Scientists pioneer technique to identify marine life hotspots in Scotland

Marine specialists have been using satellite images to help identify important areas for marine life around Scotland's coasts, according to a report published by Scottish Natural Heritage (SNH) today (Tuesday 1^st April).

Recently available satellite images of ocean colour have been used to help marine biologists identify areas known as fronts. It is the first time the technique has been used successfully in this way.

Fronts form where different water bodies meet, such as between coastal and saltier oceanic waters. Marine scientists believe these areas attract and support a wider range of marine wildlife and in higher numbers. Mixing of different types of water at fronts can provide nutrients for phytoplankton, the small plants at the base of the marine food web, to grow. This can attract fish and predators such as seabirds and marine mammals to the area.

Morven Carruthers at SNH said: "The high resolution of the satellite images we’ve used helps us to identify fronts close to Scotland's coast. Areas of importance for marine life, such as fronts, are being used to help identify Marine Protected Areas in Scotland's seas."
