After detailed analysis, the conclusion is that Japan should be responsible for the obligation of immediate notification and since Japan unilaterally discharge the wastes without prior specific permits of other contracting countries, it should also be responsible for the violation of prevention of dumping. Since so far, no material injury has emerged and there would [...]

There are concerns that sea-level rise resulting from climate change could lead to saltwater intrusion into coastal aquifers. However, a study shows that groundwater extraction is the main driver of saltwater intrusion in the United States, highlighting the importance of sustainable water management. doi: http://dx.doi.org/10.1038/nclimate1413

Global warming contrarians remind the public that the world has not warmed all that much, if at all, during the past decade or so. But that’s the atmosphere. Oceanographers with their thermometers in Earth’s biggest reservoir of heat—the world’s ocean—report in a paper to be published in Geophysical Research Letters that greenhouse warming has in [...]

Last month, preparatory work began on the Xiaonanhai Dam, with more projects to follow. Within a few years, the Jinsha will slow to a sluggish pace and its temperature will drop as a series of large hydropower dams release cold bottom water from their reservoirs into the river. For species already threatened by the Three [...]

In the present investigation, the most commonly used pharmaceutical drug Ibuprofen (IB) was exposed to an Indian major carp Cirrhinus mrigala under static bioassay method to estimate its toxicological effects for a period of 35 days. The median lethal concentration (LC 50) of IB to the fish C. mrigala for 24 h was found to [...]

Acoustic surveys of New Zealand deep-water seamounts often show fish aggregations up to 150 m high on the summit. Although bottom trawls on the seamount slopes catch predominantly orange roughy (Hoplostethus atlanticus), species composition in the midwater plumes is extremely uncertain. In June 2010, moored underwater video cameras were deployed on the summit of the [...]

A major finding is detection of Fukushima-derived 134Cs and 137Cs throughout waters 30–600 km offshore, with the highest activities associated with near-shore eddies and the Kuroshio Current acting as a southern boundary for transport. Fukushima-derived Cs isotopes were also detected in zooplankton and mesopelagic fish, and unique to this study we also find 110mAg in [...]
