The perceived neglect of the ocean to state and industry actors has seen frontier rhetoric emerge as it is rendered visible under the Blue Economy agenda. By framing the marine scape as underutilised, capitalist expansion is being legitimised. Drawing on the case of Namibia, I argue that the afterlives of colonialism and apartheid are being repurposed to present the ocean as a Blue Economy opportunity. The physical disconnection of citizens from the marine scape, and the dominance of fishing and mining industries, has been used by state and development actors to present it as empty of socio-cultural relations. However, to declare Namibia’s coasts and ocean as forgotten unless articulated through capital is to conceal that they have been labelled “no-go” zones. I argue that, by considering exclusions and looking beyond proximity in discussions of equity and representation, the marine scape is articulated by civil society, to elucidate forms of resistance. 相似文献

This intervention develops arguments in our book Capitalism and the Sea on the complex temporalities attached to capitalism's intense and peculiar relationship to the global ocean. Technological innovations like the steamship or containerisation plainly transformed the pace and intensity of maritime commerce, and aspects of the global economy. We take this further to argue that the very origins and periodisation of capitalism are connected to the global ocean; as will be our futures, given the unpredictable implications of the oceans acting as the biosphere's ‘heat sink’. We consider several stylised expressions of time at sea: deep-time, logistical-time, life-time, and revolutionary time suggesting that the ocean world as a geographical space articulates these in distinctive and contradictory ways. 相似文献

Although generally distinct from continental environments, and therefore of interest in their own right, island environments have been generally misunderstood, misinterpreted, and mismanaged. The main reason is that they have been interpreted for management purposes largely by continent‐trained observers. An example of views towards island size is given. It is argued that the pejorative label ‘small’ should no longer be used to characterise islands. The ways in which island environments have been impacted by humans and their commensals is given. Questions of the sustainable development of island environments are also considered, including for whom these should be sustainable, how extraneous threats like sea‐level rise are best incorporated into such plans, and what threats are posed to the rest of the world by mega‐tsunami from certain island environments. Island environments are best managed by persons who understand their distinct character and who are committed to their future. 相似文献

The simulation of Sea-ice in a coarse resolution ocean general circulation model is examined in Hudson Bay and surrounding waters. Sea-ice distribution and duration compared well to climatological values, although ice thickness is undersimulated as it is in other modelling work. In Hudson Bay ice thickness variation was dominated by the atmospheric forcing as shown by the symmetric response of ice thickness to warming and cooling scenarios. Below ice heat fluxes play a more significant role in Foxe Basin and Baffin Bay where they mitigate air-ice heat loss by as much as 40 percent, thus limiting ice thickness and duration. Below ice heat flux reduces by 23 percent for the region of study (Hudson Bay, Foxe Basin, Baffin Bay, and Labrador Sea) for a global 3°C cooling and increases by 9 percent for a 3°C global warming. This asymmetric response is attributed to the ocean's asymmetric response to warming and cooling scenarios. In so much as Hudson Bay is dominated by atmospheric forcing rather than under ice heat as these results indicate, coarse resolution models may be useful in assessing the impact of change. However the necessary reconfiguration of the model grid render results from Foxe Basin and Hudson Strait less credible. On étudie la simulation de glace marine dans un modèle de circulation océanique générale à faible résolution dans la baie d'Hudson et dans les eaux avoisinantes. La distribution et la durée de la glace marine correspondent bien aux valeurs climatologiques, bien que l'épaisseur de la glace soit sous-simulée comme c'est le cas dans d'autres travaux de modélisation. Dans la baie d'Hudson, la variation de l'epaisseur de la glace est dominée par le forçage atmosphérique, comme on peut le voir d'après la réponse symétrique de l'épaisseur de la glace suivant les scénarios de réchauffement et de refroidissement. Les flux de chaleur sous la glace jouent un rôle plus important dans le bassin de Foxe et la baie Baffin, où ils permettent une réduction des pertes de chaleur air-glace allant jusqu'à 40 pour cent, limitant ainsi l'épaisseur de la glace et la durée. Le flux de chaleur sous la glace diminue de 23 pour cent dans la région étudiée (baie d'Hudson, bassin de Foxe, baie Baffin et mer du Labrador) pour un refroidissement global de 3C et augmente de 9 pour cent pour un réchauffement global de 3C. On attribue cette réponse asymétrique à la réponse asymétrique de l'océan aux scénarios de refroidissement et de réchauffement. Dans la mesure où, comme l'indiquent ces résultats, la baie d'Hudson est dominée par le forçage atmosphérique plutôt que par la chaleur sous la glace, des modèles à faible résolution peuvent être utiles pour évaluer l'impact des changements. Cependant, la reconfiguration nécessaire de la grille du modèle atténue la crédibilité des résultats obtenus dans le Bassin de Foxe et le détroit d'Hudson. 相似文献

21世纪的"海洋破碎带" 总被引：2，自引：0，他引：2
本简析了海洋的争夺史,在此基础上提出了本的中心议题—21世纪的“海洋破碎带”。探析了“海洋破碎带”形成的七大因素,即：①海洋霸权主义对海洋国际贸易通道的争夺;②国际间对海洋国土的争夺;③海洋生物资源的争夺;④海洋矿产资源的争夺;⑤南极大陆的争夺;⑥海军军备竞赛;⑦海缘政治形势日益恶化。阐释了21纪“海洋破碎带”分布的海域。最后指出,中国不仅是一个陆地国家,也是一个海洋国家,中国的海上安全已近底线。为此,中国必须树立新的海洋观念,建立强大的海军,保卫国家的每一寸海洋国土。 相似文献

传统书画作品中存在有大量模糊不清的印章,对此类印章尚没有很好的手段进行提取和鉴别。为解决这一问题,本工作采用一种用高光谱图像系统采集书画中模糊印章的光谱-图像信息,采用最小噪声分离变换(MNF)处理光谱图像数据,提升了模糊印章的可辨识度。结果表明,采用该方法能够有效的将模糊印章的信息提取出来,有利于印章的鉴别和研究,为书画的文物价值和真伪鉴别的研究提供了科学有效的手段。 相似文献

Australia and Indonesia are two vastly different countries that share a common sea border in the Timor and Arafura Seas. Yet economically, culturally and diplomatically, Australia and Indonesia have been moving much closer together over the last 20 years. In March 1997, the final portion of the seabed border was finally delineated, shortly before the onset of the serious economic crisis. This paper focuses on the changing political and economic relations between the two countries and links this with a discussion of border issues, specifically UNCLOS III, fish and hydrocarbon resources, the Timor Gap Zone of Cooperation and the still unresolved East Timor question. 相似文献

ABSTRACTEpeli Hau‘ofa's definition of the Pacific as a ‘sea of islands' should be extended to the Indigenous history of the North Pacific Ocean. Several themes prominent in the history of Oceania – such as humans' orientation towards the ocean, the complex ways in which European and Indigenous histories mixed in the colonial era, and the notion of vast, interconnected spaces – apply to North Pacific history as well. This essay looks at the ways in which the history of the Russian Far East and Alaska could be written as Pacific history and integrated into histories of Oceania. Such an integration would provide numerous benefits for historians and activists in the North Pacific. Some important topics in the history of these northern regions, such as the interdependence of human and natural systems, could also enrich historiography in Oceania. 相似文献
