September 20, 2024
Coastal erosion threatens the loss of Native American cultural heritage and archaeological sites located along our coastlines, reducing opportunities to increase knowledge of past communities and environments. This project leverages an advisory team of ancestral Tribes, coastal managers, and archaeologists to strengthen the effectiveness of coastal hazard data, focusing on assessing the vulnerability of shell mound sites to erosion and flooding from future sea level rise and storms.
Shoreline erosion puts cultural heritage sites at risk
Shoreline erosion puts cultural heritage sites at risk
Estuarine habitats provide important environmental services, such as habitat for wildlife and protection for coastal communities from storm surge, and also contain Native American cultural artifacts within shell middens (also called shell mounds). However, these habitats are increasingly at risk to erosion and flooding from sea level rise and storms.

What are shell middens?
What are shell middens?
When sea level was lower, Indigenous communities lived near the coast, where they harvested oysters and other foods, creating waste piles of shells, pottery, beadwork, and other materials. These piles, known as shell middens, are an integral part of Native American history and culture. As coastal landforms naturally changed over time, much of the surrounding area became wetlands, beaches, and barrier islands. In addition, the ecology of shell middens are distinct because they are often a different elevation and structure than the surrounding habitat. Sea level rise and increased severe storms are escalating shell midden vulnerability to submergence and erosion, putting ecological diversity and cultural artifacts at risk.

Knowledge and tools to assess cultural site vulnerability
The objectives of the Cultural Heritage at Risk (CHART) project are to capitalize on existing research on coastal hazards, coastal management, and Indigenous knowledge by 1) building an advisory team of ancestral Tribes, state archaeologists, and land managers to guide the creation of a tool that increases awareness of cultural site vulnerability to erosion and submergence, 2) identifying cultural sites that are at the greatest risk to erosion and flooding, focusing on Apalachicola and Grand Bay National Estuarine Research Reserves as pilot study sites, and 3) increasing Indigenous representation in coastal, oceanographic, and archaeological sciences by engaging students through internships and educational opportunities.

Estuarine Shoreline Change Research Project
The goal of the estuarine shoreline change project is to define shoreline positions for historical and modern wetland shorelines and calculate rates of change along the U.S. East and Gulf coasts.
Estuarine and MaRsh Geology Research Project
The goal of the Estuarine and MaRsh Geology (EMRG) Research Project is to study how and where short- and long-term marsh and estuarine coastal processes interact, how they influence coastal accretion or erosion, and how they pre-condition a marsh’s resiliency to storms, sea-level change, and human alterations along the northern Gulf of Mexico (Grand Bay and Point aux Chenes, Mississippi and St...

Rock breakwaters are used to protect marsh shoreline from erosion
The estuarine shoreline of barrier islands along the Gulf of Mexico are vulnerable to shoreline erosion. Structures, such as this rock breakwater, can be used to protect the shoreline from erosional waves.

Native American shell middens along many coastlines are vulnerable to shoreline erosion
These shells are what remains of a Native American shell midden that is located along an actively eroding shoreline in Apalachicola Bay.

Rapid salt-marsh erosion in Grand Bay, Mississippi
This time-lapse video shows lateral erosion of a salt marsh in the Grand Bay National Estuarine Research Reserve, part of an embayment near the city of Pascagoula, Mississippi, on the US Gulf coast. Wave action over the course of 6.5 months led to about 1.5 meters of erosion.
