“…Within each swath of data, the variables of distance, azimuth, and elevation angles will influence significantly the quality of the data. This variability will translate through to the DBM and subsequent users, if unfamiliar with the original acquisition geometry, may potentially misinterpret such variability as real attributes on the seabed, particularly if the artefacts are at the same scale as the morphologic features of interest [31]. Hughes Clarke [30] warns of the uncertainty that can arise with the ever-increasing ambition of higher-resolution data and cautions that relief close to either the resolution limit or the scale of artefacts increases the risk of over-interpretation by morphological studies.…”

The use of spatial analytical techniques for describing and classifying seafloor terrain has become increasingly widespread in recent years, facilitated by a combination of improved mapping technologies and computer power and the common use of Geographic Information Systems. Considering that the seafloor represents 71% of the surface of our planet, this is an important step towards understanding the Earth in its entirety. Bathymetric mapping systems, spanning a variety of sensors, have now developed to a point where the data they provide are able to capture seabed morphology at multiple scales, opening up the possibility of linking these data to oceanic, geological, and ecological processes. Applications of marine geomorphometry have now moved beyond the simple adoption of techniques developed for terrestrial studies. Whilst some former challenges have been largely resolved, we find new challenges constantly emerging from novel technology and applications. As increasing volumes of bathymetric data are acquired across the entire ocean floor at scales relevant to marine geosciences, resource assessment, and biodiversity evaluation, the scientific community needs to balance the influx of high-resolution data with robust quantitative processing and analysis techniques. This will allow marine geomorphometry to become more widely recognized as a sub-discipline of geomorphometry as well as to begin to tread its own path to meet the specific challenges that are associated with seabed mapping. This special issue brings together a collection of research articles that reflect the types of studies that are helping to chart the course for the future of marine geomorphometry.

La necesidad de disponer de reservas gaso-petrolíferas es imperiosa en el mundo contemporáneo y en el caso de Cuba la situación se acentúa debido a factores externos. Por esta razón numerosas investigaciones son realizadas en el territorio nacional para localizar estructuras favorables donde puedan encontrase acumulaciones de hidrocarburos. El objetivo de esta investigación ha sido estudiar los sedimentos marinos del Golfo de Guacanayabo (Cuba Oriental), los indicios de hidrocarburos en los fondos marinos y el establecimiento de las áreas de mayor interés. Para este estudio se ha combinado la batimetría y la sísmica de reflexión de alta resolución para realizar la cartografía de estructuras anómalas clasificadas como posibles pockmarks y volcanes de lodo (“mud volcanoes”), morfologías generadas por emisiones naturales de hidrocarburos en los fondos marinos. Asimismo, se ha establecido la relación entre emanaciones gaseosas y presencia de gas en los sedimentos del fondo marino y las estructuras profundas y someras en la región. Finalmente, se han establecido las áreas con mayores potenciales a partir de la integración de todos los resultados disponibles. Este estudio permite asegurar las potencialidades del Golfo de Guacanayabo para estudios posteriores en relación con la presencia de hidrocarburos en el subsuelo.
