Science comes with some wacky challenges. In the world of marine invasions, that might include sunburns from afternoons tying equipment to docks or worrying about how much seafood powder to feed a plate of invertebrates. But when someone dons a lab coat, they don’t shed their homelife, background, and personal responsibilities. At SERC-West, intern Jessenia Suarez got to know some of those unique challenges while working on her research project. But one of her biggest challenges was outside the lab.

Suarez is a senior marine biology major at San Francisco State University who found her passion for biology in her second year at community college. In summer 2019, she studied how a group of underwater creatures known as the fouling community responds to changes in water temperature. She found the work exciting and refreshing—but she admits that her biggest challenges were balancing the internship with a two-hour commute and finding childcare for her two-year-old daughter, Leia.

“I would spend about an hour and a half with her when I got home, and then it would be time to sleep,” she said. “Not only that, but I was still working my other job [as a CVS pharmacy technician]—very few hours, but it’s still time away from her. It was hard for me, and it was hard for her too.”

Besides caring for her daughter and working a second job, she also had to balance classes. Yet despite a heavier workload than the average intern, Suarez loved the internship experience, and she’s passionate about pursuing research after her degree.

“I had an idea that I liked doing research, but being in charge of my own project brought it to a whole new level, ” Suarez said. “I now know what to expect, and have a feeling that I can handle it.” Click to continue »

How Gassy is the Ground? SERC Intern Burps Baby Forests for Greenhouse Gases

Wednesday, October 2nd, 2019

Smithsonian Environmental Research Center intern Chaz Rhodes samples gases in the soil with equipment he helped design and install. It’s part of a new long-term study seeking to untangle what drives changes in the methane budget in forest soils.

by Alison Haigh

When it comes to forests, most people think of soil as a static ingredient in a recipe for growing trees. But talk to any forest ecologist, soil scientist, or biogeochemist, and you’ll get a radically different idea about dirt.

Soils are more like living, breathing ecosystems. Their most abundant residents aren’t plants or insects—they’re microbes. Microbes may be small, but they play a mighty role, especially in the carbon budget: They help make forests the largest carbon sink on the planet. Click to continue »

Move over, blue crabs. There’s a new predator in the education department. Sharks are making waves as the latest addition to field trips and engineering programs at the Smithsonian Environmental Research Center (SERC).

This spring, SERC added sharks as another station in its “Shoreline Connections” and “Exploring Nature” field trips. The education staff also created a day-long program that lets students think like scientists by planning a shark tagging expedition and designing their own shark tags.

“Most of the students and teachers and even parents don’t realize that there are sharks and rays in the Chesapeake Bay,” said Karen McDonald, director of SERC’s education center. “So this is new to them. And typically the organisms are vilified. So this is a chance for us to show their importance in the ecosystem.” Click to continue »

How Golden Star Tunicates Make Themselves at Home in an Alien Ecosystem

Friday, October 26th, 2018

By Philip Kiefer

Roughly half of the species living in the San Francisco Bay are newcomers, brought (often unintentionally) by humans. The Bay has been an international shipping hub for over a century, and it’s accumulated biological detritus from around the world. But not everything that’s brought here sticks: It’s something of a mystery why some species proliferate in an alien environment while others die off.

This summer, two interns at the Smithsonian Environmental Research Center’s West Coast branch (SERC-West), investigated how one invader cements itself in the environment during environmental chaos. Jenny Par and Kenyan Pappe looked at the golden star tunicate Botryllus schlosseri, a type of marine invertebrate that often lives around marinas.

Bio Blitz! Critters of the Eastern Shore

Tuesday, October 23rd, 2018

by Carmen Ritter, SERC Fish & Invertebrate Ecology Lab intern

Picture that tiny town that one friend always tells you they’re from, with the single post office and the neighbors that know every detail of your personal life. Now picture that, on the water, even smaller. Welcome to Wachapreague, Virginia.

Wachapreague sits on the Eastern Shore of Virginia and claims to be “The Flounder Capital of the World.” The locals are some of the friendliest people you could find, and nearly everyone in the area fishes. I wasn’t there for recreational purposes, though.

This summer, I visited the Virginia Institute of Marine Science Eastern Shore Lab (VIMS ESL) with about 20 scientists from around the country to conduct a bio blitz documenting the biodiversity of Chesapeake Bay. The blitz was organized by the Smithsonian Environmental Research Center and MarineGEO (the Marine Global Earth Observatory). While most scientists were from the Smithsonian and other research institutions surrounding the Chesapeake Bay, some flew in from Florida, Washington State or Puerto Rico. After gathering for a meeting on the first evening, we all prepared the lab space for samples and headed to bed. The blitz officially started first thing Monday morning.

War of the Periwinkles

Tuesday, October 9th, 2018

by Philip Kiefer

There’s a war of attrition playing out on the coastlines of the San Francisco Bay that is in a ponderous class of its own. A tiny snail, called a rough periwinkle (Littorina saxatilis), might be pushing its native counterpart, the checkered periwinkle (Littorina scutulata), from the beaches it once called home. But no one is quite sure why, or even how quickly it’s spreading.

Adrielle Cailipan, a recent graduate of San Francisco State University, is spending her summer internship in the world of periwinkles with the West Coast Lab of the Smithsonian Environmental Research Center (SERC). She’s working not only to document the spread of the rough periwinkle, but also to understand what makes the invader so successful.

How’s a Tree like a Cradle and a Straw? SERC Intern Studies Forest Methane Emissions

Monday, August 6th, 2018

By Philip Kiefer

Even healthy trees in the forest, like this tulip poplar, might be producing methane.

Until a decade ago, scientists believed forests were ravenous consumers of methane, a potent greenhouse gas. But we’re discovering that the story is more complicated. It turns out that while forest soils absorb methane, trees might actually release the gas. The problem is, no one is sure how much methane the trees are producing, or why they’re producing it at all.

“We’ve seen anything from 5 percent to 100 percent offset,” says Paul Brewer, a postdoctoral fellow at the Smithsonian Environmental Research Center (SERC).  That’s an enormous amount of uncertainty: The forest could be consuming as much methane as we once thought (almost all of it), or barely any at all.

SERC Intern Helps Pin Down Numbers

Maddie Peterson, an intern working for Brewer at the SERC Biogeochemistry Lab, is spending her summer trying to pin these numbers down.

She’s working to solve two questions. First, how much methane is an average tree releasing? And second, why is it doing so at all?

“The big question,” says Peterson, “is whether the trees are acting as straws” – siphoning methane up from deep in the earth – “or incubators” – cradling methane-producing bacteria in their trunks. Answering these questions will help scientists understand how methane moves in and out of the atmosphere, which is critical for predicting the course of climate change. Click to continue »

Wiring the Marsh: Intern Helps Build the Wetland of the Future

Wednesday, July 11th, 2018

By Philip Kiefer

Maya Bhalla-Ladd, who is beginning her second summer as an intern at the Smithsonian Environmental Research Center (SERC), didn’t think growing up that she would be a scientist. “In high school, I spent all my time on ballet,” she says. “I danced professionally. I lived on my own in New York.”

But when health problems forced her to turn away from ballet, she found herself drawn to the ocean. “I remember going to the aquarium as a kid and watching the rays,” she says. “The way they move is very naturally beautiful. So when I stopped being able to dance, I wanted to spend the rest of my life preserving that kind of natural beauty for other people to enjoy.”

Maya spent last summer at SERC’s Global Change Research Wetland (GCREW), investigating how climate change could affect photosynthesis in marsh plants. While there, she became fascinated with a tool used to measure photosynthesis in leaves. The tool seals a single leaf in a chamber and exposes it to light, causing the leaf to begin photosynthesis. It can then measure the precise gas composition of the chamber as the plant produces sugar. In effect, it can watch the plant breathe.

“I think that the instrumentation that enables science is so cool, and that we don’t spend enough time thinking about it,” Maya says. Click to continue »

“Orchids In Classrooms” Turns Sixth-Graders Into Citizen Scientists

Monday, July 9th, 2018

By Hannah-Marie Garcia, science writing intern

Think back to your early childhood science classes. Was there
ever a time you had to watch a plant grow? Your first natural sciences teacher may have used plant growth to explain basic concepts of plant biology. The process is a rewarding learning experience for students to observe their hard work pay off as those first few leaves sprout from the soil.

Now, imagine the work you did was part of a larger scientific project, with real-world applications. That is exactly what four sixth-grade classes are doing this year at Walker Mill Middle School. Located in a Capitol Heights neighborhood of the Prince George’s County school system, Walker Mill is one of seven schools in the Maryland area working with the Smithsonian Environmental Research Center (SERC) on a project called “Orchids in Classrooms.”

Meet Pepper, The Android Docent

Tuesday, July 3rd, 2018

by Kristen Minogue

Pepper close up, with blue eyes and tablet displaying options (Tell a Story, Do Something Fun and Need Information)Don’t panic. The new robot greeting visitors at the Reed Education Center isn’t about to stage a technological coup over the SERC campus. But it can pose for selfies, tell people about SERC programs and break out a dance move or two.

The robot goes by the name Pepper. Technically, Pepper has no gender, though most visitors—and a few staff—have taken to calling the robot “she” by default. The Smithsonian received a team of Pepper robots in February from SoftBank Robotics, to test out in their museums and other programs. Two Peppers went to the Smithsonian Environmental Research Center (SERC), where staff and students are programming them to interact with the public. Click to continue »
