Posted on OA: 16 Apr 2015 The Bering Sea and Gulf of Alaska support a number of commercially important flatfish fisheries. These high latitude ecosystems are predicted to be most immediately impacted by ongoing ocean acidification, but the range of responses by commercial fishery species has yet to be

Experimental ocean acidification alters the allocation of metabolic energy
T.-C. Francis Pan1, Scott L. Applebaum1, and Donal T. Manahan2 Department of Biological Sciences, University of Southern California, Los Angeles, CA 90089 — www.pnas.org/cgi/doi/10.1073/pnas.1416967112 Energy is required to maintain physiological homeostasis in response to environmental change. Although responses to environmental stressors frequently are assumed to involve high metabolic costs, the biochemical bases
Detecting changes in marine responses to ENSO from 850 to 2100 C.E.: Insights from the ocean carbon cycle
Posted on OA: 9 Apr 2015 It is open whether El Niño–Southern Oscillation (ENSO) varies under climate change and how potential changes in the marine system are detectable. Here differences in the influence of ENSO on biogeochemical tracers, pH, productivity, and ocean temperature are analyzed in a continuous 850–2100
Sea change: What took decades to destroy took millennia to recover
Posted on The Davis Enterprise: 5 Apr 2015 — By Kat Kerlin — The study by UC Davis scientists,, published online Monday in the Early Edition of the journal PNAS, is the first record of disturbance and recovery of seafloor ecosystem biodiversity in response to abrupt climate change. Ocean
Oceans Are Losing Oxygen—and Becoming More Hostile to Life
Posted on National Geographic: 13 Mar 2015 — By Craig Welch — Low-oxygen areas are expanding in deep waters, killing some creatures outright and changing how and where others live. It may get much worse. The diving patterns of Atlantic sailfish, like this one going after sardines in the Caribbean,
