Coral growth on these structures may attract typical Lophelia reef organisms, such as fishes and invertebrates, enhancing biodiversity. The dominant taxa at both the VK862 and VK906 sites, in terms of numbers and biomass, are anemones. The company’s engineering team creatively leveraged their talents to become a leading operator of subsea completed fields. Viosca Knoll Block 862, SS005 to Viosca Knoll Block 817, Platform A Offshore, Louisiana, OCS Federal Waters, GOM Ms. Gobert: In accordance with 30 CFR, Part 250.1008(c), Walter Oil & Gas Corporation respectfully requests a “Temporary Cessation of Pipeline Operations” for the above referenced pipeline until May 13, 2020. If platforms occur in appropriate locations and depths, they may increase connectivity among natural reefs, potentially adding resilience to the Gulf Lophelia community in the face of future environmental change or disturbance. Sample ID and location for specimens collected between 2003 and 2009 within the Gulf of Mexico from 2 At this site, the corals had less-calcified, fragile skeletons (“gracilis” morphotype [ 12 ]), and there was no hydrocarbon seepage. (k) Viosca Knoll 862/906 HAPC. Station Viosca Knoll 906/862 (VK906/862) was at a depth horizon of 315 m and contained many small isolated colonies of Lophelia . A map of the areas and associated coordinates can be found here. Establish Viosca Knoll 862/906 as a habitat area of particular concern with regulations prohibiting fishing with bottom tending gear, but allow royal red shrimp fisherman to keep their nets in the water in this area. For Viosca Knoll 862/906, ELB recorded 168 data points and 2 vessels while VMS recorded 8 data points and 2 bottom longline vessels. There were indications of deeper potential, but the data was poorly resolved. Establishes Viosca Knoll 862/906 as a habitat area of particular concern with regulations prohibiting fishing with bottom-tending gear, but allows royal red shrimp fisherman to keep their nets in the water, but off the bottom, in this area. Chapter 3. An interesting aspect of the platform populations is the known age of the structures, which sets a maximum age boundary on the corals as well. What is the age of contemporary, well-developed Viosca Knoll Lophelia reefs, and of individual coral colonies? Molecular analysis of bacterial diversity showed a marked difference between the two study sites, Viosca Knoll 906/862 (VK906/862) and Viosca Knoll 826 (VK826). Viosca Knoll 906/862 (VK906/862) was at a depth horizon of 315 m and con-tained many small isolated colonies of Lophelia (13). One of the sites, VK862-906, is in close proximity to the site reported from the 1950’s field sampling by Moore and Bullis. Gaseous emissions at the dock site 1n Venice. Non-proprietary 2-D seismic data revealed strong amplitude anomalies nearby, prompting the drilling of a second well into the adjacent block 37, which yielded a total of 170’ of gas. NMFS notes that shrimp vessels fishing in Viosca Knoll 862/906 are mainly those fishing for royal red shrimp. While several previous wells had been drilled on the block, commercial reserves had not been established. Contact Us were Viosca Knoll 862/906 and Viosca Knoll 826. 8.2) was collected from Viosca Knoll 906/862 (VK-906/862) during Dive 4744 at 307 m depth. Source: Steve W. Ross / USGS DISCOVRE Expedition Gulf of Mexico. Since corals require hard substrate, such as rocks, to settle and grow, reef formation may be limited by space availability. Natural cold seep sites greater than 1,000 meters depth are shown in green. This data showed a more promising anomaly at 20,000 feet, deeper than any existing well had penetrated. Although encountering an oil zone, the well was deemed marginally economic. Interestingly, the accumulation was missed by less than 200’ by wells drilled by Humble Oil in 1968 and by McMoran in 1983. There are relatively few bioherms (i.e., coral-built mounds) in the northern GOM, and most DSCs are attached to existing hard substrata (e.g., authigenically formed carbonate). The orange dots are oil platforms and the orange lines represent pipelines.

Report an Error, Site Index NMFS notes that shrimp vessels fishing in Viosca Knoll 862/906 are mainly those fishing for royal red shrimp. the head of De Soto Canyon (archived at the US National Museum) and Viosca Knoll. While several previous wells had been drilled on the block, commercial reserves had not been established. Until recently, benthic habitats dominated by deep-sea corals (DSC) appeared to be less extensive on the slope of the Gulf of Mexico (GOM) than in the northeast Atlantic Ocean or off the southeastern US. This map shows the Viosca Knoll area of the Gulf, where the most developed natural Lophelia reefs exist. Website Satisfaction Survey Therefore, one of our primary research objectives in the Lophelia II project is to assess patterns of population connectivity among natural and potential artificial reefs in the Gulf of Mexico. We are also examining connectivity patterns in the squat lobster, Eumunida picta, which is a common inhabitant of Lophelia reefs. Site Info, Office of Ocean Exploration and Research Additional data being collected by the Lophelia II team will help us interpret our results. Within the current Pulley Ridge HAPC, establish a new HAPC with fishing regulations prohibiting all fishing with bottom tending gear, except for long line gear.
