18O analysis of Littorina littorea shells from Ferriter¹s Cove, Dingle Peninsula: preliminary results and interpretations
No full textSeasonality studies can facilitate identifi cation of variability in the purposes for which Mesolithic sites
were occupied and relations among forager mobility, economy, and society. Analyses of fi sh remains at the
site of Ferriter’s Cove have produced evidence for occupation during the summer half of the year. Our
study – an oxygen isotope analysis of seven Littorina littorea (periwinkle) shells from a pit feature
(F488; c. 5200–5350 BP) at Ferriter’s Cove – complicates this pattern by introducing preliminary
evidence for occupation during the winter half of the year as well. These results, when corroborated by
further research, will inform the development of explanatory models for Later Mesolithic settlement and
mobility and, because of F488’s late date, those for social change during the last quarter of the Later
Mesolithic and the transition to Ireland’s Neolithic
UK Climate Projections science report: Marine and coastal projections
No full textThe UK has a long maritime heritage and the marine and coastal environment continues to play an important role in the national culture and economy. United Kingdom waters cover an area approximately three times greater than its land and the UKs coastline is the longest in the EU. Over half a million people are directly employed in maritime activities (e.g. shipping, tourism, fisheries)
and 95% of international trade into and out of the UK passes through its sea ports (EU Maritime Policy Facts and Figures United Kingdom). In 2004 sea-fish with an initial value of £513 million were landed by the UK fishing fleet. It has been estimated that the total turnover of the marine sector in 1999–2000 was just under £70 billion, of which almost £40 billion was due to Oil & Gas and Leisure. Beyond the direct maritime economy the
UKs marine environment provides a number of important goods and services to the UK. Along the coast, more than £150 billion of assets are estimated to be at risk from flooding by the sea, with an excess of £75 billion at risk in London alone (estimated from Halcrow, 2001)
A Meteorological Data Journal
No full textThe Overlay Journal Infrastructure for Meteorological Sciences (OJIMS) project developed the mechanisms and evaluated the business model that could support a new Journal of Meteorological Data. This work was supported by the Joint Information Systems Committee and the National Centre for Atmospheric Science. The work of the OJIMS project is conducted by a partnership between the Royal Meteorological Society, the British Atmospheric Data Centre and the University of Leeds.
This poster describes the results of a survey of scientists conducted by the Royal Meteorological Society to assess users’ views of the creation and operation of the proposed Journal of Meteorological Data. It also describes reactions to supervised run-throughs of a demo of the Journal of Meteorological Data. The survey and demo were conducted at the NCAS Conference in Bristol on 8-10 December 2008.
The concept behind the Journal of Meteorological Data is to extend the scientific discipline of peer review to data. It received a strong positive response in the survey with 69% agreed that they would like to access data from an RMetS Journal. 67% agreed that they were more likely to deposit their data in a data centre if they could obtain academic credit through a data journal. Almost all respondents were users or creators of meteorological data of some kind. The only existing data journal in this area is aimed at all environmental sciences and 91% of respondents had never heard of it
Investigations of profiles of vertical velocity skewness and sources of layers of strongly positive skewness as measured by Doppler lidar during COPS
No full textThe Convective and Orographically-Induced Precipitation Study, COPS, was conducted in the Black Forest region of Germany during the summer of 2007. Its aim was to advance the quality of forecasts of orographically induced convective precipitation by 4D observations and modelling. From the 13th June to the 16th August 2007, the Universities’ Facility for Atmospheric Measurement (UFAM) 1.5 micron scanning Doppler lidar, operated by the University of Salford, was deployed at Achern, Baden-Württemberg, Germany, in order to take part in the extensive COPS observation campaign. The University of Salford lidar system measures radial wind and aerosol backscatter from 105 m above the surface to the top of the boundary layer. Profiles of horizontal wind velocity are shown; these being derived from performing azimuth scans of 5 minute duration, approximately every 30 minutes. Between azimuth scans, the lidar pointed vertically. Profiles of vertical velocity, its variance and skewness are also shown. Knowledge of vertical velocity skewness is important as it can help understand the structure and origin of turbulent convection in the boundary layer. The skewness of vertical velocity can provide a measure of the asymmetry in the distribution of vertical velocity perturbations within the atmospheric boundary layer (ABL). In previous studies, under fair-weather conditions, when the ABL is heated from below, skewness profile tends to be positive throughout the ABL, while under cloudy conditions, the skewness profile can be affected by cloud processes and therefore predominantly negative. The behaviour of the boundary layer is investigated using data from the Salford University Doppler lidar, microwave radiometer and automatic weather station. In this paper, selected cases are compared and the similarities and differences are noted. Investigations of possible causes of layers of positive and negative skewness are presented, along with intercomparisons with radiosonde ascents from the Achern site
