Appx_A_Harbor_Bathymetry.xlsx

This file is a bathymetric survey dataset (Appendix A) containing harbor depth measurements and bottom feature descriptions for Kalaupapa, Molokai, Hawaii. The spreadsheet presents coordinates and corresponding water depth readings in a tabular format with over 1,700 data points mapped across the harbor area. Each entry includes an identification number, X-Y coordinates (in what appears to be a local projected coordinate system), depth measurement in feet, and descriptive annotations identifying bottom features such as boulders (BB BOLDERS), reefs (TOP REEF, BTM REEF), pilings (CLPILNG, CLCCPILE), grass beds (G), and various other seafloor characteristics. Notable depth variations range from positive elevations above mean water level (such as 22.1456 feet at point 1109) to depths exceeding 43 feet below surface (such as -43.8999 feet at point 1552). Feature annotations include references to navigational and structural markers like piers, survey stations, benchmarks, and existing coral or reef formations. This bathymetric data serves as baseline environmental and hydrographic information relevant to the Kalaupapa National Historic Park barge service operations, providing essential details on harbor navigability, anchorage depths, and bottom conditions necessary for planning and executing safe maritime transportation to this remote Hawaiian location.
