We performed a multi-scale characterization of seafloor topography of the MAR. In the basin-scale analysis, we have used the 30\" General Bathymetric Chart of the Oceans (GEBCO) grid to estimate the area of different components of lower bathyal habitat in the main North Atlantic basin and to produce a corresponding depth-area relationship. The regional-scale investigation is based on swath bathymetry surveys which show the flanks to MAR to comprise a series of sediment-draped flat plains (37.65% of area) with intervening gentle slopes ranging from 5 degrees to 30 degrees (56.70% of area) and slopes steeper than 30 degrees (5.65% of area). The steep slopes have significant areas of hard substrate (70%) comprising bare cliff faces and rock outcrops. Within the local-scale approach, detailed surveys of such steep areas were done by multi-beam sonar and cameras mounted on a Remotely Operated Vehicle (ROV). In several locations, the terrace-like seafloor topography has also been identified. Overall, it has been shown that the MAR lower bathyal is 95% covered with soft sediment.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A multi-scale investigation into seafloor topography of the northern Mid-Atlantic Ridge based on geographic information system analysis","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:32:52.928458","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Mid-ocean ridge; Bathymetry; Sea-floor topography; Seamount; Benthos;Bathyal; Sediment; Atlantic Ocean; Geographic Information System (GIS);Remotely Operated Vehicle (ROV)","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2016-02-18","DateCreate":"2016-02-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000330491000003","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.dsr2.2013.10.006"},"refs":null,"anarec":{"AnaID":252994,"PubliDate":2013,"Pagination":"231-243","XtraPublOfAnaID":null,"ISBN":null,"Volume":"98","Issue":"Part B","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45197,"SerRR":"Deep-Sea Research, Part II.
