QUANTIFIED MARINE OIL EMISSIONS WITH A VIDEO-MONITORED, OIL SEEP-TENT

Identifying and quantifying sources of oil and seabed emissions are the first steps in assessing the need for and desirability of various mitigation strategies. This paper presents a new technique for quantifying seabed emissions--a diver deployed, video-monitored oil seep-tent that provided both real time and high time resolution monitoring of oil emissions, allowing assessment of variability. The oil capture tent was developed and deployed during two field trips to quantify oil emissions from several sites in nearshore waters off Summerland Beach in Santa Barbara County, California, at a water depth of about 5 m. The tent was a tall, inverted polyvinyl chloride plastic cone, which funneled oil into a video-observed sample collection jar. Sample jars were periodically retrieved and analyzed to determine oil and gas emissions at two seeps not associated with physical structures, and a suspected abandoned oil well, designated S-3. Video analysis, calibrated with collected and analyzed oil samples allowed a detailed time series of emission rates to be determined for investigation of sources of variability. Oil emission variations with a periodicity comparable to the swell were observed, as was a strong response at 120 seconds.
