Breaking The Ice For Coast Guard Authorization

Unless you’re golfing, being down 40-1 is not a good way to end a game, but that’s currently the score in the Russia vs. U.S. Arctic turf war. Moscow stands as the military and exploration leader at the top of the world with their massive fleet of 40 icebreakers, compared to our single functioning heavy icebreaker (a second has been out of service since 2010, and the newest addition to the fleet is classified as a medium icebreaker).

Climate Change Indicator: Arctic Ocean Getting Warmer, Becoming More Like The Atlantic

2017-04-07T13:48:07+00:00 April 7, 2017|

A large international team of researchers has found another troubling indicator of climate change: the Arctic Ocean around the North Pole is getting warmer, and in the process, becoming more like the Atlantic Ocean to its south. Specifically, the eastern Eurasian Basin is now more ice-free and showing mixing of vertical layers of water, a phenomenon common in the Atlantic. Record-breaking loss of sea ice has become a common feature in the Arctic every summer the last 10 years or so. Since 2011, the eastern Eurasian Basin region has been nearly free of ice at the end of every summer.

Close Connection Between Deep Currents And Climate

Mild winters in northern Europe, rainfall in western Africa, hurricanes in North America - the energy transported around the world by the global ocean circulation affects the climate as well as regional weather phenomena. One of the key regions for the ocean circulation is the Labrador Sea between North America and Greenland. There warm, saline waters coming from the south near the sea surface cool down and sink to the depth. There the water masses flow back to the south along the continental margin. Thereby the area is one of the regions of crucial importance for the global ocean circulation.

U.S. Coast Guard’s Role In Maritime Security

2017-03-27T15:41:20+00:00 March 27, 2017|

The passenger cruise ship Crystal Serenity, with more than 1,700 passengers onboard, became the largest commercial cruise ship to navigate the Northwest Passage in August 2016. As a result of increasing maritime traffic and human activity in the Arctic, the U.S. Coast Guard is keeping a close eye on their ability to maneuver in the region.

Stressed Seabird Parents Think Only Of Themselves

2017-03-17T12:59:47+00:00 March 17, 2017|

Stress is a factor not only in the best human families; it also appears among animals. To see how bird family members interact with each other in stressful situations, researchers from Vetmeduni Vienna and the University of Gdansk, Poland, studied parent-offspring interactions in a long-lived seabird, the little auk (Alle alle).

NASA Study Improves Forecasts Of summer Arctic Sea Ice

2017-03-13T13:21:32+00:00 March 13, 2017|

The Arctic has been losing sea ice over the past several decades as Earth warms. However, each year, as the sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.

Polar Algae Survive More Than a Year in Space

2017-02-17T10:40:19+00:00 February 17, 2017|

For 530 days, two algal species withstood extreme temperatures and ultraviolet radiation that would quell most other life on Earth. Part of a long-term plant study conducted aboard the International Space Station (ISS), the algae were left to grow on a panel outside the ISS for more than a year-and-a-half. Preliminary analyses of the specimens, released February 1, suggest that the plants are doing just fine.

Engineers Help Arctic Ships Assess Ice Buildup

2017-02-17T10:29:51+00:00 February 17, 2017|

As global temperatures rise and arctic ice melts, more ships are taking advantage of expedient, yet dangerous ocean routes that are opening in the polar region. One of the main hazards of sailing in freezing temperatures is topside icing, in which water blown from the ocean freezes once it contacts a ship, potentially accumulating enough ice to put the vessel at risk of capsizing.

High Levels of Black Carbon Discovered in Siberia, Which Could Speed Up Arctic Thaw

2017-02-01T12:45:17+00:00 February 1, 2017|

There is more soot in remote Siberia than at the edge of densely populated Europe, even though there are hardly any people there, the first in-depth study of black carbon in the region has found. In Tiksi, a small town in an isolated region of north-eastern Siberia, the levels of black carbon emitted by traffic is at higher levels than in Sweden, according to the two-year study published in the journal PNAS. Before this study, black carbon levels in this part of Russia were a blank spot on the map.

Arctic Pollution Is So Bad That Polar Bear Cubs Are Feeding On Contaminated Mothers’ Milk

2017-01-11T11:25:48+00:00 January 10, 2017|

Pollution in the Arctic is so bad that chemicals are accumulating in polar bear mother's milk and getting passed onto bear cubs. A new analysis of pollutants in the Arctic has found that polar bears are at a particularly high risk, compared to other animals like seals. The study was published in the journal Environmental Toxicology and Chemistry in December and focused on a class of pollutants known as persistent organic pollutants (POPs). POPs are toxic, hang around for a long time, and tend to build up in the bodies of humans and animals.

Federal Regulations And Rulemaking Process Targeted In Bills Introduced In First Days of 115th Congress

2017-01-09T15:28:43+00:00 January 9, 2017|

It took a matter of hours after the 115th Congress was sworn in on January 3 for bills to be introduced in the House that would significantly impact executive branch regulations and rulemaking. The Midnight Rules Relief Act of 2017 (H.R. 21) and the Regulations From the Executive in Need of Scrutiny (REINS) Act (H.R. 26) both passed the House (along nearly party-line votes) less than 56 hours after the start of the session.
