Physical rather than biotic factors set the lower limit of mussel beds in a horizontal rocky intertidal platform
2022, Journal of Experimental Marine Biology and EcologyCitation Excerpt :The maximum water velocities in the upper and lower platform were recorded during a 24-h period (16–17 May 2018) with dynamometers. The spring of each dynamometer was tied to a drag element (a practice golf ball) and assembled following Bell and Denny (1994). Four dynamometers were installed per platform level.
Unmanned aerial vehicle technology to assess the state of threatened biogenic formations: The vermetid reefs of mediterranean intertidal rocky coasts
2021, Estuarine, Coastal and Shelf ScienceCitation Excerpt :In the tidal area, in particular, the turbulence of wave motion along the rocky shore creates both unfavorable (e.g., limitation of larval settlement, decrease of fauna diversity for dislodgement) and favorable (e.g., distribution of larvae, supply of planktonic food) effects (Lewis 1968). Among the various approaches to detect these effects (e.g., dynamometers as in Jones and Demetropoulos, 1968; plastic golf ball attached to a spring, as in Bell and Denny, 1994), some studies have dealt with water motion measurement using the loss of weight of fixed plaster Paris balls (Calcium sulphate balls; Doty, 1971; Muus, 1968). This method was widely used in the past, for example, to detect the relation between water motion and zooplankton availability to corals (Wellington, 1982) and the hydrodynamic regime of water motion affecting Posidonia oceanica beds (Gambi et al., 1989), and also for its field operational simplicity and minimal cost.

2019, Estuarine, Coastal and Shelf ScienceCitation Excerpt :Therefore, in order to characterize the extent of hydrodynamics variability at the metric scale and associated effects on intertidal biota, direct measurements are necessary. However, such measurements are still very rare for intertidal environments (Jones and Demetropoulos, 1968; Bell and Denny, 1994; O'Donnell and Denny, 2008). In situ hydrodynamical measurements are generally carried out using large (>30 cm) pressure transducers in the intertidal zone, including wave height assessment (Autret et al., 2016; Suanez et al., 2019).
Knots and tangles weaken kelp fronds while increasing drag forces and epifauna on the kelp
2018, Journal of Experimental Marine Biology and EcologyCitation Excerpt :Each frond was towed at only one velocity (0.3, 0.4, 0.5, 0.6 or 1.0 m s−1), which was in the range of ambient water velocities experienced by the kelp (Friedland and Denny, 1995; Gaylord et al., 2008). A spring scale (Ohaus Models 8001-MN, 8261-M, 8263-M, Ohaus, Pine Brook, NJ) recorded the maximum force with which the frond resisted the movement through the water (Bell and Denny, 1994). Three replicate measurements of drag forces were made at the tow velocity for each unknotted frond.
