Short project summary

The project aims to initiate a new collaboration between the two research groups through a joint study into how energy is dissipated into the upper atmosphere through interaction between the Sun’s magnetic field (IMF) and the Earth’s magnetic field. Ultra Low Frequency (ULF) waves and turbulence manifest themselves as periodic fluctuations in the atmospheric signatures of this energy deposition (such as temperature and density changes) and in the Earth’s magnetic field. By monitoring the frequency, magnitude and location of the waves on the ground it is possible to investigate the complex plasma processes and interactions happening in the Earth’s ionosphere/magnetosphere system. The most intense wave activity in the ULF frequency range (from fractions of mHz to few Hz) is persistently observed at high latitudes. They are identifiable in ground based instrumentation such as magnetic field monitoring stations (magnetometers), optical equipment and radars. The instrumentation located on Svalbard at Longyearbyen, Barentsburg, Hornsund and Ny-Ålesund thus allows a unique opportunity to study these waves over long time periods at high latitudes.

This connection between the IMF and the Earth’s magnetic fields produces two main areas of interest which have two different physical methods of interaction.  These will be the focus of the collaborative projects. In addition, the project will also involve stays on Svalbard for researchers from IPE as well as joint fieldwork trips to Barentsburg. Researchers from UNIS will travel to IPE for joint workshops.

By monitoring changes in the Earth’s upper atmosphere (ionosphere), which is magnetically connected to the magnetosphere, we can understand the process of energy transfer between the two systems (adapted from Kivelson and Russel 1995).

March/April 2017
Professor Vyacheslav Pilipenko from IPE and Dr. Vladimir Belakhovskii from The Polar Geophysical Institute (PGI) in Apatity visited researchers at UNIS for two weeks.  During that time Professor Pilipenko gave a lecture to the research staff and student in the group about the project.  The group visited the KHO and SuperDARN radar during their stay. A field excursion to Barentsberg was also arranged for Professor Pilipenko and Dr. Belakhovskii, along with Professor Lorentzen and Assoc. Professor Baddeley, from UNIS.  The party travelled to and from Barentsburg by snow mobile and spent overnight in Barentsburg.  A visit to the geophysical observatory (operated by PGI) and also the Kola Science Centre (operated by the Russian Academy of Sciences) was also arranged by Dr. Belakhovskii. A particular focus of the meeting was looking at dayside ULF waves observed on Svalbard (using ground magnetometer and photometer data) and how they relate to similar structures observed at lower latitudes. By comparing the frequency and structure of the waves it is possible to ascertain information regarding the shape of the Earth’s magnetic field and in particular if it is ‘open’ to that of the Interplanetary Magnetic Field (IMF) from the Sun (allowing particles to enter into the Earth’s upper atmosphere from the Sun) or ‘closed’. Debate exists within the community however as to the location of the ‘open’ part of the magnetic field and it’s relation to the ULF waves.  This is one problem which this project hopes to address.

Prof. Vyacheslav Pilipenko delivers a lecture to the staff and student of the Space Physics Group at UNIS. Students from the Masters courses AGF-301 and AGF-304 also attended.

Dr. Vladimir Belakhovskii provides a summary of his recent work to the research group utilizing Tromsø and Svalbard EISCAT data.
