Coastal planners need to know the flood risk from tidal surges so sea defences can be sited appropriately. The author has developed a novel technique which analyses tide gauge data to estimate the risk and the height of sea-defences required. A comparison with results of a UK Environment Agency 2011 study shows good agreement. However, this new approach is simpler to automate than the method used in that study, and could be widely used to inform strategies for coastal management and resilience.

This study shows a new method for mapping coralligenous bioconstructions using high-resolution acoustic data. The protocol integrates bathymetry, backscatter, and geomorphological indices, providing detailed information on the spatial and volumetric distribution of benthic habitats. This approach offers valuable insights for monitoring and conserving Mediterranean ecosystems, with potential applications in understanding habitat structure and guiding future conservation actions.

Estimating Particulate Organic Carbon (POC) relies on proxies like the particulate backscattering coefficient (b_bp) derived from BioGeoChemical-Argo (BGC-Argo) floats and satellite data. BGC-Argo floats provide global insights into vertical bio-optical dynamics. This study integrates Sentinel-3 data and machine learning approaches to improve b_bp estimates in the top 250 meters of the water column. Results are promising in stable global oceanic areas but less consistent in more dynamic regions.

A combined procedure of benzalkonium chloride (BAC) addition and filtration was investigated to preserve water samples for radiocarbon analysis of dissolved inorganic carbon (DIC). The results indicated that DIC changes can be effectively suppressed during sample storage for up to 41 weeks. This procedure offers a practical, environmentally friendly alternative to conventional mercury-disinfected methods, effectively water sample preservation samples in aquatic environments.
