Our planet’s lifeline

August 28, 2023

The 120-year-old ASU Bermuda Institute of Ocean Sciences continues to dive into ways to support ocean health

Editor's note: This story originally appeared in the fall 2023 issue of ASU Thrive magazine.

In the clear blue waters of the Sargasso Sea swim all sorts of marine life: eels, white marlin and whale sharks; turtles, manta rays and even humpback whales. The sea, a region in the Atlantic Ocean that encompasses the Bermuda islands, is a hotbed of biodiversity. 

But on the back of the Atlantic Explorer — a 170-foot-long research vessel owned and operated by the Bermuda Institute of Ocean Sciences, a unit of the Julie Ann Wrigley Global Futures Laboratory at ASU — second-year PhD student Yuuki Niimi hopes to catch much smaller creatures: zooplankton.

It’s the middle of the night because that’s when zooplankton swim from the ocean’s depths to the water’s surface to feed on phytoplankton. But it’s not completely pitch-black; there are lights on the ship and flashing green strobe lights on the nets being towed in the water, which temporarily blind the zooplankton, making them easier to catch.

It can be a bit scary, Niimi admits: The back of the ship, where the mechanism to lower the nets into the water sits, can flood with seawater. The nets are heavy. The boat shakes. But it’s worth it once he and his fellow researchers pull up a net to see a new world.

“The first time you bring up a net, everybody’s like, ‘What is that? That’s so weird!’” says Amy Maas, an assistant professor in the School of Ocean Futures and an ASU BIOS faculty member, who has been on research cruises with Niimi.

“It looks like a busy city, but in three dimensions, or like a galaxy spinning around. You’ve got all these different shaped things — and none are shaped like us; they’ve got too many legs or no legs at all — and they’re zooming around in this bucket,” Maas says. 

On his first research cruise, in July 2021, Niimi remembers Maas and Leocadio Blanco-Bercial — another ASU BIOS researcher and assistant professor in the School of Ocean Futures — easily identifying the different zooplankton. 

But he was confused: Was that thing zooming around in the net a krill or a shrimp? The two can look similar, but krill, zooplankton also called euphausiids, have exposed gills, though you need a microscope to see that. Eventually, after multiple research trips and nights spent studying in the ship’s lab, Niimi became adept at identifying krill and pteropods. 

“I can just look at it with my naked eye and say, ‘That’s this genus,’ or ‘That’s this species,’” he says. 

What were once just “specks of dust” were now distinct creatures — each playing an essential role in the ocean’s overall health.

The importance of plankton

Zooplankton are tiny organisms that range from a fraction of a millimeter to centimeters in length and take a variety of shapes. Krill look like tiny shrimp; copepod can resemble insects, with a pair of antenna atop their teardrop-shaped bodies; and pteropods, planktonic marine snail, are called “sea butterflies” because their foot resembles two wings. Then there’s phytoplankton, the microscopic algae that zooplankton feed on and which photosynthesize in the top layers of the ocean.

Though they might be small, the role plankton play is enormous. 

“Zooplankton are the most abundant animals on Earth, by far, and they are sustaining all the trophic webs in the oceans,” Blanco-Bercial says. 

They’re also the first step in the biological carbon pump, the crucial ocean system that sequesters carbon out of the atmosphere and stores it in the deep ocean. 

“We need to know the crucial roles of these different zooplankton so that we know, as the ocean is changing, how the biological carbon pump may be changing.”

The pump works like this: First, phytoplankton capture carbon dioxide through photosynthesis. 

“Think of the equivalent of grass on land. That’s what phytoplankton are in the ocean,” says Susanne Neuer, founding director of the School of Ocean Futures and a professor in ocean biogeochemistry and one of Niimi’s advisors. 

Then, the phytoplankton die and begin to sink, or they get eaten by zooplankton, which excrete fecal pellets containing organic carbon that sink even deeper. Those zooplankton die or get eaten by bigger predators themselves — and sink. As the organic carbon sinks and sinks, it gets stored for longer and longer. It can stay sequestered for up to 1,000 years if it reaches the deep ocean.

What Niimi, Neuer and others are trying to figure out is what zooplankton are out there, where they are going, how much they’re excreting and how much carbon or other nutrients are in all those sinking particles. After they collect the zooplankton, one experiment involves putting them in beakers and seeing just how many fecal pellets they produce and what’s in them. Understanding their vital roles in the carbon cycle is part of a puzzle.

The oceans take up about a quarter to a third of all our emissions through this carbon pump. Without it, we would have already surpassed the 1.5 degree Celsius target from the Paris climate agreement, Neuer says. 

“The ocean is buying us time,” Neuer says. And that time is thanks to plankton. 

But while the ocean helps stem climate change, it’s being affected by it. The researchers are studying the biological carbon pump because the seas are changing, already getting warmer and more acidic. 

“We need to know the crucial roles of these different zooplankton so that we know, as the ocean is changing, how the biological carbon pump may be changing,” Neuer says, who is the principal investigator in the project. 

Partnering for the oceans

Neuer started working with scientists at ASU BIOS about 15 years ago. ASU BIOS itself has been doing oceanography work for 120 years. U.S. scientists first visited it in 1903, and it has run long-term studies for years — like its Bermuda Atlantic Time-series Study, which has collected data on the ocean’s physical, biological and chemical properties through cruises out to sea every month since 1988. As Neuer and Niimi have done, other researchers can access that trove of historical data and piggyback onto those cruises for their work. 

“That saves a lot of time, money and headaches, to know that those data exist,” Blanco-Bercial says, “and then you can focus on the question you want to answer.” 

In 2021, ASU and BIOS joined forces, turning the Bermuda institution into a center for the Julie Ann Wrigley Global Futures Laboratory, alongside ASU’s Center for Global Discovery and Conservation Science in Hawaii. 

“The merger between BIOS and ASU opens up ocean sciences for ASU students,” Neuer says, including opportunities for field experience and the chance to work with the faculty in Bermuda.

Andrea Brenner, a first-year PhD student in Neuer’s group who went on a research cruise with Niimi in the summer of 2022, and again in March 2023, has experienced the partnership’s benefit firsthand.

“I remember being on the ship and watching (Maas and Blanco-Bercial) empty the buckets attached to these nets, collecting these teeny tiny little things,” she says of her first cruise. 

She watched them pick out these organisms without knowing what they were herself, learning on the go. But then, in their first class, Maas and Blanco-Bercial had more time to explain the types of plankton species and how they differ. 

“It was very cool to see how I saw these species on a ship a couple of weeks ago, and now I’m learning about them in a classroom,” Brenner says.

ASU BIOS faculty are also aware of the difference having that connection to ASU’s campus can make. To William Curry, ASU BIOS president and CEO, bringing the ocean to ASU students, particularly through its online and hybrid programs, was a huge appeal.

“The online aspect and the flexibility of that kind of educational programming are really important when you’re on this little rock out in the middle of the North Atlantic,” Curry says. 

Looking ahead

Oceans cover over 70% of our planet. Their health irrevocably intertwines with Earth’s health. There’s much work to do to better understand the oceans and how climate change affects them.

One priority Curry has for ASU BIOS, in addition to the already extensive plankton research and its decades-long time series research projects, is to increase its robotics operations. The institution already uses underwater gliders that take measurements using sensors, moving up and down the water column (and yes, sometimes they bump into marine life, even getting bitten by sharks). ASU BIOS has used these since 2014 to monitor the delivery of nutrients to the surface of the ocean, which limits and controls the surface productivity in the Sargasso Sea. 

Ocean stats

One important discovery is the observation of a significant spring increase in turbulence caused by marine organisms, which increases nutrient delivery and biological productivity. Curry says it’s time to expand on taking more of the ocean’s vital signs with additional robotics.

“The future of observing the oceans is in autonomous robotics and sensor systems to provide continuous observations of important biogeochemical processes over broad areas of the oceans, something that cannot be achieved by the few numbers of ships in the research fleet,” he says. 

Beyond learning about the ocean, ASU also has the opportunity to help protect it — and our planet. 

The Global Futures Laboratory focuses not just on research and education, Curry says, but on solutions. “(They’re) trying to figure out not just what will higher CO2 do to the planet, but how can we affect it or stop it or mitigate it better?” 

Some answers, at least, likely lie underwater.

Story by Dakota Webber, assistant director of career readiness at the West campus for Career Services.

In today’s world, technology can dominate conversations about necessary skills for today and tomorrow. These indeed are crucial skills, but what about the nontechnical core skills needed to flourish in an ever-evolving world?

Navigating the world of work means strengthening skills such as communication, equity and inclusion, and leadership — timeless for succeeding no matter how technology-driven workplaces become. The beauty of these core skills is that they transfer across any industry and any organization.  

Our team in Career Services has explored skills employers look for in our workforce. Our work is guided by the career competencies defined by the National Association of Colleges and Employers, as well as through interviews with employers across the Valley. 

Let’s dive into three core skills to master for your career success.

Skill 1 – Critical thinking

Critical thinking involves analyzing data or information to find solutions to challenges. In the workplace, this might involve taking the appropriate course of action in a stressful work situation such as when a doctor must triage a patient in the emergency room. Another example could be an engineer having to decide what materials should replace an older material in an elevator. 

You can exercise this skill by using articles that include graphs or numerical data; practice making sense of the data. What does this data suggest? How can you determine if this data is reliable? How do you find out if the data is free of bias? Then identify a problem that the data might help illuminate. What solutions might the data suggest?

Critical thinking happens every day, and as you practice in a more intentional, focused way, you will be able to identify solutions, then communicate these more effectively. And you’ll be able to articulate the value you bring to your work.

Skill 2 – Innovation

Innovation is the ability and process of generating or approaching existing ideas in new ways. Every employer is looking for the next big idea or creative solution, and you can impress your supervisors and co-workers by leveraging this skill. A great example of innovation is Dreamscape Learn at ASU. The university identified a need for virtual reality learning driven by immersion and storytelling and found a way to create and implement this learning-by-experiencing example into the classroom.

Practicing innovation in your life starts with identifying areas of need in your workplace or community. For example, if you have noticed that there is an issue with littering in your neighborhood you can collaborate with your neighbors to organize a weekly cleanup day — or brainstorm even more effective ways to reduce the problem. Once you’ve identified challenges, you can take risks and collaborate on solutions.

“Practicing innovation in your life starts with identifying areas of need in your workplace or community.”

Skill 3 – Resilience

Resilience is the ability to bounce back from challenges and do it with optimism and positivity. All of us will face some sort of adversity in our jobs; we’re defined by the way we react to these experiences. An example of resilience at work is being open and receptive to criticism during annual reviews. Resilient employees take feedback as an opportunity for growth.  

Resilience takes time and diligence to master, but one place to start is to evaluate the way you react to uncomfortable situations whether in your life or even while enjoying movies, books or TV shows. See how negative situations make you feel. This will help you recognize these feelings and reactions, so that you can begin to adjust your response when confronted with setbacks in real life.

Put it into practice

Just like building muscle, you have to work on these skills to master them. The effort will pay off. Not only will these skills help you in the workplace, they also will help you succeed in life.
