Hydrological conditions are an important factor for aquatic ecosystems. Their contribution to stimulating phytoplankton bloom in eutrophic estuaries is not quite clear. We present the results of an outbreak of a phytoplankton bloom event observed in the eutrophic Razdolnaya R. estuary in 2022 from January 22 to February 23, when the estuary was covered by […]
Graphical abstract Highlights Abstract Since the industrial revolution, fossil fuel combustion has led to a 30 %-increase of the atmospheric CO2 concentration, also increasing the ocean partial CO2 pressure. The consequent lowered surface seawater pH is termed ocean acidification (OA) and severely affects marine life on a global scale. Cellular and molecular responses of marine species to lowered […]

Credit: David Barnes, British Antarctic Survey A new study led by the Institut de Ciències del Mar (ICM-CSIC), with colleagues from the British Antarctic Survey, the Institute of Oceanology, the Polish Academy of Sciences and the University of Gdańsk have also participated has revealed that global warming and ocean acidification threaten marine organisms that […]
The Southern Ocean is showing one of the most rapid responses to human-induced global change, thus acting as a sentinel of the effects on marine species and ecosystems. Ocean warming and acidification are already impacting benthic species with carbonate skeletons, but the magnitude of these changes to species and ecosystems remains largely unknown. Here we […]
Coccolithophores are unicellular photosynthetic plankton that perform extraordinary feats in ionic homeostasis to fabricate intricate nano-patterned plates made of calcium carbonate (CaCO3) crystals called coccoliths (1). Outside marine science communities, coccolithophores are less known than animal calcifiers such as shellfish or the cnidarians that form coral reefs. However, coccolithophores are one of Earth’s greatest biological […]
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 Scientific Committee on Oceanic Research (SCOR) was established by the International Council for Science (ICSU) in 1957 and is a co-sponsor of the international projects IMBER and SOLAS.

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.
