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.
Instrumentation utilized during the study:
- Kjell Henriksen Observatory
- EISCAT Svalbard Radar
- Barentsburg Geophysical Observatory
- SuperDARN radar network
- IMAGE magnetometer network
The project organized a scientific session at the annual meeting of the European Geophysical Union (EGU) which is held in Vienna (https://egu2018.eu/) The meeting is attended by over 15 000 scientists and covers a wide range of topics under the umbrella of geophysical sciences. The session (ST3.6 – ULF waves and turbulence in the auroral oval and polar cap regions: New horizons in multi-instrument observations) received 11 abstracts from scientists in Russia, Norway, UK, USA and Finland. In addition to fruitful scientific discussions, it also allowed us to show case our collaborative project to an international audience. Smaller meetings were held during the week to discuss ongoing and possible future projects. A session dinner was also held with the contributing abstract authors.
Dr. Olga Kozyreva from IPE presented work from the project at the recent IAGA (International Association of Geomagnetism and Aeronomy) joint Assembly http://www.iapso-iamas-iaga2017.com/ in Cape Town, South Africa. Her presentation was entitled ‘In search of ground image of the magnetopause surface mode: Multi-instrument observations at Svalbard’.
Assoc. Prof Lisa Baddeley and Prof. Dag Lorentzen made a second trip to the Schmidt Institute of Physics of the Earth in Moscow. Whilst in Moscow, they met with the Director of the Nuclear Physics Institute of Moscow State University, Professor Mikhail Panasyuk, to discuss possible future collaborations between the research groups. A special focus of possible collaborations was the recently launched LOMONOSOV satellite. Assoc. Prof. Baddeley and Prof. Lorentzen also gave an invited seminar at Moscow State University (Space physics studies and education in Svalbard) before embarking on a guided tour of the university campus and facilities. A particular highlight of the visit was a tour of the main University building, which is the highest of the seven Stalinist skyscrapers of Moscow.
Assoc. Prof Lisa Baddeley, Prof. Dag Lorentzen and Prof. Vyacheslav Pilipenko from IPE also met with Dr. Krasnoperov at the Geophysical Centre of the Russian Academy of Sciences to discuss the ongoing reseach project and also education possibilities on Svalbard for Russian students: http://gcras.ru/news.php?n=153
A visit was also arranged to the Museum of the Cosmonauts which showcases the history of the Soviet Space program from its beginnings with the Sputnik program to the modern Russian space program with the new Vostochny Cosmodrome.
Work continued on several of the project work packages and a manuscript has now been submitted for review to Annales Geophysicae.
Dr. Olga Kozyreva and PhD student Nataliya Nosikova from IPE visited UNIS for a small workshop. Progress regarding the development of the algorithm to identify the ‘open’ geomagnetic field lines using photometer data from the KHO (including the new dataset from the 2016/2017 season) was discussed. A new research project following on from the work published by Yagova et al. (2017) was also discussed. Nataliya and Assoc. Prof. Lisa Baddeley also utilized the GUISDAP (Grand Unified Incoherent Scatter Design and Analysis Package) software installed on the UNIS computers to analyse and identify datasets from the EISCAT Svalbard Radar which could be used in Work Package 3.
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.
Work from the project was presented at the VarSITI (Variability of the Sun and Its Terrestrial Impact) General Symposium in Bulgaria.
2 researchers, Professor Lorentzen and Assoc. Professor Baddeley, from UNIS visited IPE in Moscow. In addition to small workshops with scientists from the institute and the Polar Geophysical Institute, Professor Lorentzen and Assoc. Professor Baddeley gave an invited seminar at the Russian Academy of Sciences. The visit also included a private tour of the museum dedicated to Russian achievements in space research.
Work from the project was presented at the joint EISCAT / optical meeting held in Hermanus, South Africa.
Dr. Olga Kozyreva and Nataliya Nosikova from IPE visited UNIS as part of the project. This was the first exchange visit of the project. A number of data workshops and meetings were held. Presentations were also given detailing the work presented at the EGU meeting and also in preparation for the up and coming meetings in September.
Work from the project was presented at the annual European Geophysical Union (EGU) meeting in Vienna by Nataliya Nosikova from IPE.
