Abstract

Sea level rise is a topic of global importance and has amplified steadily in recent years. New York City and its adjacent bay have been particularly affected compared to the annual mean of the global rise of 3.4 mm since 1993. At the two sea level stations ‘The Battery’ and ‘Sandy Hook’, the annual increase over the same period even amounts to 3.9 mm and 5.2 mm. In addition to the long-term trend, however, there are fluctuations that mainly occur on smaller time scales within a year. Wind, air pressure and discharge of the Hudson River are influential parameters that are considered in this thesis. The winds from a southwesterly to northwesterly direction have by far the greatest influence lowering the sea level in New York Bay. In contrast, winds from northeast to southeast contribute to an increase in local sea levels. However, their influence is weaker, as the prevailing wind direction is west-northwest. Particularly strong influences can be captured during major storm events such as hurricanes or blizzards. While air pressure has a significant impact as well, this could not be shown for the Hudson River discharge.
