IPY

This Ice Stories Web site was created in celebration of the International Polar Year (IPY) 2007–08, but what exactly is that? The IPY is a large international scientific initiative with a history that spans more than a century.

The inspiration for the first IPY, held in 1882–83, came from Austrian scientist, explorer, and naval officer Karl Weyprecht. He realized that studying the poles was an important way to understand meteorology and geophysics, but he also knew that it was a big undertaking; it couldn’t be done by one nation alone. Inspired by this idea, a group called the International Polar Commission was established in 1879; it organized the first IPY.

Twelve countries, including the United States, participated; they collectively completed fifteen polar expeditions: two to Antarctica, and thirteen to the Arctic. They probably spent more time trying to survive than they did doing science. There were also problems with countries publishing their own data rather than doing it cooperatively with other nations. But this first IPY was still very valuable. It set in motion the important idea of a collaborative, international scientific effort to study the poles, a spark that rekindled fifty years later.

The second IPY (1932–1933) was more scientifically successful than the first. It was proposed and promoted by the International Meteorological Organization as a way to study the newly discovered jet stream (a current of rapidly moving upper atmosphere winds) and its global effects. New inventions—airplanes and motorized sea and land vehicles—made life easier for the scientists. This time, the number of participating nations jumped to forty. Despite challenging economic issues (this IPY took place during the middle of the Great Depression), it brought advances in our understanding of magnetism, atmospheric science, and radio science and technology. Forty permanent observation stations were built in the Artic, and the second U.S.-backed Byrd expedition built the first inland research station in Antarctica.

The second IPY was followed, in 1957–58, by the International Geophysical Year (IGY), a major scientific event that propelled our scientific understanding, particularly of geophysics, far forward. It was proposed by prominent post–World War II physicists, who wanted to use some of the latest technology developed for the war—radar, computers, and rockets—for scientific research, particularly in the upper atmosphere. Sixty-seven countries and more than 4,000 research stations participated.

There were many breakthroughs. Important research into continental drift (when the continents change position in relation to each other) was done at this time. The Gambutserv Mountains, a huge completely ice-covered mountain range in East Antarctica, were discovered. Scientists were able to develop the first informed estimates of Antarctica’s ice mass by traversing the continent. The space age was born when the world’s first satellites (the Soviet Union’s Sputnik I in 1957 and the United States’ Explorer I in 1958) were launched. And the Van Allen radiation belts, which encircle the earth trapping cosmic radiation, were discovered. Twenty years later, in 1970, the scientific disciplines emphasized during IGY became the foundation of many of the United States’ National Oceanic and Atmospheric Administration (NOAA) programs and activities.


The twelve nations that were active during the 1957–58 IGY signed the Antarctic Treaty; their flags fly around the ceremonial pole at the Amundsen-Scott South Pole station.

There was also a political outcome to the collaborative work of the IGY. The Antarctic Treaty, written in 1959 and ratified in 1961, states, among other things, that information has to be shared openly among researchers; that science done in Antarctic is for peaceful, noncommercial uses; and that no weapons development or testing can take place there. The Treaty also forbids mineral extraction of any kind and protects the terrestrial ecosystem of Antarctica, which makes it a much different place than the Arctic.

The current IPY is, technically, not a year, it’s two (March 2007–March 2009); the two years allow for two full field seasons at both poles. Like its predecessors, this IPY is also a major international, interdisciplinary scientific effort targeted at better understanding the polar regions. Thousands of scientists from over sixty countries, working on over two hundred research projects, are using state-of-the-art tools and techniques to conduct biological, physical, and social research. The goal of this IPY is to explore new frontiers in polar science, improve our understanding of the pivotal role of the polar regions in global processes, and educate the public about the Arctic and Antarctica (that’s where this Web site fits in). Its organizers also hope that this IPY will attract the next generation of scientists and engineers to the poles. The entire worldwide effort is overseen by the International Council for Science (ICSU), and the World Meteorological Organization (WMO).

It’s hard to know what breakthroughs will come from recent data collected, but this IPY has already taken a different kind of leap forward. During the 1957–58 IGY, the majority of countries, including the United States, didn’t allow women to work on The Ice. Now, women account for almost half of all IPY scientists, and many are project leaders. (To learn more about women and the Ice, click here.)

Fishing in Antarctic Waters? http://icestories.exploratorium.edu/dispatches/fishing-in-antarctic-waters/ http://icestories.exploratorium.edu/dispatches/fishing-in-antarctic-waters/#comments Mon, 03 Nov 2008 19:07:40 +0000 Cassandra Brooks http://icestories.exploratorium.edu/dispatches/?p=910 MOSS LANDING, CALIFORNIA– In early July, 2008, I traveled to Saint Petersburg, Russia, to join thousands of other polar scientists for the SCAR (Scientific Committee on Antarctic Research) Open Science Conference. SCAR is an inter-disciplinary committee responsible for initiating, developing and coordinating international scientific research in the Antarctic region and understanding its effect on the greater Earth system. This is the last in a series of dispatches in which I share the latest polar science I learned from SCAR.

The morning of July 11th was the culmination of the conference: I finally presented my Antarctic toothfish work. Presenting at a conference is not about being the star of the show; it’s about our responsibility as scientists to communicate our work to our colleagues, the public, and in my case, to resource managers.


Presenting my Antarctic toothfish work at SCAR.

I came upon Antarctic toothfish four years ago when I started graduate school. I had been interested in fisheries management for years and was looking for a way I could contribute to this global problem. Antarctic toothfish erupted onto the fishery scene in the last ten years because of declines in its cousin fish, Patagonian toothfish. Both species are more commonly known on the market as the popular and expensive Chilean Sea Bass.

Prior to my work, I didn’t know much about Antarctic fisheries. Like most people, I couldn’t imagine why fishermen would travel so far for fish. But world fishery trends hold the answer. Recent Food and Agricultural Organization statistics state that 97 percent of our world fisheries are fully exploited, overfished or collapsed, leaving a mere 3 percent unexplored, pushing fishermen into remote places like Antarctica.

You can imagine how hard it is to manage fisheries in a place like Antarctica, but in 1982 an international group came together to do just this. They formed the Convention for the Conservation of Antarctic Marine Living Resources and have been managing Antarctic wildlife every since. My study met a request by CCAMLR for more life history information about Antarctic toothfish, with the hopes of sustainable management for the growing fishery.

I stood before my colleagues at SCAR and presented what I had learned about Antarctic toothfish, including how they grow slowly and live a long time — close to 40 years. Many fish that share these characteristics have been overharvested quickly because they can’t grow and reproduce fast enough to keep up with demands of the fishery. I discussed past trends and future concerns.

To my delight, some of the folks from CCAMLR were there in the audience. After the talk, we continued to discuss toothfish management. Is it even possible to have a sustainable toothfish fishery? And if so, what would it take? The first step is to apply the research to management. With their help, this toothfish work is now being presented at the yearly CCAMLR management meeting in Hobart, Australia, and all my years of toiling will not go to waste.

The conference ended on a high note. I had an amazing experience partaking in this international collaboration of scientists, all of us working together to find solutions to global problems and dedicated to learning more about our poles. Thanks for joining me and keep up with Ice Stories as we collectively share our work with you in the second half of International Polar Year.
