| Abstract | Pinus thunbergii trees growing on Pacific coastal sand dunes in Japan were immersed by the tsunami that followed the Great East Japan Earthquake on 11 March 2011. Even trees that survived direct physical damage began to die during the following summer, probably because of the physiological stress of salt water immersion. The objectives of this study were to analyze the relationship between the carbon and oxygen isotope values (δ$^{13}$C and δ$^{18}$O, respectively) of P. thunbergii tree-ring cellulose and the effects of salt water immersion caused by the tsunami. Pinus thunbergii trees were sampled in Yamamoto, Miyagi Prefecture, and in Misawa, Aomori Prefecture. Each tree-ring that formed between 2008 and 2012 was sliced into four to eight equal subdivisions, and the isotope values were analyzed at a high time-scale resolution. Tree rings that were immersed in seawater from the tsunami had higher δ$^{13}$C values in the earlywood that formed in the spring following the tsunami than those formed prior to the disaster. This increase in δ$^{13}$C values was likely caused by osmotic stress from root immersion in salt water. We did not observe a clear change in tree-ring δ$^{18}$O values after the tsunami. This lack of variance might have resulted from the post-photosynthetic exchange of carbonyl oxygens with non-$^{18}$O-enriched xylem water. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
