Title in Portuguese
Variação diurna do fluxo de CO2 na interface ar-mar do Oceano Atlântico Equatorial
Keywords in Portuguese
Fluxo de CO2
oceano Atlântico equatorial
pressão parcial do CO2
velocidade de transferência do CO2
Abstract in Portuguese
O ciclo diurno do fluxo de CO2 no oceano Atlântico equatorial para o mês de agosto é estimado utilizando um algoritmo de transferência de gases. O algoritmo é baseado na teoria de similaridade de Monin-Obukhov para fluxos turbulentos na interface ar-mar e na física da transferência de CO2 na camada molecular oceânica. O ciclo diurno do fluxo de CO2, obtido na região, caracteriza o oceano Atlântico equatorial, durante o período, como fonte de CO2 para a atmosfera e seus valores estão entre 0,71 e 0,85 mol CO2 m^-2 ano^-1.
Title in English
Diurnal variation of the CO2 flux at the Air-Sea Interface of the Equatorial Atlantic Ocean
Keywords in English
CO2 Flux
CO2 transfer velocity
Equatorial Atlantic Ocean
Partial Pressure of the CO2
Abstract in English
The diurnal cycle of CO2 is estimated for the month of August on the Atlantic Ocean using a gas transfer algorithm. The algorithm is based on the Monin-Obukhov similarity theory for turbulent transfer at the air-sea interface and the physics of the CO2 transfer at the oceanic molecular layer.
