CONCLUSIONS— TOWARD IPY 2007– 2008<br />

As we enter <strong>the</strong> Intern<strong>at</strong>ional <strong>Polar</strong> Year of 2007–<br />

2008, <strong>to</strong>day’s scientists are heirs <strong>to</strong> a grand research tradition.<br />

With more than 60 n<strong>at</strong>ions particip<strong>at</strong>ing, <strong>the</strong> current<br />

IPY has a broad interdisciplinary focus on environmental<br />

change. Six scientifi c <strong>the</strong>mes provide a framework for IPY<br />

2007– 2008 (Allison et al., 2007:13):<br />

1. St<strong>at</strong>us: <strong>to</strong> determine <strong>the</strong> present environmental st<strong>at</strong>us<br />

of <strong>the</strong> polar regions;<br />

2. Change: <strong>to</strong> quantify and understand past and present<br />

n<strong>at</strong>ural environmental and social change in <strong>the</strong> polar<br />

regions and <strong>to</strong> improve projections of future change;<br />

3. Global linkages: <strong>to</strong> advance understanding on all scales<br />

of <strong>the</strong> links and interactions between polar regions and<br />

<strong>the</strong> rest of <strong>the</strong> globe, and of <strong>the</strong> processes controlling<br />

<strong>the</strong>se;<br />

4. New frontiers: <strong>to</strong> investig<strong>at</strong>e <strong>the</strong> frontiers of science in<br />

<strong>the</strong> polar regions;<br />

5. Vantage point: <strong>to</strong> use <strong>the</strong> unique vantage point of <strong>the</strong><br />

polar regions <strong>to</strong> develop and enhance observ<strong>at</strong>ories<br />

from <strong>the</strong> interior of <strong>the</strong> earth <strong>to</strong> <strong>the</strong> sun and <strong>the</strong> cosmos<br />

beyond; and<br />

6. The human dimension: <strong>to</strong> investig<strong>at</strong>e <strong>the</strong> cultural, his<strong>to</strong>rical,<br />

and social processes th<strong>at</strong> shape <strong>the</strong> sustainability<br />

of circumpolar human societies and <strong>to</strong> identify <strong>the</strong>ir<br />

unique contributions <strong>to</strong> global cultural diversity and<br />

citizenship.<br />

The current IPY is supported by <strong>the</strong> l<strong>at</strong>est technologies<br />

including computer models of ice sheet dynamics, ice<br />

cores reaching all <strong>the</strong> way <strong>to</strong> bedrock, and advanced surface,<br />

airborne, and s<strong>at</strong>ellite sensors th<strong>at</strong> measure ice thickness,<br />

surface elev<strong>at</strong>ion, mass balance, and subsurface conditions.<br />
