Journal ArticleDOI
Gas hydrate destabilization: enhanced dewatering, benthic material turnover and large methane plumes at the Cascadia convergent margin
Erwin Suess,Marta E Torres,Gerhard Bohrmann,Robert W. Collier,Jens Greinert,Peter Linke,Gregor Rehder,Anne M. Tréhu,Klaus Wallmann,Gisela Winckler,E. Zuleger +10 more
TL;DR: In this paper, the authors characterize a newly recognized mechanism of dewatering at convergent margins, where freshening of pore waters from hydrate destabilization at depth and free gas drives fluids upward.
Journal ArticleDOI
Covariant glacial-interglacial dust fluxes in the equatorial Pacific and Antarctica.
Gisela Winckler,Robert F. Anderson,Robert F. Anderson,Martin Q. Fleisher,David McGee,David McGee,Natalie M. Mahowald +6 more
TL;DR: Equatorial Pacific dust fluxes are highly correlated with global ice volume and withdust fluxes to Antarctica, which suggests that dust generation in interhemispheric source regions exhibited a common response to climate change over late-Pleistocene glacial cycles.
Journal ArticleDOI
The magnitude, timing and abruptness of changes in North African dust deposition over the last 20,000 yr
David McGee,Peter B deMenocal,Peter B deMenocal,Gisela Winckler,Gisela Winckler,Jan-Berend W Stuut,Louisa I Bradtmiller +6 more
TL;DR: In this paper, the authors present new records from a meridional transect of cores stretching from 311 Nt o 191N along the northwest African margin, which are able to document spatial and temporal changes in dust deposition under the North African dust plume throughout the last 20 ka.
Journal ArticleDOI
Increased Dust Deposition in the Pacific Southern Ocean During Glacial Periods
Frank Lamy,Rainer Gersonde,Gisela Winckler,Gisela Winckler,Oliver Esper,Andrea Jaeschke,Gerhard Kuhn,Johannes Ullermann,Alfredo Martínez-García,Fabrice Lambert,Rolf Kilian +10 more
TL;DR: Data sets of glacial-interglacial dust-supply cycles from the largest Southern Ocean sector, the polar South Pacific, are presented, indicating three times higher dust deposition during glacial periods than during interglacials for the past million years.
Journal ArticleDOI
Gustiness: The driver of glacial dustiness?
David McGee,David McGee,Wallace S. Broecker,Wallace S. Broecker,Gisela Winckler,Gisela Winckler +5 more
TL;DR: In this paper, a wide range of data supports wind gustiness as a primary driver of global dust levels, with steepened meridional temperature gradients during glacial periods causing increases in dust emissions through increases in the intensity and frequency of highspeed wind events in dust source areas.
