Elliot is a postdoc at Trinity College Dublin, working on the geochemistry of the North Atlantic Igneous Province. He recently spent 2 months aboard R/V JOIDES Resolution as part of IODP Expedition 390 and will tell anyone who will listen. You can find him on twitter @elliotjcarter

5 things I learnt from 2 months at sea with the International Ocean Discovery Program

This year I was lucky enough to be part of International Ocean Discovery Program (IODP) Expedition 390 – South Atlantic Transect I – aboard the research vessel JOIDES Resolution which spent two months, from April to June, out in the South Atlantic, drilling into and sampling the upper oceanic crust and sediments. I sailed as a petrologist and was responsible for describing how the basa ...[Read More]

The strangest rock you’ve probably never heard of

The strangest rock you’ve probably never heard of

In this blog I’m going to talk a bit about one of my favourite rocks – the strangest rock you’ve probably never heard of – listvenite. Listvenite (sometimes spelt listwanite or listwaenite) is the product of a chemical reaction between peridotite and carbon dioxide, and it is truly strange! I first came across listvenites working on the Semail Ophiolite, Oman, during my PhD. The Semail Ophiolite i ...[Read More]

Exploring parachute science in analytical geoscience

Crater lakes, Kelimutu Volcano, Indonesia.

During this past October, a team of researchers took part in a “hackathon” organised by the UK Natural Environment Research Council (NERC) to generate data and new ideas to increase diversity in geoscience. This was an extremely hectic, sometimes stressful but fun and illuminating experience which ultimately culminated in a pilot funding bid (which we learned this week has been successful!). Our i ...[Read More]

Drilling in the deep: Project Mohole and the underground space race

The drilling derrick on DV Chikyu

The mantle makes up the bulk of Earth, extending from near the surface to the edge of the core 2900 km down. It constitutes 84% of Earth’s volume and has roughly 6 times the mass of Mars! Despite its impressive bulk, the mantle is almost everywhere covered by several km of crust. As a result we don’t have a lot of pieces of it that we can look at, hold or study. Those we have (e.g. xenoliths ...[Read More]
