Ocean under stress

Triple Trouble - Ocean Under Stress

Hot, sour and breathless Over the coming decades and centuries, ocean health will become increasingly stressed by at least three interacting factors. Rising seawater temperature, ocean acidification and ocean deoxygenation will cause substantial changes in marine physics, chemistry and biology. These changes will affect the ocean in ways that we are only beginning to understand.
It is imperative that international decision-makers and stakeholders understand the enormous role the ocean plays in sustaining life on Earth, and the consequences of a high CO2 world for the ocean and society.
Following awareness raising of ocean acidification at the United Nations Framework Convention on Climate Change meetings (2009 - 2015), the international partnership* is now highlighting its concern about the impacts of interacting stressors and have developed an Ocean Stress Guide.
This publication, coordinated by Plymouth Marine Laboratory, has received support from international organisations and programmes.

Ocean acidification: Connecting science, industry, policy and public

A powerful short film on Ocean acidification which brings together a wide range of stakeholders including, HSH Prince Albert II of Monaco, school children, a Plymouth fishmonger, a UK government Chief Scientific Adviser, representatives from industry and policy making departments, as well as a group of internationally recognised expert scientists.

Ocean Acidification: An Ecosystem Facing Dissolution

As a large sink, the ocean absorbs carbon dioxide from the atmosphere. But in sea water, the gas reacts to produce carbonic acid - a threat for organisms building their shells and skeletons from calcium carbonate. A film from GEOMAR | Helmholtz Centre for Ocean Research Kiel.


Testing the Waters (English Version)

Ocean acidification - known as "the other CO2 problem" - is now also affecting the ecosystems of the Mediterranean. The scientific project MedSeA, funded by the European Community, has been studying the impacts of the phenomenon throughout the Mediterranean region for the last three and a half years. The video shows key information, scientific knowledge, and findings of the MedSeA Project, against the beautiful (and endangered) setting of the Mediterranean waters.


BIOACID - Exploring Ocean Change

From the Arctic to the tropics, ocean acidification changes life in the sea. By absorbing carbon dioxide (CO2) from the atmosphere, the ocean slows down global climate change. But in seawater, the greenhouse gas causes a chemical reaction with far-reaching consequences: carbonic acid is formed, and the pH drops.

The German research network BIOACID examines the effects of acidification on the life and biogeochemical cycles in the ocean - and on all those who depend on it.
