Expedition 7 home from Antarctica
The sewaiventh Antarctic expedition from the Otago Space Physics group returned to Dunedin on Thursday after a very productive week on the ice Prof. Craig Rodger and Dr. James Brundell left on the scheduled day, and returned to Christchurch only ~5 hours later than planned. They spent almost exactly one week in Antarctica, in an intensive mission to repair the AARDDVARK antenna located near Scott Base. This year the weather was kind, giving them a lot of good quality working time [20 November 2014].
Electron Precipitation Drives Ozone Losses
Energetic electron precipitation (EEP) from the Earth’s outer radiation belt continuously affects the chemical composition of the polar mesosphere. EEP can contribute to catalytic ozone loss in the mesosphere through ionization and enhanced production of odd hydrogen. However, the long-term mesospheric ozone variability caused by EEP has not been quantified or confirmed to date. We recently showed in Nature Communications, using observations from three different satellite instruments, that EEP events strongly affect ozone at 60–80 km, leading to extremely large (up to 90%) short-term ozone depletion. This impact is comparable to that of large, but much less frequent, solar proton events. On solar cycle timescales, we find that EEP causes ozone variations of up to 34% at 70–80 km. With such a magnitude, it is reasonable to suspect that EEP could be an important part of solar influence on the atmosphere and climate system.
The Nature Communications article was the result of a collaboration between the Finnish Meteorological Institute, University of Otago and British Antarctic Survey. The article produced press releases from FMI and Otago University, and lead to a number of articles in news papers, including the Otago Daily Times and the New Zealand Herland. Craig was interviewed on National Radio, which can be listened to online [17 October 2014].
Expedition 7 planning maintenance trip to Antarctica
The seventh Antarctic expedition from the Otago Space Physics group is preparing for their trip South. Prof Craig Rodger is the event manager for Expedition 7, while Dr James Brundell is the event leader (these are the names used by Antarctica New Zealand for the roles we fill). The main goal of our travel is to repair long-term damage to our antenna, which was been in place since December 2008 but has slowly suffered in the high winds at Arrival Heights. The team is currently scheduled to travel to Scott Base on Wednesday 12 November 2017 for a 7-day highly intensive working period. The logistics support, comprising air transport, accommodation, and all other on-ice support is provided through Antarctica New Zealand Event K060.
James and Craig are heading to Scott Base to work on Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. They also comprised the Expedition One team who deployed this radio receiver in December 2008; this is James' 6th visit to Antarctica and Craig's third. Expedition Seven will also gather high resolution data, undertake calibrations and make VLF radio noise observations. While planning is well underway, both Craig and James have a few other tasks to complete first – Craig leaves to China this Friday and then will travel to Finnish Lapland, while James is currently in Brazil having attended the V Brazilian Symposium on Space Geophysics and Aeronomy & IV Forum for Research and Innovation.

Craig went too as he was co-organising two sessions, had a separate invited talk, a couple of oral presentations and a couple of posters, plus was the official New Zealand delegate. Craig and Aaron took the day off and had a tour of Tiananmen Square in central Beijing, plus travelled out to see the Mutianyu section of the Great Wall of China. [25 August 2014]
Alex and Jason Visit Waihola School
Ian Whittaker and Alex Schwertheim visited Waihola District School and undertook Space Physics outreach activities to the primary school class there. The students, aged between 4 and 11, at this rural school were participants in demonstrations on how big and cold our solar system is. Ian and Alex showed practical demonstrations of how the Sun warms the Earth, how the Moon affects tides on the Earth and the phases of the Moon. The students then were part of a human solar system and saw a demonstration on why astronaut spacesuits are necessary. Ian and Alex were also requested to judge a cake making competition from the students - an activity they were happy to perform! This visit has appeared on the Blog page for Waihola School Room 2, including the students impressions of the activities. [22 August 2014]

James and Craig going back to Canada
This Friday Dr James Brundell and Prof. Craig J. Rodger will be heading to Canada to visit some of the AARDDVARK receiver sites. We will go to St John's initially, to the AARDDVARK receiver there which is on the site of the St. John's Magnetic Observatory. After a couple of days working there we will travel to Ottawa (visiting Natural Resources Canada Space Weather Forecast Centre), then Edmonton (Space Physics Group at the University of Alberta). At this point we split up. Craig will head to Calgary (visiting the University of Calgary), while James will leave Canada and go to Seattle (visiting the University of Washington's Department of Earth and Space Sciences). As part of this trip we will be returning to the Ministik Lake AARDDVARK antenna which has certainly had a very hard life. Since our last visit in July 2013 (see the news bulletin below) the data quality has been pretty good, but it has continued to be a somewhat mid-behaved [15 May 2014].
Space Physics Material launched on the Science Learning Hub
Craig was filmed back in late March 2013 by a team from the New Zealand Science Learning Hub, who were putting together a new resource called "Gases and Plasmas". The Science Learning Hub provides resources for teachers of school years 2-10 and is funded by the Ministry of Business, Innovation and Employment. The Gases and Plasmas context includes multiple content from the Space Physics group, including radiation belt and space weather research, Red Sprites, our WWLLN lightning research, and overviews on plasmas and studying Physics. And more, actually [29 April 2014].

Mark Clilverd joins us for more than 3 months
Each year Mark Clilverd from the British Antarctic Survey comes to visit the Otago Space Physics group - this very long-standing collaboration has produced a lot of science, and influenced a lot of student projects. This year Mark came to Dunedin for more than 3 months, having a sabbatical" in our group. All of the Space Physics group, staff and students, worked alongside Mark in this time period - a bunch of our scientific questions have been clarified. But now Mark is heading homewards, leaving us on Monday next week [7 April 2014].
SCOSTEP launches the VarSITI programme
Scientific Committee on Solar Terrestrial Physics (SCOSTEP) launched its new scientific program VarSITI (Variability of the Sun and Its Terrestrial Impact) on Monday 13 January 2014. VarSITI is an international interdisciplinary research program that will run for next five years. The VarSITI program is established after a collective effort by the international scientific community over the past year. It will focus on four major themes: solar magnetism and extreme events, Earth impacting solar transients, magnetospheric changes, and consequences and processes in Earth's atmosphere. In order to make progress on these themes, four scientific projects have been defined, which are headed by international experts.
One of the 4 projects inside the VarSITI programme is SPeCIMEN (Specification and Prediction of the Coupled Inner-Magnetospheric Environment), which is lead by Otago academic Assoc. Prof. Craig J. Rodger and UCLA-researcher Dr. Jacob Bortnik. More details at the VarSITI website, the SCOSTEP website, or from this YouTube movie associated with the VarSITI programme launch [13 January 2014].
Craig Rodger promoted to Professor!

Expedition 6 home from Antarctica
The sixth Antarctic expedition from the Otago Space Physics group returned to Dunedin on Sunday after a cold time. While Dr. James Brundell and Space Physics PhD student Aaron Hendry. While theywere expected to come back to New Zealand on the Wednesday before, a series of weather-related delays kept them on the ice for several extra days. Nonetheless, they made it home, safe and well. Craig received a text message confirming this as he, Kathy and Jason were taking the train away from Najoya airport, Japan (see previous item) [17 November 2013].
Jason, Kathy, and Craig off to Japan
Tomorrow a group of us leave Dunedin, heading for the International CAWSES-II Symposium in Nagoya, Japan. Space Physics MSc students Kathy Cresswell-Moorcock and Jason Neal along with Assoc. Prof. Craig Rodger have multiple presentations to give over the 5-day meeting. Jason and Kathy have not been out of New Zealand before, so this is a very exciting opportunity [14 November 2013].
Expedition 6 wind-blown in Antarctica
The sixth Antarctic expedition from the Otago Space Physics group are currently working in and around Scott Base. This year our team has gone south earlier than normal, at the request of Antarctica New Zealand. This has produced some new challenges for the team, with colder temperatures and higher winds up around the New Zealand lab at Arrival Heights where our experiment is located. The picture below shows Space Physics PhD student Aaron Hendry beside our experiments antenna during an inspection of the equipment undertaken today. Dr James Brundell, the event leader, and Aaron have achieved quite a few of the primary goals, and will likely be returning to New Zealand this Thursday, just one day later than originally planned [11 November 2013]
Expedition 6 prepares to depart for Antarctica
The sixth Antarctic expedition from the Otago Space Physics group is preparing for their trip South. Dr James Brundell, the event leader, has been preparing with Space Physics PhD student Aaron Hendry. They will be testing new monitoring equipment as we investigate the possibility of new recording sites around Ross Island.

We will go to Ottawa initially (visiting Natural Resources Canada Space Weather Forecast Centre), then Edmonton (Space Physics Group at the University of Alberta) and finally fly south to Seattle (visiting the University of Washington's Department of Earth and Space Sciences). As part of this trip we will be returning to the Ministik Lake AARDDVARK antenna which has certainly had a very hardlife. Since November it has mostly behaved, and we hope to find it in good conition [24 July 2013].
Our SPeCIMEN plan for SCOSTEP accepted!
Scientific Committee on Solar Terrestrial Physics (SCOSTEP) is an interdisciplinary body of the International Council for Science (ICSU). SCOSTEP runs international interdisciplinary scientific programs and promotes solar-terrestrial physics research. We recently helped prepare a white paper to submit to SCOSTEP, suggesting a project for their 2014-2018 Science Programme. Our project was named SPeCIMEN: Specification and Prediction of the Coupled Inner Magnetospheric Environment.
After a panel meeting in Bern, Switzerland, SCOSTEP selected our project to be one of the 3 core SCOSTEP programmes which will run in that 5-year period. Assoc. Prof. Craig J. Rodger is part of the Executive Committee which will oversee this project. He also supported the preperation of another white paper which was combined with others to produce another project for SCOSTEP's plan, ROSMIC: Role of the Sun and the Middle Atmosphere/Thermosphere/Ionosphere in Climate.
We are thrilled to hear SCOSTEP recognises the importance of our scientfic directions, and the new collaborations this will spark [14 May 2013].

Update from Otago Space Physics Antarctic Expedition 5
The two-man team making up the fifth Antarctic expedition from the Otago Space Physics group to Antarctica travelled to Christchurch on Sunday to be issued their Antarctic clothing. On Monday morning Dr James Brundell, the event leader, sent us a SMS alerting us they were delayed about 1 hour, but by 706am that morning he SMSed "On plane!" and by Monday afternoon James and Dr Ian Whittaker were emailing us back in Dunedin to confirm they had arrived at Scott Base. After a base tour they are scheduled to have dinner, their bags arriving at 7pm, and Antarctic Field Skills training starting at 845am Tuesday morning. The logistics support for Expedition 5 is provided through Antarctica New Zealand Event K060. [26 November 2012].
Expedition 5 prepares to depart for Antarctica
The fifth Antarctic expedition from the Otago Space Physics group is preparing for their trip South. Dr James Brundell, the event leader, is currently working alongside Dr Ian Whittaker, to undertaken noise tests and become familiar with some of the experimental equipment they will use when south. The team is scheduled to travel to Scott Base on Monday 26 November 2012 for a eight-day intensive working period. The logistics support, comprising air transport, accommodation, and all other on-ice support is provided through Antarctica New Zealand Event K060.
James and Ian are heading to Scott Base to work on Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. James was one of the two man Space Physics team who deployed this radio receiver in December 2008. The main aim for Expedition 5 is to move our experiment from one room of the New Zealand lab at Arrival Heights into a neighbouring room. In late 2010 a powerful LIDAR experiment was installed by US researchers in the room our experiment was located. The new LIDAR experiment has led to some issues for our experiment, which we hope to mitigate by moving next door. Ian and James will also undertake measurements of the VLF noise in and around the Arrival Heights area. Interested? You can read more at this webpage [13 November 2012]
More repairs made to Alberta AARDDVARK receiver
In early August 2012, the signal at the Ministik Lake AARDDVARK antenna suddenly dropped out - less than 3 weeks after we had travelled to Canada to repair it. We quickly identified the problem had been caused by a near-by lightning strike, which must have damaged the experiments electronics. Today, 9 November 2012 (NZ time) staff from the Space Physics Group from the University of Alberta went out to Ministik Lake and replaced the preamp - and the data is now flowing again. The new preamp has been upgraded to withstand lightning better in the future. We hope. This instrument has certainly had a very hard time, detailed on this webpage. [9 November 2012].
Craig and Aaron in Brazil
In early September 2012 Assoc. Prof. Craig Rodger and Space Physics PhD student Aaron Hendry travelled to Sao Paulo (Brazil) to attend the 5th VERSIM workshop, the first time the workshop had been held outside of Europe. Because of the transport links between New Zealand and Brazil they flew via the United States, which allowed us to visit the Udvar Hazy Center (Smithsonian Air and Space Museum). There is a particularly nice image on the space physics image collection of Aaron Hendry standing in front of the Space Shuttle Discovery (OV-103). During the VERSIM workshop one of Craig's presentations was recorded and put up on You Tube. People often comment on Craig's presentation style, and this is an example of him in action [6 September 2012].
Repairs made to Alberta AARDDVARK receiver
In mid-July 2012 Dr James Brundell and Assoc. Prof. Craig J. Rodger travelled to Edmonton in Canada to repair AARDDVARK antenna installed at Ministik Lake, Alberta, Canada. The antenna was installed in October 2010, and is located at a field site of the Space Physics Group from the University of Alberta. The Ministik AARDDVARK antenna also provides data to the world wide lightning location network, WWLLN. This instrument has had a hard time, detailed on this webpage. It has suffered from computer failure and the attention of the local wildlife. Craig and James headed out to repair and upgrade the instrument, so it is better suited to make continuous measurements in the next few years to support the RBSP and DSX spacecraft missions, and the BARREL balloon campaigns [21 July 2012].

It includes multiple institutions worldwide but is led by Dr. Janos Lichtenberger of Eötvös University (ELTE), Budapest - Hungary, who has visited us twice before in Dunedin. We will be strongly involved in Work Package 4, which will make use of AARDDVARK data, and Assoc. Prof. Rodger is the leader of Work Package 5, dissemination. The Otago support is €352,357 (out of €1,972,269 total), and will fund a PostDoc and a PhD student in the Otago Space Physics group. More information at the PLASMON website. [12 January 2011].
Space Physics Hosts Ratu Sir Kamisese Mara Fellow
From January-April 2011 the Otago Space Physics group is hosting Assoc. Prof. Sushil Kumar of the University of the South Pacific (Fiji). Assoc. Prof. Kumar is visiting the as the 2011 Ratu Sir Kamisese Mara Fellow, an award which funds staff from the University of the South Pacific to work for up to 3 months with researchers from Otago. Assoc. Prof. Kumar plans to work with us on lightning, red sprites, and subionospheric VLF propagation. [10 January 2011].
In the footsteps of Scott
In November 2010 an international two-man team will be travelling to Antarctica to visit the Otago Space Physics Group's experiment. The team is scheduled to travel to Scott Base on Wednesday 24 November 2010 for a brief seven-day visit to the ice. Dr Craig Rodger, the event leader, will accompany British Antarctic Survey scientist Dr Mark Clilverd. The logistics support, comprising air transport, accommodation, and all other on-ice support is provided through Antarctica New Zealand Event K060.
The researchers are travelling to Antarctica to undertake maintenance on Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. The Space Physics group deployed this radio receiver in December 2008. Feedback from the Antarctica New Zealand Scott Base technicians have identified damage to our antenna cables, likely caused by the strong winds at Arrival Heights. Mark and Craig will be replacing these cables, checking for other damage, gathering up the data for the last year, and undertaking calibration of the gear.

New AARDDVARK site added to network
Dr Craig Rodger travelled to Alberta, Canada, to add a new AARDDVARK antenna to the network of VLF receivers. The antenna was installed at Lake Ministik, a CARISMA field site of the Space Physics Group, University of Alberta. Dr Craig Rodger and Dr Mark Clilverd (British Antarctic Survey) installed the new receiving equipment during a week in mid-October. The antenna will feed measurements to the AARDDVARK and WWLLN networks. [17 October 2010]
Space Physics wins Marsden support
The Space Physics research group has been awarded a $700,000 project grant from the New Zealand Marsden Fund. This grant will support the research of Otago Staff Dr. Craig Rodger and Assoc. Prof. Neil Thomson plus Dr. Adian McDonald of the University of Canterbury for 3-years starting March 2011. You can read more about our proposed research from this webpage. [24 September 2010]
Craig Rodger gives Plenary Lecture at SAIP
Dr Craig Rodger travelled to South Africa to give a Plenary Lecture at the 55th Annual Conference of the South African Institute of Physics, which was held in Pretoria, South Africa. While in South Africa was hosted by the Hermanus Magnetic Observatory, and also gave seminars at the University of Cape Town and the University of KwaZulu-Natal. [7 October 2010]
Rob completes his MSc
Space Physics MSc student Rob McCormick has now been formally advised of his mark, having completed her project. Rob was working on an improved fullwave computation model to describe subionospheric VLF propagation. Well done Rob! He has now moved on to working for the Otago DHB. [21 September 2010]
Mark leaves after his 2010 visit
Dr. Mark Clilverd, visiting the group from the British Antarctic Survey has now headed out of Dunedin, on his way back home. Mark spent 2.5 weeks with us, primarily working with Dr. Craig Rodger, but also Assoc Prof. Neil Thomson, and students Rory Gamble and Sarah Dietrich. Mark is a regular visitor to Dunedin, and some of the visit was used so he and Craig could plan their joint activities in 2010. We hope to see him again for Summer next year. We enjoyed some walks around Dunedin, some dinners out, and of course a lot of Scientific Discussion. [24 January 2010].
Sarah completes her MSc
Space Physics MSc student Sarah Dietrich has now been formally advised of her mark, having completed her project. Sarah was comparing relativistic electron microburst observations from our ground-based AARDDVARK data with satellite measurements. She plans to graduate in May 2010. Well done Sarah! She is currently working inside the group as part of a Summer Bursary. [22 January 2010]
Intrepid Journey - part 2
Dr James Brundell and Space Physics PhD student Mr Rory Gamble returned from Antarctica on 12 December 2009. Their entire journey went to plan, with all the goals of the expedition met. Event K060 is looking good for the next year of data gathering from Scott Base! [22 December 2009]
The Space Physics Group of the Physics Department is about to send two researchers to Antarctica. The two-man team is scheduled to travel to Scott Base on Wednesday 2 December 2009 for a brief nine-day visit to the ice. Dr James Brundell, the event leader, will accompany Space Physics PhD student Mr Rory Gamble. The team's transport and on-ice support will be provided through Antarctica New Zealand Event K060.
The researchers are travelling to Antarctica to gather data from Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. The Space Physics group deployed this radio receiver in December 2008, and a big part of this year's trip is to see how the antenna and electronics have survived a year in the very high winds and cold temperatures up at the Heights.

Scientists find solar footprints in the snow
A new study by the Space Physics group and their collaborators shows that the magnetic space storms that create the northern and southern lights could lead to a better understanding of natural temperature variations in the polar regions. Surprisingly, large temperature changes may be linked to auroral activity. More information is available from this webpage. [4 November 2009]
