GLERL Ocean(lake)ographer Eric Anderson on watching the Straits of Mackinac

Eric Anderson, GLERL oceanographer, used to study the movement of fluid inside bone tissue — now he studies the movement of water in the Great Lakes.

Eric Anderson is NOAA GLERL’s resident oceanographer (but his Twitter handle is @lakeographer—you should trademark that one, Eric). At its core, his research centers around the movement of water. You might have seen our animations of currents in the Straits of Mackinac, or of meteotsunamis coming across Lake Michigan — he’s the guy behind those computer models.

Some cool things about Eric are that he plays the banjo, that he used to study the movement of fluid inside bone tissue, and that he’s quick to remind us people were watching the Straits of Mackinac millennia before his computer models existed. Read on to learn more cool things!

How would you describe your job?

My research is on hydrodynamics, which is a fancy way of saying the moving physical aspects of the water in the Great Lakes—things like currents, temperatures, ice, and waves. Most of my day is built around looking at measurements of the water and air and then developing computer models that simulate how the lakes respond to different weather conditions. This field of science is particularly helpful in safe navigation of the lakes, responding to contaminant spills, search and rescue operations, and understanding how the ecosystem responds to different lake conditions.

What is the most interesting thing you’ve accomplished in your job?

Maybe the most rewarding has been working on the Straits of Mackinac. It’s one of the most beautiful spots in the Great Lakes, but also one of the most dynamic, with high-speed currents changing every few days, if not hours. A groundswell of attention to the Straits in the last several years has pushed the public to get more engaged and learn about the conditions in the Straits, and I’ve been glad to help where I can.

As part of this work, we’ve found some 1600’s-era [settler] written accounts of the currents in the Straits. We also know that [Indigenous] people have been watching the Straits for thousands of years, and it’s rewarding to continue this thread of knowledge.

What do you feel is the most significant challenge in your field today?

It seems like the hardest thing is to communicate the science. People are starved for information, and there’s a real love out there for learning about the Great Lakes. All we can do is to try and keep the flow of information getting out to the folks who care, and just as important, to those who don’t think they care. When you see environmental science covered in the news, it’s usually reporting on something negative or even catastrophic, which is certainly important, but there are pretty cool discoveries being made routinely, big and small, and those don’t often seem to make it to the headlines. We have to keep working hard to make sure these stories make it out, and at the same time keep our ears open to the concerns that people have for the lakes.

Where do you find inspiration? Where do your ideas come from in your research or other endeavors in your job?

Inspiration is everywhere. Try to hike up to a good vantage point overlooking the lake, like the dunes or a bluff, and not feel inspired. More often, though, inspiration comes from talking with other people, whether scientists, students, or interested members of the public. I can’t think of a time where I’ve given a public seminar and not walked away with a new question or idea to investigate. People’s enthusiasm and bond with the Great Lakes is infectious, and so I try to tap into that as often as I can.

Two meteotsunamis, large waves caused by storm systems, came across Lake Michigan on April 13, 2018. Eric Anderson models meteotsunamis in his role as oceanographer at NOAA GLERL.

How would you advise high school students interested in science as a career path, or someone interested in your particular field?

I took somewhat of a winding career path to get where I’m at with GLERL, working in car assembly plants and then on the nano-fluidic flow inside bone tissue before ending up in physical oceanography. I didn’t really know what I wanted in high school or college, but I knew physics and math were where I felt at home. So I found a way to learn the fundamentals that I’ve been able to apply in each of these jobs, and that allowed me to explore different parts of science and engineering. Not everyone will have the same chances or opportunities, but if you can find a way to really solidify the fundamentals and just as importantly seek out a breadth of experiences, you’ll be in a better position when those opportunities do come along.

What do you like to do when you AREN’T sciencing?

I’m either hanging out with family, playing music, or talking with someone about how I wish I was playing more music.

What do you wish people knew about scientists or research?

By and large, science is curiosity driven, often fueled by the scientist’s own enthusiasm, and in my case also by the interests of the public. Whether it’s a new discovery, or re-codifying or quantifying something that others have observed for millennia, there’s no agenda here other than to understand what’s happening around us and share whatever pieces we can make sense of. I’ll add a sweeping generalization that scientists love to talk about their research, so don’t be afraid to ask.

Women’s History Month Special: Retiring GLERL Physical Scientist Anne Clites gives us her parting wisdom

A woman with brown hair and a black vest on smiles for the camera.

Anne Clites, GLERL physical scientist, is retiring at the end of March after 35 years with the lab.

At the end of March, Anne Clites, GLERL physical scientist, will retire after 35 years with the lab. Her work can be somewhat behind-the-scenes (things like compiling, archiving and distributing data), but it’s just as essential as what our principal investigators do. She brings continuity, organization, and accountability. She’s contributed enormously to the science we do here, and we thought we’d ask her to share a bit of her wisdom and experience before she goes.

How would you describe your job? How long have you been doing it?

“I started working at GLERL in 1982. As a physical scientist, I’ve worked with a number of project scientists over the years, helping gather data, improve computer models, publish results, and make our products available and understandable to others. Most of the work has involved improving our understanding of the water budget, seasonal prediction of water levels and ice cover.”

Has your job changed over time?

“Technology has changed! When I started working at GLERL, I had to walk to another building to a card punch machine to run my programs. It was several years before we all had PCs on our desks. I was in on the effort to develop our first website and that has certainly changed the way we communicate and distribute data.”

What is the most interesting thing you’ve accomplished in your job? What has been your favorite part?

“I’m proud of my contributions to a lot of journal articles and data products over the years. I know that I’ve helped improve our website to make our data more discoverable. I’ve often felt like a translator between scientists and the public, and tried hard to build a bridge there when it was needed. I really love NOAA’s mission: ‘to understand and predict changes in climate, weather, oceans, and coasts’ and to share that knowledge with others. It’s important work and I’m proud to have a part in it.”

What advice would you give to young people who are beginning a career in science?

“Everyone should learn to write well! It is so important to be able to communicate what we learn – both with other scientists, and with the public. A good understanding of using data to tell a story won’t hurt, either.”

It’s Women’s History Month, and we’d love to hear some of your thoughts about being a woman in STEM. How do you think you’ve experienced your career differently than men you’ve worked with?

“I think family responsibilities are shared more now than they were 30 years ago, but I think women still do more of the mental juggling, although every family is different. One thing I truly valued about my job is that I had the opportunity to work part time while my kids were little. I was never treated as if my contributions were less important just because I worked part-time. That meant a lot to me. It also allowed me to be a Girl Scout leader, an active parent-teacher organization member and sports parent.”

What do you think the research/academic community can do to attract and retain women?

“Keep offering flexible work schedules and part-time work for women who want to juggle job and family.”

What do you like to do when you AREN’T sciencing?

“Cook, read, get outside, garden, sing, peace and justice work, board games, do anything with my kids and grandkids.”

What do you wish people knew about scientists or research?

“Too many people think of scientific research as something that will never touch their lives, and they are so wrong about that! We need facts to solve these problems! The Great Lakes hold 20% of the world’s available fresh surface water. That’s way too important to ignore!”

Scientists are people with questions: a conversation with GLERL limnologist Craig Stow

A man in a baseball cap stands in the GLERL lobby in front of some 3-d bathymetry maps of the Great Lakes

Craig Stow, a GLERL limnologist, says scientists are “people with questions.”

Craig Stow is a Limnologist (that means somebody who studies freshwater systems) at NOAA GLERL. He models nutrients cycling through (Great) lakes. His research is super applicable; notably, he’s part of the team trying to deal with nutrient loads in Lake Erie – he wrestles with the question of how much phosphorous is coming into the lake, and how it gets there.

Read on to see how Craig deals with mental blocks, why science isn’t like the movies, and what he thinks people get wrong about researchers.

How would you describe your job?

“I try to learn about things so that I can usefully apply any enhanced insight I might gain. Currently I’m trying to better understand the separate influences of tributary flow and tributary nutrient concentration on nutrient loads to Lake Erie. We have set new phosphorus load targets and those can be achieved by managing tributary flow, tributary nutrient concentration, or both, but the effects in the lake will differ in ways that are not obvious.”

What is the most interesting thing you’ve accomplished?

“The most interesting things are those that are counter to what you expect a priori. Though it can take a while to come to grips with the realization that you didn’t know what you were talking about at the outset. When I was a master’s student my adviser told me it was good to be humbled; I didn’t expect it to happen so frequently. Astounding revelations are more prevalent in movies than real life — at least in my office. Most of what I accomplish involves incremental insights that nudge the field along.”

Where do you find inspiration? Where do your ideas come from in your research or other endeavors in your job?

“Read a lot, talk to colleagues, recognize unresolved tensions, think really hard, then do something else. Good insights often occur when your mind relaxes following a period of intense concentration.”

How would you advise high school students interested in science as a career path, or someone interested in your particular field?

“Learn to write well. Publishing requires recognizing a good story and telling it effectively. If you can’t express your thoughts clearly and succinctly you will struggle in this field.”

What do you like to do when you AREN’T sciencing?

“I like to play and listen to music, work outdoors, be at home with the family, and grill. And think about fishing. I used to actually go fishing, now I just think about it. I’m usually more successful and don’t jab the hook in my fingers as often.”

What do you wish people knew about scientists or research?

“Science is the collective process of searching for the truth. It occurs by assembling and synthesizing information to generate ideas, and sharing those ideas so that others can corroborate, contradict, or modify them. The peer-reviewed literature is the primary venue for that process; that’s why publication is important. Scientists are the individuals who participate in this process. Most are intrinsically curious, many are really smart, some live an illusion of objectivity, and there are a few charlatans. The successful ones are more tenacious than anything else. There’s a tendency to view scientists as people with answers, mostly they’re people with questions.”
