Expeditions to the Polar Regions

netbros — Mon, 09 Nov 2009 10:01:49 -0800

The Polar Discovery team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and covered five scientific expeditions. The science projects explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through photo essays and other multimedia, they explain how scientists collected data and what they discovered about the rapidly changing polar regions. From the awesome folks at WHOI.

The NRW timeline

NRW 1946—2006. Short articles chronicling North Rhine-Westphalia. The site has one rather large shortcoming though, the video clips cannot be accessed (only available on VHS within the State!).

There Could Be Blood

Andy Grove on Our Electric Future - "Energy independence [viz.] is the wrong goal. Here is a plan Americans can stick to." Perhaps some infrastructure spending^1,2 is in order? [etc., &c., cf.] also see :P - "Tesla Motors Is Delivering Cars" - "Superconducting Power Grid Launches In New York" - "New heights reached in polymer based solar cell efficiency"

[S]pray a sheet of glass with a mixture of dyes combined with a substance called tris(8-hydroxyquinoline) aluminium. In combination, the dyes and the glass act as the waveguide, preventing light from escaping. Meanwhile, the interaction between the different dye molecules and those of the tris(8-hydroxyquinoline) aluminium allows a quantum-mechanical phenomenon, called Förster energy transfer, to come into play. This eliminates the reabsorption loss by ensuring that light is re-emitted at a frequency which the dye molecules cannot then reabsorb. On top of this—literally—Dr Currie and Dr Mapel have come up with another trick: placing a second sandwich of dye and glass over the first. The upper layer of dye intercepts high-energy light, such as ultraviolet. The lower one captures longer wavelengths that have passed unperturbed through the upper, and also any lower-energy light that has been re-emitted within the top layer and somehow escaped. The upshot is a device that, even as a prototype, converts ten times more of the incident light into electricity than a conventional solar cell. [and btw]

cheers!

The ocean gives us life. It gives us oxygen, the rain, food, excitement, wonder, and mystery. The ocean buffers the weather and helps regulate global temperature. It manages vast amounts of our pollutants, contains all kinds of amazing creatures, and supports all life on our planet. But, the ocean is just now beginning to be understood and with that understanding comes the increasing realization that the ocean is in trouble. Marine conservation efforts are outnumbered by the problems. MarineBio is here to call attention to those issues and to provide information to inspire the actions necessary to address them.

Smoke and mirrors

Meet Joules the climate change-sceptic robot. Joules is employed to teach 8-14 year-old school children in the UK about energy use. Joules says: "oil and gas could be in short supply in about 50 years time. The earth is believed to be getting warmer and sea levels apper to be rising. Energy Chest is funded in part by the world's biggest oil company: ExxonMobil. Energy Chest follows a report by the Union of Concerned Scientists, entitled “Smoke, Mirrors & Hot Air” [PDF] which demonstrated how the "oil giant has adopted the tobacco industry’s disinformation tactics", (as well as some of their personnel), to "cloud the scientific understanding of climate change and delay action on the issue". While in the UK, the Royal Society has complained about ExxonMobil campaign to fund groups that attempt to undermine the scientific consensus on climate change. Not that the kids are being told all that when they stumble across Joules or - worse - are being shown him by their teacher.

Where do we go from here? Why is the path unclear?

The antidote to LOLbushsuxx0rs. Over the course of the past week, Slate ran a ten (10!)-piece series, "Fixin' It", in which various writers postulated how the course of various aspects of the United States' military, culture, and policies could be redirected for the better. Although the articles are not entirely devoid of Bush criticism, there's mostly a fairly rare focus on the positive actions to be taken from here onward by the next President (whether it be McCain or Obama or Clinton).

Science and Technology in the 2008 Presidential Election

Dr. President: "The next president of the United States of America will control a $150 billion annual research budget, 200,000 scientists, and 38 major research institutions and all their related labs. This president will shape human endeavors in space, bioethics debates, and the energy landscape of the 21st century." With the coming election, the AAAS has created a new website and devoted a section of their journal Science to the Democratic and Republican candidates' positions on science and technology issues. But to help further clarify their positions, some people are calling for the candidates to have a presidential debate on science and technology. [Via The Intersection and Wired Science.]

A different kind of eco-challenge

mtvU and GE are sponsoring a contest among colleges to create sustainable energy projects. The finalists' projects range from campus-wide runoff reduction proposals to a public bicycle-based laptop charger for students. The winner receives a $25,000 grant to implement their project, which is unfortunately small potatoes compared to the millions of dollars required to, for example, convert an entire vehicle fleet to biodiesel. unrelated, previously.
