Description
En este trabajo se analiza un sector del Humedal costero de la Bahía de Samborombón que fue ocupado por cazadores-recolectores-pescadores durante el Holoceno tardío. En una superficie aproximada de 5 km2, en un ambiente caracterizado por la presencia de canales de régimen estuarial, montes de tala y pastizal pampeano, se realizó un diseño de muestreo de carácter regional utilizando estadística bayesiana.
El muestreo tuvo por objetivo localizar la totalidad de las posibles ocupaciones en los montes de tala dentro del área. La incorporación de información previa al análisis posibilitó la determinación de la distancia entre puntos de muestreo con una mayor eficacia, minimizando el trabajo requerido para cubrir un área de grandes dimensiones, como así también el riesgo de pérdida de probables hallazgos. La realización de un muestreo probabilístico en un sector con baja visibilidad arqueológica, ha permitido en un tiempo razonable y a bajo costo contar con información sobre la ocupación del área y las características del registro arqueológico en relación a las tecnofacturas, y la posible distribución espacial de diferentes actividades.
In this paper we analyze a wetland section of the Samborombon Bay coast, occupied by hunter-gatherers-fishermen during the late Holocene. In an area of approximately 5 km2, characterized by the presence of channels of estuarine regime, tala forest vegetation and grasslands, we conducted a sampling design using Bayesian resolution. The sampling aimed to find all possible occupations in the area. Incorporating information prior to analysis allowed defining the distance between sampling points with greater efficiency, minimizing the work required to cover a large area, as well as the risk of loss of potential findings. We summarize the methodology used, provide the results of this sampling methodology and discuss the intensity of human space use. The applied methodology in a sector with low archaeological visibility allowed us to have information about human occupation of the area, the characteristics of the archaeological record and the probable spatial distribution of different activities, in a reasonable time and low cost.
