Subtidal Methods Comparison

A number of scuba-based programs are attempting to capture the status and trends of kelp forests and associated biodiversity. Each program was initiated with a different purpose with distinct methods.  Trade-offs in terms of the accuracy of the data, number of team members required, and time underwater include spatial coverage, species included, needed resources etc. A subgroup of WG2 participants is working on a paper to summarize and compare these diverse methods. In addition, the paper will (1) provide decision-making tools illustrated through case studies and technical considerations, (2) provide social-ecological context by linking measured variables to derived products and societal impacts (through a Sankey diagram), and (3) explore different methods' potential to support biodiversity indicators (BIP, EVs).
