Contenido de carbono orgánico y características texturales de los sedimentos del sistema costero lagunar Chantuto-Panzacola, Chiapas

Seasonal and spatial distribution of surface sediments from the Chantuto-Panzacola coastal lagoon system were analyzed, including organic carbon (O.C.) content, during the years 1997 to 2003. Surface sediments were taken from 10 sites by means of a small van Veen grab sampler (3L) and sediment composition (sand, silt and clay components) was obtained by pipette analysis. There were differences in the sediment’s O.C. inbetween dry and wet seasons, with higher levels corresponding to the latter and showing that O.C. contributions to the system come from autochthonous and allochthonous sources through fluvial drainage. O.C. levels throughout the lagoons were highest in stations 4
