This study discusses the upwelling observed in Prydz Bay, coastal waters of East Antarctica. In February 2006, as a part of expedition to Larsemann Hills (East Antarctica) three hourly conductivity, temperature, depth (CTD) observations were carried out for three consecutive days in Prydz Bay coastal waters.
Iron fertilization of the Southern Ocean is believed to counter the increasing CO2 concentration in the atmosphere and the consequent global warming.
Though a number of large scale iron enrichment experiments have been done in the recent past in different parts of the world ocean, little effort has been made to understand the effect of iron enrichment on nitrogen uptake rates and f-ratios.
It has long been felt that our natural environment should be mapped and monitored with active participation of agencies responsible for managing natural resources, industry groups and community organizations. This organized information forms a basis for storing soil and land databases for the implementation and monitoring of various efforts on land resource management.
The effect of sub-lethal concentrations (LC20 =0.0002 and 0.001 ppm, and LC40 = 0.002 and 0.02 ppm for II and IV instar larvae respectively) of a dispersible concentrate formulation of the insect growth regulator, lufenuron on larval growth and development of Aedes aegypti was studied.
Sequestration of atmospheric carbon to the soil is a challenging task for the scientific community to mitigate the rising concentration of atmospheric carbon dioxide (CO2). Biochar, due to its aromatic structure
and long mean residence time in the soil (more than 100 years) has the potential for long-term carbon sequestration in the soil.
There is one being-Indian-thing, which spans the urban or rural, rich and poor divide: our annual watch and wait for the monsoons. It begins every year, without a fail as heat climbs, and monsoons advance. The farmers wait desperately because they need the rain, at the right time, to sow their crops. Without this water, they cannot plant.
Chilli-based repellents have shown promise as deterrents against crop-raiding elephants in Africa. The authors experimented with ropes coated with chilli-based repellent as a cheap alternative to existing elephant crop raid deterrent methods in India.
The recent news items on the loss of stored grains in the godowns of the Food Corporation of India (FCI) created a huge uproar not only due to the wastage of grains but also because it was the time when the Government was planning the National Food Security Act amidst increasing inflation in the prices of edible commodities.
This is a brief response to Sunita Narain's thought-provoking piece on the role of monsoon in our lives. As scientists actively involved in understanding the Indian monsoon and its prediction, we have attempted to elucidate what we know about this intriguing phenomenon, which is a tantalizing mixture of order and chaos, the problems of predicting it and our expectation of the progress that could be achieved in the near future.
