Iceland – In our last post, Team Geochemistry was getting ready to head to Iceland for some field work on volcanoes. Our goals were to map and sample volcanoes that erupted under glaciers, which have since retreated, exposing the pillow lavas and ash that formed when lava met ice. We met up with a research team from the Dickinson College Earth Sciences Department, and also brought Dr. Shelley Judge, Wooster’s structural geologist. Together, we collected over 30 samples, took 1000s of photos, flew the drone for 8 hours, and made 100s of structural measurements. Overall, it was a successful and productive field season, with some laughs along the way! Layali Banna, member of Team Geochemistry (and basalt goddess), describes their field experience.
[Guest blogger Layali Banna] Last week, team geochemistry went to Iceland. We met up with some old friends there, but we met some new ones as well. In total there were ten of us and we were ready to take Iceland by storm.
All of us walking along Undirhlíðar (from left to right: Phoebe, Dr. Edwards, Marisa, Dr. Judge, Dr. Pollock, Kendra, Layali and Ethan; Hannah Is behind the camera taking the photo.)
After a long day of flying we decided to mostly take it easy, just doing a short walk around a nearby quarry to learn more about what we will be looking for out in the field.

The second day was much different though – we spent almost all day out on Hannah’s site collecting samples for her project at Bræðravirki ridge. Divided into two teams, one group walked the ridge collecting samples, while the other group used a drone to map the ridge. This was a prime time up at the ridge since there was no snow cover, unlike past years where the gullies were hidden by snow, allowing us a great look at it without anything in the way.

A gulley on Bræðravirki that was buried in snow during past years was now accessible for sampling.
Our third day in Iceland after that long day in Bræðravirki we spent the morning inside working on our field books and collecting some data, making observations on our samples.
Everyone working together to look through all the samples we had collected the day prior.
The latter half of the day we surveyed Undirhlíðar and ended up goofing around a bit at a certain spot called the bowl.

After our half day we returned to Undirhlíðar. This time we were split up into three groups all doing different things in separate areas. One group mapped with drones, another analyzed and mapped deformation bands, taking samples and pictures of the bands, and the last group went and took samples for Marisa’s project.

Finally, on our last day in Iceland everyone was given a free day to do what they want, exploring some of the natural wonders the island has to offer as well as touring the capital of Iceland, ReykjavÍk.

The group stopped for some famous Icelandic street dogs in ReykjavÍk, Kendra is ready to dig in.
All too soon it was time for us to pack our bags and say goodbye to our friends and Iceland. It was time to head back to Wooster and work on the samples we collected in the lab.
Excellent post, Team Geochemistry! What a cool experience. I wonder if the surprising lack of snow cover on parts of the ridge is due to relentless climate change. Welcome back and good luck finishing your labwork this month.
