Abstract
Seven piston cores between 4 and 11 m in length were taken from McBeth, Itirbilung, Tingin, and Cambridge fiords and from Frobisher Bay, Baffin Island. The sediments consist of massive, laminated, and bioturbated muds, alternating silt and sand beds, or discrete and beds. Ice-rafted sediments occur throughout most cores. Mica, quartz, and feldspar are the dominant clay-sized minerals. Radiocarbon control on core chronology is limited but suggests that all cores date from the last 10,000 yr. Sediment accumulation, uncorrected for density, varies between 5 and 0.25 m ka super(-1). The sampling interval for paleomagnetic purposes varied between 3 and 5 cm providing a time-specificity of between 6 and 200 yr per sample. Studies of both natural remnant magnetization (NRM) and postdepositional detrital remnant magnetization (PDRM) indicate that, in general, these sediments are suitable for paleoinclination and paleodeclination studies.
