MICRONESIAN JOURNAL OF THE HUMANITIES AND SOCIAL SCIENCES Vol. 4, nº 1 Dry Season Issue June 2005 TRADITIONAL AND NINETEENTH CENTURY COMMUNICATION PATTERNS IN THE MARSHALL ISLANDS Dirk HR Spennemann Institute of Land, Water and Society, Charles Sturt University In the atoll world of Micronesia, any traditional communication between the populations within an atoll and especially between atolls relied on sea voyages by canoe. This paper considers the situation in the Marshall Islands, a group of atolls arranged in two parallel chains. The paper sets out the (re-)construction of communications networks based on graph theory and then provides a discussion of the evidence on communications in the early Marshall Islands. This draws together data as diverse as traditional stick charts, known voyages and their durations, as well as linguistics, epi- demiology and biogeography. Based on a combination of these data a network model is proposed. Micronesians have a long and well-deserved This study will examine the communication reputation for long-distance open sea voyaging patterns in the Marshall Islands during the in canoes that are deemed small by European eighteenth and nineteenth centuries.
