Gas on gas?

Science News,  July 28, 2007  by Fredric M. Blum

In view of the extreme importance of atmospheric carbon dioxide, I would have expected the momentous conclusion that southern oceans aren't absorbing the expected increased amount of C[O.sub.2], as well as the assertion that nutrient-enriched water absorbs C[O.sub.2] less effectively than leaner water does, to be confirmed by field observations. As presented, "Biological Hot Spots: Ocean eddies may not always lock away carbon" (SN: 5/1,9/07, p. 307) appears to represent nothing more than speculation.
