海洋’最不高产水域正在扩展

ResearchBlogging.org.您可以正确阅读这篇文章的标题和原始纸张。 Brian H.今天向我送了这篇文章。使用来自最后九年来的Seawifs数据Polovina等。表明,在北部和南太平洋和大西洋地区的低表面叶绿素每年都在扩大0.8-4.3%。这些区域替代了具有低表面积的较高的表面叶绿素。这些领域的总扩展等于660万平方公里(大约2/3的美国大小)。下图显示了北太平洋(B)北大西洋(B)第1季度的表面叶绿素的面积叶绿素的区域和回归线,(a)北大西洋中的第1季度,(c)南太平洋四分之一的3,你可以清楚地看到增加。地图低于折叠。真的,真的坏消息

低叶绿素水域的膨胀与基于中纬度的垂直分层增加的全球变暖场景一致,但我们观察到的扩张率大大超过最近的模型预测。

显然,在深处找到食物越来越难。

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://jiaxiangsuji.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
