About Megan Hammond

I am a final year PhD student based in the geomagnetism laboratory at the University of Liverpool. I am studying sharp changes in geomagnetic field intensity and the possible links between field intensity, climate change and the collapse of civilized societies. I am so far mostly focused on using the microwave system based at Liverpool to determine the palaeointensity of archaeological samples from Turkey. I am currently working on samples from the Alalakh archaeological site in the Hatay Province as well as some mud bricks from the Oylum archaeological site in the Kilis Plain. My project partly stems from recent controversial work of Gallet et al (2006) who suggested that sudden sharp rises in geomagnetic field intensity in the past caused climate changes and major upheavals. An archaeomagnetic jerk represents a period of intensity maxima coinciding with a sharp cusp in field direction. Although my PhD is in archaeomagnetism I am interested in many aspects of geology particularly chemical geology, metamorphic assemblages and palaeontology and graduated from the University of Edinburgh in 2010 with a Masters of Earth Science. In my spare time I play many sports including Ultimate Frisbee and I enjoy reading and socialising.

So is this it, are we all going to die?

Today’s (7/7/2014) Metro newspaper has a nice article in the Metrocosm section by Ben Gilliland entitled “Portends of magnetogeddon” . Apart from the slight alarmism, it’s (as usual with Ben) pretty good, and I’m pleased to see him talk up … Continue reading

What is Archaeomagnetism?

For regular readers of this blog, the term “archaeomagnetism” will have been seen a number of times, most frequently in posts by me or Andy Herries! Archaeomagnetism is the study of burnt material found on archaeological sites. This can include … Continue reading

Magnetic Personalities – Reconstructing the field using ice cores

In the most recent Magnetic Personalities meeting we looked at a paper published in Quaternary Science Reviews in 2005 entitled “Geomagnetic Field intensity during the last 60,000 years based on 10Be and 36Cl from the Summit ice cores and 14C” … Continue reading

Archaeomagnetic fieldwork and experiments in France

In August/ September last year I was privileged to be invited to visit a French archaeological site in the midi Pyrenees in the company of Professor Philippe Lanos, director of archaeomagnetism research at the University of Rennes 1.  The archaeological site … Continue reading

Standing up for Science!

When not conducting experiments, carrying out fieldwork, attending conferences, reading papers or writing up, it’s nice to learn new skills and meet other PhD students and early career researchers. Laura and I achieved this last Friday by attending “Standing up … Continue reading
