Surf karren form along marine limestone and dolomite coasts where the surf sprays water onto abrasion surfaces that lie slightly above normal sea level. They are a result of corrosion caused by the mixing of sea- and rainwater, but do not exist under the sea surface as seawater is not limestone-corrosive. Beyond the splashwater zone the karren are much less sharp .
