Suprabenthic euphausiids and mysids from the South Shetland Islands and the Bransfield Strait, Southern ocean (BENTART-95 cruise)

During the austral summer 1995, the suprabenthic assemblages from 24 stations (45–649 m water depth) located around the South Shetland Islands and in the Bransfield Strait were sampled with a Macer-GIROQ sled. The purpose of this paper is to describe the structure of two main crustacean groups (euphausiids and mysids) in the near-bottom water layers sampled by the sled and to focus on the life history of two dominant mysid species from these areas (Mysidetes posthon and Antarctomysis maxima). The distribution and the main factor structuring populations in the investigated area are discussed.
