“The saline wetlands are a really unique but vulnerable environment, and many people aren’t aware of them.” A novel archaea isolated in Nebraska is named after the state by @rockNmicrobe and her team at the University of Nebraska-Lincoln. Read more here🔗 https://t.co/myt7xlzS2M

Every day is Earth Day at USGS! 🌍

If every drop of water on, in, and above the Earth was gathered into a single ball, it would be surprisingly small compared to the planet. While 71% of Earth’s surface is covered by water, that represents only a thin layer.

So how much water is there on Earth?
💧 96.5% is saline water in oceans
💧 2.5% is found as freshwater
💧 30% of the freshwater is stored in the ground
💧 69% of that freshwater is stored in glaciers and ice caps
💧 about 1% is accessible in lakes and rivers

Earth's water supply is finite and constantly moving through the water cycle. Understanding why the tiny sphere of water shown is critical helps put Earth Day into perspective. While water is abundant, easily accessible freshwater is a scarce, precious resource that is the lifeblood of our planet.

EarthCache Spotlight: Nebraska Sandhills, United States

Spanning nearly 20,000 square miles, the Nebraska Sandhills form the largest sand dune complex in the Western Hemisphere. Shaped by winds at the end of the last Ice Age, dunes up to 400 feet high were later stabilized by grasslands. Beneath lies the Ogallala Aquifer, where sandy soils recharge one of the world’s largest groundwater reservoirs, creating thousands of lakes and wetlands between the dunes.

📍 Location: Nebraska, United States
📊 Difficulty: 2/5 | Terrain: 1/5

Tiny Wires, Big Power

Did you know some bacteria can make electricity? ⚡

Geobacter microbes form protein “nanowires” to move electrons outside their cells, turning methane into power. Clean energy might just be microscopic!
