The Karst Research Group, directed by Professor Bogdan P. Onac in the School of Geosciences at the University of South Florida (USA) is recruiting a PhD student for a newly-funded NSF project that aims to provide Constraints on Last Interglacial and Late Holocene global mean sea level and fingerprinting polar ice mass flux from broadly distributed coastal caves.
Description
The scientific goals are encapsulated in several core research questions: 1) What is the temporal variability of GMSL from the LIG to the Late Holocene and what is the phasing between peak GMSL and the initiation of global scale warming; 2) What are the relative contributions of the major polar ice sheets to this variability and is there evidence of hemispheric teleconnections? and 3) To what extent is the GMSL rise and acceleration anomalous relative to the record of GMSL across the Late Holocene? All sea level work will be conducted on existing and newly collected phreatic overgrowths on speleothems from sites that include Mallorca, Sardinia, Croatia, Cuba, and Mexico.
Tasks
As part of this project, the PhD student will perform a combination of field work, U-series datings, and numerical modeling of gravitationally self-consistent sea-level change, mantle convection, and dynamic topography in collaboration with a well-rounded supervisory team. Work for this project will be carried out in collaboration with Prof. Yemane Asmerom and Dr. Victor Polyak (University of New Mexico in Albuquerque) and Prof. Jerry Mitrovica (Harvard University). The candidate is expected to publish three papers out of her/his dissertation.
Requirements
A background in cave and karst geology and familiarity with radiogenic and stable isotope geochemistry, carbonate petrology, and paleoclimatology would be ideal for this position, but any candidates with a demonstrated ability to quickly get up to speed in these fields will be considered.
Applications
The positions will remain open until filled, but to be guaranteed consideration, applications should be received by October 15th, 2022. The PhD program would start on January 9, 2023 and is fully funded for 4 years.
Application deadline
Further information
Interested candidates should contact Prof. Onac directly (bonac@usf.edu) with an email explaining educational goals and research experience, along with a CV (including 2-3 referee information) and a Cover Letter (this can include: a description of why you want to undertake a PhD in this field and a list of prior publications or other writing sample).
