Abstract

The Long Island Sound and its watershed encompass an area of about 17,000 square miles and include the Connecticut, Housatonic, and Thames Rivers, which all drain to the sound. Dozens of organizations from government agencies, nonprofits, and Tribal Nations have developed projects and monitoring programs to analyze and protect the water resources of the watershed and sound. The abundance of data and lack of an existing searchable index require a centralized metadata repository to allow users to find water resources data more efficiently. The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency and the Long Island Sound Study, has created an interactive map application to visualize and search for metadata information across organizations working to monitor and protect the Long Island Sound.

Plain Language Summary

The Long Island Sound watershed is home to nearly 9 million people in parts of Connecticut, Massachusetts, New Hampshire, New York, Rhode Island, Vermont, and Canada. Government agencies, nonprofits, and Tribal Nations have overseen numerous projects to monitor and protect the water resources of this watershed and the sound. Although there is an abundance of data, there is no easy way to search them or a central place to manage this information. To help, the U.S. Geological Survey, the U.S. Environmental Protection Agency, and the Long Island Sound Study have created an interactive map to help users find and understand data about the water resources of the Long Island Sound and its watershed.
