Alternative global Cretaceous paleogeography
Plate tectonic reconstructions for the Cretaceous have assumed that the major continental blocks—Eurasia, Greenland, North America, South America, Africa, India, Australia, and Antarctica—had
Oxygen isotope fractionation in marine aragonite of coralline sponges
Oxygen isotope values of the extant Caribbean coralline sponge Ceratoporella nicholsoni are compared with published temperatures and δ18O of water calculated from salinities. The measured values from
Cold-water coral growth in relation to the hydrography of the Celtic and Nordic European continental margin
TLDR
The data indicate that living cold-water coral reefs occur within the density envelope of sigma-theta (σΘ) = 27.35 to 27.65 kg m -3 , thus highlighting the importance of physical boundary conditions for cold- water coral growth and distribution.
El Niño variability off Peru during the last 20,000 years
Here we present a high-resolution marine sediment record from the El Nino region off the coast of Peru spanning the last 20,000 years. Sea surface temperature, photosynthetic pigments, and a lithic
Magnesium stable isotope fractionation in marine biogenic calcite and aragonite
This survey of magnesium stable isotope compositions in marine biogenic aragonite and calcite includes samples from corals, sclerosponges, benthic porcelaneous and planktonic perforate foraminifera,
Calcium isotope fractionation in calcite and aragonite
Abstract Calcium isotope fractionation was measured on skeletal aragonite and calcite from different marine biota and on inorganic calcite. Precipitation temperatures ranged from 0 to 28°C. Calcium
Phenotype-Specific Bacterial Communities in the Cold-Water Coral Lophelia pertusa (Scleractinia) and Their Implications for the Coral's Nutrition, Health, and Distribution
TLDR
Comparisons to other coral-bacterium associations suggest the existence of “cold-water coral-specific” bacterial groups sensu lato.
ENSO and Indian Ocean subtropical dipole variability is recorded in a coral record off southwest Madagascar for the period 1659 to 1995
The Ifaty coral record from off SW Madagascar provide a 336-year coral oxygen isotope record that is used to investigate the natural variability of the western Indian Ocean subtropical SST dipole and
Reconstructing seawater δ18O from paired coral δ18O and Sr/Ca ratios: Methods, error analysis and problems, with examples from Tahiti (French Polynesia) and Timor (Indonesia)
We compare several statistical routines that may be used to calculate delta O-18 and SSS from paired coral Sr/Ca and delta O-18 measurements. Typically, the delta O-18(coral)-SST relationship is
Evidence for preindustrial variations in the marine surface water carbonate system from coralline sponges
[1] Coralline sponge skeletons are excellent tools for reconstructing the carbon isotope history of dissolved inorganic carbon (DIC) in tropical surface waters. Carbon isotope records from coralline
