I found to my great surprise at this enormous depth – not, as might be presumed according to Forbes' hypothesis – a poor and oppressed Fauna, but on the contrary a richly developed and varied animal life; so that my father (Michael Sars) was able in 1869 to increase the catalogue of the forms of animal life observed at the depths of 200–300 fathoms, by the addition of not less than 335 species (in all 427) of which nearly all were taken at one locality, namely the fishing place Skraaven in Lofoten.
We may therefore, … presume that the Cretaceous formation is continued undisturbed at this present day in the depths of the Ocean … while the Fauna at smaller depths, and especially the shore-Fauna, would in relatively short time, by reason of telluric and physical revolutions, be forced entirely to change its character.
G.O. SARS 1872.Abstract
It has been claimed that just as on land the marine domain shows a cline of increasing diversity from poles to tropics. Recent data however, suggest that this may only hold for the northern hemisphere. On land there is a gradient of decreasing diversity with altitude. A marine counterpart has been suggested, but here with an increase in diversity with increasing depth. The original data on which this gradient was postulated are examined critically in the light of new data.
