«Mixing it up: Study provides new insight into Southern Ocean behavior.» (sciencedaily.com)
What I didn't see was mention of the role greenhouse gasses play on ocean behavior, an area of intense study since it was discovered that oceans have been taking up much of our excess CO2, may be near the saturation point, and may endanger shellfish and reefs due to more acidic seawater.

For example, due to the lack of ocean data, secondary data is often used to infer what the ocean is doing — thus, the AMO analysis relies not on ocean temperature measurements, but rather on air pressure measurements as a proxy for ocean behavior — iffy at best. (realclimate.org)
