Funds are being provided for a high-resolution geomagnetic paleointensity study of U-channel samples from ODP Leg 129, Site 769 in the Sulu Sea. A pilot study confirmed the exceptional magnetic quality of these sediments and demonstrated that the site is free of drilling-induced mangetic overprint or storage diagenesis that effects paleointensity. Samples also preserve millennial scale record and have excellent stable-isotopic stratigraphy. The study will allow a detailed understanding of the temporal evolution and high-rgrequency variability of geomagneic paleointensity record of the Brunhes age.

目前正在提供资金，对苏禄海第769号地点大洋钻探计划第129航段的U通道样品进行高分辨率地磁古强度研究。 一项试点研究证实了这些沉积物的特殊磁性质量，并表明该网站是免费的钻井引起的磁性叠印或存储成岩作用，影响古强度。 样品还保存了千年尺度的记录，并具有良好的稳定同位素地层学。 该研究将使人们对Brunhes年龄地磁古强度记录的时间演化和高分辨率变化有一个详细的了解。
