    In: The Geology of the South Shetland Islands
    Description / Table of Contents: King George Island is almost entirely composed of igneous rocks; four volcanic episodes and one intrusive phase are represented. The oldest volcanics, which are believed to be Upper Jurassic in age, form a calc-alkaline suite with an andesite-rhyolite association. Recent field investigations indicate there is no evidence for the extensive areas of sedimentary rocks previously recorded. The presence of regionally metamorphosed xenoliths in the Jurassic Volcanos indicates that they rest upon a Basement Complex. The early Tertiary Andean Intrusive Suite, which is petrographically similar to that of Graham Land, forms an axial core to the island. The majority of the Jurassic Volcanics have been metasomatized by these intrusions and the significance of the resultant secondary minerals is discussed. A linear pattern of Tertiary and Quaternary vulcanicity has been demonstrated and lavas of three distinct episodes are described. One of these volcanic groups is of unknown age, whilst the others are known to be Middle Miocene and Recent. The lavas include dominant pyroxene-andesites, basaltic andesites, olivine-basalts and rare trachyandesites. The petrogenesis of the volcanic site is discussed and crystal separation is suggested as the most important factor in their evolution. A geological map, compiled from all the available rock collections and field notes, shows the distribution of the volcanic and intrusive groups.

    Description / Table of Contents: Small-scale laboratory experiments were conducted on model bridge piers in the CRREL test basin. The experiments were performed by pushing model ice sheets against structures and monitoring the ice forces during the ice/structure interaction. The parameters, varied during the test program, were the geometry of the bridge piers and the velocity, thickness, and flexural strength of the ice. The results are presented in the form of ice forces on sloping and vertical structures with different geometries. During ice action on sloping structures, a phenomenon of transition of failure mode from bending to crushing was observed as the ice velocity was steadily increased.

    Description / Table of Contents: The ice discharge through an opening in an ice control structure was documented to be a function of the floe size, ice type, ice floe conditions and vessel direction. The model data for the average ice discharge per vessel transit scaled to prototype values compared favorably with data taken at the St. Marys River ice control structure (ICS). The model results of the force measurements were also consistent with data taken at the St. Marys ICS. The dynamic loading conditions were independent of vessel direction. The dynamic loading to the structure using 3 types of ice (plastic, natural and urea-doped) showed a considerable difference in their means and standard deviations. The urea-doped ice was evaluated for dynamic loading conditions, and reasonable peak values of 3 to 5 times the mean load at each measuring position were recorded, independent of vessel direction. It appears that synthetic random ice floes may be used in model studies where ice discharge through an opening in a structure needs to be documented. This study shows the synthetic random ice floe discharge to fall reasonably within the values obtained for natural ice discharge for both rafted and non-rafted ice fields above the ICS. However, the question of whether synthetic ice can be used for analyzing force distributions and dynamic force loading criteria cannot be fully answered at this time because the load distributions of the synthetic and natural floes appear to differ.
