Web10 apr. 2024 · Multibeam was introduced outside of military applications in the 1970s with the application of multibeam to seep science in the oil and gas industry, and the use of ultrashort baseline-positioned cores in a real-time geographical information system (GIS) to target seeps, began in the late 1990s, with the first proprietary survey in 2000. WebTo examine effects of natural hydrocarbon seepage on health of deep-water octocorals, we have examined the effects of proximity to seepage on the abundance and diversity of 13 morphospecies associated with the octocoral Callogorgia delta. Our preliminary analysis indicates that the abundance of catshark eggs is higher and ophiuroids is lower on non …

Energy-rich … WebMarine seeps introduce significant amounts of hydrocarbons into oceans and create unusual habitats for microfauna and -flora. In the vicinity of chronic seeps, microbes likely exert control on carbon quality entering the marine food chain and, in turn, hydrocarbons could influence microbial community composition and diversity.
Web1995). At hydrocarbon seeps, chemosynthetic substrates are generated as by-products of microbial consumption of hydrocarbons in the upper few meters of the sediment column.
