GEOBASE is a unique multidisciplinary database supplying bibliographic information and abstracts for development studies, the Earth sciences, ecology, geomechanics, human geography, and oceanography. The database provides current coverage of almost 2,000 international journals, including both peer-reviewed titles and trade publications, and provides archival coverage of several thousand additional journal titles and books.
GEOBASE is unequalled in its coverage of international literature of the core scientific and technical periodicals. Papers are selected, read, and classified using a unique classification scheme that is versatile and updated annually to adapt coverage to current research trends. The material covered includes refereed scientific papers; trade journal and magazine articles, product reviews, directories and any other relevant material. GEOBASE has a unique coverage of non-English language and less readily available publications including books, conference proceedings and reports, making this the best resource available for multidisciplinary searches of international literature. The content crosses over subject, language, and cultural boundaries, providing a unique research tool to users.

|/AB||Pollen records across parts of Ireland, England and northern Scotland show|
|a dramatic collapse in Pinus pollen percentages at approximately 4000|
|radiocarbon years BP. This phenomenon has attracted much palaeoecological|
|interest and several hypotheses have been put forward to account for this|
|often synchronous and rapid reduction in pine from mid-Holocene woodland.|
|Explanations for the 'pine decline' include prehistoric human activity,|
|climatic change, in particular a substantial increase in precipitation|
|resulting in increased mire wetness, and airborne pollution associated with|
|the deposition of tephra. Hitherto, one largely untested hypothesis is that|
|mineral deficiency could adversely affect pine growth and regeneration on|
|mire surfaces. The discovery of pine-tree remains (wood pieces, stumps and|
|trunks) within a peat located at Cadogan's Bog on the Mizen Peninsula,|
|southwest Ireland, provided an opportunity to investigate the history of|
|Pinus sylvestris and also to assess the importance of mineral nutrition in|
|maintaining pine growth on mires. Pollen, plant macrofossils, microscopic|
|charcoal and geochemical data are presented from a radiocarbon dated|
|monolith extracted from this peat together with tree ring-width data and|
|radiocarbon dated age estimates from subfossil wood. Analyses of these data|
|suggest that peat accumulation commenced at the site around 6000 years BP|
|when pine was the dominant local tree. Thereafter Pinus pollen percentages|
|diminish in two stages, with the second decline taking place around 4160|
|+/- 50 years BP. Concomitant with this decline in Pinus pollen, there is a|
|noticeable, short-lived increase in wet-loving mire taxa and a decrease in|
|the concentration of phosphorus, potassium, magnesium, calcium, sodium,|
|iron and zinc. These results suggest that increased mire surface wetness,|
|possibly the result of a change in climate, created conditions unsuitable|
|for pine growth c. 4000 years BP. Mire surface wetness, coupled with a|
|period of associated nutrient deficiency, appears to be a possible|
|explanation for a lack of subsequent pine-seedling establishment for most|
|of the later Holocene.|
