Resumen
Se hizo un estudio detallado de la fijación de carbón radiactivo en dos lagunas costeras tropicales de la costa del Pacífico mexicano, con el propósito de estimar la tasa diurna de productividad primaria (∑p), Los datos así obtenidos fueron utilizados para evaluar y adaptar modelos de cálculo para la integración de las curvas de p/I (Productividad/Intensidad luminosa), Las integrales comúnmente empleadas en estudios oceanográficos requieren datos precisos de p en la región de baja iluminación y no contemplan los efectos de la fotoinhibición y, por lo tanto, no son aplicables al caso actual. Se desarrolló un modelo que solamente requiere conocimiento de la altura y posición del máximo sub superficial de p y que permite el cálculo preciso de ∑p.
