Quantification Approaches from Marine Imagery 2024

Abstract

Monitoring of benthic habitats requires the ability to be able to survey ecosystems using methods which are not only cost effective, but also efficient, appropriate for the habitat type and the purpose of the survey. The scope of the present report was to summarise various commonly employed quantification techniques used to analyse still imagery, gaining knowledge and guidance from the literature, and presented in a format which can be used as guidance when planning survey work. A literature review was undertaken systemically using the PRISMA framework using a keyword search to identify literature. From the relevant literature identified during the review, information regarding quantification approaches, advantages/disadvantages, etc. were extracted and terms standardised to allow comparability.

Five main quantification categories were summarised, ranging from qualitative to fully quantitative methods: Presence/Absence, SACFOR, Point count, Frequency of Occurrence and abundance (count, biomass and seabed cover).
