NEW - TERRESTRIAL ECOLOGICAL AND CULTURAL HERITAGE SITE MAPPING
From July 2011 – June 2012, Alison DeGraff (of Middlebury College) Compton Foundation Fellow, together with her mentor Kim Baldwin (of CERMES, UWI) used a participatory approach to map and collect terrestrial heritage data on important historical, cultural, and ecological sites of the Grenadine Islands. This information fills the identified data gaps in the Grenadines MarSIS and will serve to strengthen the current application of the Grenadine Islands as a transboundary UNESCO marine mixed (cultural/ecological) World Heritage Site. This designation can offer the two countries international status, inspire ecotourism initiatives, and provide further legitimacy for endeavours to protect the Grenadine coastal and marine ecosystem.
The heritage dataset includes information on:

COASTAL MARINE HABITAT AND RESOURCE MAPPING
Marine habitat was mapped during a four week research cruise aboard a 47’ catamaran provided by The Moorings in 2009. This research cruise was a collaborative effort between multiple organisations (academia, private sector and government) resulting in a first of its kind habitat and resource map of the Grenadine Islands and Grenada Bank. The research crew consists of two Grenadines fishers: Kester Douglas and Albert Hanson (also a marine park ranger from the Tobago Cays Marine Park); a local captain, George Steele; two fisheries biologists from CERMES, Renata Goodridge and Kim Baldwin; and two deck-hands Fabian and Amy Peters.
Critical marine habitats such as reefs, seagrass, and mangroves as well as areas important for fishing were mapped during the cruise.
A combination of remote sensing and ground-truthing was used to map the shallower coastal water areas; and a live-action drop camera was deployed off of the catamaran in deeper waters to map marine habitat up to 250 ft. in depth. Depth data was also collected (every 30 seconds the catamaran was in motion) using a Garmin GPS sonar to develop a 3D seafloor map of the Grenada Bank.
In addition, fishing knowledge was also collected to identify areas important for the various fisheries, types of gear used and to the model quality of the Grenada Bank fishing grounds. Information collected was merged using GIS software and a first of its kind 3D map of the Grenada Bank seafloor was created.
DEVELOPING A USEFUL MARINE HABITAT MAP
STEP 1: Marine Habitat Classification Scheme
To model habitat of the deep waters (up to the 60 m in depth) of the Grenada Bank, GIS was used to overlay a 1 km2 grid over the Grenada Bank and in which we surveyed 10% of the grid cells.
At each site, a SeaViewer underwater video camera was used to record and view the type of marine habitat as well as assess the suitability of the fishing ground.
Local fishermen and captain were hired as part of the research team.
Seafloor depth data was also collected during the cruise using a sonar (Garmin GPS 540s) and with the use of GIS we developed a first-time (or baseline) 3D marine habitat map of the Grenada Bank.
