The purpose of this activity is to familiarize students with how a particle's size, shape and orientation affects its settling at low Reynolds numbers. This activity can also be used to teach statisti...
The location of the second largest volcanic eruption in human history, the waters off Greece’s Santorini are the site of newly discovered opalescent pools forming at 250 meters depth. The interconnect...
The global mid-ocean ridge (MOR) system is a 60,000 km submarine volcanic mountain range that crosses all of the major ocean basins on Earth. Along the MOR, subseafloor seawater circulation exchanges ...
Moored sediment traps were deployed for 1 yr at depths of 120, 600, and 3500 m in the water column to investigate the trace metal (M) (Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) composition, sources, ...
This study analyzes relationships between concentration of suspended particles represented by dry mass,[SPM], or area, [AC], and optical properties including particulate beam attenuation (cp), side sc...
We did radiotracer experiments using207 Bi to quantify the bioavailability, accumulation, and retention of bismuth in marine plankton and biogenic detritus. The accumulation of207Bi by two species of ...
The role of heterotrophic bacteria in iron recycling, the influence of complexation on iron remineralization,and iron mobilization rates from lithogenic vs. biogenic particulate iron (PFe) were examin...
The extent to which sinking particles disaggregate and exchange with surrounding material affects the efficiency of particulate organic carbon export to the deep sea. In 2003 and 2005, we compared th...
Field measurements and Mie calculations of the particulate light-scattering coefficient (bp, in m21 ) in the nearinfrared and visible spectral domains are combined to quantify and model the effect of...
The role of suspended minerogenic particles in light scattering in eastern Lake Superior and Keweenaw Bay (11 sites) during July of 2006 was evaluated with an individual particle analysis technique (...
The isotope composition of zinc (Zn) was determined in settling particles collected monthly over a year in the hypolimnion of the eutrophic Lake Greifen (Switzerland) in order to explore the potentia...
The dispersion of heavy suspensions in a wave boundary layer over a nonerodible bed is examined theoretically. Focusing attention on the horizontal variation of the ambient wave pattern, an effective ...
The authors present a theory on the transport and resuspension of fine particles in a tidal boundary layer when the ambient tidal flow is nonuniform due to a peninsula along the coastline. As a first ...
We combined a Sounding Oceanographic Lagrangian Observer float with a Laser Optical Plankton Counter (LOPC) and a fluorometer to make an autonomous biological profiler, the SOLOPC. The instrument sens...
This study looks at the behavior of fluid particles/parcels that move along isopycnic surfaces. The aim is to show that the diffusive process of mixing by eddies causes such particles to move toward r...
