Scientists just enjoy a hole over 3,500 icefires to get to Loch Antarctic worried

While you've had baking biscuits and a & # 39; Demonstrating Netflix messages over Christmas, a team of around 50 scientists, drillters and supporters tried to boost through almost 4,000 feet to get to an Antarctic lake for just the second time in human history. And people, they did it.

On Friday, the Antarctic Lakes Lakes Scientific (SALSA) team published that they had reached Lake Mercer after they had been able to go. melted through the river frozen separately with high brush drill, hot water. The multi-year effort is to include the subglacial lake of around 400 scientists found over Antarctica – a & # 39; offers rare opportunities to explore biology and chemistry of the most remote ecosystems on Earth.

The same lake is another suburban lake on streaming into nearby Lake Whillans, sampled in 2013 – has shown that these large environments can accommodate different microbial life. Naturally, scientists are wrong to see what they find to fall in the waters of Lake Mercer.

"We do not know what we find," said John Priscu, a biogeochemist at the State University of Montana and a leading scientist for SALSA, with Earther with a satellite phone from the SALSA drill camp on the Whillans Red Park. "We just learn, not just the second time this was done."

Priscu, along with two other SALSA scientists, three drillters and two marine technicians, went into the 650 mile camp from the McMurdo station on December 18. The remainder of the next day science team came with 8,000 pounds of cargo in some of the final supplies that the team had after millions of knots of advanced drill, advanced surgical equipment, and structures last December camp.

According to SALSA's latest blog, the team started to drilling his main dolphin on the afternoon of December 23. (High school dance doll that works like a well, his water went into the main hole after being broadcast and injured, previous night, tell Priscu to Earther) Things that seemed clear, with the crew arriving at the 54-square lake on the afternoon of December 26th after going on; drilling in depth of 3,556 feet (1,084 meters).

Now the loch is open, the sport has started. The SALSA team uses a series of instruments to explore the lake, and including a CTD probe (Maintenance, Heating, Heating) which estimates temperature and provides details of the structure of water and a distance run vehicle to remove a similar measure from the hole hole and video capture 4k. Researchers will sample specimens of data; water and microbial ridge, as well as ice from the top of the loch and bottom sediment.

Although much of the first analysis of these samples can be done on-site, the samples and the data collected through this effort may also keep busy scientists for years to come.

As well as finding unreadable life forms; seeing Sun in centuries, Lake Mercer is a subglacial; Provides a better understanding of local watering, including how lochan is like this; affecting the flow of large ice streams buried under. A survey of Loch Mercer sediments could help to determine whether it was like Loch Whillans closer to its; sea, once a marine environment, thus completing an important gap in our understanding of Antarctic history, Priscu said.

For Siegfried, who heads the geo-science team of four who has spent the last 5+ weeks in the service sector a long-range GPS range and electromagnetic instrument installation for mapping watercraft, the SALSA camp has been "amazing". The team came last week just like the drills were on the way. pulling their pipes out of the effluent after having to go; go to the lake, Siegfried Earther wrote via satellite internet. After spending a month out on the outside, there is a & # 39; Feeling it is in the city.

"We are deeply right [now] The sampling of the people who are always in a body of water has ever gotten under Antarctica, "wrote Siegfried."[S]o takes a while on the most interesting part & # 39; largest process [is]. "
