This may be related to global changes in oceanic circulation.

Oceanic circulation contributes significantly to the climate, especially near coastal areas.

Large-scale oceanic circulation has a direct impact on opal deposition.

Restricted oceanic circulation in the west led to extensive evaporite formation.

The breakdown in the oceanic circulation patterns brought up nutrients from the abyssal waters.

This equator-versus-pole energy imbalance is the fundamental driver of atmospheric and oceanic circulation.

Significant papers on colour sensation appeared in 1871-2, being followed by work on oceanic circulation, glacier motion, and changes of state.

This obstruction in oceanic circulation led to 'death in the depths' from oxygen deprivation.

Is the atmospheric/oceanic circulation changing?

Major freshwater release into the Arctic Ocean is considered to disrupt oceanic circulation and cause temporary cooling.

This seems to have been an indicator of shifted oceanic circulation patterns and possibly changed wind direction and speed (Meronen et al. 2012).

This process resulted in profound changes in the oceanic circulation patterns, which shifted global climates towards colder conditions.

Pan-oceanic response to increasing anthropogenic aerosols: impacts on the Southern Hemisphere oceanic circulation.

Through sampling, they look at millions of years of history of sea-floor spreading, plate tectonics, and oceanic circulation and climates.

This may indicate an influx of nutrient-rich-hence corrosive-Antarctic Bottom Water, due to a reconfiguration of oceanic circulation patterns.

The Atlantic Heat Piracy model suggests that changes in oceanic circulation cause one hemisphere's oceans to become warmer at the other's expense (Seidov and Maslin 2001).

Pangaea's formation would also have altered both oceanic circulation and atmospheric weather patterns, creating seasonal monsoons near the coasts and an arid climate in the vast continental interior.

The Isthmus of Panama developed at a convergent plate margin about 3 million years ago, and further separated oceanic circulation and created the Pacific and Atlantic oceans.

These processes all contribute to the transfer of nutrients, oxygen, and trace chemicals, ocean stratification and density fields, and patterns of warmth that drive atmospheric and oceanic circulation.

Finally, changes in atmospheric and oceanic circulation patterns caused by a global temperature change may cause more heat to be transferred to the Arctic, enhancing Arctic warming (ACIA 2004).

According to Schwimmer, the growth ring patterns observed could have been affected by a variety of factors, including "migrations of their prey, wet-dry seasonal climate variations, or oceanic circulation and nutrient cycles".

This could happen if sea water expanded and its level rose as a result of global warming, for example, or if any change in oceanic circulation patterns resulting from climatic change produced warmer ocean waters around Antarctica.

The cryosphere is an integral part of the global climate system with important linkages and feedbacks generated through its influence on surface energy and moisture fluxes, clouds, precipitation, hydrology, atmospheric and oceanic circulation.

The atmospheric and oceanic circulation redistributes some of this energy as sensible heat and latent heat partly via the mean flow and partly via eddies, known as cyclones in the atmosphere.

In this simple, modeling setting, the principal factors that were accounted for influencing the oceanic circulation were surface wind stress, bottom friction, a variable surface height leading to horizontal pressure gradients, and finally, the Coriolis effect.
