Dear OOI Community, As many of you may now be aware, the U.S. National Science Foundation (NSF) has initiated a major descoping of the Ocean Observatories Initiative (OOI) Major Facility. The official...

Circumpolar Deep Water is increasing in thickness towards Antarctica in the upper 2000 m of the Southern Ocean, according to analyses of ship-based observations combined with machine learning modellin...

We analyze modern leaf waxes in near-shore marine sediments spanning a north–south transect along the coast of western North America Leaf wax hydrogen isotope values become more negative at the l...

When atmospheric carbon dioxide levels decline, increased ocean heat absorption would initially slow surface warming before warming the deep ocean, which ultimately raises global mean surface temperat...

Ice sheets can be extremely sensitive, or remarkably resilient, to environmental perturbations. Reconstructions of past ice sheet variability help identify what controls their stability and how they m...

Large benthic oxygen isotope fluctuations in the Oligocene Southern Ocean primarily represent deep water temperature changes, suggesting the Antarctic ice sheet volume was relatively stable, according to a clumped isotope record.

Abstract. The ratio of the trace element Mg over Ca (Mg/Ca) and the oxygen isotopic composition (δ18O) of foraminiferal calcite are widely employed for reconstructing past ocean temperatures, although...
