In a vast ocean, studying impact of the tiniest creatures

Vast portions of the oceans contain low levels of the nutrients that normally sustain life. Yet these areas are not devoid of life. Once thought to be biological deserts, recent research has shown that such nutrient-poor marine systems could significantly contribute to the amount of carbon dioxide that is trapped into the deep ocean, influencing Earth's climate. It is critical to improve our understanding of the biogeochemical functioning of these vast ocean environments, in order to accurately
