This study presents new evidence for long-term variability in the late Holocene North American Monsoon (NAM), Pacific coast of Mexico. We have carried out a rock magnetic study on two deep-sea sediment cores from the Pacific coast Pescadero Basin. Th

A comparison of late-Holocene hydrologic variability in California: Regionality of multi-decadal to centennial-scale droughts

Autor: Steve Lund, Larry Benson, Ellen Platzman

Publikováno v: The Holocene. 32:735-744

This study compares the paleohydrologic variability in two California regions over the last 2000 years – Sierra Nevada region and southern California region. Both regions show significant and reproducible proxy evidence for multi-decadal wet/dry in

The Miocene Oxaya Formation, exposed along the western Andean slope in northern Chile, represents one of the largest ignimbrite provinces on earth. In this study, magnetic fabric data were acquired from a ~ 1-km-long core drilled vertically through a

Publikováno v: Marine Geology. 404:147-157

We have studied the rock magnetic characteristics of 31 multicores and 7 gravity cores from deep-sea sediments of the distal Amazon Fan and Demerara Abyssal Plain. This study has permitted us to delineate the space/time pattern of Holocene physical s

Paleomagnetic chronostratigraphy of late Holocene Zaca Lake, California

Autor: Steve P. Lund, Ellen Platzman

Publikováno v: The Holocene. 26:814-821

We have developed a paleomagnetic secular variation (PSV) record from Zaca Lake, California, that spans the last ~3200 years. The record is derived from detailed (2 cm) sampling of core 09-1C, which is 873 cm in length. The paleomagnetic remanence is
