Abstract Off Northeast Greenland, the Wandel Sea extends between Morris Jesup Rise and Gakkel Ridge as an area where rapid environmental changes are driven by complex interactions between the ice sheet, ocean, and sea ice. However, geological data that can illuminate long-term trends are virtually missing. We hereby present novel sub-bottom and swath bathymetry data acquired on the Arctic margin …

Estuarine ecosystems are highly dynamic environments that provide critical ecological functions but remain vulnerable to anthropogenic pressures. In this study, we investigated long-term sedimentary processes and their geomorphological consequences on habitat dynamics of the sedge Bolboschoenus planiculmis (Scirpus planiculmis) in the Nakdong River estuary, South Korea. By integrating high-resolu…

Accurate knowledge of the seafloor is fundamental for understanding marine geomorphology, ecosystem distribution, and sustainable use of ocean resources, yet knowledge distribution remains uneven across ocean basins. This study presents the first spatially explicit bibliometric analysis of seafloor-mapping research (i.e., bathymetric studies) in the Mediterranean Sea, synthesizing georeferenced s…

High-resolution paleoenvironmental reconstruction is crucial for understanding past climate dynamics and predicting future climate changes. Holocene oyster reefs (Crassostrea gigas) on the coastal plain of the western Bohai sea serve as valuable archives for deciphering the paleoclimate fluctuations. Micro-scale sclerochronology study of individual oyster shells and macro-scale analysis on reef d…

Beaches worldwide play an essential role in shore protection under storm conditions. How to identify the threshold beach width for effective shore protection remains largely unresolved due to a scarcity of measured beach profiles with sufficient temporal and spatial resolutions. In this study, weekly to monthly surveys spaced 100 m along the shoreline have been conducted at Ortley Beach, New Jers…

Abstract A variety of geological processes shape and modify the morphology of volcanic islands over a range of temporal timeframes. Amongst the most conspicuous are aerial and submarine landslides that are frequently observed in both island arc and intra-plate volcanic settings. Identifying and understanding the triggering mechanisms of these landslides is crucial to geohazard mitigation as they …

Abstract The 1956 Amorgos earthquake, with a magnitude of Ms = 7.5, caused a destructive tsunami in the Central Aegean Sea. Two gravity cores were collected south of Amorgos and Anafi Islands, respectively, confirming submarine landslide deposits linked to the 1956 earthquake. The 1956 Mass Transport Deposits (MTDs) vary in thickness from 55 to 100 cm in the cores. The predominant fraction of the…
