INKING RCHAEOLOGICAL ATA AT A ARGE CALE

Below: DINAA helps coordinate any site- or culturally-specific data sets, and will make them discoverable with public information, web-related collections, and citations to publications.

A: Analyses using DINAA linked datasets indicate about 30,000 archaeological sites are at risk given a 3m rise in sea level, likely to occur in one to two centuries given IPCC projections. Coordination of the research community through DINAA will provide better understanding of the damage and illuminate priorities for study.

B: Southeastern NRHP properties within 200km of the coasts. The distribution of recognized important resources, along with DINAA coordination of the research community, can help model potential effects of inland population migration.

(The Digital Index of North American Archaeology)AbstractA crucial challenge facing archaeologists is using the vast quantities of data we are generating for research, management, and public education. TheDINAA project provides online methods for linking non-sensitive archaeological data from a wide array of sources, to explore questions of human-environmental interaction at multiple geospatial and temporal scales, in the past, present, and future. A multi-institutional collaborative effort, DINAAprovides a framework for distributed linked open data initiatives in North American archaeology; promotes greater interaction between datagenerators, managers, and users; and helps promote a greater appreciation for archaeology among researchers, resource managers, and the generalpublic.

IntroductionThe Digital Index of North American Archaeology(DINAA) is a web hosted resource that deliversarchaeological site data through direct cooperationand partnership with SHPO site file managers,federal institutions, and THPO representatives.Open Source translational protocols, extensiveindexing, and URI minting allow integration ofdatasets from many different and incompatibledata sources in a single interface (Figure 1). Atpresent DINAA shares primary data from over340,000 archaeological sites in 15 states in easternNorth America.

DINAA archaeological site data were compiled incooperation with State Historic PreservationOffices in our partner states to demonstrate thefeasibility and research value of interoperatingstate-maintained site databases into a single, large-scale, freely-available archaeological dataset thatprotects sensitive site location information.

In this study, we used DINAA data to model theeffects of anticipated changes in sea level due toglobal climate change on cultural resources nearthe Atlantic and Gulf coasts. The sample isderived from nine coastal states represented byDINAA and a 200 km buffer from the EasternAtlantic modern coastline

Results show that projected sea level rise withinthe coming century, as well as in the centuriesafter, will result in the loss of a substantial portionof the record of both pre-Contact and historichuman habitation of the coastal margin of thesoutheast.

ADDRESSING A BIG DATA ISSUE WITH DINAA

Global climate change and rising sea levels are apressing environmental reality that archaeologistsmust address, both as cultural resource advocatesand as scientists with unique information abouthow past societies were affected by changingclimates.

The effects of sea-level rise and concomitanthuman population relocation on cultural resourcesare examined using a sample of nine statesencompassing much of the Gulf and Atlanticcoasts of the southeastern United States.

Projected sea level rise within the comingcentury, as well as in the centuries after, willresult in the loss of a substantial portion of therecord of both pre-Contact and historic humanhabitation of the coastal margin of the southeast.

Comparison of newly public DINAA data on“all” archaeological sites (A) with currentlyavailable public data from the National Registerof Historic Places (B) demonstrates the scope ofthe problem. Through coordination of existinginformation through DINAA, the archaeologicalcommunity can begin tackling many emergentissues.

Publically available data from NOAA, USGS,and FDA allow modeling at multiple scales andprecision. For this study elevation data werespatially joined with the archaeological data toestimate archaeological sites potentiallyimpacted.

Figure 2, below, shows the coastal land area thatis within 5 meters of current sea level. Many ofthese high risk areas also represent modernpopulation centers, which will compound thestrain on infrastructure in the event of emergencyreclamation (Figure 3).

Given a 1 meter rise in sea-level, which in manyprojections is likely within a century, largenumbers of historic properties will be lost,including over >13,000 historic and prehistoricarchaeological sites (Table 1).

Over 1000 properties currently designatedeligible for inclusion on the National Register ofHistoric Places (NRHP) will be effected,encompassing both archaeological sites, standingstructures, and other cultural property types(Table 2).

Projections from this region alone, indicate thelikely impact of climate change on the record ofthe human past.

Every effort should be directed to minimizing andmitigating these losses, as well as planning forincreased destruction of heritage resources inareas where resettlement occurs.

Since DINAA provides stable URIs, and the otherdata used in analysis are public, this model canbe produced and reproduced efficiently, and canbe adopted by agencies and institutions withoutprohibitive cost that often accompanies predictivemodelling projects.
