Since little is known about deep-water bottom currents on an annual basis, results from current meters may help us interpret genetic estimates of connectivity patterns. Through comparisons of these genetic fingerprints, we will be able to pinpoint which natural populations may have contributed larvae (sources) that are responsible for the growth of Lophelia we observe on the platforms (sinks). For benthic organisms such as corals, connectivity occurs when larvae from one population disperse via ocean currents to another population, where they settle, grow, and reproduce, therefore contributing to the new population and linking the populations through shared genetic makeup. Coral Amendment 9. GOM oil and gas lease blocks Viosca Knoll 826 (VK826, 415–480 m depths) and Viosca Knoll 862/906 (VK862/906, 310–440 m depths) in the north-central GOM, approximately 37 km apart (), were previously reported to exhibit the most extensive DSC accumulations in the GOM (Schroeder and Brooke, 2011).These sites are characterized by L. The orange dots are oil platforms and the orange lines represent pipelines. The single photomosaic at the Viosca Knoll 862 site (VK862) is on a topographic high of exposed carbonate rock. In 1993, Walter made a significant discovery on the block. In addition … NMFS notes that shrimp vessels fishing in Viosca Knoll 862/906 are mainly those fishing for royal red shrimp. 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, but off the bottom, in this area.

Priority areas for HAPC consideration in the northeastern Gulf of Mexico. 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). Another well was directionally drilled, finding nine productive oil and gas sands, totaling 450’ of hydrocarbon pay. The Coelacanth platform is the third-tallest structure of its kind in the Gulf of Mexico—roughly 150 feet taller than the Eiffel Tower. WD 107 is located eight miles seaward of the Southwest Pass of the Mississippi River within a large active mudflow. Leiopathes sp. This map shows the Viosca Knoll area of the Gulf, where the most developed natural Lophelia reefs exist. The Viosca Kr.oll Block Hazard Study has been reviewed by Nr. At this site, the corals had less-calcified, fragile skeletons (“gracilis” morphotype [12]), and there was no hydrocarbon seepage. Contrasting population structure patterns among species indicates that divergent life histories may be the driving force behind population structure (i.e. The well has since yielded over 11 million barrels of oil and 12 bcfg. the head of De Soto Canyon (archived at the US National Museum) and Viosca Knoll. 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. Scattered live L. pertusa thickets grow on large carbonate boulders with abundant anemones, Callogorgia americana delta , bamboo corals (Isididae), antipatharians, and an unidentified species of hexactinellid sponge.

Coral growth on these structures may attract typical Lophelia reef organisms, such as fishes and invertebrates, enhancing biodiversity. Total production of all wells is over 15 million barrels of oil and 15 billion cubic feet of gas. 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). The areas around this proposed HAPC are used to fish for royal red shrimp. SS 332A. The annual rental required by 30 CFR 250.1012 shall continue to be due and payable in December of each calendar year. Contact Us By comparing population structure patterns among different species with divergent life histories within the same habitats, we can draw conclusions about the mechanisms driving dispersal. 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. Option c: “Prohibit bottom tending gear in the Viosca Knoll 862/906 HAPC. There are numerous platforms in close proximity to the VK reefs. Connectivity affects both population structure and genetic diversity, and may play a role in resiliency when faced with human and environmental disturbances. Additional data being collected by the Lophelia II team will help us interpret our results. 8.2) was collected from Viosca Knoll 906/862 (VK-906/862) during Dive 4744 at 307 m depth.

The orange dots are oil platforms and the orange lines represent pipelines. Royal red shrimpers use these areas to pull up nets, but are not trawling directly on the banks. A Rosy Dory, Cyttopsis rosea, on deep coral reefs at Viosca Knoll 862 in the Gulf of Mexico, 9 Oct 2008, ROV photo from Lophelia II project. The orange dots are oil platforms and the orange lines represent pipelines. During the Lophelia I studies, we collected samples from three natural Lophelia sites, Viosca Knoll (VK) 826, VK 862, and Green Canyon. Jack Golden. Shipwrecks and oil platforms in the Gulf may serve as artificial reefs that attract fishes and invertebrates. Download image (jpg, 66 KB). Through comparisons of shared genetic diversity among these sites, we concluded that connectivity appeared high among these sites that spanned about 370 kilometers in the northern Gulf. The Lophelia colonies at the Gulfpenn Wreck site exhibit 4.6 meters (15 feet) of vertical relief along the superstructure. 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. The best development of DSCs in the GOM was previously documented within Viosca Knoll oil and gas lease blocks 826 and 862/906 (north-central GOM) and on the Campeche Bank (southern GOM in Mexican waters). 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. At the time, 2D seismic data wasn't sufficient to define subsurface structure or image amplitude anomalies in an area of mudflow. Sample ID and location for specimens collected between 2003 and 2009 within the Gulf of Mexico from 2 The bacterial communities from VK826 were dominated by a variety of unknown mycoplasmal members of the Tenericutes and Bacteroidetes, whereas the libraries from VK906/862 were dominated by members of the Proteobacteria. In 2008, a non-proprietary 3D survey with better acquisition parameters, allowing for deeper imaging, was purchased. The initial well on block 36 logged 60’ of gas in two Miocene reservoirs. Because connectivity is nearly impossible to directly measure due to the immense space in which tiny larvae have to disperse, sampling organisms from different reefs and indirectly measuring genetic connectivity and population structuring may be the only way to understand how these populations are connected to each other. 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). Prior to Walter’s discovery, several operators had drilled wells on the block, but none had encountered hydrocarbons. Within the Viosca Knoll 862/906 area, the gear deployment prohibitions do not apply to a fishing vessel issued a Gulf royal red shrimp endorsement, as specified in 50 CFR 622.50(c), while fishing for royal red shrimp. One of the sites, VK862-906, is in close proximity to the site reported from the 1950’s field sampling by Moore and Bullis. One of the areas, Viosca Knoll 862/906 is one of the best-studied deep reefs in the Gulf. The deep ocean is often thought of as a vast expanse, devoid of substantial biota save for rare oases (i.e., hydrothermal vents, cold seeps, seamounts, deep water reefs). 3. By Cheryl L. Morrison and Dr. Katharine Coykendall - U.S. Geological Survey, Leetown Science Center. What is the origin and age of the gray basal reef rock containing subfossil L. pertusa and bivalve inclusions? 860, 862, and 905 will be submitted at a later date.

Viosca Knoll 862 was Morakami’s first subsea oil project as well as one of the company’s early horizontal well completions. For Viosca Knoll 862/906, ELB recorded 168 data points and 2 vessels while VMS recorded 8 data points corresponding to 2 bottom longline vessels and 13 data points corresponding to 2 bandit rig vessels. This data showed a more promising anomaly at 20,000 feet, deeper than any existing well had penetrated. What is the age of contemporary, well-developed Viosca Knoll Lophelia reefs, and of individual coral colonies? Installation was completed in Q4 2015, with production start-up slated for mid-2016. Viosca Knoll biotopes available to megafaunal invertebrates and demersal fishes. Collections made during this cruise will be included in our analyses of connectivity among natural and artificial Lophelia reefs in the Gulf. Privacy Policy were Viosca Knoll 862/906 and Viosca Knoll 826. Chapter 3. While several previous wells had been drilled on the block, commercial reserves had not been established. The SS332A platform is located in Ship Shoal Block 332 in the Central Gulf of Mexico (Figure 2). 2. Other members of the team are examining connectivity among octocorals (Andrea Quattrini), black corals (Dannise Ruiz), and brittle stars (Tim Shank and Walter Cho). 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). Website Satisfaction Survey Walter then acquired a proprietary 3D survey that revealed a number of untested amplitude anomalies to the west of the platform. However, in the early 90s, Walter obtained a new survey that utilized advancements in 3D processing and acquisition techniques. For Viosca Knoll 862/906, ELB recorded 168 data points and 2 vessels while VMS recorded 8 data points and 2 bottom longline vessels. Viosca Knoll 862.

This paper documents extensive deep reef ecosystems composed of DSC and rocky hard-bottom recently surveyed on the West Florida Slope (WFS, eastern GOM) during six research … Less than a month later, the Deepwater Horizon caught fire, shutting down all deepwater drilling in the Gulf of Mexico. How the inhabitants of these rare biodiversity hotspots manage to disperse, colonize, and thrive under such seemingly unfavorable conditions is of great interest to many scientists. The new areas are: West Florida Wall, Alabama Alps Reef, L & W Pinnacles and Scamp Reef (combined area), Mississippi Canyon 118, Roughtongue Reef, Viosca Fortunately, Viosca Knoll 906/862 and 826 are listed in the BOEM database of seismic anomalies which means they are protected from drilling and oil infrastructure within 1.24 miles of … This area lacked visible seep megafauna. Given the depth and expense of the well, securing drilling partners to this prospect would be challenging, particularly considering that 2009 was the nadir of the financial crisis. The bacterial communities from VK826 were dominated by a variety of unknown mycoplasmal members of the Tenericutes and Bacteroidetes, whereas the libraries from VK906/862 were dominated by members of the Proteobacteria. Within the proposed Viosca Knoll 862/906 area, the proposed gear deployment prohibitions would not apply to a fishing vessel issued a Gulf royal red shrimp endorsement, as specified in 50 CFR 622.50(c) while fishing for royal red shrimp.
