    Observations of multipath on the western shelf area of the Florida Straits have consistently revealed an intense arrival associated with refracted bottom reflected (RBR) rays/modes. The ‘late’ or ‘focused’ arrival is 15 to 20 dB higher than other arrivals. Within the Straits of Florida, a strongly sheared western boundary current interacts with waves and wind to produce a complex environment that is difficult to forecast, and makes in situ data collection at the ocean surface challenging.

    On the northern side of the Strait are Spain and Gibraltar (a British overseas territory in the Iberian Peninsula), while on the southern side are Morocco and Ceuta (a Spanish autonomous city in northern Africa). Its boundaries were known in antiquity as the Pillars of Hercules.. Due to its location, the Strait is commonly used for illegal immigration from Africa to Europe. Florida Current Salinity and Salinity Transport: Straits of Florida at 27°N (Figure 1). The hydrographic and velocity data sets are averaged into a composite, referred to as – or into –, to reduce synoptic variability and to focus on low-frequency patterns.

      Passive Gulf of Mexico Loop Current Observations from HF Radar Across the Yucatan Strait This project will procure, install, and operate high frequency radar systems to measure surface currents at two locations in the Yucatan Channel region of . The West Florida Continental Shelf (WFS) is broad and gently sloping with its m isobath situated some km offshore. The WFS circulation, driven by tides, winds, and buoyancy fluxes, is also influenced by the Gulf of Mexico Loop Current (LC) that enters through the Yucatan Strait and exits as the Gulf Stream though the Straits of Florida.

address this deficiency. Direct velocity observations were col- lected using a hull-mounted ADCP along a number of sections across the passages of IAS, in eastern Caribbean Sea, and in the Straits of Florida (Figure 1).

Herein, the ADCP velocity data from these cruises are used to examine the velocity structure in the upper m of the. A recent hydrographic survey of the Florida Current at 27°N revealed an enhanced upward flux of nutrients along the Florida coast.

Geostrophic flow of the Gulf Stream through the narrow Florida. The western boundary current (i.e., the Gulf Stream) originates in the vicinity of the Straits of Florida. Warm water in the Caribbean is transported rapidly northward through the eastern Gulf of Mexico and the Straits of Florida and along the east coast of North America (Loder et al.,Figure 1).

The maximum speeds of tidal current for the rest of the points are about knots to knots. Conclusion Although the technology of surface current observation with HF-radar is not yet established, hopefully in the near future we be able to make widespread and timely observations under all.

To our knowledge the measurements described here represent the first long-term records of the current and water mass structure ever collected in the strait.

Decreasing depth and width in the straits cause current speeds to increase from the gulf to °N where the Bahamas Banks end abruptly and the current widens and becomes the Gulf Stream (Richardson et al.

The Florida Current has been measured for many years in the Florida Straits using a variety of observing systems, including ship sections, moorings, and submarine cables. Retired telecommunications cables across the straits (e.g., Larsen and Sanford ) measure the electric field induced by the motion of salt ions through the Earth’s.

We conducted hydrographic observations 23 times across the TKS from to from the training vessels (T/Vs) Tenyo-maru and Koyo-maru of the National Fisheries University, T/Vs Kakuyo-maru and Nagasaki-maru of Nagasaki University, and the research vessel (R/V) Tansei-maru of the Japan Agency for Marine-Earth Science and Technology ().We set up six stations in the eastern.

One of the first documented observations of large-amplitude tidal velocity fluctuations in the Florida Straits goes back to the works of J. Pillsbury in the late years of the 19th century.

He found that approximately twice a day the surface velocity changes for as much as 1 knot ( ms -1) in some regions of the Florida Straits. Support of National Science Foundation GA and GA with Nova University is acknowledged for support of this work.
