U.S.-Built NSF Research Icebreaker Begins Operation The nation's first commercial icebreaking research ship, the Nathaniel B. Palmer, recently be- gan operation for the National Sci- ence Foundation (NSF) U.S. Ant- arctic Program. To be operated under the direc- tion of Antarctic Support Associates (ASA), a joint venture of Holmes & Narver, Services, Inc. (HNSI), Or- ange, Calif., and EG&G, Inc., Wellesley, Mass., the Nathaniel B. Palmer was developed for the ex- press purpose of supporting research in Antarctica. NSF has commis- sioned the ship under a long-term lease with Edison Chouest Offshore, Galliano, La., whose subsidiary, North American Shipbuilding, built the vessel. The Palmer has been under con- struction for the past two years at Larose, La., from where she recently departed for sea trials in the Gulf of ENVIROVAC sewage systems solve all your marine sanitation needs.

Following her debut cer- emonies in Port Fourchon, La., she departed for the Antarctic via Punta Arenas, Chile. The unique vessel is designed to traverse the polar seas for a multi- tude of research projects, transport- ing scientists to remote ice-locked locales in Antarctica and allowing them to conduct varied scientific activities on board. Under the supervision of ASA support personnel, the Palmer's maiden assignment will involve ro- tation of scientists from a mile long ice floe where the first Russian- American ice station was launched in mid-February in Antarctica's Weddell Sea. The project is gather- ing vital data on global climate and ocean currents that are key to deter- mining the effects of global warming. To break through ice three feet thick, the Palmer uses a control- lable-pitch thruster that will acti- vate the ship's 13,000-hp main en- gines. Unusual for an icebreaker, the 308-1/2-foot Palmer can navigate rough open seas, rolling less than 8 degrees in 16-foot waves and can accommodate 37 scientists in out- door temperatures that reach -50 degrees F. Operational cruises may last for three months and cover 15,000 miles. The vessel carries several acous- tical systems, including equipment for seismic recording, echo sound- ing and acoustic navigation and a Doppler speed log capable of cur- rent profiling at up to 400-meter water depth. A helicopter hangar and a flight deck also are on board. USCG Sponsors Industry Day, May 8, In New Orleans The Eighth Coast Guard District is sponsoring a 1992 Industry Day and luncheon at the Doubletree Hotel New Orleans. A general ses- sion and six small group sessions will be held to discuss such topics as: "Licensing"; "Drug Testing"; "OPA 90"; "User Fees"; "Inspections"; "Outer Continental Shelf'; "Water- ways Management"; and "Facility and Vapor Recovery" issues. The $32 cost of the affair will include a banquet-style lunch, snacks and handouts. For applications and to suggest specific topics for discussion, con- tact Lt. Comdr. Ken Parris at (504) 589-6271.
