Dr. Jeremy Gabriel

Jeremy is a marine sedimentologist who specializes in palaeoenvironmental reconstruction of modern and ancient marine systems using a multiproxy approach including micropalaeontology, stable isotope geochemistry, and elemental composition analysis. His B.Sc and M.Sc. research involved reconstructing Holocene environmental changes within the submerged cave systems of a karst platform and for his Ph.D, he studied an Upper Cretaceous marine, muddy shelf deposit from the Western Interior Seaway of North America. In between his M.Sc. and Ph.D., Jeremy worked for 3 years for an environmental consulting company overseeing the coastal remediation of oil-impacted ecosystems along Saudi Arabia’s Gulf coast. Upon returning to Canada, he spent a year teaching introductory courses in earth science, physics, and chemistry at Quest University Canada in Squamish, British Columbia before starting his Ph.D in 2017. He joins the Department of Marine Geosciences as a Zuckerman Postdoctoral Scholar under the supervision of Dr. Beverly Goodman-Tchernov.

Current Research

Discerning between natural and anthropogenically-induced climate signals in the offshore Mediterranean sedimentary record using high-resolution elemental analysis

Supervisors: Beverly Goodman-Tchernov

The current sedimentary record contains an environmental signal that is comprised of both natural climate change and anthropogenically-induced changes resulting from the development and modification of feeder rivers and the coastal zone. Separating these two signals is crucial to modeling future climate change as well as understanding the local and regional impacts of fluvial and coastal zone modification. This research uses a high-resolution sampling (0.5-mm interval) technique to obtain the elemental composition of Mediterranean sediments and develop a chemofacies framework that will allow for greater correlation between inter- and intra-basinal cores and therefore a better understanding of the spatial extent of Holocene climate fluctuations.
