Correction to “Recent cooling of the upper ocean”

The recent cooling signal in the upper ocean reported by Lyman et al. [2006] is shown to be an artifact that was caused by a large cold bias discovered in a small fraction of Argo floats as well as a smaller but more prevalent warm bias in eXpendable BathyThermograph (XBT) data. These biases are both substantially larger than sampling errors estimated in Lyman et al. [2006].
