- Dangerous Ground is a large area in the southeast part of the South China Sea characterized by many low islands and cays, sunken reefs, and atolls awash, with reefs often rising abruptly from ocean depths greater than 1000m. There are few precise definitions, but Dangerous Ground corresponds roughly to the seas around the eastern half of the Spratly Islands. It is an oblong area running southwest to northeast for about 340 nautical miles (nm) (630 km), 175 nm (324 km) at its widest, with an area of about 52,000 nm² (178,000 km2). It is west of Palawan island and northwest of the Palawan Passage. It lies approximately between 7.5 and 12°N, 113–117°E. The US NGA literatureetc. seems to consider its centre as 10°N 115°E / 10°N 115°E. The area is poorly charted, making it exceptionally dangerous to navigate – the major Singapore-to-Hong-Kong routes go well to the west and east of the area. The Admiralty Sailing Directions give the following warning regarding navigation in this area: Due to the conflicting dates and accuracy of the various partial surveys of Dangerous Ground, certain shoals and reefs may appear on one chart, but not on another regardless of the scales involved.Charted depths and their locations may present considerable error in the lesser known regions of this area. Avoidance of Dangerous Ground is the mariner’s only assurance of safety. The water is a usually greenish-blue and is transparent to depths of 24–42 metres (79–138 ft) on clear days. (en)
- 危险地帶（英語：Dangerous Ground）是南中國海中一片存有眾多低岛（珊瑚岛）、沙洲、暗礁及淹沒於水中的環礁的大面積區域。其中的暗礁經常從超過一千米的水深急速上升。 危險地帶的地理範圍没有精确定义，但大致相等於南沙群岛東半部的周邊海域，即一个從西南到东北大约340海里（630公里）的长方形区域。最廣闊之處約175海里（324 公里），而面積約為52,000平方海里（178,000平方公里） 。它约位於北緯7.5–12°N、東經113-117°E，即巴拉望岛以西及巴拉望通道之西北。根據美國國家地理空間情報局文獻，其中心为 10°N 115°E / 10°N 115°E。 危險地帶的測量不完善和準確，故船隻在危險地帶中航行非常危險。新加坡到香港的主要航線皆選擇通過危險地帶以西 或東的海域。 《海军航行方向》 對通過危險地帶有以下警告: 「因為各次對危險地帶的測量的準確性有衝突，不論地圖的比例，一些暗沙和暗礁可能出現於一份地圖而不出現於另一份地圖中。於危險地帶較少人認識的區域中，暗沙和暗礁標示的深度和位置可能存在相当大的错误。 避免危险地帶是水手唯一保障安全的方法。」 於晴朗的日子，危險地帶中的海水通常呈綠藍色、並且透澈至24-42米（79-138呎）。 (zh)
