New Evidence

The number of Mesolithic structures known in Britain has significantly increased since 2000, providing new opportunities for economic and social interpretations of this period. We describe a further structure, represented by features from the Mesolithic site of Criet Dubh, Isle of Mull. We compare the inferred Criet Dubh structure to other Mesolithic structures from Britain, notably those described as ‘pit-houses’. We then consider the implications of the radiocarbon dates from such structures for the tempo of occupation and past settlement patterns. While the use of Bayesian analysis of radiocarbon dates has encouraged interpretations of prolonged occupation and sedentism, we propose alternative interpretations with patterns of intermittent occupation for Criet Dubh and the pit-houses, involving their re-use after extended periods of abandonment within a sparsely populated landscape. The ability to debate such interpretations reflects the transformation in Mesolithic research made possible by the discovery of such structures, the use of multiple radiocarbon determinations, the application of Bayesian analysis, and the exploration of associations between cultural and environmental change. These developments have made the Mesolithic a particularly innovative period of study.

Sessile Organisms

The seafloor beneath floating ice shelves accounts roughly a third of the Antarctic’s 5 million km2 of continental shelf. Prior to this study, our knowledge of these habitats and the life they support was restricted to what has been observed from eight boreholes drilled for geological and glaciological studies. The established theory of sub-ice shelf biogeography is that both functional and taxonomic diversities decrease along a nutrient gradient with distance from the ice shelf front, resulting in a depauperate fauna, dominated by mobile scavengers and predators toward the grounding line. Mobile macro-benthic life and mega-benthic life have been observed as far as 700 km under an ice shelf. New observations from two boreholes in the Filchner-Ronne Ice Shelf challenge the idea that sessile organisms reduce in prevalence the further under the ice you go. The discovery of an established community consisting of only sessile, probably filter feeding, organisms (sponges and other taxa) on a boulder 260 km from the ice front raises significant questions, especially when the local currents suggest that this community is somewhere between 625 km and 1500 km in the direction of water flow from the nearest region of photosynthesis. This new evidence requires us to rethink our ideas with regard to the diversity of community types found under ice shelves, the key factors which control their distribution and their vulnerability to environmental change and ice shelf collapse.

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.
