美國研究初步證實,60年前丟棄在夏威夷歐胡島西岸的軍事武器對大眾和環境不具立即傷害性。2002年美軍潛水人員在該區已找到約2000堆的廢軍武,2006年在該海岸附近又尋獲九個之前先前沒發現的軍武。
這個搜尋研究是由美國國防部要求和贊助,以響應當地居民的關切。參與調查的科學家來自國家海洋大氣行政部門(NOAA),夏威夷大學和夏威夷土地和自然資源部門。
2006年6月中,科學家花費兩週仔細搜尋普凱灣(Pokai Bay)周遭5海浬地區。居民稱該區為大砲珊瑚礁(Ordnance Reef),珊瑚礁遍佈在水面下約10到70公尺(40到225英呎)深。
此調查確認放置在該地的武器包括小型到大型投射性武器及海軍槍枝砲彈。抽樣魚種則沒有檢測到相關爆炸物質。除了銅之外,該區沈積物樣本中的金屬含量普遍較低。
Preliminary data from a study of military munitions dumped in the sea off the west coast of Oahu 60 years ago show they pose no immediate danger to the public or the environment. Nine clusters of munitions not previously identified were found near shore in addition to about 2,000 munitions found in the area by U.S. Army divers in 2002.
Requested and funded by the Department of Defense, DoD, the study was conducted in response to the concerns of local communities. Scientists from the National Oceanic and Atmospheric Administration, NOAA, the University of Hawaii, and the Hawaii Department of Land and Natural Resources participated.
For two weeks in June 2006, scientists combed an area of five square nautical miles off Pokai Bay, just offshore of the town of Waianae, known locally as Ordnance Reef. This reef lies in water approximately 10 to 70 meters (40 to 225 feet) deep.
The survey verified the presence of munitions ranging from small arms projectiles to large-caliber artillery projectiles and naval gun ammunition.
No explosives or related compounds were detected in the fish samples taken during the survey. With the exception of copper, metal levels in sediment samples from the study area were low overall.
