The average vertical distance is given between the neighbour water samples (Fig. 3).
Historical profiles have generally a rather poor vertical resolution, with distances between
samples exceeding 400 meters for depths below 1500 meters. Results depicted in Fig. 3
were used to compromise on the maximum ’’gap” size between the bottles of the cast
allowing a vertical interpolation of water properties. Most of the data were obtained between

1960-1990 (Fig. 4a). An apparent decrease of the data acquisition rate during the last
decade is explained by the lag between the data acquisition and its availability to the
oceanographic community. The overall sampling is biased to the summer period of the
Northern Hemisphere (Fig. 4b).
