Widespread exposure of marine parks, whales, and whale sharks to shipping
Context: Shipping impacts are a major environmental concern that can affect the behaviour and health of marine mammals and fishes. The potential impacts of shipping within marine parks is rarely considered during the planning process.Aims: We assessed the areal disturbance footprint of shipping arou...
