The wave spectrum in archipelagos

Jan-Victor Björkqvist, Heidi Pettersson, and Kimmo K. Kahma

Data sets

Wave and wind data from the Helsinki archipelago and Gulf of Finland J.-V. Björkqvist, H. Pettersson, and K. Kahma https://doi.org/10.5281/zenodo.3482304

Short summary

In this paper we present wave buoy measurements from the Finnish archipelago. The properties of the waves inside the archipelago differed from waves in the open sea because of the sheltering effect of the islands. In the archipelago the highest single wave was, on average, only 1.58 times the significant wave height, which is lower than what is predicted by previous research. A more robust way to calculate the wave frequency in the complex archipelago conditions was proposed.
