1. The sea is much larger than the land surface, subject to different legal regimes and with natural processes, species and ecosystems that cross between them.
2. Water is less transparent than air, making remote sensing of the oceans and the seabed more difficult.
3. The sea is more three-dimensional, adding to the complexity of mapping, planning and managing processes and activities within it.
4. It is fluid and interconnected, allowing for easier transport of pollutants and alien species.
5. Marine species travel further, making the management and tracking of resources more difficult.
6. Marine species can shift location rapidly, so measures to protect them in one place may be less effective as time goes by.
7. Nutrients and pollutants can cycle in the ocean for decades, making it harder to assess the long-term impact of…
