Abstract

While a series of biological, environmental and ecological studies regarding ocean acidification is taking place at a shallow CO2 seep occurring in an offshore location of Shikine Island, Tokyo, Japan, we studied the human dimensions of the seep’s existence. In order to assess the resident’s recognition, we interviewed regular users of the area whose livelihoods were likely affected by the seep, i.e., fishermem and diving operators. While we found negative recognition by more than half of fishermen, a diving operator exhibited positive recognition. We further assessed visual components which contributed to the positive acceptance by analyzing photographic records. We found that bubble vents and sea turtles were the components unique to the seep area, and were used as tourism resources.
