Fig. 1. Schematic representation of the depth-averaged ocean circulation in the Southwestern Atlantic Ocean (adapted from Matano et al., 2010) showing the geographical locations of tagging of Galeorhinus galeus [Triangle, Nuevo Gulf (NG), 42°30'S, 65°55'W, depth 100 m], newest recapture in Uruguayan shelf waters (Star, 35°30'S, 51°48'W – depth 290 m) and the two old recapture sites (Circle, Mar del Plata, 38°24'S, 57°18'W, depth 40 m and Canal Culebra, 40°24'S, 62°06'W - depth 15 m, Irigoyen et al., 2015). Additional geographical locations are indicated with acronyms: SMG = San Matías Gulf, VP = Valdés Peninsula, AB = Anegada Bay, PM = Punta Médanos, STSF = Subtropical Shelf Front. The thick curved lines represent the path of the major ocean currents. The black line is the 200m isobath. Colours indicate bottom temperature (a, c) and bottom salinity (b, d) and black arrows indicate the bottom shelf circulation extracted from a numerical model (Palma et al., 2008). The yellow and gray lines in the left panels indicate the 11 and 17 °C isotherms respectively. The red and cyan lines in the right panels indicate the 33.93 and 33.5 isohalines.
