Seaweed and seagrasses

This study showed the effects of ocean acidification on ecosystems at coastal sites where volcanic CO2 vents lower the pH of the water. Along gradients of normal pH (8.1–8.2) to lowered pH (mean [...]

A brown seaweed (Fucus vesiculosus) grew more slowly in ocean acidification conditions. Consumption of the seaweed by an isopod (Idotea emarginata) was not affected by ocean acidification or [...]

Growth rate and biomass of a seaweed (the red alga Chrondrus crispus) increased only when ocean acidification was accompanied by warmer temperatures. Photosynthesis was reduced under ocean [...]

The amount of available phosphorus appeared to regulate how much inorganic carbon was used by a red alga grown at different levels of ocean acidification conditions. Growth reflected a balance [...]

The combined effect of ocean acidification and rising temperature enhanced the sensitivity of a red alga to ultraviolet (UV) radiation. This was reflected in an increased damage rate, decreased [...]

Eelgrass was able to photosynthesize better under ocean acidification conditions because of increased availability of carbon dioxide. The results suggest that ocean acidification may [...]

This four-page brochure provides an introduction to ocean and coastal acidification, its effects on marine life, why the Northeast is especially vulnerable, research [...]
