title: Oxygen isotopic paleotemperatures across the Runangan—Whaingaroan (Eocene—Oligocene) boundary in a New Zealand shelf sequence

authors: Burns, David A.

subjects: paleotemperatures

abstract: Oxygen isotopic compositions of the tests of mainly benthic foraminifera, from sections of conformable Late Eocene (Runangan) to Early Oligocene (Whaingaroan) shelf mudstones, at both Cape Foulwind and Port Elizabeth, western South Island, indicate. that shelf sea paleotemperatures followed the global open-ocean trend towards a Paleogene minimum near the Eocene-Oligocene boundary. Throughout the latest Eocene, temperatures declined steadily by 3°C, showed a temporary minor warming at the Eocene-Oligocene boundary, dropped sharply by 2°C in the Early Oligocene, and ameliorated significantly later in the Early Oligocene. The qualitative temperature trends for New Zealand shelf waters at this time are similar to those inferred from earlier paleontologic syntheses and limited oxygen isotopic work, but involve a range of temperatures within the warm and cool temperate climatic zones and an absolute temperature depression across the Eocene-Oligocene boundary of only 5°C (from about 17 to 12°C). Results are consistent with isotopic paleotemperatures determined from deep-sea sediment cores south of New Zealand where the cooling is inferred to mark the onset of production of Antarctic bottom waters at near-freezing temperatures. © 1981 Taylor & Francis Group, LLC.

title: SEPSen: Semantic event processing at the sensor nodes for energy efficient wireless sensor networks

authors: Kasi, Mumraiz Khan

subjects: semanitcs

abstract: Traditionally in WSNs, the sensor nodes are used only for capturing data that is then later analyzed in the more powerful gateway nodes. This requires a continuous communication that wastes energy at the sensor nodes and greatly reduces the overall network lifetime. We propose a semantic-based in-network data processing that reduces energy consumption and improves the scalability of heterogeneous sensor networks. Ontology fragments in each sensor node help identify the data routed through the sensor network. We have adapted a matching algorithm to process a changing knowledge base. Simulation results show that the networks' energy consumption is considerably reduced.

title: Travel writing and the first Marists in New Zealand

authors: Jennings, William

subjects: travel writing

abstract: French Marist missionaries arrived in New Zealand in 1838 and travelled extensively throughout the country during the next two decades. The letters they sent to France, now published in Girard's Lettres recues d'Ocanie (2009), include accounts of journeys that reveal the Marists' different perspectives of New Zealand's landscape and inhabitants. French romanticism and their religious vows emphasised a spiritual connection with the landscape, in sharp contrast with prevailing utilitarian European views. The Marists' status as Frenchmen in a British colony meant they encountered two alterities: British and Maori. Influenced by the noble savage of the French Romantics and by anti-Protestant bias, the Marists portrayed Maori favourably, reserving their more hostile comments for the British missionaries.
