Recent observational surveys have shown significant oceanic bottom-water warming. However, the mechanisms causing such warming remain poorly understood, and their time scales are uncertain. Here, we report computer simulations that reveal a fast teleconnection between changes in the surface air-sea heat flux off the Ad
Seasonal (spring and summer) depletion of dissolved inorganic carbon occurs in the surface mixed layers of most of the unproductive or oligotrophic regions of the world's oceans. The missing dissolved inorganic carbon is thought to be converted to particulate carbon by photosynthesis, yet there are seemingly insufficient dissolved nutrients present to support the required amount of plant growth.
Fisheries bycatch is a primary driver of population declines in several species of marine megafauna (e.g., elasmobranchs, mammals, seabirds, turtles). Characterizing the global bycatch seascape using data on bycatch rates across fisheries is essential for highlighting conservation priorities.
Warming decreases low-level cloud cover, contributes to its own increase WHEN the oceans warm, water evaporates and cloud cover increases. This is the well known science behind cloud formation. A new study begs to differ. Of the three major kinds
Feedbacks involving low-level clouds remain a primary cause of uncertainty in global climate model projections. This issue was addressed by examining changes in low-level clouds over the Northeast Pacific in observations and climate models.
Mercury emissions are poisoning seafood amongst the chemicals that poison fish, methyl mercury is one. An environmental pollutant, it makes its way into the ocean where it enters the food chain and is consumed by fish which are eaten by humans. In the US, 40 per cent of all human exposure to mercury is from tuna harvested in the Pacific Ocean, the northern part of which was the study
Beneath the waves of this sapphire-blue corner of the East China Sea, a team of divers was busily at work.
Hovering along the steep, bony face of a dying coral reef, some divers bored holes into the hard surface with compressed-air drills that released plumes of glittering bubbles. Others followed, gently inserting small ceramic discs into the fresh openings.
Marine litter is a global concern affecting all the oceans of the world. It poses environmental, economic, health and aesthetic problems that are rooted in poor solid waste management practices, lack of infrastructure, indiscriminate human activities and behaviours and an inadequate understanding on the part of the public of the potential consequences of their actions.
