  • Alaska is home to about 18,000 fishermen who harvest nearly 6 billion pounds of seafood each year. Salmon dominates the catch, five species in all: chum salmon, sockeye, king, coho and pink.

    For a taste of Alaska fishing life, we head out with a father-daughter fishing team as they go trolling for king salmon in the waters off Sitka, in southeast Alaska.

    We're on the Alexa K, a 45-foot steel-hulled troller, with captain Charlie Wilber, 69, and his 27-year-old daughter, Adrienne Wilber, "heading out into the briny deep!" as Charlie wryly tells us.

  • On June 4, 2017, Mike Murchison and Ray McGaughey will run the Steamboat Springs Marathon to raise money for Full Circle of Lake County.  Full Circle provides mentoring and outdoor leadership opportunities for the youth of Lake County, Colorado. These youth are predominantly the children of Latin American immigrants--or immigrants themselves--whose parents commute long hours each day to the resort towns of Vail, Breckenridge, and Aspen. Full Circle connects adult mentors in Leadville with 4th-6th graders in need of a stable, positive influences in their lives.

  • Christopher Rautman, Carleton Geology class of 1972 passed away May 12. Chris was a well known and liked geologist having spent 26 years at Sandia National Laboratories in Albuquerque, New Mexico prior to his retiring in 2011. After "retiring" Chris continued consulting with various firms, including a position with C Tech Development Corporation as chief geologist, volunteering as resident geologist at Philmont Scout Ranch, working in his woodshop and spending time with his wife, Janice,  kids and grandchildren. Chris was also a great supporter of Carleton and Carleton Geology having established the Chris Rautman endowed fund to support research and field experiences for students.

  • For well over a century, miners have clawed huge amounts of iron ore out of the red earth of northeastern Minnesota. Other companies are hoping to tap into the region's rich deposits of copper, nickel and precious metals.

    Now, scientists believed they've unlocked the key that could lead to another kind of mining in the region.

    Researchers with the Natural Resources Research Institute, an arm of the University of Minnesota Duluth, announced Thursday they've demonstrated on a pilot-scale a new technique to separate high-purity titanium oxide from a mineral called ilmenite.

    Titanium dioxide is valued around $3,200 per ton, compared to a value of around $70 for the taconite pellets produced on the Iron Range. It's used in a range of everyday products, "ranging from paint to lotions to lip balm to the white on your powdered donuts," said George Hudak, NRRI's minerals, mining and metallurgy director.

  • Scientists today announced that the Rising Star Cave system has revealed yet more important discoveries, only a year and a half after it was announced that the richest fossil hominin site in Africa had been discovered, and that it contained a new hominin species named Homo naledi by the scientists who described it. [...]

    Direct dating of the teeth of Homo naledi, using Uranium series dating (U-series) and electron spin resonance dating (ESR), provided the final age range. "We used double blinds wherever possible," says Professor Jan Kramers of the University of Johannesburg, a uranium dating specialist. Dr. Hannah Hilbert-Wolf, a geologist from James Cook University who also worked on the Dinaledi Chamber, noted that it was crucial to figure out how the sediments within the Dinaledi Chamber are layered, in order to build a framework for understanding all of the dates obtained.

  • Pipestone Vineyards recently sold its west Paso Robles property, but the label will carry on, owner Jeff Pipes said.

    The winery, begun by Pipes and his wife, Florence, in 1996, still has two vintages of Pipestone wine aging in barrels and is looking to start sourcing other westside fruit to carry them forward, he said.

    The family will make future vintages at a custom crush facility and sell its wine mostly through its wine club, telephone and website sales, aiming to keep production at about 1,500 to 2,000 cases per year.

  • Today, a massive sheet of ice covers nearly all of West Antarctica, but it likely hasn’t always been that way.

    Over the past few hundred thousand years, researchers think that the ice sheets have waxed and waned, varying in size as the region’s climate changed. As they fluctuated, the ice sheets would have captured so much frozen water that sea levels around the world would have risen and dropped accordingly. [...]

    To gather hard geologic evidence of how dynamic the ice cover has been in the past, and may be in the future, John Stone of the University of Washington and his team traveled to a remote region of the continent this past season. [...]

    “Our knowledge of the subglacial geology and where different rock types are is not excellent over Antarctica,” said Perry Spector, also at the University of Washington. “So the fact that we’re right next to a mountain, a nunatak of granite, means that if we go just a little bit off board of there and drill down, we’re almost guaranteed to hit granite.” [...]

    Collectively, these samples will give researchers a comprehensive picture of the ice sheet over thousands of years.

    “The ones below the ice sheet can tell us information about if and when the ice has been thinner there, but the ones above the modern ice level can tell you information about if and when the ice was thicker in the past,” Spector said. “You can get information about both times when the West Antarctic ice sheet was thicker and more extensive than it is now, as well as information about if and when it was thinner and less extensive.”

  • California’s landmark effort to value distributed energy resources by their location on the grid appears to be running into speed bumps. 

    If there’s one thing the parties in the state’s locational net benefit analysis (LNBA) working group can agree on, it’s that the valuation tool they have developed is “not yet ready” and “needs refinements.”

    The report does not discourage Marc Monbouquette, senior regulatory analyst for the California Public Utilities Commission (CPUC). 

    “This start gives the commission plenty to work with because it shows what the tool can and cannot do and we know where it needs to go," he told Utility Dive.

  • Hawaii is known for its volcanoes, but most volcanoes on earth exist along tectonic plate lines. Hawaii does not! What causes Hawaii to form, and how is it related to the mystery of a magnetic bar code across the Pacific Ocean? Host Dianna Cowern chatted with geologist Noah Randolph-Flagg from UC Berkeley while hiking on the island of Kauai.
