The oceanic gateways of the Drake Passage and the Agulhas Current are critical locations for the inflow of intermediate-depth water masses to the Atlantic, which contribute to the shallow return flow that balances the export of deep water from the No...

Plant macrofossil and biomarker evidence of fen-bog transition and associated changes in vegetation (2014)
Journal Article

Past vegetation assemblages, preserved in peat layers, are one of the key proxies when reconstructing historical peatland dynamics. Northern peatlands can be divided into two main types: fens and bogs. Compared with bog peat, the fen peat is usually...

Persistent warmth across the Benguela upwelling system during the Pliocene epoch (2014)
Journal Article

A feature of Pliocene climate is the occurrence of “permanent El Niño-like” or “El Padre” conditions in the Pacific Ocean. From the analysis of sediment cores in the modern northern Benguela upwelling, we show that the mean oceanographic state off So...

Palaeoclimate reconstructions reveal a strong link between El Niño-Southern Oscillation and Tropical Pacific mean state (2013)
Journal Article

Palaeoclimate reconstructions reveal a strong link between El Niño-Southern Oscillation and Tropical Pacific mean state. Nature Communications, 4(11), Article 2692. https://doi.org/10.1038/ncomms3692

The El Niño-Southern Oscillation (ENSO) is one of the most important components of the global climate system, but its potential response to an anthropogenic increase in atmospheric CO2 remains largely unknown. One of the major limitations in ENSO pre... Read More about Palaeoclimate reconstructions reveal a strong link between El Niño-Southern Oscillation and Tropical Pacific mean state.

On the identification of a Pliocene time slice for data-model comparison (2013)
Journal Article
Haywood, A., Dolan, A., Pickering, S., Dowsett, H., McClymont, E., Prescott, C., …Valdes, P. (2013). On the identification of a Pliocene time slice for data-model comparison. Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 371(2001), Article 20120515. https://doi.org/10.1098/rsta.2012.0515

The characteristics of the mid-Pliocene warm period (mPWP: 3.264–3.025 MaBP) have been examined using geological proxies and climate models. While there is agreement between models and data, details of regional climate differ. Uncertainties in prescr...

The n-alkane and sterol composition of living fen plants as a potential tool for palaeoecological studies (2013)
Journal Article
Ronkainen, T., McClymont, E., Väliranta, M., & Tuittila, E. (2013). The n-alkane and sterol composition of living fen plants as a potential tool for palaeoecological studies. Organic Geochemistry, 59, 1-9. https://doi.org/10.1016/j.orggeochem.2013.03.005

In groundwater-fed fen peatlands, the surface biomass decays rapidly and, as a result, highly humified peat is formed. A high degree of humification constrains palaeoecological studies because reliable identification of plant remains is hampered. Org...

Interglacial intensity in the North Atlantic over the last 800,000 years: investigating the complexity of the mid-Brunhes Event (MBE) (2013)
Journal Article

The mid-Brunhes Event (MBE) represents a step-like increase, between Marine Isotope Stages (MIS) 13/11, in the intensity of interglacial warmth. A transect of palaeoclimatic records in the North Atlantic from 40°N to the Nordic Seas indicates strong...

The mid-Pleistocene climate transition (MPT) is defined by the emergence of high amplitude, quasi-100 ka glacial-interglacial cycles from a prior regime of more subtle 41 ka cycles. This change in periodicity and amplitude cannot be explained by a ch...

Two major types of glycerol dialkyl glycerol tetraethers (GDGTs) are commonly used in paleoecological and paleoclimatological reconstructions: isoprenoidal and branched GDGTs. In aquatic environments, it was originally assumed that isoprenoidal GDGTs...
