See MoreThe ocean is a busy place. Whether we are shipping materials, catching fish or generating clean energy, we can use the ocean while also protecting and restoring nature. But first, we need to understand what marine life, such as fish and birds, uses the same parts of the ocean that we use and what places are important to these animals’ health and survival. The Nature Conservancy’s Marine Mapping Tool makes it easy to review publicly available information about Atlantic Ocean habitats and species, so decisions we make can be supported by the best science and data available.
There are two versions of the tool; one for the Northeast Atlantic (from Maine to North Carolina), and one for the Southeast (from North Carolina to Florida). Both versions tell us about the plant and animal species that may be present in the ocean, but each version is different because the needs for each region are different.
The Northeast Marine Mapping Tool has been updated to better answer questions that tool users have about critical habitats that species rely on and the vulnerability of certain species and habitats.
These new features are important because the most effective conservation actions require not only understanding what species are present in a location and how abundant they are, but also what habitats and other features are important to them, including back on the coast. The data is organized in a way that allows conservation decisions to be made by looking at the marine ecosystem more holistically. The hope is that consistent use of the tool will support actions that improve outcomes for nature.
New Features to the Northeast Marine Mapping Tool
The Northeast Marine Mapping Tool was developed by TNC in collaboration with potential users to answer questions that tool users have about identifying critical habitats that species rely on, and the vulnerability of certain species and habitats. The new features allow users to make more informed conservation decisions and improve outcomes for marine plants and animals.
Benefits of the tool:
It is free to use and available to anyone with internet access
It provides trusted information that has been peer reviewed by scientists
It takes decades of complex data and makes them understandable for all parties and stakeholders.
“Developing the tool was a collaborative process with the people and scientists who use the data to make decisions. We wanted to provide enough information so they can use the tool to make decisions, enough transparency so they can trust the data they see, and also enough context to the data to help users understand what the numbers mean. We’re excited to debut these updates to support mitigation and other conservation decisions," said TNC’s Marta Ribera, designer of the Marine Mapping Tool.

How Coastal Restoration Helps Marine Life
Sometimes the best way to help marine ecosystems is to restore coastal habitats. Read about how TNC is working on coastlines to help the fish, mammals and birds of the ocean thrive.
Who should use the Marine Mapping Tool?
Anyone can use the tool, but it is intended to support people who choose the most effective conservation and mitigation actions for marine plants and animals. That includes:
