Grazing Limits Effects Of Ocean Fertilization

摘要

Preliminary results from a controversial Indo-German ocean fertilization experiment (LOHAFEX) have cast doubt on whether stimulating algal growth can help the sea sequester substantial amounts of carbon dioxide.rnEarlier this year, researchers aboard the German research vessel Polarstern (pictured) poured 20 tonnes of iron sulphate over a 300-square-kilometre area of the Southern Ocean around the Antarctic (see Nature 457,243; 2009).
