Hurricanes

With the recent weather events in the Atlantic region, some of our student assistants got curious… We dug into Robertson Library, UPEI‘s website, www.islandnewspapers.ca , and found this gem. This piece on hurricanes was published September 12th, 1958 in the Charlottetown Guardian newspaper.

HURRICANES

National Geographic News

“In a single second, a typical hurricane releases more energy than several atomic bombs. In less than an hour, it expends more energy than 50 years’ production of electric power in the United States. 

In a day, a hurricane can lift two billion tons of water from the ocean and hurl them back on land and sea as torrential rains. Packing a force of a half-trillion horsepower, it can scythe a path of death and destruction 580 miles broad. 

For all its terrible strength, a hurricane is born of little but warm, moist air caught in a calm in the tropics and given a twist to set it spinning. Gradually it becomes a large revolving storm, accompanied by violent winds, heavy rains, and high waves and tides. 

FAVOR SEPTEMBER

The same type of storm is called a “typhoon” in the China Sea, a “baguio” in the Philippines, and a “cyclone” in the Bay of Bengal, the National Geographic Society says. 

Hurricanes may form at any time of year, but most come in August, September, and October. In an average year, two tropical storms bring hurricane force winds to the Atlantic Seaboard and the Gulf Coast. 

The United States Weather Bureau can predict with increasing precision the areas likely to be hardest hit by a hurricane.

The value of warning was pointed up by two hurricanes that passed over Lake Okeechobee in Southern Florida. The first struck in 1928 before the Joint Hurricane Warning System had been set up. Deaths totaled 1,836. The second- with equal winds- followed virtually the same path, but killed only two persons. The chief difference was a warning that gave people time to evacuate. 

Scientists have not yet devised a way to stop or divert a hurricane, but researchers have learned how to manufacture miniature cyclonic storms in the laboratory. By studying these pint-sized hurricanes, scientists hope to learn more about how a hurricane develops and behaves. Knowledge gained in this and other researches- such as radar tracking and flying into the actual storms- should lead to even more accurate predictions and perhaps, some day, to control. 

BLOWN OFF TRACKS

Weathermen already know that hurricanes usually move from low to higher latitudes with increasing speed, size, and intensity. Winds of a hurricane topple trees, bowl over houses, and even blow trains off their tracks. But the storm takes its greatest toll by drowning. As the hurricane moves forward, it may pile up enormous waves which cover low-lying beaches and islands.”

Glen Property Visit, July 2019

On Wednesday 18 July, some of the GeoREACH Lab team members took a trip into the field (literally) to visit Bill and Elizabeth Glen’s land in the Bonshaw area of Lot 30, Prince Edward Island. Bill and Elizabeth are well known in PEI genealogical and historical circles, and Bill was formerly a forester with the PEI Provincial Government. He now serves as a forest and woodland consultant, and he co-authored a chapter with Josh MacFadyen in the University of Calgary Press collection on Historical GIS Research in Canada. The Glens have been on their property since the early 1980s, and they were able to provide some real insight into how the land has changed over the last forty years, including how they managed the forest, fields, and hedgerows!

The team has studied Lot 30 extensively using aerial photos and historical maps on GIS. We were excited to explore the real area that we have been examining from above for the last several months. It reminded us that our research is much bigger than just a computer screen! We could see the changes that have occurred in the land since the aerial photos that we are currently studying were taken in 1968, before the implementation of the Comprehensive Development Plan (for more on that see this post). Some of these changes include hedgerow planting, the appearance of new homes, and a new nut orchard on the property.

While on this excursion, we learned about hedgerow and woodlot composition, as well as the importance of biodiversity and climate change adaptability in wooded areas. White spruce (what we use to plant most of our hedgerows) is incredibly vulnerable to slight shifts in climate! Bill also showed us a hydraulic pump that dates back to 1890, which he still uses to pump water to the tank for his nut orchard. The GeoREACH team would like to thank Bill and Elizabeth Glen for having us to their home and sharing their knowledge of land-use change on Prince Edward Island.

The PEI Comprehensive Development Plan: A Timeline

The signing of the Comprehensive Development Plan (CDP) in 1969 was one of the most influential events in the modernization of Prince Edward Island. The developmental plan offered wide-sweeping changes to the island’s economy, infrastructure, and education that still affect the province to this day.

Here at the GeoREACH laboratory, it is one of our goals to help others understand how exactly the CDP affected life on the Island, both in the past and today. For this reason, we have created a full, comprehensive timeline of the CDP, from the events leading to the CDP’s formation to its eventual conclusion in 1984. We hope that it is helpful in understanding this significant time period. Enjoy!

Newsy Notes

Newsy Farm Notes (later just Newsy Notes) was a column written by Islander Blythe Hurst under the pen name “Agricola.” It was published by The Guardian PEI newspaper (then known as The Guardian of the Gulf or The Charlottetown Guardian) in the mid-20th century. This column covered a large variety of topics, including farm news, nature profiles, historical tidbits, tips and tricks, and some opinion pieces among other things. It was fairly popular, and ran for four decades, from the 1920s-1960s.

Hurst was a source of botanical knowledge for Islanders, and his column and other publications represent a valuable collection of local ecological knowledge from the early twentieth century. He immigrated to PEI in the 1910s, living in Brackley from 1930 until his death in 1951. Hurst, was the author of A New Flora of Prince Edward Island, published in 1941 by the Guardian and available in full text on Island Lives. In her history of Brackley Beach Women’s Institute, Ellen Cudmore writes that local residents “who had a rare or unidentified insect would travel from all across the Island to consult Mr. Hurst. He had insects and butterflies pinned, identified and mounted in green velvet show cases enclosed in glass. He also had an extensive library and would search his reference books until he found a satisfactory answer for each inquiry.”[1]

Keep checking back, as we will be uploading some excerpts from the column!

Mapping Land Use on PEI in the 1960s

by Choyce Chappell, UPEI
29 May, 2019

The poster that I produced at the UPEI GeoREACH Lab in the 2019 winter semester offers a unique glimpse into PEI’s past. Nick Scott, another GeoREACH lab member, found and scanned a map detailing the approximate property boundaries of almost all of PEI in the 1960s. We called this map the Beaulieu Map, after Andrée Beaulieu, a federal researcher with the Department of Energy, Mines and Resources. The Beaulieu map was based on aerial photos from the early 1960s, so while the plot sizes were not exactly accurate, they were extremely close for a hand-drawn map. This was a fascinating find. The map was created to support the Comprehensive Development Plan (CDP), one of the central research subjects of Dr. MacFadyen’s GeoREACH Lab at UPEI.

I began this part of the project began by exploring avenues to try and use processes that would automatically digitize the map into a format that would work with the GIS softwares that the lab uses. Unfortunately, due a number of factors, such as limitations with GIS tools, creases in the map from folding, and inaccuracies in the map, we were unable to do so. As a result, I switched over to sampling six  townships, and manually digitizing them. The result initially contained small errors in geometry, so we tried to minimize those using several GIS tools and by excluding slivers and small parcels from the analysis.

Getting the poster and preliminary analysis ready the Environmental Science Atlantic Conference was a real time crunch, and the first version of the poster had little quantitative data and little in the way of visual supplements. Over the following few weeks, the final poster (see above) was refined and presented to members of the GeoREACH Lab and other members of the UPEI community. I added added and rearranged new information, I completed additional quantitative analysis, and I added and edited more images to accurately reflect the research process and the story we uncovered.

To perform the quantitative analysis, we categorized properties by the size of the parcel (a smallest size, three mid-sizes, and a largest size), and analysed land use by five dominant categories (cleared land, forested land, harvested clear-cuts; harvested partial cuts; and reverting land). Using this data, we were able to make some generalizations about ongoing trends among farms according to their property size, location, and land use. This is a unique glimpse into the lives of Prince Edward Islanders in the 1960s, finding many stories that could not have been told with other forms of historical analysis.

The true success of this work is knowing how much further it can go, and what it means for the future. This work is preliminary to digitizing the whole map, and can be used as a template for such a project. Additionally, the work can be used to see how much the CDP affected the land use and cover change, and the soil quality, of PEI over time, or to analyse the land use of properties by water shed, county, topographic features, and more. Even though I am no longer with them, I’m excited to see what the GeoREACH lab does with this work!
