AMS Style for Geography and Oceanography Terms

Geography Terms

The American Meteorological Society remains neutral with respect to land-based political borders and names or references to land-based locations in AMS journals. However, no borders or territorial boundaries should be shown over oceans and adjacent seas, gulfs, or other oceanic water bodies on figures in AMS publications.
