5:15 p.m. It's over. The Symposium concluded with the presentation of awards for the best student presentations but most of the winning students were not there, presumably back at their studies.

3:30 p.m. -- Mark Brzezinski, the White House's point man for the Arctic, told participants at the Marine Science Symposium this afternoon that they're in a growth industry.

LIVEBLOG PREVIEW: This is the week when a whole lot happens in Arctic science. The latest results from last year's field season begin to go public, by way of hundreds of speeches, powerpoints and poster presentations before about 800 people in downtown Anchorage. It's more information than anyone could possibly absorb, but they'll try.

The climate changes that have swept through Alaska are now being reflected in our landscape and wildlife - avalanches, fires, species declines, the list goes on. APRN: Tuesday, 1/26 at 10:00amListen now

It’s a unique moment in broadcasting, and it only happens once a year in Alaska. If you ever doubted that Alaska is the world’s biggest small town, you’ll hear proof on the annual two-hour holiday edition of Talk of Alaska.APRN: Tuesday, 12/22 at 10:00amListen now

It's the dead of winter, and that means it's time to light up the movie screens of Alaska for the Anchorage International Film Festival, followed by the "best of the fest" tour state-wide. Will that include your community?APRN: Tuesday, 12/8 at 10:00amListen Now

Flying blind. No Alaska pilot wants to, but sometimes it happens. And sometimes it’s not on an established flight corridor. A new terrain mapping effort is underway, and it's not just aviators who will benefit.APRN: Tuesday, August 18, at 10:00 a.m. and 8:00 p.m.Download Audio:

The Iditarod Trail began as a mail route and became a protected corridor and recreational resource. Even if climate change puts an end to its use by dog mushers, the evolution of the Iditarod Trail will continue. In their own way, our corridors tell the story of Alaska, and we’ll be exploring a few of those pathways on the next Talk of Alaska.APRN: Tuesday, 3/3 at 10:00 a.m.Download Audio

What if what we call the natural world no longer really exists, and we live already in a world of our own creation? There is growing evidence that human activity has triggered a new geological era. Scientists are debating whether the evidence we leave behind in the layers of the earth will be plastic, nuclear isotopes, changed biomass indicators, or other things, but they agree that humans have actually changed the planet. The question is – how do we take responsibility for that, and what can we do from this point on? It’s a question that means a lot for Alaska, and it’s what we’re talking about on the next Talk of Alaska.APRN: Tuesday, 2/24 at 10:00 a.m.Download Audio

Shellfish are particularly vulnerable to ocean acidification, and colder waters are becoming more acidic than warm waters. What does this mean for Alaska and its fisheries – especially crabs and oysters? Or for the food chain that feeds other species in the ocean? The answers are beginning to come in from the scientific world, and we’ll learn more about ocean acidification on the next Talk of Alaska.APRN: Tuesday, 2/17 at 10:00 a.m.Download Audio
