Summary

• Responsibility for co-ordination of remote
  sensing data and activities in BAS
• BAS science programme makes use of a wide range
  of remote sensing applications
• Ensure that we keep track of new developments and
  forthcoming changes to existing systems that will
  impact our operations and science programme
• This presentation will provide an overview of
  some applications of satellite data

3
Satellite imagery used for mapping, cartography
glaciology, geology
4
field work planning and operations support. But
this presentation will concentrate on the use of
the AVHRR data collected by our SRIES system and
analogous datasets.

Application areas

• Real time applications in weather forecasting at
  Rothera Station
• Field operations support
• Logistics and new base planning
• Research at BAS into
• Synoptic and mesoscale weather systems
• Antarctic clouds
• Ice shelf monitoring
• Biological science applications
• Volcanoes

6
The BAS base at Rothera on the Antarctic
Peninsula. The other main BAS base is located on
the Brunt Ice Shelf.

Ice shelf monitoring
18
AVHRR data used in conjunction with SAR and
altimetry data to monitor ice shelves on the
Antarctic Peninsula.
19
More detail of the break-up of the Larsen Ice
Shelf available from data such as the Landsat 7
ETM image.
20
Volcanic monitoring
21
Monitoring of volcanic eruptions on the South
Sandwich Islands.
22
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.
23
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.
24
Biology of the Southern Ocean
25
Some SeaWiFS data has been collected by the ARIES
system.
26
SeaWiFS and MODIS ocean colour products are used
in the study of the biology of the Southern Ocean.
27
Using statistical techniques to determine spatial
and temporal variability of chlorophyll
concentration.
28
Satellite data is also compared with in-situ data
acquired during scientific cruises.
