Uncommon in our industry, South Bay Cable has been owned and operated by the same management since 1957! We've designed and manufactured over 60,000 different cables meeting our customers most demanding requirements. Contact the uncommon leader . SOUTH BAY CABLE CORP rine protected areas (MPAs) by 2020. The AOI aims to protect ecologi- cally and biologically significant areas, including underwater seamounts and hydrothermal vents. Universal Wing Cuts Tow Cable Length Needs One of the problems encountered when towing oceanographic instru- ments is the cable length required to get the equipment to the optimal depth. A typical ratio of cable length to tow depth is 4 to 1. Increase the tow speed, and even more cable is needed. To overcome this problem a down- rigger weight or depressor wing is commonly used. The wing operates on the principle of hydrodynamic depres- sion, rather than just weight, to over- come the limitation of conventional downrigger systems. When using a wing, the ratio of cable length to tow depth is cut in half. JW Fishers has created a universal wing that could be used with any type of equipment: the DDW-1 deep dive wing. Universities, salvage companies, government agencies and military units worldwide are using this wing to tow a variety of oceanographic equip- ment, including side scan sonars, mag- netometers, metal detectors, video sys- tems, hydrophones and more. Funding for Oil, Gas Digital Knowledge Resource A major digital resource developed for the oil and gas industry, "Encom- passing the Future: Offshore Oil & Gas Operations, Environment Safety and Performance Management," has received £50,000 from the Scottish government. This supplements the £800,000 received from industry, uni- versities and other sponsors to enable the research, development and launch of this multidisciplinary project. The International Centre for Oil and the Environment (ICOE) is working with industry, academia and regulators to produce this resource of authorita- tive and researched material on the successful development of the North Sea offshore. PADI, Mission Blue Partner To Protect Oceans PADI and Mission Blue, led by the legendary oceanographer Dr. Sylvia Earle, have partnered to help increase protection of the world's ocean. A glob- al campaign will build public support for the protection of Hope Spots, spe- cial places that are vital to the health of the ocean. By activating its global net- work of divers and dive professionals, PADI will increase attention to marine areas. PADI will showcase a different Hope Spot each month. PADI divers and members will have an opportunity to nominate new Hope Spots. Virginia at the Top of Hard-Clam, Oyster Production Virginia shellfish farmers sold $56.6 million in clams and oysters in 2016, with hard clam sales of $38.1 million and $18.5 million in oyster sales. The state's hard-clam production once again leads the nation, and its oyster production is top among East Coast states. The values are according to the 11th annual Virginia Shellfish Aqua- culture Situation and Outlook Report, a survey conducted by the Marine Ad- visory Services program at the Virginia Institute of Marine Science. It is an an- nual assessment of trends and projec- tions for Virginia's shellfish aquacul- ture industry. ST
