This has increased resident and tourist populations, which has heightened the demand on the island’s groundwater supply. Another threat to the future of Rapa Nui is pollution of its freshwater resource. Three possible pollution sources are seawater intrusion, the Orito Landfill, and the lack of a septic waste system. Seawater intrusion is a potential threat for Rapa Nui because the aquifer becomes shallower near the coast and groundwater pumping occurs near the coast. The unlined Orito Landfill sits atop a groundwater divide, increasing the potential for chemical compounds to disperse in various directions. The lack of a centralized septic waste system also poses a growing threat from potential seepage into the groundwater supply. Increased understanding of the hydrogeologic conditions and sources of groundwater pollution need to be a priority for the government of Chile and the municipality of Rapa Nui to help sustain the fresh groundwater supply. This research focuses on the groundwater conditions in the southeastern part of the island near the town of Hanga Roa, where most residents live and where groundwater is the sole source of potable water. This report attempts to combine general hydrogeologic knowledge with observed data from various sources in order to create a baseline assessment of the current groundwater situation. Current knowledge of groundwater pumping wells and pollution sources needs to be expanded in order to manage the water supply sustainably for future generations. An investment in a hydrologic monitoring program, compatible with improved waste management, would help lead to a safe, reliable drinking water source for the people of Rapa Nui.Item Temple renovations, aggregate marae, and ritual centers: the ScMo-15 Complex, Lower Amehiti District, ‘Opunohu Valley, Mo‘orea (Society Islands)(2013-10-01) Kahn, Jennifer G.This article describes test excavations of two marae (temples) in the lower Amehiti sector of the ‘Opunohu Valley, Mo‘orea. Recent projects in the ‘Opunohu Valley have dated temple sites in the upper reaches of the Tupauruuru District, while those resting in lower valley elevations, where residential settlements and ritual complexes tend to be most frequent, have been lacking. The test excavations described here were designed to recover data relating to marae construction sequences and to recover wood charcoal for radiometric dating. The results offer important evidence concerning the only aggregate marae center found in the Amehiti District. These new data require a slight modification of interpretations of ‘Opunohu Valley settlement patterns and their relationship to status and hierarchy in this highly productive windward valley context.Item The paintings of Ana Kai Tangata cave, Easter Island (Rapa Nui)(2013-10-01) Lee, Georgia; Horley, PaulBased on our detailed analysis of the historic photographs and watercolors of Ana Kai Tangata cave, we have made a tentative reconstruction of the entire painted panel as it might have been in the beginning of the 20th century, featuring a larger number of birds. Surprisingly, there are numerous depictions of historic ships – second only to the birdman village of ‘Orongo – suggesting that at a certain time in history, the islanders may have considered the European visitors as messengers from the other world, arriving and disappearing to the ocean in a similar seasonal cycle as the migrating birds. This parallel may have been reinforced by the seasonality of ship callings at Easter Island, which occurred with a considerable prominence around the Austral spring and autumn, approximately at the time of the birdman ceremony and half a year after it.Item New insights in conservation of Sophora toromiro (Phil.) Skottsb., emblematic species of the South Pacific(2013-10-01) Espejo, Jaime; Rodriguez, FranciscoThis paper presents advances in a conservation and reintroduction program of Sophora toromiro (Phil.) Skottsb. A status quo of specimens growing in Chile is compiled and propagation of germplasm is performed by inter-specific grafts (scion and rootstock are different species). To date, over 300 grafts are ready for the establishment of a multipurpose Clonal Seed Orchard (CSO) with a germplasm collection based on three lines known as the National Botanic Garden of Viña del Mar (JBV), Goteborg (Got) and Titze (Tit). Additionally, the first controlled pollination seeds were obtained in order to understand basic aspects of reproductive biology. Activities and a work program to ensure gradual recovery of S. toromiro in Rapa Nui are identified. This is the second documented experience of rescuing a species listed as extinct in the wild by a traditional but effective technique in the field of horticulture, the first being made with Molokai koki‘o (Kokia cookei O. Deg).Item Letter to the Editor(2013-10-01) Lee,Georgia
