Oil from an Iranian tanker that sank in the East China Sea has diffused into four separate slicks, covering a combined area of just over 100 square km (39 square miles), Chinese authorities said on Thursday.
Earlier satellite imaging showed two large slicks, with the larger one also thicker and more concentrated, but the latest data had found four slicks ranging in size from 48 square kilometers (19 square miles) to 5.5 square kilometers (2.1 square miles), the State Oceanic Administration (SOA) said.
The large tanker Sanchi sank in the worst oil ship disaster in decades on Sunday, raising worries about damage to the marine ecosystem. The bodies of two sailors were recovered from the ship while a third body was pulled from the sea near the vessel. The remaining 29 crew of the ship are presumed dead.
