The single biggest motivation of the Ocean Health Index project is to use science to inform marine management. And not just any science, the best available science, data, methods, and tools. Open data science is helping us get there, with transparency, reproducibility, collaboration, and communication at its core.Read More...
What is the Ocean Health Index?
The Ocean Health Index ('OHI') is a scientific framework used to measure how healthy oceans are. Understanding the state of our oceans is a first step towards ensuring they can continue providing humans benefits now and in the future.Learn more Download data Visit our overview website oceanhealthindex.org
Where have OHI assessments been done?
We've led global OHI assessments of 220 coastal nations and territories every year since 2012, and also lead OHI assessments at smaller scales.
Additionally, we share code and provide training and support for independent groups interested in leading their own OHI assessments. These are called independent OHI assessments, or 'OHI+ assessments'.

Open data science for marine science and management
The OHI is transforming the way marine science streamlines with coastal management by leveraging practices and tools from open science and data science. We work openly online and have shared our story in publications and blogs. We teach these practices and tools to groups leading OHI+ assessments.Better science in less time
How do I get started?
The Ocean Health Index (OHI) has been changing conversations about ocean management. The OHI framework helps focus the discussions about benefits that the ocean provides to people in a particular area; it helps keep management targets in mind when considering which information could be included in an OHI assessment.Read More...
