ARCHAEOLOGICAL SAMPLING AND SURVEY
Fieldwalking/ Pedestrian Survey
Divide study area into transects along grid lines, plant flags whenever you find
something; colour corresponds to what you find
Situational differences: direction of plough,scars, forest cover, weather, experience of
surveyors
Determining “sweep width” is based on numerous aspects: skill, familiarity with local
artifacts, conditions, etc.
Why is Sampling Needed?
Can we safely assume that an area can be surveyed completely?
What are the limits to survey strategy?
Cost?
Time?
Access?
Rationale
Artifacts found
Literary Sources
Oral Sources
Local Knowledge
Previous Surveys
Previous Excavations
Aerial Photography/Google Earth
Is there a single best method for selecting a sample or should your sampling strategy be
influenced by your questions?
A: No single answer; depends on time, money, type of development going on
Hunter-Gatherer Mobility: Logistical (Collectors)
Hunter-Gatherer Mobility: Residential (Foragers)

ANT200 LECTURE 6
Carbon Dating:
Half life of 5,730 years. In a sample of Carbon 14, half of the atoms will decay to a more
stable carbon isotope over a period of exactly 5,730 years. In other words, 1% of the
sample will decay every 83 years
AMS (Accelerator Mass Spectrometry): Directly measures isotopes, shooting atoms of
carbon at a very high velocity, sorts by mass and counts how many atoms
Issue with radiocarbon dating: counting the atoms, preparing the samples so that they
are clean
But… although the ratio of C14 to stable isotopes is constant at a given moment in
time...it is not constant through time...so C14 ages must be calibrated
Calibration curves developed by dating tree rings of known age
BUT THEN IT ALL COMES BACK TO STRATIGRAPHY AND CONTEXT…
Fairy Circles
Areas in semi-desert where there are circular clearings in the grass
Causes: could be termites who strip away grasses,
Domestication: A relationship between humans and plants and animals.
Technology: The tools used for daily tasks
Sedentism: The development of a ‘constructed landscape’.
