Gulf of Mexico High-Resolution (0.01° x 0.01°) Bathymetric Grid - Version 1, August 2011

High resolution (0.01° x 0.01°)Gulf of Mexico bathymetric grid, version 1.0 generated in August 2011. Data are in HYCOM native format. Luis Zamudio-Lopez (NRL, [e-mail]) kindly offered an initial 1=100°(~1000 m) bathymetric grid for the regionThis grid has been computationally modified and substantially hand edited (a) to better match the shoreline definition, (b) fill the voids in the water depths and (c) if possible, to more accurate represent the interpolated water depths. The final numerical grid conforms to the 1=25°(~4000 m) North Atlantic HYCOM computational domain, where they are both matched at 76:40 oW longitude. Data used in the development of the new grid include GSHHS: A Global Self-consistent, Hierarchical, High-resolution Shoreline Database, GEBCO 30 arc-sec global grid, and the National Geophysical Data Center’s (NGDC) 6 arc-sec U.S. Coastal Relief Model database, volumes: 2, 3, 4 and 5.

高分辨率（0.01°×0.01°）墨西哥湾水深栅格数据集，版本1.0，于2011年8月生成，数据采用HYCOM原生格式。路易斯·萨穆迪奥-洛佩斯（Luis Zamudio-Lopez，美国海军研究实验室NRL，邮箱：[e-mail]）为该区域提供了初始的1/100°（约1000米）分辨率水深栅格。随后对该栅格开展了计算修正与大量人工编辑：(a) 优化岸线匹配精度；(b) 填补水深数据空白；(c) 尽可能更精准地呈现插值水深结果。最终生成的数值栅格适配1/25°（约4000米）分辨率的北大西洋HYCOM计算域，二者在西经76°40′处完全匹配。本次新栅格开发所采用的数据源包括：全球自洽分层高分辨率岸线数据库（GSHHS, Global Self-consistent, Hierarchical, High-resolution Shoreline Database）、GEBCO 30角秒全球水深栅格，以及美国国家地球物理数据中心（NGDC, National Geophysical Data Center）发布的6角秒美国海岸地形模型数据库第2、3、4、5卷。
