傻子’s从热液喷口到浮游生物的黄金

一张漂亮的小纸片 自然地球科学 有助于调和这个词的铁预算’的海洋。从热液喷口喷出的富含矿物质的热水含有大量的傻瓜’金或黄铁矿。由于黄铁矿比碱性铁更耐生锈,并且黄铁矿的大部分排气物质是纳米颗粒,因此在沉没和溶解之前,它们要分散很大的距离。使这一发现更为重要的是,铁通常是海洋浮游植物生长的限制因素。因此,热液喷口可能是世界上碳生产的间接但主要作用’s oceans.

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 上 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 上 National Public Radio, Discovery Channel, Fox News, 国家地理 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 上 the Web.
