Oceanus Magazine
Welcome to the online version of Oceanus, the magazine that explores Earth’s last frontier. Oceanus delivers news and commentary on the meaning and value of ocean research, engineering, and education at Woods Hole Oceanographic Institution.
The challenge of designing a device to learn what marine mammals do on dives is the stuff of dreams for an electronics engineer.
For the first time in history, we can accompany a whale on its dive, hear what it hears, and observe its normal, natural, previously hidden behavior in the depths. Working closely together, scientists and engineers have created an innovative new device—the digital acoustic recording tag, or D-tag. It attaches to a living whale and records nearly everything that happens on its dives, without disturbing the animal.
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.
