Dives 3903-4038, July 15, 2003-August 14, 2004

NOTE: It is legally required that all predive checklists be kept. At no time may they be destroyed.

This series begins with Dive 91 and except for the omissions of Dives 92, 346, 463 and 464, 610, continues through Dive 4514. Some early dives have only one sheet of information, but, by 1968, four forms were usually included for each dive: the "Submarine Compensation Computation," the " Alvin Predive Checklist" (which included three parts); a "Debriefing" form and "Post-Dive Checklist." Occasionally other information, such as plotting sheets was included; sometimes computations or other information were written on the folder. Also included in the series are some three, six and twelve month maintenance checklists, and pre- and post-cruise checklists.
