Late Paleocene foraminiferal faunas with Chapmanina and Reticulophragmium from offshore southeastern Australia: a Tethyan influence

Samples from off southern New South Wales in approximately 1750 m water depth have yielded late Paleocene faunas of benthic and planktonic foraminifera and other invertebrates. Two faunal associations with a strong Tethyan influence, dominated respectively by Chapmanina conjuncta sp. nov. and Reticulophragmium naroomaensis sp. nov., are described; this is the first formal record of these genera from Australasia. The age of the host sediment is based on both benthic species and few planktonic foraminifera.

The environment at the time was warm temperate to subtropical at the southwestern extremity of a counter-clockwise Pacific Ocean gyre. The new occurrence extends the record of Palaeogene marine sediments and palaeoenvironments along the eastern margin of Australia and confirms earlier observations that conditions in the marine environment at that time were considerably warmer along the east coast of Australia than those along the southern margin; the biogeographic association was Tethyan. The circulation model may go some way to explaining coeval warmth along the east Antarctic coast.     

泉州蝇埔村“蚵壳厝”牡蛎壳来源初考

为考证泉州“蚵壳厝”牡蛎壳的来源,本文利用了动物学、动物地理学知识对“蚵壳厝”所用的牡蛎壳进行了种类鉴定和分布的分析。结果显示：“蚵壳厝”的牡蛎壳由大量近江牡蛎（CraSS0Strear1Vu一]ar1S）和少量的长牡蛎（C．g1gaS）组成,这两种牡蛎都属巨牡蛎属（CraSS0strea）。动物地理学特点显示,它们都是分布在太平洋一印度洋交汇海域,东非沿海的印度洋西部并没有这些种类的分布。结合前人对海上丝绸之路的研究结果,我们认为泉州“蚵壳厝”牡蛎壳应该是来自于东南亚或南海北部沿海。     

Initial source evaluation of archaeological obsidian from the Kuril Islands of the Russian Far East using portable XRF

Obsidian artifacts recently have been recovered from 18 archaeological sites on eight islands across the Kuril Island archipelago in the North Pacific Ocean, suggesting a wide-ranging distribution of obsidian throughout the island chain over the last 2,500 years. Although there are no geologic sources of obsidian in the Kurils that are known to have been used prehistorically, sources exist in Hokkaido, Japan, and Kamchatka, Russia, the southern and northern geographic regions respectively from which obsidian may have entered the Kuril Islands. This paper reports on the initial sourcing attempt of Kuril Islands obsidian through the analysis of 131 obsidian artifacts. Data from this research were generated through the application of portable XRF technology, and are used to address research questions concerning prehistoric mobility, exchange, and social networking in the Kuril Islands.     

Longitudinal difference in the Sq profiles in the South American region

The average daily variation profiles of the H component at Huancayo on the west coast and Eusébio, Fortaleza, on the east coast in the dip equator region and La Quiaca near the west coast and Vassouras near the east coast in the southern low latitude region of the South American continent indicate that the profiles are broader for the east coast. Thus, distortions in the overhead current systems while passing from one coast to the other are indicated.     

Analysis of Explorers' Records of Aboriginal Landscape Burning in the Kimberley Region of Western Australia

The accounts of explorers and colonists in the Kimberley region of Western Australia were searched to find records of landscape burning by Aborigines. Analyses of these records provide estimates of the spatial and temporal patterns of fire across the region in historic times. The seasonality of fire varied across the region. In northern parts of the Kimberley landscape fire was recorded from May to October with peak levels in June and September. In southern parts of the region there are records of burning as early as February and March, through to August but no records of fire were made in late dry season months. Modern fire regimes were compared with historic by superimposing the routes taken by five explorers over a modern fire history map derived from satellite imagery. Tallies of the number of modern fires that intersect the explorer's daily and monthly route were compared with actual observations of fire made by the explorers in historic times. The results indicate an increase in early dry season fires and the overall frequency of fires across the region in modern times. Explorers' accounts were also examined to derive further information regarding Aboriginal landscape burning in different environments and to distinguish landscape burning from other uses of fire such as smoke signals and cooking fires.     

SOME DATA ON CHANGES IN TRANSPORT ACCESSIBILITY OF EAST SIBERIA AND THE SOVIET FAR EAST IN CONNECTION WITH CONSTRUCTION OF THE BAM

The impact of the Baikal-Amur Mainline on accessibility to resource sites in East Siberia and the Soviet Far East is measured. At the present time, a little more than one-half of the developed southern portion of the region lies within 200 km of the Trans-Siberian. As a result of the construction of the BAM, nearly 75 percent of the area will be within 200 km of the nearest railroad. The gains in distance to the nearest railroad are mapped, and show a maximum gain (of 420–450 km) in an area northeast of the northern tip of Lake Baikal. Although the BAM, because of difficult terrain, is still distinguished by a high coefficient of sinuosity (compared with the great-circle distance), it does represent a gain over the present distance from the Pacific coast to points west of Lake Baikal.     

GPS satellite measurements: ionospheric slab thickness and total electron content

A preliminary analysis was made of ionospheric slab thickness, τ, and total electron content, TEC, for southern Australia using GPS satellite measurements. It was found that at mid-latitudes τ has similar overall diurnal, seasonal and latitudinal variations in the southern hemisphere as in the northern hemisphere. However, there are appreciable differences between τ in the two hemispheres which would justify appropriate modifications to ionospheric models based on northern hemisphere data before being applied confidently to the southern hemisphere. The usefulness of GPS satellites together with ionosondes over a spread of latitudes was demonstrated in determining long-term variations of TEC and τ over a large area. It was concluded that as few as four GPS receivers could provide TEC for the whole of Australia in real-time, though approximately six receivers in convenient locations would be required in practice.     

New species of Late Jurassic Australobuchia (Bivalvia) from the Murihiku Terrane,Port Waikato—Kawhia region,New Zealand

The Early Cretaceous Otway and Strzelecki Groups exposed on the southern coast of Victoria, Australia, have produced a fauna of dinosaurs that lived within the Antarctic Circle. As many as five or six species of hypsilophodontids numerically dominate the collections from there, but the rarer and more fragmentary theropod remains suggest a surprising diversity of carnivorous dinosaurs. A possible surangular and an isolated vertebra have characters considered diagnostic for Late Cretaceous oviraptorosaurs of the Northern Hemisphere. Other fossils suggest the presence of ornithomimosaurs, dromaeosaurids and neoceratopsians, and with the possible oviraptorosaur remains, challenge the widespread assumption that these animals originated on the northern continents.     

Intersections, Networks and the Genesis of Social Complexity on the Nyali Coast of East Africa

This paper examines intersections between different societies occupying the Nyali Coast region of southern Kenya from the late first millennium ad to the mid-second millennium ad. We explore interaction between societies at three scales: between hunter-gatherers and farmers in the coastal hinterland, between the hinterland and the coast and between the coast and the wider Indian Ocean. The patterns indicate that local intersections in the hinterland between hunter-gatherers and farmers went hand-in-hand with both the emergence of larger settlements in the hinterland and on the coast, and participation in a pan-Indian Ocean trade network.     

Pre-Columbian Fishing on the Coast of the Atacama Desert,Northern Chile: An Investigation of Fish Size and Species Distribution Using Otoliths From Camarones Punta Norte and Caleta Vitor

The bountiful marine resources of the northern Chilean coast offset the extreme aridity of the Atacama Desert in pre-Columbian times, underwriting permanent human occupation, and providing the basis for a long tradition of marine subsistence. We analyzed fish otoliths (n = 549) recovered from the sites of Camarones Punta Norte (occupied ca. 7,000–5,000 years ago) and Caleta Vitor (occupied ca. 9,500–300 years ago) to investigate species distribution and changes over time. We also estimated the size of the fish based on relationships between otolith weight and fish total length (TL) obtained from modern samples of the predominant species, Sciaena deliciosa. The estimated size range of S. deliciosa from Caleta Vitor included fish that were significantly larger than those from Camarones Punta Norte, with the maximum TL (970 mm) almost double the modern maximum length documented. The fluctuating abundance of fish species and other marine taxa from Camarones Punta Norte indicates intense but sporadic use of the site over the span of occupation. In contrast, human occupation of the Caleta Vitor estuary is more continuous. Comparisons of the fish assemblages with a nearby contemporaneous site, Quebrada de los Burros in southern Peru, suggest that fishing technologies were similar along this section of the Pacific coast.

Montpellier and Genoa: The dilemma of dominance

During the high and late middle ages, Genoa was a dominant force in Mediterranean commerce. This study examines the relationship between Genoa and the Southern French town of Montpellier in three historical eras: the twelfth century to about 1180; from the 1180s to about 1270; and from 1270 through the mid-fourteenth century. In the first era Genoa, along with Pisa, exercised economic hegemony over the coast of Southern France. In the second period, Montpellier gradually emancipated itself from Genoese commercial control. In the third era interaction between Montpellier and Genoa became increasingly complex because of the growth of French influence in Languedoc. The French monarchy sought to control southern French commerce with a requirement in 1278 that Italian merchants reside in Nimes and trade through Aigues-Mortes, and later in the 1330s with the offer of a transport monopoly over goods from southern France to Genoese admirals Doria and Grimaldi. Montpellier resisted these French efforts, invoking its commercial independence and political allegiance to the Majorcan king. By the mid-fourteenth century Genoese pretensions to commercial dominance over Montpellier were hollow reminders of the past, but the Genoese legacy of business technology remained strong.     

One Colour, (at Least) Two Minerals: A Study of Mulberry Rock Art Pigment and a Mulberry Pigment ‘Quarry’ from the Kimberley,Northern Australia

Distinctive mulberry paintings found in northern Australia, particularly those of the Kimberley region, have been argued to represent some of the oldest surviving rock art on the continent. Significant research efforts continue to focus on resolving the age of these motifs, but comparatively little attention has been given to understanding their physical composition and potential source(s). In a pilot investigation, we conclude that (at least) two mineralogically distinct mulberry pigments occur in Gwion motifs and demonstrate that their major components can be indicatively chemically differentiated, non‐invasively. Characterization of a ‘quarried’ mulberry ochre source demonstrates that these pigments occur locally as natural minerals.     

A Review of Ceramics from Tanzania, Malawi, and Northern Mozambique, with Implications for Swahili Archaeology

Typological approaches to locally produced ceramics have played an important role in the archaeology of Eastern Africa. This paper engages with that history as it contextualizes the ceramic material recently recovered from the region around the site of Mikindani on the southern Tanzanian coast with known traditions from the Kenyan and Tanzanian coast, Malawi, and Mozambique. That comparison reveals the shifting connections and interregional relationships the inhabitants of the Mikindani region forged over the past two millennia with other communities in the Indian Ocean world and the African interior. Mikindani's ceramics are shown to provide important evidence of the deep connections between the region and the African interior to the southwest during the early second millennium, at the expense of connections with coastal Swahili sites further north. This pattern is unusual for a coastal site during the florescence of Swahili society and the typical expansion of Swahili involvement in the Indian Ocean world at that time. The typological comparison of the Mikindani material and other regional traditions thus allows us to consider the strengths and weaknesses of the typological enterprise, in terms of what information is brought to light and what information is obscured.     

The culture history of Madagascar

Madagascar's culture is a unique fusion of elements drawn from the western, northern, and eastern shores of the Indian Ocean, and its past has fascinated many scholars, yet systematic archaeological research is relatively recent on the island. The oldest traces of visitors are from the first century AD. Coastal settlements, with clear evidence of ties to the western Indian Ocean trading network, were established in several places over the next millennium. Important environmental changes of both plant and animal communities are documented over this period, including the extinctions of almost all large animal species. Urban life in Madagascar began with the establishment of the entrepôt of Mahilaka on the northwest coast of the island in the twelfth century. At about the same time, communities with ties to the trade network were established around the island's coasts. From the fourteenth to the sixteenth century, social hierarchies developed in several regions of the island. During the succeeding two centuries, Madagascar saw the development of state polities.     

Distribution of tropospheric ozone in the tropics from satellite and ozonesonde measurements

Measurements from two independent satellite data sets have been used to derive the climatology of the integrated amount of ozone in the troposphere. These data have led to the finding that large amounts of ozone pollution are generated by anthropogenic activity originating from both the industrialized regions of the Northern Hemisphere and from the southern tropical regions of Africa. To verify the existence of this ozone anomaly over this region of the world, an ozonesonde capability has been established at Ascension Island (8 S, 15 W) since July 1990. According to the satellite analyses. Ascension Island is located downwind of the primary source region of this ozone pollution, which likely results from the photochemical oxidation of emissions emanating from the widespread burning of savannas and other biomass in central and southern Africa. These in-situ measurements confirm the existence of large amounts of ozone in the lower atmosphere. These first ozonesonde profiles suggest that much of the ozone generated over Africa during the ‘burning season’ (primarily July-October) reaches Ascension Island. These high levels of ozone in the lower troposphere become much lower by December. Elevated ozone concentrations in the middle troposphere are once again evident in February, which may be the result of biomass burning emissions being transported from western and northern Africa.     

Scientific whaling and how philosophy of science can help break the international deadlock

Despite widespread public interest on the topic of whaling, there is at present relatively little work on how philosophy might contribute to analysis of the status of whaling in international law. When philosophers have looked at the topic of whaling, they have confined their attention to a fairly narrow set of ethical questions, such as whether international law should permit certain forms of traditional indigenous whaling or extend legal rights to whales themselves. However, there is another important issue which has so far been largely neglected by philosophy, even though it is at the forefront of current international legal disputes over the status of whaling: the issue of so-called ‘scientific whaling’. This article considers the international legal dispute between Australia, New Zealand and Japan over the latter’s lethal harvesting of whales in the Southern Ocean, and the recent attempt at resolution by the International Court of Justice. On its face, this required that the Court demarcate ‘scientific’ from ‘unscientific’ activity; however, it effectively baulked at this task. The authors argue that this approach of the Court was unfortunate, and that demarcating science from commerce is not only achievable in philosophy, but might also inform international legal practice. Resolving this issue is important for genuine progress to be made in the current international stand-off over Japanese whaling in the Southern Ocean.     

The youngest non-lepidosirenid lungfish of South America (Dipnoi,latest Paleocene–earliest Eocene,Argentina)

The first lungfish tooth plate from the Las Flores Formation, Chubut, southern Argentina, is described. This is the youngest ceratodontid known from the continent. In Africa, ceratodonts disappeared in the Eocene. Afterwards, they are only known from Australia until their extinction during the Pleistocene. The Las Flores tooth plate also represents the southernmost lungfish known since the Coniacian (early Late Cretaceous).     

21世纪的太平洋——在政治、经济、军事上的重要性评价

太平洋是地球上最大的海洋,在环太平洋沿岸和浩瀚海洋中星罗棋布的岛屿上,分布着40个国家和一些尚未独立的地区,太平洋地区国家陆地面积占世界的46%,人口占世界的40%,但却拥有全球50%以上的GNP和近1/2的世界贸易总额。二次大战以后,太平洋地区的迅速崛起,引起国际舆论的广泛关注。21世纪是太平洋世纪,已日益被国际社会所公认。本文立足于政治军事地理及地缘政治学的基本理论,以21世纪是太平洋世纪的基本结论为出发点,从资源、经济、政治、军事等四个方面对太平洋在21世纪的重要性进行了系统地分析与评价。指出太平洋不仅是人类有待开发的巨大资源宝库和全球经济最富有活力的地区而且是21世纪全球地缘政治中心和地缘战略中心,是世界上各大国和大国集团矛盾的焦点,以及军费增长最快和军备最密集的地区。在今后相当长一段时期内,围绕太平洋地区控制权的争夺竟会日趋激烈。因此21世纪的世界是走向和平还是步入战争,关键取决于环太平洋地区各种战略力量的矛盾与合作。
