Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2-3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological rem...

Magnetic properties are sensitive paleoenvironmental proxies frequently used in studies of loess paleosol profiles. Understanding precisely the magnetic recording soil responses to environmental and climatic changes needs combining pedologic data geophysical proxies. Here we present a new high-resolution study 450 ka old loess-paleosol profile from low Danube area at Kaolinovo (NE Bulgaria). Th...

Magnetic susceptibility measurements play a key role in Quaternary studies. proxies, such as low field and frequency-dependent magnetic susceptibility, are widely applied the reconstruction of terrestrial paleoclimate, e.g., study loess-paleosol successions. In general, interpretation loess signals is based on two commonly accepted models: pedogenic enhancement wind-vigour models. However, ther...
