The Intra–Americas Seas region is known for its relevance to air–sea interaction processes,
the contrast between large water masses and a relatively small continental area, and the …

Dissolved oxygen (O2) is essential for most ocean ecosystems, fuelling organisms'
respiration and facilitating the cycling of carbon and nutrients. Oxygen measurements have …

Archaeal membrane lipids are widely used for paleotemperature reconstructions, yet these
molecular fossils also bear rich information about ecology and evolution of marine ammonia …

Paleotemperature proxy data form the cornerstone of paleoclimate research and are integral
to understanding the evolution of the Earth system across the Phanerozoic Eon. Here, we …

Paleoceanographic studies addressing the oceanographic variability in the western sector
of the subtropical South Atlantic-especially those focused on the Brazil Current (BC) and on …

Abstract The late Miocene-early Pliocene biogenic bloom was an extended time interval
characterised by elevated ocean export productivity at numerous locations. As primary …

Sparassodonts were the apex mammalian predators of South America throughout most of
the Cenozoic, diversifying into a wide array of niches including fox-like and even saber …

The meridional variability of the Subtropical Front (STF) in the Southern Hemisphere, linked
to expansions or contractions of the Southern Ocean, may have played an important role in …

The marine biological pump is crucial for removing excess carbon dioxide from the
atmosphere to the ocean interior and seafloor sediments. The Late Miocene Biogenic Bloom …
