Climate change is affecting the health and physiology of marine organisms and altering species interactions. Ocean acidification (OA) threatens calcifying organisms such as the Pacific oyster, Crassostrea gigas. In contrast, seagrasses, such as the eelgrass Zostera marina, can benefit from the increase in available carbon for photosynthesis found at a lower seawater pH. Seagrasses can […]
Naturally occurring microbial decomposition of organic matter (OM) in coastal marine environments cause increased acidity in deeper layers similar or even exceeding the future predictions for global ocean acidification (OA). Experimental studies in coastal areas characterized by increased inputs of OM and nutrients, coping with intermittent hypoxic/anoxic conditions, provide decrease. Laboratory CO2-manipulated microcosm experiments were […]
Understanding how marine organisms will be affected by global change is of primary importance to ensure ecosystem functioning and nature contributions to people. This study meets the call for addressing how life-history traits mediate effects of ocean acidification on fish. We built a database of overall and trait-mediated responses of teleost fish to future CO2 […]
Highlights • Ecotoxicological effects of elevated DIC were evaluated using 10 marine organisms. • Species-specific toxicity of elevated DIC were found with EC50 of 11–85 mM. • Mortality for copepod T. japonicus was the most sensitive endpoint for DIC toxicity. • Tentative criteria of DIC for protecting 80% of marine organisms is 11 mM. Abstract Recently, a novel […]
Previous work has not led to a clear understanding of the causes of spatial pattern in global surface ocean DIC, which generally increases polewards. Here, we revisit this question by investigating the drivers of observed latitudinal gradients in surface salinity-normalized DIC (nDIC) using the Global Ocean Data Analysis Project Version 2 (GLODAPv2) database. We used […]
The International Geosphere-Biosphere Programme (IGBP) was launched in 1987 to coordinate international research on global-scale and regional-scale interactions between Earth’s biological, chemical and physical processes and their interactions with human systems. IGBP’s international core projects Integrated Marine Biogeochemistry and Ecosystem Research (IMBER), Surface Ocean–Lower Atmosphere Study (SOLAS), Past Global Changes (PAGES) and Land–Ocean Interactions in the Coastal Zone (LOICZ) study ocean acidification.

Established by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1960, the Intergovernmental Oceanographic Commission (IOC-UNESCO) promotes international cooperation and coordinates programmes in marine research, services, observation systems, hazard mitigation, and capacity development in order to understand and effectively manage the resources of the ocean and coastal areas.

The Ocean Acidification International Coordination Center (OA-ICC) is operated by the International Atomic Energy Agency (IAEA)’s Environmental Laboratories in Monaco. An advisory board, including members of the SOLAS-IMBER Ocean Acidification Working Group (SIOA WG), provides recommendations to the project. The OA-ICC works in close collaboration with the Ocean Acidification international Reference User Group (iOA-RUG), a forum for dialogue between researchers and stakeholders. Contact: IAEA-Environment Laboratories, 4a Quai Antoine 1er, MC-98000 Principality of Monaco, Tel: +377 97977272, e-mail: OAICC.Contact-Point@iaea.org.
By the end of 2015 IGBP and its projects will be merging into a new international research initiative on global sustainability, Future Earth. Future Earth is a 10-year international programme that will provide critical knowledge required for societies to face the challenges posed by global environmental change and to identify opportunities for a transition to global sustainability.

There was an event when shower chairs are only used by old people and people with
actual incapacity. Happiness is multiplied when shared, so it is with the arrival of new baby that baby showers brings friends and
relatives together offering a emotional support to the parents and celebrating the occasion with
gusto. This make take a bit of background research because you want to be
sure you are speaking with someone who is giving
expert advice customized to the specific health
needs of your little one.
