“…Considerable effort has been invested in comparing the accuracy and agreement among different methods (e.g., Leujak and Ormond 2007;Facon et al 2016). The emerging consensus is to focus on the output variables from monitoring, rather than the methods: e.g., proportional cover for sessile taxa, abundance or density per unit area for mobile taxa and biomass, particularly for fishes.…”

Recognition of the threats to biodiversity and its importance to society has led to calls for globally coordinated sampling of trends in marine ecosystems. As a step to defining such efforts, we review current methods of collecting and managing marine biodiversity data. A fundamental component of marine biodiversity is knowing what, where, and when species are present. However, monitoring methods are invariably biased in what taxa, ecological guilds, and body sizes they collect.

“…In 1998 to 1999, benthic cover of patch reefs was determined using the line intercept transect method (cover recorded every 10 cm along 10 m transects, 4 replicates per patch). In 2008 to 2009, this method was modified to reduce necessary diving time through the use of digital photography (Dumas et al 2008), which has been shown to be comparable to the line intercept transect method for abundant substrate categories (Leujak & Ormond 2007). Images were taken 0.5 m above the benthos at 2 m intervals along 2 transects spanning the long and short axes of the patch.…”

Effective monitoring of populations and communities is a prerequisite for ecosystembased management of marine areas. However, monitoring programs often neglect important sources of error and thus can lead to biased estimates, spurious conclusions and false management actions. One such source of error is 'imperfect detectability', i.e. the inability of investigators to detect all individuals or all species in a surveyed area. Although there has been great effort to develop monitoring methods that account for imperfect detectability, the application of such methods in the marine environment is not as apparent as in other systems. Plot sampling is by far the most commonly applied method for biological monitoring in the marine environment, yet it largely ignores detectability issues. However, distance sampling, mark-recapture methods, repeated presence-absence surveys for occupancy estimation, and removal methods do estimate detection probabilities and provide unbiased estimates of state variables. We review these methods and the relevant tools for their application in studies on marine populations and communities, with the aim of assisting marine biologists and managers to understand the limitations and pitfalls associated with some approaches and to select the best available methods for their monitoring needs.
