CONTROL CHART
All continuously recorded echo-sounding profiles used in preparation of Plates 1 and 20 are shown. Solid lines indicate Lamont Geological Observatory and Woods Hole Oceanographic Institution cruises. Dashed lines indicate soundings supplied by British Admiralty. Lines shown by alternate long dash and two short dashes indicate closely spaced discrete soundings of METEOR.

SIX TRANS-ATLANTIC TOPOGRAPHIC PROFILES
Soundings in fathoms continuously recorded by an NMC echo sounder on the R. V. ATLANTIS. The letters a—q indicate where soundings from different cruises were joined.
