Gulf of Mexico vs. US Southeast Region: South of the Border
The Gulf of Mexico lies directly south of the US Southeast Region—a 1,600 km (1,000 mi) watery border separating the region from Mexico, Cuba, and the Caribbean.
Southeast Region States (US Census Definition)
- Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia
Note: Only AL, FL, LA, MS, TX (not in Census SE) have Gulf coastline. TN, AR, NC, SC, VA, GA are Atlantic or inland.
Gulf's Strategic Geometry
| Metric | Value |
|---|
| Surface area | 1.55 M km² (600k sq mi) |
| Max depth | 3,750 m (Sigsbee Deep) |
| Coastline (US only) | ~2,700 km |
| Major ports | Houston, New Orleans, Mobile, Tampa, Corpus Christi |
| Key straits | Florida Straits (to Atlantic), Yucatán Channel (to Caribbean) |
Why the Relationship Matters
- Hurricane highway: Gulf warm loop current fuels rapid intensification before SE landfall
- Oil & gas: 15% US crude production, 45% refining capacity on Gulf Coast
- Fisheries: 40% US commercial landings by weight (shrimp, menhaden, oysters)
- Dead zone: Mississippi nutrient plume → hypoxic zone (up to 22,000 km²) off LA/TX
The Gulf isn't just "south of the Southeast"—it's the region's climate engine, economic lung, and ecological responsibility.
