New Sensor Technology for In Situ Measurements of Ocean Chemistry
New Sensor Technology Situ Measurements Ocean Chemistry
2015/8/14
Chemical processes in the ocean and at its interfaces with the atmosphere and the seafloor play a major role in regulating global biogeochemical cycles. Predicting the impact of human disturbances on ...
Ocean-observing systems are changing the way ocean science is accomplished. No longer is ocean science limited to observations made by ships, whose scheduling and expense often constrain research to s...
Thalassia testudinum phosphate uptake kinetics at low in situ concentrations using a 33 P radioisotope technique
Thalassia testudinum phosphate uptake situ concentrations
2014/4/23
A new 33
P-tracer technique was used to define low-level phosphate (Pi) uptake kinetics for a dominant tropical
seagrass, Thalassia testudinum. We established seagrass Pi uptake kinetics at hi...
The role of hydrodynamics in structuring in situ ammonium uptake within a submerged macrophyte community
nutrients water fl ow patchiness Cymodocea nodosa Caulerpa prolifera
2014/4/1
In low-nutrient, macrophyte-dominated coastal zones, benthic ammonium (NH4
+
) uptake may be influenced by the structural properties of plant canopies via their effect on near-bed hydrodynamic...
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...
Methyl mercury dynamics in a tidal wetland quantified using in situ optical measurements
Methyl mercury dynamics a tidal wetland quantified in situ optical measurements
2014/4/8
We assessed monomethylmercury (MeHg) dynamics in a tidal wetland over three seasons using a novel method that employs a combination of in situ optical measurements as concentration proxies. MeHg conce...
In situ diel cycles of photosynthesis and calcification in hermatypic corals
In situ diel cycles photosynthesis calcification hermatypic corals
2014/4/17
Diel cycles of photosynthesis, respiration, and calcification were studied in situ on two hermatypic corals,Acropora eurystomaandFavia favus, using a submerged respirometer deployed at 5-m depth in th...
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...
In situ measurements of turbulence in fish shoals
situ measurements turbulence fish shoals
2014/4/16
Turbulence was measured in situ within shoals of juvenile perchPerca fluviatiliswith a self-contained autonomous microstructure profiler near an artificial reef in Lake Constance, Germany. Depth-avera...
Simultaneous determination of in situ vertical transitions of color, pore-water metals, and visualization of infaunal activity in marine sediments
Simultaneous situ vertical transitions of color
2014/4/17
The vertical color transition from brown to gray-green in marine sediments is linked to the Fe redox boundary
and is commonly used as a proxy for biogeochemical state. We combine time-lapse sediment ...
Spectra of Internal Waves：In-Situ Measurements in a Multiple-Layered Structure
Internal Waves Multiple-Layered Structure In-Situ Measurements
2009/4/3
The persistence of layering between 200 and 400 m depth in the Arctic Ocean has enabled construction of accurate internal wave amplitude traces from a 30-hr series of successive temperature profiles t...
Some Aspects of Gulf Stream Western Boundary Eddies from Satellite and In Situ Data
Gulf Stream Western Boundary Eddies Satellite In Situ Data
2009/2/19
NOAA-5 infrared images were used to determine statistics of existing and developing perturbations on the western boundary of the Gulf Stream. The satellite data were combined with oceanographic data t...
