Helium isotopic composition of hydrothermal fluids from the Manus back-arc Basin, Papua New Guinea
We present isotopic analysis of helium in hydrothermal fluids from the Manus back-arc basin, collected during the French-Japanese Manusflux and Manaute cruises in 1995 and 2000, respectively. The helium isotope composition of the fluids is comparable to that measured elsewhere in similar subduction environments, with 3He/4He values (7.4 to 7.9 Ra) slightly lower than typical MORB values, except...
متن کاملPopulation structure of Bathymodiolus manusensis, a deep-sea hydrothermal vent-dependent mussel from Manus Basin, Papua New Guinea
Deep-sea hydrothermal vents in the western Pacific are increasingly being assessed for their potential mineral wealth. To anticipate the potential impacts on biodiversity and connectivity among populations at these vents, environmental baselines need to be established. Bathymodiolus manusensis is a deep-sea mussel found in close association with hydrothermal vents in Manus Basin, Papua New Guin...
متن کاملThe CO2-He-Ar-H2O systematics of the Manus back-arc basin: Resolving source composition from degassing and contamination effects
We report new stepped heating He, Ar, CO2 and water data on a petrogenetically diverse suite of lavas from the Manus back-arc basin, where a plume component has previously been identified. The aim of this study is to evaluate the superimposed effects of degassing and contamination in order to identify mantle source characteristics. CO2 abundances and carbon isotopes in both the vesicle ([CO2] u...
متن کاملType 1 diabetes mellitus in children in Papua New Guinea.
Anecdotal and published information suggest a low incidence and prevalence of type 1 diabetes in Papua New Guinea (PNG). Incidence and prevalence were followed prospectively from July 1996, using the PNG Paediatric Surveillance Unit (PSU). No children were receiving insulin in Papua New Guinea at the start of the period. Over the next 4.5 years, 8 cases were reported--an annual incidence of 0.0...
متن کاملDonovanosis in Papua New Guinea.
Clinical and epidemiological observations on 87 cases of donovanosis seen at Port Moresby General Hospital are presented, with detailed reports of three cases in which the disease was more severe. The circumstances of infection described were consistent with venereal transmission. Chloramphenicol and gentamicin were effective in curing the disease, while streptomycin was found to be ineffective...
