Seasonal variability of tides in the Arctic Seas

Abstract

The long-term mean harmonic and nonharmonic tidal characteristics and their seasonal changes were estimated for six tide-gauge stations in the Russian Arctic (White, Laptev and Chukchi Seas). The estimation is based on hourly sea level observations. Significant differences in the seasonal variations of the amplitudes and phases of major tidal constituents were found between the White Sea and the seas of the Siberian continental shelf. In the White Sea, they do not exceed 9%, while in the Siberian continental shelf seas they reach 63%. The results of calculations of the tidal extreme characteristics, such as the mean spring range and the maximum possible tidal range, are given.

Influence of Estuarine Tidal Mixing on Structure and Spatial Scales of Large River Plumes

“…Tides in the Khatanga Gulf are among the largest in the Eurasian part of the Arctic Ocean. Maximal tidal range in different part of the gulf is 1-2 m [Pavlov et al, 1996;Kulikov et al, 2018]. The largest tidal velocities up to 1.4-1.7 m/s were registered at the straits that connect the outer part of the gulf with the inner part and the open sea, which are described above [Korovkin and Antonov, 1938;Pavlov et al, 1996].…”

The Influence of Arctic Landfast Ice on Seasonal Modulation of the M2 Tide

“…Altimeter‐derived seasonal modulation was compared to earlier studies that computed seasonal variations in M 2 amplitudes based on water level records from tide gauges or temporary pressure sensors. Comparable seasonal changes in amplitude and phase (magnitude and timing) were observed along the Russian coast (Kulikov et al., 2018); in most of Hudson Bay (Kleptsova & Pietrzak, 2018; St‐Laurent et al., 2008) and in the Labrador Sea and Canadian archipelago (Kleptsova & Pietrzak, 2018). In northern Hudson Bay, altimeter‐derived differences between March and September amplitudes were more positive than those derived from in situ data (St‐Laurent et al., 2008).…”

The Effect of Sea Ice on Tidal Propagation in the Kitikmeot Sea, Canadian Arctic Archipelago

“…Varying Parameters of Sea Ice for the 11 FVCOM Simulations frequencies, likely due to the variability of the tidal amplitudes caused by sea ice (Kulikov et al, 2018). As with the power spectra, harmonic analysis of seasonally modulated constituents calculated over a year will place energy into harmonics of neighboring frequencies.…”

“…In the Kara Sea, the M 2 tidal amplitude is damped by about 7% during ice cover (Volkov et al, 2002). M 2 amplitude seasonal changes in the White Sea are also small; both winter increases and decreases of 7%-9% are observed (Kulikov et al, 2018). Very large seasonal changes in M 2 elevation…”

“…Very large seasonal changes in M 2 elevation were observed in the Laptev sea (43% increase) and Chukchi Sea (63% decrease) linked to seasonal shifts of amphidromic systems at the nearby islands (Kulikov et al., 2018). These regions also exhibit significant seasonal variation in phase (Kulikov et al., 2018). Within the Canadian Arctic, M 2 tidal amplitudes are damped during the winter by about 10% in western Hudson Bay and up to 40% in the eastern Hudson Bay and James Bay (Prinsenberg, 1988; St‐Laurent et al., 2008), while tidal increases were observed in western Hudson Strait (St‐Laurent et al., 2008).…”
