Plastic on Our Coasts

In preparation for a future project (more about that at a later date), crews have been issued with powerful new cameras and have been trialling them by taking pictures of short sections of Scottish coastline from around 800 feet.  The purpose is to capture various pollutants (mainly plastic) by accurate imagery.  The photographs are taken in large file format and analyzed after the flight to reveal the extent of any pollution and its exact location.  Images are taken if plastic is spotted from the air by observers but also of areas where accumulations of washed-up plastic are typical.  With experience, crews quickly get a feel for these areas and analysis of the subsequent images often reveals significant pollution even when not immediately apparent from the air.  The advantage of large file sized digital images is that they can be expanded considerably to reveal extra detail.
