Representing the function and sensitivity of coastal interfaces in Earth system models.

Area of Science:

• Environmental Science
• Coastal Ecology
• Earth System Science

Background:

• Coastal ecosystems are critical interfaces between land and ocean, facilitating material transformation, storage, and transport.
• Hydrological and hydrodynamic processes (river discharge, tides, waves, storms) drive energy and matter exchange in these dynamic zones.
• Current global models inadequately represent coastal processes and their feedbacks, limiting accurate predictions of environmental change.

Purpose of the Study:

• To evaluate the current state of coastal monitoring networks and regional models.
• To identify existing challenges in observing and modeling coastal processes.
• To propose a framework for developing global models that better incorporate coastal dynamics.

Main Methods:

• Review of existing coastal monitoring networks.
• Assessment of current regional coastal models.
• Analysis of challenges in coastal process representation.

Main Results:

• Significant gaps exist in current coastal monitoring and modeling capabilities.
• Existing models often fail to capture the complexity of coastal material and energy exchange.
• The integration of diverse data sources and advanced modeling techniques is necessary.

Conclusions:

• Improved representation of coastal processes in global models is crucial for accurate climate and environmental change predictions.
• Enhanced coastal monitoring networks are essential for validating and refining these models.
• A coordinated global effort is needed to advance coastal Earth system science.
