Mid-Holocene sea-surface temperature reconstruction using fossil corals from Kume Island, Ryukyu, Japan
Holocene SST coral Sr/Ca East China Seatal proxy
2017/4/11
The relative warmth and stability of the Holocene was punctuated by several brief cold events. Whereas these cold
events on a global scale are widely reported, the lack of records from regions such a...
Intraspecific variation in Wenlock tabulate corals from Saaremaa (Estonia) and its taxonomic implications
Wenlock Baltoscandia tabulates intraspecific variation
2009/10/21
Different aspects of intraspecific variation in Wenlock tabulate corals are discussed. Intracorallum and intraspecific variation is demonstrated in specimens within the collection from one locality. T...
The worm endosymbionts in tabulate corals from the Silurian of Podolia,Ukraine
tabulate corals Chaetosalpinx endosymbiosis Silurian Podolia
2009/10/21
Two endosymbionts, Chaetosalpinx sibiriensis and Coralloconchus bragensis, occur in Silurian tabulate corals of Podolia. The endosymbiotic worms responsible for C. sibiriensis bioclaustrations in tabu...
Primary U distribution in scleractinian corals and its implications for U series dating
uranium diagenesis coral dating.
2014/4/9
In this study we use microsampling techniques to explore diagenetic processes in carbonates. These processes are important as they can affect the accuracy of U series chronometry. Fission track maps o...
Stable isotopes in deep-sea corals and a new mechanism for “vital effects”
Stable isotopes deep-sea corals new mechanism vital effects
2014/4/9
Offsets from isotopic equilibrium in biogenic carbonates have complicated paleoclimate reconstructions for decades. A new archive of climate, deep-sea corals, is used to evaluate the calcification pro...
