NATO RV Alliance is not just quiet, it’s ice-capable

most research ships coming out now are quiet enough.Are there ships out there today that meet those “aspirations?”There are other very good ships out there.  The Norwegian’s brand new PC-3 class icebreaking research vessel Kronprins Haakon will be operating in both the Arctic and Antarctic.  It is an absolutely phenomenal vessel.Is it quiet?Nothing is as quiet as Alliance, but do we need her to be that super, super quiet? We may, because things change in the submarine world.  But we can also use autonomous offboard systems.  We’re not in the game of towing miles

Polar RV Sir David Attenborough Naming Ceremony

Thursday, 26 September, the ceremonial naming of the new British polar research ship RRS Sir David Attenborough will take place at the Cammell Laird Birkenhead shipyard.The ship was commissioned by the UK’s Natural Environment Research Council, built by Cammell Laird, and operated by the British Antarctic Survey. This vessel is designed to transform how ship-borne science is conducted in the Polar Regions and its commissioning is part of a major UK Government polar infrastructure investment program aiming to keep Britain at the forefront of world-leading research in Antarctica and the Arctic.

July: Earth's Hottest Month Ever Recorded

Atmospheric Administration (NOAA), July 2019 was hottest month on record for the planet and Polar sea ice melted to record lows.Much of the planet sweltered in unprecedented heat in July, as temperatures soared to new heights in the hottest month ever recorded. The record warmth also shrank Arctic and Antarctic sea ice to historic lows.The average global temperature in July was 1.71 degrees F above the 20th-century average of 60.4 degrees, making it the hottest July in the 140-year record, according to scientists at NOAA’s National Centers for Environmental Information. The previous hottest month

World First: Saildrone Circumnavigates Antarctica

A seven-meter (23-foot) long, wind-powered unmanned surface vehicle (USV) called a saildrone has become the first unmanned system to circumnavigate Antarctica.The vehicle, known as SD 1020, was equipped with a suite of climate-grade sensors and collected data in previously unchartered waters, enabling new key insights into ocean and climate processes.The 196-day mission was launched from Southport in Bluff, New Zealand, on January 19, 2019, returning to the same port on August 3 after sailing over 22,000 km (13,670 miles) around Antarctica. During the mission, the vehicle survived freezing temperatures

#Oi2020 History

In June 2010, it was announced by the National Oceanography Centre that its robot submarine-- Autosub3--was instrumental in the Centre’s study on the reasons behind the steady thinning of a vast glacier in Western Antarctica over recent decades. The now-retired robot submarine was deployed deep beneath a floating ice shelf by scientists investigating the thinning and acceleration of Pine Island Glacier. The study was led by Dr. Adrian Jenkins of the British Antarctic Survey (BAS), and also involved scientists from NOC in Southampton and the Lamont-Doherty Earth Observatory (LDEO) in the US.

Robotic Data Help Explain Mysterious Holes

The winter ice on the surface of Antarctica's Weddell Sea occasionally develops an enormous hole. In 2016 and 2017, one such hole drew intense curiosity from scientists and the media.Though bigger gaps had formed decades before, this was the first time oceanographers had a chance to truly monitor the unexpected gap in Antarctic winter sea ice. It was an opportunity that came about as a result of uncanny timing and a seasoned oceanographer’s knowledge of the sea.A new study co-authored by researchers from Scripps Institution of Oceanography at the University of California San Diego combines

SEAMOR: ROV to Last Ice Project in Canada

, is the most compact vehicle in the line. These ROVs are designed and manufactured in Canada by SEAMOR Marine Ltd. at their home offices in Nanaimo, British Columbia.SEAMOR ROVs have been used for marine research and inspections across the world. Our ROVs have also conducted geological research in the antarctic, ancient sea basins, and in the open ocean. We have also collaborated with other researchers too, including NASA, the Canadian Space Agency, and DARPA. The ROVs' applications are widespread too, as they have been used for a variety of fields from aquaculture, to dam inspection; underwater archaeolog

polar expedition ship, is currently under construction at Ulstein in Norway.The new expedition cruise ship features a range of state-of-the-art technologies that will help it to navigate safely through some of the world's most remote locations, including several planned cruises through Arctic and Antarctic waters.Wesmar’s EV860 sonar was chosen for the vessel for a variety of reasons, including its dual, forward-looking sonar and bottom profiler, the manufacturer said.“Wesmar has a very good product,” said Captain Leif Skog, Vice President Nautical, at Lindblad Expeditions. &ldquo

known as the Odyssey Class. These were roughly 21 inches in diameter and about 2 meters long. They were designed to dive as deep as 6,000 meters but be relatively affordable and easy to deploy. These vehicles supported many science missions including under-ice work in the Arctic and oceanography in the Antarctic. A key program supported by these vehicles, sponsored by the Office of Naval Research (ONR), was known as the Autonomous Ocean Sampling Network. This pioneered designs for docking AUVs. Experiments in seafloor mapping and mine hunting were also conducted during the first ten years of the AUV Lab
