In this study we analyzed sediment cores to investigate the Holocene history of the Tobacco Range mangrove complex and to see how these thick peat accumulations relate to other reports of Holocene Belizean peat deposits. We were particularly interested in how radiocarbon dated samples from this and previous studies provide a better understanding of the late Holocene sea-level curve for the Belize area. In addition, we collected subsurface data in an attempt to explain the unique fracturing and slumping of submerged peat off the northwest coast of the Tobacco Range island complex. METHODS During March 1987, seven continuous sediment cores were collected using a vibracorer with aluminum pipes, each of which was 9 m long with a diameter of cm and fitted with a core catcher. (). Six of these cores were collected along a transect (oriented southeast to northwest) that bisects the northeastern and largest island of the Tobacco Range mangrove complex (), five of which were collected from the west coast ~ one on the island, one from the shallow-water unfractured peat surface, and three from deeper areas of slumped peat (). o Vibracores # Soil-sampling probe cores Meters.
