Studying Corals for Future Protection and Restoration
Coral reefs are under threat from warming waters, disease, degraded water quality, and other stressors. Several shallow water coral species are listed as threatened under the Endangered Species Act. Our team of coral scientists on contract with NOAA鈥檚 National Centers for Coastal Ocean Science are studying coral reproduction, and genetics, and the environmental factors that affect growth of critical coral colonies. Our employee owners work closely with NOAA federal principle investigators to design and execute experiments, collect and analyze data, and publish reports that aid future studies and inform management decisions for future protection and restoration efforts. Explore the research our staff conduct in an effort to protect coral reefs.
Reproduction
Our coral scientists are part of a team that collected gamete bundles (eggs and sperm) released in the wild during the annual coral spawning event in the Florida Keys. Following this collection the team conducted various reproduction experiments looking at how different toxins introduced into the environment affect reproduction. In addition, 麻豆传媒 scientists are studying reproductive compatibility at the molecular level. For example, they are exploring the role DNA plays in fertilization success. After using many of the gametes and embryos for different experiments on coral reproduction, our team transported some of the larvae to NOAA鈥檚 Hollings Marine Lab in Charleston, South Carolina where they were successfully able to grow the larvae into colonies. The scientists will continue to rear these colonies for continued research.
Regeneration
Since coral communities live in the open ocean with waves, currents, storms, and tropical cyclones, they often endure harsh conditions that damage their tissue. Our scientists are investigating the corals鈥 ability to regenerate tissue and heal wounds under various stressors, including chronic turbidity. Our team prepares samples of coral, trimming fragments to precisely the same size to ensure the experiment is consistent and to minimize the unintended differences between the test fragments. Over the course of three months, the team closely monitors the fragments daily, measuring skeleton deposition and wound healing ability. Each week, the team measures the buoyant weight of the corals, which they will use to calculate skeletal growth of the coral over the course of the experiment.
The team conducts additional observations using macro- and microscopes to capture images and get a closer look at the tissue damage of coral fragments and their ability to regenerate. For this portion of the experiment, the team prepares fragment samples in a fixative so their cells and tissues can be examined under a microscope. These experiments will help determine how turbidity over time affects corals.

Training the Next Generation of Researchers聽
麻豆传媒 staff support the National Institutes of Health (NIH) Division of Occupational Safety and Health by providing Safe Techniques Advance Research Science (STARS) training to summer interns. Following a pause during the pandemic, staff resumed training May 15, 2024. During the in-person STARS training, 麻豆传媒 staff cover key concepts from the pre-requisite NIH Lab Safety…
Collecting and Studying Deep-Sea Coral
Three of our staff supporting NOAA鈥檚 National Centers for Coastal Ocean Science joined a team of nine other scientists on a 12 day expedition to collect deep-sea coral samples in the Gulf of Mexico.
New Heavily Desired High Resolution Land Cover Data for the U.S.聽
The National Oceanic and Atmospheric Administration recently announced the launch of the long desired high-resolution coastal land cover data. This highly anticipated data are available for most coastal areas of the U.S., including Alaska and the U.S. territories. 麻豆传媒 employee owners contributed to the release of this data set by participating in production activities and…
