“…Furthermore, these episodes exert a significant influence on sea levels, with fluctuations that can reach up to ±30 cm, intensifying changes in coastal morphology (Martínez et al, 2018). However, it is important to emphasize the need for local measurements, as there is evidence that the figures obtained at local stations can differ significantly from global observations, as noted in the study by Jigena-Antelo et al (2023). This study found that IPCC estimates for the period between 2006 and 2015 indicated a sea-level rise of 3.60 mm/year.…”

“…In this study, it was concluded that for every unit change in the standardized Niño3 index, there is an estimated alteration in MSL of approximately 30.47 mm. Subsequent research, such as the study conducted by Jigena-Antelo et al (2023), which utilized data from local monitoring stations, revealed significant increases in sea level during exceptional El Niño episodes. This was particularly evident in January 1983 and December 1997, with deviations of 0.38, 0.34, and 0.31 m compared to monthly averages.…”

Coastal zones in Latin America support a significant regional population and are vital for providing essential ecosystem services that underpin crucial socio economic activities. However, these zones face pressing challenges, with coastal erosion being a prominent concern. Coastal erosion not only jeopardizes coastal stability but also leads to occasional loss of natural habitats. This is particularly worrisome for sandy beaches due to the consistent shoreline retreat in specific regions. Short term adverse effects of coastal erosion are often attributed to human activities. Nonetheless, the influence of hydrodynamic processes, intensified by extreme events, is gaining prominence. This is due to the combined impact of tides, waves, currents, and other factors, resulting in accelerated shoreline retreat and significant losses of infrastructure and beach areas across Latin America. This article conducts a comprehensive analysis of case studies in Latin America related to coastal erosion due to hydrodynamic processes. Employing a systematic review approach, data is extracted from Scopus and Web of Science databases. From an initial dataset of 701 records, 62 records meet strict eligibility criteria. Case studies present evidence of how hydrodynamic processes interact with various factors, encompassing oceanic climatic conditions, atmospheric climatic conditions, anthropogenic influences, geomorphological and bathymetric characteristics, geological and tectonic factors, and climate change related aspects. These interactions have an immediate and significant impact on sandy beaches, emphasizing the necessity of comprehensively addressing these linkages when analyzing shoreline changes. This approach aids in identifying key erosion mechanisms and developing effective mitigation measures. Furthermore, the article provides a concise overview of data sources, tools, and methodologies identified in the case studies, spanning from field investigations to the utilization of geographic information systems and numerical models. Underscores the crucial role of international academic collaboration in coastal erosion research, facilitating the adoption of innovative methodologies from other regions, potentially offering a more comprehensive perspective in the formulation of mitigation and adaptation strategies. Finally, potential areas for future research in Latin America are explored, including the assessment of extreme event variability and its impacts on local and regional hydrodynamic processes. This aspect holds critical importance in steering future research towards scenarios that encompass economic and social considerations.

“…Tidal records are one of the most comprehensive and reliable oceanic time series in the world. Their independent use and correlation with other parameters provides valuable information about the oceanic variability on seasonal and yearly scales, allowing the monitoring of their impact on continental margins [22].…”

“…In some developing countries there are insufficient long-term sea level records to allow comprehensive and predictive studies to be undertaken. Especially in areas of difficult access, data are only taken during the summer season, or for specific projects, and, generally, the data are taken over a year or less duration [22]. Obviously, this methodology cannot be applied in these cases.…”

This article provides a general methodology for calculating the retreat of the coastline and the volume of sand necessary to renourish a beach due to sea level rise (SLR) in the medium-long term. An example is presented, Victoria Beach, and a projection is made for the years 2030, 2040, 2050, and 2100. The results obtained take into account global sea level rise (GSLR), which is worldwide, and local sea level rise (LSLR), which considers climate variability and vertical land movements. Regarding GSLR, data were provided by the projections from IPCC (Intergovernmental Panel on Climate Change) scenarios and empirical models, such as Rahmstorf and Pfeffer. The LSLR data came from the tide gauge station located in Cadiz. Finally, the results obtained showed that global warming impacts erosive effects and the subsequent volume of sand required to renourish beaches. The total sea level rise (TSLR) projections indicated for Victoria Beach are relatively higher than the GSLR projections. Even in the best IPCC scenario (RCP 2.6), Victoria Beach presents a significant erosion of 52 m, requiring a volume of sand of 1.0 Mm3 to supply renourishment.

“…The study of submarine, coastal, and insular areas in the world has been widely developed in recent decades [1][2][3][4][5]. This is particularly thanks to the development of technologies and methods in the acoustic, geodesic, geophysical, and remote sensing fields, as well as the improvement in geospatial data management [6][7][8][9][10][11][12]. The incorporation of new methods for the exploration of deep environments has allowed researchers to detect and map shallow gas accumulations in marine deposits [13][14][15].…”

High-resolution seismic analysis and bathymetry data, used in the Offshore Sinú Fold Belt (OSFB), have revealed seabed and sub-surface anomalies, which were probably caused by the presence of shallow gas within the sedimentary records. Shallow gas is widely detected by the frequent presence of anomalous acoustic reflections including acoustic blanking, enhanced reflections, acoustic plumes, pockmarks, and dome structures. More than 30 anomalies that occur within a subsurface depth of ~65 m were acoustically detected within an area of 1000 km2 on the continental shelf and upper continental slope, in water depths ranging from −20 to −1300 m. Moreover, a map with the spatial distribution of the gas occurrences is shown. A close relationship between the locally elevated seabed (dome structures), pockmarks, and acoustic blanking was found. Most of the active pockmarks may be closely related to the submarine path of the Uramita Fault, indicating that the gas occurrences are controlled by active faulting. The shallow gas occurrence was confirmed by the generation of authigenic carbonate and the occurrence of chemosymbiotic biological communities sampled in the area. Although there is an admixture of biogenic gas, it is believed that many of the features observed relate to thermogenic gas. The identification of these anomalies represents a useful basis for an assessment of marine geohazards and can serve as a hydrocarbon exploration tool.
