“…de limos (principalmente en los núcleos EU-VI y EU-VII, recolectados en sitios cercanos a la marisma) indican la posibilidad de una mayor evaporación (Cuellar-Martinez et al, 2017) o la influencia de una paulatina transgresión marina, donde los sedimentos marinos son transportados desde el mar, durante las inundaciones (Ruiz-Fernández et al, 2018a).…”

Los manglares, junto con los pastizales marinos y las marismas, se encuentran entre los ecosistemas costeros conocidos como ecosistemas de carbono azul. Estos ecosistemas son relevantes para la mitigación del calentamiento global debido a que son capaces de secuestrar importantes cantidades de CO2 para producción de biomasa, así como de almacenar materia orgánica en sus sedimentos durante muy largo plazo. Se presentan los resultados de la evaluación temporal de los flujos (g m-2 año-1) e inventarios (Mg ha-1) de carbono orgánico (Corg) en manglares asociados a la laguna costera Estero de Urías (Mazatlán, Sinaloa), realizado a partir del análisis de núcleos sedimentarios. La estrategia de trabajo incluyó la caracterización geoquímica de los sedimentos mediante el análisis de composición elemental por espectrometría de fluorescencia de rayos-X para evaluar cambios en el origen de los sedimentos (terrígeno o marino), la determinación de la distribución de tamaño de grano para evaluar cambios en la hidrodinámica de los sitios de estudio, y la cuantificación de las concentraciones de Corg mediante un analizador elemental. Por último, se presenta una estimación del costo económico de los impactos de las emisiones potenciales de CO2 como consecuencia de la oxidación del Corg, debido a las potenciales perturbaciones de los sitios de estudio. Esta información representa una componente más de los beneficios económicos de la preservación de los ecosistemas de manglar en México.

“…First, the low temporal resolution of the profile, principally in the bottom sections (mean resolution of 14 years in the 3–11 cm segment); second, the uncertainty of hurricane impacts on sedimentation, which are poorly constrained by modeled trajectories. Third, the coastline features such as water depth, mangroves, and dunes that modify the effects of hurricanes on sediments (Cuellar-Martinez et al., 2017 and references therein).…”

Coastal accretion and sea-level rise in the Cuban Archipelago obtained from sedimentary records

Sea-level rise (SLR) is one of the most pervasive consequences of global warming, and the Cuban Archipelago is threatened by current and future SLR. In order to support adaptation plans, it is essential to have reliable information about sea-level change during the last decades at the local scale, particularly in the most vulnerable regions. Here, we use sedimentary records to evaluate coastal accretion and to estimate the relative sea-level rise (RSLR) in two vulnerable coastal sites in central Cuba: Cayo Santa María (CSM) and Península de Ancón (PA). Both sites showed sediment sections with a continuous record of sediment accretion as a result of relative SLR and tropical storms. The sedimentary process was different between CSM and PA owing to differences in geomorphology and primary mineral composition. Sedimentary records also showed recent impacts of anthropogenic activities, likely increasing the vulnerability of the shoreline to SLR. The estimated RSLR values agreed with tidal gauge records, although they spanned a much longer time period (CSM: 0.5 ± 0.1 mm a−1, span of 38 years; PA: 1.5 ± 0.3 mm a−1, span of 92 years). Our results confirm that this methodology may be used to estimate the RSLR in places where data by instrumental records do not exist.

“…This isotopic dating is done either by sediments from surface facies (e.g. Abrantes et al, 2008;Cuellar-Martinez et al, 2017), or by the organic elements present in the core (e.g. Bregy et al, 2018;Feal-Pérez et al, 2014).…”

This paper presents the benefits of multiplying environmental indicators to better understand the impacts of past storm events on the environment. It aims to describe the methodological approaches used to reconstruct past extreme events from washover deposits, at the three main temporal scales used in scientific bibliography: i) the long timescale (Holocene, since 12 000 years BP), ii) the meso timescale (for the last millenary) and iii) the short timescale (Anthropocene, for the last centuries). This methodology is based on a "multiproxy" analysis using sedimentology, geochemistry and various methods of isotope dating. Linking these methods with other disciplines such as history, archaeology and meteorology leads us to confirm with great certainty the existence of these extreme events, and to expose their impacts on the environment and on past coastal societies. These different approaches enable us to enhance and refine our knowledge of coastal hazards, but also to apprehend possible storm influences in the context of climate change.
