119 Appendix F HYPSOMETRY DATA NR-2 depth requirements were determined, in part, from examina- tion of ocean depths in various regions of the world. Hypsometry data provided by the Woods Hole Oceanographic Institute, along with detailed hydrographic information from the Defense Mapping Agency, were used for these decisions. Samples of the Woods Hole data are provided for information purposes in this appendix for three representative regions: the North Atlantic, the North Pacific, and the Indian Ocean. Global hypsometry distribution is displayed below.
