[IPRNmail] Call for participation in a new APECS initiative: Arctic Snapshots

Check it out! A very interesting and exciting new initiative by APECS!

Call for interest in new APECS event:
"Arctic Snapshots" webinar between two field stations during 2015 field season.

We're organizing participants for an exciting new concept aimed at promoting the excitement of scientific research. The concept, which we're calling "Arctic Snapshots", will be an online webinar between scientists (both young and senior) at two field stations in similar disciplines of arctic science. This will take the format of a 1.5 hour webinar between two field stations during the Summer 2015 field season.

The main objectives of Arctic Snapshots are: (i) for scientists to share the excitement of their research; (ii) to promote increased networking between young and senior scientists (and potential future educational opportunities or research collaborations); (iii) for participants - particularly young scientists - to gain invaluable experience presenting their summer work.

The presentation format will be an 8-minute "pitch" aimed at facilitating critical thought and communication about the relevance of the presenter's research. Presentations can include research methods, findings, or an introduction to the presenter's research project. Arctic Snapshots will connect two research stations, with 5 presentations per field station, totaling to 40 minutes of presentations for each station (excluding a ~5 minute question period).

We are currently recruiting interested participants to represent their field station and to help us plan the event. If you're interested, or know an organization that might be, please send me the following information at zolkos@ualberta.ca:

1. Your name and the field station with which you are connected
2. The field station's location, website (if applicable), and which season(s) the field station is operating
3. The field station's internet connectivity (e.g. capable of a Skype call?)

We hope you're interested and look forward to your participation in this exciting event.


Best Regards,

Archana.

[IPRNmail] Lake Vostok breakthrough: Russian scientists drill ‘clean’ hole into Antarctic subglacial basin


Russian scientists have made a new borehole into Lake Vostok, the prehistoric Antarctic water mass, which has been sealed for millions of years â€" three years after a previous mission was prematurely ended by an accident resulting in sample contamination.

“This is an event of worldwide significance, which has huge scientific value,†said Russia’s environment and mineral resources minister Sergey Donskoy, as the expedition hit the water surface at the depth of 3,769 meters and 15 cm.

The surface of the lake â€" now listed as the sixth biggest in the world and biggest in Antarctica â€" had been undisturbed by sunlight for over 15 million years, before it was reached by a Russian drilling team during the Antarctic summer three years ago.

READ MORE: Lake Vostok mysteries: Biologists find over 3,500 life forms in isolated Antarctic basin

Scientists are hoping to find life forms in the pristine cold water â€" twice as pure as double distilled mineral water â€" that have no equivalent on Earth, but may exist somewhere else in the universe.

This Earth reservoir is a perfect dry run for searching for life forms in space, because we believe the most promising life forms exist where there is water, including the Jupiter satellite Europa,†expedition head Valeriy Lukin told the St.Petersburg Vestnik newspaper ahead of the borehole completion. “Even if we find no life there at all, this will also be a significant discovery, showing that conditions that are totally unsuitable for life do exist.â€

The previous drill-through to the surface of the water, which is around -3 degrees celsius but does not freeze due to pressure, was hailed as one of the biggest geological discoveries on Earth, making the world media swoon. But the scientific results produced from that mission were negligible, due to an accident that set the team’s work back by years.

READ MORE: Cool Find: Russian team takes ice from biggest Antarctic sub-glacial lake, searching for life

When the drill bit reached the water in February 2012, the pressure made it shoot up hundreds of meters, mixing it up with the Freon and kerosene used to keep the borehole from freezing. Worse than that, in an unintended imitation of modern drilling methods, the pressure produced a hydraulic fracture about 3,300 meters from the well entrance. The anti-freeze agents seeped into the ice, while the rest of the borehole below them quickly froze.

Although samples taken from the water in the lake showed thousands of life forms, no one could guarantee that it was free of contamination.
--
So, for the last three years, the Russian team has been re-drilling those last 500 meters, through a parallel borehole.

“We are doing everything to avoid repeating the mistakes of the past,†said Lukin, who noted that this time scientists have a clearer idea of where the water surface is located. “But we are also more ambitious â€" we do not only plan to take water from the surface, but also from the water deeper inside the lake.â€

To this end, a special 50 kg probe has been developed, which ensures that the collected water â€" up to 1 liter in volume â€" is not adulterated by the antifreezing agents.

And how soon will the world know if there really are alien life forms teeming below the surface?

“We will need many years to fully interpret what we find, and a measured progress stretching seasons as we go deeper and deeper into the water mass,†says Lukin.

[IPRNmail] Robot finds fish beneath Antarctic ice, could be used to explore Europa


Robot finds fish beneath Antarctic ice, could be used to explore Europa

http://www.engadget.com/2015/01/26/robot-antarctica-fish-europa/

When a group of scientists drilled through 2,430 feet of ice in Antarctica to get to the water underneath, they only expected to find a few microbes here and there. Instead, they discovered a thriving community of fish and crustaceans -- all thanks to a remote-controlled robot that could one day also be used to explore one of Jupiter's moon. It took the tubular robot called Deep-SCINI (Submersible Capable of under Ice Navigation and Imaging) 45 minutes just to traverse the hole made by pumping hot water through the Ross Ice Shelf. It eventually settled three feet above the very bottom, where up to 20 and 30 fish swam close to gaze at its lights.

[IPRNmail] Warm ocean melting East Antarctica's largest glacier


Warm ocean melting East Antarctica's largest glacier

Sydney (AFP) - The largest glacier in East Antarctica, containing ice equivalent to a six-metre (20-foot) rise in global sea levels, is melting due to warm ocean water, Australian scientists said on Monday.

The 120-kilometre (74.4 mile) long Totten Glacier, which is more than 30 kilometres wide, had been thought to be in an area untouched by warmer currents.

But a just-returned voyage to the frozen region found the waters around the glacier were warmer than expected and likely melting the ice from below.

"We knew that the glacier was thinning from the satellite data, and we didn't know why," the voyage's chief scientist Steve Rintoul told AFP.

He said that up until recently the East Antarctica ice sheet had been thought surrounded by cold waters and therefore very stable and unlikely to change much.

But the voyage found that waters around the glacier were some 1.5 degrees Celsius warmer than other areas visited on the same trip during the southern hemisphere summer.

"We made it to the front of the glacier and we measured temperatures that were warm enough to drive significant melt," Rintoul said.

"And so the fact that warm water can reach this glacier is a sign that East Antarctica is potentially more vulnerable to changes in the ocean driven by climate change than we used to think."

Previous expeditions had been unable to get close to the glacier due to heavy ice, but Rintoul said the weather had held for the Aurora Australis icebreaker and a team of scientists and technicians from the Australian Antarctic Division and other bodies.

Rintoul said the glacier was not about to melt entirely overnight and cause a six-metre rise in sea levels, but the research was important as scientists try to predict how changes in ocean temperatures will impact on ice sheets.

"This study is a step towards better understanding of exactly which parts of the ice sheets are vulnerable to ocean warming and that is the sort of information that we can then use to improve our predictions of future sea level rises," he said.

"East Antarctica is not as protected from change as we use to think," he said.

The melt rate of glaciers in the fastest-melting part of Antarctica has tripled over the past decade, analysis of the past 21 years showed, according to research published last month.

[IPRNmail] UPDATE: http://en.mercopress.com/2015/01/26/state-of-the-art-polar-vessel-for-bas-to-be-delivered-in-2019


State of the art polar vessel for BAS to be delivered in 2019

A new polar research vessel is currently being designed for the British Antarctic Survey (BAS). The new vessel will be an ice-capable, multi-role polar research and logistics ship which will be used to conduct science and to resupply the BAS stations such as the two in South Georgia, according to the latest South Georgia Newsletter.


A concept design for the new polar vessel, provided by Houlder Ltd naval architects, has been prepared. The ship’s features will include the ability to carry helicopters and a scientific moon pool. It is expected to be built and ready for operation in late 2019. The new ship will replace both of the current BAS vessels RRS James Clark Ross (JCR) and RRS Ernest Shackleton.

The new vessel was announced by BAS parent organization the Natural Environment Research Council (NERC) in April 2014. They are now consulting with potential users to assist in the design phase to ensure that the vessel meets the current and future needs of the science community. Consulting is being conducted both online and at a meeting in London.

NERC have invited the UK and international marine and polar science user community to submit comments on the vessel's design. The London meeting will be a on January 15th to engage with the wider scientific community and encourage further participation and input into the vessel's overall design concept and operability.

Funding of more than £200 million has been earmarked for the new ship and associated enabling works at the UK's Antarctic research stations. According to the NERC website, “The state-of-the-art polar research vessel should ensure that UK polar scientists remain at the forefront of environmental research in both the Antarctic and the Arctic.â€

[IPRNmail] UC Santa Cruz scientists drill through ice into a new Antarctic world


UC Santa Cruz scientists drill through ice into a new Antarctic world

WWW.nta-cruz-scientists-drill-through-ice-into-a-new-antarctic-world


SANTA CRUZ >> Early in January, a jet of hot water broke through the last meter of ice in Antarctica’s largest ice shelf, opening a passageway into an unknown world.

The jet was from a specially designed hot water drill, controlled by scientists half a mile above. Thus began a 10-day rush to gather as much data as possible before the hole in the ice froze shut, said Slawek Tulaczyk, a UC Santa Cruz professor and the project’s lead glaciologist.

This is the first time humans have accessed an ice shelf’s “grounding zone,†a region crucial to understanding the effects of climate change on Antarctic ice.

The Ross Ice Shelf is a slab of ice about the size of Texas that extends from Antarctica more than 500 miles over the open ocean. Where the ice separates from the Antarctic land mass, there is a wedge of water known as the “grounding zone†between the ice and the sea floor.

Scientists believe that warm ocean currents are melting ice shelves from underneath and pushing grounding zones inland, Tulaczyk said. But until now, no one has taken measurements from the point where water, earth, and ice all meet.

When the researchers sent down a robot with a camera Jan. 16, they were amazed to see fish, crustaceans and other complex animals. The sliver of water, just 10 meters deep, between the ice and the sea floor, receives few nutrients and no sunlight, Tulaczyk said.

Confident they would find only microscopic life in this harsh environment, the team did not even recruit anyone who studies larger life forms.

“It seems to be a place that has quite a vibrant ecosystem, and that is surprising,†Tulaczyk said.

The current expedition is part of the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project, a collaboration of investigators at several institutions. In previous years, WISSARD has drilled into parts of the ice sheet that rest directly on bedrock in order to study how ice flows toward the ocean, said Dan Sampson, an instrumentation engineer at UCSC who designs and builds instruments for the project.

This year, the team drilled two holes through nearly 2,500 feet of ice to reach liquid water.

The larger hole, about two feet in diameter, allowed the researchers to lower and retrieve bulky instruments and collect samples of sediment, Tulaczyk said. The smaller hole was for a string of instruments from UCSC that will remain in the ice after the hole closes, broadcasting measurements about factors such as tilt, pressure and temperature. A few of the instruments have failed, but that, said Sampson, is to be expected.

“We instrumented the heck out of that hole,†said Sampson. “It would have been awesome if everything worked perfectly, but any data we get is going to be incredible.â€

The data will help researchers understand how warm ocean water is eating away at Antarctic ice, and it may help them predict future rises in sea level, Tulaczyk said.

“We are shining a light on the very processes that will determine how sea levels will change in the future, in a place where it’s really really difficult to access and study,†Tulaczyk said. “We’ve managed to shine that light there for the first time.â€

[IPRNmail] Environmental data analyst for the BOUSSOLE bio-optics time series


Environmental data analyst for the BOUSSOLE bio-optics time series

 

The BOUSSOLE project seeks applicants for a 2-year position, with a start as soon as possible. The position is proposed at the Laboratoire d'Océanographie de Villefranche (LOV) within the Marine Optics, Ocean Colour Remote Sensing and Marine Biogeochemistry (OMTAB) group (http://www.lov.obs-vlfr.fr/en/the_laboratory/research_groups/omtab_group.html)

 

The goals of the BOUSSOLE project are fundamental research in bio-optics and calibration/validation of satellite ocean colour observations. The project started in 2000 and has built (and continues to build) a unique data set of inherent and apparent optical properties plus biogeochemical properties in the North-western Mediterranean Sea. These data are collected from an offshore mooring and during monthly cruises to the mooring site. BOUSSOLE is funded by the European Space Agency (ESA), the National French Space Agency (CNES), and the French National Scientific Research Institute, CNRS/INSU. See at http://www.obs-vlfr.fr/Boussole.

 

The applicants are expected to work on the assessment of the error (uncertainty) budget for the radiometry measurements performed on the mooring, in particular by working on the identification and quantification of uncertainties associated to measurement of radiometric quantities (radiance and irradiance) and their propagation to the ocean colour products (e.g., remote sensing reflectance and diffuse attenuation coefficients). This work will be carried out in collaboration with the BOUSSOLE staff and the UK National Physical Laboratory (NPL). NPL is indeed engaged with LOV in improving calibration of BOUSSOLE radiometers and in establishing a full error budget of radiometry measurements. Other research topics related to the BOUSSOLE objectives, and to be developed in parallel to the main activity described here, will be possibly discussed with the project PI.

 

Applicants should be suitably qualified (Ph.D level) in oceanography with a background in marine optics, and should have the necessary experience in data processing. Some background in theory of measurements and errors and in statistical analyses is required.

Capabilities to conduct radiometric work in the laboratory and fieldwork would be appreciated but are not essential. Either French or English are appropriate as working languages.

 

The annual salary will depend on the level of experience of the candidate. The laboratory is located in Villefranche-sur-mer, near Nice on the French Riviera. The position will start for a year, renewable in case the candidate and the project PI are willing to do so (can expand up to four years, funding permitting).

 

CVs and covering letters, as well as requests for additional information, are to be sent to the project manager Vincenzo Vellucci (enzo@obs-vlfr.fr, with "Boussole-Position" in the subject line), with copy to the project PI, David Antoine (antoine@obs-vlfr.fr). Deadline for applications is 8 March 2015.

[IPRNmail] Sc-Hidden magnetic messages found in meteorites


Hidden magnetic messages found in meteorites


The team led by Richard Harrison captured information stored inside tiny magnetic regions in meteorite samples using the dedicated photo-electron emission microscope (PEEM)-Beamline at BESSY II, a research establishment in the Adlershof district of Berlin, Germany.

This information provides a sneak preview of the fate of the Earth's own magnetic field as its core continues to freeze.

Harrison identified specific regions filled with nanoparticles that were magnetically extremely stable.

These "tiny space magnets" retain a faithful record of the magnetic fields generated by the meteorite's parent body.

Harrison and PhD student James Bryson found dramatic variation in magnetic properties as they went through the meteorite.

They saw not only regions containing large, mobile magnetic domains, but also identified an unusual region called the cloudy zone containing thousands of tiny particles of tetrataenite, a super hard magnetic material.

"These tiny particles, just 50 to 100 nanometres in diameter, hold on to their magnetic signal and do not change. So it is only these very small regions of chaotic looking magnetisation that contain the information we want," Bryson added.

The observations demonstrate that the magnetic field was created by compositional, rather than thermal convection.

"This changes our perspective on the way magnetic fields were generated during the early solar system," Harrison concluded.

Their results were published in the journal Nature.

[IPRNmail] Fwd: Solar news : Don't miss 100 millionth photo of the Sun


Don't miss 100 millionth photo of the Sun

ashington: NASA's Solar Dynamics Observatory has released a mind-boggling 100 millionth photo of the Sun for public viewing.

Using its Advanced Imaging Assembly (AIA) instrument, the space-based Sun-watching observatory hit the photo milestone Jan 19, the US space agency said in a statement.

The AIA uses four telescopes working parallel to gather eight images of the sun - cycling through 10 different wavelengths - every 12 seconds.

Between the AIA and two other instruments on board, SDO sends down a whopping 1.5 terabytes of data a day. AIA is responsible for about half of that.

Every day it provides 57,600 detailed images of the sun that show the dance of how solar material sways and sometimes erupts in the solar atmosphere, the corona.

Since its launch Feb 11, 2010, SDO has provided stunning images of the Sun to help scientists better understand how the roiling corona gets to temperatures some 1,000 times hotter than the Sun's surface, what causes giant eruptions such as solar flares, and why the Sun's magnetic fields are constantly on the move.

Check out this article from TOI!

PUNE, 19th Jan: A 13-day expedition to Antarctica has changed 19-year-old Pune student Zareen Cheema's outlook towards life. It has not only taught her to fight against odds but also resolve to study climate change. 

Cheema, a student of mechanical engineering at Cummins College in the city, was the only Indian student among the group of 66 high school and university students selected from 70 universities across the world, for the 'Students on Ice 2014' expedition. 

After the selection last June, the students had to decide their topics of research. Cheema chose to learn about LIDAR, a remote sensing technology that measures distance by illuminating a target with laser and analyzing the reflected light. Training started from October and comprised practical examples and readings collected from various islands and ice tops. 

The trip was not without hiccups. The first obstacle was raising the money required to complete this trip, where she planned to visit British explorer Ernest Shackleton's rescue points and see the brilliant light phenomena of the aurora australis first-hand. 

"I told my father that he should worry only about the transport till Toronto and I would manage the rest. I was determined and waited patiently till I raised a considerable amount through a crowd-sourcing website," she said. 

Full of first-hand stories from the southernmost part of the world, Cheema sees life from a different perspective now. "It was a learning of many sorts as we struggled on our own on that difficult terrain, where every step forward in ice is an effort. It was scary when my boot got stuck in the snow and my glove came off in the sub-zero conditions when we had to walk for an hour. It was a lesson in determination." 

Students on Ice's goal is to educate and inspire the youth, through discovery and learning in the polar regions and help them understand our changing environment, said Geoff Green, explorer and founder of the programme. 

While the students occasionally caught sight of the penguins, wandering albatrosses, seals and the fin whale, Cheema said the sight of icebergs melting and carving out of ice shelves strengthened her resolve to study climate. 

"We also learned about the history of Antarctica, the biodiversity and the Antarctica treaty from oceanologists, marine biologists and explorers," she said. 

Cheema is also the youngest among the 660 people from across the world hoping to land a spot on the one-way manned mission to Mars. She is gearing up for another MarsOne interview next week, and hopes to make it to the final list that will be announced by February-end. "Zareen has a passion for learning and visiting Antarctica was a great way to fuel her dream to go to Mars. She was a wonderful ambassador of India," said Green.

Best Regards,

Archana.
