Spatial distribution of cephalopod paralarvae in San José Gulf (Northern Patagonia, Argentina): The role of tidal circulation in larval dispersal

“…During ebb tides seawater is expelled through the mouth to SMG, forming eddies moving northwards for up to 100 km, reaching the center of SMG (Amoroso and Gagliardini, 2010). Considering that the mean tidal amplitude of SJG is 6 m and that the mean depth of the gulf is 40 m, the volume of seawater flowing through the mouth in every rising and ebb tide represents approximately 15% of its total volume (Rivas, 1990). Furthermore, since the process is asymmetrical between domains, this figure must be even higher for the western domain, explaining the homogeneous structure of the water column in it.…”

“…It has a semidiurnal tidal pattern, with a range variable from 6 m to 9 m and a maximum depth of 4 m at low tide. This conditions (Rivas, 1990(Rivas, , 1994. Small pebbles mussel Brachydontes rodriguezii constitute the main substrata.…”

Revision of the population structuring of Illex argentinus (Castellanos, 1960) and a new interpretation based on modelling the spatio‐temporal environmental suitability for spawning and nursery

“…Also, taking into account the extension of the geographic distribution of the species, a 1°‐latitude × 1°‐longitude spatial resolution was used. For each spatial unit, the SST temporal data series was fitted by least‐square nonlinear regression to the function: where SST( t ) is the estimated mean SST for month ‘ t ’, T 0 is the annual mean temperature, T 1 is the amplitude of the seasonal cycle, w = 2π/12 month −1 , t is the month (starting from January) and t 0 is the phase that coincides with the month of the year in which temperature is maximum (Rivas, 1994; Cinti et al. , 2004).…”

Embryonic survival in each month of the year at each spatial unit was then estimated based on the function of Sakai et al (1999) and the mean SST estimated by the regression model.…”
