PhD. Project: Reconstruction of climate change at sub-decadal
resolution from Mediterranean Sea sediment cores.
This Ph.D. project is part of the EUROCORES-EUROMARGIN project MOCCHA
(Multidisciplinary study Of Continental/ocean Climate dynamics using
High-resolution records from the eastern mediterraneAn (http://
moccha.html) involving the universities of Utrecht (G. De Lange),
Hamburg (G. Veersteeg) , Bremen ( K. Zonneveld) ETH. and will
involve participation to one or more research cruises in the
In this project we will study in detail two coring sites which
contain continuous high-resolution climate records. The first site is
located in the Gulf of Taranto. Preliminary studies of short cores
revealed the the presence of high-frequency 11-yr climate cycles over
the last last 4.000 years. Preliminary studies have revealed that
similar cycles occur at the second site, a deep anoxic basin in the
Ionian Sea site, were we also aim to complete an uninterrupted 11-
year sediment trap time series. Comparison of the deep-ocean anoxic
basin sites to the near-coastal sediments will allow to unravel land-
ocean interaction-dominated climate signals from typical deep-ocean
The successful candidate will investigate the oxygen and carbon
isotope composition of foraminifera and will apply the “clumped
isotope thermometer” based on the abundance of 13C-18O bonds in
carbonates to reconstruct temperature and salinity variations. The
project will be carried out in close cooperation with the other
groups which will use chemical analysis of benthic foraminifera (Mg/
Ca and Sr/Ca ratios); organic geochemical (Alkenone and TEX
paleotemperature proxies) and paleoproductivity proxies based on
organic microfossils on the same core material.
Candidates with a Masters or equivalent degree in geochemistry,
geology or environmental sciences are encouraged to apply.
Laboratory experience, particularly familiarity
with stable isotope techniques is desirable, but is not required.
Salary will be according to the Swiss National Science Foundation
rules. expected starting date is January 2008, negotiable.
