The Coal Oil Point seep field - a natural laboratory to test data strategies, evaluate instrumentation performance function, and learn !! Seeps are a major pollution source that stresses humans and the environment. Barbara Channel is the Coal Oil Point seep field about 15 km west of the city of Santa Barbara (Figure 1). “ Compositional changes in natural gas bubble plumes: Observations from the Coal Oil Point marine hydrocarbon seep field,” Geo-Mar. Using 3.5 kHz sonar data, seep distribution offshore of Coal Oil Point was mapped for August 1996, July 1995, and July 1973. If correctly, that implies we were only seeing seep-related hydrocarbons here. Time Evolution Of Beach Tar, Oil Slicks, And Seeps In The Coal Oil Point Seep Field, Santa Barbara Channel, California est documented marine seep field, the Coal Oil Point field (Fig- ure 1), is found along the northern margin of the Santa Barbara Channel in these waters [Ho•,land et al., 1993].

Size-dependent flux distributions, Φ, and vertical velocity functions, VZ(r), were measured with a video bubble measurement system in the Santa Barbara Channel, California. These tarballs are amongst the most plentiful on the beaches around and to the west of Santa Barbara due to proximity to the prolific Coal Oil Point (COP) seep field. The Coal Oil Point seep field offshore from Santa Barbara, California is a petroleum seep area of about three square kilometers adjacent to the Ellwood Oil Field, and releases about 40 tons per day of methane and about 19 tons of reactive organic gas (ethane, propane, butane and higher hydrocarbons), about twice the hydrocarbon air pollution released by all the cars and trucks in the county in 1990. 1. May 25, 2015 update: Comments from Alex Greene: 0276-0460 23, 187– 193.). Range of values is 100,000 to 200,000 m3/day. Model results are therefore reported as relative particle densities rather than oil concentrations. CREATIVE The seep field lies in shallow waters due to the same geological process (faults and other tectonic motions) that created the Santa Ynez coastal Mountain range and the deep Santa Barbara Channel. The ocean floor near here is a rich natural petroleum seep field, which gives Coal Oil Point its name. These seeps were observed by the earliest Spanish settlers and English explorers [ll'ilkinxon, 1972]. The fate of marine seep gases (transport to the atmosphere or dissolution, and either bacterial oxidation or diffusion to the atmosphere) is intimately connected with bubble and bubble-plume processes, which are strongly size-dependent. The Coal Oil Point area is home to seeps that release on the order of 100 barrels ... beached in the near-field. Concentrations of these gases were analyzed in the surface water down-current of the seep field over a 15-month period.
