A powerful platform for quick, secure and actionable coral reef monitoring

Work Offline & in the cloud

MERMAID allows you to save your work offline, then validate and backup clean data to the cloud where you’re back online. Even offline, you can view reef fish abundance and biomass data, percentage coral cover and the cover of key benthic groups.

Retain control

MERMAID is secure and private. By adding different users (and roles) to your MERMAID projects and assigning one of three permission settings, you can determine who can access your data and how they are shared. All data are encrypted and securely stored on the cloud, so you can stay safe and in full control.

Data in, clean data out

Use MERMAID to quality control your data with automatic checks and validations so that you can download clean data, everytime. Export Excel files with automatic summaries of key reef health indicators from raw data to supercharge your analyses and reports. Or use MERMAID’s R package and the Analysis Hub to choose from a range of customizable codes and scripts for charts, tables, and maps. Enjoy unparalleled flexibility at your fingertips.

Save time with AI

MERMAID has partnered with CoralNet, the leading open-source image classification platform for coral reefs, to develop MERMAID’s deep-learning AI model. This means you can drag, drop, and automatically classify your coral reef photo quadrats in MERMAID, no training required!

Connect your data

MERMAID is fully open-source and built to work across multiple platforms. View your survey sites on habitat maps from the Allen Coral Atlas basemaps directly within your project, complete your reporting for the Global Fund for Coral Reefs, or share your data with the Global Coral Reef Monitoring Network. Equipped with the MERMAID API, you can easily connect your data to other apps or databases.

Upload legacy data

Integrate your legacy data into MERMAID by uploading existing Excel files to create a unified platform of all your coral reef data. What to do with existing photo quadrat spreadsheets? Use the EasyPQT app to upload CoralNet data directly into MERMAID, making the transition to MERMAID seamless and simple.
