    Beschreibung: In order to investigate the spatial distribution of ö13C and 8180 of modern carbonate sedirnents on Great Baharna Bank, -290 surface sarnples were collected from a grid of stations approximately 10 km apart between 2001 and 2004. These samples were classified using a modified Dunham scheme, physically separated into six size fractions and subsequently analysed for their mineralogy (aragonite, low-Mg calcite and high-Mg calcite) and 813C and 8180 values. A striking feature of these data is the relatively positive 813C values of all the samples. Based on measurements of 813C and 8180 of the dissolved inorganic carbon and the water, most of the sediments can be considered tobe in C and O isotopic equilibrium with the arnbient waters. The high ö13C values are suggested to arise frorn isotopic enrichment of the dissolved inorganic carbon pool by photosynthesis of seagrasses, benthic algae and cyanobacteria on the platform and through the fractionation of HC03 - during the precipitation of calcium carbonate. Sediments that are not in C and O isotopic equilibriurn are dorninated more by skeletal material. The data showed an absence of significant spatial variation in 813C of the sediments on the Great Bahama Bank and no clear spatial patterns relative to the margin of the platform. The 8180 of the sediment showed more variation, with the interior sediments being isotopically enriched relative to the platform margin. The absence of signi.ficant variations in the ö13C in the modern surface sediments of Great Baharna Bank irrespective of facies type suggests that in the case of Great Baharna Bank, downcore variations in ö13C cannot be related to changes in facies.

    Beschreibung: Ocean circulation and global climate are strongly influenced by seawater density, which is itself controlled by salinity and temperature. Although adequate instrumental sea-surface temperature (SST) records exist for most of the surface oceans over the past 100-150 years, records of salinity really only exist for the last 40-50 years. Here we show that longer proxy records from corals (Siderastrea radians) in the eastern tropical North Atlantic are dominated by multi-decadal variations in salinity which are correlated with the relationship between SST and the North Atlantic Oscillation (NAO) over the course of the 20th century. The data reveal an increase in eastern tropical North Atlantic salinity of +0.5 psu between about 1950-1990. Rather than a monotonic secular increase, as indicated by some instrumental records, the pre-instrumental coral proxy records presented here suggest that salinity in the tropical North Atlantic is periodic on a decadal to multi-decadal scale.
