Offshore Salmon Farming
On Continental Shelf

Erko Seafood AS and Global Maritime AS have developed a new concept for offshore salmon farming, called the North Sea Fishfarm. It will use a stationary base as a fish farming platform in the open sea to benefit from larger production areas and volumes.

The concept should also see great advancements in counteracting fish lice’s impact on wild salmon and preventing contamination and runoff into the local environment.


OHI Uses Data Software
For Improved Workflow

In 2012, scientists at UC Santa Barbara’s National Center for Ecological Analysis and Synthesis (NCEAS) launched the Ocean Health Index (OHI), a scientific framework to measure and track the health of the world’s oceans. Working with Conservation International, the OHI team measured the combined benefits that oceans sustainably provide for people. Annual status reports show how and where to improve ocean management.

Now, OHI researchers are transforming the way marine scientists engage with coastal management by leveraging practices and tools used by Silicon Valley software developers to promote teamwork. Employing free software solutions that upgrade collaborative research, the team has been able to make its entire workflow more transparent and streamlined while enhancing the reproducibility of their data methods.

This new approach has made OHI methods available to everyone. For example, the governments of Mexico and Indonesia and scientists in Sweden assessing countries on the Baltic Sea are using OHI science and code for their own coastal management.


Rebuilding of Shoreline
In Dare County, NC

BOEM will aid Dare County, North Carolina, in rebuilding its coastal shoreline in several locations.

The Town of Southern Shores is conducting a small beach nourishment project at the southern portion of the town, rebuilding about 2,500 ft. of shoreline. The project has been incorporated into the agreement that BOEM and Dare County signed in September 2016, adding 120,000 cubic yards of offshore sand for Southern Shores coastal restoration. Completion is expected in August.

The agreement also authorized 4.825 million cubic yards of offshore sand to restore 8 mi. of Atlantic shoreline for the towns of Duck, Kitty Hawk and Kill Devil Hills, also scheduled for this summer.

BOEM coordinated with the U.S. Army Corps of Engineers and the North Carolina Division of Coastal Management for the beach nourishment.


Canada Designates Area
Of Interest for Large MPA

Canada is moving forward on its plan to protect 5 percent of its marine and coastal areas by 2017 and 10 percent by 2020 by designating a new area of interest (AOI) off the coast of British Columbia, with the intention of making it one of Canada’s largest marine protected areas (MPAs) by 2020.

The AOI aims to protect ecologically 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 instruments 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 downrigger weight or depressor wing is commonly used. The wing operates on the principle of hydrodynamic depression, rather than just weight, to overcome 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 equipment, including side scan sonars, magnetometers, metal detectors, video systems, hydrophones and more.


Funding for Oil, Gas
Digital Knowledge Resource

A major digital resource developed for the oil and gas industry, “Encompassing 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, universities 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 authoritative 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 global campaign will build public support for the protection of Hope Spots, special places that are vital to the health of the ocean. By activating its global network 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 Aquaculture Situation and Outlook Report, a survey conducted by the Marine Advisory Services program at the Virginia Institute of Marine Science. It is an annual assessment of trends and projections for Virginia’s shellfish aquaculture industry.
