Mini subs to probe odd structures in BC lake

19.06.2008
Single person submersibles have been called in to help scientists retrieve samples from a lake in northern British Columbia that may hold vital clues to the history of life on Earth and on other planets.

Greg Slater, an environmental geochemist in the Faculty of Science, says the objects of scientific interest are unique carbonate rock structures, known as microbialites because they are covered with microbes. Some of these microbialites grow at depths up to 180 feet below the water's surface, too deep to reach by non-decompression SCUBA diving.

"Are they the result of biological or geological processes? Why are there different microbes living on them and how long have these microbial communities been preserved? These are some of our big questions," says Slater, who joined the international team researching these curious specimens three years ago.

Last fall, the project received welcome support from Nuytco Inc., manufacturer of single-person Deepworker submersibles, who offered two subs to enableresearchers to finally collect samples of the deepest microbialites. The dives will begin June 23.

"It's going to help us develop a baseline of understanding about life on our planet," says Slater. "As amazing as it sounds, the bottom of a lake can answer lots of questions about life on Earth. And how we explore this Lake will lay the groundwork for how we will explore Mars."

Astronaut Dave Williams, now a professor of surgery at McMaster University, will also participate in the research at Pavilion Lake. Trained as a Deepworker pilot, he is interested in the similarities between field scientific activities in the submersible and using a lunar rover for geological research in future missions sending astronauts back to the Moon.

"What's new about the work at Pavilion Lake this summer is the use of advanced underwater exploration technology to enable investigators to study previously inaccessible specimens," says Williams. "Now we're able to use Rover-type subs with robotic arms similar to what is envisioned for exploring the lunar surface."

Pavilion Lake is located about 500 kilometres north of Vancouver in Marble Canyon Provincial Park. It was formed by a glacier more than 10,000 years ago, and has for the last decade been the site of several studies into astrobiology.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
