(2) Food Chains and Possible Radionuclide Pathways to Man The study and evaluation of trophic pathways in the atoll ecosystem that ultimately lead to man, may provide significant information for the wisest and best use of the atoll'’s resources in order co block or minimize radionuclide uptake by man. (3) Man's Place in the Atoll Ecosystem To study those problems that will lead to a better utilization of the human and natural resources of the marine and terrestrial environment for the benefit of atoll inhabitants is a goal or mission which needs emphasis although its essence is incorporated in (1) and (2) above. (4) Support to Investigators MPML provides scientists with laboratory facilities, vessels, technical and logistical support, and advice and assistance for studying the unique characteristics of the atoll ecosystem. In addition, MPM maintains natural history records, physical descriptions, a scientific library, a reference collectionof the local biota, and a weather station to facilitate specialized research efforts of visiting investigators. The MPML monitors levels of radioactivity when directed by DOE, and routinely records oceanographic and atmospheric phenomena to support studies aimed at a better understanding of long-range environmental trends. All of the above missions are performed with due regard for the social, economic and cultural significance of the laboratory's presence in the
