Abstract Greenland's bed topography is a primary control on ice flow, grounding line migration, calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warm Atlantic water (AW) that rapidly melts undercuts marine‐terminating glaciers. Here we present new compilation Greenland assimilates seafloor thickness data through mass conservation approach. A 150 m horizontal resolution topography/bathymetric map constructed with seamless transitions at...
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...
The term vulnerable marine ecosystems (VMEs) was introduced to facilitate the spatial management of deep-seas, identifying those habitats anthropogenic disturbance, such as trawling. Consistent interpretation VME definition has been hampered by a underlying paucity knowledge about nature and distribution deep-sea habitats. Photographic video platforms yield data rich, quantifiable imagery address these gaps. A low-cost towed benthic sled used investigate trawling impacts in west Greenland....
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...
Abstract The offshore Greenland halibut (Reinhardtius hippoglossoides) fishery, west Greenland, employs demersal trawl gear at depths of 800–1400 m. In contrast to many deep-sea fisheries, the target stock appears stable and fishery is significant economic importance. Recent Marine Stewardship Council certification this highlighted paucity knowledge benthic habitats trawling impacts, which study aimed address using a towed video sled. spatially discrete northern southern areas were found be...
In this paper we describe seafloor terrain of nearly the entire Disko Bay region and provide scientific baseline information about surface geology sedimentary environments that can support management plan in Greenland. Our study utilized multiple datasets multibeam bathymetry backscatter, seismic profiles ground-truthing consisting video footage from drop camera benthic sled, as well sediment samples grab corers. results revealed key geological units characterize scale geomorphic features,...
Abstract A healthy ocean where marine habitats and ecosystems are mapped protected is one of the UN's Sustainable Development Goals to sustainably use resources. Our study presents first high‐resolution benthic habitat map from Greenland integrating analyses multibeam bathymetry backscatter data, ground‐truth data including video sled, drop camera day grab. The pilot area 30 × 20 km located on continental shelf in central Disko Bay, West all were collected a single, 10‐day survey. Multibeam...
Rapid environmental changes due to climate change call for innovative technological approaches, and likewise is this required security missions. Essentially, organizations like NATO need advanced capabilities allowing geographically distributed joint mission forces with all their information sources consumers (i) operate off the same map (ii) get right data at moment. Datacubes, aka spatio-temporally homogenized raster data, are an accepted cornerstone providing Big Geo Data easier users...
