Relative Sea-Level Rise Along the U.S. Gulf Coast, 2003-2021

The U.S. Gulf Coast faces challenges from rising sea levels, hurricanes, and land subsidence. This dataset, created by Ashraf Rateb and hosted by the Texas Data Repository, uses advanced statistical methods to analyze drivers like ocean warming, ice-sheet melt, and local land motion from 2003 to 2021. It captures non-linear accelerations and slowdowns in sea-level change, with findings showing faster rise near Florida and critical subsidence in parts of Louisiana and Texas.

Use Cases

• Modeling coastal flood risk based on nearshore sea-level rise rates mentioned in the description
• Analyzing the contribution of land subsidence to relative sea-level change based on the described local land motion factor
• Investigating short-term variability in sea-level drivers based on the described time-varying statistical approach
• Comparing regional sea-level trends between Florida, the central Gulf, and west Texas based on the described geographic differences

Strengths

• Covers a 19-year time series from 2003 to 2021
• Analyzes multiple physical drivers including ocean warming, circulation, ice melt, and land motion
• Uses a non-linear statistical method that captures abrupt accelerations and slowdowns
• Includes coastal altimetry data revealing nearshore rates around twice as large as open-ocean measurements

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
