The North Sea — A shelf Sea in the Anthropocene
Journal of Marine Systems, 2015Co-Authors: Kay-christian Emeis, Justus Van Beusekom, Ulrich Callies, Ralf Ebinghaus, Andreas Kannen, Gerd Kraus, Ingrid Kröncke, Hermann Lenhart, Ina Lorkowski, Volker MatthiasAbstract:Abstract Global and regional change clearly affects the structure and functioning of ecosystems in shelf Seas. However, complex interactions within the shelf Seas hinder the identification and unambiguous attribution of observed changes to drivers. These include variability in the climate system, in ocean dynamics, in biogeochemistry, and in shelf Sea Resource exploitation in the widest sense by societies. Observational time series are commonly too short, and resolution, integration time, and complexity of models are often insufficient to unravel natural variability from anthropogenic perturbation. The North Sea is a shelf Sea of the North Atlantic and is impacted by virtually all global and regional developments. Natural variability (from interannual to multidecadal time scales) as response to forcing in the North Atlantic is overlain by global trends (Sea level, temperature, acidification) and alternating phases of direct human impacts and attempts to remedy those. Human intervention started some 1000 years ago (diking and associated loss of wetlands), expanded to near-coastal parts in the industrial revolution of the mid-19th century (river management, waste disposal in rivers), and greatly accelerated in the mid-1950s (eutrophication, pollution, fisheries). The North Sea is now a heavily regulated shelf Sea, yet societal goals (good environmental status versus increased uses), demands for benefits and policies diverge increasingly. Likely, the southern North Sea will be re-zoned as riparian countries dedicate increasing Sea space for offshore wind energy generation — with uncertain consequences for the system's environmental status. We review available observational and model data (predominantly from the southeastern North Sea region) to identify and describe effects of natural variability, of secular changes, and of human impacts on the North Sea ecosystem, and outline developments in the next decades in response to environmental legislation, and in response to increased use of shelf Sea space.

ReSearch on Level Relationships and Spatial Structure in Area of Western Liaoning
Economic Geography, 2013Co-Authors: Wang Shi-junAbstract:The western Liaoning,as the reSearch object,is divided into 21 central places based on administrative units which above country level in this study.The reSearch will use analysis methods including principal component analysis and comprehensive marking method to divide the study area into 4 grades and to analyze the spatial structure of the study area.The spatial structure of western Liaoning has characters as follow:(1) Grade one and grade four forms zonal distribution;(2) Grade two have a compact structure and locate by the coast and in the inland area;(3) Grade three link high-grade ones and bottom-grade ones as connections.The characters above are controlled by comprehensive factors of many aspects.Micro policies,cleavage action by the Bohai Sea,Resource and economic connection with other regions,such as the Bohai Rim,are the most important function factors to form the spatial structure in western Liaoning.To construct the central places system as a more reasonable and more effective spatial structure,attention should be paid to coordinate the Resource distribution and industrial layout to void unnecessary internal competition.Besides,the western Liaoning area would be better participate in regional cooperation more actively.Furthermore,to exert central places' merit will give a great help,such as to improve the central function of high-level central places and to stimulate contribution of bottom-level central places.

Natural Capital and Exploitation of the Deep Ocean - Climate change cumulative impacts on deep-Sea ecosystems
Natural Capital and Exploitation of the Deep Ocean, 2020Co-Authors: Nadine Le Bris, Lisa A. LevinAbstract:Climate models report that the environmental changes resulting from excess CO2 and heat absorption by the ocean already reach many deep-ocean margins, basins, and Seas. Decadal monitoring programmes have confirmed significant warming and deoxygenation trends down to the abyss, which combine with CO2-enriched, more corrosive conditions. Although the resolution of current models does not account for the typical mesoscale Seafloor heterogeneity, cumulative impacts on biodiversity and productivity hotpots are anticipated. The growing interest in deep-Sea Resource exploitation has shed light on the lack of knowledge about current climate-driven disturbance and potential cumulative threats at great depth. Assessing the sensitivity of deep-Sea ecosystems to temperature increase combined with oxygen and Resource decline is emerging as a growing challenge. The natural patchiness of deep-Seafloor habitats and associated deep-Sea diversity patterns inform about environmental constraints over space, but the temporal dynamics of these systems is not well known. Experimental studies are required to assess the physiological limits and explore the adaptation and acclimation potential of foundation species exposed to various forms of abiotic stress. The case of cold-water corals is particularly illustrative of the potential synergistic effects of climate stressors, including warming, acidification, deoxygation, and reduced food availability. Addressing ecosystem vulnerability also requires dedicated monitoring efforts to identify the current and future drivers of climate-change impacts on deep-Sea habitats. United Nations policy objectives for protected high-Sea biodiversity and healthy oceans and Seas drive the momentum towards better climate-change forecasting over the ocean-depth range and related integrated observing strategies.

Climate change considerations are fundamental to management of deep‐Sea Resource extraction
Global change biology, 2020Co-Authors: Lisa A. Levin, William Wl Cheung, Chih-lin Wei, Daniel C. Dunn, Diva J. Amon, Oliver S. Ashford, Ana Colaço, Carlos Dominguez-carrió, Elva Escobar, Harriet Harden-daviesAbstract:Climate change manifestation in the ocean, through warming, oxygen loss, increasing acidification, and changing particulate organic carbon flux (one metric of altered food supply), is projected to affect most deep-ocean ecosystems concomitantly with increasing direct human disturbance. Climate drivers will alter deep-Sea biodiversity and associated ecosystem services, and may interact with disturbance from Resource extraction activities or even climate geoengineering. We suggest that to ensure the effective management of increasing use of the deep ocean (e.g., for bottom fishing, oil and gas extraction, and deep-Seabed mining), environmental management and developing regulations must consider climate change. Strategic planning, impact assessment and monitoring, spatial management, application of the precautionary approach, and full-cost accounting of extraction activities should embrace climate consciousness. Coupled climate and biological modeling approaches applied in the water and on the Seafloor can help accomplish this goal. For example, Earth-System Model projections of climate-change parameters at the Seafloor reveal heterogeneity in projected climate hazard and time of emergence (beyond natural variability) in regions targeted for deep-Seabed mining. Models that combine climate-induced changes in ocean circulation with particle tracking predict altered transport of early life stages (larvae) under climate change. Habitat suitability models can help assess the consequences of altered larval dispersal, predict climate refugia, and identify vulnerable regions for multiple species under climate change. Engaging the deep observing community can support the necessary data provisioning to mainstream climate into the development of environmental management plans. To illustrate this approach, we focus on deep-Seabed mining and the International Seabed Authority, whose mandates include regulation of all mineral-related activities in international waters and protecting the marine environment from the harmful effects of mining. However, achieving deep-ocean sustainability under the UN Sustainable Development Goals will require integration of climate consideration across all policy sectors.
