Living at the edge of darkness, the community of microbes and tiny animals in the ocean’s twilight zone upcycle nutrients to ensure their survival. A study led by researchers at the University of Hawai‘i at Mānoa revealed that small, free-floating animals called zooplankton rely mainly on an even smaller class of organisms, called microzooplankton, to consolidate the sparse waste products in the water and transform it into higher-quality food. The study was published in Limnology and Oceanography.
New research published in Nature has revealed the importance of mineral forms of iron in regulating the cycling of this bio-essential nutrient in the ocean.
This summer marks year two of a three-year ASU BIOS study designed to expand understanding of how ocean eddies might be affecting coral reefs, as well as what role eddies may have played in reef accretion and overall functioning in the past.
