Kid Superheroes: Saving the Planet, One Environmental Issue at a Time!

Superheroes are all around us, but they aren’t wearing capes or running at super speed. Instead, they’re passionate kids, using their voices and demanding to be heard, especially when it comes to sparking environmental change. This Clean Beaches Week (July 1-7), we’re sharing examples of how kids are making a difference in their communities (and beyond) as evidenced through research by Dr. Nancy Foster Scholar, Jenna Hartley.

Listening and Learning in Cordell Bank National Marine Sanctuary

Imagine life in the deep, dark ocean where you cannot easily see or smell, but need to find food and companionship, and navigate from place to place while avoiding predators. Your eyes and nose would not be much help; instead, you would need to rely on sound to make sense of your environment.

Graduate Scholarship Program Celebrates 20 Years of Enhancing Women and Minorities in NOAA Sciences

Twenty years ago, NOAA created the Dr. Nancy Foster Scholarship Program in honor of the late Dr. Nancy Foster. This scholarship provides support for independent graduate-level studies in oceanography, marine biology, or maritime archaeology disciplines, including all science, engineering, social science, and resource management of ocean and coastal areas. Based on language within the National Marine Sanctuaries Act, an emphasis was put on strongly encouraging women and members of minority groups to apply for the scholarship. To date, scholarship selections have been based on academic excellence, letters of recommendation, research and career goals, and financial need.

Some Like It Hot: Foster Scholar Elise Keister Investigates Why Some Coral Reefs Can’t Withstand Warmer Ocean Temperatures While Others Can

Is 80ºF hot? If you live in the southeast, 80ºF can be a pitstop to even warmer days. But in the temperate Pacific Northwest, that same temperature can be scorching. Like people, different coral reefs can have dramatically different tolerances to warmer ocean temperatures. In Florida Keys National Marine Sanctuary, researchers have noticed that when ocean temperature rises—even by 1 or 2 degrees—some reefs struggle while others are resilient. Why are certain reefs in the same region doing better than others?

A Balancing Act: Foster Scholar Nury Molina Studies How Fish Keep Coral Reefs Healthy

A coral reef is part of a delicate balancing act. When stony corals dominate the ocean floor, they form vibrant reefs that are home to marine life. Besides being hotspots teeming with life, reefs can protect shorelines from storms by absorbing coastal swell and storm surge. But corals are also constantly competing with algae for space. If algae out-compete the corals, once-productive coral reefs can become covered by algae, forming deserted areas called algal barrens. When this happens, the natural reef barrier breaks down, leaving our coastlines vulnerable to flooding and property damage. When coral reefs are damaged and overrun by algae, how can the scale be tipped back towards healthy coral reefs?

Whales and ships: Foster Scholar Vanessa ZoBell studies whether slower ships improve whale communication in Channel Islands National Marine Sanctuary

The ocean teems with intriguing sounds. Beneath the crashing waves, a sea bass bleats. Snapping shrimp provide a delicate, rhythmic background for charismatic humpback whale calls that boom through the water. Humans also make sounds that add to the mix: for example, as cargo ships deliver necessary goods between ports, they add their own low pitch track. All these sounds coexist: how do we ensure they are a symphony and not a cacophony?

Foster Scholar Erin Arneson Examines Coral Resilience to Ocean Acidification

Diving at Gray’s Reef National Marine Sanctuary, one thing is obvious: it’s a hidden treasure. A patchwork of Oculina corals alternates with colonized rock to form the sanctuary’s hard bottom reef. Multitudes of marine organisms — from small zooplankton and jellies to larger predators like fish and sharks — inhabit the reef.

Kids can: Foster Scholar Jenna Hartley empowers students and teachers to tackle marine debris in their communities

Kids these days show us they can do anything. From organizing rallies to encouraging people and businesses to make sustainable choices, Generation Z doesn’t back down from environmental challenges. So it’s only fitting that Jenna Hartley is working with Generation Z students and their teachers to see how young people can make waves teaching their communities about marine debris.

The shark took my fish: Foster Scholar Grace Casselberry investigates depredation in Florida Keys National Marine Sanctuary

It’s a bright, sunny day in Florida Keys National Marine Sanctuary — perfect for a fishing trip. As you sit on your boat, enjoying the slight rocking from the waves, you feel a tug on your line. You wrestle with an Atlantic tarpon, a large, shiny silver fish that many anglers flock to this national marine sanctuary to catch. Just as you’re about to bring the fish out of the water, a hammerhead shark swoops in and eats your prize. As you sit there mourning the loss of your tarpon, a little spark of optimism grows when you realize there is a scientist working on this exact issue. She is Dr. Nancy Foster Scholar Grace Casselberry, and she wants to prevent hammerhead sharks from eating your catch.

Tree rings and deep-sea corals: Coral skeletons teach Foster Scholar Carina Fish about the past ocean

Deep-sea corals have some things in common with trees. As their branches grow, corals document the minute details of ocean chemistry in ring patterns like those in tree trunks. And like certain trees, some coral species can live for hundreds or even thousands of years, preserving their recording of past conditions. Dr. Nancy Foster Scholar Carina Fish uncovers the records kept by deep-sea corals in Cordell Bank National Marine Sanctuary for her Ph.D. at University of California, Davis.

The case of the missing oxygen: Foster Scholar Kate Hewett studies hypoxia in national marine sanctuaries

Not every marine scientist has the same origin story. Some are instantly enthralled by the ocean and its many inhabitants at a ripe young age. For others, a lightbulb goes off while sitting in an undergraduate class. Dr. Nancy Foster Scholar Kate Hewett grew up on the islands of Micronesia, but did not consider a career in marine sciences until graduate school. While working as an environmental engineer in Boston, Massachusetts, she decided to go back to school to develop a deeper understanding of the environmental problems she encountered at work. In her classes, the complicated physics associated with coastal zones pulled at Hewett’s engineering heartstrings.

Voyage of the seal: Foster Scholar Sarah Kienle identifies differences in elephant seal feeding patterns

It was almost an ordinary day in the field for Dr. Nancy Foster Scholar Sarah Kienle - except for the Jeff Corwin show camera crew. She was helping the crew with a routine procedure on an adult female northern elephant seal in Año Nuevo State Reserve, using a pulley attached to a sling and a tripod system to lift the seal so the team could weigh her.

Where do they go? Dr. Nancy Foster Scholar Richard Coleman tracks fish populations in Papahānaumokuākea

Many Native Hawaiian fishers will tell you the same thing: there are not plenty of fish in the sea. In their childhood, they would throw nets into the ocean and catch numerous large fish. Today, when they bring their children to their traditional fishing grounds, their nets often come up empty. Where did the fish go?

Reaching out and diving deep: Foster Scholar Alexandra Avila shares what lies beneath the waves

You may not know it when you dive into a sanctuary, but there are baby fish everywhere. Newly-hatched fish, or larvae, are microscopic and at the whim of ocean currents. It's possible that via these currents, larvae populations throughout different parts of the ocean could be connected. But are these currents strong enough to connect populations of fish hundreds of miles away - like those in Oregon and Olympic Coast National Marine Sanctuary in Washington? Dr. Nancy Foster Scholar and Oregon State University Ph.D. candidate Alexandra Avila wants to find out.

Coral CSI: Foster Scholar Andrea Kealoha analyzes water chemistry for clues about invertebrate mortality events

Swimming through hazy, green waters in the Gulf of Mexico in 2016, divers knew something was off at Flower Garden Banks National Marine Sanctuary. That’s when they noticed the vast quantities of dead marine organisms around them, and curious white mats covering the corals. One area of this pristine sanctuary was no longer teeming with life. When marine organisms die suddenly and no one knows why, that’s when you need a dedicated group of scientists for a special episode of Coral CSI.

Whale hello there: Foster Scholar Angela Szesciorka tracks whale behavior near ships

Dr. Nancy Foster Scholar Angela Szesciorka's research sounds simple enough. For her Ph.D. at Scripps Institution of Oceanography at the University of California, San Diego, she studies the impact of shipping on blue, humpback, and fin whales throughout the four national marine sanctuaries off of California – Channel Islands, Monterey Bay, Greater Farallones, and Cordell Bank. She figures out where the ships go, then figures out where the whales go, and sees how they intersect.

The coral doctor: Foster Scholar Michael Fox gives corals the best chance he can

When faced with a devastating flu season, we humans look to public health specialists. When exposed to changes in their environment, corals can get sick too. When corals are not healthy at Hawaiian Islands Humpback National Marine Sanctuary and Pacific Remote Islands National Marine Monument, Michael Fox is on the case.

Grace, size, and mystery: Foster Scholar Joshua Stewart’s work in Flower Garden Banks National Marine Sanctuary supports manta conservation

This is how Dr. Nancy Foster Scholar Joshua Stewart describes his first time seeing the subject of his dissertation work, a manta ray. Diving near a shipwreck in the Dominican Republic, he was caught off guard when a manta ray shot up towards the surface. Stewart turned his video camera to the creature, and it mocked him with a belly flash and swam off. Stewart checked his camera. It wasn’t recording, and no one believed his story. But that experience kicked off his interest in this playful gentle giant, and inspired his research in Flower Garden Banks National Marine Sanctuary.

From watching whales to searching for dolphins: Foster Scholar Tammy Silva's scientific career revolves around Stellwagen Bank

It was the first time anyone had tried listening for dolphins in Massachusetts Bay. Tammy Silva scrolled through sound recordings and spectrograms for months, seeing nothing. Then, she found it. The right kind of squiggly lines and corresponding whistles. She heard dolphins.

What's in your vomit? Foster Scholar Anna Robuck explores contaminants in Stellwagen Bank National Marine Sanctuary

Bird vomit is important for Anna Robuck. After a lot of practice as a wildlife rehabilitator, Robuck is now able to deftly flush the stomach contents from a bird. The bird beats a hasty retreat away unscathed, and Robuck is left with a treasure trove of diet information.

Call of the wild: Foster Scholar Samara Haver studies sound across sanctuaries

The sounds of the ocean are an odd combination of haunting and soothing. From the crash of waves on the beach to the echo of whale songs, it's tempting to believe putting a shell up to your ear will allow you to access the underwater soundscape whenever you need an escape. Unfortunately it doesn’t work that way. But Samara Haver has the next best thing: underwater sound recordings of national marine sanctuaries and national parks.

Community through science: Foster Scholar Nissa Kreidler sheds light on deep-sea habitats

Dive under the waves, and you’ll find vast communities of marine organisms. From busy kelp forests to vibrant coral reefs, marine communities rely on each other for food and shelter. Communities and support networks are equally important for graduate students, albeit more difficult to establish at first. The Dr. Nancy Foster Scholarship Program provides just that: a tight-knit community of peers and mentors. It's this sense of togetherness that brought Nissa Kreidler to the Dr. Nancy Foster Scholarship Program.
