Preliminary hydrographic surveys of some ponds in the Pelican Cays, Belize, Central America
Date of Original Version
Hydrographic and hydrologic surveys of three ponds in the Pelican Cays Group were carried out using hand-held sonar, pressure transducer tide loggers, and YSI temperature-salinity probes. These ponds characteristically have a circular pattern with steeply sloping sides. The pond depths range from 4.6 m in a small pond with a diameter of 100 m to 15.2 m in a large pond with a diameter of 840 m; in general, depth increases with increasing pond size. Depths ranged from 15.2 m for a distance of 100 m between cays to 28.7 m for a distance of 1,150 m. Pond salinities averaged 35.3 ppt with a range of 1.5 ppt, and temperatures averaged 31.4°C with surface temperatures about 1°C higher than bottom temperatures.
