Medición continúa de flujo de CO2 en suelo en una parcela de bosque tropical en Isla Barro Colorado, Canal de Panamá.

Abstract

This paper describes the field work that has been done for 21 months and the preliminary results of continuously measurements of soil CO2 flux on a 1 ha plot in the artificial island of Barro Colorado, using a close long term chamber method with an infrared gas analyzer. The period mean for soil CO2 flux registered was 2.92 µmol/m²s and can be explained by the influence of the soil humidity. Finally, these measurements need to be done continuously and for a long period of time in order to evaluate the spatial and seasonal variability.
