ICAN is a project of UNESCO IOC´s IODE Programme, and ICAN members seek to play a leadership role in forging international collaborations of value to the participating nations, thereby optimizing regional governance in coastal zone management and marine spatial planning.


We live on a blue planet, with oceans and seas covering more than 70 per cent of the Earth’s surface. Oceans feed us, regulate our climate, and generate most of the oxygen we breathe. Some 37 per cent of the world's population lives within 100 km of the coast. (UNEP)


CWAs are "...collections of digital maps and datasets with supplementary tables, illustrations, & information that systematically illustrate the coast, oftentimes with cartographic & decision support tools, all of which are accessible via the Internet."  O'Dea et al., 2007


Membership in ICAN is open to all interested parties who agree to the mission & objectives of ICAN, including those with an operational coastal web atlas, as well as those hoping to design and build a coastal web atlas in the future.

NOAA’s Gulf of Mexico Data Atlas joins ICAN

ICAN is very pleased to welcome it's latest member, the Gulf of Mexico Data Atlas ( From the atlas summary: "As plans to restore the Gulf of Mexico after recent disasters have progressed, federal and state agencies have turned to NOAA for data and information about all aspects of the Gulf of Mexico. One of the most requested resources for that data and information has been the "Gulf of Mexico Coastal and Ocean Zones Strategic Assessment Data Atlas" published by NOAA's National Ocean Service in 1985 as a large hardcopy tabletop book. The new Gulf of Mexico Data Atlas updates and expands that publication in an online, digital format."

North Carolina COHAZ Decision Portal Conveys Critical Data and Useful Mapping Products

The coast of North Carolina is at risk to a diversity of hazards (e.g., storm surge, sea-level rise), and these hazards potentially can have major consequences (financial and otherwise) for people who live, work, and recreate in impacted areas.  There has been much research conducted on coastal hazards affecting North Carolina and their ramification, but information is scattered and often hard to track down.  Also, it is typically not in a form suitable for public consumption.  To improve on these issues, a team of researchers from the departments of Geological Sciences and Geography at East Carolina University (ECU) has worked with others at ECU and around the state to develop a web-based information site on coastal hazards and related research; it is called the North Carolina COastal HAZards (NC COHAZ) Decision Portal.  At the site (, a variety of information on coastal hazards in the state (particularly the northeastern portion) has been coalesced.

Figure 2: An example NCCOHAZ tool available to the public. This Google Maps API-based tool is designed to allow anyone to view the risk of inlet-opening potential along the Outer Banks. These GIS data also were provided to FEMA prior to the landfall of Hurricane Irene, and as predicted two of the four very-high-risk areas experienced island breaches.

Visitors to the web portal are welcomed by a colorful banner at the top of the web page (Figure 1).  On the main entrance page, “news bytes” are regularly updated using an integrated blog; these short pieces communicate interesting hazard-related stories or information and usually feature a photograph, map or video.  The “Maps and Visualizations” page provides links to a variety of tools and products on topics such as current hazards, shoreline erosion and inlet-opening potential (Figure 2).  Several user-friendly mapping tools have been created to allow researchers, managers and the public to explore maps of immediate or potential hazards (e.g., sites of flooding, strong winds, large waves).  The approach used for presentation and validity of some of the tools can be argued (e.g., erosion projections).  Nevertheless, the creators believe it is better to have this information out and available where it can be considered, rather than hidden in hard-to-find journals or difficult-to-obtain reports. 

Please take some time to visit the NC COHAZ Decision Portal.  The developers have a variety of ideas on how to expand the site, such as plans for a more formal marine atlas.  But, if you have any suggestions or thoughts on information contained on the site or data you would like to see added, etc., do not hesitate to contact J.P. Walsh, Esta dirección de correo electrónico está siendo protegida contra los robots de spam. Necesita tener JavaScript habilitado para poder verlo., (252) 328-5431. Feedback of any kind is appreciated.  Hopefully, this site will improve communication and information on coastal data exchange around the state and beyond.  Ultimately, the goal of NC COHAZ is to help mitigate the effects of coastal hazards on the citizens of North Carolina, and this can only be accomplished through better sharing of knowledge, data and ideas.
