PhD Positions – Pollen-based Reconstructions of UV Radiation History Project detailsWe are seeking candidates for two fully funded PhD projects to develop pollen-based proxyreconstructions of relative changes in UV-B flux within the Holocene. Both projects will involve highresolutionsampling of lake sediment records for pollen, followed by FT-IR analysis to determineabundance of UV-B absorbing compounds (UACs) in the extracted pollen samples. One project willfocus on the record from a New Zealand site (Lake Ohau) and the other on the record from a site inTurkey (Nar Golu). The aim of both projects is to investigate nature and timing of variations in UACsin the context of changes in solar activity (e.g. grand maxima and minima) and other processeswhich may impact the levels of UV-B reaching the Earth・s surface. This research is part of a widerproject entitled ：Unlocking centuries・ worth of surface UV-B radiation hidden in pollen；, funded bythe Royal Society of New Zealand Te Ap.rangi Marsden Fund.LocationBoth positions will be based in New Zealand, at Massey University・s Palmerston North campus, inthe School of Agriculture and Environment. Depending on the conditions imposed by the ongoingCOVID-19 pandemic, candidates may be required to spend an extended period of time at theUniversity of Nottingham (Sutton-Bonington campus) in the United Kingdom.These positions are open to all domestic overseas applicants and international applicants currentlybased in New Zealand as well as those international applicants currently based overseas. Allinternational applicants currently based overseas should be aware that the New ZealandGovernment has placed restrictions on the borders, which may impact on their application.
