North Atlantic Climate and Cryosphere Variability Over the Past 20,000 Years

Creator:

Sinclair, Gaylen

Abstract:

Reconstructing the sensitivity of past climate to forcings, and of ancient glaciers and ice sheets to this climate, can allow us to better understand the range of climate and cryosphere behavior we may see in the coming centuries. The Arctic is a region of particular importance due to its well-documented...

ABSTRACT OF THE DISSERTATION OF Gaylen Sinclair for the degree of Doctor of Philosophy in Geology
Earliest Holocene south Greenland ice sheet retreat within its late Holocene extent

Creator:

Carlson, Anders E., Winsor, Kelsey, Ullman, David J., Brook, Edward J., Hood, Dylan H., Axford, Yarrow, LeGrande, Allegra N., Anslow, Faron S., and Sinclair, Gaylen

Abstract:

Early Holocene summer warmth drove dramatic Greenland ice sheet (GIS) retreat. Subsequent insolation-driven cooling caused GIS margin readvance to late Holocene maxima, from which ice margins are now retreating. We use ¹⁰Be surface exposure ages from four locations between 69.4°N and 61.2°N to date when in the early Holocene south...
