Drivers of Increased Orca (Orcinus orca) Sightings Along the South African Coastline
This research explores the ecological, environmental, or anthropogenic factors potentially contributing to the observed increase in orca sightings in South African waters. It seeks to determine whether these trends reflect shifts in prey distribution, changes in oceanographic conditions, or variations in reporting and monitoring efforts.
In plain words
More orcas seem to be turning up along South Africa's coast, but is that because their food has moved, the sea has changed, or simply because more people are watching and reporting them? Knowing which would help protect sea life.
Primary research question
What factors are associated with the reported increase in orca (Orcinus orca) occurrences along the South African coast?
Knowledge gap
What remains worth asking
There is a lack of clarity regarding whether the perceived increase in orca presence represents a genuine shift in population distribution, a change in migratory behavior, or an artifact of increased public and scientific observation.
Potential contribution
Why it may matter
Understanding these trends is essential for marine conservation, the management of coastal ecosystems, and the protection of apex predators within South African marine protected areas.

Quality and audit
76/100 quality
Safeguard-based audit was not recorded under the prior standard.
- The research question is well-defined and addresses a clear, observable phenomenon.
- The scope is appropriately bounded by geography and species.
- The proposal is neutral and avoids speculative conclusions regarding the causes of the sightings.
This older record can be checked against the current standard on request. It changes only if every academic gate and independent safeguard passes.
