Survey and Monitoring -
Satellite images
Satellite imagery is relatively new tool for survey and monitoring work, providing an aerial view of an area. Satellites can be fitted with multi-spectral sensing equipement to show aspects not normally visiable to the human senses.
Satellites can record accurate sea surface temperatures, which can be used for studying climate change. Radar systems fitted to satellites can observe the sea state recording surface waves, fronts, internal waves, currents and wind. Measurements from radar systems are very sensitive to sea surface roughness, allowing the detection of oil spills. Long term data dervived from satellites can be used to produce predictive models.
Data derived from satellites has proven very useful for investigating climatic and oceanic patterns and systems. The British National Space Centre (BNSC) is focused on developing a long term strategy for the monitoring of UK waters.
At present, whilst they can provide useful regional data their resolution is not sufficient for the type of data required at a local level.
