[1] In the paper “Latitudinal dependence of diapycnal diffusivity in the thermocline observed using a microstructure profiler” by T. Hibiya et al. (Geophysical Research Letters, 34, L24602, doi:10.1029/2007GL032323) there were textual errors inadvertently overlooked during the production proofing process. [2] The second sentence in Paragraph 5 should read as follows. In the present study, we deployed the velocity microstructure profiler TurboMAP-D to a depth below the main thermocline at 53 locations in the interior Pacific Ocean between 53°N and 10°S (Figure 1). [3] Paragraph 9 should read as follows. Figure 3 shows the average diapycnal diffusivities over the depth range of ∼1000 m to ∼1600 m inferred from microstructure observations (hereinafter referred to as KρMSP) and those inferred by incorporating XCP data into Gregg's fine-scale parameterization [Gregg, 1989] (hereinafter referred to as KρPRM). [4] The third sentence of paragraph 10 should read as follows. The latitudinal distribution of KρMSP thus obtained from microstructure observations is in qualitative agreement with predictions based on parameterized estimates KρPRM at mid- and high-latitudes (poleward of 20°N) [Nagasawa et al., 2002; Hibiya and Nagasawa, 2004; Hibiya et al., 2006] and previous microstructure observations at low latitudes (equatorward of 20°N) [Gregg et al., 2003], although fine-scale parameterizations overestimate diapycnal diffusivities by a factor of 2–3. [5] The first sentence of paragraph 12 should read as follows. By deploying the un-tethered free-fall microstructure profiler called “TurboMAP-D” at 53 locations in the interior Pacific Ocean between 53°N and 10°S, we have examined the efficacy of the latitudinal dependence of diapycnal diffusivity in the main thermocline predicted based on parameterized estimates at mid- and high-latitudes [Nagasawa et al., 2002; Hibiya and Nagasawa, 2004; Hibiya et al., 2006] and previous microstructure observations at low-latitudes [Gregg et al., 2003]. [6] The second sentence of paragraph 13 should read as follows. One of the strong candidates that might make up for the deficiency of diapycnal mixing in the main thermocline is thought to be intense diapycnal mixing above abyssal rough bottom topography [Polzin et al., 1997; Ledwell et al., 2000].

Niwa (2005), Bispectral analysis of energy transfer within the two-dimensional oceanic internal wave field, J. Phys. Oceanogr., 35(11), 2104–2109. [8] Ledwell et al. [1993] reference should be replaced with the following reference.Ledwell, J. R., E. T. Montgomery, K. L. Polzin, L. C. St. Laurent, R. W. Schmitt, and J. M. Toole (2000), Evidence for enhanced mixing over rough topography in the abyssal ocean, Nature, 403, 179–182. [9] The journal in Munk [1966] reference was incorrect. The reference should read as follows.Munk, W. (1966), Abyssal recipes, Deep Sea Res., 13(4), 707–730.
