## 1 Introduction  
Several publications have analyzed coastal dune systems, both at a global level and within Spain. Different authors have described the types of systems and their main characteristics [1; 2; 3; 4]. Other works have focused on the dynamics and the evolution of these zones, particularly from a geomorphological point of view [5; 6; 7; 8; 9; 10; 11; 12] but also paying attention to anthropic influence in these systems (e.g., References [13; 14; 15; 16]). In this case the research focuses on an integrated analysis using different techniques in the large shifting dune within the Corrubedo Natural Park. This dune is 900 m long and 300 m wide and its maximum height is nearly 20 m. It is a singular formation in the Atlantic coast of the Iberian Peninsula.  
Sedimentary systems are rapidly evolving environments, a fact with major implications both for the population and for economic sectors such as tourism [17]. In this sense and in relation to the potential impacts of global change, research about the evolution of sedimentary systems has become a key issue both for researchers and for society in general. The last few decades have seen an increase in the number of publications analyzing their evolution from multiple perspectives [18; 19; 20]. These variations are associated with technological advances, which have allowed researching this issue with a higher level of detail and accuracy [21; 22; 23].  
The Corrubedo Natural Park is located in Galicia, a region in the NW Iberian Peninsula characterized by a very intricate coastline, with numerous inlets and outlets along more than 2100 km [24]. As the scale of analysis is expanded, the number of the different types of units identified increases. Among these, it is worth highlighting beach-dune systems, frequently associated with small lakes and marshlands, which constitute one of the most vulnerable coastal environments, as well as one of the most sensitive to human impact [25]. The study area could be included within this category. Overall, the Galician coast has been extensively analyzed from different perspectives in recent decades [26; 27; 28; 29; 30].  
The main objective of this study is to analyze the evolution of the Corrubedo large shifting dune over a period of 60 years. This allows us to better understand their dynamics and to prevent the evolution of the dune sector. It aims to expand on the knowledge generated by previous analyses, such as pioneering studies by [PERSON] [31] and [PERSON] [32], in which the authors addressed geomorphological units, as well as by other research studies about the dune system [33], the beach rocks [34] and their evolution or about sections closely located to our study area [35; 36], which have pointed out the influence of ancient topography and described the main characteristics of the system.  
Corrubedo Natural Park as part of Nature 2000 network, the area occupied by the dune appear in the _Plan Director de la Red Natura 2000 de Galicia_ (PDRN) (Decree 37/2014, Xunta de Galicia) with the habitat code 2120, as principal habitat and other dune habitats associated. This zone and the nearby habitats explain the importance of analyze Corrubedo system to improve the management of this area avoid possible problems related to the global change.  
In line with the aforementioned, this work also reflects the importance of key factors, both of natural and human origin, for the existing variations in Corrubedo in order to measure the relevance of these factors for its past dynamics and their role in the present and future of Corrubedo. This is a key element since this study aims to lay the foundations for a more efficient management of the Corrubedo Natural Park.
