Investigator Shoal, also known as Malay: Terumbu Peninjau; Pawikan Shoal (Tagalog: Buhanginan ng Pawikan, lit. 'Sandbank of Sea Turtle'); Vietnamese: bãi Thám Hiểm; chữ Nôm: 𣺽探險; Mandarin Chinese: 榆亞暗沙/榆亚暗沙; pinyin: Yúyà ànshā, is located in the SW of Dangerous Ground in the Spratly Islands of the South China Sea.[1]
It is an atoll above water at low tide; some large rocks at the western end might be visible at high water. The atoll is 32.1 kilometres (19.9 mi) and is up to 10.6 km wide.[2] The total atoll area is 188 square kilometres (73 sq mi). The lagoon is up to 45 meters deep.[3]
It is one of the areas in the Spratly Islands occupied by Malaysia. The Royal Malaysian Navy has maintained an "offshore naval station" there called "Station Papa" since 1999.[4]
