In 2009 two calibrated acoustic recorders were deployed in polar waters of the North Atlantic to study the seasonal occurrence of blue, fin, and sperm whales and to assess current ambient noise levels. Sounds from these cetaceans were recorded at both locations in most months of the year. During the summer months, seismic airguns associated with oil and gas exploration were audible for weeks at a time and dominated low frequency noise levels. Noise levels might further increase in the future as the receding sea ice enables extended human use of the area.
2009 年，两个经过校准的声学记录仪被部署在北大西洋的极地水域，以研究蓝鳍、长须和抹香鲸的季节性出现情况，并评估当前的环境噪声水平。在一年中的大多数月份里，这两个地点都能记录到这些鲸目动物的声音。在夏季，与石油和天然气勘探相关的地震气枪会连续几周都能听到，并且主导着低频噪声水平。随着海冰的消退，未来该地区可能会有更多的人类活动，这可能会进一步增加噪声水平。
