US Navy Submarines Surface in the Arctic Circle

;   The first Arctic under-ice operations by submarines were done in 1947-49. On August 1, 1947, the diesel submarine USS Boarfish (SS-327), with Arctic Submarine Laboratory's founder Dr. Waldo Lyon onboard serving as an Ice Pilot, conducted the first under-ice transit of an ice floe in the Chukchi Sea.   In 1958, the nuclear-powered USS NAUTILUS made the first crossing of the Arctic Ocean beneath the pack ice. The first Arctic surfacing was done by USS Skate (SSN 578) in March 1959. USS Sargo was the first submarine to conduct a winter Bering Strait transit in 1960.    The

Alaska Requests Limits on US Offshore Drilling

has asked U.S. Interior Secretary Ryan Zinke to pare back a Trump administration plan for oil and gas leasing off the state's coast.   While Walker supports offshore oil development, he said the Interior Department should focus on the most prospective areas off Alaska – the Beaufort and Chukchi seas in the Arctic and Cook Inlet in southern Alaska – and drop all others from the leasing plan.   In asking for proposed lease sales to be dropped, Walker, an independent, joins governors of several other coastal states after Zinke's unexpected move to exempt Florida from the department's

Ice Analysis in the Chukchi Sea

Tom Weingartner of the University of Alaska's College of Fisheries and Ocean Sciences and ASL are wrapping up the analysis of the 2014-15 ice draft, ice drift and current data from the Chukchi Sea Environmental Studies Program (CSESP) through funding from BOEM (Bureau of Ocean Energy Management). The completion of this analysis marks a milestone in a series of collaborations to better understand the Chukchi Sea.   Two of the sites being analyzed have been observed since Shell Exploration and Production first started making measurements in the Chukchi Sea in 2008. Since those first deployments

that allows presidents to limit areas from mineral leasing and drilling. Environmental groups said that meant Trump's incoming administration would have to go court if it sought to reverse the move.   The ban affects 115 million acres (46.5 million hectares) of federal waters off Alaska in the Chukchi Sea and most of the Beaufort Sea and 3.8 million acres (1.5 million hectares) in the Atlantic from New England to Chesapeake Bay.   Trump, who succeeds Obama on Jan. 20, has said he would expand offshore oil and gas drilling. A recent memo from his energy transition team said his policy could

Arctic Sea Ice Melt Continues

As of August 14, Arctic sea ice extent is tracking third lowest in the satellite record, according to the National Snow & Ice Data Center (NSIDC). The southern route through the Northwest Passage appears to be largely free of ice. Despite a rather diffuse ice cover in the Chukchi Sea, it is unlikely that Arctic sea ice extent this September will fall below the record minimum set in 2012.   Overview of conditions As of August 14, Arctic sea ice extent was 5.61 million square kilometers, the third lowest extent in the satellite record for this date and slightly below the two standard deviation

Hundreds of Scientists Urge Obama to Halt Arctic Oil Drilling

gas leasing or exploration should be allowed in the Chukchi and Beaufort seas in the foreseeable future,” the scientists said.    The proposed federal oil and gas leasing program would last from 2017 to 2022 and includes two sales in the Arctic Ocean: the Beaufort Sea in 2020 and the Chukchi Sea in 2022.   The letter urged the administration to consult native Alaskan groups on any further Arctic developments.   The scientists said in the letter that expanding Arctic marine protection would help counter the effects of climate change.   “The Arctic is home to

High Correlation of Biomass to Species Diversity in Northern Chukchi Sea - BOEM Study

Last summer, researchers began a five year study to monitor biodiversity in the Arctic Chukchi Sea from an ecosystem perspective, looking at microbes, whales and everything in between. Marine biodiversity is a key indicator of ocean health and critical ecosystem services that contribute to human life. Monitoring it improves our ability to interpret and forecast changes. The unprecedented effects of climate change combined with strong seasonal cycles and increasing human activities in the Arctic make this region particularly important to monitor. In August 2015, the AMBON team of researchers from

In September, a team of archaeologists from the Maritime Heritage Program in NOAA’s Office of National Marine Sanctuaries scoured a 30-mile stretch of coastline in the nearshore waters of the Chukchi Sea, near Wainwright, Alaska. Previous searches for the ships had found traces of gear salvaged from the wrecks by the local Inupiat people, as well as scattered timbers stranded high on the isolated beaches that stretch from Wainwright to Point Franklin.   Using state-of-the-art sonar and

Shell Terminates Polar Pioneer Contract

Royal Dutch Shell has elected to terminate the contract for harsh environment semisubmersible rig Polar Pioneer prior to its expiration in July 2017, the rig's owner Transocean Ltd. announced. Transocean said it will be compensated for the early termination through a lump-sum payment that includes adjustments for reduced operating costs and demobilization to Norway.   Shell initially intended to use the rig for its Arctic operations in the Chukchi Sea, but called off the campaign in September.

Update: Statoil Follows Shell out of Alaska

Norwegian oil major Statoil said on Tuesday it will pull out of Alaska's Chukchi Sea, just weeks after Royal Dutch Shell abandoned the treacherous waters there after spending billions on oil exploration work.   The latest pullback comes as oil companies slash spending on expensive offshore projects during the worst price crash in six years. Businesses, politicians and environmental groups have squared off over drilling in the Arctic, which is widely believed to have large undiscovered oil resources.   Statoil said it will exit 16 leases it operates and its stake in 50 leases operated by

Norway's Statoil to Exit Alaska

Norwegian oil major Statoil said on Tuesday it will pull out of Alaska as its exploration leases in the Chukchi Sea no longer looked competitive.   "Since 2008 we have worked to progress our options in Alaska. Solid work has been carried out, but given the current outlook we could not support continued efforts to mature these opportunities," Statoil exploration chief Tim Dodson said in a statement.   The firm will exit 16 Statoil-operated leases, and its stake in 50 leases operated by ConocoPhillips.     (Reporting by Stine Jacobsen)
