  1. ODV practical: water masses and CANT distribution In the Indian Ocean OCEAN DATA VIEW http://odv.awi.de/ Marta Álvarez Rodríguez IEO A Coruña Palma, March 2012

  2. OCEAN DATA VIEW http://odv.awi.de/

  3. CANT ALONG CD139 CRUISE (2002) 32ºS INDIAN OCEAN • On board R/V Charles Darwin, CD139 cruise, 1/3 – 15/4/2002, from Durban to Freemantle • P.I.: Harry Bryden (National Oceanographic Centre, Southampton, UK) • Physics: temperature, salinity, ADCP, LADCP • Chemistry: oxygen, salinity, nutrients, CO2 (pH & TA, TIC), CFCs (11, 12, 113), CCl4.

  4. Salinity (psu) CANT ALONG CD139 CRUISE (2002) 32ºS INDIAN OCEAN Africa Australia SAMW SAMW SAMW SAMW AAIW AAIW AAIW AAIW NADW NADW NADW CDW AABW AABW

  5. CANT ALONG CD139 CRUISE (2002) 32ºS INDIAN OCEAN Neutral density layers & salinity Australia Africa Surface SAMW AAIW Deep Bottom

  6. CANT ALONG CD139 CRUISE (2002) 32ºS INDIAN OCEAN • Tasks: • - Map (F8): general Map, extras - gazetter • Station (F9): plot diffrent stations, east, west & central basin • scatter F10: load TS curve configuration (right click-load view TS_curve), Change scale of axis, symbol plot for 3 contrasting stations • - Section F11: Identify water masses: load view Seccion_1 • SAMW, AAIW, CDW, NADW, AABW/WSDW • scatter: Tpot & Salinity characteristics, Depth?, CANT??, • scatter: Plot different CANT vs. Depth • scatter: Plot pCFC12 vs. CANT for upper and deep waters • section: create plots for several CANTs • over the map: selection criteria, select data west of 60ºE • scatter: plot CANT-SAB99 vs. All the other CANT • scatter: NO3 vs. PO4, NO3 vs. Oxygen, do they follow redfield?? Over the data click F4 (statistics)
