Understanding past changes in ocean, sea-ice and glacier variability in Northeast Greenland
Abstract:
Northeast Greenland has undergone significant changes in recent decades; marine terminating glaciers have retreated, sea-ice has declined in thickness and extent and ocean temperatures have warmed. However, our understanding of these changes and interactions are somewhat limited by the length of instrumental records. Using a multi-proxy approach on a marine sediment core, I will present a Holocene reconstruction of the changes to the Northeast Greenland Ice Stream and ocean currents. These reconstructions rely on a solid, regional understanding of these proxies. Therefore, analyses of benthic foraminiferal assemblages from surface samples in this region provide new insights into their distribution and use in paleo-reconstructions.
Bio:
I am a PhD student from the University of Aarhus, Denmark using marine sediment cores to understand how sea-ice, glaciers and oceans interacted throughout the Holocene. The aim of my research is to better constrain the timing and drivers of ice retreat and advance using a variety of proxies, including benthic foraminifera, sea-ice biomarkers and other sedimentological proxies. Alongside this, I have a particular interest in improving our regional understanding of these proxies (sea-ice biomarkers and benthic foraminifera) and their use in paleo-reconstructions around Greenland.
