dentis, liches and tuna, tend to rarify when the waters begin to cool towards midNovember.
This rarefication of tepid water fish from the beginning of the cold season continues
until only the bass remain. During winter, when water temperatures are stabilized at
about 13
◦ C, it is not rare to come across an anglerfish or a shoal of squid.
All these biological signals affect the diver’s “biological landscape” and “phenological landscape”. . . And the diver’s mood also changes with the winds and the
seasons.
5.4.5 Meteorology and “Mental Landscapes”
In many respects, the “geopsyche” (Hellpach 1943) of our mental landscape seems
to be under meteorological control in Marseilles. We could allude here to common
figurative expressions such as; to be depressed, to be “pumped up”, “under pressure”,
“a storm is brewing”, “a breeze of optimism”. The reputed versatile and whimsical
mood changes associated with the Marseilles population seem to be very much in
keeping with this variable weather which can change in all respects in less than a
few hours; wind direction and intensity, cloud cover, light and population moods. . .
