Abundance (ind/m3) distribution of Drepanopus forcipatus during March 2006 and June 2006 in the Beagle Channel.
In this area the surface water temperature ranges from 4.2-4.3°C in August to 8.9-9.8°C in Juanary, while the salinity ranges from 26.7 psu in November-December to 31.3 psu during July.
According to Klöser (1996) the Channel between the Isla Navarino and the Isla Grande de Tierra del Fuego has the character of a semi- enclosed water body. |
