This provides the first evidence that Rice’s whales occur in Mexican waters.The paper, "Rice's whale occurrence

As well as providing the stunning backdrop for this event, Scripps Institution of Oceanography furnished instruments for the workshop from the large pool of our equipment.GNSS-A and AZA are two independent technologies that are providing scientists with

Glosten, Siemens Energy Select Key Equipment Vendors for World's First Hydrogen-hybrid Research Vessel

selected Ballard Power Systems and Chart Industries as primary equipment vendors for their design of what will be the first hydrogen-hybrid research vessel in the world. The vessel, nominally known as the CCRV, is currently in the design phase and will be owned and operated by UC San Diego’s Scripps Institution of Oceanography (Scripps). Ballard Power Systems will provide the fuel cells which will help power the vessel, and Chart Industries will provide the cryogenic tank and fuel gas system where the liquid hydrogen fuel will be bunkered and conditioned for the fuel cells—both essential

Observation is the first step of the Scientific Method. “What’s that?”, leads to research, hypothesis, and then all the rest that ends in “discovery”. When we can’t send humans to look, we send the robots.Scripps Professor John Issacs developed his first deep sea “Monster Camera” in the 1960’s from surplus WWII aircraft nose cameras. His observations lead him to realize that photographs identify species, while film shows behaviors. It was another Scripps professor, Richard Rosenblatt, who counseled Issacs to look at fish from the lateral side view

of well-wishers watched as FLIP was towed, at sunset, to a dismantling and recycling facility. Last month, a formal good-bye ceremony was hosted by the Marine Physical Laboratory at the University of California, San Diego (UCSD).Still, FLIP — which was owned by the U.S. Navy and managed by Scripps Institution of Oceanography at UCSD — boasts a proud legacy and represents a golden age of oceanography that saw a renewed focus on ocean exploration, the creation of new fields of study, and greater public appreciation of the scientific and strategic importance of the ocean.“Over its

ABS to Class Scripps' New Research Vessel

A hydrogen-fueled research vessel commissioned by the University of California San Diego’s Scripps Institution of Oceanography will be built to ABS Class.Designed by Glosten, the vessel will feature a new hydrogen-hybrid propulsion system that integrates hydrogen fuel cells alongside a conventional diesel-electric power plant, enabling zero-emission operations. The design is scaled so the ship will be able to operate 75% of its missions entirely using hydrogen. For longer missions, extra power will be provided by diesel generators.The 150-foot vessel will be equipped with advanced instruments
