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...
Multichannel seismic imaging of ocean water column features is a new interdisciplinary study that may become an accepted oceanographic tool in coming years. We now know that reflectors are associated ...
REMOTE SENSING DATA ASSIMILATION IN WATER QUALITY NUMERICAL MODELS FOR SIMULATION OF WATER COLUMN TEMPERATURE
data assimilation numerical model water temperature
2015/1/16
Numerical models are important tools for simulating processes within complex natural systems, such as hydrodynamics and water quality processes within a water body. From decision makers’ perspectives,...
Assimilating water column and satellite data for marine export production estimation
Assimilating water column satellite data marine export production estimation
2014/12/12
Recent advances in satellite retrieval methodology now allow for estimation of particular organic carbon (POC) concentration in ocean surface waters directly from satellite-based optical data. Because...
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...
Accessing the Potential of Satellite and Telemetric Data to Evaluate the Influence of the Heat Flux Exchange in the Water Column Mixing and Stratification
Thermal Infrared Heat and Cooling Mixing Stratification
2013/3/11
The objective of this work is to evaluate the feasibility of moderate resolution satellite data estimating the surface heat balance in a tropical hydroelectric reservoir. Each component of the heat fl...
Hypoxia and nitrogen processing in the Baltic Sea water column
Hypoxia nitrogen processing Baltic Sea water column
2014/4/4
Steep redoxclines form between oxic surface water and the stagnant, sulfidic hypolimnion in the eutrophied,
brackish water Baltic Sea. Nitrification, denitrification, and anammox were measured at and...
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...
Increase in water column denitrification during the last deglaciation: the influence of oxygen demand in the eastern equatorial Pacific
water column denitrification the last deglaciation oxygen demand the eastern equatorial Pacific
2010/1/21
Here we present organic export production and nitrogen isotope results spanning the last 30 000 years from a core recovered off Costa Rica (Ocean Drilling Program (ODP) Site 1242) on the leading edge ...
