X-ray study reveals new details of how burrowing sea creatures shape geology
SLAC National Accelerator Laboratory via Newswise
Research at the Department of Energy's SLAC National Accelerator Laboratory reveals new details about how tiny, burrowing sea organisms can influence the chemistry and structure of rocks where hydrocarbon deposits such as oil and gas are found. An international team of scientists used X-rays to image the chemistry of rock samples containing well-preserved 80-million-year-old fossilized burrows, which may have been made by millimeter-sized bristly worms known as polychaetes.

Mound near lunar south pole formed by unique volcanic process
Phys.org
A giant mound near the moon's south pole appears to be a volcanic structure unlike any other found on the lunar surface, according to new research by Brown University geologists. The formation, known as Mafic Mound, stands about 800 meters tall and 75 kilometers across, smack in the middle of a giant impact crater known as the South Pole-Aitken Basin. This new study suggests that the mound is the result of a unique kind of volcanic activity set in motion by the colossal impact that formed the basin.

Anatomy of an 'Ice Station'
Phys.org
Completing an "Ice Station" means collecting samples over a wide range of Arctic water and ice conditions. Each station means a major orchestration of people and resources. The teams gather, equipment is assembled, and the trek off the ship begins. After the first off-ship exodus, the sample teams are well practiced in moving equipment and setting up work areas so as not to interfere with the other stations.

AIPG New England Aquifers: Elusive and Complex Conference — Earn 4 Contact Hours or .4 CEU's; Earn 2 LSP Technical Credits
AIPG
This is a half-day workshop was developed to provide water utility personnel, engineers, hydrogeologists, regulatory officials and other interested persons in understanding about the sand and gravel and bedrock aquifers their wells are located in and how and why well performance declines over time along with options that are available to rehabilitate your well. The workshop begins with an introduction of the geology and aquifers of New England. From plate tectonics to glacial geology along the effects of weathering that have created the majority of high-yield aquifers located throughout New England. A quick trip through well types, water well terminology, groundwater flow into well screens and a discussion of specific capacity as it applies to sand and gravel and bedrock aquifers. Specific capacity is easy to calculate and use as a measure of the performance of your well, but something that is often overlooked. Moving forward, there is a segment on declining well performance including a discussion of the chemical, physical, and microbiological factors that are the cause for drop in performance in wells. Improving the performance of your well will be discussed by examining physical and chemical methods to rehabilitate your well and improve specific capacity. Understanding the permitting considerations along with the costs of well rehabilitation services will be discussed. The final segment of the workshop will be case studies on well rehabilitation. This will tie together all of the other segments of the workshop.

Climate cycles didn't shape ocean's abyssal hills
Science
Earlier this year, a pair of papers suggested that long-term cycles of glaciation and melting trigger pulses of lava that harden into sea floor hills. But now, a new study throws cold water on that hypothesis, finding that these climate-driven pulses did not significantly shape the sea floor. Instead, they say, the underwater hills likely come from faulting action and steady — rather than climate-driven — magma eruptions.

Holes in Indiana Dunes' Mount Baldy likely caused by buried 'ghost forest'
The Associated Press via Chicago Sun-Times
Trees slowly buried by windblown sand are likely the root cause of dangerous holes that have appeared in the towering Mount Baldy sand dune in the Indiana Dunes National Lakeshore, a geologist says. Erin Argyilan believes pockets were formed around tree branches and trunks enveloped by Mount Baldy. She says that created a "ghost forest" beneath the sand.

Glacier was once Yosemite's largest; now it's almost gone
San Francisco Chronicle
The Lyell Glacier, once estimated as a mile wide and Yosemite’s largest glacier when visited by John Muir in 1872, could melt and disappear in as soon as five years, according to park geologist Greg Stock, if warm temperatures at high elevations continue. The glacier has lost about 90 percent of its volume and 80 percent of its surface area from 1883 to 2015, according to Stock and Peter Devine, a naturalist with the Yosemite Conservancy who has studied the Lyell Glacier for 30 years.

International experiment tracks underwater avalanches in Monterey Canyon
KSBW-TV
Underwater avalanches and turbidity currents carry huge amounts of sediment, organic material and pollutants down submarine canyons and into the deep sea. Yet geologists know very little about how sediment moves during these events. This month, in what may be the most ambitious submarine-canyon study ever attempted, marine geologists from several countries are placing dozens of sophisticated instruments in Monterey Canyon. This international effort promises to give scientists a uniquely detailed and comprehensive view of sediment movement within the canyon.

Warming Arctic could uncover Alaska Native artifacts
The Associated Press via The Washington Times
A researcher at the University of Alaska Fairbanks is attempting to predict where higher Arctic temperatures will melt snow to uncover ancient Native Alaskan artifacts. Perennial, stationary snow patches on the Brooks Range that accumulated over thousands of years are expected to deteriorate as the Arctic warms at double the global average. Caribou migrations indicate hunting artifacts, clothing and tools may be beneath the snow. Snow hydrology graduate researcher Molly Tedesche is trying to predict where these fragile items will be before they decay from exposure to the elements.

Cuban oil: Black gold or black hole?
Fox Business
Cuba has oil and gas. That is certain, say geologists. The big question is just how much. Chris Schenk, geologist at the U.S. Geological Survey, was one of the first to assess the island's natural resources. By Schenk's estimate, Cuba has at least 4.6 billion barrels of undiscovered oil and 9.8 trillion cubic feet of undiscovered natural gas. Both are considered significant enough to pique the interest of any major energy company in the world.
