What does dendrochronologist do?
Dendrochronologist measures the creation of constantly expanding circles of tree rings in tree trunks as an annual phenomenon of growth. Although this occurs only in some tree species and varies depending on the climate, it is considered an accurate means of dating past events. It is an area of science that is often used in climatological studies of botanists and foresters, as well as in the field of human archeology.
The duties of a dendrochronologist include collecting many samples of tree rings data from specific climatic areas and tree species. These rings reflect the amount of growth that the tree undergoes during the standard growing season. As a result, the tree rings are more pronounced in trees that have a sleeping period in winter, and it is not an effective method of dating with tropical species that do not live in different seasons.
In order to achieve accurate results of dating, samples of růThe tree ring is taken from the region and graphs by computer to create a precise reference set of data to determine changes in climate. This includes the collection of samples of simultaneous growth of the tree ring and work on, and in time towards the early stage of the ripening of the tree, as well as collecting data on tree rings from old beams used in buildings and fossilized wood or protocols preserved from decomposition in peat peat. Worldwide associations, such as the International Tree Data Bank, which are maintained in the US by the National Ocean and Atmospheric Administration (NOAA), use large databases of tree ring data based on stored physical samples to reconstruct changes in the previous climate of different regions.
Exploring the past in dendrochronological work, however, can only be taken so far. The oldest living trees are Bristlecone pine, with the ability to survive for 5,000 years and some living up to 9,000 years in a narrow range of habitats for species throughout the western north.Extremely old specimens are rare and are not used for trees analysis, although preserved beams from other tree species that have been used in the construction of the human structure can be traced back 4,000 to 5,000 or more years around the world. The Sheffield Dendrochronology laboratory in the UK has created more than 200 reference chronology of tree ring data in the main sequence, which extends back to 5,000 BC, and also covers the medieval period in Europe.
The research area of dendrochronology has an application in monitoring social and cultural patterns along with those of natural sciences, because tree rings are often taken from wooden artifacts. Rings can maintain the effects of air pollution on growth cycles as a by -product of industrial processes. As a result, the potential for describing the work of the dendrochronologist, which can bridge historical research in many fields.
natural formulas of changes in botany, biology or climatology such as those that are a wayENY wealthy glaciers, ice ages, volcanic activity or changes in the availability of surface water and precipitation patterns for a particular area affect the growth of trees. Entomologists who focus on the study of insect populations may also have dendrochronologists, because certain types of insects such as West Spruce Budworm can suppress the growth of trees. However, dendrochronologist not only not only catalog effects in the past; The dendrochronologist deals with a long reach of the changes recorded in tree groups, so that the past can also be a key indicator of trends that may occur in the future.
