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 ...
MISST:The Multi-Sensor Improved Sea Surface Temperature Project
MISST Multi-Sensor Sea Surface Temperature Project
2015/7/3
Sea surface temperature (SST) measurements are vital to global weather prediction, climate change studies, fisheries management, and a wide range of other applications. Measurements are taken by sever...
The German-Indonesian Tsunami Early Warning System (GITEWS) aims at reducing the risks posed by events such as the 26 December 2004 Indian Ocean tsunami. To minimize the lead time for tsunami alerts, ...
Salt Fingers Observed in the Mediterranean Outflow Region (34°N, 11°W) Using a Towed Sensor
Mediterranean Outflow Region Towed Sensor Salt Fingers
2009/3/7
A towed microstructure instrument has been used to measure small-scale conductivity fluctuations in a quasi-horizontal plane, as well as local vertical gradients of temperature and conductivity. This ...
Sensor Response Mismatches and Lag Correction Techniques for Temperature-Salinity Profilers
Sensor Response Temperature-Salinity Profilers Lag Correction Techniques
2009/2/18
Salinity-temperature-depth profilers measure temperature. directly but infer salinity from measurements of temperature, pressure and conductivity. Errors may therefore be introduced into the salinity ...
Matching Temperature and Conductivity Sensor Response Characteristics
Matching Temperature Conductivity Sensor Response Characteristics
2009/1/16
A method to match the response of the SBE-3 temperature sensor and the SBE-4 conductivity cell is described. The technique uses a recursive filter in the time domain, which allows direct calculation o...
Fast direction of arrival algorithm based on vector-sensor arrays using wideband sources
acoustic vector sensor propagator method coherent processing fast algorithm
2011/9/14
An acoustic vector sensor (AVS) can capture more information than a conventional acoustic pressure sensor (APS). As a result, more output channels are required when multiple AVS are formed into arrays...
Optical fiber based slide tactile sensor for underwater robots
underwater robot manipulator tactile sensor optical fiber
2011/9/14
In the underwater environment,many visual sensors don’t work,and many sensors which work well for robots working in space or on land can not be used underwater.Therefore,an optical fiber slide tactile...
Microscale mineralization pathways in surface sediments: A chemical sensor study in Lake Baikal
Microscale mineralization pathways surface sediments A chemical sensor study Lake Baikal
2014/5/4
We used an array of ion-selective electrodes (oxygen [O2], hydrogen [H+], carbonate [CO32-], calcium [Ca2+], ammonium [NH4+], and nitrate [NO3-]) with a micromanipulator to study mineralization proces...
