Phytoplankton productivity and export sequester climatically significant quantities of
atmospheric carbon dioxide as particulate organic carbon through a suite of processes …

Compared with Phanerozoic strata, sulfate minerals are relatively rare in the Precambrian
record; this is probably due to the lower concentrations of sulfate in dominantly anoxic …

Stable barium isotopes are a potential proxy for riverine inputs into the ocean that reflect
monsoon variability and climate change. However, dissolved Ba isotope (δ138BaDBa) …

Abstract Coral Ba/Ca is a proxy for seawater barium concentration that varies with upwelling,
terrigenous input, and marine productivity whereas coral Sr/Ca varies with temperature. We …

The correlation between concentrations of dissolved barium (dBa) and silicon (dSi) in the
modern ocean supports the use of Ba as a paleoceanographic proxy. However, the …

Enabled by the success in the determination of stable barium (Ba) isotopic compositions in
seawater, Ba isotopes have been suggested as a novel tool to study physical and …

Deep-sea sediments highly enriched in rare-earth elements (REE), termed “REE-rich mud,”
have recently attracted attention as a potential mineral resource for industrially critical …

Oxygen is essential for marine ecosystems, and it is linked by respiration to carbon storage
in the deep ocean. Reconstructing oxygen concentrations in the past has been limited by the …

Future environmental change may profoundly affect oceanic ecosystems in a complex way,
due to the synergy between rising temperatures, reduction in mixing and upwelling due to …

Abstract The Neogene Lake Pannon was the largest lake that ever existed in Europe. It
attained its greatest extent during the Tortonian Thermal Maximum. For the first time, results …
