Caracterización de dos lagunas costeras del Pacífico tropical mexicano en relación con el contenido de carbono y la captura y emisión de CH4 Y CO2

The study of greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), has a global relevance and their accumulation in the atmosphere by emissions from human activities affect the Earth’s radiative balance. Coastal lagoons are considered important reservoirs of carbon, but it is unclear whether they contribute as sources or sinks. This paper presents an estimate of CO2 and CH4 water-air fluxes in Chautengo and Tres Palos lagoons in Guerrero, Mexico, during the dry season and also examines the role of those water reservoirs in the carbon emission-sequestration, according to environmental conditions. In Chautengo the average capture of CH4 was 8.7 mg/m 2 /day and emission
