Low tide and coastal erosion





Climate change is affecting sea level all over the world. One 'extra' lesson we learned at the TAMAR sea turtle conservation project in Salvador, needed no special posters or displays as it was wide open and visible to all visitors... the aggressive sea level rise at Tamar's seafront base! We had already witnessed and photographically documented this phenomenon in last year's edition of Sciences Brazil (2010), along Salvador's gorgeous beaches. Here at Tamar, while observing the exposure of the rocky shore at low tide, we also almost witnessed a couple of visitors almost fall in one of the rather large pits formed by high tide water making its way inland under the Tamar sea wall base. Looking out more carefully we also can see the sandbags and woodpiles are being installed so as to protect the present shoreline from more erosion. Apparently, this will not be enough...!
