Sea level rise will be responsible for one of the most profound and costly impacts of climate change on human society, so gathering accurate data on sea levels worldwide is vitally important. Although sea level is monitored at hundreds of sites through the Intergovernmental Oceanographic Commission and World Meteorological Organization's Global Sea Level Observing System, there are large gaps in data from the Arctic and Antarctic because measuring sea level along polar coastlines is a huge technical challenge. By enhancing existing sea level gauges in the Antarctic, and installing new, high-tech devices in the Arctic that will provide high-frequency, real time data, this project will provide the missing piece of the jigsaw for scientists monitoring sea level rise across the globe. The same sea level data can also be used to monitor changes in the circulation of the high-latitude oceans, which in turn may provide clues as to why sea level is rising.

This project is designed to bring together a wide range of scholars, students, institutions, and approaches to study the key-concepts of movement, communication and strategies among arctic peoples.

Involving a team of scientists from 11 countries, this project will measure the temperature, saltiness and flow speed of the water from continental shelf and slope, including under ice environments. This is something scientists know very little about, but the data are crucial for developing better global climate models. The few recent measurements we have suggest that the water close to Antarctica is getting fresher (less salty). But where is this extra fresh water coming from? Only by measuring – especially during winter – the properties of the water and how fast it is flowing will we be able to understand the processes that are going on, and make sure that these are put into our climate models correctly. There has never been a concerted effort to make measurements on the Antarctic continental shelf and slope during the winter. IPY is enabling everyone to work together to make this happen, by leaving instruments on the sea bed and in the water for a year, even when the ice is covering the sea surface above them. Each nation is going to deploy instruments so that a circumpolar coverage can be obtained for the first time. As well gathering data during IPY, some of SASSI's instruments will be left in place after IPY, providing an important legacy for future research.

The SCAR-programme EBA (2004-13) will address the impacts of climate change on species biodiversity, evolutionary adaptations and depletion of marine fisheries on community dynamics in the Southern Ocean. A better understanding of the effect of such changes will be obtained by investigating the acclimatory responses to high latitudes. It will contribute to development of a baseline understanding of sensitive ecosystems.

Polar Heritage - once lost, it can never be regained. Protection and preservation of early scientific bases in polar regions. A multidisciplinary and international conference with presentations focussed on technical and administrative issues associated with the protection and preservation of historic scientific bases and in "Historic polar resources are disappearing! Once lost, it can never be regained. Protection and preservation of early scientific bases in polar regions. The age of discovery in polar regions also brought scientific research and soon the first non-indigenous structures were built. Regretably some of these historic sites have already been lost and more are under threat. The International Polar Heritage Committee IPY conference in Barrow Alaska, the site of one the first IPY scientific stations will assemble organisations and individuals working to protect these sites so they can share their expertise and experience to preserve them.

Northern High Latitude Climate variability during the past 2000 years:implications for human settlement. "NORCLIM investigates how natural climate change over the past two millenia has affected human presence in the Arctic. Examples are the timing of Viking settlement on the Faroer, Iceland, Greenland and Newfoundland and the shift in whaling activities from Spitsbergen to Davis Strait during the Little Ice Age. To achieve the NORCLIM goals, geologists, climatologists and archeologists from seven counties will carry out marine and terrestrial fieldwork on key locations along a Newfoundland-Spitsbergen transect.

Ice cores tell us how climate and atmospheric composition have varied in the past. IPICS will develop international plans for new projects on timescales from 2000 to over a million years. A focus in IPY will be on starting a core to bedrock in Greenland that aims to show us how the climate and ice sheet responded during the last warm interglacial period on Earth.

Investigative Scientific Antarctic Voyages for Youth RSV-INTREPID plans to conduct two independent 40 day investigative science expeditions to Antarctica involving up to 120 students mentored by 80 young post-graduate scientists. The multi-disciplinary scientific program, tasked by a consortium of scientific agencies and universities, is consonant with the six IPY research themes and will consist of a variety of challenging ship-board and shore-based projects.

"The APICS project is an effort to understand all aspects of the ice and climate system in one of the most rapidly-changing regions on Earth - the Antarctic Peninsula' Larsen B embayment. In 2002, a huge section of this ice shelf collapsed, after decades of record-warm summers. Following this collapse, glaciers in the region accelerated abruptly. Coastal ecology and nearby ocean currents changed drastically due to the loss, and a preliminary survey of the newly-exposed ocean floor showed previously unknown sub-ice life forms still present after the break-up. The APICS project is intended to use the dynamic Larsen B ice shelf region as a natural laboratory for what to expect from climate warming in Antarctica. It is a collaborative effort among 11 major U.S. research institutions, and four other countries (Spain, Belgium, Argentina, and England) to coordinate research across several disciplines, using the US research vessel Nathaniel B. Palmer as a platform. The work will include an ice core at the crest of the ice ridge above the Larsen B, remote robotic systems for glacier measurements, extensive flights to visit unique rock outcrops that may reveal the history of the region, and a remotely piloted vehicle for exploring the new life forms and ocean sediment changes. The first field season is currently planned for February/March of 2008."
