First‐order reversal curve diagrams: A new tool for characterizing the magnetic properties of natural samples
- A. Roberts, C. R. Pike, K. Verosub
- Geology
- 10 December 2000
Paleomagnetic and environmental magnetic studies are commonly conducted on samples containing mixtures of magnetic minerals and/or grain sizes. Major hysteresis loops are routinely used to provide…

Characterizing interactions in fine magnetic particle systems using first order reversal curves
- C. R. Pike, A. Roberts, K. Verosub
- Mathematics
- 22 April 1999
We demonstrate a powerful and practical method of characterizing interactions in fine magnetic particle systems utilizing a class of hysteresis curves known as first order reversal curves. This…
Antarctic temperature and global sea level closely coupled over the past five glacial cycles
- E. Rohling, K. Grant, M. Kučera
- Environmental Science, Geography
- 21 June 2009
Sea level has varied by over one hundred metres across glacial–interglacial cycles over the past 520,000 years. An extended sea-level reconstruction shows a strong coupling between these sea-level…
Continental ice in Greenland during the Eocene and Oligocene
- J. Eldrett, I. Harding, P. Wilson, E. Butler, A. Roberts
- Environmental Science, GeologyNature
- 8 March 2007
The Eocene and Oligocene epochs (∼55 to 23 million years ago) comprise a critical phase in Earth history. An array of geological records supported by climate modelling indicates a profound shift in…
Three million years of monsoon variability over the northern Sahara
- J. Larrasoaña, A. Roberts, E. Rohling, M. Winklhofer, R. Wehausen
- Environmental Science, Geography
- 1 April 2003
Abstract
We present a 3 million year record of aeolian dust supply into the eastern Mediterranean Sea, based on hematite contents derived from magnetic properties of sediments from Ocean Drilling…
