“…This indicates that on 18% to 23% of the days in a year conditions existed that could have a negative impact on Bay Anchovy growth and production at vulnerable locations in Mobile Bay. During late fall (November), winter, and early spring (March), the percentage of days that winds exceeded 4 m/s was much higher, averaging ≥70%, and was similar to the results reported by Booth et al (2000). We believe Bay Anchovy in warm-temperate and subtropical estuaries may balance capital breeding, in which compensatory feeding takes place in advance of breeding so that reproduction initially may be financed from stored energetic capital, with income breeding, in which reproduction is financed using current energetic income during long spawning seasons in which females spawn successively over many days (Thomas 1988;Stearns 1992).…”

“…Higher winds (≥4 m/s), characteristic of thunderstorms, cold fronts, and tropical cyclones, can suspend larger particles for longer periods of time (Schoellhamer 1995;Brooks and Doyle 1998;Booth et al 2000), and cold fronts are the most frequent of such events in Mobile Bay during the fall, winter, and early spring (Miller et al 2005). In a study of Barataria Bay in 104 JACKSON AND COWAN southeastern Lousiana, Booth et al (2000) reported that between 63% and 80% of bottom sediments become resuspended during the passage of cold fronts when winds range from 4 to 10 m/s and that wind velocities ≥4 m/s occurred more than 80% of the time during the late fall, winter, and early spring. Kobashi et al (2006) reported similar results on a shoal in the shallow Gulf of Mexico and showed that sediments become resuspended within a few hours of frontal passage and settle back to the seafloor just as quickly once winds fall below 2 m/s.…”

We examined the effects of wind‐driven sediment resuspension on the stomach fullness, prey composition, and caloric intake of Bay Anchovy Anchoa mitchilli, a particulate planktivore, and age‐0 Atlantic Croaker Micropogonias undulatus, a benthic omnivore, in Mobile Bay, Alabama. Mobile Bay is a shallow estuary in the northern Gulf of Mexico with substrates ranging from silt to small sand. High‐wind events were associated with cold fronts and were characterized by wind velocities ≥4.0 m/s. Bay Anchovy stomachs were less full during such events and gut contents contained greater contributions by low‐calorie items. Atlantic Croaker stomach fullness did not differ significantly with wind speed. However, prey composition during high‐wind events shifted toward high‐calorie items. These scenarios imply that high‐wind events in Mobile Bay could have an adverse effect on energy uptake by resident Bay Anchovy but may benefit energy uptake by Atlantic Croaker.Received December 14, 2012; accepted March 23, 2013

Abstract.Observations of turbidity provide quantitative information about water quality. However, the number of available in situ measurements for water quality determination is usually limited in time and space. Here, we present an analysis of the temporal and spatial variability of the turbidity of an Amazon floodplain lake using two approaches: (1) wavelet analysis of a turbidity time series measured by an automatic monitoring system, which should be improved/simplified, and (2) turbidity samples measured in different locations and then interpolated using an ordinary Kriging algorithm. The spatial and temporal variability of turbidity are clearly related to the Amazon River flood pulses in the floodplain. When the water level in the floodplain is rising or receding, the exchange between the Amazon River and the floodplain is the major driving force in turbidity variability. At high-water levels, turbidity variability is controlled by Lake Bathymetry. When the water level is low, wind action and Lake Morphometry are the main causes of turbidity variability. The combined use of temporal and spatial data shows a good potential for better understanding of the turbidity behaviour in a complex aquatic system such as the Amazon floodplain.

Review of wave-driven sediment resuspension and transport in estuaries

Waves are fundamentally important to the physical and biological functioning of estuaries.Understanding and predicting contaminant transport, development of sedimentary structures, geomorphological response to changes in external forcings such as rising sea level, and response of estuarine ecosystems to contaminant stressors require understanding of the relative roles of wave-and current-driven sediment transport. We review wave-driven sediment resuspension and transport in estuaries, including generation of bed shear stress by waves, initiation of sediment motion by waves, and the ways waves modulate, add to, and interact with sediment transport driven by currents. A key characteristic of the waveinduced force on the seabed is extreme spatial and temporal variations; simple analytical models are revealing of the way such patterns develop. Statistical methods have been widely applied to predict wave resuspension of intertidal-flat bed sediments, and physically based predictors of resuspension developed from open-coast studies appear to also apply to short-period estuarine waves. There is ample experimental evidence to conclude that over the long term, waves erode and tidal currents accrete intertidal flats. Waves indirectly add to the formation of fluid mud by adding to the estuarine pool of fine sediment, and waves may fluidize subtidal seabeds, changing bed erodibility. Models have been used to explore the dynamic balance between sediment transport by waves and by currents and have revealed the key control of waves on estuarine morphology. Estuarine intertidal flats are excellent natural laboratories that offer opportunities for working on a number of fundamental problems in sediment transport.
