The BAS base at Rothera on the Antarctic Peninsula. The other main BAS base is located on the Brunt Ice Shelf.

ARIES data is used for met forecasting to support flights for field scientists and aerial photography.

Clouds and weather Clouds and weather systemssystems

Cloud data assessed to help in planning of new bas to replace Halley on the Brunt Ice Shelf.

Ice shelf monitoringIce shelf monitoring

AVHRR data used in conjunction with SAR and altimetry data to monitor ice shelves on the Antarctic Peninsula.

More detail of the break-up of the Larsen Ice Shelf available from data such as the Landsat 7 ETM+ image.

Volcanic monitoringVolcanic monitoring

Monitoring of volcanic eruptions on the South Sandwich Islands.

For a given lava surface temperature it is possible to estimate the lava surface area and derive an indication of volcanic activity over the duration of the ARIES archive.

Similar volcanic detection algorithms are now integrated into the MODIS processing chain.

This example comes from the MODVOLC system run by the University of Hawaii.

Biology of the Southern Biology of the Southern OceanOcean

Some SeaWiFS data has been collected by the ARIES system.

SeaWiFS and MODIS ocean colour products are used in the study of the biology of the Southern Ocean.

Using statistical techniques to determine spatial and temporal variability of chlorophyll concentration.

Satellite data is also compared with in-situ data acquired during scientific cruises.
