“…No significant difference was detected for salinity for all seasons while for temperature significant difference between the three tidal periods was detected only in winter ( Table 1). The nitrite NO 2 -fluctuated between seasons (ANOVA, F = 13.48, n = 36, P < 0.05) and the concentration values ranged between 0.08 µmol/L in winter to 1.08 µmol/l in spring. Significant difference was detected between the three tidal periods and SNK post-hoc test revealed that those concentration values were high during the T2 and T3 periods for all seasons (Table 1).…”

“…Significant difference was recorded between the tidal periods on the winter, spring and autumn periods and the highest concentration values were observed on the slack and ebb period. Silicate Si(OH) 2 concentrations fluctuated between seasons (ANOVA, F = 4.43, n = 36, P < 0.05). The silicate concentrations were high in spring and autumn and low in winter and summer.…”

“…They are generally adapted to low light levels and are, therefore, able to survive in the turbid conditions [1]. Phytoplankton distribution patterns reflect the interplay between phytoplankton growth rates, commonly regulated by light, inorganic nutrients, temperature, light availability, nutrient inputs, residence times and turbulence [2,3]. These controlling factors depend on the spatial and temporal variability of physical parameters such as depth, flow velocity, and turbidity [4,5].…”

“…In this coastal zone the climate is dry and arid with northerly winds prevailing throughout the year. However, to the south of southern parallel 28°N south-westernly and westernly winds are common in summer and autumn (Zaitsev et al, 2010), which modifies the coastal hydrodynamic (Durazo et al, 2005;Durazo et al, 2011). The largest, deepest and southernmost lagoon of the Baja-California Peninsula, Bahia-Magdalena, is located in this area Due to its wealth of marine resources, the ecological aspects of the aforementioned lagoon were studied extensively, as summarized in the review of Funes-Rodríguez et al (2007).…”

Abstract. The coastal lagoon of Bahía-Magdalena, located on the west coast of the Peninsula of Baja-California, is a subtropical ecosystem with an arid climate and very little freshwater input. During the 2005-2011 period the thermohaline properties varied between cold and warm halfyearly periods. They were influenced by the Transitional Water mass transported by the South California Current from February to July and by the Subtropical Surface Water from August to January. The nutrient concentrations increased (viz up to 16 µM of nitrate) from March to June, when the upwelling index was the highest. Similarly, the inter-annual variation of chlorophyll-a showed a six-monthly pattern with the highest average monthly concentrations being found in June (5 mg·m -3 in situ or 8 mg·m -3 based on satellite information) and the lowest in DecemberJanuary. A spatial zoning was also observed in the lagoon with a shallow inner zone that is warmer and richer in chlorophyll-a than the deeper closed mouth area. In the Bahía-Magdalena lagoon a spatial-temporal division into two zones and two seasons was repeated year after year with only minor differences. During the first semester in the outer zone, years 2006 and 2007 were colder and nutrient rich while 2010 was warmer, according to the upwelling conditions in the Southern California Region. Hence, among the coastal lagoons that present a prevailing marine influence, the coastal system of Bahía-Magdalena corresponds to an unusual type of subtropical coastal lagoon where the nutrient input is mainly due to upwelling phenomena.Keywords: inter-annual, intra-annual, biogeochemistry, California Current, chocked lagoon, Bahía-Magdalena, Pacific coast, Mexico. -INTRODUCTIONContinental shelf waters represent 8% of the Earth's oceanic surface but it is where nearly 25% of the primary sea production occurs (Walsh, 1989) and where a variety of types of coastal systems, which determine the exchange between land and sea, are found. In these systems, coastal lagoons, making up 13% of the coastal areas worldwide, are predominant (Kjerve 1994). Coastal lagoons are inland water bodies, usually oriented parallel to the coast, separated from the sea by a barrier and connected to the ocean by one or more restricted inlets (Kjerfve and Magill 1989). In the subtropical climate region bordering, as delimited by Perillo et al. (1999), the Tropics of Cancer and Capricorn (23.5° latitude) and the temperate region (40° latitude), coastal lagoons are subject to a wide climatic diversity ranging from monsoons to desert-like conditions. In all of these climate types the availability of nutrients restricts biological richness (Salomons et al., 2005). Despite this fact, subtropical coastal lagoons have not been studied extensively from a biogeochemical viewpoint, rather it is the ecological aspects that have undergone a more indepth examination (Kjerfve, 1994).The wide variety of subtropical coastal lagoons have been classified according to the type of entrance channel into choked, restricted or leaky lago...

“…These concentrations are higher than in areas were advection of subsurface waters occurs. Off the west coast of Baja California, upwelled waters tend to have DIC concentrations of ~2150 mol kg -1 and maximum pCO 2 values of 800 atm (Ribas-Ribas et al 2011), considering that the water typically comes from ~80 m (Linacre et al 2010). Values of ~2200 mol kg -1 and pCO 2 > 900 atm have been reported for upwelled water off Oregon, where the winds are more intense (10 m s -1 ) and the water is transported from ~200 m (Feely et al 2008).…”

ABSTRACT. In the Midriff Islands region (MIR) of the Gulf of California (Mexico), tidal mixing plays a very important role in the distribution of chemical properties. Although the temporal variability of the water masses is linked to the ocean dynamics of this region, its importance has not been considered. This work estimates the effect of water mass dynamics on the spatial distribution and seasonal variation of dissolved inorganic carbon (DIC) in the region, with special emphasis on the Ballenas Channel, during winter 2002, spring 2003, and summer 2004. Gulf of California Water (GCW) was found throughout the area in the first 100 m. Below, Subtropical Subsurface Water (SSW) filled the Delfín, Salsipuedes, and Tiburón basins, while to the southeast it was found between 150 and 350 m. Pacific Intermediate Water did not cross the sills. SSW enriches the surface water of the MIR with DIC when it increases in volume and when mixed with GCW by tidal effects. This contribution decreases towards summertime, when SSW sinks and the volume of GCW increases. In winter, GCW had three water types associated with oceanographic mixing processes and in combination with the presence of SSW. There was a strong DIC vs temperature relationship, which can be applied to analyze the carbon dynamics in the MIR, both at the surface using satellite imagery and vertically to simulate physical processes.Key words: dissolved inorganic carbon, Gulf of California, vertical mixing, Ballenas Channel, coastal DIC studies. RESUMEN.En la región de las grandes islas (RGI) del golfo de California la mezcla por mareas juega un papel muy importante en la distribución de propiedades disueltas. Aunque la variabilidad temporal de las masas de agua está ligada con la dinámica oceanográfica de la región, su importancia no ha sido considerada. En este trabajo se estima el efecto de la dinámica de las masas de agua sobre la distribución espacial y variación estacional del carbono inorgánico disuelto (CID) en la RGI, con especial énfasis en el canal de Ballenas, durante el invierno de 2002, la primavera de 2003 y el verano de 2004. El Agua del Golfo de California (AGC) se encontró en toda la superficie en los primeros 100 m de profundidad. Por debajo del AGC, el Agua Subsuperficial Subtropical (ASS) llenó las cuencas Delfín, Salsipuedes y Tiburón, mientras que en el sureste se encontró entre 150 y 350 m. El Agua Intermedia del Pacifico no atravesó los umbrales. Se encontró que el ASS enriquece de CID las aguas superficiales de la RGI cuando aumenta su volumen y cuando se mezcla con el AGC por efecto de las mareas. El aporte disminuye hacia el verano, cuando el ASS se hunde al mismo tiempo que el volumen de AGC aumenta. En invierno, el AGC presentó tres tipos de agua asociadas a los procesos de mezcla y en combinación con la presencia de ASS. Se encontró también que en la RGI la relación CID vs temperatura podría aplicarse en futuros estudios para analizar la dinámica del carbono en la RGI, tanto en la superficie mediante imágenes de satélite como en la verti...
