A Bronze Age Flint Industry from a Barrow Site in Micheldever Wood, Hampshire

AbstractThe excavation of a multi-tumped oval barrow led to the discovery of a post-barrow flint industry, which utilized flint nodules incorporated in the mounds, thus damaging the original profile of the monument. 16,030 pieces of worked flint were recovered, 10,539 from the industrial levels. The material was analyzed by computer making use of programmes already developed for daily use by the M3 Archaeological Rescue Committee.

A Barrow Cemetery of the Second Millennium B.C. at Tallington, Lincolnshire

SummaryThe excavation examined two barrows which formed part of a cemetery in use towards the middle of the second millennium BC. The smaller barrow (Site 17) contained a large pit-grave in which successive inhumation burials had been made associated with a long-necked beaker, bronze earrings and a flint knife. The larger barrow (Site 16) began as a small mound covering an inhumation burial with a Food Vessel. Four stake circles were added following a second inhumation burial and the original mound was enlarged on two subsequent occasions. Many features of the barrows find their closest parallels in Yorkshire.

CO 2 Exchange over the Alaskan Arctic Tundra: Meteorological Assessment by an Aerodynamic Method

Photosynthesis, which incorporates solar energy into stored chemical energy, is the foundation of ecosystem function. Kinetic characterization of primary productivity is therefore paramount to understanding energy partition and flow within an ecological system. The International Biological Program U.S. Tundra Biome has directed an integrated research programme in the Arctic Tundra near Barrow, Alaska since 1970. Objectives have included understanding the structure and function of the tundra ecosystem. The central role played by primary producers of the system has resulted in considerable research to characterize photosynthesis and related processes. Independent and complementary approaches were needed to measure the seasonal incorporation of as a function of environmental parameters. The methods used at the Barrow site included the harvest method (Dennis & Tieszen 1972), in situ measurement of photosynthesis by cuvette techniques (Tieszen 1973), rates of CO2 incorporation (Tieszen, Johnson & Caldwell 1972), and a micrometeorological determination of exchange rates by an aerodynamic method which forms the subject of this paper. In comparison with other methods for assessing primary productivity, the aerodynamic method has some desirable attributes. It is non-destructive and is sensitive to immediate environmental conditions, and it measures exchange by the whole community so that extrapolation from measurements on individual plants is not required. In effect this approach integrates primary producer and decomposer components of an ecosystem. Some of the deficiencies of the method will become evident below.
