The Malaspina Expedition, led by the Spanish National Research Council, has demonstrated that there are five large accumulations of plastic debris in the open ocean that match with the five major twists of oceanic surface water circulation.
Their analysis, which could discern human - derived nitrogen from natural nitrogen fixation, revealed that the oceanic nitrate concentration increased significantly over the last 30 years in surface waters of the North Pacific due largely to the enhanced deposition of nitrogen from the atmosphere.
Note that Ekman pumping does not penetrate deep into the oceanic interior, but since the trades advect the surface waters westward, the upper layer of warm sea water is deeper in the west than in the east.
After participation in a ship expedition with RV SONNE to the North Pacific in summer 2018, the tasks include to reconstruct the spatial and temporal changes in near - surface and subsurface water temperatures in the North Pacific, salinity, thermocline depth, and water mass stratification of the upper oceanic surface using geochemical proxy parameters, e.g. in planktic microfossils.
Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; diminishing snow cover; shrinking sea ice; rising sea levels; ocean acidification; and increasing atmospheric water vapor.
Climate - driven variation affects oceanic communities from surface waters to the much - overlooked deep sea....»
Occurring offshore in blue oceanic waters, the blue marlin prefers to stay in the warm waters near the surface, above the thermocline.
Note that Ekman pumping does not penetrate deep into the oceanic interior, but since the trades advect the surface waters westward, the upper layer of warm sea water is deeper in the west than in the east.
Ocean serves as the memory whereby slow oceanic Rossby waves and Kelvin waves propagate through the basin and affect the depth of the oceanic surface layer of warm water.
In addition to expending some of the oceanic heat, the wave action of the cyclone tends to mix the cooler ocean waters below toward the surface, reducing sea surface temperatures after the cyclone passes.
When Lacis becomes an expert on clouds, water vapor, oceanic heat storage, aerosols, programming GCMs, measuring and adjusting surface temps, and paleo - climate; then maybe I'll care what he says about what might happen over the next 10 to 20 years (but not the next hundred, because no one knows that).
Water columns are much more strongly stratified in the tropics than in higher latitudes, so it takes a lot less energy to move parcels from deep oceanic layers to the surface in high latitudes — and, not surprisingly, this is where most communication occurs between deep and surface waters.
In the mid-18th century, some researchers began recording measurements of the water temperature at the ocean's surface while on scientific oceanic voyages.
Causality is always tricky to assign in cases such as this one, since it's entirely possible that the ridging itself has led to warm surface water though decreased oceanic mixing by wind and unusually high air temperatures.
The most common means of slowing AMOC involves the reduction of oceanic surface water density via an increase in freshwater discharge to the North Atlantic.
The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.
What the real big news is, is the overall cooling of the oceanic surface waters now down to +.155 c from summer readings around +.34 c.
Figure 2 - B suggests that since 1979 there has been a jump of at most 0.3 °C during the great El Niño of 1997 - 98; (see figure 15 - A showing that El Niño paces the global temperatures as the water of the warm pool is redistributed to the oceanic surface layer at higher latitudes).
Water now returning to the surface having entered deep ocean during the MWP may be inducing release of oceanic CO2 in response to altered pH, and this release could be expected to provide the steady increase in atmospheric CO2 concentration (of at least 1.5 ppm / year) that is observed to be independent of temperature variations.
At the same time, they point towards below normal ice extent in the Barents / Kara Sea, also compared to the record minimum in 2007, which they see coupled to oceanic processes and promoting further warming of surface waters in the region.
Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; diminishing snow cover; shrinking sea ice; rising sea levels; ocean acidification; and increasing atmospheric water vapor.
The real reasons for climate changes are uneven solar radiation, terrestrial precession (that is, axis gyration), instability of oceanic currents, regular salinity fluctuations of the Arctic Ocean surface waters, etc..
These OMITTED / POORLY Represented processes include the following: oceanic eddies, tides, fronts, buoyancy - driven coastal and boundary currents, cold halocline, dense water plumes and convection, double diffusion, surface / bottom mixed layer, sea ice — thickness distribution, concentration, deformation, drift and export, fast ice, snow cover, melt ponds and surface albedo, atmospheric loading, clouds and fronts, ice sheets / caps and mountain glaciers, permafrost, river runoff, and air — sea ice — land interactions and coupling.
