摘要

比斯开湾是一个结构复杂的地区,生物多样性和生产力都很高,底栖生物栖息地种类繁多。遗憾的是,目前有关深海生态系统的科学知识十分有限。我们的调查对深海生态系统关键方面的现有知识进行了更新,并确定了研究重点,以制定研究路线图,支持可持续管理,包括保护和养护比斯开湾的深海生态系统。为此,首先对该地区开展的项目、调查和研究进行了修订,最终确定了 62 份公开的科学文 献。其次,开展了网上调查,收到了来自 9 个国家 24 个研究机构的 51 份答复。最后,39 名科学家参加了研讨会,确定并讨论了比斯开湾深海研究的前进方向。结果表明,45%的受访者对海底生境以及脆弱和敏感生境/物种的了解较好或非常好,而对深海水层生境的了解有限。近 75% 的科学家同意深海过程会影响较浅区域。资金(71%)和研究船只的可用性(57%)被认为是限制深海研究的最大因素。50%以上的科学家认为人类活动和压力会造成短期或中期威胁,40%以上的受访者认为没有数据或数据有限,无法评估环境状况。关于气候变化,55%的科学家部分或完全同意存在气候变化影响的证据,但 47%的科学家完全或部分认为气候变化监测不足以评估最终的变化和影响。大多数受访者(63%)认为,目前的海洋保护区网络没有适当体现深海生态系统。就未来需求而言,最常提到的是制定监测战略以降低成本和保证最佳设计、数据共享和加强跨国合作。最后,提出了一个路线图建议,以填补知识空白,更好地了解比斯开湾深海的生态系统过程。

Research priorities and roadmap for deep-sea ecology in the Bay of Biscay (Northeast Atlantic)

The Bay of Biscay is a structurally complex region, exhibiting high biodiversity and productivity and hosting a wide variety of benthic habitats. Unfortunately, current scientific knowledge of deep-sea ecosystems is limited. Our investigation provides an updated vision of the existing knowledge on key aspects of the deep-sea ecosystem and identifies research priorities for the definition of a research roadmap in support of sustainable management, including the protection and conservation of deep-sea ecosystem of the Bay of Biscay. To achieve this, firstly a revision of projects, surveys and studies conducted in the region, was carried out resulting in the identification of 62 publicly available scientific documents. Secondly, an online survey was carried out, receiving 51 responses from 24 research institutions in 9 countries. Finally, a workshop was attended by 39 scientists to identify and discuss ways forward on deep-sea research in the Bay of Biscay. Results indicate that knowledge of benthic habitats, and vulnerable and sensitive habitats/species is good or very good for 45% of the respondents, while limited knowledge was reported for deep pelagic habitats. Almost 75% of the scientists agreed that deep-sea processes affect shallower areas. Funding (71%) and research vessel availability (57%) were considered the most constraining aspects limiting deep-sea research. More than 50% of the scientists perceived a short- or medium-term threat from human activities and pressures, while over than 40% of the respondents considered that there are no, or limited, data available to assess the environmental status. Regarding climate change, 55% of scientists partially or fully agreed with the existence of evidence of climate change effects, but 47% of them totally or partially considered that climate change monitoring is insufficient to assess eventual changes and effects. Most respondents (63%) considered that deep-sea ecosystems are not properly represented in the current Marine Protected Areas network. In terms of future needs, the development of monitoring strategies to reduce costs and guarantee an optimal design, data sharing and an increase in transnational collaboration are most cited. Finally, a proposal for a roadmap to fill in knowledge gaps for a better understating of the ecosystem processes of the deep sea of the Bay of Biscay is delivered.

期刊介绍: Deep-Sea Research Part I: Oceanographic Research Papers is devoted to the publication of the results of original scientific research, including theoretical work of evident oceanographic applicability; and the solution of instrumental or methodological problems with evidence of successful use. The journal is distinguished by its interdisciplinary nature and its breadth, covering the geological, physical, chemical and biological aspects of the ocean and its boundaries with the sea floor and the atmosphere. In addition to regular "Research Papers" and "Instruments and Methods" papers, briefer communications may be published as "Notes". Supplemental matter, such as extensive data tables or graphs and multimedia content, may be published as electronic appendices.
