Late-Summer Abundance and Distribution of Marine Birds in Kasegaluk Lagoon, Chukchi Sea, Alaska

Oil and gas drilling programs in the Alaska Chukchi Sea were carried out on leases offshore from Kasegaluk Lagoon in 1989-91, and further exploration and development activities in this area are likely in future years. We conducted aerial surveys between late July and early September 1989-91 to determine the distribution and abundance of marine birds in the Kasegaluk Lagoon area. We hypothesized that Kasegaluk Lagoon supported an avifauna similar to that found in other lagoon systems in arctic Alaska. In fact, the richness and diversity of bird species using Kasegaluk Lagoon were greater than in lagoon systems in the Beaufort Sea. Brant (Branta bernicla) was the most abundant species in Kasegaluk Lagoon compared to lagoons in the Beaufort Sea, where the Oldsquaw (Clangula hyemalis) is the dominant species. Several other species or species groups, such as Glaucous Gull (Larus hyperboreus), Arctic Tern (Sterna Paradisaea), small shorebirds (mainly Calidris and Phalaropus), and Lesser Snow Goose (Chen caerulescens) were also relatively abundant in Kasegaluk Lagoon.Key words: waterbirds, aerial surveys, lagoon ecosystems, Kasegaluk Lagoon, Chukchi Sea, Beaufort Sea, AlaskaDes programmes de forage pétrolier et gazier ont été exécutés dans la portion alaskienne de la mer des Tchouktches, sur des concessions au large de l'étang côtier Kasegaluk de 1989 à 1991, et on prévoit que d'autres activités reliées à l'exploration et au développement auront lieu à cet endroit dans les années à venir. On a effectué des relevés aériens entre la fin de juillet et le début de septembre de 1989 à 1991, afin de déterminer la distribution et l'abondance des oiseaux marins dans la région de l'étang côtier Kasegaluk. On avait émis l'hypothèse que cet étang était le refuge d'une avifaune semblable à celle qui se trouve dans d'autres systèmes lagunaires dans l'Alaska arctique. En réalité, la richesse et la diversité des espèces d'oiseaux utilisant l'étang Kasegaluk étaient supérieures à celles des systèmes lagunaires de la mer de Beaufort. La bernache cravant (Branta bernicla) représentait l'espèce la plus abondante de l'étang côtier Kasegaluk comparé aux étangs côtiers de la mer de Beaufort, où le canard kakawi (Clangula hyemalis) est l'espèce dominante. Plusieurs autres espèces ou groupes d'espèces, comme le goéland bourgmestre (Larus hyperboreus), la sterne arctique (Sterna paradisaea), les petits oiseaux de rivage (surtout Calidris et Phalaropus) et la petite oie blanche (Chen caerulescens) étaient relativement abondants dans l'étang côtier Kasegaluk.Mots clés : oiseaux aquatiques, relevés aériense,écosystèmes lagunaires, étang côtier Kasegaluk, mer des Tchouktches, mer de Beaufort, Alask

Conceptualization of Space within the Tang Landscape Quatrain

The thesis explores the poet’s creation of conceptualized space within the Tang landscape quatrain in the Tang dynasty (618-907) by usage of literary techniques, the focal point being that of temporal and spatial progression to create dynamic and static space. “Space” within the thesis is defined as the “matrix of which forms emerge, medium in which they are related,” a mentalization and visualization of breadth, depth, and width created within the artistic medium. I argue that the concision of Classical Chinese allows the poet to transcend the linguistic limitations imposed by rules of verse to create boundless, semantic space by constructing vivid tableaus of scene and emotion. In Classical Chinese, there are no verb tenses, no indication of plurality in nouns, and no gender or cases for pronouns. The poet must use language to mold intangible form into tangible existence. The deliberate application of ambiguity is a vital component in the creation of multi-layered dimensions of space within Classical Chinese poetry. The Tang dynasty is often known as the golden age of Chinese poetry, dominated by the emergence of new innovations and form as poetry writing became more ubiquitous. The breaking from traditional rules of verse allowed the poet to uniquely utilize space to further their reflections in their poetry. The thesis examines the poet’s creation of spatiality through two lenses of spatiality: creation of external space through landscape, and secondly, the creation of internal space through mental reflection upon that very landscape. The Tang poet approaches the landscape not only as a place setting, but also as an entire subliminal entity in which he aims to capture with his senses and perceptions to create space in which the reader can visualize. The descriptive poetry of the landscape quatrain is simply not a limitation as a medium of visual communication as Tang poets infuse layers of meaning with the economy of a few characters. The significance of framing this study within traditional poetic concerns is to understand the intersections of nature, landscape, literary technique, and aesthetic experience. There has been much academic scholarship on the poetry of the High Tang by scholars such as James J. Y. Liu, Stephen Owen, Burton Watson, just to name a few. However, the objective of this thesis is to offer a new perspective through the lens of spatial creation. Quatrains written by famous Tang poets, Li Bai (701-762), Wang Wei (701-761), and Meng Haoran (689-740) are selected to illustrate how the technique of progression is uniquely utilized to create depth and perspective of space.Asian Studie

Quenched noise and over-active sites in sandpile dynamics

The dynamics of sandpile models are mapped to discrete interface equations. We study in detail the Bak-Tang-Wiesenfeld model, a stochastic model with random thresholds, and the Manna model. These are, respectively, discretizations of the quenched Edwards-Wilkinson equation with columnar, point-like and correlated noise, with the constraint that the interface velocity is either zero or exactly one. The constraint, embedded in the sandpile rules, gives rise to another noise component. This term has for the Bak-Tang-Wiesenfeld model long-range on-site correlations and reveals that with open boundary conditions there is no spatial translational invariance.Comment: 4 pages, 3 figure

Moment analysis of the probability distributions of different sandpile models

We reconsider the moment analysis of the Bak-Tang-Wiesenfeld and the Manna sandpile model in two and three dimensions. In contrast to recently performed investigations our analysis turns out that the models are characterized by different scaling behavior, i.e., they belong to different universality classes.Comment: 6 pages, 6 figures, accepted for publication in Physical Review
