NEWSBREAKERS
Europe's 'Landsat' scheduled for launch
Sentinel-2a is set for launch on June 12. It will image the Earth in visible and infrared light and will be used to track surface changes over time. Imaging will be sensitive across 13 multispectral bands and it will map swaths 290km wide with colour images having a 10m resolution. Sentinel-2b will be launched in 2016.

Invitation to attend the Geological Society of America Penrose Conference
The Geological Society of America has formally invited GSA members to apply to attend the upcoming Penrose Conference, June 22 - 27. The conference title is: Extensional Reactivation of Thrust Faults, Coseismic Surface Rupture, and Crustal Evolution in the Eastern Basin and Range Transition Zone Evanston, Wyoming.
The conference will address active (Pleistocene to late Holocene) extensional tectonics overprinted on preexisting Sevier and Laramide structures, tectonic geomorphology, earthquake hazard/risk, neotectonic effects on hydrocarbon occurrence, and crustal evolution in the eastern Basin and Range transition zone however it is limited to a maximum of 80 attendees.
An application form is available on the Penrose Conference website. The application form or, alternatively, an email containing the requested information should be received by the Conference Chairman not later than March 13, 2015.
Successful applicants will be notified by return email not later than April 24, 2015. Registration materials will be forwarded to Conference attendees by April 1, and should be completed and returned to GSA, by May 1, 2015.

IN THE NEWS
Gold bubbles up?
Recent research in Australia and Canada has found that gold, copper, nickel and platinum bind to molten iron sulphide. The sulphides can be rafted to the top of the magma chamber by vapour bubbles where relatively shallow ore bodies can form. In addition this mechanism could explain the high levels of sulphur brought to the surface by some volcanoes.

Copper and volcanism model to help exploration
A model to explain the association of copper ore deposits with volcanism suggests salt-rich fluids separate from large magma bodies and become trapped in the crust at a depth of a few kilometres. It is proposed these brines have the ability to concentrate copper from the magma from which they separate and, at a later stage, sulphur-rich gases ascend from deeper in the same volcanic system where they react with the trapped, copper-rich brines explosively to form sulphide ores and hydrogen chloride gas. Experimental results indicate this fully explains copper porphyry systems and will help future copper exploration in these terrains.

An inner inner core?
New methods of seismic data analysis suggest Earth's inner core has a distinct inner core of its own. It appears iron crystals in the outer layer of the inner core are aligned north-south while the inner-inner core iron crystals point roughly east-west. This may mean materials in this inner-inner zone exists in a different crystalline phase that is yet to be understood.

When is an eruption just water?
A rare sub-glacial water eruption, otherwise known as a Jökulhlaup, near Australia's Casey station, may reveal why meltwater is present, and the extent the system flowing under the Law Dome ice cap. It is only the second reported event of its type in Antarctica. The age, chemistry and origins of the refrozen water is now under investigation.

Geoventure participants up close and personal with a volcano
In February, Students and Graduates from the University of Wollongong, Australian National University, Macquarie University, Linwood College and the University of Canterbury (New Zealand) and a research assistant from NASA Ames Research Centre descended on the Big Island of Hawaii to learn about volcanism from Gary Lewis (GSAmerica). Here is a snapshot of their field experience. This trip will be running again February 2016, for more information contact Gary: glewis@geosociety.org.

IN THE MEDIA
Hydrogen sulphide upwelling, no volcano required
In Africa, easterly winds push surface waters offshore and promote upwelling near the Namibian coast. Anoxic bacteria in the bottom waters produce hydrogen sulphide that is drawn up into the oxygen rich surface zone where the sulphur precipitates out and floats near the surface to create a plume visible from satellite.

New Ichthyosaur species found in a museum cupboard
A new Ichthyosaur has been found in storage at a museum in Doncaster, England. The fossil was so well preserved the stomach contents could be identified as the hooks from the tentacles of squid. The new species, Ichthyosaurus anningae, is named in honour of Mary Anning who discovered the first Ichthyosaur in 1811.

Yet another hole in Mars
This drill hole at Telegraph Peak is located in the upper portion of Pahrump Hills, an area where two other drill holes have been sunk. The outcrop is an exposure of bedrock that forms the basal layer of Mount Sharp. Next stop is a narrow valley called Artist's Drive, which will lead the rover along a strategically planned route higher on the basal layer of Mount Sharp.
