Description

Bottom Disturbance refers to the disturbance of the sea bottom or seabed as a result of human activities. This can be physical disturbance or chemical disturbance, for instance, leakages.

MSP Challenge

The Bottom Disturbance layer is calculated on a month-by-month basis considering the existing (and planned) human activities in the sea basin. The contribution from each human activity to the total Bottom Disturbance in the sea region is defined from 0 (no impact) to 1 (full impact) by expert knowledge.

Bottom disturbance is subsequently a pressure on the ecosystem. This means that this data layer is fed into the ecosystem simulation (EwE), and the ecosystem simulation will provide the users with the expected response from the species in the ecossystem.

Return to pressures.
