Sea-drifts are the remnants of seaweed and other debris that wash up along the shoreline. Depending on the region, these can go by various names, such as wrack, beach-wrack, kelp, and algae. Other synonyms for sea-drifts include flotsam, jetsam, and pelagic drift. Flotsam refers to floating debris that has been cast away by the sea, while jetsam refers to goods that have been deliberately thrown overboard. Pelagic drift, on the other hand, refers to organic material that floats on the open ocean, and can only be seen from a ship or plane. Regardless of the name, sea-drifts are an essential part of the coastal ecosystem, providing nourishment and shelter for a variety of marine life.
