The Caribbean island of Carriacou is notable for its recurrent drought, paucity of large, native land animals, and well-developed bank and barrier reef system. These environmental conditions presented challenges and opportunities to the Amerindians, Europeans, and enslaved Africans who settled here through time. While available evidence suggests human presence has altered island ecology through agriculture, deforestation, erosion, species introductions, and extinction, overall human ecodynamics remain poorly understood. In 2018, the Carriacou Ecodynamics Archaeology Project (CEAP) initiated a field program investigating long-term human-environment interaction to reconstruct Carriacou's landscape history. The CEAP seeks to develop high-resolution records for anthropogenic habitat modification and change in biotic communities from initial Amerindian settlement (ca. AD 400) through the colonial period (1740s–1974) up to the present. Pilot investigations comprising pedestrian survey, test pitting, site mapping, and geophysical survey targeted the coastal archaeological site Sabazan, where ca. 1,600 years of pre- and post-contact settlement are recorded. Here, we present the results of this first field season, demonstrating the potential of geophysical survey approaches in the Caribbean and the need for renewed, focused attention to Carriacou's archaeological resources which are being rapidly lost due to coastal erosion.
