离岸地震调查:安全,科学和研究

地震调查如何影响海洋生物?

在研究几十年的科学研究和现实世界经验后,联邦监管机构确定了这一点seismic surveysin the Atlantic OCS will have no measurable impact on fish or marine mammal populations.

  • In the海洋能源管理联邦局(Boem)的话“”出现了从地质和地球物理(G&G)地震活动中使用的空气枪的噪音没有记录的科学证据,对海洋动物种群或沿海社区产生不利影响。“
  • According to BOEM, seismic surveys in the Atlantic OCS “should not cause any deaths or injuries to the hearing of marine mammal[s] or sea turtles.”
  • Dr. William Brown, chief environmental officer for BOEM, told National Geographic that claims to the contrary are “wildly exaggerated and not supported by the evidence.”
  • While fish and some whales may swim away from an area and return after the survey vessel has passed, bottlenose dolphins are known to swim toward survey vessels to ride their bow waves.

尽管风险已经可忽略不计,但该行业遵循标准的操作程序,称为“缓解措施”,以便为海洋生物提供更多的保护。

  • 受过训练的保护物种观察员(PSO)是船上观看动物。如果某些海洋动物进入围绕操作系统建立的“排除区”,则运营停止,直到区域均清除至少30分钟。
  • 在开始地震调查时,运营商使用斜坡过程,逐渐增加所产生的声级,如果声级变得不舒服,可以让动物离开该区域。

目前的科学研究和研究是什么?

The best science and research indicates that seismic surveys have little-to-no impact on marine wildlife populations.

  • Based on both available scientific knowledge and operational experience, there is no evidence to suggest that the sound produced during an oil and gas industry seismic survey has resulted in any physical or auditory injury to a marine mammal.
  • 地震调查主要是低频率。并非所有海洋生命都听到同样的频率。就像人类一样,蝙蝠和狗的听到不同,一些海洋动物在较高频率下听到更好的频率,而其他海洋动物在较低频率下听到更好。
  • 最佳的科学信息还表明,海豚的任何声音相关损伤发生在高于地震调查产生的声音的水平。
  • 动物绞线可以出现多种原因,例如,疾病,迷失方向,自然死亡率,极端天气或伤害,但没有发现抗震调查没有相关性。

The industry remains committed to improving the scientific understanding of the impacts of our operations on marine life.

  • To provide the utmost safety precautions, seismic surveys in the U.S. Outer Continental Shelf are only conducted with measures in place to protect animals from high sound exposure levels.
  • 行业不断监督其缓解战略和基金研究的有效性,以更好地了解海上业务和海洋生物之间的互动,包括鱼类。
