A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models
Methods in Ecology and Evolution, EarlyView.Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

Giant pockmarks discovered on the West Greenland shelf
Arctic, Antarctic, and Alpine ResearchPockmarks provide valuable insights into subsurface fluid dynamics, methane release, and potential geohazards. We present the first detailed mapping and characterization of giant pockmarks (>250 m diameter) on the West Greenland continental shelf using ...

Boreas, EarlyView.Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

The magic project: genesis, implementation, and results
Journal of MapsThe Magic Project was conceived following a submarine-generated tsunami at Stromboli in 2002. Recognizing the lack of knowledge on submarine geohazards, the Italian Civil Protection Department launched the project in 2007, aiming to map marine geohazards

Ecology and Evolution, 2021 Seafloor characteristics can help in the prediction of fish distribution, which is required for fisheries and conservation management. Despite this, only 5%–10% of the world's seafloor has been mapped at high resolution, as it is a time‐consuming and ...

Truncated drumlins and their implication for past sea level reconstructions
Boreas, EarlyView.Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...
