Forty years after the ocean floor was first mapped by hand, a team of Australian researchers has created the first digital map of the entire sea floor. Made by the University of Sydney's School of Geosciences and National ICT Australia (NICTA), the map can be used to plot the planet's underwater carbon sinks and understand how oceans respond to climate change.

After several tsunami events with disastrous consequences around the world, coastal countries have realized the need to be prepared to minimize human mortality and damage to coastal infrastructures, livelihoods and resources. The international scientific community is striving to develop and validate methodologies for tsunami hazard and vulnerability and risk assessments. The vulnerability of coastal communities is usually assessed through the definition of sets of indicators based on previous literature and/or post-tsunami reports, as well as on the available data for the study site.

The Regional State of Coast Report for the western Indian Ocean (WIO) is the first comprehensive regional synthesis to provide insights into the enormous economic potential around the WIO, the consequential demand for marine ecosystem goods and services to match the increasing human population, the pace and scale of environmental changes taking

This new study led by an Indian scientist Dr Roxy Mathew Koll, from the Indian Institute of Tropical Meteorology (IITM) Pune, points out a significant decreasing trend in the summer monsoon rainfall over the central Indian subcontinent during the past century. It suggests an important role of the rapid warming in the Indian Ocean in weakening of monsoon circulation and rainfall.
