Sol 1501: Welcome to Bar Harbor

Tue, 10/25/2016 - 11:00pm
Prior to landing we divided up the landing ellipse and nearby areas into square quads (1.5 km on a side), and assigned each quad a name of a town with a population of less than 100,000 people.

Ross Ice Shelf Shear Zone-Research Focus of Gordon Hamilton

Tue, 10/25/2016 - 1:15pm
Satellite Image of the Shear Zone:  The crevasses do have a surface representation, but are not generally open.  Gordon Hamilton lost his life on Saturday Oct. 22, 2016 conducting research in the shear zone between the Ross Ice Shelf and McMurdo Ice Shelf.  I had the pleasure of working with and reviewing Gordon’s work; hence, it seems important to elaborate on the research that had brought researchers to this cold …

Today’s plan is focused on targeted remote sensing and driving. The morning science block includes ChemCam observations on the targets “Ranaka” and “Seleka” to assess the composition of the local bedrock.

GIGAmacro views of komatiite

Mon, 10/24/2016 - 1:11pm
Erik Klemetti posted today at Eruptions about komatiite, which is apropos, considering I just finished imaging some samples of that ultramafic volcanic rock. Have a look at three samples from Barberton Greenstone Belt here, each from the 3.27 Ga Weltevreden Formation: [gigapan src=”,hidetitle/iframe/flash.html” height=”250″ scrolling=”no” width=”100%”] Link GigaPan by Callan Bentley [gigapan src=”,hidetitle/iframe/flash.html” height=”250″ scrolling=”no” width=”100%”] Link GigaPan by Callan Bentley [gigapan src=”,hidetitle/iframe/flash.html” height=”250″ scrolling=”no” width=”100%”] Link GigaPan by Callan …

Ísland: Floods

Sat, 10/22/2016 - 6:00am
When you bring together volcanoes and ice - as many places in Iceland do - you get floods. Specifically, they're called jökulhlaups, which literally means "glacier run" but in reality means a glacial outburst flood. Originally the term was used for subglacial outburst floods from Vatnajökull ice cap, which covers the Grímsvötn and Öræfajökull volcanoes, but it's come to mean any large, abrupt release of water from under a glacier or from a lake at the glacier front.

Tasermiut Fjord, Greenland loses its Glacier Connection

Fri, 10/21/2016 - 11:54am
  Landsat image sequence from 1999-2016.  Red arrows mark the 1999 terminus, yellow arrows the 2016 terminus and the purple arrow a tributary that detaches from Semitsiaq (S). Tasermiut Sermeq (T) retreats from the fjord.  Tasermuit Fjord in southern Greenland is noted for its beauty, and until recently the fjord terminated at a glacier front. Currently no glacier reaches to the fjord. The retreat over the last two decades is …

Friday fold: a miniature ramp and flat

Fri, 10/21/2016 - 9:18am
Sometimes you find big ideas in small places. Here, a South African chert boulder mimics in miniature fold and thrust belts the world over.

Life on barrier islands, north and south

Fri, 10/21/2016 - 5:00am
There are connections between the Deep South and Far North: some of the shorebirds probing the beach on the Gulf of Mexico emerged from eggs this summer on northern tundra. The tankers sitting just offshore awaiting transit to Houston are filled with the same liquid that fuels the Alaska economy. And this barrier island 27 miles long and two miles wide is at constant risk of being hammered by a storm.

The Aberfan victims and survivors

Fri, 10/21/2016 - 3:41am
The Aberfan victims and survivors Today is the 50th anniversary of Aberfan, an event that will be commemorated both at the site and across the United Kingdom.  It is of course a day to remember the Aberfan victims, the majority of whom were children and teachers at the Pantglas Junior School, and to hear accounts of the survivors.  Those lost are remembered in a simple memorial garden at Aberfan, with …

The Aberfan tragedy – what happened next?

Thu, 10/20/2016 - 3:35am

In this video continental crust is first pulled apart during extension and then tectonic forces change direction and the crust is put under compression. What results is first a basin and then an inverted basin.

Oddball Icelandic rocks, part III: conglomerate

Wed, 10/19/2016 - 7:25am
At the Volcano Museum in Stykkishólmur, I learned that Iceland has fossils. Specifically, they have a display of bivalve (clam) fossils there, and when I asked where to find them, I was directed to a point further east on the Snæfellsnes Peninsula. The next day, I set off to find them. Here was what I saw on a cliff high above me, at the spot nearest to where I thought …
