the Last Glacial Maximum. Ice drainage within the bay and on the inner continental shelf was strongly influenced by tectonic fabric. The glacially sculptured geomorphic features within MargueriteBay co-exist with anastomosing, radial and relatively
Geomorphic features indicate that both glacial and melt-water erosion characterize the onset area of the ancestral Marguerite Ice Stream. The large size of these features indicates that they formed over repeated glacial cycles, most recently during
straight channels, which become increasingly focused in a seaward direction. This implies that a well organized subglacial drainage system existed within the bay at some point in the past.
and a very thin layer of sediment over crystalline basement or older sediments. A reconstruction of the glacial history of MargueriteBay since the last glacial maximum shows grounded ice filling the bay in late Wisconsin time. Rising sea level caused
Piston cores and single-channel seismic reflection data were collected during the Deep Freeze 85 and 86 expeditions to determine the late Quaternary history of the area. Seismic data in the bay show a rugged seafloor, with numerous deep troughs
The Bai-u season was reconstructed with the aid of weather records entered in old diaries between the beginning of the eighteenth century and 1895. The duration of the Bai-u season revealed a strong positive correlation with the end of the Bai-u

This article reviews previous explanations and ideas on the origin of Taranaki Bay in early New Zealand maps. The bay was first depicted on an 1826 French map drawn by Jules de Blosseville.

Strategic territory and territorial strategy: the geopolitics of Walvis Bay's reintegration into Namibia
Administration ; Colonisation ; Conflit ; Enclavement ; Géographie politique ; Géopolitique ; Histoire ; Namibie ; Walvis Bay
Discussion of the focus and concerns of critical geopolitical analysis, with reference to the contested enclave of Walvis Bay. The eventual reintegration of Walvis Bay into Namibia in 1994 represents the final episode in a long and bitter liberation
struggle waged by Namibians against South African occupation. The paper charts the history of Walvis Bay's colonization and the conflicting claims of sovereignty. The principal focus is he process of bilateral negotiation and changes to the status following
The purpose of this report is to define the sedimentary characteristics of the subsurface lithologic units of the Abu Quir bay and interpret their geological evolution. These information would help in predicting the best site for installing a new
platform at Abu Quir bay. Also it can be useful to search for borrow sand used for beach nourishment.

Three boundary layer models are applied to a wind energy siting investigation in the Saldanha Bay area. The different models were then tested and results compared. Favourable results were obtained for further development of the models. - (AJC)
Afforestation, fire, and vegetation management in the East Bay Hills of the San Francisco Bay area
Devastating fires destroyed much property in 1923 and 1991 in the hills above the bay cities of Oakland and Berkeley (California). In 1991, over 3 300 houses were destroyed, 25 people were killed and 5 000 people rendered homeless. A main reason

Excavations in 1988 at two of the sites explored previously, the Avenue Q(35CLT13) and Palmrose (35CLT47) sites, provided an opportunity to test the Seaside bay hypothesis. The evidence suggests that the sites bordered a small bay during the time

Deuxième port canadien après Vancouver pour le tonnage manipulé, Thunder Bay (Ontario) jouit désormais de sa localisation favorable à la tête de navigation des Grands Lacs. Depuis l'émergence de la Nouvelle Voie Maritime du Saint-Laurent en 1959
, Thunder Bay est devenu un port accessible aux navires de haute mer. Il jouit dorénavant du monopole de la manutention du vrac entre les Prairies et le Canada central. (ALS).
New constraints on the evolution of Carolina Bays from ground-penetrating radar

Ground-penetrating radar (GPR) data for the Savannah River Site (SRS) in the Upper Coastal Plain of South Carolina, combined with geological, archaeological, and ecological data place new constraints on the evolution of Carolina Bays. Extant SRS bay
morphology formed mainly during the Holocene and did not involve migration of bays across the landscape. The results are interpreted to develop a model of bay evolution subsequent to the formation of the initial depression.
Wave energy and clast transport in eastern Tasman Bay, New Zealand
Dynamique littorale ; Gravier ; Littoral ; Nouvelle-Zélande ; Pacifique Sud ; South Island ; Tasman Bay ; Transport sédimentaire ; Vague ; Vent
The aim of this paper is to determine whether wave energy in Tasman Bay is sufficient to initiate clast transport along the gravel platforms. In this study, wind data form Nelson airport and measured wave data from Cable Bay and Mackay Bluff
are used in conjunction with 2 different mathematical models of clast transport. Values calculated from each of these models are compared with the present wind and wave environment of Tasman Bay. While the mathematical models can only provide approximations
because of differences in bathymetry and wave morphology, they will provide a calibrated scale of clast movement along eastern Tasman Bay.
