             ON THE BED OF THE PACIFIC

      We call our world «the earth», but really nearly three quarters
of its surface is covered by the deep waters of the great oceans. The
land surface of the globe is well known today, but we do not know
much about the bed of the sea, particularly the floor of the deep
ocean.
      In the past years four large oceanographic expeditions from
various countries studied ocean depths. Three of them — the Swed-
ish, the Danish and the British expeditions — were «round-the-
world» expeditions.
      The Russian expedition on the «Vityaz» worked on a smaller
area in the North-West Pacific. Sent by an Institute of Academy of
Science, the motor-shi p «Vityaz» was equi pped for exploration of
the sea at any depth. It had all the necessary instruments — hydrolog-
ical, hydrochemical and geological. Sixty scientists could live and
work on the «Vityaz». It had 14 fully equi pped laboratories. The
