Analysis of Marine Sediment to Explain Sea-level Rise in Paynes Creek National Park, Belize (2017)
DOCUMENT Citation Only Kurt Dilores. Heather McKillop.

Archaeological research in Paynes Creek National Park, Belize provides insight into environmental changes over time. Sea-level rise has affected coastal Maya settlements during both the Classic and Postclassic Periods. Marine sediment samples from five submerged Classic Period Maya sites were exported under permit to the Archaeology lab at Louisiana State University where the samples were analyzed using loss-on ignition and microscopic sorting. The results from loss-on ignition as well as...

Coastally Adapted: A Model for Eastern Coastal Paleoindian Sites (2020)
DOCUMENT Citation Only Shawn Joy.

This is an abstract from the session entitled "Love That Dirty Water: Submerged Landscapes and Precontact Archaeology" , at the 2020 annual meeting of the Society for Historical Archaeology. Predicting the cultural material typology of eastern coastal Paleoindians is a challenge due to sea-level rise since the LGM. In the Americas, archaeologists have identified only a handful of unequivocal coastal Paleoindian sites. The location of these sites are on the west coast of the Americas, where...

Holocene Transformation of San Francisco Bay and Transbay Man Site Stratigraphy (2015)
DOCUMENT Citation Only Jack Meyer.

San Francisco Bay was created by post-glacial sea-level rise during the span of prehistoric human occupation. The Bay is the single largest Pacific estuary in the Americas (4,160 square kilometers) and is the outlet for California’s largest freshwater drainage system that carries 40% of the state's runoff. The earliest known evidence of widespread human use of the estuary or tidal resources in the Bay Area first appears at shell midden sites located around the Bay in the middle Holocene...

Risk Assessment of Archaeological Sites Using Lidar: Sea level Rise Modeling at Jamestown Island, VA (2017)
DOCUMENT Citation Only Robert Chartrand.

Jamestown Island contains low-lying terrain with archaeological sites, known and unknown, threatened by sea level rise.  Using data acquired from the United States Geological Survey (USGS), a Digital Elevation Model (DEM) was created using a Light Detection and Ranging Remote Sensing technique (LIDAR) to identify cultural sites and assist in planning for cultural remediation. Four scenarios of sea level rise modeling were created based on historic trends and projected environmental events...

Sea-level Rise at an Inundated Ancient Maya Salt Work: New Information from the Eleanor Betty Site, Paynes Creek National Park, Belize (2017)
DOCUMENT Citation Only Valerie Feathers. Heather McKillop. E. Cory Sills. Rachel Watson.

Underwater excavations were performed at Eleanor Betty in 2013 to assess sea-level rise, map preserved wooden architecture, and investigate the inundated shell midden associated with the site. A total of 39 sediment samples were subjected to loss-on ignition (the burning of sediment to obtain the percent of organic matter present) and microscopically sorted in order to identify and analyze organic and inorganic matter. All samples were high in organic content and contained an abundance of fine...

The Trouble With The Curve: Reassessing The Gulf of Mexico Sea-Level Rise Model (2018)
DOCUMENT Citation Only Shawn Joy.

During last glacial episode, a massive amount of water was locked within ice sheets, resulting in a reduction in global sea-levels by 134 meters. The reintroduction of freshwater into the oceans radically changed global sea-levels and littoral landscapes. Over the last 20,000 years, approximately 15-20 million km2 of landscape has been submerged worldwide. Sea-level rise explains the rarity of glacial period coastal archaeological sites. Understanding Florida’s Paleoindians’ interactions with...
