“…For example, Wang et al (2017) used multiple linear regression of key discriminant variables (sea-ice concentration, stratospheric circulation and sea-surface temperature) and obtained forecast skill (r) of 0.69-0.71. Combined, these advances suggest that skillful prediction of seasonal and decadal coastal vulnerability may be possible (Colman et al, 2011;Dobrynin et al, 2019), where forecasts of climate indices may provide a valuable tool for managing risk to society due to extreme winter-wave events, wave directional variability and corresponding geomorphological change at the coast.…”

Improved understanding and awareness of how our coasts and beaches will evolve over a range of time scales (years to decades) is critical for effective and sustainable management of our coastal infrastructure. While coastal erosion is already a problem globally (Luijendijk et al., 2018;Mentaschi et al., 2018), climate change can also affect the primary drivers of coastal change, impacting local sea-level changes (Cazenave et al., 2014) and increased storminess in some regions of the world (Scaife, Spangehl, et al., 2012;Zappa et al., 2013). Globally, increased sea-level rise will likely result in increased erosion (Le Cozannet et al., 2016), and increased frequency and intensity of coastal flooding along low-lying coasts (e.g., Vousdoukas et al., 2018). Regionally, atmospheric processes described by teleconnection patterns like the North

“…Other studies [24] have also shown that, over the years, episodes of extreme waves have become more frequent in the Atlantic Ocean, and therefore studies such as ours are very necessary when designing a maritime infrastructure. A study of wave heights in the Atlantic Ocean [25], covering the period from 1982 to 2017, studies the seasonal prediction in all areas of the Atlantic. In its conclusions it states that, especially in the mid-Atlantic ridge (where the Canary Islands are located), the prediction of heights has improved greatly over the years and that the data currently provided are very accurate for marine designs.…”

Maritime Climate in the Canary Islands and its Implications for the Construction of Coastal Infrastructures

Islands are isolated systems that depend on maritime trade for their subsistence. Efficient, durable and structurally reliable port infrastructures are essential for the economic and social development of islands. However, not all port infrastructures are designed in the same way. They can vary, depending on whether they are built on continental land, built on non-volcanic islands or built on volcanic oceanic islands (such as the Canary Islands, Spain). The latter islands are the subject of this study due to their specific features, construction difficulties and the importance of sound maritime infrastructures. The maritime climate of an area consists of the wave and storm regimes that affect it and, from these, the coastal dynamics and coastal formations of that area can be studied. For this reason, historical data were collated on significant directional wave heights from 1958 to 2015 from several WANA-SIMAR points in the virtual buoy network of State Ports of Spain located near the Canary Islands. These data have been studied to obtain the maximum directional wave heights (Hs) at each point. With this analysis, we have obtained useful summary tables to calculate wave height by a graphic method that transforms the distribution function into a line drawn on probabilistic paper, using reduced variables. This enables adjustments to be made by linear regression and minimum square methods to facilitate planning and design of maritime infrastructures in a reliable way.

“…The study area is located on the west coast of Ireland (9.26 • -10.79 • W, 52.33 • -53.26 • N), as is shown for the Atlantic in Figure 1. It is located in the westerlies and ocean current movements are affected by the North Atlantic Oscillation and low-pressure system [27,28]. Figure 1b shows that the bathymetry in the study area ranges from 0-140 m, and the isobaths nearshore are roughly parallel to the coastline.…”

“…Compared to traditional current measuring instruments, it has several advantages: its high spatial and temporal resolution and wide area of coverage, and that it is on an all-weather system. HFR senses fields of sea surface currents, waves, and sea surface winds using Bragg scattering and Doppler frequency shift effects produced by the interactions between high-frequency radio waves and the sea surface [27,29].…”

Research on coastal ocean circulation patterns over long time periods is significant for various marine endeavors: environmental protection, coastal engineering construction, and marine renewable energy extraction. Based on sea surface current data remotely observed using a shore-based high frequency radar (HFR) system for one year (2016), spatiotemporal characteristics of surface flow fields of sea surface flow fields along the west coast of Ireland are studied using harmonic analysis, rotary spectral analysis and representative flow fields over different seasons and the whole year. Coastal surface currents in the study area are strongly affected by tidal dynamics of the M2 constituent, showing significant characteristics of regular semidiurnal tide, such as M2 and S2. The energy spectrum distribution indicates that the tidal constituents M2 and S2 are the dominant periodic energy constituents in a counterclockwise spectrum, which mainly presents rotating flow; the representative diurnal tidal constituents is the constituent K1, and its energy spectrum distribution is mainly clockwise. A comparison between probable maximum current velocity (PMCV) and measured maximum current velocity (MMCV) is presented. It shows that although tidal current characteristics in the study area are significant, the main driving force of the currents at the time of the maximum currents is wind energy. These results provide new insights into a region of huge societal potential at early stages of sustainable economic exploitation where few data currently exist.
