“…The importance that seasonal overturn and wind resuspension have for production and development within the phytoplankton community is well recognized in lakes (Schelske et al 1995). Satellite imagery has documented regular sediment resuspension in the Great Lakes (Eadie et al 2002). The diatom community within these sediment plumes is significantly different from that in surrounding waters, probably because of benthic seeding.…”

Although phytoplankton blooms are major events in aquatic systems, the importance of benthic resting stages in seeding planktonic blooms is still unclear. Using microcosms, we tested the influence of benthic versus planktonic inocula on the development and taxonomic composition of diatom communities in a temperate fjord. Experiments in early spring 2002, fall 2002, and late spring 2003 showed that the type and quantity of inoculum influenced bloom development and composition. Species composition was vastly different when seeded by cells from the benthos. Species such as Detonula confervacea and Thalassiosira minima showed strong dependence on benthic propagules. Populations of Chaetoceros debilis and Thalassiosira nordenskioeldii were initiated by both benthic and planktonic cells, and benthic seeding was most successful when experiments were preceded by a planktonic bloom. Skeletonema costatum was abundant in all treatments but showed variations in size, depending on the type of inoculum. Species that do not have a resting stage, such as Pseudo-nitzschia spp., were present only in planktontreated microcosms. Seasonal factors were especially important in determining the successful growth of newly seeded populations. Our results indicate that benthic resting stages provide an important source for some species. Because the introduction of benthic resting stages to surface waters can greatly influence species composition of the plankton, it is important that studies of plankton blooms include life-history stages from both the sediments and the water column.

“…These few observations served as the foundation for hypotheses of plume effects and a major multidisciplinary program, Episodic Events Great Lakes Experiment (EEGLE) [Eadie et al, 2002]. Major goals of EEGLE were to describe and understand cross-isobath transport of biogeochemically important materials associated with resuspended sediments of major storm events and how these inputs affect the ecosystem [e.g., Schwab et al, 2000;Eadie et al, 2002]. We were interested in examining the EEGLE program hypotheses that resuspended sediment would diminish light available for phytoplankton growth, would increase P available to phytoplankton, and would stimulate the microbial food web through injection of P and detrital carbon into the food web [Eadie et al, 2002].…”

[1] As part of the Episodic Events Great Lakes Experiment, we sampled total suspended matter (TSM), light climate, nutrients, and plankton along cross-margin transects in southern Lake Michigan during February, March, and April 1998-2000 to capture conditions before, during, and after the occurrence of storm-driven recurrent coastal sediment plumes to define the anatomy of the resuspension events and get insights into their interactions with nutrients and plankton. Variability in timing and strength of winter storms among years led to different timing, intensity, and extent of plumes among years. TSM concentrations in the core of plumes varied between 15 and 30 mg L À1 , and photic depth was reduced to $1 to 2 m, thus potentially seriously limiting phytoplankton growth in plume areas. Total P concentration was highly correlated with TSM and river influence. Chlorophyll concentrations were lower in plume regions than in adjacent areas, in contrast to the relatively constant chlorophyll concentration across the plume predicted by a coupled hydrodynamic and nutrient-phytoplankton-zooplankton model. Contrary to expectation, protozoan microzooplankton (MZ) biomass was not more abundant in the plume than adjacent waters, but was highest in nearshore areas receiving river inflow. Storms affected horizontal distribution of zooplankton. Because of the lower concentrations of phytoplankton in the plume, the plume over the short term had a negative impact on zooplankton during this food-limiting season. Our results combined with those of other EEGLE studies lead us to conclude that storms and storm-driven plumes had a negative effect on the planktonic food web. Citation: Vanderploeg, H. A., et al.

“…Recent studies have focused the behavior and nature of storm-induced resuspension events, including the frequency of and meteorological conditions that cause storm-waves strong enough to resuspend shallow and deep sediments within the Great Lakes [9][10][11][12][13]. Even during baseflow conditions, ship traffic can have a significant disturbance on bed sediments, diminishing the quality of the overlying water column and degrading the aquatic ecosystem [7,14].…”

Combined sewer overflows (CSOs) negatively affect water quality in urban river and lake systems worldwide by contributing thermally enhanced waters, particulates, and various organic and inorganic contaminants. Cities that utilize CSOs must reassess aging sewer systems or minimize the impact overflows have on water quality. The Buffalo River, which drains into northeastern Lake Erie, receives contaminants from various chemical, metallurgical, and petroleum industries. Rainfall events initiate discharge from over 40 CSOs located along the River and Canal shoreline and are known to mobilize contaminated bed sediments. Therefore, this paper will illustrate how empirically derived visualizations can characterize the geographic extent and parameterize effluent from CSOs and storm-induced suspended sediment. We used oceanographic profilers and a three-dimensional visualization software package (EVS-Pro) to collect and analyze water quality data and to create visual models of parameter responses to rainfall events and baseflow. The visualizations (a) captured a distinct "first flush" from CSOs and the River, characterized as plumes of thermally enhanced water, high in turbidity and low in dissolved oxygen, (b) revealed a well-defined westward trend of cooling water and decreasing suspended sediment, away from the urban area, and (c) indicated suspended sediments departing the mouth of the Buffalo River settle quickly. The combination of intense field monitoring with dataloggers and visualizations revealed large-scale patterns and discriminated localized departures from these patterns, which can help predict sediment sinks and sources, map the geographic dispersion of effluent matter, and guide remediation efforts.
