Soil heat exchange in Puerto Cuatreros tidal flats, Argentina
Some interaction processes at the sediment-water and sediment-atmosphere interfaces were analyzed for each season of the year using mass aerodynamic formulas. Data were collected from Puerto Cuatreros tidal flats (Bahía Blanca estuary, Argentina) during an entire year (2000). The soil temp...

Data were collected from Puerto Cuatreros tidal flats (Bahía Blanca estuary, Argentina) during an entire year (2000). The soil temperature was measured every 10 min by a thermistor chain at three levels below the sediment surface (–0.05, –0.15 and –0.25 m). Water and air temperatures, solar radiation and meteorological data were registered simultaneously, resulting in annual means of 14.07ºC (soil at –0.15 m), 13.69ºC (air) and 14.51ºC (water). Atmospheric and tidal conditions regulated the mudflat's thermal behavior. The soil temperature vertical profiles showed a diurnal and semidiurnal cycle due to the influence of these factors. The diurnal thermal amplitude at –0.05 m reached 14.6ºC on 20 February 2000, but only 2.8ºC on 1 July 2000. Most fluctuations of sediment temperatures were observed in the first 15 cm, with vertical gradients of 0.82ºC cm–1 during summer. In order to obtain the soil heat capacity, the granulometric composition of a sediment column was analyzed. Soil heat fluxes during a typical summer and winter day were compared. A net heat gain in the soil was observed during the summer day (+840.6 kJ m–2) and an inverse situation was found in winter, with a diurnal heat exchange of –768.6 kJ m–2.Se analizaron procesos de interacción sedimento-agua y sedimento-atmósfera para cada estación del año mediante formulas aerodinámicas de masa. Los datos fueron recolectados en la llanura intermareal de Puerto Cuatreros (estuario de Bahía Blanca) durante un período anual (2000). La temperatura del suelo se midió cada 10 min empleando una cadena de termistores localizados a tres niveles de profundidad: –0.05, –0.15 y –0.25 m. Simultáneamente, se registraron las temperaturas del agua y del aire, la radiación solar y datos meteorológicos. Los valores medios anuales fueron 14.07ºC, 13.69ºC y 14.51ºC para sedimento a –0.15 m, aire y agua, respectivamente. La radiación solar y las mareas regularon el comportamiento térmico de la planicie de marea. Debido a la influencia de estos factores los perfiles verticales de temperatura del sedimento mostraron un ciclo diurno y semidiurno. La amplitud térmica diurna a –0.05 m alcanzó los 14.6ºC el 20 de febrero, mientras que durante el 1º de julio se observaron sólo 2.8ºC de amplitud. Las mayores fluctuaciones en la temperatura del sedimento se registraron en los primeros 15 cm, desarrollándose gradientes verticales que alcanzaron los 0.82ºC cm–1 durante el verano. A fin de obtener la capacidad calorífica del suelo en estudio se analizó la granulometría de una columna de sedimentos. Se comparó el flujo de calor en el suelo durante un día típico de verano y uno de invierno evidenciándose una ganancia neta de calor durante la jornada estival (+840.6 kJ m–2) y una situación inversa en el invierno (–768.6 kJ m–2).Iniversidad Autónoma de Baja California2003-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/19710.7773/cm.v29i42.197Ciencias Marinas; Vol. 29 No. 4B (2003); 595-602Ciencias Marinas; Vol. 29 Núm. 4B (2003); 595-6022395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/197/166info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/1972024-08-22T17:01:29Z |

Some interaction processes at the sediment-water and sediment-atmosphere interfaces were analyzed for each season of the year using mass aerodynamic formulas. Data were collected from Puerto Cuatreros tidal flats (Bahía Blanca estuary, Argentina) during an entire year (2000). The soil temperature was measured every 10 min by a thermistor chain at three levels below the sediment surface (–0.05, –0.15 and –0.25 m). Water and air temperatures, solar radiation and meteorological data were registered simultaneously, resulting in annual means of 14.07ºC (soil at –0.15 m), 13.69ºC (air) and 14.51ºC (water). Atmospheric and tidal conditions regulated the mudflat's thermal behavior. The soil temperature vertical profiles showed a diurnal and semidiurnal cycle due to the influence of these factors. The diurnal thermal amplitude at –0.05 m reached 14.6ºC on 20 February 2000, but only 2.8ºC on 1 July 2000.
