Receiver deployments can be limited to the sites and depths where collaborators operate (e.g., sheltered sections at the back of reefs and islands; 5–9 m depth), which might not be optimal for detection range and might not be the best location where animals are most likely to swim past. | Receivers have the potential to be maintained indefinitely by collaborators, so the skeleton of the large-scale array remains in place, thereby reducing the impact that changes in receiver placement can have on large-scale movement studies. |
Animals may not be tagged near a receiver, or in a region with only one receiver. Risk of collecting very little data for some species if not enough individuals move to a region with more receivers or swims past single receivers. | Ability to tag at many more locations within the enhanced Queensland array skeleton (e.g., multiple locations to address connectivity and stock structure questions). |
Single receiver deployments may not detect the same number of individuals as installations with more receivers. | Faster and cheaper to service, and gaps between local arrays can be more easily filled, providing much larger spatial coverage and resolution. Advantageous for studying large-scale movements of multiple species over time. |
