Ocean Acidification
In November 2017, the German research network on ocean acidification BIOACID (Biological Impacts of Ocean Acidification) reaches its conclusion after eight years of extensive in [...] from 20 German institutions clearly indicate that ocean acidification and warming, along with other environmental stressors, impair life in the ocean and compromise important ecosystem services it provides

Ocean acidification
A new study in the prestigious journal Science Advances shows that stress from rising water temperatures reduces ability of corals to adapt to ocean acidification.

vulnerable to ocean acidification. The increasing amount of carbon dioxide in the atmosphere leads to an increased absorption of CO2 in the cold waters of the polar oceans and enhances the acidification there

A smaller ocean carbon sink can also be the outcome when climate changes affect major ocean currents, or when, due to changes in the marine environment (warming, acidification, nutrient and light [...] warming ocean simply can’t absorb as much as a cold one. In addition, the constant absorption of carbon dioxide affects the chemical balance of seawater. This phenomenon, referred to as ocean acidification [...] environmental scientist Dr. Judith, jpg | 14 MB Media Dialogue & Lectures Lectures | 06.11.2019 #Oceans4future?

in a changing Southern Ocean In large areas of the worlds oceans iron (Fe) limits primary production thus affecting the global carbon cycle. One such area is the Southern Ocean (SO). In addition to Fe [...] primary production with iron in the Southern Ocean. We will also address the question how Zn/Co/B12 co-limitation with iron is modulated by ocean acidification. To confirm Zn/Co/B12-limitation or co-limitation [...] trace metals and explore how these relationship may change with increasing CO2 and resulting ocean acidification. This multifaceted approach between laboratory experiments and field studies will shed light

In particular research on interactive effects of these factors is still missing. The
