Sea Temperature Changes Linked to Mystery North Pacific Ecosystem Shifts

Longer, less frequent climate fluctuations may be contributing to abrupt and unexplained ecosystem shifts in the North Pacific, according to a study by the University of Exeter.

Longer, less frequent climate fluctuations may be contributing to abrupt and unexplained ecosystem shifts in the North Pacific, according to a study by the University of Exeter.

Researchers have long been puzzled by two rapid and widespread changes in the abundance and distribution of North Pacific plankton and fish species that impacted the region’s economically important salmon fisheries. In 1977, and again in 1989, the number of salmon in some areas plummeted, while it increased in other areas. These events have been dubbed regime shifts by researchers.

Perhaps what was missing in their formula for calculation is the cyclical heating of the oceans by ‘mantle plumes’ as a natural reaction when the Earth goes through periods of an over-heated outer and inner core and the result of cyclical surges of charged particles coming from various sources such as the Sun, our galaxy Milky Way, neighboring galaxies, occasional gamma ray burst, pulsars, neutron stars, redshifts and others.

The Earth’s natural course of action to displace this overheating is by “sweating”. The way the Earth sweats is through its pores – what we call mantle plumes which form as tunnels or channels from the outer core boundary, making their way upward through the upper mantle and often punch their way through the lithosphere and find their way to the surface in the way of undersea or surface volcanoes. But it can take another form in the way much like a tsunami surge or flood which would travel horizontal just under the surface crust and sea bottoms.

Now, in a paper published in the Proceedings of the National Academy of Sciences (PNAS), researchers Dr Chris Boulton and Professor Tim Lenoton show that the variability of the North Pacific itself has been changing and that marine ecosystems are sensitive to this. They analyzed sea surface temperature fluctuations in the North Pacific since 1900 and identified a trend toward longer-lived fluctuations. The authors also found the same pattern in the Pacific Decadal Oscillation index, a widely cited indicator of Pacific climate variability that has previously been linked to the 1977 and 1989 regime changes.

These findings reveal a fundamental change in Pacific climate variability over the last century, to a pattern of oscillations in which the region’s ecosystems are more likely to exhibit larger and more abrupt climate-triggered regime shifts. This suggests that changing climate variability contributed to the North Pacific regime shifts in 1977 and 1989.

Dr Chris Boulton, at the University of Exeter, said: “The causes of these dramatic ecosystem shifts in 1977 and 1989 have been a scientific mystery. This is the first time that anyone has looked for changes in sea surface temperature fluctuations in the North Pacific, and we have now gone some way towards explaining what causes these regime shifts, which have extreme consequences for aquatic life.”

Professor Tim Lenton, of the University of Exeter, added: “This study shows that the ongoing monitoring of sea surface temperature variability could help to provide early warning of threats to marine ecosystems.”

About Earth Changes Media w/ Mitch Battros

Mitch Battros is a scientific journalist who is highly respected in both the scientific and spiritual communities due to his unique ability to bridge the gap between modern science and ancient text. Founded in 1995 – Earth Changes TV was born with Battros as its creator and chief editor for his syndicated television show. In 2003, he switched to a weekly radio show as Earth Changes Media. ECM quickly found its way in becoming a top source for news and discoveries in the scientific fields of astrophysics, space weather, earth science, and ancient text. Seeing the need to venture beyond the Sun-Earth connection, in 2016 Battros advanced his studies which incorporates our galaxy Milky Way - and its seemingly rhythmic cycles directly connected to our Solar System, Sun, and Earth driven by the source of charged particles such as galactic cosmic rays, gamma rays, and solar rays. Now, "Science Of Cycles" is the vehicle which brings the latest cutting-edge discoveries confirming his published Equation.
