On the origin of drift materials in the Marshall Islands

Abstract

The oceanic dispersal of plants and animals has been the focus of studies ever since organized natural history started in the Pacific, and the dispersal of terrestrial by sea rafting has been given due consideration. The finding of drift materials such as glass floats, tree trunks and seeds, is a common occurrence on the shores of Pacific Islands, but in most cases the origin of such material is unknown or at least equivocal. Thus while the principle of sea rafted dispersal is known and reported at length, there is a need to document those occasions where positive proof of origin can be furnished.
