Tidal oscillations in the Baltic Sea
TLDR
In this paper, the authors used long-term hourly data from 35 tide gauge stations, including 15 stations in the Gulf of Finland, to examine tidal sea level oscillations of the Baltic Sea.Abstract:
Long-term hourly data from 35 tide gauge stations, including 15 stations in the Gulf of Finland, were used to examine tidal sea level oscillations of the Baltic Sea. High-resolution spectral analysis revealed the well-defined fine structure of tidal peaks with diurnal peaks at most stations being higher than semidiurnal. At some stations (e.g., Narva, Daugava, and Wladyslawowo), high frequency radiational tidal peaks with periods multiple of the solar day (3, 4, 5, 6, and 8 cpd) were detected; the respective oscillations are supposed to be caused by seabreeze winds. Harmonic analysis of tides for individual yearly sea level series followed by vector averaging over the entire observational period was used to estimate the amplitudes and phases of 16 tidal constituents. The maximum tidal oscillations of 17–19 cm were found to be observed in the Gulf of Finland and, first of all, in Neva Bay (in the head of the gulf). Diurnal or mixed diurnal tides are predominant in almost the entire Baltic Sea. The comparison of the observed tides with those theoretically computed showed that the existing numerical models of the main tidal harmonics generally quite accurately reproduce the structure of the tides in the Baltic Sea except for some regions of the Gulf of Bothnia.read more

Multi-criteria evaluation approach to coastal vulnerability index development in micro-tidal low-lying areas
TL;DR: In this paper, the authors developed and implemented an updated set of indicators of coastal vulnerability that characterise relatively low-lying coastal segments with negligible tidal range but affected by substantial storm surges driven by atmospheric factors.

Tides in Three Enclosed Basins: The Baltic, Black, and Caspian Seas
TL;DR: In this article, the formation and predominance of diurnal or semidiurnal tides in these seas appears to depend on the frequency-selective properties of the basins and the diurnal radiational constituent S1 (1 cpd) was found to play an important role in general tidal dynamics.

Blending of satellite and tide gauge sea level observations and its assimilation in a storm surge model of the North Sea and Baltic Sea
TL;DR: In this paper, the authors used a stationary blending method developed by Madsen et al. (2007) to relate the coastal satellite altimetry with corresponding tide gauge measurements, allowing generation of sea level maps whenever tide gauge data are available.

TL;DR: A large number of geophysical processes affecting sea level dynamics and coastal erosion in the Baltic Sea region are observed in many other coastal regions worldwide as discussed by the authors, along with the outstanding number of long data records, makes the Baltic sea a unique laboratory for advancing our knowledge on interactions between processes steering sea level and erosion in a climate change context.

TL;DR: In this paper, 19 years of hourly tide readings at Honolulu, Hawaii and Newlyn, England are analysed without astronomical prejudice as to what frequencies are present, and what are not, thus allowing for background noise.

Sea-Level Changes
TL;DR: The field of oceanography is considered a young science with roots going back only to the first half of the nineteenth century as discussed by the authors, when the first scientific cruise of a modern nature, the famous Challenger Expedition, began its work in the oceans, regarded as the opening year of oceanographic research.
