SCLEROCHRONOLOGY
The Sclerochronology Service specializes in the chronological dating of calcified tissues (otoliths, scales, shells, etc.) using both seasonal and daily marks, in the validation of the periodicity of these marks through direct and indirect methods, and in the analysis of the elemental composition of tissues (trace elements and isotopes) using various spectrometric techniques.
Currently, Sclerochronology is projected as an interdisciplinary science with various applications: (i) paleoclimate reconstruction, (ii) climate and environmental change, (iii) physical and biological studies, (iv) presence of contaminants and their effects, and (v) applications in studies of fisheries resource management and conservation.
The Service, included in the CSIC Catalogue of Scientific and Technical Services, employs a specialized technician in microchemistry and dating. It also has all the necessary materials and infrastructure for the initial preparation of samples (extraction, embedding, cutting, and polishing) in ultraclean conditions, and optical and digital equipment for their observation. Two distinct Provisions (Dating and Microchemistry) are offered, each with various Variants, although the Service is open to exploring new methodologies and developing new analysis protocols. An initial consultation is conducted to determine the most appropriate methodology for the study’s objectives, and standardized protocols are applied for sample processing and results analysis; additionally, participation in the writing of scientific articles is possible.
The Service is available internally to researchers at IMEDEA (CSIC-UIB) or other CSIC centers, as well as externally to other AGE entities, OPIs, Spanish universities, and private or foreign entities, with differentiated rates applied as appropriate.
