L'A. s'élève contre l'usage fréquent aux Etats-Unis des expressions Middle Atlantic Bight et South Atlantic Bight pour désigner la côte des Middle Atlantic States et celle des états du Sud-Est, de la Caroline du Nord à la Floride. Les termes
employés conduisent à des aberrations dans les indexations par ordinateur. Il propose de leur subsistuer les formules : Off the Middle Atlantic States et Coastal Waters of the Southern US Atlantic States. - (FC)
Analysis of the benthonic foraminiferal faunas in two sediment cores recovered from the Vema and Hunter Channels in the western South Atlantic shows that the level of the transition between deep and bottom waters shallowed sharply about 700,000 yr
ago. This rise indicates a sharp, sustained increase in the volume of bottom water flowing through the South Atlantic after this time. Prior to about 700,000 yr ago, the amount of Antarctic Bottom Water entering the western South Atlantic was greatly
reduced and Circumpolar Deep Water apparently accounted for the bulk of northward flow. Production of southward-flowing North Atlantic Deep Water seems not to have been affected. The timing of this change in circulation regime suggests a possible causal

The deglacial pattern of a high-resolution alkenone-derived temperature record from the southeastern tropical Atlantic was compared with one from the northeastern subtropical Atlantic. During Termination 1b, surface waters in the eastern tropical
Atlantic (6°S) reached modern temperatures, whereas those in the subtropical northeastern Atlantic (21°N) were still considerably colder than today. This asymmetrical warming may reflect meltwater-induced reductions in the northward heat transport and helps
Plate kinematic implications of Atlantic Equatorial fracture zone trends

We present a plate kinematic evolution of the South Atlantic which is based largely on the determination of the equatorial fracture zone trends between the African and South American continental margins. Four main opening phases are dated by oceanic
magnetic anomalies, notably MO, A34 and A13, and are correlated with volcanism and tectonic events on land around the South Atlantic Ocean. The Ceara and Sierra Leone rises are probably of oceanic origin and were created 80m.y. ago or later in their present

Geodynamical processes and interrelations between the opening of the Atlantic ocean, the development of transition zone and the Central-European depression are analyzed by means of investigations of the transition zone between the Central-European
depression and the Atlantic ocean. A scheme of the depths of the asthenospere-lithospere border is discussed. (HL).
