| A 40 m long sediment core covering the 1000-9600 years BP period was retrieved from the Dumont d'Urville Trough off Adelie Land, East Antarctica, during the MD 130-Images X-CADO cruise. This sedimentary sequence allows the documentation of changes in climate seasonality during the Holocene. Here we show preliminary results of diatom communities, lithic grain distribution and titanium content measured on two 30 cm long sequences of thin sections. The two sequences originate from two different climate regimes, the colder Neoglacial and the warmer Hypsithermal. Proxies were measured at microscale resolution on 25 laminations for the Neoglacial and 14 laminations for the Hypsithermal. The two sequences reveal alternating light-green and dark-green laminae.... |

| A new Antarctic lysianassid amphipod, Orchomene hureaui sp.n. from Addlie Land is described and illustrated. The male is unknown. The 2 females were from the stomach of an Adelie penguin. Its epistome is straight and is just in front of the upper lip. The lateral cephalic lobes are rounded and eyes are present. Coxa I is trapezoidal and wide distally, the carpus of gnathopod I shorter than propodite and with no postero-distal lobe, the palm is transverse, slightly convex and deeply toothed. Gnathopod II is subchelate and coxa V has subequal inferior lobes. Uropod III has long setose branches and the telson is divided. The ecology and relations with other Orchomene spp are discussed. |
