An array of five moorings was deployed at 23°S off eastern Madagascar as part of the Indian–Atlantic Exchange in present and past climate (INATEX) observational program. On average, the EMC has a horizontal scale of about 60–100 km and is found from the surface to about 1000-m depth. Its time-averaged core is positioned at the surface, at approximately 20 km from the coast, with velocity of 79 (±21) cm s-1. The EMC mean volume transport is estimated to be 18.3 (±8.4) Sverdrups (Sv; 1 Sv = 106 m3 s-1). During the strongest events, maximum velocities and transport reach up to 170 cm s-1 and 50 Sv, respectively. A good agreement is found between the in situ transport estimated over the first 8 m of water column [0.32 (±0.13) Sv] with the altimetry-derived volume transport [0.28 (±0.09) Sv]. Results from wavelet analysis display a dominant nearly bimonthly (45–85 days) frequency band of transport variability, which explains about 41% of the transport variance. Altimeter data suggest that this band of variability is induced by the arrival of westward-propagating sea level anomalies, which in turn are likely represented by mesoscale cyclonic and anticyclonic eddies. Annual averages of the altimeter-derived surface transport suggest that interannual variabilities also play a role in the EMC system.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The East Madagascar Current: Volume Transport and Variability Based on Long-Term Observations","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Geographic location/entity; Indian Ocean; Circulation/ Dynamics; Boundary currents; Eddies; Mesoscale processes","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2019-05-27","DateCreate":"2016-04-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000372810700002","VABBcode":null,"OpenAcc":1,"DOI":"10.1175/JPO-D-15-0154.1"},"refs":null,"anarec":{"AnaID":255099,"PubliDate":2016,"Pagination":"1045-1065","XtraPublOfAnaID":null,"ISBN":null,"Volume":"46","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43252,"SerRR":"Journal of Physical Oceanography.
