Interplay of the Indian summer monsoon and intermonsoon precipitation in Sri Lanka due to ITCZ migration during the last 80000 years.

Precipitation variations in the tropical Indian Ocean region result from changes in the Indian Summer Monsoon (ISM), as well as convective and cyclonic rainfall. The relative roles of such forcing can be elucidated by constructing robust paleoclimate records, which help to better predict future variability in precipitation due to rising greenhouse gases. This study was carried out using a suite of paleoclimate proxies on a combination of marine and terrestrial sediment cores from Sri Lanka.

Maritime pollution in the Indian Ocean after the MV X-Press Pearl accident.

The MV X-Press Pearl marine debacle severely affected the marine environment in the Indian Ocean. The objective of this study is to monitor environmental pollution along the west coast of Sri Lanka. Beach sand samples were collected from 40 locations.
