Appendix F

HYPSOMETRY DATA

NR-2 depth requirements were determined, in part, from examina-tion of ocean depths in various regions of the world. Hypsometrydata provided by the Woods Hole Oceanographic Institute, alongwith detailed hydrographic information from the Defense MappingAgency, were used for these decisions. Samples of the Woods Holedata are provided for information purposes in this appendix for threerepresentative regions: the North Atlantic, the North Pacific, and theIndian Ocean. Global hypsometry distribution is displayed below.
