1987. The Scripps Institution of Oceanography developed an approximately $100,000 water tunnel treadmill for studying the swimming dynamics and physiology of large, fast-swimming marine fish. The portable treadmill was a closed recirculating water system in plastic pipes mounted on a 5-by-6-meter wooden pallet. ... University of Houston researchers achieved superconductivity at 98° Kelvin by using liquid nitrogen rather than the standard coolant, liquid helium. ... Det Norske Veritas led a project to establish a basis for safely implementing fiber optics in maritime, offshore and subsea use.

1997. The U.S. Mineral Management Service held a record-breaking sale of offshore oil and natural gas leases in the central Gulf of Mexico, attracting $824 million in high bids from 81 companies. ... Scientists from the National Center for Atmospheric Research published a study arguing that microwave sounder unit (MSU) temperature data were poorly suited for gauging long-term surface trends. They said frequent replacement of satellites might produce spurious temperature drops that mask a rise in readings. ... Nautronix Ltd. delivered two digital helium speech unscrambler systems to the Norwegian Underwater Technology Center A/S for an upgrade to its hyperbaric lifeboat reception facility.

2002. Delmar Systems Inc. and Shell Exploration & Production Co. reached a world-record depth for moored vessels. The Deepwater Nautilus was moored in 8,009 feet of water in the Gulf of Mexico. ... The University of California, Santa Cruz, launched the Network for Environmental Observation of the Coastal Ocean (NEOCO), which sent real-time data from seven sites along the California coast to a database, to study coastal ecosystems and global warming. ...
