Improving ocean research and mapping

Published 6 January 2017   Federal reports advance knowledge and describe actions to address ocean acidification and ocean and coastal mapping. This Administration has strongly supported science and interagency coordination, across government and with academic, industry, and other stakeholders, to address societal needs and inform effective ocean management. Today, the Office

Species-Specific Responses of Juvenile Rockfish to Elevated pCO2: From Behavior to Genomics

Published: January 5, 2017 Read the original post for the complete article and all diagrams and figures: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0169670 Abstract In the California Current ecosystem, global climate change is predicted to trigger large-scale changes in ocean chemistry within this century. Ocean acidification—which occurs when increased levels of atmospheric CO2 dissolve into the

Metabolic cost of calcification in bivalve larvae under experimental ocean acidification

Published OA 13 December 2016 Abstract: Physiological increases in energy expenditure frequently occur in response to environmental stress. Although energy limitation is often invoked as a basis for decreased calcification under ocean acidification, energy-relevant measurements related to this process are scant. In this study we focus on first-shell (prodissoconch I) formation in

Competitive fitness of a predominant pelagic calcifier impaired by ocean acidification

Published 16 December 2016   Coccolithophores—single-celled calcifying phytoplankton—are an important group of marine primary producers and the dominant builders of calcium carbonate globally. Coccolithophores form extensive blooms and increase the density and sinking speed of organic matter via calcium carbonate ballasting. Thereby, they play a key role in the marine carbon
