About this Research Topic
Coastal realms are among the most dynamic places on Earth, in terms of social and economic development and natural catastrophes, and home to 40% of the population. In the venue of modern climate change, new techniques are needed to assess the impact of variations in relative sea level on coastal landscapes at a broad range of spatial and temporal scales. Because relative sea level includes both geodynamic and climatic components, it is necessary to integrate past and modern observables with new modeling techniques in order to envisage future scenarios and estimate hazards and risks.
New concepts evolve, aided by new modeling strategies, supported by field observations and benefitted by the recent technological advances. These include the development of high-resolution topographic and bathymetric digital terrain models and subsurface geophysical imaging at increasingly low costs. The integration of models and metrics opens new scenarios for quantitatively characterising landscapes and their change through time, gaining insight on the underlying physical processes responsible for shaping coastal landscapes, isolating the respective roles of climatic and tectonic forcing and exploring potential feedbacks.
We welcome studies of coastal landscapes related to:
1) Applications of high-resolution topographic and bathymetric models, or time series analysis, to constrain the morphology and metrics of fossil and/or modern coastal landscapes, including sea-level markers (e.g. marine terraces, coral reefs, strand lines, notches);
2) Studies dealing with Quaternary geochronology to quantify rates associated with the generation and degradation of coastal landscapes;
3) Studies using numerical models to constraint coastal processes at different spatial and temporal scales;
4) Application of subsurface imaging techniques (e.g. Ground Penetrating Radar) to unravel sea-level histories.
There is no geographical restriction: research objectives may range from local to global case studies, conceptual and theoretical investigations, methodological approaches, or may unify all aspects.
