INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1. The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)” . I f it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image o f the page can be found in the adjacent frame. I f copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand comer o f a large sheet and to continue from left to right in equal sections with small overlaps. I f necessary, sectioning is continued again—beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed.

ABSTRACT: In Snow Hill and Seymour islands the lower Maastrichtian, basal part of the López de Bertodano Formation, rests on a high relief, erosi- ve surface elaborated in the underlying Snow Hill Island Formation. Mudstone-dominated beds with inclined heterolithic stratification dominate the basal strata of the López de Bertodano Formation. They consist of rhythmical alternations of friable sandy- and clayey- mudstone couplets, with ripple cross lamination, mud drapes, and flaser bedding. They are characterized by a marked lenticular geometry, reflecting the filling of tide-influenced channels of various scales and paleogeographic positions within a tide-dominated embayment or estuary. Major, sand-rich channel fills, up to 50-m thick, bounded by erosive surfaces probably represent inlets, located on a more central position in the estuary. Minor channel fills, 1- to 3-m thick, associated with offlapping packages with inclined heterolithic stratification pro- bably represent the lateral accretion of point bars adjacent to migrating tidal channels in the upper estuary. Both types of channel fills bear relatively abundant marine fauna, are intensively bioturbated, and are interpreted as a network of subtidal channels. In southwestern Snow Hill Island, the minor offlapping packages have scarce marine fossils and bear aligned depressions interpreted as poor preserved dinosaur footprints.

What is the role of the GN in issuing wildlife research permits? On June 1, 1999, Nunavut became Canada’s newest territory. Since its creation, interest in studying its natural resources has steadily risen. Human demands on animals and plants can leave them vulnerable, and wildlife research permits allow the Department to keep records of what, and how much research is going on in Nunavut, and to use this as a tool to assist in the conservation of its resources. The four primary purposes of research in Nunavut are: a. To help ensure that communities are informed of scientific research in and around their communities; b. To maintain a centralized knowledgebase of research activities in Nunavut; c. To ensure that there are no conflicting or competing research activities in Nunavut; and d. To ensure that wildlife research activities abide by various laws and regulations governing the treatment and management of wildlife and wildlife habitat in Nunavut. 2. How is this process supported by the Nunavut Land Claims Agreement? Conservation: Article 5.1.5 The principles of conservation are: a. the maintenance of the natural balance of ecological systems within the Nunavut Settlement Area; b. the protection of wildlife habitat; c. the maintenance of vital, healthy, wildlife populations capable of sustaining harvesting needs as defined in this article; and d. the restoration and revitalization of depleted populations of wildlife and wildlife habitat.

  • New Longevity Record for Ivory Gulls (Pagophila Eburnea) and Evidence of Natal Philopatry M.L
    ARCTIC VOL. 65, NO. 1 (MARCH 2012) P. 98 – 101 New Longevity Record for Ivory Gulls (Pagophila eburnea) and Evidence of Natal Philopatry M.L. MALLORY,1 K.A. ALLARD,2 B.M. BRAUNE,3 H.G. GILCHRIST3 and V.G. THOMAS4 (Received 25 April 2011; accepted in revised form 2 August 2011) ABSTRACT. Ivory gulls (Pagophila eburnea) have been listed as “endangered” in Canada and “near threatened” interna- tionally. In June 2010, we visited Seymour Island, Nunavut, Canada, where gulls were banded in the 1970s and 1980s. We recaptured and released two breeding gulls banded as chicks in 1983, confirming natal philopatry to this breeding colony. These gulls are more than 28 years old, making the ivory gull one of the longest-living marine bird species known in North America. Key words: ivory gull, Pagophila eburnea, Nunavut, banding RÉSUMÉ. La mouette blanche (Pagophila eburnea) figure sur la liste des espèces « en voie de disparition » sur la scène canadienne et des espèces « quasi menacées » sur la scène internationale. En juin 2010, nous sommes allés à l’île Seymour, au Nunavut, Canada, où des mouettes avaient été baguées dans le courant des années 1970 et 1980. Nous avons recapturé et relâché deux mouettes reproductrices qui étaient considérées comme des oisillons en 1983, ce qui nous a permis de confirmer la philopatrie natale de cette colonie de nidification. Ces mouettes blanches ont plus de 28 ans, ce qui en fait l’un des oiseaux aquatiques vivant le plus longtemps en Amérique du Nord. Mots clés : mouette blanche, Pagophila eburnea, Nunavut, baguage Traduit pour la revue Arctic par Nicole Giguère.

The probable sources of these sediments were generated in Carboniferous to Early Paleogene times (,315 to 60 Ma). The total depths of individual James Ross Basin formations are discussed. The AFT data were modelled, and the thermal history model was reconstructed for samples from Seymour Island. The first stage after a period of total thermal annealing (when the samples were above 1208C) involved Late Triassic cooling (,230 to 200 Ma) and is followed by a period of steady cooling through the whole apatite partial annealing zone (PAZ, 60–1208C) to minimum temperature in Paleocene/Early Eocene. The next stage was the maximum burial of sedimentary rocks in the Eocene (,35 Ma, 1.1–1.8 km) and the final cooling and uplift of Seymour Island sedimentary rocks at ,35 to 20 Ma.

  • Distribution of Marine Palynomorphs in Surface Sediments, Prydz Bay, Antarctica
    DISTRIBUTION OF MARINE PALYNOMORPHS IN SURFACE SEDIMENTS, PRYDZ BAY, ANTARCTICA Claire Andrea Storkey A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree Masters of Science in geology School of Earth Sciences Victoria University of Wellington April 2006 ABSTRACT Prydz Bay Antarctica is an embayment situated at the ocean-ward end of the Lambert Glacier/Amery Ice Shelf complex East Antarctica. This study aims to document the palynological assemblages of 58 surface sediment samples from Prydz Bay, and to compare these assemblages with ancient palynomorph assemblages recovered from strata sampled by drilling projects in and around the bay. Since the early Oligocene, terrestrial and marine sediments from the Lambert Graben and the inner shelf areas in Prydz Bay have been the target of significant glacial erosion. Repeated ice shelf advances towards the edge of the continental shelf redistributed these sediments, reworking them into the outer shelf and Prydz Channel Fan. These areas consist mostly of reworked sediments, and grain size analysis shows that finer sediments are found in the deeper parts of the inner shelf and the deepest areas on the Prydz Channel Fan. Circulation within Prydz Bay is dominated by a clockwise rotating gyre which, together with coastal currents and ice berg ploughing modifies the sediments of the bay, resulting in the winnowing out of the finer component of the sediment. Glacial erosion and reworking of sediments has created four differing environments (Prydz Channel Fan, North Shelf, Mid Shelf and Coastal areas) in Prydz Bay which is reflected in the palynomorph distribution. Assemblages consist of Holocene palynomorphs recovered mostly from the Mid Shelf and Coastal areas and reworked palynomorphs recovered mostly from the North Shelf and Prydz Channel Fan.

The British Williams exploration party led by Captain William Smith discovered the northwest coast of the Antarctic Peninsula. The Russian Vostok and Mirnyy expedition led by Thaddeus Thadevich Bellingshausen sighted parts of the continental coast (Dronning Maud Land) without recognizing what they had seen. They discovered Peter I Island in January of 1821. • 1841 James Clark Ross sailed with the Erebus and the Terror through the ice in the Ross Sea, and mapped 900 kilometres of the coast. He discovered Ross Island and Mount Erebus. • 1892-93 Financed by Chr. Christensen from Sandefjord, C. A. Larsen sailed the Jason in search of new whaling grounds.
