-------------------------------------------------------------------- Z - F I D S N E W S L E T T E R No. 44 13 Mar 2019 Editor: Andy Smith (email andy@zfids.org.uk) Website: www.zfids.org.uk -------------------------------------------------------------------- News from Halley ---------------- At the end of February, after the 2018/19 summer season, the station personnel departed but automated systems continued the scientific observations. The station commander, Rich Warren, has sent the following report: "The Halley summer season 2018-19 is over and the door into C module has been swung shut for the final time until reoccupation next summer. Departing at the end of February following a very successful season was bittersweet, as this marks the beginning of the third consecutive winter with no wintering team. That being said, we have taken a step in a bright new direction with the successful commission of the micro-turbine generator; a unit with an automated fuelling system which will provide power to a suite of instruments throughout the nine unmanned winter months. The prestigious long-term atmospheric and space weather datasets for which Halley is renowned are, once again, being acquired outside of the Antarctic summer for the first time since 2016. This includes but are not limited to, a mechanically automated Dobson spectrophotometer, Clean Air Section instruments, an array of riometers and magnetometers, the meteorology tower instruments. The acquisition of winter science data is essential for cementing Halley as a platform for Antarctic science, and I am delighted to say that thus far, the micro-turbine is running well and all systems are go. This project represents the excellence and integration of every department at Halley this season. From the mechanical systems which deliver the fuel, to the communications network that allow us to remotely monitor and communicate with every feature of the turbine (not to mention transfer of the data back to Cambridge), every aspect has been made with robustness and multiple back-ups in mind to ensure it runs safely while the station is unoccupied. It signifies a truly interdepartmental collaboration and is a hallmark of the season, with a summer team of only 36 this year, we have relied on each other more than ever to deliver what in recent years, has taken 60-70 people to accomplish. Another key feature of this season has been the continued propagation and widening of both Chasm 1 to the west (propagating north), and Halloween Crack to the north (propagating east). As of mid-March, the west Brunt is connected to the rest of the Brunt Ice Shelf by a sliver of 4.5km of ice. All eyes (as well as an ApRES, 16 'Lifetime of Halley' stations and a huge amount of satellite imagery) have been watching it ceaselessly, though it still remains attached for now. While this has been said daily since 2017, it surely cannot be long until it breaks off, and from the fresh ice edge we will be able to examine the possibility of a ship call in future years in the absence of the newly adrift Creeks. With a ship call bringing a resupply of food and fuel, and with to-be-determined stability in the ice shelf that remains, we can look at returning Halley to a more familiar set up in the foreseeable future. Until then, I hope you'll all join me in looking with optimism and excitement to next year and beyond." Many thanks to Rich for keeping us informed of latest developments. Sadly, as usual, there are deaths to announce. John Bradford ------------- John Bradford died in December 2018. He was one of the geophysicists at Halley in 1977 and 1978 and after that, worked for the Rutherford Appleton Lab. JB was a popular base member and always attended the 1977 reunions organised by Ken Lax. Jim Blackie ------------- Jim died on 11th December 2018 at the age of 81. He was the wintering physicist at Halley in 1960. Lyn Blackie writes: "He completed an M.Sc. on his auroral work at Halley. We were married in February 1962 and left for Kenya later that year, supposedly for 2 years which became nearly 10! He went from the 'heavens' at Halley to 'water' as his job was now catchment research. This took him to all 3 East African countries. Jim returned to the UK in 1971 to work at the Institute of Hydrology where he worked till his retirement in 1998. Although his work was mainly in the UK and Channel Islands, his 'itchy' feet were eased by several 3-month returns to Kenya plus less extended spells in India, Pakistan, New Zealand, Chile and the Czech Republic. He led a very active retirement continuing with his beloved allotment, long distance walks and orienteering until COPD caught up with him and gradually ruined his mobility." Lyn has sent some of Jim's photos which are included on the Z-Fids 1960 webpage. Z-fids website www.zfids.org.uk ------------------------------- A landmark was reached in November 2018 when the website, which has now been running since June 2001, recorded its 100,000th visit. A page has been added on the Ferguson farm tractors, modified with added tracks, which were used in the first few years before they were replaced by Muskegs in 1961. www.zfids.org.uk/1960/ferguson.htm The first two pictures on the page (monochrome) were taken by Jim Blackie. But who took the two colour pictures? And what is on the sledge being towed in the second picture? Lewis Juckes (geologist 1964-1965) has written about an expedition above the roofs of the Halley-I buildings, to find the source of a leak. This was published in the BAS Club Magazine No. 79, but Lewis has asked me to republish it here. Find it from the link on the 1964 page. Ian Jones (Met. physicist 1982 and 1983) has put together a YouTube video of his time on base, entitled "Not all beer and icicles". See the 1982 page. Vince Carter has sent in a satellite image of the Brunt Ice Shelf from Polar View (2018+ page). This clearly shows Chasm No 1 and the Hallowe'en Crack. Since July 2008 the website has been archived from time to time in the UK Web Archive. See link on the Z-Fids home page. Contributions to the website are welcome at any time. Take a look at the page(s) corresponding to the time when you were at Halley. Did anything special or unusual happen which could be mentioned? Do you have any anecdotes or interesting photos? British Antarctic Oral History Project -------------------------------------- Of the 286 Oral History interviews held in BAS Archives, 231 have now been transcribed by our team of volunteers. 88 of the interviews have been published on the BAS Club website (link on the zfids home page) and more are expected to be published later this year. You don't need to be a BAS Club member to see them. There are links on the Z-Fids website to the interviews featuring Halley people (See the General Index under Oral history recordings). Here are a couple of extracts from the interviews: Martin Pinder (cook 1970): Radio hamming ---------------------------------------- "You needed 10 words a minute receiving and transmitting to get your amateur licence which was issued from the Falklands. When I went down to Halley, there was an ionosphericist (I only know him as Graunch). I can’t remember his name now [Keith Chappell]. Anyhow because they had to send up things into the ionosphere, and then receive, bounce them back, so they had a good receiver there which you could pick up the World Service. Then he said ‘Why don’t we get a transmitter out of the old base?’ So we trogged off down there with a skidoo and a sledge, put an A-frame up with a Handy-Hauler. We used a skidoo with a pulley system, crawled down through this (it was about forty feet I think), went down on a Dexion ladder, and crawled through ice- covered little tunnels to get to the radio shack. This was Halley-I, and the ice crystals in there were absolutely fantastic. I took loads of black & white photos of them. Anyway we dragged this thing along. It was only hauling it up we realised how heavy it was. We used a skidoo and it actually buckled the A-frame that we’d erected but luckily we had just got it to the top, took it back to the Beastie Hut, hauled it down the shaft into there. Graunch then converted it from being AM to go out on Single Sideband and I used to spend hours there. You’d do ‘CQ, CQ’ and so anyone but everybody wants to talk, make contact with somebody in the Antarctic." NERC copyright, reproduced courtesy of BAS Archives Service. Archives ref AD6/24/1/129. Andy Spearey (Tractor Mechanic 1979): Austere conditions at Halley-III ---------------------------------------------------------------------- "There were only two generators when there should really have been three, so blackouts at Halley III were a regular occurrence. The generators were running very very close to their maximum loads and it only needed somebody just to put one light extra on and that was it: it tripped it all out. So consequently of course, none of the pit rooms were heated; the whole pit room block was unheated. So you would record -12 degrees in the winter months in your pit room. You didn’t mess around in your pit room; you certainly didn’t spend any time in there. The lounge was only heated from Friday night to Sunday night; it wasn’t heated the rest of the time so that got cold as well, though because it was in the living block with the kitchen, it did get some heat from the kitchen so it didn’t get really really cold, but you wouldn’t want to go and sit in there. So it was a fairly austere sort of a place." NERC copyright, reproduced courtesy of BAS Archives Service. Archives ref AD6/24/1/205. ----- Many thanks to all contributors to this Newsletter.
