A lethal and highly contagious marine virus has been detected for the first time in wild salmon in the Pacific Northwest, researchers in British Columbia said on Monday, stirring concern that it co
The Marshall Islands in the Pacific Ocean is to ban shark fishing and trade in shark products throughout its waters, creating a sanctuary roughly eight times the size of the UK.
The anthropogenic input of fossil fuel carbon into the atmosphere results in increased carbon dioxide (CO2) into the oceans, a process that lowers seawater pH, decreases alkalinity and can inhibit the production of shell material. Corrosive water has recently been documented in the northeast Pacific, along with a rapid decline in seawater pH over the past decade. A lack of instrumentation prior to the 1990s means that we have no indication whether these carbon cycle changes have precedence or are a response to recent anthropogenic CO2 inputs.
Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variations in population sizes and trends, as well as reproduction and morphology.
Vast deposits of rare earth minerals have been discovered on the seabed of the Pacific Ocean amounting to 1,000 times those on land, media reported on Monday citing a study by Japanese researchers.
The deposits are estimated to amount to 100 billion metric tons, the Nikkei business daily said.
They are believed to lie at a depth of 3,500 to 6,000 meters and cover an area of over 11 million s
World demand for rare-earth elements and the metal yttrium—which are crucial for novel electronic equipment and green-energy technologies—is increasing rapidly. Several types of seafloor sediment harbour high concentrations of these elements.
This study investigates changes in the mixed layer depth (MLD) in the North Pacific Ocean in response to global warming and their impact on primary production by comparing outputs from 11 models of the coupled model intercomparison projects phase 3. The MLD in the 21st century decreases in most regions of the North Pacific, whereas the spatial pattern of the MLD is nearly unchanged. The overall shoaling results in part from intensified upper-ocean stratification caused by both surface warming and freshening.
Methylmercury cycling in the Pacific Ocean has garnered significant attention in recent years, especially with regard to rising mercury emissions from Asia. Uncertainty exists concerning whether increases in anthropogenic emissions over time may have caused increased mercury bioaccumulation in the biota.
Washington: Moses might not have parted the Red Sea, but a strong east wind that blew through the night could have pushed the waters back in the way described in biblical writings and the Quran, US researchers reported.
Computer simulations, part of a larger study on how winds affect water, show wind could push water back at a point where a river bent to merge with a coastal lagoon, the tea
Using over 1.6 million profiles of salinity, potential temperature, and neutral density from historical archives and the international Argo Program, this study develops the three-dimensional field of multidecadal linear change for ocean-state properties. The period of analysis extends from 1950 to 2008, taking care to minimize the aliasing associated with the seasonal and major global El Niño–Southern Oscillation modes. Large, robust, and spatially coherent multidecadal linear trends in salinity to 2000-dbar depth are found.
