Chesapeake Water Watch

The Chesapeake Bay, our nation's largest estuary and home to Maryland’s famous blue crabs, faces threats from runoff, pesticides, population growth, overharvesting, and climate change. Monitoring the quality of the bay’s water helps guide actions to protect and preserve this ecosystem. The Chesapeake Water Watch project asks you to help monitor the bay using a free smartphone app or by collecting water samples. Project researchers will use your measurements to help "train" NASA satellites to fill in the complete water quality picture of this large and complex estuary.

Chesapeake Water Watch logo. This rectangular block displays the project name in black capital letters, with a few subtle adornments. The "A" in water is highlighted in a blue teardrop of water, underneath which we see blue waves. The "A" in watch is a satellite. At the bottom we see the logos of the City College of New York, the Smithsonian Environmental Research Center, and the NASA Partner logo.
A woman wearing a sun hat, short sleeve shirt, and shorts kneels on a dock in the bay. The cell phone in her hands is aimed at a grey piece of paper on her clipboard, which is the reference image that calibrates water color. The far shore is covered in trees.

Two women in short sleeved blue shirts stand looking at the water, their backs to the photographer. In front of them is a water, its surface lightly ruffled by wind, and the green trees of the far shore.
Project volunteer Sharon Hensley and project coordinator Shelby Brown check their study location on the Rhode River to ensure that there's no debris, foam, or other material on the surface of the water that would influence the HydroColor app readings.
