THERE IS A NEED FOR DEVELOPMENT OF A COMMERCIALLY AVAILABLE ECONOMICAL ACOUSTIC DOPPLER BACKSCATTER INSTRUMENT WHICH CANBE EASILY DEPLOYED AND USED TO SIMULTANEOUSLY ACQUIRE CURRENT PROFILE DATA AND BACKSCATTER AMPLITUDE INFORMATION RELATING TO PARTICLE CONCENTRATIONS IN THE WATER COLUMN. THE RESEARCH PROPOSED IN PHASE I IS DIRECTED AT TWO AREAS OFDOPPLER BACKSCATTER MEASUREMENT WHERE ADVANCES IN ...

WHEN IT IS NECESSARY TO RAISE A MARINE PIPELINE FOR REPAIR DUE TO TRAWLER SNAG, ETC., THE PIPELINE WILL BUCKLE, AND THEN THE BUCKLE WILL PROPAGATE IF ALL CONDITIONS ARE NOT PROPER. WITH SEVERE BUCKLES, THE PIPE WILL BREAK OPEN ALLOWING THE OIL TO SPILL. THIS CAN BE MINIMIZED BY PERIODICALLY PLACING REMOTELY OPERABLE VALVES IN THE LINE FOR CUTOFF. BUT SOMETIMES THE PIPELINE ROTATES AS IT IS BEING L ...

USING RADIO TELEMETRY MODEMS, IS CURRENTLY POSSIBLE. THIS IS NECESSARY BECAUSE LACK OF MONITORING CAUSES INADEQUATE CONTROL OF INTERNAL CORROSION TAKING PLACE INSIDE OFFSHORE PIPELINE SYSTEMS. THE NET RESULT IS PIPELINE FAILURE DUE TOTHE EFFECTS OF CORROSION. THE RESULT OF PIPELINE FAILURE WILL BE AN OIL SPILL IN COASTAL WATERS. AS THE NATION'S OFFSHORE PIPELINE SYSTEM GROWS OLDER, THE NET EFFECTS ...
