Marine protected areas (MPAs) are designed to reduce threats to biodiversity and ecosystem functioning from anthropogenic activities. Assessment of MPAs effectiveness requires synchronous sampling of protected and non-protected areas at multiple spatial and temporal scales. We used an autonomous underwater vehicle to map benthic communities in replicate 'no-take' and 'general-use' (fishing allo...

Chronic undersampling of the marine environment, including both biological and physical components, has been and remains a major block to understanding how marine ecosystems function and how they respond to changes, whether natural or anthropogenic. Consequently, data-based models that accurately predict local variations in the abundance of plant and animal life in the sea are rare or do not ex...

Early detection of marine invasive species is key for mitigating and managing their impacts to ecosystems industries. Human divers are considered the gold standard tool detecting species, especially when dive teams familiar with local biodiversity. However, diver operations can be expensive dangerous, not always practical. Remote operated vehicles (ROVs) potentially overcome these limitations, ...
