Internal Wave-Driven Surface Currents From HF Radar
Internal Wave-Driven Surface Currents HF Radar
<
2015/8/10
Surface current observations from high-frequency (HF) radar have revealed that not only are the low-frequency and tidal currents resolved by the measurement, higher-frequency motions are also containe...
Two important aspects of tidal currents are (1) their temporal coherence and (2) their constancy (over centuries). The first rigorous evaluation of an Ocean Surface Current Radar (OSCR) system exploit...
There are thousands of deepwater sites in the Gulf of Mexico
where persistent natural hydrocarbon seepage contributes
to the formation of authigenic carbonate hardgrounds on a
seafloor dominated...
Larval Transport and Coastal Upwelling: An Application of HF Radar in Ecological Research

For many marine fish and invertebrate species, near-surface currents strongly affect the likelihood of surviving as a planktonic larva and arriving at a suitable location, say, a rocky coastline, a ke...

Nearly all target detection "radars" in existence operate at microwave frequencies because their wavelengths are small enough that compact antennas provide both good angular resolution and high sensit...
Transport Patterns of Tropical Reef Fish Larvae by Spin-Off Eddies in the Straits of Florida

Tropical reef fishes belong to a broad phylogenetic group and, as a result, exhibit considerable diversity. Their only shared characteristic as an ecological entity is their fate as reef-associated ad...
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...
The directional spectrum S(k) [or S(f,θ)] measures the distribution of wave energy in wave number, k, (or frequency, f) and direction. Different contributions to local wave energy, e.g., swell from di...
Shipboard Deployment of a VHF OSCR System for Measuring Offshore Currents

In July 1994, an OSCR unit was deployed aboard the R/V Columbus Iselin to explore the feasibility of obtaining offshore, vector surface currents from a single platform. The concept is straightforward....

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....
Exploration of the Windward Passage and Jamaica Channel: Tectonic Gateways to the Caribbean Sea
Windward Passage Jamaica Channel

In August 2014, E/V Nautilus explored the region delimited
by two deep straits of the northern Caribbean: the Windward
Passage, which separates Cuba and Haiti, and the Jamaica
Channel, which sep...
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...
Besides the measurement of ocean surface currents, high-frequency (HF) radar has also been demonstrated to be effective at measuring the wind direction at scales on the order of one to several kilomet...
