1999-2000 The Marine Operations Committee met monthly over the past year. Overall, our fleet is operating very well. There has been major concern this year with the use of radioisotopes. Difficulties on the upper campus raised regulatory concerns that potentially affected SIO operations. The net result of lengthy and sensitive discussions is that Ms. Sandy Obrien, who has assisted in keeping our isotope operations both safe and legal as an EH & S employee, is now working at Scripps. Thanks to Joris Gieskes and Bob Knox for their role here. Chris de Moustier has lead a successful effort to fund a replacement for the Revelle's Sea Beam, which has not been performing up to expectations. A new SIMRAD multibeam system will be installed in December 2000-January 2001. The new system will be tested as the ship heads south early in the new year. A Hydrographic Doppler Sonar System was installed on the Revelle last fall and brought to life over the course of this year. The system consists of a long range 50 kHz sonar which profiles to 700-1000 m with 15 m depth resolution, and a high resolution 140 kHz device which profiles to 250 m with 4 m resolution. Both ocean velocity and acoustic scattering strength data will be available through the SCG. With the ending of TOGA, WOCE, and several other global research programs there was concern that there would be a shortage of work for our largest ships. In fact, the reverse seems to be the case. Scheduling these ships has been a "challenge". In contrast, our smaller ships have available time in 2001. The excellent management by Dr. Robert Knox, Captain Tom Althouse and Woody Sutherland and their respective teams has made the work of this committee a pleasure. Rob Pinkel, Chair
