BLOG: Buoy deployments in the Arctic on board the Korean icebreaker RV Araon

RV Araon Blog ICE-ARC PI Jeremy Wilkinson (British Antarctic Survey) is currently on board a cruise operating by the Korean Polar Research Institute (KOPRI) on the Korean ice breaker RV Araon. During the cruise from Nome, Alaska to the Chukchi Sea a number or autonomous instruments will be deployed, the instruments are designed capture and communicate direct measurements… Read more »

SATICE Buoy Deployments

ICE-ARC partner CSIC are deploying a series of SATICE buoys. SATICE, is the first high-rate, high-precision positioning experiment on sea ice in the Arctic Ocean. It consists of an array of five polar GPS buoys operating simultaneously. Each buoy collects continuous GPS data while drifting on sea ice. Data from each buoy is streamed over… Read more »

Thawing permafrost and freshwater drive Arctic Ocean acidification

Acidification off the coast of Northern Siberia in the Arctic Ocean is caused by increased thawing permafrost and freshwater discharge. Importantly, acidity levels of the region are much higher than previously predicted, according to a new study published in journal Nature Geoscience. The study, carried out by researchers Igor Semiletov, Natalia Shakhova and colleagues, was… Read more »

Summer Buoy Deployments

By Christine Provost, Senior Marine Scientist, Université Pierre et Marie Curie (UPMC) ICE-ARC scientists participated to two summer campaigns on board icebreakers to deploy autonomous instruments. One cruise was operated by the Korea Polar Research Institute (KOPRI) on the Korean icebreaker Araon in July (Nome-Barrow), the second was the Transarc II cruise operated by the Alfred Wegener Institute… Read more »

Buoy deployments on Arctic sea ice

It is not common to encounter research vessels cruising through the Arctic ice pack in mid-winter. Thick and consolidated ice, polar night, and extreme weather conditions do not allow researchers to widely study the Arctic system in the winter months. This year, a great opportunity came up with R/V Lance being frozen into the Arctic… Read more »

The sun is still under the horizon in the North Greenland settlement Qaanaaq at the north side of the fjord Inglefield Bredning. It will return on February 17th after three months of winter darkness. Anyway, to the South during the afternoon there is a bright stripe across the sky. Enough light for working outside a… Read more »

Retreat of Arctic sea-ice: A scientific perspective

Retreat of Arctic sea-ice: A scientific perspective   Jeremy Wilkinson, ICE-ARC Programme Coordinator, British Antarctic Survey   The retreat of summer Arctic sea ice is unquestionable.  The use of the word unquestionable is deliberate as for over 35 years special satellite-mounted sensors, which can see through cloud and the polar night, have been continuously obtaining… Read more »

ICE-ARC deploys buoys with help from the USA and South Korea

In August the South Korean icebreaker Araon sailed into the northern region of the Beaufort/Chukchi Sea region of the Arctic Ocean.  This scientific cruise, a collaborative effort between ONR’s Marginal Ice Zone programme (USA) and the Korea Polar Research Institute (KOPRI), aims the further our understanding of the changing Arctic marine environment. At about 77.4N… Read more »
