TL;DR: It is found that a large phytoplankton bloom over the Kerguelen plateau in the Southern Ocean was sustained by the supply of iron and major nutrients to surface waters from iron-rich deep water below, suggesting that changes in iron supply from below may have a more significant effect on atmospheric carbon dioxide concentrations than previously thought.
Journal ArticleDOI
Phytoplankton extracellular release and bacterial growth: dependence on the inorganic N: P ratio
TL;DR: It is concluded that P limitation provokes elevated PER m exponentially growing phytoplankton which is not utilized efficiently by the natural bacterial consortia which would allow the PER to coagulate and eventually form mucilage.
Journal ArticleDOI
Competition between biological and photochemical processes in the mineralization of dissolved organic carbon
TL;DR: The photo and bioreactive components of dissolved organic matter (DOM) from three different environments were determined during long-term decomposition experiments as mentioned in this paper, which demonstrated that biological and photochemical processes compete in the mineralization of DOC.
Journal ArticleDOI
Deciphering ocean carbon in a changing world
Mary Ann Moran,Elizabeth B. Kujawinski,Aron Stubbins,Rob Fatland,Lihini I. Aluwihare,Alison Buchan,Byron C. Crump,Pieter C. Dorrestein,Sonya T. Dyhrman,Nancy J. Hess,Bill Howe,Krista Longnecker,Patricia M. Medeiros,Jutta Niggemann,Ingrid Obernosterer,Daniel J. Repeta,Jacob R. Waldbauer +16 more
TL;DR: Questions being addressed using recent methodological and technological developments in analytical chemistry, microbiology, and informatics are considered and how these advances are transforming the authors' understanding of some of the most important reactions of the marine carbon cycle are considered.
Journal ArticleDOI
Contrasting effects of solar radiation on dissolved organic matter and its bioavailability to marine bacterioplankton
TL;DR: In this paper, the effect of ultraviolet radiation on the bioavailability of dissolved organic matter (DOM) to marine bacterio- plankton was investigated in the Mediterranean Sea (Strait of Gibraltar, South and North Aegean Sea) and in the Caribbean Sea off Curacao.
