Tidal plume generation around a promontory: effects on nutrient concentrations and primary productivity

Flow‐field observations of a tidally driven island wake used by marine mammals in the Bay of Fundy, Canada

“…John et al. (1992) and St. John and Pond (1992) found that primary productivity downstream from a persistent headland wake was enhanced.…”

“…At fine spatial scales, headland wakes in the waters of British Columbia increased local levels of nitrate by an order of magnitude and doubled local phosphate levels through increased vertical mixing downstream in the wake (St. John and Pond, 1992).…”

Abundance and distribution of the harbour porpoise (Phocoena phocoena) on the north coast of Anglesey, Wales, UK

“…Johnston et al (2005) showed that some harbour porpoises were closely associated to fine-scale oceanographic features such as tidal races and eddies and associated aggregation of prey species. These features have been shown to increase nutrient levels, stimulate primary production (St John & Pond, 1992; St John et al , 1992) and aggregate plankton and weak nekton (Wolanski & Hamner, 1988; Mann & Lazier, 1996). This creates localized aggregations of small consumers such as schooling fish which results in concentrated patches of prey for marine predators (Johnston et al , 2005).…”

The turbulent dynamics of anticyclonic submesoscale headland wakes

“…Coastal bathymetric features shape near-shore ocean circulations and directly impact physical and biological processes unique to these areas, such as dispersion of nutrients, dissolved pollutants, floating organisms, and sediment (St John and Pond 1992;Wang et al 1999;Bastos et al 2003;Nencioli et al 2011;Ben Hamza et al 2015). Importantly for the present study, as sites of flowbathymetry interactions, they also tend to be locations of intensive turbulence generation (Jalali and Sarkar 2017;Johnston et al 2019;Capó et al 2023;Radko 2023;Mashayek 2023;Whitley and Wenegrat 2024), leading to elevated rates of kinetic energy (KE) dissipation and buoyancy mixing (Munk and Wunsch 1998;Nikurashin and Ferrari 2011;Melet et al 2013;McDougall and Ferrari 2017;Polzin and McDougall 2022).…”
