oraneous marginal Hallstatt-Meliata Basin, located farther north, but are distinctly higher than those previously reported from the open ocean setting of the nearby Lagonegro Basin. The ~2 parts per mil offset represents a temperature differential of about 8 deg. Celsius, suggesting that sea surface temperatures along the northwestern margin (Sicani and Hallstatt Meliata basins) of the Tethys Ocean were lower than in the open ocean (Lagonegro Basin) during the lower part of Late Triassic. The cooler waters of the marginal basins have been interpreted to reflect coastal upwelling driven by strong monsoonal systems, found in existing paleoclimate models for the region.


Convection of North Pacific deep water during the early Cenozoic

Ashley M. Hague et al., Texas A&M University, Dept. of Oceanography, MS 3146, College Station, Texas 77843-3146, USA. Posted online ahead of print 10 April 2012; doi: 10.1130/G32886.1.

The ocean's deep-water (or "meridional overturning circulation" [MOC]), contributes significantly to transport of heat and nutrients and ventilation of the deep oceans, and is a crucial component of the climate system. In the modern mode, deep-water formation occurs in the North Atlantic as well as near Antarctica. However, a different mode likely operated during warm intervals of the past. The hypothesized modes of MOC include those characterized by high latitude Pacific sources, sinking of warm and salty waters in the subtropics, or widespread mixing across an overall weaker thermocline. Thus, determining how the deep ocean basins were ventilated in the past is necessary to address the role of deep-ocean circulation during fundamentally warm climate states. New proxy data, presented here by Ashley M. Hague and colleagues, from the North Pacific spanning the Late Cretaceous-Paleogene (~70-30 million years ago) combined with the results of coupled climate model simulations reveal a circulation mode characterized by
