Because of their proximity to the ocean, Californians get to enjoy locally-sourced oysters, mussels, abalone and clams.
As the size and number of acoustic datasets increase, accurately and quickly matching the bioacoustics signals to their corresponding sources becomes more challenging and important. This is especially difficult in noisy, natural acoustic environments. At the 182nd ASA Meeting, Elizabeth Ferguson, from Ocean Science Analytics, will describe how DeepSqueak, a deep learning tool, can classify underwater acoustic signals. It uses deep neural network image recognition and classification methods to determine the important features within spectrograms, then match those features to specific sources.
The bottom of the ocean is full of mysteries but scientists have recently uncovered one of its best-kept secrets. For 25 years, drug hunters have been searching for the source of a natural chemical that had shown promise in initial studies for treating cancer. Now, researchers at University of Utah Health report that easy-to-find soft corals make the elusive compound.
If a human comes down with a rash, they might go to the doctor and come away with some ointment to put on it. Indo-Pacific bottlenose dolphins get skin conditions, too, but they come about their medication by queuing up nose-to-tail to rub themselves against corals.

For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different moon phases: bright light during full moon and only starlight under new moon, researchers have a better understanding of why this circling behavior happens and why it is most commonly observed in leatherbacks.
Most bottom-dwelling marine invertebrate animals, such as sponges, corals, worms and oysters, produce tiny larvae that swim in the ocean prior to attaching to the seafloor and transforming into juveniles.
