The data were collected from December 2006 to July 2007 in the coral reefs around the islands Bunaken and Gangga and near the city Manado. Secchi depth was estimated by lowering a Secchi disc from a boat. Salinity was measured with a Refractometer. Tidal cycle information was taken from a tide calendar. Wind speed was estimated based on wave development. Underwater visibility was estimated by divers and water temperature was measured with a dive computer (Suunto Favor).124.73659125.058161.541251.76924Fukui Point, Bunaken Island, North SulawesiRaymond's Point, Bunaken Island, North SulawesiLihage Island near Gangga Island, North SulawesiLakehe Beach, Gangga Island, North SulawesiSouth of Gangga Island, North SulawesiReef close to village Meras near Manado, North Sulawesi
