Northern wheatears now on remarkable journey
Birds that spent their summer next to muskoxen are now leaving Alaska to spend winter with zebras.... Wheatears are now gobbling insects in the rocky hills above Wales, Alaska. The birds will soon fly into the moist air just after sunset, maybe tonight, and cross the Bering Strait.

Friday fold: crumpled green metavolcanics from St. Anthony
The Friday fold erupted out of a volcano, completing the second part of its two stage cooling history, then later got folded and metamorphosed. It was found atop a high cliff near the northern Newfoundland town of St. Anthony.

Sols 2489-2491: A Change in the Weather (Observations)
Over the weekend, Curiosity successfully dropped off a portion of the Glen Etive drill sample. But for some reason, the sequence was interrupted, so no images of the portion were acquired.

Ten Years of Icy Data Show the Flow of Heat from the Arctic Seafloor
Scientists have taken the temperature of a huge expanse of seafloor in the Arctic Ocean. The study is accompanied by the release of a large marine heat flow dataset collected by the USGS from an ice island drifting in the Arctic Ocean between 1963 and 1973. These never-before-published data greatly expand the number of marine heat flow measurements in the high Arctic Ocean.

The Benefits of Attending Conferences
Although young researchers might feel intimidated by conferences and presenting research for the first time, conferences provide a significant amount of professional and personal development, which makes them an extremely valuable experience. Communicating research in a concise and engaging way can be challenging, especially for less experienced researchers. Presenting at a conference allows young researchers to refine their communication skills. Researchers can practice presenting to an audience and receive immediate feedback …

More intense non-tropical storms causing increased rainfall in Southeast U.S.
A new study in AGU’s journal Geophysical Research Letters examined the region’s precipitation records from 1895 to 2018. The new research found precipitation in the Southeast during the fall increased by almost 40 percent in the past century due to an increase in average daily rainfall rather than the overall number of storms.

Moonquakes tumble boulders, build lunar scarps
The Apollo Moon buggies weren't the only things rolling over the Moon's surface in the early 1970s. New research has found that a strong moonquake in 1975 probably sent boulders tumbling down crater walls on our nearest neighbor.

How the Pacific Ocean influences long-term drought in the Southwestern U.S.
New research explores what conditions in the ocean and in the atmosphere prolong droughts in the Southwestern U.S. The answer is complex, according to a study published Aug. 6 in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union.

New study traces Io’s volcanic tides
Hundreds of volcanoes pockmark the surface of Io, the third largest of Jupiter’s 78 known moons, and the only body in our solar system other than Earth where widespread volcanism can be observed. A new study finds Io’s most powerful, persistent volcano, Loki Patera, brightens on a similar timescale to slight perturbations in Io’s orbit caused by Jupiter’s other moons, which repeat on an approximately 500-Earth-day cycle.

Geoengineering versus a volcano
Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun’s radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new paper in the AGU journal Geophysical Research Letters investigates.

Toreva Block landslide models
Somewhere on the AGU Landslide blog, I came across a reference to another type of rock strength-controlled, intact landslide I had never heard of–the Toreva Block. Like the Appalachian Valley and Ridge giant landslides, it is possible to replicate Toreva-style movement with contrasting model materials that represent failure-prone shale and much stronger topography-supporting lithologies, like sandstone or basalt.

E20 – Ballooning on Venus
Venus, Earth’s nearest planetary neighbor, is a rocky world close in size to our own. In our solar system, it is the planet most like Earth. But Earth and Venus have taken different developmental paths, creating curious contrasts for scientists interested in planetary evolution.

Icelandic glaciologist feels a weighty responsibility
Icelanders will soon install a plaque they hope people will read, long after those who bolted it to a mountain are dead. Near a withering glacier, the sign reads: Ok (Okjökull) is the first Icelandic glacier to lose its status as a glacier.
