From 1998 to 2008, Jon's OCEANS 8 project, a series of expeditions to explore the world's ocean from the seat of a sea kayak, allowed Jon and his teams—comprising some of the world's best photographers, filmmakers, scientists and navigators—to reach corners of the world rarely seen.
The First World Ocean Assessment of 2015 showed that the ocean is important for the climate and support of life on the whole planet, and that critical ocean systems are under threat, making the exploration and mapping of the ocean a key environmental goal to facilitate understanding of the dynamics of ocean systems and the changes that are ...
Ocean warming causes water stratification, deoxygenation, and the formation of dead zones. Dead zones and OMZs are hotspots for anammox and denitrification, causing nitrogen loss (N 2 and N 2 O). Elevated atmospheric carbon dioxide acidifies seawater, decreasing pH-dependent N-cycling processes such as nitrification, and enhancing N 2 fixation ...
The risk is unacceptable unless the diver is physically constrained from approaching the thrusters' danger zones. This is achieved by deploying the divers by diving stage or bell, limiting the length of excursion umbilical that can be let out, and using underwater tending points where necessary. Scuba is not used from dynamically positioned ...
The Atlantic Ocean is teeming with life, but for the first time researchers have discovered dead zones in these waters - areas low in both oxygen and salinity - off the coast of Africa. Fish can't ...
Increasing interest of member states of the International Seabed Authority have led to 18 exploration contracts to be carried out in the Clarion–Clipperton fracture zone of the Pacific Ocean. [40] The result of the exploration and associated research is the discovery of new marine species as well as microscopic microbes which may have ...
Stinging jellyfish, rays with their whip-like tails and sharks on the hunt are some ocean hazards that might typically worry beachgoers. Six people drowned in rip currents over a recent two-day ...
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
