boston.sub - Records of daily water temperatures and salinity observations for the period Jan. 1956 - Dec. 1971. MBT (mechanical bathythermograph) slides read at 15 meter intervals by group at Woods Hole Oceanographic Inst. This file is data digitized from U.S.C.G. Oceanographic Reports by the Orkand company at NCDC in fall of 1998. Information regarding keying format can be found here. See list of U.S.C.G. Report Data above for actual depth of measurements and changes in locality and water depth of the Lightship and look here for more background information.

intervals given to K. Elder by George Hiemerdinger who read it from an NCDC CDROM.   Information regarding data format can be found here.
Apparently there were two groups reading the mbt slides, one at Woods Hole whose work was published in the Coast Guard Reports, and the other at NCDC. The NCDC group read the slide at 5 meter intervals whereas the WH group read them at 15 meter intervals.
