Bathymetry (seafloor depth), is a critical parameter providing the geospatial context for multitude of marine scientific studies. Since 1997, International Bathymetric Chart Arctic Ocean (IBCAO) has been authoritative source bathymetry Ocean. IBCAO merged its efforts with Nippon Foundation-GEBCO-Seabed 2030 Project, goal mapping all oceans by 2030. Here we present latest version (IBCAO Ver. 4.0), more than twice resolution (200 × 200 m versus 500 m) and individual depth soundings...

A field of sediment undulations has been mapped by means high‐resolution multibeam bathymetry and seismic reflection profiles in the Llobregat River prodelta, off city Barcelona, Catalonia, Spain. Similar features had previously recognized other prodelta environments interpreted either as downslope deformation or sedimentary structures induced bottom currents hyperpycnal flows. Since study area is undergoing significant offshore development, proper interpretation such needed for a correct...
This article presents a reasonable present-day, sea-level highstand numerical simulation and scenario for potential tsunami generated by landslide with the characteristics of BIG'95 debris flow, which occurred on Ebro margin in western Mediterranean Sea prehistoric times (11,500 cal yr BP). The submarine deposit covers an area 2200 km2 slope base (200–1800-m water depth), involving volume 26 km3. A leapfrog finite difference model, COMCOT (Cornell multigrid coupled model), is used to...
The tsunami induced by the May 21, 2003, Algerian Boumerdès-Zemmouri earthquake (moment magnitude Mw = 6.9) propagated across western Mediterranean Basin, thereby causing material damages in some harbors and coastal areas. This was case Balearic Islands particularly Palma harbor. Attempts to simulate 2003 event found discrepancies between arrival times wave amplitude when comparing tide gauge records with results from numerical models. To date, all published model of are underestimations,...
Abstract Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, safety of navigation, and ocean exploration. Mapping the central Arctic Ocean challenging due to presence perennial sea ice, which limits data collection icebreakers, submarines, drifting ice stations. The International Bathymetric Chart (IBCAO) was initiated in 1997 with goal updating bathymetric portrayal. project team has since released four...
The northern Antarctic Peninsula (NAP) forms a narrow stretch of land that extends to relatively low latitude (63° S) and is subject humid, maritime-influenced climate, especially on its western side. During the Last Glacial Maximum (LGM), NAP was covered by part Ice Sheet (APIS) (Lavoie et al. 2015). APIS fed ice streams flowing both sides NAP, including Gerlache–Boyd Stream (GBIS) (Canals 2000). Fast-flowing are most dynamic components sheets largely determine ice-sheet mass loss stability...
During the tsunami of May 2003 in Balearic Islands, generated by Algerian earthquake, most damage and economic losses occurred inside harbours, due to high frequency oscillations relatively large amplitude, combined effect local resonances. It can be said fact that this was more important at islands, where no inundations is known have outside showing up even tsunamis with low amplitudes cause serious damages resonance effects. Several tide gauges recorded seismic-generated tsunami, so...
During the Last Glacial Maximum (LGM), ice masses covering western side of northernmost Antarctic Peninsula (NAP) drained into Bransfield Basin (BB) (Banfield & Anderson 1995). A drainage-basin area about 60 000 km2 generated an flux that entrained significant volumes englacial and subglacial debris were subsequently delivered BB. Multibeam-bathymetric data show a number deeply sculpted, sub-parallel glacial cross-shelf troughs associated landforms within framework entire depositional system...
The western Mediterranean Sea includes several archipelagos of which the largest ones are, from west to east, Baleares (Balearics Islands) and Corsica Sardinia block. sea area between Sicily represents transition Ligurian Ionian seas. continental shelves are particularly rich in submerged terrestrial coastal landforms that formed during past sea-level lowstands, with last imprint attributed Last Glacial Maximum. Climate oscillations Quaternary induced major changes faunal distribution both...
El principal objetivo de este trabajo es evaluar las variaciones espaciales y temporales anchura el comportamiento sedimentológico a medio-corto plazo (2004 2020) playas del norte Golfo Roses (NO Mediterráneo, España). La zona estudio cubre 10 km en la parte golfo. Se emplearon dos metodologías SIG para cuantificar los cambios costeros por transectos áreas. recolectaron muestras sedimento tanto playa seca como áreas lavado cada transecto. análisis basado perfiles muestra una tasa anual...
This study conducts a morphodynamic analysis of beaches located in the northern sector Gulf Roses (NW Mediterranean, Spain). The primary objective is to investigate mid-short (2004–2020) term spatial and temporal variations shoreline position sedimentological behaviour. area covers part gulf, spanning 9.86 km, includes both natural heavily anthropized ones. following GIS methodologies were employed coastline: QGIS for areas DSAS-ArcGIS transects, quantifying coastal changes from 2004 2020....
