The effect of Falkland Current inflows on offshore ontogenetic migrations of the squid Loligo gahi on the southern shelf of the Falkland Islands

Water density pathways for shelf/slope migrations of squid Illex argentinus in the Southwest Atlantic

“…Two main water masses were present in the area studied, Patagonian Shelf water mass (PSW) transported by the Argentinean Shelf drift from the northwest, and Sub-Antarctic Superficial water mass (SASW) transported from the southeast by the Falkland Current, their characteristics being similar to those described earlier by Arkhipkin et al (2004) (Fig. 3).…”

Geomorphology and shallow structure of a segment of the Atlantic Patagonian margin

“…The presence of the ice rafted sediments on the eastern edge of the Perito Moreno Terrace, the similar sediments recovered by Ewing and Lonardi (1971) Today the Falkland/Malvinas Current breaks into two branches south of the Falkland/Malvinas Islands, a stronger eastern branch that passes east of the islands and a western weaker branch that passes west of the islands (Arkhipkin et al, 2004). It is the 100 km wide eastern branch that impinges on the Patagonian upper slope that influences sedimentation on the middle slope.…”

A review of cephalopod–environment interactions in European Seas

“…Agnew et al (2000) showed a negative correlation between SST and the strength of the recruitment of L. gahi, with a delay of 6 months. Arkhipkin et al (2004) studied the effects of the Falkland current inflows on the ontogenetic migrations of L. gahi and showed that stronger flows of the Falkland current onto the western part of the southern Falkland Shelf induce stronger outflows of warmer and less saline shelf waters, and correspondingly greater offshore movements of squid. Arkhipkin et al (2006) identified the role of the Falkland current in the dispersal of L. gahi along the Patagonian shelf.…”
