The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
CHENNAI: The Water Resources Department has approached the Department of Ocean Engineering, IIT-Madras, to scrutinise its report of the project to control sea erosion along the coastline, including along Ennore High Road. Officials of the WRD said as the project is to be implemented with a new technology, the expertise …
A state of the art model of the coupled ocean-atmosphere system, the climate forecast system (CFS), from the National Centres for Environmental Prediction (NCEP), USA, has been ported onto the PARAM Padma parallel computing system at the Centre for Development of Advanced Computing (CDAC), Bangalore and retrospective predictions for the …
The disintegration of ice shelves, reduced sea-ice and glacier extent, and shifting ecological zones observed around Antarctica highlight the impact of recent atmospheric and oceanic warming on the cryosphere. Observations and models suggest that oceanic and atmospheric temperature variations at Antarctica's margins affect global cryosphere stability, ocean circulation, sea levels …
IN WHAT could have ramifications on the ocean food web, scientists have found that rising acidity of seawaters slows down marine nitrogen cycle. Ocean acidification is the result of CO2 dissolving in seawater and lowering its pH. Scientists know that a drop in ocean pH affects carbon cycle, reducing carbonate …
In the late 1980s, US scientists discovered an organism in the Atlantic Ocean. Later research revealed the organism, christened prochlorococcus, as amongst the most plentiful on the earth. It’s also a veritable trove of oxygen. In recent times, scientists have made attempts to stimulate the growth of prochlorococcus but their …
Significant warming has been observed in every ocean, yet our ability to predict the consequences of oceanic warming on marine biodiversity remains poor. Experiments have been severely limited because, until now, it has not been possible to manipulate seawater temperature in a consistent manner across a range of marine habitats. …
KOLKATA, 12 JAN: The School of Oceanographic Studies, Jadavpur University, in a study found that water level in the Bay of Bengal off the Sunderbans coast has risen four times over the past nine years. The sudden rise is posing a real threat to the Sagar Island among other islands …
The Gulf coastal ecosystems in Florida are foci of the highest species richness of imperiled shoreline dependent birds in the USA. However environmental processes that affect their macroecological patterns, like occupancy and abundance, are not well unraveled. In Florida the Snowy Plover (Charadrius alexandrinus nivosus) is resident along northern and …
New Delhi: The environment ministry on Friday notified the long-pending Coastal Zone Regulations, changing the regime that manages development and construction along the 7,500 km coastline of the country. Environment minister Jairam Ramesh announced the notification and said state-level authorities would be given four months to identify all contraventions of …
Ocean acidification produced by dissolution of anthropogenic carbon dioxide (CO2) emissions in seawater has profound consequences for marine ecology and biogeochemistry. The oceans have absorbed one-third of CO2 emissions over the past two centuries, altering ocean chemistry, reducing seawater pH, and affecting marine animals and phytoplankton in multiple ways. Microbially …
Washington: Lurking in the depths of a California lake, researchers found a bacteria that can thrive on arsenic, an explosive discovery that could expand the search for other life on Earth and beyond. The Nasa-funded findings redefines what science considers the necessary elements for life, currently viewed as: carbon, hydrogen, …
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. This helped to understand …
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 …
In 2000, the British research ship Discovery was caught in a fearsome storm. As the battered vessel struggled into the dock, scientists discovered that the ship’s research devices were working. The data confirmed waves more than 60 feet high. Scientists had earlier scoffed at seafarers’ stories about rogue waves: their …
Now it is possible to experience life beneath the ocean on your computers. A team of researchers from the James Cook University (JCU) has developed ocean mapping technology which makes it possible to view the underwater landscape. The team devoted three years to produce a three dimensional, high resolution map …
Conspicuous global stable carbon isotope excursions that are recorded in marine sedimentary rocks of Phanerozoic age and were associated with major extinctions have generally paralleled global stable oxygen isotope excursions. All of these phenomena are therefore likely to share a common origin through global climate change. Exceptional patterns for carbon …
