<div> <p><span>The meridional circulation and transports at 32<sup>o</sup>S in the Pacific Ocean in 1992 and 2017 are compared with analogous data from 2003 and 2009. The hydrographic data comes from the GO-SHIP database and an inverse box model has been applied with several constraints. In 1992, 2003 and 2017 the pattern of the overturning streamfunction is similar, but in 2009 the pattern of the circulation changes in the whole water column. The horizontal distribution of mass transports at all depths in 1992 and in 2017 changes notably from the “bowed gyre” found in 2009 and resembles that regular shape of 2003. The hydrographic data have also been compared with analogous data obtained from the numerical modelling output of GFDL, ECCO, and SOSE. Results show that the numerical modelling output in the upper layers (</span>γ<sup><span>n</span></sup><span><27.58 kg/m</span><span>3</span><span>) have a roughly similar pattern as hydrographic data. This is not the case, however, for deep and bottom layers (</span>γ<sup><span>n</span></sup><span>>27.58 kg/m</span><span>3</span><span>), where noticeable differences are found. Furthermore, the temperature transport in 2009 </span><span>(0.16 </span><span>± 0.12 PW</span><span>)</span><span> is significantly lower than in 1992 </span><span>(0.42 </span><span>± 0.12 PW</span><span>), </span><span>2003 </span><span>(0.38 </span><span>± 0.12 PW</span><span>) and </span><span>2017 </span><span>(0.42 </span><span>± 0.12 PW</span><span>). In addition, </span><span>the </span><span>freshwater transport result in 2009 (0.50 </span><span>± 0.03 Sv</span><span>) is significantly higher than in 1992 (0.26 </span><span>± 0.08 Sv</span><span>), 2003 (0.25 </span><span>± 0.02 Sv</span><span>) and 2017 (0.34 </span><span>± 0.08 Sv</span><span>). Westward Rossby waves are presumably the dynamical forcing that changes the circulation pattern in 2009. </span></p> </div>

The report by Titian Ramsay Peale on birds encountered during the Wilkes Expedition was withdrawn for inaccuracy when few copies had been distributed, and re-written by John Cassin. A survey of the accounts of the petrels shows that this was not an improvement. Two important type localities for Procellaria brevipes and Thalassidroma lineata are probably wrong, and could be exchanged.
