Entering a transect

When you’re ready to enter new data for a project, click “Add Sample Unit” at the top right of the Collect page and select a sample unit.

There are currently five types of sample units available on MERMAID: reef fish belt transects, coral point intercept (PIT) transects, coral line intercept (LIT) transects, habitat complexity transects, and bleaching quadrat collections. These transects are similar to methods described in the Coral Reef Monitoring Protocol for Assessing Marine Protected Areas (Ahmadia et. al 2013) (Appendix 2).

After selecting a transect type, you must fill in all required fields, marked with a red asterisk. Sites and Management Regimes that you added before or after creating your project will appear in the dropdown, and you can edit an existing site with the pencil icon or enter a new site with the “+”.

Optional transect information includes reef slope, visibility, current, relative depth, tide, and any notes.

Each transect requires at least one ‘observer’, defined as the person or people who collected the transect observations. This is a required field, and you can choose from a dropdown list of users associated with your project. To remove an observer, click the red ‘x’.

Once all required fields are completed, you can save the transect.

When online, you can validate and submit the transect. Offline, only the ‘Save’ button will appear.

Deleting a Transect

If you wish to delete a transect, click the "delete this record" button at the bottom of any transect page. This will permanently remove the record and its observations from MERMAID, so be sure that you want to remove it.
