Rugulopteryx okamurae is a species of brown macroalgae belonging to the Dictyotaceae family and native to the north-western Pacific. As an Invasive Alien Species (IAS), it was first detected in the Strait of Gibraltar in 2015. Since then, R. okamurae has been spreading rapidly through the submerged euphotic zone, colonizing from 0 to 50 m depth and...

Use of Earth Observation and remote sensing techniques for monitoring the marine invasive alien macrophyte R. okamurae in Tarifa (Spain). Use of multispectral (Landsat-8 and Sentinel-2) and hyperspectral (UAV) data and machine learning methods for classification mapping.

Las Floraciones Algales Nocivas (FANs) son eventos comunes en las zonas costeras y aguas interiores, producidas por el aporte de nutrientes al agua (N y P) y las altas temperaturas (Gilbert y Burkholder, 2006), y en las últimas décadas están sufriendo un incremento en su frecuencia y extensión afectando a la economía local (Gobler, 2020). Suponen u...

During recent years, several eutrophication processes and subsequent environmental cri-ses have occurred in Mar Menor, the largest hypersaline coastal lagoon in the Western Mediterra-nean Sea. In this study, the Landsat-8 and Sentinel-2 satellites are jointly used to examine the evolution of the main water quality descriptors during the latest ecol...

Estuarine degradation is a major concern worldwide, and is rapidly increasing due to anthropogenic pressures. The Mediterranean Guadiaro estuary, located in San Roque (Cadiz, Spain), is an example of a highly modified estuary, showing severe negative effects of eutrophication episodes and beach erosion. The migration of its river mouth sand spit ca...

This paper analyses the coastal changes between the harbours of Castellón and Sagunto from 1956 until the present day. Images of the coastline in different years have been obtained from various sources (aerial photographs, satellite images, orthophotos) in order to estimate and compare the rates of shoreline advance and retreat. The results indicat...

Remote sensing techniques are becoming a key tool for coastal mapping in terms of resolution, effectiveness and cost reduction. Sentinel-2A/B twin satellites are part of the free and open policy programme available since 2015, but atmospheric corrections or cloud cover are still challenges to face. In order to process this data, cloud computing pla...

Nowadays massive tourism is being a risk for littoral and marine conservation. This project tries to bring GIS closer to citizens with several solutions. Using Esri technology (ArcGIS) 12 apps have been developed, going from natural and cultural tourism planification to ecocartographic apps trying to mitigate the damage caused by anchoring on Posi...

En el siguiente documento se muestran diversas soluciones GIS reproducibles para cualquier municipio costero. Estas se encuentran dirigidas a la mejora de la gestión datos a nivel interno, a la filosofía instaurada de datos abiertos y a la movilización de un turismo cultural, natural y sostenible teniendo en cuenta su marcada estacionalidad. Todas...

Serra d'Irta (Castellón, Spain) was declared marine reserve of fishing interest (MRFI) in 2003 with the objective of favouring the regeneration of marine resources. This work presents the results obtained in the monitoring studies realized in this reserve during summer of 2017 using different marine macrophyte indexes. The aim of this study was to...

Marine environmental consultancies face a challenge in front of the great volume of information generated day by day, which has to be managed to achieve a correct traceability. Currently, after having conducted a survey of consultancies and Spanish marine entities, 88% of consultants (n=25) believe there is really a great lack in the data organizat...
