Argo and GODAE OceanView

GODAE OceanView – November 16, 2011

P.Y. Le Traon from D. Roemmich OSTST presentation

Argo and GOV (1)

Argo challenge and priority 1 : complete and sustain the global array.

• Still a challenge.

• Need convincing cases from GOV (and others) on the use and utility of the array. GOV OSEVal TT results should be regularly communicated to Argo project office.

• Improvements in float technology are providing increases in float lifetime, better data quality, much higher vertical resolution in profiles, and better near-surface data (GOV needs ?).

Argo and GOV (2)

Argo challenge and priority 2 : preparing the next decade of the Argo mission

(biogeochemistry, deep ocean, seasonal ice, marginal seas, sampling, etc).

• What are the GOV requirements ?

• OSE/OSSEs works from GOV teams much needed but they require careful framing and interpretation

• (joint GOV/Argo works)

Southern Ocean OSSEs Andreas Schiller

Researchers need information about the design of the future SouthernOcean Observing system (CLIVAR/CliC/SCAR Southern Ocean Region Implementation Panel)

Proposed foci (Steve Rintoul), in order of priority:

divergence of heat and fresh water fluxes as f(x,t)

ventilation rates (density fluxes) in Southern Ocean

how frequently (where and when) to measure under ice;

seasonal-to-interannual variability (when, where, how frequently)
