Cala Millor Coastal Station Endurance Line

Systematic and sustained high quality measurements of nearshore waves and beach morphology are crucial to unravel the effects of global warming on sandy coasts and thus be able to assess the validity of sediment transport numerical models. Such measurements are also key to understanding the morphodynamic processes that determine how the beach evolves. In 2011 a comprehensive beach monitoring program, the first in the Mediterranean Sea, started at Cala Millor Beach on the island of Mallorca (Spain). The aim was to provide long-term datasets of near-shore morphodynamics in a carbonate sandy micro-tidal and semi-embayed beach fronted by a Posidonia oceanica seagrass meadow. The dataset includes topobathymetries, shoreline positions obtained from video cameras, meteorological parameters from a weather station, currents, as well as waves and sea level from ADCP measurements and sediment size. This free and unrestricted archived dataset can be used to support the modelling of erosion-deposition patterns, calibrate beach evolution models, and as a result to propose adaptation and mitigation actions under different global change scenarios.

系统且持续的高质量近岸波浪与海滩地貌测量，对于厘清全球变暖对砂质海岸的影响、进而评估泥沙输运数值模型的有效性至关重要。此类测量亦是解析控制海滩演化过程的地貌动力学机制的关键所在。2011年，西班牙马略卡岛的卡拉米洛尔海滩（Cala Millor Beach）启动了地中海地区首个综合性海滩监测项目。该项目旨在为一处以海神草（Posidonia oceanica）海草床为岸界的碳酸盐质砂质微潮差半封闭海湾型海滩，提供近岸地貌动力学的长期数据集。本数据集涵盖地形测深数据、摄像机采集的岸线位置数据、气象站获取的气象参数、海流数据，以及通过ADCP（声学多普勒流速剖面仪）测量得到的波浪与海平面数据，还有沉积物粒径数据。本免费开放的存档数据集可用于支撑海岸冲淤格局模拟、校准海滩演化模型，进而助力提出不同全球变化情景下的海岸适应与减缓措施。
