Declining coral calcification on the Great Barrier Reef.
Science, Vol. 323, pp. 116 - 119, 2 January 2009.
DOI: 10.1126/science.1165283
Reef-building corals are under increasing physiological stress
from a changing climate and ocean absorption of increasing atmospheric
carbon dioxide. We investigated 328 colonies of massive Porites corals
from 69 reefs of the Great Barrier Reef (GBR) in Australia. Their skeletal
records show that throughout the GBR, calcification has declined by 14.2%
since 1990, predominantly because extension (linear growth) has declined
by 13.3%. The data suggest that such a severe and sudden decline in
calcification is unprecedented in at least the past 400 years.
Calcification increases linearly with increasing large-scale sea surface
temperature but responds nonlinearly to annual temperature anomalies.
The causes of the decline remain unknown; however, this study suggests
that increasing temperature stress and a declining saturation state of
seawater aragonite may be diminishing the ability of GBR corals to
deposit calcium carbonate.
