooplankton are important exporters of carbon and prey for larger organisms, while microzooplankton are important recyclers of nutrients, dominant grazers of phytoplankton, and a key link in the...
A multimethod process-oriented investigation of diverse productivity measures in the California Current Ecosystem (CCE) Long-Term Ecological Research study region, a complex physical environment, is presented. Seven multiday deployments...
Lagrangian Studies Of Net Community Production: The Effect Of Diel And Multiday Nonsteady State Factors And Vertical Fluxes On O-2/ar In A Dynamic Upwelling Region
The ratio of dissolved oxygen to argon in seawater is frequently employed to estimate rates of net community production (NCP) in the oceanic mixed layer. The in situ O-2/Ar-based method accounts for many physical factors that influence...
In marine ecosystems, many planktonic organisms precipitate biogenic silica (bSiO(2)) to build silicified skeletons. Among them, giant siliceous rhizarians (>500 mu m), including Radiolaria and Phaeodaria, are important contributors to...
