A new field, new country, and new data

I have found that change, risks, and being outside your comfort zone is where the magic happens in life. As Alan Watts said, “The only way to make sense out of change is to plunge into it, move with it, and join the dance.” After leaving my comfortable and steady job as a data analyst this past summer, I dove into a series of changes as I started my journey as a Ph.D. student.

Embarking on my new adventure of starting a Ph.D. program, fortunately, began with an exciting opportunity to travel internationally, help colleagues with their research, and get my first hands-on experience with paleoclimate research. Both my master’s and bachelor’s degrees were in biology, but after learning about paleoclimate several years ago, I decided to change gears (and dive head first) into a new field of research for my Ph.D. Beginning my doctoral experience with hands-on lab work in a country I had never been to was really exciting.

Ice core science is commonly an international effort due to the challenging logistics of retrieving and storing polar ice cores and the variety of skills required to analyze them. The OSU Ice Core & Quaternary Geochemistry Lab has close colleagues at the University of Copenhagen at the Niels Bohr Institute Physics of Ice Climate and Earth. I had the opportunity to help those folks with an extensive gas measurement “campaign” (i.e., an extended period of time collecting measurements) and also learn a lot about the lab techniques I will use in my own research.

The ice used in the campaign was from Northeast Greenland in an area of fast-moving ice called an ice stream. Collecting ice from this region allows researchers to uncover how the ice stream may contribute to sea level rise and reveal past climate. The gas extracted from the ice core is derived from small bubbles locked in the ice, revealing past atmospheric conditions. (For more information on the project, check out the EastGRIP website). During the campaign, we had a team of 5-8 scientists running a continuous analysis of the dust and gas content of the core and also collected meltwater from the ice to examine the water chemistry at a later date.

An ice core melting on a hot plate continuously. Meltwater is collected through a series of tubing and instruments which can then extract the gas, count dust particles, and collect meltwater.

The campaign needed lots of hands on deck to take measurements continuously throughout the day. This approach allows for precise and high-resolution measurements. Ice was prepared and continuously melted on a heated platform. The meltwater then flowed through a series of systems that measured dust and gas and exported the meltwater to be analyzed later. Our time was spent diagnosing issues with a complicated and specialized system, cutting and preparing ice in a -15°C freezer, monitoring the measurements, and collecting discrete meltwater samples.

Serendipitously, while I was there doing ice core science, the University of Copenhagen celebrated the 100th birthday of Willi Daansgard, a Danish pioneer in ice core science. The university held a three-day symposium hosting ice core science talks and celebrating Daansgard’s achievements in ice core science. I was really excited and thankful to learn about the rich history of this field I have just joined.

Aside from the research, Copenhagen taught me the joy of commuting by bike, and I immediately bought a bike first thing when I got back to the U.S. Exploring castles and palaces, and biking around exploring the city was a fun way to spend the evenings. This trip was a great adventure experiencing a new country and learning about the new field I am so excited to now be a part of.
