2011 Catlin Arctic Survey Prepares To Cross The Thin Blue Line
Over the past couple of years, the Catlin Arctic Survey team has been very active during the yearly Arctic Season. In 2009, a team of three explorers that included Pen Hadow, Ann Daniels, and Martin Hartley set out for the North Pole on foot, taking core samples of the ice as they went. Those samples would later be used to check the health of the Arctic pack-ice. In 2010, a new team, this time consisting of Daniels, Hartley, and Charlie Paton, made a similar trek, this time reach the Pole, while taking readings of the levels of CO2 in the ice, while a second team of scientists conducted a series of experiments at a stationary ice base. In 2011, the team is gearing up for another arctic adventure that has even more far reaching goals.
Earlier today the Catlin Arctic Survey announced a 10-week long expedition that will get underway in March. This time out, they will be examining the surface layers of the Arctic Ocean, and how changes in temperature there have had an effect on the climate in Europe and North America. In particular, they will be examining a "Thin Blue Line" of fresh water just beneath the surface of the Arctic sea ice that may offer some clues towards understanding the changes in ocean currents and their effects on global climate change.
Once again, the Survey team will establish an Ice Base, this time located aboard a ship off the coast of Ellef Ringnes Island, where scientists will conduct new and potentially ground breaking research into the potential for organic material in fresh water near the surface of the ocean for trapping heat from the sun, and causing the upper ocean layers to increase in temperature.
Meanwhile, two other teams will undertake separate missions of their own. Those teams will head out onto the ice, with one setting out to cross Prince Gustav Adolf Sea and the other will trek from the North Geographic Pole towards Greenland. Those explorers will collect samples from the water beneath the polar icecap that will be used to further the research project that is the brainchild of Dr. Simon Boxall of the National Oceanography Centre in Southampton, UK.
As I have over the past two years, I'll be following along with the progress of this important scientific expedition as it unfolds during the looming North Pole season which always gets underway in March. The Catlin Arctic Survey continues to grow in scope and sophistication each year, and true to form it has expanded once again. I love the fact that these adventurers are not only traveling through one of the most inhospitable environments on the planet, but they are doing so for research that may give us clues as to how and why our planet's climate and weather is changing. Expect regular updates starting in March.

NASA Discovers New Life Form
There has been a lot of speculation going on over the past couple of days regarding a press conference that is being held later today by NASA. When the invites went out to the press they simply said that the event was "to discuss an astrobiology finding." This of course got everyone excited and wondering if the space agency had, at long last, discovered life on another planet.
Turns out that isn't what happened, but they did discover new life on this planet. What's the big deal you ask? After all, aren't we finding new species all the time? Yep, that's true, but in this case, NASA has reportedly discovered a new bacteria that uses arsenic as the basic building blocks of its DNA. This is counter to every thing we know about life on this planet, and opens up the possibilities for life exiting in much harsher environments in the Universe.
According to this story from tech blog Gizmodo, the new bacteria was found in Mono Lake, California, and it's discovery completely changes the way we think about biology. Every living creature on our planet, until now, has been made up of carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. This finding shows that different elements can be used to create the building blocks of life, and that greatly opens up the chances of their being life on other planets as well.
We'll know a lot more this afternoon when the official announcement is made, but this is just another example of how amazing our planet really is. I've said it before, but I'll say it again. We really are just scratching the surface of what we know about this rock that we inhabit, let along the Universe as a whole. Just think about all the wonders that are still out there, waiting for us to discover them.

Noel Weeks onThe Hermeneutical Problem of Genesis 1-11
The following article is now available in PDF:
Noel Weeks, "The Hermeneutical Problem of Genesis 1-11," Themelios 4.1 (Sept. 1978): 11-19.
I remember how helpful this article was to me as a young Christian and am grateful to Dr Weeks for his kind permission to reproduce it here.
