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.



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.
