In their study, the scientists found that the "drift" of the geomagnetic field correlated with which route the salmon chose.
It is derived from measurements made at a number of stations world-wide of the variation of the geomagnetic field due to currents flowing in the earth's ionosphere and, to a lesser extent, in the earth's magnetosphere" (Northwest Research Associates, n.

The scientific objective of the mission is to proceed with the most complete study ever of the geomagnetic field and its evolution over the years.
gradients and ionospheric scintillations) - reproduce small-scale effects such as TIDs or depletions and other disturbances - understand better the effects of geomagnetic storms in the ionosphere - adapt to changes in geomagnetic field and solar cycle - improve prediction and forecasting capabilities for ionospheric effects - understand the effects of such effects on GNSS systems Extensive measurements over solar maximum will be carried out during the MONITOR activity under the GNSS Evolutions Programme and other experiments from external organisations.
For the study, Dickman and his colleague Le-Qing Wu placed 7 pigeons in a pitch-black room and used a 3D coil system to cancel out the planet's natural geomagnetic field and generate a tunable, artificial magnetic field inside the room.
It seems that the Bz tilted southwards for some time when the interplanetary magnetic field interacted with the geomagnetic field.
However, this replication shows the lowest payout rate exactly at the time of the full moon, which Radin explained with increased geomagnetic field values at this time (Radin, 1997, p.
Unknown Factors In Chronobiology", presented by Professor Alexander Dubrov, provides an analysis of data published in the papers of leading chronobiologists and biosymmentrists, demonstrating that the variations of the geomagnetic field and tide-forming forces of the Moon and Sun provide the basis for the homeostasis in living beings.
