People of PACE: Bridget Seegers Sails the Seas… and Studies Them Too!

A woman stands on the left side of the image, seen from the waist up. She wears a white clean suit that covers her arms, torso, and over her head. She also has on a white mask that covers her nose and mouth and blue latex gloves. She is gesturing behind her and to the right of the image towards a large, rectangular piece of equipment - the PACE satellite. The side of the satellite visible is black and reflects light off it. Behind her and PACE is a large wall that has a green gridded pattern on it.

Bridget Seegers is an oceanographer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland and a team member for NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission.

A woman stands slightly to the right of center of the image. She is wearing a black T-shirt and has a hat on. She looks to the left of the image, out in the distance. She is standing on a boat and is holding the steering wheel in her left hand and rope in her right hand. Behind her is the ocean, part of a harbor, and a blue sky with some clouds.

What is your favorite atmosphere or ocean related book or movie?

“Life Aquatic” definitely comes to mind. It’s amazingly accurate in how it depicts certain aspects of life on a research vessel. For a book, there’s one called “The Long Way” by Bernard Moitessier. It’s about him sailing solo in a race around the world, way back in the day (1968), which is very interesting.

What is your research about?

I focus on harmful algal blooms. There are a lot of little, teeny organisms called phytoplankton in the ocean and lakes, and sometimes they grow into huge numbers, and we call that a bloom. That can be good because it feeds the food web, but sometimes it can be toxic and cause problems. People monitor those harmful events to reduce human exposure to any of the harmful toxins. I use satellites to monitor for these harmful events and help water quality managers respond to them.

A woman with curly blonde hair stands in the image seen from the knees up wearing black pants and a navy blue T-shirt with the words "PACE Launch Team" written on it. She is holding her right hand up in a "thumbs up" motion. Behind her and in the right side of the image are tall structures of a launch pad. A rocket is attached to one of the tall structures, the PACE logo printed at the top of it. The sky behind the launch pad and the woman is a gray blue color, filled with clouds.

What was your favorite part of watching the launch?

The PACE team, friends, and families being together sharing all the excitement, hugs, and emotions was my favorite part of launch. It was incredible watching the rocket light up the night as PACE began its journey to space! And, of course, fantastic to hear updates throughout launch and since that all is well with PACE and the instruments. All wonderful experiences!

What are you most looking forward to post-launch?

The data and exactly what we can do with it. There’s been a lot of talks and hopes of what this data will be like, but there’s never been a satellite like PACE. We can imagine all these products, but it’ll be great to see what we actually can do with the products. If we can tell one type of phytoplankton from another, we can hopefully tell some of the more harmful ones from ones that are just average members of the phytoplankton community that aren’t causing problems.

We know that OCI on PACE is going to be able to look at all the colors of the ocean, so what is your favorite color and why?

My favorite color is purple. Why? I don’t know, it just feels right.

Centered in the image is an aquatic creature - a Christmas tree worm. The magenta colored creature is in a spiral shape, spiraling upwards, where the diameter gets smaller as it rises - looking like the shape of a Christmas tree. Towards the center of the spiral, the color changes to a pale mint green.

Do you have a favorite type of phytoplankton or sea creature?

I think my favorite sea creature would be Christmas tree worms. They live on coral reefs and they like pop out and they look like an evergreen tree. They come in all these different colors. When you get close, they like pull themselves in, but then they pop back up. They’re really fun and colorful, and they’re kind of interactive. For phytoplankton, there are a variety of species that bioluminesce and I think that’s pretty magical when you see the ocean light up at night, either with breaking waves or running your hands through it.

A woman stands on a pale pink surfboard, riding in a wave. She wears a black wet suit which covers her legs, torso, and arms. Her hair is wet. She is facing the right of the image, while traveling towards the left. The water she is surfing on is a dark gray color, with a white wave break behind her. The sky is cloudy and gray.

What is a fun fact about yourself?

I like to sail. I had a friend who solo circumnavigated the globe, so I met him to sail in a variety of places like around French Polynesia, around nearly half of South Africa, and north of the Arctic Circle in this chain of islands called the Lofoten Islands. I was also able to surf north of the Arctic Circle from the sailboat!

What advice would you give to aspiring scientists who are looking to get where you are today?

A woman and two children are seen in the picture. The woman, with blonde curly hair, is to the left of the image, wearing a gray shirt with a NASA meatball logo on it. In the middle is a young girl wearing a purple shirt that says, "I want to be a princess and a physicist" with planets surrounding the words. To the right is a young boy with blond hair who wears a gray T-shirt with the NASA worm logo on it. He is reaching forward and holding a microscope.

Stay curious and be motivated by asking questions. Follow what interests you and what you’re passionate about. It’s not always a direct path and science can be a little bit tedious, so it’s really important to trust yourself and to pursue things that are interesting to you. Ask questions and don’t be afraid to chat with other scientists. Sometimes people think scientists are intimidating, but we’re mostly pretty nice and slightly awkward, so I would have those conversations!

What is one catch-all statement describing the importance of PACE?

Knowledge is power. For both PACE and science in general, the more information we have the better we understand things, and the more able we are to respond to the changing planet in an effective and meaningful way that empowers us.
