科学研究显示抹香鲸搁浅或与地磁异常有关

2017-09-07 07:01:41   新华网

《国际天体生物学杂志》近期发表的一项研究显示,大规模太阳风暴的干扰造成地球磁场异常,进而影响借助地磁场辨识方向的抹香鲸,这很可能是2016年初29头抹香鲸搁浅的原因。

去年年初不到一个月时间内,29头抹香鲸先后在德国、荷兰、英国及法国的海滩搁浅,引发公众关注。尸检结果显示,这些搁浅的抹香鲸“年富力强”、没有疾病,其搁浅原因让不少科学家产生研究兴趣。

英国广播公司5日报道,德国基尔大学克劳斯·范泽洛博士和他的同事提出一项研究假设:抹香鲸借助地球磁场“导航”,大规模太阳风暴的干扰造成地球磁场异常,进而影响抹香鲸辨识方向的能力。

范泽洛的研究团队发现,2015年年底发生两次大规模太阳风暴之后6周,人们在海滩发现了多头搁浅的抹香鲸。科学家由此认为这一研究假设成立,即抹香鲸搁浅与太阳风暴有关。

科学家也指出,抹香鲸可以感知挪威海域一带常规的地磁变化,这能防止它们误入北海。但大规模的太阳风暴会导致设得兰群岛至挪威一带的地磁场发生短期偏移,抹香鲸的这种能力会受到影响。

“出现北极光的地方通常是地球表面地磁干扰最明显的区域,”范泽洛告诉英国广播公司记者,“体态庞大的抹香鲸在深海中自由自在地游动,如果受到干扰,它们沿着错误方向游几天后会自行纠正。然而在苏格兰至挪威一带的海域,一旦抹香鲸沿着错误的方向游一两天,它们会发现已经来不及改变方向了。”

另有一些科学家指出,很难断定地磁异常就是造成抹香鲸搁浅的原因。美国国家航空航天局负责“太阳风暴对抹香鲸的影响”研究项目的专家指出,从数据分析角度看,并非单一因素导致抹香鲸搁浅。安蒂·普尔基宁博士表示:“应该从多个视角审视已经发生的事件。”

抹香鲸通常生活在温暖的深海中,大西洋东部的亚速尔群岛是它们的聚居地。当抹香鲸长到10岁至15岁,年轻的雄性抹香鲸会从英国、爱尔兰以西的海域游向极地,从而捕食鱿鱼。(包雪琳)【新华社微特稿】
