An estuarine tidescape of production
Terrestrial laser scanning (TLS) provides a means of rapid and highly accurate survey of archaeological excavations and structures at landscape scales, and is particularly valuable for documenting tidal environments. Here, the authors use TLS to record tidal fixed fishing structures and a tide mill within the Léguer Estuary at Le Yaudet, in north-west France. As part of a comprehensive resource-exploitation system, the early medieval (sixth to ei…

Effect of sympathectomy and sympathectomy/vagotomy on reduction of food intake by cholecystokinin-8 and 33
Life by the River
This paper describes the development of a prehistoric landscape by the river Nene at Grendon Lakes, partly revealed in the 1970s and partly during excavations in 1998 and 2001, which are reported in full. Two major phases of archaeological activity are evident, one interpreted as Neolithic–Early Bronze Age, the other as Iron Age. The gap between these is bridged by an environmental sequence reconstructed with the aid of a pollen core from an adja…
Intra-Annual Variability of the Radiocarbon Content of Corals from the Galapagos Islands
We report AMS 14 C measurements on subannual samples of coral from the Galapagos Islands that span the period, 1970–1973. Both the major 1972 El Niño/Southern Oscillation event and intra-annual changes in regional upwelling of 14 C-depleted waters associated with alternation of surface-ocean current patterns are evident in the record. Our data show that the corals preserve a detailed record of past intra-annual variations of the 14 C content of s…
Radiocarbon AMS Dating of Pollen Extracted from Peat Samples
We present 14 C AMS measurements and discuss the extraction procedure used on pollen extracted from peat samples. Microscopic examination of the extracts shows that the procedure is sufficient to remove most non-pollen materials and results in an extract that is composed predominantly of pollen. The 14 C dates that we obtained for pollen extracts from peat samples associated with the Mazama Ash layer are consistent with the range of bulk-sample d…
Improved Collagen Extraction by Modified Longin Method
A re-evaluation of the Longin collagen-extraction method shows that a lower reflux temperature reduces degradation of protein (“collagen”) remnants. This allows additional purification through ultrafiltration to isolate the >30kDalton fraction of the reflux product
Accelerator Radiocarbon Dating at SFU
The Simon Fraser University accelerator mass spectrometry (AMS) facility has now been in semi-routine use since the beginning of 1985. The advantages and limitations for 14 C dating are described
