The nightside ionospheric response to IMF by changes
A sharp latitudinal gradient in the Doppler spectral width is often observed in the nightside data from the SuperDARN HF radars. We use an excellent conjunction between the Halley HF […]

High latitude Eocene climate deterioration: evidence from the northern Antarctic Peninsula
Read more of: High latitude Eocene climate deterioration: evidence from the northern Antarctic PeninsulaClay mineral, sedimentological and geochemical data show that the northern Antarctic Peninsula (Seymour Island, La Meseta Formation) experienced a climatic deterioration from very warm, non-seasonally wet conditions at the end […]

Pétrologie et géochimie des basaltes de Murta : une éruption sous-glaciaire dans les Andes patagoniennes (46° lat. S.), Chili. Relation avec la subduction de la ride du Chili
Read more of: Pétrologie et géochimie des basaltes de Murta : une éruption sous-glaciaire dans les Andes patagoniennes (46° lat. S.), Chili. Relation avec la subduction de la ride du ChiliThe Holocene Murta basalts represent a small volume monogenetic centre located in the northern Patagonian Andes at the latitude of the Chile Triple Junction. These basalts show morphological evidence of […]

Note on the trophic relationships of the stauromedusa Haliclystus antarcticus from subantarctic South Georgia
Read more of: Note on the trophic relationships of the stauromedusa Haliclystus antarcticus from subantarctic South GeorgiaStauromedusae are cnidarians that have attracted relatively little ecological study, especially in the southern hemisphere. They are Scyphozoa that develop directly from the scyphistoma, and each consists of a calyx […]
