Ce volume couvre les années 1947-1974 et fait suite au Premier Volume, publié en 1948 et réimprimé en 1973. Une bibliographie annuelle est publiée, à partir de l'année 1975, dans la revue Finisterra. (SD).
The oxygen-isotope record from fossil foraminifera in deep-sea sediments is commonly used as a proxy for global ice volume. The linkage between O and ice volume, however, is probably nonlinear. The AA. have developed a simple numerical model
of the isotopic response of the oceans to ice-volume change. They illustrate the response of their model to simple hypothetical ice-volume transitions of ice growth and ice decay. Sensitivity tests are illustrated for all model parameters. The results suggest
that oxygen-isotope records reproduce the general patterns on ice-volume change fairly accurately. The foraminiferal isotope record, however, may misrepresent the true amplitude of the ice-volume signal and lag true ice volume by 1000 to 3000 yr.

Quaternary of South America Antarctic peninsula. Volume 1.
First volume of an annual scientific publication related to the problems of the Quaternary of South America with a strong emphasis in the paleoenvironmental and paleoclimatic approach. The various papers are reviewed separately.
In this study, relative volumes of stones and gravel were investigated in the top soils, i.e. down to 30 cm depth, of five Swedish arable sites. Bulk density and gravel volume were determined by soil coring and stone volume using the rod penetration
method. A function for estimation of relative stone volume from mean penetration depth was developed. The results showed that although the relative volumes of stones and gravel were small, at most 8%, neglecting the volume occupied by rock fragments led
to an overestimation of C and N stocks by 8-9%. It was concluded that the inclusion of stone and gravel volume of arable soils may be important if nutrient stocks of different sites are compared, or the effects of land use changes are scaled up to regional or global

L'A. étudie le procédé de détermination automatique des volumes représentés sur les cartes d'isolignes normalisées. Parmi les objectifs les plus typiques on note la détermination du volume des glaciers, des volumes des précipitations, des réserves
de minéraux utiles, etc. 2 procédés de détermination: au moyen des plans de section horizontaux d'une part, des plans de section verticaux d'autre part. Le plus économique et le plus efficace est le second, car le calcul du volume est immédiat. (MMB).
Evaluating proxies for estimating subaerial beach volume change across increasing time scales and various morphologies
This study assesses the impacts of morphologic variations, associated with beach cusps and nourishment material, on volume change estimates from profiles and shoreline change at 0.5 to 3.5 year time periods. Volume changes at the edges
of nourishment areas are not captured well by profiles. When the nourishment material is graded to a ramped morphology, which minimizes across-beach morphologic variability, the shoreline-change proxy does accurately estimate volume changes. Both proxies estimate
volume changes inaccurately at beaches where volume changes oscillate between erosion and accretion on both short and long time scales because the magnitude of small-scale changes in volume from the formation and erosion of morphologic features
, such as cusps and berms, will always be similar to the longer-term net volume change. This study suggests that decadal records of shoreline change, which are commonly developed using aerial photography, can be used to help identify the best proxy for estimating
volume change; however, recent anthropogenic modifications that impact patterns of beach sedimentation, including nourishment, terminal groins, and inlet-channel dredging, makes decadal records less useful.
