AbstractThis thesis examines the sea trade between the city of Vasa in Österbotten and the county of Västerbotten in Sweden during the period 1809-1830 and aims to determine how the division of Sweden into two countries in 1809 affected the trade. In order to systematically treat data, a theoretical concept of quantitative network analysis is applied. The primary source material consists of accounts from the custom house in Vasa.The results show that the sea trade had resumed within a year after the Treaty of Fredrikshamn in 1809. The sea trade over Kvarken was predominated by agents from Västerbotten, particularly from Umeå. In 1810, the first boat departed from Umeå to Vasa, a trend which would come to accelerate up to a culmination in 1816 as regards the number of boats and the quantity of goods. The sea trade later experienced a successive decline between 1817 and 1830, which marks the end of the studied period. The agents which travelled over Kvarken were initially peasants, albeit over time these were successively replaced by skippers and other sea-faring professionals. Concerning shipped goods, the study also concludes that the main products shipped from Västerbotten to Vasa were fish and fabrics. Conversely, the main products shipped from Vasa to Västerbotten were cattle and grains.Even though the trade had importance for the Vasa region in terms of supplying important staple goods, the trade with Västerbotten represented just a small percentage of the total goods shipped through Vasa port. The trades swift recovery after the division is partly attributed to the good relations between Sweden and Russia after the Treaty of Fredrikshamn (1809); but also the favorable tariff policy between the two countries. Another contributing factor to the increase in trade between Vasa and Västerbotten at the time may have been the limitation of trade with continental Europe as a result of the ongoing Napoleonic Wars.

The advanced technology has influenced every industry including the automotive sector, communication industry, maritime, and electronic sector. Through a qualitative research method this study aims to explore the possibility of employing unmanned and automated sea vessels in sea trade along with its major benefits and challenges to get a clearer view of where and when unmanned and automated sea vessels is going to change the future of the maritime sector. It also includes the willingness of ship owners and cargo operators to adopt the new technology. The findings indicate the existence of autonomous ships in the coming 10-years but legislation needs to be adopted for making the autonomous shipping possible for international trade. The conclusion being that autonomous ships are the future of the shipping or maritime industry. Cost-effectiveness is the potential benefit while legislation has been considered a major challenge. / Avancerad teknologi har påverkat varenda industi inkluderat bilindustrin, kommunikation, sjöfartsindustrin och den elektroniska sektorn. Genom en kvalitativ undersökningsmetodförsöker den här studien utforska möjligheten av användningen av obemannadeochautonoma fartyg inom handelsflottan tillsammans med dess största fördelar ochutmaningar för att få en bättre bild av var och när autonoma fartyg kommer att bliframtiden för den maritima sektorn. Den inkluderar även villigheten från redareochlastägare att ta till sig den nya teknologin. Resultaten visar på en trolighet att nybyggeninom en 10 års period kommer vara planerade men lagstiftningen måste ändras för attgöra autonoma båtar möjlig för internationell handel. Slutsatsen är att autonomafartygär framtiden för sjöfarten och den maritima industrin där kostnadseffektivitetenär denstörsta fördelen och lagstiftning anses vara den största utmaningen
