| Summary: | Ocean tides are a vital component of global ocean circulation. In the Arctic Ocean, tides affect ocean circulation and sea ice dynamics and thermodynamics. Significant advances have been made in global ocean tide models; however, difficulties remain in the Arctic due to the poorly-mapped bottom topography, the dynamical influence of sea ice, and limitations on satellite altimetry measurements due to the high latitudes and presence of sea ice. The limited network of in-situ tide gauges in the Arctic is an additional factor. In-situ measurements from tide gauges or ocean bottom pressure sensors are crucial sources of information that can be used to understand the spatial variability of tides and validate the advances made in modelled estimates. Global in-situ tidal constituent databases contain a limited number of observations in the Arctic, with, for example, TICON-3 containing 111 above 60°N and 21 above 70°N, with the distribution of these measurements mainly being around North America. Here, we present the ... |
