Scientificobjectives

Sloyan,Wijffels,Tilbrook,Warner,Bodrossy,Downes:Thefullsuiteofkeyoceanparametersandthedeepoceanheatandcarbonreservoirsremainpoorlymeasured.Thisproposalwillcompletefull-depth,high-precisionhydrographic,carbon,andtracermeasurements,along170oWfromthesea-iceedgetotheequator,tomonitoranddetectoceanvariabilityandchangeincludingchangesinthecarbonatechemistryassociatedwithacidification.Thesedata,togetherwithotherobservationaldataandnumericalmodels,willallowforthedetectionandattributionofoceanchangeandvariabilityandtoassesstheimpactoftheoceanonclimatevariability.Thishydrographicsectionwillmonitoroceanchangeandvariabilityby:

1. Directlymeasuringthefullsuiteofoceanwaterproperties(temperature,salinity,velocity,nutrients,tracersandoceanmixing)athighverticalandspatialresolutionthroughouttheentirewatercolumnandinthedeepboundarycurrents,contributingtotheinternationalGO-SHIPprogram

2. Providinghighprecisionbiogeochemicalmeasurementstomonitorchangesinoceancarbonstorageandoxygenconcentrations,contributingtotheIOCCPinternationalprogramtomonitortheglobalcarbonbudget.

3. DirectlymeasureoceanmixingtoimproveourknowledgeoftheoceanMeridionalOverturningCirculation.

4. ProvidehighprecisionbaselinedatatocalibratetheArgoarray,XBTprogram,andotherautonomousobservations(oceangliders,mooringsandsatellites)inthevicinityofthesection.

5. DeployArgofloatsforthecoremissionandcontributionstotheinternationalSOCCOMproject.

6. Map,forthefirsttime,thegenomiccharacteristicofmarinebacteriaandphytoplanktonalong170°W,aspartofalargersetofsurveysbeingcarriedoutaroundAustralia.

7. Obtainside-by-sideCTD/XBTdatafortheassessmentofbiaserrorsinXBTmeasurements.8. ObtainTritium/HeliummeasurementsintheAntarcticCircumpolarCurrent.
