Aurora Expeditions Christens Sylvia Earle

Aurora Expeditions, the luxury cruise company that offers services to Antarctica and Arctic,  will build a second expedition ship, the Sylvia Earle, scheduled to debut in October 2021.The 126-passenger vessel  named ‘Sylvia Earle’, to honor the renowned marine biologist, oceanographer and explorer.The order comes shortly after the Australia-based company introduced its first new expedition ship in 2019, the Greg Mortimer, named for the Australian mountaineer and Aurora’s founder.The new ship is one of the vessels in owner, SunStone Ships’, INFINITY class.

Notably, he commanded the frigate HMS CUMBERLAND on counter-piracy patrol off Somalia and the UK’s Ice Patrol Ship, HMS PROTECTOR, in Antarctica. In addition to this, he commanded the 44 units (aircraft carriers, destroyers, frigates, mine-hunters, patrol vessels, and the maritime explosive ordnance disposal teams) of the Portsmouth Flotilla.Ashore, Peter Sparkes has served in Ministry of Defense acquisition appointments and was responsible

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. The £200 million investment represents the UK Government’s largest investment in polar science since the 1980s

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

the custom cable for dozens of missions, in regions as diverse as the Arctic to the tropical waters of Polynesia. It has proven ideal for the expeditions, carried out every two years since 2008. It is set to be deployed again in 2021. Near identical cables are now in use in China, Germany, India and Antarctica.We’ve learned through experience that cables used in dynamic subsea environments have to be custom designed and built for the specific harsh environments our customers encounter. The properties of synthetic strength members and outer jackets can make the difference to scientific expeditions

The Oceans Are Warming Faster than Expected

Reuters.Among effects, extra warmth can reduce oxygen in the oceans and damages coral reefs that are nurseries for fish, the scientists said. Warmer seas release more moisture that can stoke more powerful storms.Warmer ocean water also raises sea levels by melting ice, including around the edges of Antarctica and Greenland.(Reporting By Alister Doyle; editing by John Stonestreet
