flowing North Pacific Current to the north, the south flowing California Current to the east, and the west flowing North Equatorial Current to the south. The warm waters of the Kuroshio Current sustain the coral reefs of Japan, the northernmost coral reefs in the world. The part of the Kuroshio that branches into the Sea of Japan is called . Similar to the Atlantic Ocean's Gulf Stream, the Kuroshio Current creates warm ocean surface temperatures, and significant moisture in the atmosphere along the western Pacific basin, and thus produces and sustains tropical cyclones. Tropical cyclones, also known as typhoons, are formed when atmospheric instability, warm ocean surface temperatures, and moist air are combined to fuel an atmospheric low-pressure system. The Western North Pacific Ocean experiences an average of 25 typhoons annually. The majority of typhoons occur from July through October during northern hemisphere summer, and typically form where the Kuroshio Current is the warmest near the equator. Typhoons tend to track along the current's warm water poleward until they dissipate in colder waters. The strength (transport) of the Kuroshio varies along its path and seasonally. Within the Sea of Japan, observations suggest that the Kuroshio transport is relatively steady at about 25Sv (25 million cubic metres per second). The Kuroshio strengthens significantly when it rejoins the Pacific Ocean, reaching 65Sv (65 million cubic metres per second) southeast of Japan, although this transport has significant seasonal variability. The Kuroshio Current splits into Kuroshio Current extension and the Tsushima Current, as the currents wrap around Japanese Island and reconnects, changes in flow will impact the flows of the other currents. The path of the Kuroshio may have been different in the geologic past based on historical sea level and bathymetry, however there is currently conflicting scientific evidence. It has been proposed that lower sea-level and tectonics may have prevented the Kuroshio from entering the Sea of Japan during the last glacial period, approximately c. 115,000 – c. 11,700 years ago, and remained entirely within the Pacific basin. However, other proxies and ocean models have alternatively suggested that the Kuroshio path was relatively unaltered, possibly as far back as 700,000 years ago. Sediment transport The magnitude of the Kuroshio Current and seafloor bathymetry results in deep sea erosion and sediment transport in multiple regions. Offshore of Southern Taiwan on the Kenting Plateau erosion is likely caused by the strong bottom currents which increase
