Welcome to MERMAID Documentation page. Here we will walk you through the steps of using MERMAID App and explain in details its features and functionalities.

MERMAID is an open-source application that collects and manages real-time data on coral reef health, developed in partnership between the WCS, WWF, and Sparkgeo.

With MERMAID, scientists input their observations straight into the platform using the Web app. MERMAID does the job of tagging and sorting data, avoiding duplicates, standardizing scientific names and summarizing critical indicators.

We save you time so you can save coral reefs!

MERMAID joins you in the field with its offline capabilities, but it stands apart from Excel or other databases, like Access, because it requires virtually zero post-entry data clean up! 

Users can select reef fish and coral names from a standard list of taxa with only a few keystrokes; MERMAID will autocomplete the rest. Selecting names means saving time typing in species names or cleaning up typos of misspelled species names.

MERMAID also allows you to calculate reef fish biomass while you type, or see your total coral cover as soon as you have finished entering a transect. When you have finished collecting data, it can be exported to standard field reports (Excel) and can soon be used to create graphs or other reports.

    2. Enter site information
    3. Enter management regime
    4. Include benthic attributes and fish species
    5. Complete and save the transect
  3. Review and submit 
    1. Review and submit data
    2. Address any errors and warnings
  4. Export and analyze data
    1. Export to .XLSX for further analysis
