North Atlantic Deep Water formation initiated by the closure of the Barents Sea Seaway – a potential trigger for Antarctic glaciation
01/01/2017 - 31/12/2020

The Eocene-Oligocene Transition (EOT, ca 34-33 million years ago) was a
time of strong global cooling and the first occurrence of a
semi-permanent Antarctic ice sheet. Based on new proxy evidence we
propose here two novel hypotheses: 1) that isolation of the Arctic Ocean...


Warm and wet or hot and dry future Earth? The dual impact of CO2 in climate change explored with fossil plants
01/01/2017 - 31/12/2020

CO2 is a principal greenhouse gas that is increasing in the
atmosphere at an unprecedented rate due to human activity, causing
global climate change. It is predicted to continue to rise further and
result in a perilous temperature increase of up to 4°C by the ...


Climate-controlled mountain building: Tectonic consequences of the rain shadow in the Southern Alps of New Zealand
01/01/2017 - 31/12/2020



The Southern Alps of New Zealand are an archetypal example of a mountain range whose growth has been guided by the development of a rain shadow. By controlling growth and architecture of the evolving Southern Alps, the rain shadow e...


Late Quaternary chronology of Arctic Ocean sediments
01/01/2017 - 31/12/2020

This study will advance our ability to determine the age of Arctic Ocean
sediments, an effort needed to integrate Arctic paleoceanography with
other global paleoclimate data. The Arctic is a critical and sensitive
component of the global climate system. Many climate mode...


History and Stability of the Marine Cryosphere in Northwestern Greenland
01/01/2016 - 31/12/2019



This project will study the stability and deglacial history of the marine cryosphere in the area of Petermann Glacier, the largest point of ice drainage for the northwestern Greenland Ice Sheet. Petermann Glacier lost nearly 40% of ...


Climate instabilities during the last interstadial period - modelling and analyzing the sensitivity of the bipolar seesaw climate mechanisms along a global transect of sites
01/01/2016 - 31/12/2019
The end of the Last Ice Age, the ‘Last Termination’, was characterized by distinct climate shifts, which are documented in a variety of paleoclimate archives and proxies. With its markedly different boundary conditions (low sea levels, massive continental ice sheets) as comp...

Arctic Alaska & Eurasian Orogens
01/01/2015 - 31/12/2018
För flera hundra miljoner år sedan kolliderade urtida kontinenter för att bilda de kända eurasiska bergskedjorna: Uraliska bergskedjan, Kaledoniderna och Timaniderna. Utbredningen av Kaledoniderna och Timaniderna i Eurasien är välkänd, men i no...

The Coevolution of Life and Arsenic in Precambrian Oceans
01/09/2013 - 31/08/2018
The ubiquity of arsenic resistant genes across all of life's variety suggests a close intimacy between arsenic biogeochemistryand evolution, over geological time scales. However, the behaviour of arsenic in past environments where life originatedand its impact on our evolution is...

Carbonation of the Arabian Nubian Shield of Egypt: Implications for large-scale CO2 fluxes in the Neoproterozoic
01/01/2015 - 31/12/2017
Karbonatomvandling innebär att CO2-rika fluider reagerar med vissa bergarter i jordskorpan och manteln varvid omvandlingsreaktioner sker och karbonater fälls ut. Det är en viktig geologisk process med stor betydelse för att binda koldioxid i berggrunden, kolet...

Distinguishing Arctic CH4 Sources to the Atmosphere Using Inverse Analysis of High Frequency CH4, 13CH4 and CH3D Measurements: IZOMET-FS
01/01/2015 - 31/12/2017
Den pågående globala uppvärmningen förväntas bli mer omfattande i arktiska regioner än på andra ställen i världen. Metan (CH4), den näst viktigaste växthusgasen i atmosfären, har potentiellt stora men också os&a...
