It is separated from offshore drift-ice by a region of open water, comprising a flaw lead/polynya. By August, much of the fast and drift-ice has melted and retreated from the southwestern Kara Sea, leaving behind

Here, we discuss how information obtained in such studies can be applied to studying the spreading of dissolved pollutants in the ocean. The discussion focuses on the transient tracers tritiumr 3 He and the H 18 OrH 16 O ratio of water. These tracers are used in combination with CFCs and 14 C in a 2 2 Ž. case study of Arctic Ocean contaminant transport to: 1 separate the freshwater components contained in the Ž .

At first glance the Arctic-based Fridtjof Nansen and Antarctic-based Sir Ernest Shackleton, and their most famous expeditions, are literally poles apart. But the expeditions wound up having much in common, including the fact that their fates were largely dependent on their drift trajectory in the sea ice pack

A powerful way to engage the public in appreciating current research is to link it with accounts of historical expeditions. We have been doing this at Barnard College, Columbia University, since 2003 through "Exploring the Poles,"

They teach at all levels, advise research students, make research discoveries and receive honors in recognition of their achievements. Despite these advances, women continue to be under-represented

Expeditions set off one after another to explore, map and make national claims. Fridtjof Nansen and Sir Ernest Shackleton were two of the most renowned polar explorers in their time, and their ...

To address this challenge, the National Council for Science and the Environment (NCSE) with NSF funding is creating a nationwide cyber-enabled learning community called CAMEL (Climate, Adaptation, and Mitigation e-Learning). CAMEL engages experts in science, policy and decision-making, education, and assessment in the production of a virtual toolbox of curricular resources designed for teaching climate change causes, consequences, and solutions. CAMEL is: ? Developing cyberinfrastructure that supports and promotes the creation of materials and community; ? Generating materials for the Encyclopedia of Earth, a site averaging 50,000 views per day; ? Ensuring that materials developed and shared are founded on the best available scientific information and follow the most appropriate educational practices; ? Assisting faculty at institutions of higher education across the United States as they create, improve, test, and share resources for teaching students not only how to diagnose climate change problems, but also to identify and effect solutions; ? Evaluating the determinants of successful community building using cybermedia. The community and resultant content range from general education to upper division courses for students in a variety of majors. At the center of the community are the 160 colleges and universities represented in NCSE's Council of Environmental Deans and Directors. Members of this group represent recognized expertise in virtually all areas of this project. A team with substantial experience with evaluating innovative initiatives in STEM education is administering the evaluation component.

U.S. universities as well as the federal government are responding to this bottleneck by increasing their investments in diversity initiatives. Following the 1999 Massachusetts Institute of Technology report about bias against female faculty, the U.S. National Science Foundation launched the ADVANCE program to increase the participation of women in science. The goal of the program is to use behavioral and social science research to understand and change individual and organizational behavior.

Industrial and other anthropogenic activities in the expansive Ob' and Yenisey watersheds also contribute organochlorines, heavy metals and oil to this region. Contaminant fate is influenced by the distribution of the river discharge and
