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.

Paws up for science: Foster Scholar Jessica Hale tracks sea otter habits in Olympic Coast National Marine Sanctuary

The northern sea otter is the furry ambassador of Olympic Coast National Marine Sanctuary. With their knack for naps and holding hands as they float, their cute faces are pervasive both along the coast and on social media. But it wasn't always so this way.

The Biology Bus: A Q & A with Dr. Nancy Foster Scholar Alumna Dr. Nyssa Silbiger

Here's a conundrum: you have one summer to study intertidal organisms in 12 sites up and down the West Coast. How do you do it?

Foster Scholar Lindsay Marks Takes on Invasive Species

The kelp forests of Channel Islands National Marine Sanctuary provide shelter and food for hundreds of species of animals and plants, from abalone to sea lions. So how does an invasive seaweed impact this important ecosystem?
