Abstract

The shallow-water hydrothermal vents in Paleochori Bay (Milos Island, Greece) are among the most active and well-known volcanic systems in the world. Despite almost three decades of research, however, their spatial and temporal variability remains poorly understood because of the dearth of reliable and repeated measurements. Diachronic analysis on GIS (Geographical Information System) platform allowed comparing seafloor maps of the area produced in the 1990s and 2010s to assess spatial stability or change in the main hydrothermal features (largest microbial mats). Notwithstanding differences between methods and observers, the comparison provided suggestive evidence that in two decades the main hydrothermal features of Paleochori Bay have shifted from their original location and changed in both extent and composition. Our study is the first of this type on shallow-water hydrothermal vents; further studies in other regions and repeated mapping in Paleochori Bay will be needed to understand the dynamics of these systems, both for research and management.

浅水热液喷口稳定吗？相隔20年的古克里奥里湾（希腊米洛斯）地图的比较

希腊米洛斯岛（Milos Island, Greece）的古霍里湾（palechori Bay）的浅水热液喷口是世界上最活跃、最著名的火山系统之一。然而，尽管进行了近三十年的研究，但由于缺乏可靠和重复的测量，对它们的时空变异性仍然知之甚少。在GIS（地理信息系统）平台上进行历时分析，可以比较20世纪90年代和2010年代制作的该地区海底地图，以评估主要热液特征（最大的微生物垫）的空间稳定性或变化。尽管方法和观测者之间存在差异，但比较提供了暗含的证据，表明近20年来古chori湾的主要热液特征已经从其原始位置转移，范围和组成都发生了变化。我们对浅水热液喷口的这类研究尚属首次；为了研究和管理，需要在其他地区进行进一步研究，并在古古里湾进行重复测绘，以了解这些系统的动态。

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
