C4 Services for the Coastal Zone
The overall output of this task component is the availability of several demonstrators for Earth-observation based services for users in the coastal zone.
Activity 1: Develop a global coastal zone information system: a global cyber-infrastructure that will provide access to available information on coastal zones and facilitate the collection of new information through crowd-sourcing and citizen-science
Activity 1.1: Develop the concept for a comprehensive information system that links a living knowledge base with a virtual stakeholder table and that can enable informed, participatory governance and decision making.
The outcome of this activity will be a community-vetted white paper describing a general concept for a future information system, with specific focus on governance and decision making in the coastal zone.
Activity 1.2: Implement the information system and populate the system for selected test-beds in North America, Africa, and potentially other locations.
As a result of this activity, a global cyberinfrastructure will provide a basis for communities in coastal zones to populate the system with their information and to use the system in their deliberations.
Activity 1.3: Utilize the information system for deliberations on a few selected topics such as planning for sea level rise, disaster risk reduction for extreme weather events, and identification of emerging public health risks to demonstrate the usability and value-added of the information system in participatory governance.
This activity will result in assessment reports that evaluate to what extent the information system enables informed participatory governance.
Activity 2: Implement a pilot project in an area-at-risk (e.g. Indonesian Archipelago-South China Sea domain) to demonstrate the added-value of ecosystem-based approaches for monitoring and managing the coastal zone. This will be coordinated with GOOS Regional Associations and global/regional networks (see Plan of the Panel for Integrated Coastal Observations)
Activity 3: Assess climate change impacts on island coasts for islands from the Caribbean to the Arctic using SAR data and other relevant data as a demonstrator for the use of space-based observations in the monitoring of climate change impacts. Data for this activity would be sought from CEOS members
Activity 3.1: Develop a description of the assessment detailing the time window to be considered, variables to be used to assess impacts, data needs and analysis approaches, and intended outcomes and reach a consensus between CEOS and a project team on data availability.
The result of this activity is a report providing a basis for the assessment.
Activity 3.2: Carry out the assessment defined in Activity 3.1.
The main outcome of this activity is not the assessment itself but rather a demonstration of how available remote sensing data can be used to assess climate impacts on a ocean-wide scale using slow changes in the coastal zone to base the assessment on.
Activity 4: Assess the observational requirements for decadal forecasts of coastal local sea-level variation and develop a demonstrator forecasting service
Activity 4.1: Develop and implement a system-of-systems model for local sea level (SoSLSL) that can be used to study the predictability of local sea level (LSL) at intraannual to multi-decadal time scales.
The outcome of this activity will be a open-source modeling framework for LSL that initially will be fully detailed for a few study cases, but can easily be set up for any coastal zone.
Activity 4.2: Use the SoSLSL to assess predictability of LSL depending on data availability. Identify Essential Sea Level Variables, particularly those that would serve the target to ensure early warnings in case of abrupt sea level rise, and define observation specifications for these variables.
This activity will have two main outcomes: (1) an assessment of the predictability of interannul to multidecadal LSL and (2) Essential Sea Level Variables (ESLVs) and specification for their observations.
Activity 4.3: Based on SoSLSL, implement a demonstrator that allows both, predictions of LSL within the range of predictability and queries for “What if” questions to determine LSL trajectories under assumed scenarios for climate change and climate change impacts.
The demonstrator will be available to decision makers and provide a novel way to assess the risk associated with LSL rise.
Activity 5: Assess user needs and observational requirements for coastal water quality (using the GEOSS User Requirements Registry); identify indicators and best practices for coastal water quality, and implement a monitoring service pilot for coastal water quality (with WA-01 and HE-01); disseminate information particularly to under-served communities (with IN-04)
Activity 5.1: Use the proposed Socio-Economic and Environmental Information Needs Knowledge Base (SEE IN KB) to capture water quality goals, targets, indicators and essential variables in deliberations with the relevant user communities.
The main outcome of this activity will be a set of Essential Water Quality Variables (EWQVs) and observation specification for these variables with particular focus on the information needs in the coastal zone.
Activity 5.2: Develop a demonstrator for a coastal water quality service based on observations of the EWQVs with the specific goal to make the information available to underrepresented communities.
The demonstrator will allow to assess data gaps and it will help to assess to what extent the information is of value to societal users, including underrepresented groups.
