5 unlikely ocean friendships - Woods Hole Oceanographic Institution
2024年5月24日 · In 1977, scientists discovered hydrothermal vents. These seafloor hot springs release mineral-rich water that attracts an abundance of life, including shrimp, crabs, and six-foot-tall tubeworms.
A new tagging method for fragile marine species
Bioadhesive Interface for Marine Sensors (BIMS) can be attached to marine animals in less than 20 seconds. Traditional tagging methods could take up to ten minutes, causing stress to animals, making these a better alternative. Here, Dr. Pedro Alfono places a tagged squid back in the water in the Azores after using a traditional suture tag.
Marine Mammal Acoustics - Woods Hole Oceanographic Institution
They must rely on many technologies to track and record marine mammals. Their tools include radio tags, acoustic tags (with transponders), satellite tags, hydrophones, and vocalights (developed by Tyack). Scientists can get an even more detailed look at marine mammal sounds using visual representations of sound called spectrograms.
