Forcing and Dynamics of Seafloor-Water Column Exchange on a Broad Continental Shelf
Forcing and Dynamics Seafloor-Water Column Exchange Broad Continental Shelf
2015/7/22
Relict sediments of elevated permeability characterize the majority of continental shelves globally (Emery, 1968). In these settings, interactions between benthic boundary layer (BBL) flows and seabed...
Visually striking faunal communities of high abundance and biomass cluster around hydrothermal vents, but these animals don't spend all of their lives on the seafloor. Instead, they spend a portion of...
Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets
Estimating Zooplankton Biomass Water Column Near Endeavour Segment Juan de Fuca Ridge Acoustic Backscatter Concurrently Towed Nets
2015/7/14
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate...
The total radiant energy, and the average depth of all the photons, in the water column
The total radiant energy the average depth all the photons in the water column
2014/4/2
Using radiative transfer theory I show that for a given waveband, the total radiant energy,Qt, present within the water column (per square meter of surface) is proportional to the scalar irradiance ju...
Anaerobic ammonium oxidation (anammox) bacteria and sulfide-dependent denitrifiers coexist in the water column of a meromictic south-alpine lake
Anaerobic ammonium oxidation bacteria sulfide-dependent denitrifiers coexist in the water column a meromictic south-alpine lake
2014/4/2
In addition to organotrophic denitrification, alternative pathways, such as anaerobic ammonium oxidation(anammox) or sulfide-dependent denitrification may be important modes for the removal of fixed n...
Metaproteomic characterization of dissolved organic matter in the water column of the South China Sea
Metaproteomic characterization dissolved organic matter water column South China Sea
2014/4/4
We characterized dissolved organic matter (DOM; < 0.7 μm in size) collected from the surface (10-m and 75-m) and bathypelagic (3000-m) layers in the South China Sea using the shotgun proteomic approac...
Characterization of particulate organic matter in the water column of the South China Sea using a shotgun proteomic approach
Characterization of particulate organic matter water column of the South China Sea shotgun proteomic approach
2014/4/17
We characterized particulate organic matter (POM) collected from both the surface (41 m and 200 m) and mesopelagic layers (500 m and 1000 m) in the western South China Sea. By using a shotgun proteomi...
Aquatic metabolism in the Everglades: Dominance of water column heterotrophy
water column heterotrophy Aquatic metabolism
2014/4/16
Using high-frequency measurements of free water dissolved oxygen (O2), we assessed gross primary production
(GPP), respiration (R), and net aquatic production (NAP) in the shallow-water Everglades pe...
Influence of water-column depth and mixing on phytoplankton biomass, community composition, and nutrients
Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...
An expression is derived for the surface salt input needed to induce complete convective overturning of a polar water column consisting of 1) a layer of sea ice, 2) a freezing temperature mixed layer,...

We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separateand combined effec...
The optical volume scattering function: Temporal and vertical variability in the water column off the New Jersey coast
scattering function Temporal
2014/5/13
I present optical data collected offshore of the New Jersey coast at the Long Term Ecological Observatory LEO-
15 during the summer of 2001. The data were collected by using a LISST-100 instrument, w...
Benthic algae control sediment–water column fluxes of organic and inorganic nitrogen compounds in a temperate lagoon
Benthic algae control sediment– water column fluxes organic and inorganic nitrogen compounds temperate lagoon
2014/5/22
Coastal lagoons are a common land-margin feature worldwide and function as an important filter for nutrients entering from the watershed. The shallow nature of lagoons leads to dominance by benthic au...
New aspects of migratory behavior of phytoplankton in stratified waters: Effects of halocline strength and light on Tetraselmis sp. (Prasinophyceae) in an artificial water column
migratory behavior phytoplankton stratified waters halocline strength light on Tetraselmis an artificial water column
2014/5/20
There is very little information in the literature about how phytoplankton flagellates respond to rapid changes in salinity (e.g., haloclines of different strength). Here we present such data obtained...
Acetate cycling in the water column of the Cariaco Basin: Seasonal and vertical variability and implication for carbon cycling
Acetate cycling in the water column Cariaco Basin Seasonal and vertical variability carbon cycling
2014/5/27
Acetate oxidation frequently has been used as proxy of organic carbon decomposition in marine anoxic sediments. However, the importance of acetate uptake in carbon cycling in marine anoxic water colum...
