Mathematical modelling and time series analysis techniques are important tools for extracting information from complex geotime series. These techniques also facilitate a fair degree of prediction, which is one of the prime goals of science. The data analysis strategy for such a purpose mainly involves spectral analysis and pattern classification.

A $500 million North Atlantic shrimp fishery may be vulnerable to climate change that could disrupt the crustaceans' life cycle and mislead them into hatching when food is scarce, scientists said.

India's monsoon rains, vital for the farm-dependent economy and the success of major crops, may exceed the norm this year if the El Nino system that brings drier weather fails to appear, as expected, forecasters say.

Overfishing will wipe out the breeding population of Atlantic bluefin tuna, one of the ocean's largest and fastest predators, in three years unless catches are dramatically reduced, conservation group WWF said on Tuesday.

A model analysis of the uptake of carbon dioxide in the North Atlantic carries with it a cautionary reminder about interpreting what may be short-term trends as signals of long-term climate change.

Washington: A new study has determined that global warming may have hit a speed bump and could go slow down for decades.


The asynchronous relationship between millennial-scale temperature changes over Greenland and Antarctica during the last glacial period has led to the notion of a bipolar seesaw which acts to redistribute heat depending on the state of meridional overturning circulation within the Atlantic Ocean.

The ocean has the ability to control weather systems globally

The Atlantic meridional overturning circulation (AMOC) transports warm salty surface waters to high latitudes, where they cool, sink and return southwards at depth. Through its attendant meridional heat transport, the AMOC helps maintain a warm northwestern European climate, and acts as a control on the global climate.

London: More than a quarter of sharks and rays in the northeast Atlantic face extinction through the effects of over fishing, with 7 per cent classed as critically endangered, conservationists have warned.
