“…While in some studies settlement and larval supply appear to be correlated 12 (Minchinton and Scheibling, 1991;Yund et al, 1991;Hurlbut, 1992;Jeffery and Underwood, 13 2000; Ross, 2001;Ma, 2005), other studies find no correlation (Miron et al, 1995;Olivier et al, 14 2000;Porri et al, 2006;Rilov et al, 2008), suggesting caution in interpreting settlement as proxy 15 for larval supply. 16…”

“…In other studies, coarse-to large-scale hydrodynamic processes 19 are correlated to time series of larval settlement, but larval concentrations in the water are not 20 measured (e.g., Bertness et al, 1996;Jacinto and Cruz, 2008). Some studies have measured both 21 larval concentrations and settlement (e.g., Jeffery and Underwood, 2000;Ma, 2005;Porri et al, 22 2006;Dudas et al, 2009), and recruitment (e.g., Palma et al, 2006;Rilov et al, 2008), to 1 determine the relationship with hydrodynamics. Modelers have also explored the relationship 2 between large-scale hydrodynamics, larval supply and settlement (e.g., Alexander and 3 Roughgarden, 1996;Guizien et al, 2006;Ayata et al, 2009).…”

“…As larvae are transported from offshore waters to within 10 -100's meters of the shore, delivery 12 of larvae to the bottom will be influenced by hydrodynamic forces such as surface gravity waves, 13 through oscillatory flows, shoaling and breaking, and wave induced along-shore and cross-shore 14 flows (e.g., Miller and Emlet, 1997;Porri et al, 2006;Rilov et al, 2008;Dudas et al, 2009). A 15 relationship between larval supply and settlement is most likely to be detected when larval 16 supply is measured within a few meters or less of the settlement substrate (e.g., Otaíza, 1989;17 Jeffery and Underwood, 2000;Todd et al, 2006;Tremblay et al, 2007).…”

“…These differences, however, are sometimes smoothed out by 6 settlement larval behavior (Pineda, 1994a). Another approach has been to place settlement 7 substrates on mooring lines (e.g., Dobrestov and Miron, 2001;Rilov et al, 2008;Dudas et al, 8 2009). Comparison of hydrodynamics on fixed versus moving settlement substrates has not been 9 made although increased biomass of barnacles on rotating panels compared to fixed panels was 10 attributed to differences in water flow (Glasby, 2001).…”

“…The proportion of competent to non competent larvae in larval samples may obscure a supply-13 settlement relationship (Miron et al, 1995;Rilov et al, 2008). Competency can be defined as 14 "the capacity of a developing individual to initiate settlement and complete morphogenic 15 transformation associated with metamorphosis" (Bishop et al, 2006).…”

Marine broadcast spawners have two-phase life cycles, with pelagic larvae and benthic adults. 2 Larval supply and settlement link these two phases and are crucial for the persistence of marine 3 populations. Mainly due to the complexity in sampling larval supply accurately, many 4 researchers use settlement as a proxy for larval supply. Larval supply is a constraining variable 5 for settlement because, without larval supply, there is no settlement. Larval supply and 6 settlement may not be well correlated, however, and settlement may not consistently estimate 7 larval supply. 8This paper explores the argument that larval supply (i.e., larval abundance near settlement sites) 9 may not relate linearly to settlement. We review the relationship between larval supply and 10 settlement, from estimates and biases in larval supply sampling, to non-behavioral and 11 behavioral components, including small-scale hydrodynamics, competency, gregarious behavior, 12 intensification of settlement, lunar periodicity, predation and cannibalism. Physical and structural 13 processes coupled with behavior, such as small-scale hydrodynamics and intensification of 14 settlement, sometimes result in under-or overestimation of larval supply, where it is predicted 15 from a linear relationship with settlement. Although settlement is a function of larval supply, 16 spatial and temporal processes interact with larval behavior to distort the relationship between 17 larval supply and settlement, and when these distortions act consistently in time and space, they 18 cause biased estimates of larval supply from settlement data. 19Most of the examples discussed here suggest that behavior is the main source of the decoupling 20 between larval supply and settlement because larval behavior affects the vertical distribution of 21 3 larvae, the response of larvae to hydrodynamics, intensification of settlement, gregariousness, 1 predation and cannibalism. Thus, larval behavior seems to limit broad generalizations on the 2 regulation of settlement by larval supply. Knowledge of the relationship is further hindered by 3 the lack of a well founded theoretical relationship between the two variables. 4The larval supply-settlement transition may have strong general consequences for population 5 connectivity, since larval supply is a result of larval transport, and settlement constrains 6 recruitment. Thus, measuring larval supply and settlement effectively allows more accurate 7 quantification and understanding of larval transport, recruitment and population connectivity. 8 9 4

Cross‐shore transport of nearshore sediment by river plume frontal pumping

We present a new mechanism for cross‐shore transport of fine sediment from the nearshore to the inner shelf resulting from the onshore propagation of river plume fronts. Onshore frontal propagation is observed in moorings and radar images, which show that fronts penetrate onshore through the nearshore and surf zone, almost to the waterline. During frontal passage a two‐layer counterrotating velocity field characteristic of tidal straining is immediately set up, generating a net offshore flow beneath the plume. The seaward flow at depth carries with it high suspended sediment concentrations, which appear to have been generated by wave resuspension in the nearshore region. These observations describe a mechanism by which vertical density stratification can drive exchange of material between the nearshore region and the inner shelf. To our knowledge these are the first observations of this frontal pumping mechanism, which is expected to play an important role in sediment transport near river mouths.
