Settling Particles in Aquatic Environments:Low Reynolds Numbers
Settling Particles Aquatic Environments Low Reynolds Numbers
2015/7/23
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...
Carbon Dioxide Pools Discovered in Aegean Sea ’Kallisti Limnes’ Get Their Distinctive Color from Opal Particles
Carbon Dioxide Pools Aegean Sea Kallisti Limnes Distinctive Color Opal Particles
2015/8/4
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...
Measuring the Form of Iron in Hydrothermal Plume Particles
Iron Hydrothermal Plume Particles
2015/7/14
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 ...
Trace metal cycling in the deep water of the South China Sea: The composition, sources, and fluxes of sinking particles
Trace metal cycling in the deep water the South China Sea composition sources fluxes of sinking particles
2014/4/8
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, ...
In situ variability of mass-specific beam attenuation and backscattering of marine particles with respect to particle size, density, and composition
In situ variability mass-specific beam attenuation backscattering marine particles respect to particle size density and composition
2014/4/2
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...

Remineralization upper ocean particles iron biogeochemistry
2014/4/17
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...
Exchange between suspended and sinking particles in the northwest Mediterranean as inferred from the organic composition of in situ pump and sediment trap samples
suspended sinking particles northwest Mediterranean as inferred from the organic
2014/4/16
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...
Spectral variations of light scattering by marine particles in coastal waters, from visible to near infrared
coastal waters light scattering marine particles
2014/4/18
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...
