Cable System. Antilles Crossing is a 940 km undersea fiber optic cable system linking St. Lucia, Barbados, and St. Croix. Antilles Crossing will provide communications to the rest of the world. Both the Barbados and

St. Lucia landings are being conduct- ed by the Cable Ship Teneo. After the shore-end landing in Barbados is complete, the Teneo will head north to complete the shore-end segment in

St. Croix followed by the final splice.

Installation of the transmission equipment at the Viggie Beach, St.

Lucia cable station, as well as at the

Needhams Point, Barbados and

Hamms Bay, St. Croix cable stations, is complete. Tyco

Telecommunications expects to have the system up and running - connect- ing Barbados, St. Lucia, and St. Croix to the rest of the world, by June.

Scripps Research

Oceanographer Receives

Munk Award

Peter Worcester, a research oceanog- rapher at Scripps Institution of

Oceanography at the University of

California, San Diego, has been selected as winner of the Walter

Munk Award for Distinguished

Research in Oceanography Related to

Sound and the Sea.

The award is granted jointly by The

Oceanography Society, the Office of

Naval Research (ONR) and the

Office of the Oceanographer of the

Navy. Worcester is being recognized for his "early and continuing contri- butions to the development of acoustical oceanography and tomo- graphic inverse methods for acoustic measurement of ocean processes, for tireless service aimed at developing a responsible permitting structure for the use of sound in the sea for scien- tific purposes and for leadership in the U.S. ocean acoustics communi- ty."

Teledyne RDI Wins NDBC

Contract

Teledyne RD Instruments has been awarded a contract from the National

Data Buoy Center (NDBC) to sup- ply 27 Workhorse Acoustic Doppler

Current Profilers (ADCPs) to sup- port numerous NDBC platforms.

The 27 Workhorse ADCPs will be delivered in four product configura- tions ranging from 75 to 1200 kHz, which will allow for profiling in water depths ranging from 5 to 400 m.

The ADCPs will be deployed for one- year durations, mounted on buoys,

C-MAN stations and seafloor plat- forms. The units will provide a cur- rent profile ensemble on an hourly basis, delivering near real-time accu- rate current data for a variety of

NDBC programs.

Teledyne RD Instrument's

Workhorse ADCPs measure current flow and direction at up to 128 verti- cal data points (bins) in the water col- umn, providing a clear illustration of the current dynamics over an extend- ed range. The Workhorse ADCPs incorporate patented Broadband technology that allows the instru- ment to efficiently collect an increased number of data ensembles over an extended period of time. The

Workhorse ADCPs also incorporate a unique four-beam configuration that provides data QA/QC, thus ensuring the integrity of collected data.

ACMA Concludes

NOAA Job

Alan C. McClure Associates (ACMA) has concluded its assign- ment of assisting in the design and development of a new Small

Waterplane Area Twin Hull (SWATH) coastal mapping vessel (CMV) for the National Oceanic and

Atmospheric Administration (NOAA). "The vessel's primary mission will be to conduct full seafloor mapping of U.S. coastal areas," said Doug

Ottens, principal marine engineer with ACMA. "The vessel's unique design and capabilities will enable it to monitor discreet changes in coastal area floors which, in turn, will allow for enhanced monitoring by the gov- ernment and supplement to national security efforts."

ACMA's scope of work included intact and damage stability to CFR subchapter 'U' requirements. Marine engineering activities included pow- ering and maneuvering predictions, as well as propeller design, shaft alignment calculations and general piping systems and electrical load analysis. Structural FEA models were developed to determine the vessel's global strength, verify minimum scantlings and calculate lightship weight. ACMA also planned, super- vised and provided customer over- sight during model tank testing to verify the vessels final performance characteristics. people & companies
