什么是离岸流 用英语回答

离岸流指的是一种沿着海岸线从陆地指向海洋的水流。这种海洋流通常发生在海浪和潮汐作用下，它可以带走沿岸的水和沉积物，对海岸线地形和生态系统具有影响。

Offshore currents, also known as coastal currents, refer to the water flow along the coastline from land towards the ocean. These ocean currents are typically driven by waves and tides, and they can transport water and sediments along the coast, influencing coastal topography and ecosystems.
