Posted on OA, 15 Dec 2016. The market squid, Doryteuthis opalescens, is an important forage species for the inshore ecosystems of the California Current System. Due to increased upwelling and expansion of the oxygen minimum zone in the California Current Ecosystem, the inshore environment is expected to experience lower

A small change with a large impact – mesocosm experiment reveals how community interactions amplify the response of a calcifying phytoplankton species to ocean acidification
Published OA 16 December 2016 The uptake of fossil fuel carbon dioxide (CO2) by the ocean increases seawater acidity and causes a decline in carbonate ion concentrations. This process, termed ocean acidification, makes it energetically more costly for calcifying organisms to form their calcareous shells and skeletons. Several studies have
Improved marine-derived POM availability and increased pH related to freshwater influence in an inland sea
Published 8 December 2016 Rapid changes, including warming and freshening, are occurring in coastal marine ecosystems worldwide. These environmental changes have the potential to alter ecosystem energetics by influencing availability of food sources and organism physiology. We investigated the influence of oceanographic variability on food availability and quality to benthic
Evaluating Carbonate System Algorithms in a Nearshore System: Does Total Alkalinity Matter?
Published: November 28, 2016 http://dx.doi.org/10.1371/journal.pone.0165191 Jonathan M. Jones, Julia Sweet, Mark A. Brzezinski, Heather M. McNair, Uta Passow Abstract Ocean acidification is a threat to many marine organisms, especially those that use calcium carbonate to form their shells and skeletons. The ability to accurately measure the carbonate system is the first step in
NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast
November 22, 2016 – For the first time, NOAA and partner scientists have connected the concentration of human-caused carbon dioxide in waters off the U.S. Pacific coast to the dissolving of shells of microscopic marine sea snails called pteropods. Commercially valuable fish such as salmon, sablefish and rock sole make the
