Many people are familiar with—or have at least heard of—the Mariana Trench. Located in the western Pacific Ocean, this crescent-shaped feature on Earth’s crust is the deepest part of the world’s ocean, reaching a maximum depth of 36,070 feet (10,994 meters) in an area known as “Challenger Deep.”

Over two days in late August, a team of nearly 30 scientists, engineers, technicians and project managers met at BIOS to plan their approach for the next phase of the three-year COral Reef Airborne Laboratory (CORAL) project.

Sitting in a math lecture at the University of Cambridge in England last winter, Scott Li was focused on the course and completing his term work during his third year in the Department of Applied Mathematics and Theoretical Physics. That is, until a researcher in the university’s Department of Earth Sciences walked in at the end of the lecture to encourage students to apply for the Cawthorn Cambridge Internship at BIOS.

Understanding our planet and how it functions, as well as the impacts that human activities have on it, requires frequent and extended forays into the field to yield valuable data and observations. The COral Reef Airborne Laboratory (CORAL) investigation is a prime example. The three-year mission, funded by the NASA Earth Venture Suborbital-2 program, is conducting airborne remote sensing campaigns, along with in-water field validation activities, across four coral reef regions in the western and central Pacific Ocean.

When scientists study coral reefs, they are often interested in figuring out key components of reef health; specifically, primary production—or photosynthesis—and calcification, the rate at which new reef growth occurs. For decades this has meant time and labor-intensive fieldwork, with scientists documenting global reef condition and linking what they see underwater with lab-based experiments and measurements.

NASA’s Earth Venture Suborbital-2 Program has awarded BIOS scientist Dr. Eric Hochberg a grant to initiate the COral Reef Airborne Laboratory (CORAL). The three-year project will use an instrument mounted within the belly of an airplane to survey reefs around the world.  By using airborne data to calculate the amount of coral present on a reef, and to assess the processes underpinning coral reef growth or decline, CORAL provides a new and unprecedented perspective on coral reef ecosystems.

BIOS reef ecologist Eric Hochberg, principal investigator of the COral Reef Airborne Laboratory (CORAL) mission, provided a lunchtime seminar to scientists and staff at NASA headquarters in Washington, D.C. on August 15 to outline the mission’s goals, science, and status.

Similar to forests on land, the most important source of energy for tropical shallow water coral reefs is light. Photosynthetic algae, called zooxanthellae, live within the tissues of reef-building corals and provide them with oxygen and the products of photosynthesis, including glucose and amino acids. The corals, in turn, use these products as the energy source for building calcium carbonate skeletons and growing more living tissue. Other ecologically important reef organisms, such as macroalgae and turf algae, depend on light for growth and reproduction as well, making light the driving force behind the growth and overall productivity of coral reef ecosystems.

For many jobs in the science, technology, engineering, and mathematics (STEM) fields, hands-on experience in research is a valuable asset, if not a requirement. This presents a unique challenge to undergraduate students who often lack the time, networking resources, and track record to obtain even entry-level positions that would provide such experience. Since 1987 the National Science Foundation (NSF) has been supporting thousands of undergraduate researchers each year through its Research Experiences for Undergraduates (REU) program.
