Sarnia vs Turku

Informations

Sarnia is a city in Southwestern Ontario, Canada, with a 2016 population of 71,594. It is the largest city on Lake Huron and in Lambton County. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque Le Griffon north against the nearly four-knot current of the St. Clair River.This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying cargoes of grain and petroleum products. The natural port and the salt caverns that exist in the surrounding areas, together with the oil discovered in nearby Oil Springs in 1858, led to the dramatic growth of the petroleum industry in this area.

Because Oil Springs was the first place in Canada and North America to drill commercially for oil, the knowledge that was acquired there resulted in oil drillers from Sarnia travelling the world teaching other enterprises and nations how to drill for oil.The complex of refining and chemical companies is called Chemical Valley and located south of downtown Sarnia. In 2011 the city had the highest level of particulates air pollution of any Canadian city, but it has since dropped to rank 30th in this hazard. About 60 percent of the particulate matter comes from industries and polluters in the neighbouring United States.Lake Huron is cooler than the air in summer and warmer than the air in winter; therefore, it moderates Sarnia's humid continental climate, making temperature extremes of hot and cold less evident. In the winter, Sarnia occasionally experiences lake-effect snow from Arctic air blowing across the warmer waters of Lake Huron and condensing to form snow squalls over land.

Turku ( TOOR-koo; Finnish: [ˈturku] (listen); Swedish: Åbo [ˈǒːbʊ] (listen), Finland Swedish: [ˈoːbu] (listen); Latin: Aboa; Russian: Турку, formerly Або) is a city and former capital on the southwest coast of Finland at the mouth of the Aura River, in the region of Finland Proper (Varsinais-Suomi) and the former Turku and Pori Province (Turun ja Porin lääni; 1634–1997). The region was originally called Suomi (Finland), which later became the name for the whole country. As of 30 September 2018, the population of Turku was 191,499 making it the sixth largest city in Finland after Helsinki, Espoo, Tampere, Vantaa and Oulu. There were 330,192 inhabitants living in the Turku sub-region, ranking it as the third largest urban area in Finland after the Greater Helsinki area and Tampere sub-region. The city is officially bilingual as 5.2 percent of its population identify Swedish as a mother-tongue.It is unknown when Turku gained city rights. The Pope first mentioned the town Aboa in his Bulla in 1229 and the year is now used as the foundation year of Turku. Turku is the oldest city in Finland, and served as the most important city of the eastern part of the Kingdom of Sweden (modern-day Finland). After the Finnish war, Finland became an autonomous grand duchy of the Russian Empire in 1809. Turku lost its status as capital of the Grand Duchy in 1812, when Tsar Alexander I of Russia decided to move the capital to Helsinki.

It was only after the last great fire in 1827 that most governmental institutions were moved to Helsinki along with the Royal Academy of Turku (Turun Akatemia) founded in 1640, which then became the University of Helsinki. Turku continued to be the most populous city in Finland until the end of the 1840s, and it remains the regional capital and an important business and cultural center and port. Because of its long history, it has been the site of many important events, and has extensively influenced Finnish history. The history of the country is closely linked to Turku, the former capital. Along with Tallinn, the capital city of Estonia, Turku was designated the European Capital of Culture for 2011. In 1996, it was declared the official Christmas City of Finland. Also, Turku has been officially declared the "Food Capital of Finland", because it holds a number of Finland's oldest and high-qualited restaurants, including the country's top-rated Indian restaurant Delhi Darbar, and a historically famous fish market held twice a year.Due to its location, Turku is a notable commercial and passenger seaport with over three million passengers traveling through the Port of Turku each year to Stockholm and Mariehamn.
