Benthic line transect (LIT)

This transect records observations of benthic cover from a benthic line intercept transect.

Each transect requires a transect number and the surveyed length (m).

Enter the benthic observations from the transect 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' or 'Return' key to select a name.

Growth forms can be selected from the dropdown list or predicted by typing. The total length and 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’ keys to move across to the attribute, growth form, and length columns. At the end of the row, press 'Enter' to create a blank row and add a new benthic attribute observation. If the same attribute is observed but with a different length, press the ‘Tab’ key at the end of the row to duplicate the benthic attribute in the next row.
