Ocean swells are constantly occurring across the Earth’s oceans. These swells interact with the ocean crust below, creating continuous ocean noise that travels all over the Earth, including through our active volcanoes here in Hawaii. Because ocean noise signals are always being generated, scientists can use these seismic sources to identify small changes occurring in the Earth’s crust over time.

Strategically expanding the National Park System could help build a rich biodiverse conservation system across the country.

Climate-change is being blamed for the loss of roughly 10 trillion gallons of water — an amount roughly equal to the capacity of Lake Mead — from the Colorado River Basin from 2000 to 2021.
