Benthic Photo Quadrat

This transect records the result of the photo identification from benthic photo quadrat observations.

Each transect requires a transect number, depth (m), surveyed transect length (m), the start of the quadrat, the quadrat size (m2), the number of quadrats, and the number of points per quadrat.

Enter the photo identification results from the photo quadrat observations at the bottom of the form.

MERMAID will predict the benthic attributes after you type the first three letters. this ensures all spelling is correct and consistent. Select the benthic attribute by using the 'up' or 'down' arrow keys or entering more letters so that there is only one choice, and press the 'Enter'/'Return' or 'Tab' key to select a name.

Growth forms can be selected from the dropdown list or predicted by typing. The percent cover of each benthic attribute will automatically be calculated at the bottom of the rows.

Indo-Pacific benthic attributes are included in this version of MERMAID. They can be found in the "Reference" icon at the header of any page. New benthic attributes can be proposed to the MERMAID science team for approval and addition.


Use the 'Tab' key to move across the attribute, growth form, and number of point columns. At the end of the row, press 'Enter' to create a blank row and add a new benthic attribute observation.
