The relationship between concentrations of suspended particulate material and tidal processes in the Irish Sea

Assessing the State of the Pelagic Habitat: A Case Study of Plankton and Its Environment in the Western Irish Sea

“…Smoothed monthly mean sub-surface PAR attenuation in 1992 and 1993 fell from 0.30 m −2 in March to 0.20 m −1 in JuneAugust but had increased to 0.25 m −1 in October (Gowen and Bloomfield, 1996). This is consistent with reports that SPM concentrations decrease in the Irish Sea during the season of stratification, as the material sinks below the pycnocline (Weeks and Simpson, 1990;Weeks et al, 1993). Figure 4 shows euphotic zone depth estimated from remote sensing in 2002-2012 and th-SML thickness for 1992-1996 from Gowen et al (1998b).…”

Characterizing the Composition of Sand and Mud Suspensions in Coastal and Estuarine Environments Using Combined Optical and Acoustic Measurements

“…The larger intratidal variation of SCI at spring tide is likely due to the increased resuspension of sand by stronger currents (Figure 5c) and to the greater advection of mud from nearby intertidal flats at late ebb and LWS, similarly to the observations of Weeks et al. (1993) and Fettweis et al. (1998) at other sites.…”

Sediment dynamics in tidally dominated environments controlled by transport and turbulence: A case study for the East Frisian Wadden Sea

“…This maximum could indicate that the delivery of sediment by the ebb current is constantly increased. This effect is similar to the well known “displacement of gradients of SPM” established in other studies [e.g., Weeks et al , 1993]. The results of the experiment with no advection (NA) do not reveal such a maximum.…”
