The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
Sea lions, otters and birds were some of the many wildlife species that were hit hard by the 1989 Exxon Valdez oil spill in Alaska. Oil spills like these expose the wildlife to new contaminants and can be fatal.

A closer look at how ice cover changed through the months offers some important insights into the role of climate change and why every year isn’t a record.

Some of the climate changes will be irreversible for millennia. But some can be slowed and even stopped if countries quickly reduce their greenhouse gas emissions, including from burning fossil fuels.
Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.

Belugas use sound to communicate, navigate the dark marine environment and find food. But climate change is opening up Arctic waters to more sound, and could affect the health and survival of belugas.
