Stable Isotopic And Trace Metal Analyses Of Two Porites Lobata Colonies - Oahu, Hawaii: Implications For Past Seasonal Variation And Sea Surface Temperatures And Anthropogenic Effects On The Reef Environment, Jonathan Macdonald
Geology Theses and Dissertations
Corals from the western and equatorial Pacific Ocean have been extensively studied for the purposes of generating paleoclimate reconstructions spanning the last several hundred years. However, in the central subtropical North Pacific, there are currently few published coral records extending beyond 10 to 20 years. The hermatypic coral species Porites lobata and Porites lutea have proven to be useful indicators of paleoclimate and past sea surface conditions at other locations. Here I have analyzed two Porites lobata coral cores collected from colonies from opposite sides of Oahu, Hawaii to assess their utility for developing multi-decadal length climatic reconstructions in this …
Assessing The Paleoclimatic Utility Of The Indo-Pacific Coral Genus Diploastrea In A 225-Year Oxygen Isotope Record From Fiji, Stefan Bagnato
Assessing The Paleoclimatic Utility Of The Indo-Pacific Coral Genus Diploastrea In A 225-Year Oxygen Isotope Record From Fiji, Stefan Bagnato
Geology Theses and Dissertations
In the Western Pacific there remains, both spatially and temporally, a sparse record of surface ocean conditions and very few long paleoclimate records able to extend our understanding of this important region. The coral genus Porites is the common coral currently used for Pacific paleoclimate studies and has proven to be very useful. The massive coral Diploastrea, due to its slow growth rate and dense structure, may preserve temporally longer geochemical proxy records than Porites colonies of the same length. Its long lifespan and fossil history give this genus great potential; however no assessment has been made of the paleoclimatic …
