In November 1988, Gotland University College started a new archaeological research project on the Trobriand Islands, Papua New Guinea. Sixteen Swedish archaeologists and osteologists carried out excavations and osteological analyses at newfound sites on the northern part of Kiriwina Island. The aim of the project is to study the introduction and subsequent cultural development of the Trobriand culture (c 1000-1500 AD). 8 contributions are published here, including surveys, excavation reports, lithics, ceramics, oral traditions, climate and culture.
