The magnetic properties of 31 small samples from sites 332, 334, and 335 of Leg 37 DSDP were measured, and attempts were made to determine paleomagnetic field intensity. Values of paleointensity of 0.5 and 0.7 times the present field were obtained using one sample from site 332 and one from Site 335 respectively. All of the remaining samples proved unsuitable for paleointensity determinations owing to alteration on heating. This alteration is of two types: (1) destruction of maghemite, which reduces the magnetization of the samples, and (2) a process that markedly increases their thermal and saturation remanences and which may involve precipitation of new small magnetic grains out of glass. A 19 m thick layer at a depth of about 600 m in hole 332B, which appears to be a single unit on the basis of visual examination and chemical analysis of samples, contains a magnetic polarity transition. This may be due to a field reversal, or a partial reversal, while the unit was being implaced. Only samples from site 335 have a magnetization that can account for the surface anomaly by the remanence of the layers drilled.

Abstract. The interest in the role of the solar wind termination shock and heliosheath in cosmic ray modulation studies has increased significantly as the Voyager 1 and 2 spacecraft approach the estimated position of the solar wind termination shock. The effect of the solar wind termination shock on charge-sign dependent modulation, as is experienced by galactic cosmic ray Helium (He++) and anomalous Helium (He+), is the main topic of this work, and is complementary to the previous work on protons, anti-protons, electrons, and positrons. The modulation of galactic and anomalous Helium is studied with a numerical model including a more fundamental and comprehensive set of diffusion coefficients, a solar wind termination shock with diffusive shock acceleration, a heliosheath and particle drifts. The model allows a comparison of modulation with and without a solar wind termination shock and is applicable to a number of cosmic ray species during both magnetic polarity cycles of the Sun. The modulation of Helium, including an anomalous component, is also done to establish charge-sign dependence at low energies. We found that the heliosheath is important for cosmic ray modulation and that its effect on modulation is very similar for protons and Helium. The local Helium interstellar spectrum may not be known at energies
