This is a video from National Geographic featuring fisherman and scientists who work in Long Island’s Great South Bay that separates Fire Island from the south shore of the main island. Last year during Hurricane Sandy, Fire Island, a long narrow barrier island, was split in two and a new inlet was formed. Now, ocean water flowing into the bay is filtering out the polluted water and bringing declining shelfish populations back to life. The new inlet/breach in the island has been a controversial issue – local residents see the cleaner water as a positive change and a potential turning point to bring jobs back to the bay. Others think the inlet is unnatural and will eventually correct itself if not manually filled in via dredging first.
