Shhhh, the whales are resting (Tue, 16 Jun 2020)
Researchers recommend new guidelines for noise levels from whale-watching boats after having carried out experiments with humpback whales. They exposed the whales to different levels of boat-engine noises while observing the current guidelines for whale-watching -- keeping 100 meters distance, for instance -- while monitoring the whales' behavior closely with a drone camera. The researchers concluded that the noise level from a boat's engine should stay below 150 decibels.

Good night? Satellite data uncovers dolphins on the move at nighttime (Tue, 02 Jun 2020)
More than 1,000 bottlenose dolphins live in Florida's Indian River Lagoon year-round. Although extensively studied, what they do at nighttime is still a mystery. Using satellite telemetry, scientists provide the first documentation that these dolphins have a larger range that encompasses more habitats than previously thought. They regularly leave the brackish waters of the estuarine system and, not only travel into the ocean, but swim substantial distances -- up to 20 kilometers -- up freshwater rivers, creeks, and canals.
