The challenge of designing a device to learn what marine mammals do on dives is the stuff of dreams for an electronics engineer.
One group of bacteria—the cyanobacteria—has completely transformed Earth’s environment through their long history. Three billion years ago, ancestors of cyanobacteria infused Earth’s ancient atmosphere with the byproduct of their photosynthesis—oxygen—changing the chemistry of the planet and setting the stage for entirely new oxygen-breathing life forms to evolve. Without the cyanobacteria, the life we see around us, including humans, simply wouldn’t be here.
For decades, the Nassau grouper (Epinephelus striatus) was one of the most sought-after fish species in the Caribbean and Gulf of Mexico, from the Bahamas to Central America. These large, delicious fish live among coral reefs and have a breeding behavior that makes them especially vulnerable. They come together in aggregations of thousands to spawn at specific times and places, making them easy to catch—and to overfish.
The words “coral reefs” conjure up images of a tropical paradise: shallow, warm, aquamarine waters, bright sunlight, white coral sand, and colorful, darting fish. But corals also live deep in the sea, in regions where the sun doesn’t penetrate and water temperatures remain just above freezing.
Bioluminescence is ubiquitous in the oceans, and especially prevalent in coastal regions where nutrients are abundant and life thrives. Yet scientists have little basic understanding of how bioluminescence is influenced by water temperatures, depths, seasons, geographic locations, even different times of day.
News Releases
The National Institute of Environmental Health Sciences (NIEHS) and National Science Foundation (NSF) have announced that the Woods Hole Oceanographic Institution (WHOI) will receive funding to continue operating the Woods Hole Center for Oceans and Human Health (WHCOHH).
Newly developed bioadhesive sensors (BIMS) are effective and less invasive than traditional tagging. Scientists can attach them with a thin layer of dried-hydrogel in less than 20 seconds.
Researchers from WHOI studied the microbes in coral reef water by examining eight reefs in the U.S. Virgin Islands over a period of seven years, which included periods of hurricane and coral disease disturbance.
Researchers at WHOI demonstrated that replaying healthy reef sounds could potentially be used to encourage coral larvae to recolonize damaged or degraded reefs.
High resolution satellite imagery and field-based validation surveys have provided the first multi-year time series documenting emperor penguin populations.

MIT-WHOI Joint Program student Jaida Elcock celebrates Shark Week and shark awareness in this Q&A
At the northernmost year-round research station in the world, scientists brave frigid temperatures and perpetual night to solve an ocean mystery. The team is trying to figure out how some of the tiniest animals survive at a time of year when their main food source is not available.
