Climate change has a profound effect on the knowledge and relationship that people have of and with their surroundings. Islanders have a particular relationship with the ocean, being completely surrounded by the water and often dependent on its resources. To denote this specific kind of knowledge, I use the term´Local Oceanic Knowledge´. Local Oceanic Knowledge involves kinaesthetic learning through physical and psychological activity connected to the sea. This research builds on three months of ethnographic fieldwork with fisherman, surfers, coastguards and environmentalists on the island of Siargao, the Philippines. The ethnographic film serves to explore the complex relationship with the ocean and the islanders by approaching knowledge in a way that embraces visual interaction. It is a manifestation of Local oceanic Knowledge as much as a depiction, showing that local oceanic knowledge in Siargao is being compromised by the effects of climate change.
