Study Identifies "Collision Map" For Birds, Boats to Support Conservation Efforts
, with 170 million individuals exposed to bycatch risk worldwide.In the Southern Hemisphere alone, 40,000 albatrosses and petrels are caught each year, and up to 90% of albatross species are now threatened by fishing activity. The Antipodean albatross, in particular, is at extreme risk. Endemic to New Zealand, the population of roughly 28,000 birds is declining at 6% per year – a devastating rate driven primarily by bycatch from high-seas longline fishing.With the species being driven toward extinction, researchers needed to understand exactly where and when these fatal encounters are occurring

Money Pours in for Hull Cleaning Technology
, image processing technology adapted for turbidity, particulate matter, and other undersea conditions, and real-time self-position estimation systems.Meanwhile, the Port of Auckland is in the final stages of developing an in-port biofouling solution to clean niche areas of ships in partnership with New Zealand Diving and Salvage Limited. The technology is new and Port of Auckland and NZDS are keeping the details of how it works under wraps while it seeks IP protection
CCAMLR Talks End Without Consensus on Krill Fishing
Coalition (ASOC). “Key proponents refused to compromise on science, stood united in defense of marine life, and sent a clear signal that CCAMLR’s founding purpose of conservation must come first.”A strong show of unity from Chile, Argentina, the European Union and its member states, New Zealand, the Republic of Korea, and other members, successfully resisted attempts to expand krill fishing in predator-rich areas without safeguards for penguins, seals, and whales.At the heart of the meeting were two intertwined issues: the proposed marine protected area (MPA) for the Antarctic Peninsula
One Fish, Two Fish
algorithms for seven species: Atlantic salmon (Salmo salar), cobia (Rachycentron canadum), European sea bass (Dicentrarchus labrax), gilthead seabream (Sparus aurata), king salmon (Oncorhynchus tshawytscha), red snapper (Lutjanus peru), and yellowtail (Seriola rivoliana).Innovasea collaborated with New Zealand King Salmon, the largest producer of farmed King Salmon – supplying over 50% of the world’s species. New Zealand King Salmon routinely tracks fish growth to meet critical production benchmarks in advance of each harvest. Doing so requires meticulously tracking their different strategies

Redwing Glider Successfully Launched in Global Ocean Mission
on the five-year Sentinel Mission, where it will become the first autonomous underwater vehicle (AUV) to circumnavigate the globe.Redwing’s journey will take it across the Gulf Stream towards Europe, then south to Gran Canaria, onward to Cape Town, across the Indian Ocean to Australia and New Zealand, through the Antarctic Circumpolar Current, and eventually back to the Atlantic via the Falkland Islands, Brazil, and the Caribbean.The mission is a collaboration between Teledyne Marine and Rutgers University. Engineers from Teledyne, alongside more than 50 students from Rutgers University -
Underwater Autonomous Glider Departs to Circumnavigate the Globe
ride the Gulf Stream south of Martha’s Vineyard toward Europe, before sweeping south to stop at Gran Canaria off the coast of North West Africa. Its next leg will take it to Cape town in South Africa, before crossing the Indian Ocean to stop at Perth in Western Australia, then on to Wellington, New Zealand. It will then navigate the Antarctic Circumpolar Current — the most powerful current on Earth — taking it on its longest leg to the Falkland Islands. From here there will be possible stops in Brazil and the Caribbean before heading back to Cape Cod in the U.S.Transmitting information
