Sedimentary proxy records from atoll lagoons and marine sediments
Co-PI Sam Bentley will develop a
paleohurricane proxy record from atoll lagoon and marine sediments in Belize by the identification of oceanic event layers.
Three areas are chosen for the study:
- A west-east transect from near the mouth of Mullins River to Southern Long Cay
- The Blue Hole of Lighthouse Reef
- Another W-E transect from the mouth of Monkey River to Zapotilla Cays.
Hurricane event layers in these settings are likely to be characterized by discrete beds
with sharp bases and upward-fining grain size. Vibra-cores and/or piston cores will be
collected at these locations in order to document the marine record of hurricanes along
the central and southern Belize margin.
