The role of the oceans in the climate system

Observing the ocean…

“That's life at sea: you get what you get and you don't get upset.”Martin Visbeck, GEOMAR.

Ship Observations (SOOP/VOS)

Repeat Hydrography

Argo: a revolution in Oceanography: routine global subsurface ocean observations

The challenges of sustaining observations

New Technologies…

Animal Tagging: Elephant Seals

• Mapping under the sea ice for the first time (complement Argo)

Charassin et al., 2008 From Steve Rintoul

Key messages

• Understanding the ocean is essential to understanding our climate system, and our ability to predict it. – Absorbing most of the excess heat, and a large chunk of the

carbon. – Drives inter-annual variability in the tropics, and decadal variability

at mid-latitudes.

• We are only beginning to see the benefits of a comprehensive subsurface ocean observing system. – Enabled by advances in communications and data services.

Thank you!
