Coast erosion

Tacumshin barrier. This short, time-lapse sequence, created by Jimmy Goodwin, evidences the rapid rate of erosion of part of the barrier at Tacumshin Lake. It features a series of five aerial images of part of Grogan Burrow dating from 1995 to present. While the loop plays continually, it is best to start in 1995 with the only black-and-white image. The Tunnel draining the lagoon is located bottom centre of the image. Note bottom left how the shoreline recedes to consume the former horse gallop running parallel with the coast. Note also, the recently-formed washover fans, especially immediately east (right) of The Tunnel. The original images are at http://map.geohive.ie.
