The best topographic data, including regular contours;
Evidence for subsidence/uplift, including the methods used to determine;
Bathymetric charts and maps, particularly for shallow water areas (<10-m depth);
Coastal geomorphology (i.e., hard unerodible cliffs, erodible cliffs, beaches, wetlands, etc.) to select appropriate
impact models;
Wave data, or wave hindcasts to define the wave climate;
Tide gauge data to define tidal characteristics and flood elevations (Note that 50 years of data is required to
confidently extract long-term sea-level trends (Douglas, 1991; Nicholls and Leatherman, 1996) so this is
unlikely);
Estimates of flood return periods, from tide gauges and/or hindcasts;
Historical storm and flood damage from major storms, including physical changes and socio-economic costs;
Present status of coastal ecosystems, particularly coral reefs and wetlands. How much degradation and destruction
has occurred, and what is the prognosis for the future without climate change?
Scientific research on ecosystem response to climate change, particularly examples in the Caribbean.
Present coastal problems, including (1) beach erosion, (2) cliff erosion, (3) coastal flooding by storm surge, (4)
coastal flooding by run-off, (5) saltwater intrusion, (6) others? Information should be as quantitative as possible
and put as much emphasis on the long-term rather than the short-term;
Any response to these problems, including both hard and soft engineering (seawalls, nourishment, etc.) and
institutional changes (building setbacks, coastal zone management programs, etc.);
Human influence on sediment availability at the coast. List areas where dams have been built on rivers, coastal
erosion has been stopped, and littoral drift has been impeded;
Coastal land use and historical changes in coastal land use;
Plans for major future infrastructure development such as ports, airports, etc. which will be close to present sea
levels;
Development of coastal tourism, if appropriate and plans for future development;
Coastal population distribution and historical changes in coastal population distribution;
Forecasts of coastal population distribution.
