| Title | Paper, 'Tables of temperatures of the sea at different depths beneath the surface, reduced and collated from the various observations made between the years 1772 and 1868 with notes and sections' by Joseph Prestwich |
| Date | 1874 |
| Description | The present paper contains a record of about 1300 observations, which are arranged according to the degrees of latitude: for the northern hemisphere, the southern hemisphere and the inland seas. They are all reduced to common scales of thermometer, measure of depth, and meridian. Their position is given on a map of the world, and the bathymetrical isotherms from the Poles to the Equator, based on the correct and corrected observations, are given in a series of ten sections. Prestwich does not claim for these observations the exact value, or the unity and completeness of plan, of the more recent ones, while, as compared with them, the depths at which they were made are on the whole very limited; still they include a few at great depths; and as they extend over much ground that has not been covered by the expeditions of the ‘Lightning,’ 'Porcupine,’ and 'Challenger,’ he trusts that these tables may be of some use as complemental to these later researches, and as bringing together and reducing to a common standard, observations scattered through a large number of works and memoirs.
