Presentation Transcript

  1. PO1/IFM-GEOMAR Tropical Atlantic Projects • 2 cruises (Aug. 2004 / Spring 2006) • 2 funded projects • 1 proposed project

  2. * Moorings Apex floats RAFOS floats • Meteor cruise M62/2 Aug. 2004 • recovery of CLIVAR array at 11°S • deployment of current meter mooring at 35°W at the equator (upper 1500 m) • deployment of two sound sources • release of 15 APEX and 42 isopycnic RAFOS floats

  3. Meteor cruise Spring 2006 • recovery of current meter mooring at 35°W on the equator • recovery of sound source moorings • microstructure measurements • deployment of APEX floats

  4. ARGO – Tropical Atlantic (Fischer/Schott) • 15 APEX floats will be deployed during Meteor cruise M62/2 (Aug. 2004) • 15 APEX floats during 2005/2006

  5. STC study using isopycnic RAFOS floats (Schott/Brandt) Climatological depth of isopycnalsq=25.7 kg/m³ [m] RAFOS Deployment 42 RAFOS-floats will be deployed during M62/2 (Aug. 2004) at two isopycnic surfaces: sq=25.7 kg/m³ and sq=26.8 kg/m³

  6. Glider-section at 23°W (Guinea Dome and equatorial hydr.) Repeat ship sections including microstructure measurements Proposed Research Program Mooring array at 23°W (EUC transport and hydrography)

  7. Vermessung intrasaisonaler bis interannualer Schwankungen von Stärke und Wassermasseneigenschaften des ostwärtigen Warmwassertransports zur Versorgung der Auftriebsgebiete im östlichen tropischen Atlantik • Verbessertes Verständnis der Wärmebilanz der Deckschicht im zentralen äquatorialen Atlantik (verbesserte Parametrisierungen zur Ableitung der verschiedenen Terme aus Satelliten- und Drifterdaten) • Analyse von gekoppelten und ozeanischen Modellen hinsichtlich • der Rolle von Oberflächentemperaturschwankungen für Niederschlagsanomalien im Bereich des tropischen Atlantiks • der Rolle von STC und MOC Schwankungen für Temperaturanomalien im Ostatlantik (Stärke des EUC und Aufteilung zwischen süd- und nordhemisphärischem Wasser)
