Shoup Glacier, Alaska Retreat, Thinning, Velocity Decline

Fri, 02/24/2017 - 12:34pm
Shoup Glacier comparison in 1986 and 2016 Landsat images.  The glacier retreated 1900 m in this interval.  Red arrow is 1986 terminus, yellow arrow the 2016 terminus, green arrow rock rib emerging from beneath glacier, purple dots a landslide deposit, and purple arrow the snowline. Shoup Glacier is between the Columbia Glacier and Valdez draining from the Chugach Mountains in southern Alaska.  The glacier was a tidewater terminating glacier until …

(Geo)science Matters: Snow surveys aren’t just for TV

Fri, 02/24/2017 - 12:01pm
Everyone (in California, at least) has seen those clips that get run every winter of the snow surveys: people walking out into a white-blanketed meadow to shove a pole into the snow and record the depth. Or, in the case of the 2015 broadcast, walking out onto muddy grass and gesturing sadly at a lack of snow in which to do this. It's a good photo op, but the broadcasts rarely follow up with much of the science behind the survey.

Are we living in a warm peak between ice ages?

Fri, 02/24/2017 - 10:04am
By Ned Rozell As another major rainstorm hit California in February, downtown San Francisco surpassed its normal rain total for an entire year. Reservoirs in the high country were spilling over. So ended a five-year drought in the state that some people attributed to human-caused climate change. Those pictures of dried-up California lakes bothered Syun-Ichi Akasofu, who recently gave a talk “The Forthcoming Ice Age” at the University of Alaska …

The Magic of Reality, by Richard Dawkins

Wed, 02/22/2017 - 8:27am
I just finished Richard Dawkins’ book for younger readers and/or a general audience, The Magic of Reality. It’s a general-interest science education book, written in Dawkins-speak – very conversational and emphatic about key points. It consists of a series of chapters about different topics, with each chapter guided by a big question, like “What is a rainbow?” or “What are things made of?” or “Who was the first person?” Dawkins …

The 170 km/h Sanxicun landslide in Sichuan Province, China

Sol 1618: A second stop at the dunes

Wed, 02/22/2017 - 2:00am
By Lauren Edgar The drive on Sol 1617 went well, and Curiosity drove 20 m to the south, which put us in a good position for another stop at the Bagnold Dunes.  This site was selected to enable comparison of the leading and trailing edges of the dunes.  Today’s plan includes ChemCam observations of disturbed and undisturbed soil, at targets named “Tomhegan” and “Macworth.”  We’ll also acquire a Mastcam multispectral …

Sol 1617: Re-attempt the drive

Wed, 02/22/2017 - 2:00am
The drive planned for Sol 1616 halted early, apparently because the right rear wheel got stuck between two rocks. The mobility team concluded that it is safe to continue, so the drive planned for Sol 1617 is essentially the same as the previously-planned drive. Before the drive, ChemCam and Right Mastcam will observe a sand target named “New Sweden” and Right Mastcam will acquire mosaics of a layered bedrock outcrop …

Sulmeneva Glacier Retreat from Lakes, Novaya Zemlya

Sulmeneva Glacier retreat in comparison of 1999 and 2016 Landsat images. Red arrow indicate the 1999 terminus position and yellow arrows 2016 terminus location.  Sulmeneva Bay is on the west coast of Novaya Zemlya and is the southern most extent of the continuous glaciation that extends along the northern half of the island.  Here we examine an unnamed glaciers that terminates in a piedmont lobe near the shore of Sulmeneva Bay. The …
