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...
Scavenging and retention of bismuth by marine plankton and biogenic particles
Scavenging retention bismuth marine plankton biogenic particles
2014/4/17
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 ...

Assessing plankton other particles situ with the SOLOPC
2014/5/16
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...
Composition and degradation of marine particles with different settling velocities in the northwestern Mediterranean Sea
Composition degradation marine particles different settling velocities northwestern Mediterranean Sea
2014/4/22
Settling particles were collected from the Ligurian Sea in the northwestern Mediterranean Sea in May 2003 and separated by elutriation into different settling velocity classes (>230, 115-230, 58-115, ...

Investigation of the optical backscattering scattering ratio of marine particles relation to their biogeochemical composition eastern English Channel and southern North Sea
2014/4/23
The variability of the backscattering to scattering ratio of marine particles, bbp : bp, is examined from in situ measurements performed during the spring and early summer of 2004 in the eastern Engli...
Suspended minerogenic particles in a reservoir: Light-scattering features from individual particle analysis
Suspended minerogenic particles a reservoir Light-scattering features individual particle analysis
2014/4/22
Light-scattering attributes of minerogenic particles in a reservoir, where these particles dominate over a wide range of light-scattering levels, were characterized by an individual particle analysis ...
Direct measurement of diffusivity within diatom aggregates containing transparent exopolymer particles
Direct measurement of diffusivity diatom aggregates transparent exopolymer particles
2014/4/22
We present the first direct measurements of apparent diffusivity within diatom aggregates using a diffusivity microsensor. Transparent exopolymer particles (TEP) and aggregate dry mass (TEP and cells)...

colloidal particles light scattering in the ocean
2014/5/13
We calculated the optical scattering and backscattering coefficients for assemblages of marine colloids from the measured size distribution and the assumed refractive index of colloids. The comparison...
Deposition, benthic residence, and resuspension of fine organic particles in a mountain stream
Deposition benthic residence resuspension fine organic particles mountain stream
2014/5/13
We estimated deposition and resuspension rates of natural particulate organic matter (POM) in Bloomington Creek, Idaho, a mountain stream flowing at 225 L s-1. POM was collected from the water column,...
Attachment to suspended particles may improve foraging and reduce predation risk for tintinnid ciliates
Attachment to suspended particles improve foraging reduce predation risk tintinnid ciliates
