Healthy oceans need healthy soundscapes, say marine scientists
A global team of researchers has found overwhelming evidence that marine fauna and their ecosystems are negatively impacted by noise, which disrupts their behavior, physiology, and reproduction, and can even cause mortality.
New analysis highlights importance of groundwater discharge into oceans
An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, but a new study finds groundwater discharge plays a more significant role than had been thought.

Alaska’s salmon are getting smaller, affecting people and ecosystems
The size of salmon returning to rivers in Alaska has declined dramatically over the past 60 years because they are spending fewer years at sea, according to a new study. Salmon are critically important to both people and ecosystems in Alaska. Smaller salmon provide less food for people who depend on them, less value for commercial fishers, and less fertilizer for terrestrial ecosystems.

Marine scientist Adina Paytan to receive A.G. Huntsman Medal from Royal Society of Canada
UCSC Newscenter — The 2019 A.G. Huntsman Medal will be awarded to Paytan “in recognition of her discoveries in the paleoceanographic history of important elements used to recreate the geochemical history of the planet, and of outstanding contributions to understanding the biogeochemical links between global earth-ocean-atmosphere nutrient controls on carbon productivity and paleoclimate.”
