Understanding ecosystems

Understanding ecosystems

Date: 2003
Creator: British Antactic Survey
Description: Plants and animals live in environments which change over different periods of time. Some changes happen each year with the seasons, whilst others take hundreds or even millions of years. As these changes occur, living organisms respond in different ways. To cope with the changing seasons, individuals can change their physiology or behaviour, for instance by hibernating or migration. In response to longer-scale change, species may adapt through evolutionary change. If they cannot, they must either move away or become extinct.

Climate change

Climate change

Date: 2003
Creator: British Antactic Survey
Description: The Earth's climate has not been constant over geological time. This record is contained in ice, which has built up as snowfall accumulated in distinct yearly layers. Pockets of air trapped between the snow crystals contain traces of past atmospheres, which in turn tell us about the climate at the time the snow formed. Glaciologists collect this record by drilling ice cores and then use sensitive chemical techniques to analyse the layers.

Antarctic fact-file

Antarctic fact-file

Date: 2003
Creator: British Antactic Survey
Description: Antarctica is a continent for science. All countries working in Antarctica carry out scientific research, in a surprising range of physical and biological sciences, from the vastness of space to the minute scale of micro-organisms. Activities are regulated by the Antarctic Treaty, which has been in force since 1959 and is signed by all countries operating there. The Treaty reserves the continent for peaceful purposes, and all military and industrial activities are banned.

The ozone hole

The ozone hole

Date: 2003
Creator: British Antactic Survey
Description: Discovery of the hole in the ozone layer showed that human activity can have major, and often unexpected impacts on the planet. The destruction of ozone in the stratosphere high above the planet's surface has been brought about as the result of the widespread use of chemicals which under normal conditions are chemically inert and harmless
