Late March is a pivotal time around the globe. It marks the start of spring in the Northern Hemisphere, and the coming of autumn in the Southern Hemisphere. In Antarctica, it’s when the sun drops below the horizon, not to rise again until the following September.
NOAA researchers at the South Pole Baseline Observatory continue their work through the long Antarctic night. NOAA Corps Lieutenant (junior grade) Nick Morgan, who works for the NOAA Earth System Research Lab, is spending a year there collecting data to help scientists better understand global climate trends.
The following interview with Lt. j.g. Morgan gives us a little insight into his work and what his life is like at the geographic South Pole.
Climate is a huge topic of discussion lately. For more than 50 years, researchers have been collecting data at the South Pole, such as carbon dioxide measurements and solar radiation — which makes them the longest running measurements of their kind.
Long term continuous data is important for climate studies to be able to pick out trends. On a short time scale, climate varies a lot and it's hard to see what's happening. The data that we collect is also used to improve climate models so that we can try to see changes in the future effectively.
I enjoy the fact that each air sample I take is more or less a part of history. These samples get added to a dataset that is used by scientists and governments around the world. There is a lot of satisfaction in knowing that there are some big environmental decisions that may be made in the future based on some of the data that I collected.
It's also quite an experience being able to spend a whole year at the South Pole!
Most of it is done in a lab environment. All though it could be said that just being in a place like Antarctica would be a field environment. We have very good facilities here though and the new Amundsen-Scott South Pole Station is very comfortable. We do spend some time outside though, launching ozonesondes and collecting air samples in flasks once a week. We also do a little bit of maintenance of our instruments located on the roof and meteorological tower.

Internet! Most of our data is collected and transmitted via satellite Internet. The only things that aren’t transmitted are the air samples that get collected and stored throughout the winter. They’re shipped back to the Earth System Research Laboratory (ESRL) in Boulder, Colo., upon station opening in October. If we were to lose the Internet, there would definitely have to be some changes to the way things operate around here.
It might be best to ask this question to the project leaders back at ESRL. I'm sure they have a long wish list. But things operate pretty efficiently around here. We have very little down time in collecting data. The Global Monitoring Division (part of ESRL) has a pretty extensive network of observatories but I'm sure there are some gaps out there that they would like to fill in. Especially over the oceans. Maybe putting an Atmospheric Baseline Observatory on every commercial shipping vessel would do the job!
I had an interest in weather and told my parents that I wanted to be a meteorologist since I was in grade school. When finishing up high school and looking at colleges, I decided that I wanted to study Atmospheric Science even though I wasn't really sure what I would do with the degree. I'm glad I did because it's worked out well for me.
After graduation I joined the NOAA Corps and have gotten to travel all over in support of science. My advice to anyone wondering what they should study when going to college would be to do something you have a passion for. The rest will work itself out.
The Exploratorium's Ice Stories Web site is great place to see what scientists do in the field. Granted it focuses on polar scientists, I would guess many of the experiences would be similar to those of other scientists. http://icestories.exploratorium.edu/dispatches/index.php
Easy. Living at the South Pole for a year.
I think it would be Jule Gregory Charney. He is the guy who derived the quasi-geostrophic potential vorticity equation that brought numerical weather prediction to life. Synoptic Meteorology was one of my favorite classes in college and QG theory is a big part of it. So I think it would have to be him.
Nick is in his third year as a commissioned officer in the NOAA Corps, one of America's uniformed services. Prior to joining the NOAA Corps, a passion for weather led to a B.S. in Atmospheric Science at the University of Wisconsin Milwaukee.
