Reconstructing past ocean physical properties

During the summer holiday, I took part in a research placement with Dr Pallavi Anand in the School of Environment, Earth and Ecosystem Sciences at the Open University, organised by the Nuffield Foundation. The placement involved coding a MATLAB toolkit to a more accessible program such as Python that would use paleoclimate data to solve for past seawater temperature, oxygen isotope and salinity.

Geochemistry of the deep-sea mud to understand Monsoon

This summer I went on a research experience placement with The Open University’s School of Environment, Earth and Ecosystem Sciences (EEES). This was a seven-week project, funded by NERC (Natural Environment Research Council).

The project was to assist in a calibration of results obtained from deep-sea core sediment samples from two different sites around the Bay of Bengal.

The calibration is part of a wider project that my colleague, Emmeline Gray is working on for her PhD. This is looking at how the Indian Summer Monsoon (ISM) behaved during a past warm period (similar to predicted future conditions) by observing how certain parameters in the sea floor sediments at these sites vary over time. This could give an insight as to how climate change might affect our oceans over time.

Supporting a Nuffield Research Student

Over the summer, I mentored a Nuffield Research Student.

I was originally interested in getting involved in the scheme to gain experience in teaching and mentorship.

The student, Zaibaa, worked to complete a pilot study, the results of which are now actively informing my PhD research direction.

My time mentoring Zaibaa was really valuable; it challenged me to teach the scientific method of hypothesis testing to someone else.

Further to this, I gained experience in project management and how to give feedback – which was harder than I thought!

I’d highly recommend other PhD students consider designing and mentoring a Nuffield student in the future, particularly if you’re interested in gaining experience of supervising projects.

Dr Pallavi Anand (project providers) supported my work as my PhD supervisor. I’m grateful for the the opportunity and funding from Nuffield Foundation.

Fishing in the Atlantic!

During my summer holidays, after my first year at college, I took part in a Nuffield research placement at the School of Environment, Earth and Ecosystem Sciences (EEES) at the Open University.

During this placement, I worked alongside a PhD student Sophie Alexander to analyse marine sediment (or mud in simple terms).

The main aim was to investigate surface ocean productivity in the Southern and Atlantic Ocean during the early Eocene. This was broken down for me into smaller aims as below:

  • Create smear slides of mud samples from different sites
  • Identify components on slides using a polarising microscope
  • Compare analysis of 3 different sites and decide what changes there are and how they were caused
  • Use the data gained to improve knowledge of ocean productivity during a warm greenhouse period.
