“…Separating the integrated impacts of rainfall and ocean mixing on TC‐induced SST and Chla wakes is complex and will require further work. Coastal upwelling can also affect TC‐induced SST and Chla wakes in limited areas (e.g., Scrosati 2020) and deserves additional study.…”

Tropical cyclones provide an important source of ocean mixing, bringing cold, nutrient‐rich water to the surface and triggering phytoplankton blooms. Here, we show significant increases in global tropical cyclone‐induced sea surface temperature cooling and surface chlorophyll‐a concentration of 0.05°C and 3.7 × 10−3 mg m−3 per decade over the past 20–35 years. The trends have been driven primarily by an increase in the intensity of strong tropical cyclones. The increase in chlorophyll‐a concentration has been, on average, 1.6% per decade in oligotrophic areas during the tropical cyclone season, in contrast to a decrease of 0.1% per decade during the other months. This tropical cyclone‐induced increase has partially mitigated the overall decline in primary production under climate change.

“…Thus, on the one hand, intertidal conditions are influenced by the seasonal changes in sea surface temperature (SST), which can be pronounced on temperate shores, which display warm waters in summer and cold waters in winter. On the other hand, an even greater degree of thermal variation can occur at hourly scales once intertidal habitats become exposed to the air at low tide, especially on hot days in spring and summer (Watt and Scrosati, 2013;Lathlean et al, 2014;Umanzor et al, 2017) and cold days in winter (Scrosati and Ellrich, 2018a).…”

“…Temperature data are available for surface ocean waters worldwide (Fay and McKinley, 2014;Banzon et al, 2016;Freeman and Lovenduski, 2016;Aulicino et al, 2018;Yun et al, 2019). However, data on intertidal temperature are considerably less common in terms of both spatial and temporal coverage (Lathlean et al, 2014;Umanzor et al, 2017;Scrosati and Ellrich, 2018a). This is especially true for waveexposed intertidal habitats, as remote sensing methods that are commonly used for open waters (e.g., satellites) cannot capture the quick, localized temperature changes caused by tides and waves.…”

“…Wave-exposed rocky intertidal habitats are common along the Canadian coast in Nova Scotia, as this coast faces the open Atlantic Ocean. Several studies have investigated the ecology of these environments (Minchinton and Scheibling, 1991;Scheibling, 1998, 2001;Scrosati and Heaven, 2007;Arribas et al, 2014;Molis et al, 2015;Ellrich and Scrosati, 2016;Scrosati andEllrich, 2018b, 2019;Scrosati, 2020a, b). However, because of their research goals, intertidal temperature was either not measured or analyzed for a few locations or for limited time periods.…”

Abstract. Intertidal habitats are unique because they spend alternating periods of submergence (at high tide) and emergence (at low tide) every day. Thus, intertidal temperature is mainly driven by sea surface temperature (SST) during high tides and by air temperature during low tides. Because of that, the switch from high to low tides and vice versa can determine rapid changes in intertidal thermal conditions. On cold-temperate shores, which are characterized by cold winters and warm summers, intertidal thermal conditions can also change considerably with seasons. Despite this uniqueness, knowledge on intertidal temperature dynamics is more limited than for open seas. This is especially true for wave-exposed intertidal habitats, which, in addition to the unique properties described above, are also characterized by wave splash being able to moderate intertidal thermal extremes during low tides. To address this knowledge gap, we measured temperature every half hour during a period of 5.5 years (2014–2019) at nine wave-exposed rocky intertidal locations spanning 415 km of the Atlantic coast of Nova Scotia, Canada. This data set is freely available from the figshare online repository (Scrosati and Ellrich, 2020a; https://doi.org/10.6084/m9.figshare.12462065.v1). We summarize the main properties of this data set by focusing on location-wise values of daily maximum and minimum temperature and daily SST, which we make freely available as a separate data set in figshare (Scrosati et al., 2020; https://doi.org/10.6084/m9.figshare.12453374.v1). Overall, this cold-temperate coast exhibited a wide annual SST range, from a lowest overall value of −1.8 ∘C in winter to a highest overall value of 22.8 ∘C in summer. In addition, the latitudinal SST trend along this coast experienced a reversal from winter (when SST increased southwards) to summer (when SST decreased southwards), seemingly driven by alongshore differences in summer coastal upwelling. Daily temperature maxima and minima were more extreme, as expected from their occurrence during low tides, ranging from a lowest overall value of −16.3 ∘C in winter to a highest overall value of 41.2 ∘C in summer. Daily maximum temperature in summer varied little along the coast, while daily minimum temperature in winter increased southwards. This data set is the first of its kind for the Atlantic Canadian coast and exemplifies in detail how intertidal temperature varies in wave-exposed environments on a cold-temperate coast.

“…Results are compared with the SCS model derived by NF21 for 10 other hurricanes that propagated through the region from 2011-2019. Several researchers have documented the impact of Hurricane Dorian on the marine environment (e.g., Ezer, 2020;Scrosati, 2020), and anthropogenic influences/slowing translation speeds on its extreme rainfall (Kossin, 2018;Reed et al, 2021;Yamaguchi et al, 2020). As Dorian translated east of the Lucayan Archipelago (consisting of the sovereign Bahamas and United Kingdom-dependent Turks and Caicos) in the Atlantic Ocean, the severity of the hurricane may have been compounded by the occurrence of nonlinear interactions of the archipelago's narrow and steep carbonate shelf with hurricane-forced waves, storm tide, and it variability due to elongated arching coastlines as seen for Hurricane Joaquin in 2015 (Fedele et al, 2017;Sahoo et al, 2019).…”
