A study has been carried out by comparing the extreme wind speeds estimated based on NCEP/NCAR reanalysis data for 100 years return period using Fischer Tippet-1 (commonly known as Gumbel) and Weibull distributions for three locations (off Goa, Visakhapatnam and Machilipatnam) in the north Indian Ocean. The wind dataset for Goa is compared with that from ERA-40 data. For higher wind speeds (12–20 m s−1), NCEP wind speed has higher percentage of occurrence than that of ERA-40.
Newly detected rising sea levels in parts of the Indian Ocean have led Indian scientists to conclude that the Indian Ocean is rising faster than other oceans.

Grim tidings from the Mumbai oil spillA Toxic Brew
The collision between two ships off Mumbai has resulted in an environmental catastrophe
There is a humongous oil slick
Mangroves along the coast have suffered. So too has marine and bird life.
It may take months to clear the slick, locate oil containers.
Sedimentological and stable isotopic characteristics of sediments have been studied in a core from the south-eastern Arabian Sea containing records of the past 70 ka.
Mumbai: Mangroves near the Elephanta Island in the Mumbai harbour and those near Vashi in Navi Mumbai were found to be affected on Wednesday, after merchant vessel MSC Chitra collided with MV Khalijia-III, leading to a massive oil spill in the Arabian Sea off Mumbai. There is, however, no estimate of the scale of the damage.
India has a vast extent of coast line of about 8000 km spanning 13 maritime mainland states and Union Territories, which are home to a diversity of coastal and marine ecosystems, comprising nationally and globally significant biodiversity (Venkataraman and Wafar, 2005). It also supports almost 30% of its human population being dependent on the rich exploitable
The seasonal variability of phytoplankton biomass in the Arabian Sea, though a well researched topic, its inter-annual variability is less explored and understood. Analysis of the satellite-derived chlorophyll pigment concentration in the Arabian Sea during 1997
After bringing a rail line close to the Indian border with Tibet, China is gearing to push a rail link across the Karakoram into Pakistan through the Gilgit-Baltistan region that is part of the original state of Jammu and Kashmir.
Satellite observations over the Arabian Sea revealed anomalous cooling in February 2008 associated with the anomalous north westerly winds from the continent. Land
