The mystery surrounding the surfacing of tar balls on Goan beaches has apparently been solved with the National Institute of Oceanography revealing that they originate from washing away of oil spil

Variations in nearshore wave power at four shallowwater locations along the east and west coast of India are examined based on the measured wave data for one-year period. The study shows that along the west coast of India, 83–85% of the annual wave power is during the summer monsoon period (June–September), whereas at Visakhapatnam (on the east coast), 55% of the annual wave power is during the summer monsoon period. Along Puducherry coast in the east, wave power is relatively less with maximum value of 31.8 kW m–1.

PANJIM: Goa State Pollution Control Board has issued notices to transporters of hazardous waste oils, which are generated from barges, cruise ships, off-shore casino vessels and other ships docking in Goa for failing to submit the annual details regarding collection and disposal of waste oil.

The notices have been served to 13 transporters under Hazardous Waste (Management, Handling and Transboundary Movement) Rules 2008 asking ‘why the authorization (consent to operate) granted under said rules should not be revoked/withdrawn in view of non compliance of conditions.’

Temperature To Rise After Sky Clears Today

Despite a rise in temperature, Delhiites did not feel the heat on Thursday, first due to a haze in the morning and later a cloudy sky. The cloud cover this time is not a result of a western disturbance but has been caused by a convergence of winds coming from the west and east and is expected to dissipate by Friday.

Kolhapur: A fresh study of the earthquake-prone areas in the Koyna-Warna reservoir area is under way. A team of scientists from the CSIR-National Geophysical Research Institute, Hyderabad, has arrived here and is expected to study the areas where seismic activity has been prevalent at low or medium intensity.

The scientists will use the Airborne LiDAR (Light Detection and Ranging) and photographic data acquisition and processing system for geomorphological and structural studies. The one-month study will focus on the tectonic activities around the Warna and Koyna dams.

Flash floods on the edge of high terrain, such as the Himalayas or Rocky Mountains, are especially dangerous and hard to predict. The Leh flood of 2010 at the edge of the Himalayan Plateau in India is an example of the tragic consequences of such storms. The flood occurred over a high mountain river valley when, on three successive days, diurnally generated convective cells over the Tibetan Plateau gathered into mesoscale convective systems and moved off the edge of the Plateau over Leh.

At least five private companies under scanner

The Central Bureau of Investigation has registered a preliminary enquiry to probe alleged irregularities in issuance of licences to at least five private companies for exploration of mineral wealth in the Bay of Bengal and the Arabian Sea during 2010-11. The prime allegation is that licences for 28 of the 62 offshore mines were granted to companies owned by the son and brother of an Indian Revenue Officer in conspiracy with unknown officials of the Indian Bureau of Mines and the Union Ministry of Mines.

NEW DELHI, 24 SEPT: Just a week after filing cases in the coal block allocation scam, the CBI has begun probing alleged irregularities in the country's first-ever attempt to explore untapped minera

New Delhi After filing a series of cases in the coal block allocation scam, the CBI has now been tasked with unearthing alleged irregularities in the allocation of offshore mining licenses to private firms.

The CBI has registered a preliminary enquiry into allocation of 62 off-shore mineral blocks in the sea bed of of Bay of Bengal and Arabian Sea, the first-ever attempt to explore untapped mineral wealth worth thousands of crore.

Arabian Sea tropical cyclones have become stronger over the past 30 years owing to a reduction in vertical wind shear (VWS) brought about by radiative forcing from pollution aerosols1. Wang et al.2 argue that the decline in VWS results from a systematic shift in storm genesis date, which may be part of a natural cycle or another consequence of regional pollution. However, their conclusions2, although interesting, are not supported by our analysis and are probably sensitive to biases in the observational record.
