The NIOT was established in 1993 for catering to the requirement of developing technology for exploring oceans and harnessing underwater resources.

Studying stalagmites and their deposits can reveal the frequency and magnitude of dry and wet seasons in the past. Such studies can help predict climate uncertainties.

Nitrogen-15 is an isotope that is useful in determining how much of the anthropogenic carbon dumped in the atmosphere is taken up by the oceans. Our efforts in the Indian Ocean to determine this rate is outlined here.

With drastic alterations in climate anomalies, there is a need for adequate mitigation and preparedness computations that can help reduce the impact of environmental disasters. Scientific predictions and planned methodologies can help, although it is yet not possible to completely safeguard against the unpredictable and uncontrollable forces of nature.

Nitrogen an essential macronutrient of the oceanic ecosystem, can limit the biological production if not available in a suitable form or concentration. This article looks at the role of nitrogen in the waters of the Arabian Sea.

There appears to be a consensus now among climate scientists that man has significantly altered his environment by indiscriminate burning of fossil fuels; and this anthropogenic effect on climate has exceeded solar heating of the earth in the past two decades. Advanced models of climate have clearly shown that the unprecedented high temperatures recorded in the late nineties could not be explained if man made changes in the atmospheric chemistry are not taken into account. Therefore, it is time that we think about possible ways of coping with a warmer world in the near future.
