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 ...
HF radars are a unique and powerful tool for measuring surface currents. They provide an unparalleled window into the spatial variations of near-surface currents. But oceanographers who are more accus...
Experience With Shipborne Measurements of Surface Current Fields by HF Radar
Shipborne Measurements Surface Current Fields HF Radar
2015/8/10
Oceanographic research using HF radar techniques started in Germany in 1980 by adopting NOAA's CODAR (Coastal Ocean Dynamics Applications Radar), which has originally been introduced by Barrick et al....
Nearshore and inner shelf dynamics are forced principally by radiation stress gradients induced by shoaling and breaking waves. Waves in shallow water refract due varying bottom topography. Thus the w...
Quantifying Benthic Exchange of Fine Sediment via Continuous,Noninvasive Measurements of Settling Velocity and Bed Erodibility
Fine Sediment Noninvasive Measurements Settling Velocity Bed Erodibility
2015/7/22
Benthic exchange of fine sediment has major implications for the structure and function of shelf and estuarine environments. Globally, the transport of particulate organic carbon from the land to the ...
Understanding Climate Control of Fisheries Recruitment in the Eastern Bering Sea: Long-Term Measurements and Process Studies
Fisheries Recruitment Eastern Bering Sea
2015/7/20
Alaska's Bering Sea ecosystem is changing rapidly, and the people and animals living in this area must quickly adapt. The US National Oceanic and Atmospheric Administration's Ecosystems and Fisheries-...
The Future of SAR-Based Oceanography:High-Resolution Current Measurements by Along-Track Interferometry
SAR-Based Oceanography High-Resolution Current Measurements Along-Track Interferometry
2015/7/16
Since the Seasat mission in 1978, an impressive amount of information on oceanic and atmospheric features over the ocean has been derived from the thousands of images provided by spaceborne synthetic ...

improving the Quality and Accessibility of current profile Measurements in the Southern Ocean
current profile Measurements Southern Ocean
2015/7/15
it takes more
than the Adcp itself, however, to yield good
current measurements. The end result depends
on how and where the sonar is installed; on
the quality of ancillary information includi...
High-Resolution Underway Upper Ocean and Surface Atmospheric Observations in Drake Passage: Synergistic Measurements for Climate Science
Ocean Surface Atmospheric Observations
2015/7/15
This article highlights recent and ongoing studies that analyze in situ underway upper ocean and surface atmospheric observations from frequently repeated transects by the Antarctic Research and Suppl...
Measurements and Models of Heat Flux and Plumes from Hydrothermal Discharges Near the Deep Seafloor
Measurements and Models Heat Flux and Plumes Hydrothermal Discharges Deep Seafloor
2015/7/14
Deep-sea hydrothermal vents are conduits of heat and chemicals from the lithosphere to the hydrosphere. Their plumes rise hundreds of meters from the seafloor into the water column; during their ascen...
The Intergovernmental Oceanographic Commission (IOC) has been involved for 50 years in promoting the close coordination needed to ensure comparability of oceanographic measurements. In particular, IOC...
Applications of Satellite-Derived Ocean Measurements to Tropical Cyclone Intensity Forecasting
Satellite-Derived Ocean Tropical Cyclone Intensity Forecasting
2015/7/6
Sudden tropical cyclone (TC) intensification has been linked with high values of upper ocean heat content contained in mesoscale features, particularly warm ocean eddies, provided that atmospheric con...
