The Shiretoko Peninsula which is located between Sea of Okhotsk and Nemuro Channel enable us to observe a connection with the ocean and inland easily, the having many kinds variety of the creature was recognized, and it was registered with natural world heritage. In Shiretoko, the nutrient of the ocean is found to be transported to inland by birds, salmon and trout. It is expected that drift ice brings nutrient from the northern part of Okhotsk Sea to Shiretoko during winter, which results in the sound ecological system and the great biodiversity in Shiretoko Peninsula. However, it is not clarified how much nutrient is brought by drift ice to Shiretoko exactly. In this study, we thus aim to estimate how much nutrient is transported from inland and drift ice to the ocean and how much is brought back to inland from the ocean by using isotope analysis.
