在海洋中追寻喷气孔就象在大海中捞针一样,但1984年5月在该区进行调查的科学家认为沿果尔达(Gorda)海岭可能存在两个喷气孔,该海岭为俄勒冈沿海的一个海底扩张海岭.在美国国家洋海及大气局的船上,研究队从该海岭北端的两个海域收集了海水样品,这些样品显示出一些接近热液作用的指标:高度富集的锰、铁微粒和溶解了的氦气(Rh).俄勒冈州立大学海洋化学家RobertCollier说:“我们尚未发现任何喷气孔,但我们找到了有力的证据”.据Collier提供,这两个采样区的锰含量高于正常海水的10倍,并可与在胡安·德.福卡(Juan de Fuca)海岭附近5公里内发现的喷气孔对比.目前,研究
Tracing air jets in the ocean is like finding a needle in the sea, but scientists investigating the area in May 1984 found that there may be two jet holes along the Gorda Ridge, a ridge off the coast of Oregon At the United States Oceanic and Atmospheric Administration, the team collected seawater samples from two sea areas at the northern end of the ridge and showed some proximate hydrothermal targets: highly enriched manganese, iron particles and Dissolved helium (Rh). “Ocean State researcher Robert Collier of Oregon State University said:” We have not found any air jets yet, but we found strong evidence. "According to Collier, the manganese content of both sampling areas was higher than normal 10 times the seawater, compared with the jet holes found within 5 km near the Juan de Fuca ridge.
