Laboratory life: my work experience week at BGS

My week began with a welcome tour of the research facilities at BGS and, more specifically, the geochemistry laboratories. The team provided an introduction to the field of mass spectrometry and the use of isotopes in archaeological research. The sample preparation, which happens under very precise, controlled conditions to exclude contamination, involves a huge amount work prior to analysis. It wasn’t long before I was gaining hands-on experience working with carbon isotopes from organic and inorganic materials, preparing samples and then analysing them on mass spectrometers. For me, one of the highlights was learning how to handle samples down to 40 micrograms in weight — which I can confirm is difficult to see with the naked eye!  

Geoarchaeology 

Dr Angela Lamb is well known for being one of the leading geochemists on the research into and analysis of King Richard III’s remains. She took the time to talk to me about the relevance and application of geochemistry in archaeological contexts. In relation to King Richard III, her detailed analysis has revealed various fascinating details about his life, for example that he lived in different locations through his childhood and into his adult years. Bones in our bodies reflect our diet and location (due to the underlying geology that creates different soil chemistries in different areas) and this type of analysis has been used in countless archaeological investigations — as featured in the TV programme Digging for Britain!  

The BGS collections 

I was also taken on a tour of the BGS collections by Louise Neep. It was so exciting to see them in person, especially the vast fossil collections. Louise explained how conservation methods have evolved since the 18th century. I was able to see fossils that are up to 500 million years old and inspected ancient plants, trilobites and an ichthyosaur. It was thrilling to hold such ancient relics in my hands. Louise gave me a real appreciation for all the curation efforts that are taken by BGS staff members like Louise to preserve the relics for future scientific research.  

The week ended with an excellent conversation with Dan Condon, who works on dating meteorites. He explained how uranium–lead dating is used and the physics and chemistry involved, which was particularly relevant to my aspirations to be an astrophysicist.  

Overall, this was a very informative and exciting week that introduced me to various facets of laboratory life, which is very different to what we see at school. It has enhanced my understanding of which skills are essential for laboratory work, for example the high-precision, detail-oriented work on the samples, and the importance of handling scientific data. The week made me appreciate science methods and gain confidence that research in astrophysics is the ideal career for me.  

Thanks 

Thanks to all the staff at BGS who were very helpful, especially Charlotte Hipkiss, Jack Lacey, Kotryna Savickaite, Diksha Bista, Dan Condon, David King, Doris Wagner and Carol Arrowsmith.
