CO32- concentration and pCO2 thresholds for calcification and dissolution on the Molokai reef flat, Hawaii
K. K. Yates, R. B. Halley
2006, Biogeosciences (3) 357-369
The severity of the impact of elevated atmospheric pCO2 to coral reef ecosystems depends, in part, on how sea-water pCO2 affects the balance between calcification and dissolution of carbonate sediments. Presently, there are insufficient published data that relate concentrations of pCO 2 and CO32- to in situ rates of reef...

J.M. Guinotte, J.D. Bartley, A. Iqbal, D.G. Fautin, R. W. Buddemeier
2006, Marine Ecology Progress Series (316) 269-283
We demonstrate the KGSMapper (Kansas Geological Survey Mapper), a straightforward, web-based biogeographic tool that uses environmental conditions of places where members of a taxon are known to occur to find other places containing suitable habitat for them. Using occurrence data for anemonefishes or their host sea anemones, and data for...

Wall B.R. Graham, R. Girbacea, A. Mesonjesi, A. Aydin
2006, American Association of Petroleum Geologists Bulletin (90) 1227-1249
The process of fracture and fault formation in carbonates of the Albanides fold-thrust belt has been systematically documented using hierarchical development of structural elements from hand sample, outcrop, and geologic-map scales. The function of fractures and faults in fluid migration was elucidated using calcite cement and bitumen in these structures...

Developing a bubble number-density paleoclimatic indicator for glacier ice
M. K. Spencer, R. B. Alley, J. J. Fitzpatrick
2006, Journal of Glaciology (52) 358-364
Past accumulation rate can be estimated from the measured number-density of bubbles in an ice core and the reconstructed paleotemperature, using a new technique. Density increase and grain growth in polar firn are both controlled by temperature and accumulation rate, and the integrated effects are recorded in the number-density of...
