Mother Ship with USV Flotilla Could Boost Coast Guard Capabilities
range monitoring and on-scene presence, possibly up to 400 NM. This could allow two or three flotillas to monitor the Labrador Sea from Newfoundland up through Baffin Bay. Similarly, one mother ship and flotilla could monitor much of Hudson Bay. Another application could be the Gulf of Alaska and the Bering Sea.The USVs could be controlled from the mother ship or operate autonomously under some conditions. They would be suitable and seaworthy for the purpose intended and could have sufficient fuel capacity for 40 to 60-day endurance at moderate speed.The mother ship may be reinforced to withstand moderate
Grander Canyons
There are subsea canyons far bigger than the Grand Canyon.The Grand Canyon is 6,093 feet (1,857 meters) deep, but the Zhemchug Canyon, located in the middle of the Bering Sea, is 8,530 feet (2,600 meters) deep.The Grand Canyon is 277 miles (446 kilometers) long, but the Kroenke Canyon in the western Pacific Ocean is 480 miles (700 kilometers) long. It is the longest and the most voluminous submarine canyon yet discovered.There are around 10,000 submarine canyons on Earth, covering around 11% of the continental slope, and they are an important source of ocean biodiversity, they transport sediment and
NOAA Reveals Names of its New Mapping Vessels
weight. It not only pays homage to NOAA's mission but also honors two previous vessels that bore the same name. The first Surveyor, launched in 1917, was the first oil-burning steamer in the Coast and Geodetic Survey fleet, a precursor to NOAA. This ship primarily operated in the North Pacific and Bering Sea, playing a key role in ocean surveying. Surveyor Bay in Alaska was named in recognition of its contributions during surveys conducted in 1936. The second Surveyor served from 1960 to 1995, conducting hydrographic surveys across diverse locations, from Alaska’s Norton Sound to American Samoa
Kongsberg Discovery Partners with Arctic Storm for Advanced US-built Trawler-processor
from Kongsberg Discovery tailored to locate, inspect, and engage fish with unparalleled efficiency.The 100-meter-long Arctic Fjord, designed by Kongsberg Maritime and built by Louisiana’s Thoma-Sea Marine Constructor, will start full-time operations for 2024’s pollock A season in the Bering Sea.Speaking ahead of this week’s Pacific Marine Expo in Seattle, Washington, Kongsberg Discovery reveals that the vessel, which replaces Arctic Storm’s original, 1974-built Arctic Fjord vessel, is outfitted with systems designed to optimize both efficiency and environmental performance
The Information Age is Transforming Fishing Worldwide
for each fisherman, have helped curb overfishing. Imposing catch shares can be highly controversial, but since the year 2000, 47 U.S. stocks that were overfished and shut down have been rebuilt and reopened for fishing, thanks to policy judgments based on the best available science. Examples include Bering Sea snow crab, North Atlantic swordfish and red grouper in the Gulf of Mexico.A growing “fishie” movement that mirrors the widespread “foodie” locavore movement has been gaining steam for more than a decade.

The Arctic: Scientists Aim to Improve Sea Ice Predictions' Accuracy, Access
in the Arctic declines, thins and becomes more mobile, accurate forecasts are becoming even more vital for things like fisheries and resource development, shipping, subsistence activities and wildlife management.Bhatt said the SIPN team hopes to work with the Alaska maritime industry, especially the Bering Sea snow crab fishermen, to make ice forecasts even more accurate and useful to those who work in or live next to the world’s polar waters and to scientists studying sea ice decline and the Arctic climate.The SIPN team plans to enhance sea-ice predictions by including data for sea-ice thickness
MTR100: Saildrone takes USVs to the Next Level
, unmanned space.“As you know, (because of COVID), when everyone was locked down, all the government ships were stuck in port (which presented) huge vulnerabilities to the nation for security rules in fisheries,” said Jenkins. “Every year, we do a fish stock survey in the Bering Sea, it’s part of the pollock fish stock assessment for NOAA fisheries. And the NOAA ship that normally does that was unable to get to the fisheries’ grounds. So they were going to have to essentially guess a fish stock assessment based on previous years. But we managed to sail three vehicles
Climate Change is Flooding the Arctic with Light – and New Species
singling out species that have caused harm elsewhere and that could endure Arctic environmental conditions. Nearly two dozen potential invaders show a high chance for taking hold in Arctic Canada.© shorex.koss / Adobe StockAmong these is the cold-adapted red king crab, native to the Sea of Japan, Bering Sea and North Pacific. It was intentionally introduced to the Barents Sea in the 1960s to establish a fishery and is now spreading south along the Norwegian coast and in the White Sea. It is a large, voracious predator implicated in substantial declines of harvested shellfish, sea urchins and other
Winter Sea Ice in Bering Sea Reached Lowest Levels in Millennia
The Bering Sea ice cover during the winters of 2018 and 2019 hit new lows not seen in thousands of years, scientists reported on Wednesday, adding to concerns about the accelerating impact of climate change in the Arctic.Satellite data provides a clear picture of how sea ice has changed over the last four decades in the region between the Arctic and northern Pacific oceans. Beyond that, the only ice records available were those recorded in ship logs and other observations.So scientists turned to peat land, which holds organic compounds from plants dating back millennia, on the remote St. Matthew
