Editor’s note: This is the third in a series of posts considering the intersection between environmental history and the histories of science, technology, and medicine. Previous posts can be found here.
This past January, Stephen Bocking’s “Landscapes of Science” post outlined several themes that “deserve more attention in the environmental history of Canadian science.” His exciting suggestions included examining how different environments impact scientific practices and material cultures, as well as how the use of science in the Canadian North after the Second World War shaped the state’s ability to “administer and exploit the region.”
The Canadian High Arctic provides unique opportunities to examine such questions and pose new ones. I am currently completing a history of the Joint Arctic Weather Stations (JAWS) with Whitney Lackenbauer. The stations were constructed between 1947 and 1950 largely at the behest and design of the American government. Canada and the US collaboratively operated a hub station at Resolute and smaller eight-man satellite stations at Mould Bay, Isachsen, Eureka, and Alert until 1972. Each of these civilian-run stations collected synoptic weather data by making surface observations and by flying weather balloons twice a day carrying radiosondes (which had to be manually tracked) or rawinsondes (which could be tracked via radio-direction finding equipment) to measure temperature, barometric pressure, humidity, and wind direction. The data these stations gathered were crucial to military planning, civilian meteorology, and transatlantic commercial aviation, as well as North America’s agriculture and forestry economies. Apart from the resupply season, these stations had little contact with the south. In fact, aside from a few hair-raising flights during the initial years of operations, aircraft did not land at the satellite stations during the dark period of the year until the 1960s.
My contributions to the book include analyzing how the High Arctic environment affected the stations’ scientific cultures. The JAWS program suggests the need for historians of science and environmental historians to pay more attention to technicians. Most scholarly research focuses on the ideas, activities, and impacts of scientists or engineers with undergraduate or advanced degrees. Other academics have begun to explore how “amateurs” (such as hobbyists) complicated scientists’ authority and contributed to environmental knowledge. Meteorological technicians (not scientists) conducted and encoded the JAWS programs’ synoptic meteorological observations. “Met techs,” as they were known, generally lacked undergraduate (let alone graduate) degrees. They were, however, professionally trained. Canadian Met Techs had to pass two courses offered by the Department of Transport. In the first three-month course, students learned how to conduct surface observations. The top students from this class were eligible to enroll in a rigorous four-month upper air observations course. Neither course included Arctic curriculum. Instead, graduates received this additional operational knowledge via on-the job training at the Joint Arctic Weather Stations from outgoing Met Techs.
JAWS personnel lived in a scientific culture. They valued the powers of observation as well as accuracy, consistency, and repetition. Yet they could not analyze the data they gathered; and they were not indoctrinated to desire the placeless ideal of laboratory cultures. Moreover, Met Techs resided at the stations for a year or more at a time. Scientists, by comparison, typically worked at the stations for weeks or a few months. These differences led JAWS personnel to more readily accept and adapt to local conditions. The JAWS program thus offers the opportunity to compare and contrast the scientific cultures constructed by scientists and technicians in an extreme environment.
When JAWS personnel understood the importance of their activities, only the most extreme situations frustrated their perseverance. At some stations, such as Alert, balloon releases were eased by consistently low wind speeds. At other stations such as Isachsen, however, high winds regularly endangered launches by pushing released balloons sideways, dragging and pulverizing the instrument package across the station grounds. Over time, JAWS personnel used different techniques to ensure successful launches in high winds, but the most common solution was the two-person launch. After filling the weather balloon in the shelter and checking its attached instrument package, one person walked upwind with the radiosonde and waited until his partner released the balloon. He then ran with the radiosonde until the balloon carried its cargo aloft. According to Howard Wessbecher, who served as both a supply clerk at Resolute and then an Executive Officer at Alert in the mid-1950s, “sometimes we tried two, three releases and I’d say… less than 5% of the time we didn’t make it” and have to concede that “hey, we can’t get her up.” In one extreme case, personnel at Isachsen launched five balloons, because the first four “burst upon hitting the sides of the door on the way out” under heavy winds.
Radiosondes, however, were not the only types of balloons used at the stations to make meteorological observations. Smaller pilot balloons were not as revealing as radiosondes, but they were less expensive, simpler to prepare, and useful for measuring cloud ceilings. Like radiosondes / rawinsondes, they could also be used to determine the wind’s direction and speed. Tracking the pibal flights forced observers to sit in a sheltered open-air dome and manipulate a metal theodolite with their bare hands at 30 or even 40 degrees below zero. During the dark period, observers hung a candle or battery-powered light below the pibal to enhance its visibility at altitude. From time to time, the observer would note three or four identical azimuth and elevation readings and realize that he had lost the pibal and was instead fixed on a star. “This always brought about a few curses!!” former Mould Bay and Eureka Met Tech Lowell DeMond subsequently recalled, because a second release was necessary if the balloon had not attained the required minimum altitude.
By the mid-1950s, station personnel began using excuses such as high winds or snow to avoid conducting pibals. Southern cries that the flights were essential led to their strict resumption. By the 1960s, however, the regularity of these flights wavered one again. According to Larry Petznick, who was Isachsen’s OIC from 1964-1965, station personnel continued “to question the value of pibal observations” and wondered “if the useage [sic] and end results from pibals are worth the amount of time and work put into them.” Nevertheless, Petznick assured Canadian and American authorities that “the Pibal program continues to slog on.” This seems to have been the last cry. Personnel who served at the JAWS stations in the late 1960s or early 1970s do not recall launching pilot balloons as part of a synoptic program.
JAWS Met Techs participated in scientific culture, innovated operating procedures that better suited their environments, and contributed to data sets. This culture led them to persevere with a host of environmental observations, including upper air flights, despite often harsh conditions. On rare occasions, however, different understandings about the utility of their activities led them to deviate from the wishes of southern scientists. Met Techs are, of course, not unique to the JAWS program. Canada and the United States employed them at weather stations across both countries. Technicians in other professions and programs also require attention. If social scientists do not recognize the contributions made by these men (and later women), they will struggle to understand the extent and nature of scientific culture, how the practical feasibility of government programs are assessed, and how non-scientists at remote outposts contributed to the expansion of the state.

Well written article. I was one of those Met Techs that ended up posted to JAWS/HAWS station Resolute Bay for a total of 3 tours of duty between 1969 and 1973. I was the Senior Meteorological Technician from sometime in 1970 till August 1971.
About severe weather radiosonde balloon launches… The most common reason for a second launch was the loss of the balloon or instrument by contact with the ground at the moment of launch. The initial launch attempt was scheduled for release about 45 minutes before 0000 or 1200 GMT so that the ascent would be at about mid-flight at those times. If the failure of a launch was due to a balloon burst before the instrument package was physically released by the tech, a 2nd release could be attempted within about 15 minutes by preparing another balloon. If the instrument was damaged on launch, the preparation time for the next launch attempt was more like 45 minutes. A 2nd ascent was also called for if a radiosonde failed to reach 50,000 feet or so. The launch attempts continued until either 3 instruments had been used up or until the GMT+45 minute launch window had expired. The only times I remember failing to get a launch within the launch window was when we could not teach the radiosonde station due to white-out blowing snow conditions.
The balloon inflation buildings were designed with 2 opposite-facing overhead launch doors to increase the probability that a favorable leeward launch direction could be selected based on the wind direction.
2-man launces were preferred in marginal wind conditions with the instrument man running downwind as fast as possible as the balloon man came out of the inflation building. If the wind was too strong for even this, a 1-man launch was attempted using a “launch reel” attached between the balloon and the instrument. The launch reel slowly played out a 60ft string on the instrument side during the first minute or so of the ascent. We also used a more sturdy balloon model with a higher rate of rise for these situations (high winds or precipitation). These were not the preferred balloons for everyday use since they did generally did not get to very high altitudes before bursting.

Hi Louis,
Thank you for providing such a detailed account of the launch workflow!
In high wind conditions, an experienced team could actually attempt more than one release using the same balloon… If the balloon got too far downwind of the man with the instrument and it was obvious that the, if released, the instrument package was going to hit the ground, the instrument man would simply stop and hold onto the instrument. If the balloon then survived the wind pull and did not burst by contact with the ground (snow cover), the balloon man would run downwind, retrieve the stretched out the balloon, walk upwind with the balloon in tow while the instrument man walked downwind and the two would retry the launch. This often worked in winds up to about 30 MPH. Above 30 MPH or so, the observers generally just let that balloon go, prepare another balloon, and launch the saved instrument using a 1-man release with a launch reel. With a 2-man release, the instrument man often resorted to throwing the instrument in the air in the hope that the balloon would gain enough additional altitude before the instrument swung back to the ground on its string.

During all my tours as a Upper Air Met Tech into the Arctic (Hall Beach Aug 66-Aug 67), Fort Chimo (Nov 68-Jan 69), Frobisher Bay (Jan 69-Apr 69), Clyde (Apr 69-July 69), Resolute Bay (Aug 69-Aug 71, Sep 72-Aug73)), I never dwelt upon the fact that I was at an isolated far-northern remote location although I was certainly aware that it was sometimes pretty cold outside. And, obviously, weather observers have to spend some time outside. I liked the work that I did, the people that I worked with, and considered it the adventure of a lifetime. I did not consider the assignments as hardship assignments. The pay was good enough for me to save enough so that, when the time came for me to decide to go to university to pursue a degree in electrical engineering (which was my goal from high school graduation in 1965), I was able to get through university without incurring additional debt and without resorting to help from my family.

Hi Louis. It took me back many years to read your northern adventures. My time with Upper Air overlapped yours but i never got to the high arctic, I started in Chimo in mid 60’s (what a great era to grow up in) I then moved on to Port Harrison, Nitchequon, Manawaki, Sept Iles,
then Frobisher with a three week trip to Hall Beach after which i turned south to the new station at Shelburne with several trips to Sable. I too considered my time there as a treasure to remember The trout fishing at Nitch among the best in the world. People pay thousands to spend a week in such a place and I got paid for it ha ha Thanks again for your trip down memory lane ie……. many times running and heaving that instrument as a last hope.

Linden,
I spent time at many of the upper air stations that you served at: Hall Beach (Aug 1966 – Aug 1967), Maniwaki (July-Nov 1968), Fort Chimo (Nov 1968 – Jan 1969), Frobisher Bay (April-July 1969). I then spent the rest of my upper air career at Resolute Bay (Aug 1969 – Aug 1971, Oct 1972 -Aug 1973). I then went to university and got an electrical engineering dgree in 1976. I retired from a 35-year design career with GE Canada/GE/GE-Toshiba/TMEIC-GE/TMEIC Corp. in July 1974. I thoroughly enjoyed both my met tech career and my engineering career.
I am glad that Daniel and Whitney are documenting the history of the Jaws as the way of life we experienced back then is gone forever, particularly before the availability of satellite communications at Resolute Bay in 1970 or 1971 (I was there when this happened but I can’t remember if it was on my 1st tour or 2nd tour). Who would have imagined back then that both Resolute Bay and Eureka would now have television reception.
Louis
My dates for Frobisher Bay should be Jan-Apr 1969. I was then at Clyde from April to July.

It was interesting reading the comments of Louis and the others of their time working at the sites. I spent the early years of my career with Environment Canada working the sites after Louis and the others but I didn’t arrive in the north until after the Americans left and the stations became wholly Canadian enterprises. I believe I arrived in Isachsen in late 1976 and stayed until spring 1978, just before it closed later that year, moving onto Mould Bay and then Eureka. Like most of us working the sites we are all young and it was more of an adventure than a job. It’s a time I still remember fondly today and enjoy reminiscing with others that also spent time working the various sites in the High Arctic and in fact across the country, working as a met tech and the various iterations of the job. We now have a Facebook group where we keep in touch, post stories and pictures we come across as the Yahoo group is now used less often. One of these days I’ll organize and digitize my slides. When I finally left the Arctic and the HAWS I spent about a year providing leave relief at other upper air sites, visiting Baker Lake, Fort Nelson, Spruce Grove, and Fort Smith before ending up in Big Trout Lake. As an aerological instructor at TCTI in Cornwall I spent time introducing the new aerological computer systems to stations across western and northern Canada. Unlike many others who went on to University and different careers I stayed with the Department to work in a number of positions over a 40+ year career.
Hey Dan, is the book still coming?
