10 miles from shore (L4)
L4 is an ocean monitoring station located
10 miles from Plymouth and represents deep coastal conditions near Plymouth.
A scientific buoy is operated at the station by
Plymouth Marine Laboratory which is equipped with an array of sensors to autonomously measure a suite of marine and atmospheric parameters every hour. This information then feeds into the models on which MyCoast is based. See the
Western Channel Observatory website for further details.
