They call it “ice liberty,” a tradition during the Coast Guard’s maritime missions in Arctic waters. At a thick ice floe, the crew gets to disembark for a brief moment

This has been, in part, a training mission for the 85 crew members, a task that has added importance as the Coast Guard prepares to increase the U.S. Arctic presence with three new icebreakers that later in this decade are planned to be homeported in Seattle.

They call it “ice liberty,” a tradition during the Coast Guard’s maritime missions in Arctic waters. At a thick ice floe, the crew gets to disembark for a brief moment of freedom from the vessel confines. Some play touch football, or bring hockey gear for the occasion. Others just take a stroll.

With the Arctic melting, the U.S. and Canada are trying a cooperative approach to tapping the region’s thawing resources and trade routes.

Countries must collaborate on a vital effort to finish the job by 2030.

From coast to coast in the U.S., to American Samoa, and back to Lake Huron, the autonomous surface vessel is in Rogers City this month for lake floor mapping.

Justine Paradis Even in the quietest of times, sand beaches are defined by movement and change. “I think its fair to say the beach is one of the most flexible or dynamic, if you will, habitats in the world. It’s super geologically unstable,” said coastal ecologist Dr. Bianca Charbonneau, also known as “the Dune Goon.” On this edition of 10x10, we examine the systems and feedback loops on and around the sand beach, the science taking place there, and how the way beaches are changing ...

Saildrone Launches 72-foot Surveyor (Photo: Saildrone) Saildrone has launched the Saildrone Surveyor, a new 72-foot uncrewed surface vehicle (USV) equipped for high-resolution mapping of the ocean seafloor. The Surveyor carries a sophisticated array of acoustic instruments for both shallow and deep-water ocean mapping; the Kongsberg EM 304 multibeam echo sounder is capable of mapping the seafloor down to 7,000 meters below the surface. The Surveyor also carries two state-of-the-art Acoustic Dop...

Numbers and then will be the computer programs and the trig nom tri algorithms they used to plot out. show your work? thats what it is. >> youre talking about a moving plane and moving satellies. so let me ask you this, do you think that any of this may change how and where the search is being conducted. >> well, i do. >> they are now putting in the australians and malaysians. they want two private companies to bid. one theyre going to map the ocean floor. they are in talks with an ocean mapping...

Believe. >> go ahead. >> well, i know we have this map here, and i think we have it ready. the ememmersat data, we were ab to draw that arc in the southern part of the south indian ocean where the plane may have been. it is interesting to see where that arc is in relation to where this new area is, where they detected the sound, and its pretty close. we may not have it ready yet, but when you look at how close it is that is pretty interesting to see, fred. >> and now what could potentially happe...
