Hello! I am a senior in the Environmental Geosciences major. I joined the Glacier Modeling lab last Spring semester, so I have now been a part of the lab for two semesters. I feel like I have come a long way from when I began my research here, and at the same time I still have a lot more to learn. I am becoming more and more familiar with using Google Earth Engine (GEE) and JavaScript in general. My goals for my future have slightly changed from when I started. I would still like to be involved with research in some aspect, but my plans for the near future are to get my masters studying sustainability.

Currently, I am looking at the Midgard glacier in Southeastern Greenland and figuring out when and why it separated into another glacier. I am doing this by studying the terminuses of Midgard each year and how they changed. I am working with a dataset of ice flow velocity. I was able to focus the data onto Midgard only by clipping the data to that region. Then I focused in on smaller areas of data, by creating buffers, at each terminus and one above the terminuses. Once I displayed, on the map, the terminuses’ position from 2000 to 2008, it appeared that there was a separation around 2005-2008. My next steps are to determine the exact date when this separation occurred and see if it has to do with the terminuses changing. I am working on getting the dataset into buffers that I created and plotting them in a chart.

This is Midgard glacier with an overlay of the velocity dataset. The points on the map are where I chose to put the buffers, and the squiggly lines are the terminuses.
A screenshot of the code I have generated so far. This is the summer Scene on the map. The code however is only showing the winter scene. Next step is creating an animation!

To share a little more information about me: I have five siblings, a kitty named George (who also goes by Mr. Kitty) and a doggo named Presley. Whenever I have free time, I enjoy (attempting to) drawing on my digital art tablet that I share with my younger sisters, reading books or webtoons, and of course walking Presley:)
