Ocean acidification, increased glacial melting and changes in aerosol deposition are likely to impact concentration [...] micronutrients in seawater and will focus on biological production and degradation of ligands in polar oceans, their molecular composition, chemical properties and responses to changing environmental conditions

IPCC Climate Change Ocean acidification Anthropogenic climate change is altering the living conditions in the ocean more dramatically than in the past 50 to 300 million years. The oceans are becoming warmer [...] which chemically react with constituents of seawater, making the oceans more acidic. But that’s not all: for various reasons, warming oceans store less oxygen. In other words, they gradually lose their lifeblood [...] in the seas simultaneously reduces the number of safe havens remaining to them. Increasing ocean acidification puts organisms under additional pressure. Further, these three climate impacts are mutually

The availability of trace metals and light are considered key factors in controlling Southern Ocean phytoplankton [...] Polarstern expedition ANT XXVII-2. Picture: S. Trimborn (Photo: Alfred-Wegener-Institut) Southern Ocean phytoplankton are major drivers of global carbon cycling accounting for 20% of the global annual primary [...] information is available on how these environmental factors (trace metals, CO2, light) affect Southern Ocean phytoplankton. In particular research on interactive effects of these factors is still missing. The

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

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.
