Mariveles Reef
Mariveles Reef, known as Nanhai Jiao in China, Terumbu Mantanani in Malaysia, đá Kỳ Vân in Vietnam and Mariveles in the Philippines, is located in the SW of Dangerous Ground in the Spratly Islands. It is slightly east of north from Swallow Reef and southeast of Barque Canada Reef.
It dries at high tide enclosing two large lagoons in a figure of eight formation with a sand cay between them. This small cay, 1.5–2 m high, and some isolated rocks are just visible at high water.
The Royal Malaysian Navy has maintained an "offshore naval station" there called "Station Mike" since 1986.
