8 p, 2.0 MB Destabilization of glacial climate by the radiative impact of Atlantic Meridional overturning circulation disruptions / Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Merlis, Timothy M. (McGill University. Atmospheric and Oceanic Science) ; Palter, Jaime B. (University of Rhode Island. Graduate School of Oceanography)
During each of the dramatic global warmings that ended the Pleistocene ice ages, the Atlantic Meridional Overturning Circulation (AMOC) was disrupted. It is not clear whether this was a contributing cause or simply an effect of deglaciation. [...]

The large peatland carbon stocks in the land use change-affected areas of equatorial Asia are vulnerable to fire. Combining satellite observations of active fire, burned area, and atmospheric concentrations of combustion tracers with a Bayesian inversion, we estimated the amount and variability of fire carbon emissions in equatorial Asia over the period 1997-2015.

5 p, 851.5 KB Instrumental validation of Globigerinoides ruber Mg/Ca as a proxy for NE Pacific summer SST / Mortyn, P. Graham (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Herguera, Juan Carlos (Centro de Investigación Científica y Educación Superior de Ensenada. Departamento de Oceanografía) ; Martínez Botí, M. A. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Accurate reconstruction of sea surface temperature (SST) is a high research priority, given that it is such a crucial variable in the Earth's climate system. The Mg/Ca composition of Globigerinoides ruber (white) has been calibrated and applied for a number of tropical and extratropical paleo-SST reconstructions, though validation studies of the proxy against instrumental observations are relatively scarce.

Here we present results from sediment traps that separate particles as a function of their settling velocity, which were moored in the Canary Current region over a 1. 5-year period. This study represents the longest time series using "in situ" particle settling velocity traps to date and are unique in providing year-round estimates. [...]
