Although that in itself was initially a mystery, scientists now know these animals release tiny larvae that get carried by ocean currents to different vents, where they settle and form a new colony.

Most marine fishes have a pelagic larval stage that drifts in the surface or near - surface currents of the ocean — an environment very different from the one they inhabit as adults.

But in a new study in Nature, researchers show that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times, suggesting that at least one arm of the system of global ocean currents that move heat around the planet has behaved similarly under vastly different climOcean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times, suggesting that at least one arm of the system of global ocean currents that move heat around the planet has behaved similarly under vastly different climocean currents that move heat around the planet has behaved similarly under vastly different climates.

This current therefore is a major region for mixing water between different ocean basins.

Key features of the lesson are: The lesson about how altitude, latitude, ocean currents, air masses and air pressure cells affect the climates of different places.

As the old man stares out over the English Channel that divides Saleem from his family, we read that «From here is was easy to see the currents, linear streams of water a shade different from the rest of the ocean, like secret passages within the depths.»

Home to five different species of salmon, the river is most prolific in summer when thousands of salmon complete a four year quest, returning from the ocean to swim upstream against the current, returning to their spawning grounds.

I'm a fish geneticist so I won't bother commenting on «paleo - ocean current - ology», but it seems to me that glaciation would result in a reduction of fresh water inputs to the North Atlantic (during the ice age) and would therefore be quite different from the mechanism in question (which is related to early phases of global warming).

Plate tectonics have changed the ocean currents since the Pliocene and so maybe we'll see a different result.

You seem to be suggesting that this slightly different warming pattern would lead to wind and ocean current changes, leading to different climate patterns.

Many different models have now demonstrated that our understanding of current forcings, long - term observations of the land surface and ocean temperature changes and the canonical estimates of climate forcing are all consistent within the uncertainties.

So, if some of these ideas on termination of glaciations are correct (ice - sheet temperature, ocean circulation and CO2), and all of these are omitted from the current model, it leaves open the possibility that a more comprehensive model would get a different result.

While earlier studies of northern ocean currents had relied on computer simulations, this later study is different: it is based on direct observation of what is actually happening in the Atlantic and Arctic oceans.

They have to be quick to react, because different masses of water are often very different in salinity, pH, DIC, and alkalinity... if the ocean creatures couldn't adapt very quickly to the shock of some storm - or current - driven new water mass coming through the area where they live, they'd have gone extinct millennia ago.

Ocean currents sometimes mix and sometimes stratify the signals from different parts of the oceans, but since they, too, can change with season, with wind direction and velocity, and with changes in THC / MOC, they also create variations in SST.

So the implication is that while, over the oceans in a broader sense my thesis may still be correct as a generalization, whatever happens in the NINO zones is driven by something completely different e.g. massive upwelling, currents etc..

The oceans are really big, yet the presence of currents and layers at different temperatures means temperatures can be quite different in waters just a few hundred meters apart.

Previous large natural oscillations are important to examine: however, 1) our data isn't as good with regards to external forcings or to historical temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic data, and paleoclimate temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth from the oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global temperature associated with major ocean current shifts which for the most part haven't been seen.

I wouldn't be surprised that over longer terms than we have decent data, it doesn't slosh through the arctic ocean both directions at different times, as well as circular ocean currents in both northern and southern oceans while waters flow through the arctic in the north, and around Antarctica in the Southern ocean.

Positions of continents shifted, ocean currents took a different course, and estimated CO2 levels were between twice and ten times of present values during most of this time.

Yah — CO2 was higher millions of years ago, but twas a very different planet back then, solar radiation about 6 % lower, different day length, continents and hence ocean currents in a completely different configuration.

Since the ocean currents vary with depth, the sediment in the cores can flow to the core location from different directions.

Similarly, the buoy anchors lines could be equipped with instrumentation to collect data on ocean currents, temperature or chlorophyll concentrations at different depths.

Consider the facts: the climate system is indicated to have left the natural cycle path; multiple lines of evidence and studies from different fields all point to the human fingerprint on current climate change; the convergence of these evidence lines include ice mass loss, pattern changes, ocean acidification, plant and species migration, isotopic signature of CO2, changes in atmospheric composition, and many others.

The computer simulation revealed a backward spinning planet with a dramatically different distribution and abundance of desert lands, an otherworldly surge of cyanobacteria, and rerouted ocean currents, among other differences from our real, familiar planet.

In the Arctic that can result in a weaker gulf stream in the North Atlantic, while in the southern ocean, would the same mechanism increase the flow of water into the Humboldt current (what doesn't plunge down has to go somewhere)- behaviour of both currents are different due to land mass distribution.

Solving the mystery of these remarkably different patterns of sediment dissolution in different oceans is a vital key to understanding the rapid warming of this period and what it means for our current climate.

However the tidal currents coming into contact with the relief of the ocean bottom (even if this is very deep) creates waves which are propagated at the interface between two layers of different densities.
