For Viosca Knoll 862/906, ELB recorded 168 data points and 2 vessels while VMS recorded 8 data points and 2 bottom longline vessels. NMFS notes that shrimp vessels fishing in Viosca Knoll 862/906 are mainly those fishing for royal red shrimp. The platform was designed to: accommodate future tie-backs from the flextrend and deepwater, and. Viosca Knoll 862. The platform serves as a junction platform for EPN's Viosca Knoll Gathering System and hosts a Taurus 60 driven gas compressor and a slug catcher for the Ram Powell gas pipeline. Prior to Walter’s discovery, several operators had drilled wells on the block, but none had encountered hydrocarbons. Disclaimer This map shows the Viosca Knoll area of the Gulf, where the most developed natural Lophelia reefs exist. 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). 860, 862, and 905 will be submitted at a later date. 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. Characterization of Viosca Knoll Biotopes Sulak et al. Report an Error, Site Index There are numerous platforms in close proximity to the VK reefs. Viosca Knoll 862 was Walter’s first subsea oil project as well as one of the company’s early horizontal well completions. Coral growth on these structures may attract typical Lophelia reef organisms, such as fishes and invertebrates, enhancing biodiversity. mobile vs sessile, lecithotrophic vs planktotrophic larvae) whereas similar population structure patterns among species within the same habitat may indicate that physical forces such as prevailing currents, temperature, and/or pressure regimes may be influencing the recruitment and settlement of all inhabitants in kind. 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). Summary: Video clip of a Rosy Dory in about 500 metres off the Canary Islands. The result should be a much more comprehensive picture of connectivity patterns and should allow assessment of the ecological importance of artificial reefs to the longevity of natural populations. 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. Additional data being collected by the Lophelia II team will help us interpret our results. In 1993, Walter made a significant discovery on the block. The platform processes production from EPN's VK817 field and from the Walter Oil & Gas deepwater field in Viosca Knoll Block 862. These two areas, if the boundaries are kept as the working group presented would significantly affect the royal red shrimp fishery. 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. In 1989, Walter farmed in and discovered the South Marsh Island 36/37 Field. In 2008, a non-proprietary 3D survey with better acquisition parameters, allowing for deeper imaging, was purchased. The known age of the structures also allows for growth rate studies.

(k) Viosca Knoll 862/906 HAPC. Given that these structures often sit well above the sea floor, corals that settle on them may benefit from strong, nutrient-rich currents that deliver food and remove sediment that could otherwise inhibit survival and/or growth. 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.

Attachment B 1s a letter from Mr. Hosemann In which he agrees with John Chance's conclusions and addresses shallow hazards at proposed well sites. 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. 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. 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. Installation was completed in Q4 2015, with production start-up slated for mid-2016. In the North Sea, significant Lophelia has been documented on numerous oil and gas platforms and these populations have been called an ‘oasis on the sea bed where life is relatively sparse’ (Gass & Roberts, 2004). Viosca Knoll 862 was Walter’s first subsea oil project as well as one of the company’s early horizontal well completions. At this site, the corals had less-calcified, fragile skeletons (“gracilis” morphotype [ 12 ]), and there was no hydrocarbon seepage. the head of De Soto Canyon (archived at the US National Museum) and Viosca Knoll. Walter then acquired a proprietary 3D survey that revealed a number of untested amplitude anomalies to the west of the platform. The areas around this HAPC are used to fish for royal red shrimp.

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 … Leiopathes sp. At this site, the corals had less-calcified, fragile skeletons (“gracilis” morphotype [12]), and there was no hydrocarbon seepage. 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). There are numerous platforms in close proximity to the VK reefs. However, in the early 90s, Walter obtained a new survey that utilized advancements in 3D processing and acquisition techniques. 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). While several previous wells had been drilled on the block, commercial reserves had not been established. 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. Walter has drilled three additional wells, two of which are flowing back to a fixed-leg platform in VK 817. Walter drilled its first well in VK 862 in 1995, hoping to find enough reserves to justify setting a platform in approximately 1000’ of water. … At this site, the corals had less-calcified, fragile skeletons (“gracilis” morphotype [ 12 ]), and there was no hydrocarbon seepage. 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.

During the Lophelia I studies, we collected samples from three natural Lophelia sites, Viosca Knoll (VK) 826, VK 862, and Green Canyon. When Walter first leased the block in 2006, existing 3D seismic data revealed shallow oil on the northern flank of a salt dome. It is literally a wall of coral. 2. Back in the lab, we will use variable genetic markers developed for Lophelia to obtain a ‘genetic fingerprint’ for each sample. Figure 2.
