Title“The Southern Ocean reveals its climate secrets: Paleotemperature insights from marine sediments”

Time: 14:00-15:00

Place: Room 215, Ocean Building
    
Amelia’s research  is divided into three focus areas: 1) Cenozoic climate
evolution/Antarctic cryosphere development, 2) Role of the high-latitude
oceans in Glacial-Interglacial carbon cycling, and 3) Antarctic Holocene
climate variability.

    She mainly uses  inorganic (trace elements in foraminifers and marine
sediments, 14C, diatom δ30Si, foraminifer δ18O and δ13C) and organic
(lipid biomarker) geochemical techniques and micropaleontologic analyses as
appropriate to the processes she is investigating. My multi-proxy approach
enables me to address a broad range of climate and biogeochemical problems.
