North Carolina Department of Environment and Natural Resources Virginia Department of Conservation and Recreation Georgia Department of Natural Resources California Stormwater Quality Association ~ ii ~ Preface Disturbed soil, if not managed properly, can be washed off-site during storms. Unless proper erosion prevention and sediment control Best Management Practices (BMP’s) are used for construction activities, silt transport to a local waterbody is likely. Excessive silt causes adverse impacts due to biological alterations, reduced passage in rivers and streams, higher drinking water treatment costs for removing the sediment, and the alteration of water’s physical/chemical properties, resulting in degradation of its quality. This degradation process is known as “siltation”. Silt is one of the most frequently cited pollutants in Tennessee waterways. The division has experimented with multiple ways to determine if a stream, river, or reservoir is impaired due to silt.

Comparison of a sediment trap and plankton pump for time- series sampling of larvae near deep-sea hydrothermal vents Stace E. Beaulieu*1, Lauren S. Mullineaux1, Diane K. Adams2, Susan W. Mills1 1Biology Department, Woods Hole Oceanographic Institution, Woods Hole, MA, USA 2National Institutes of Health, National Institute of Dental and Craniofacial Research, Bethesda, MD, USA Abstract Studies of larval dispersal and supply are critical to understanding benthic population and community dynamics. A major limitation to these studies in the deep sea has been the restriction of larval sampling to infre- quent research cruises. In this study, we investigated the utility of a sediment trap for autonomous, time-series sampling of larvae near deep-sea hydrothermal vents. We conducted simultaneous deployments of a time-series sediment trap and a large-volume plankton pump in close proximity on the East Pacific Rise (2510-m depth). Grouped and species-specific downward fluxes of larvae into the sediment trap were not correlated to larval abundances in pump samples, mean horizontal flow speeds, or mean horizontal larval fluxes. The sediment trap collected a higher ratio of gastropod to polychaete larvae, a lower diversity of gastropod species, and over- or undercollected some gastropod species relative to frequencies in pump sampling. These differences between the two sampling methods indicate that larval concentrations in the plankton are not well predicted by fluxes of larvae into the sediment trap. Future studies of deep-sea larvae should choose a sampling device based on spe- cific research goals.

  • Science Focus: Dead Zones
    SCIENCE FOCUS: DEAD ZONES Creeping Dead Zones This is not the title of a sequel to a Stephen King novel. "Dead zones" in this context are areas where the bottom water (the water at the sea floor) is anoxic — meaning that it has very low (or completely zero) concentrations of dissolved oxygen. These dead zones are occurring in many areas along the coasts of major continents, and they are spreading over larger areas of the sea floor. Because very few organisms can tolerate the lack of oxygen in these areas, they can destroy the habitat in which numerous organisms make their home. The cause of anoxic bottom waters is fairly simple: the organic matter produced by phytoplankton at the surface of the ocean (in the euphotic zone) sinks to the bottom (the benthic zone), where it is subject to breakdown by the action of bacteria, a process known as bacterial respiration. The problem is, while phytoplankton use carbon dioxide and produce oxygen during photosynthesis, bacteria use oxygen and give off carbon dioxide during respiration. The oxygen used by bacteria is the oxygen dissolved in the water, and that’s the same oxygen that all of the other oxygen-respiring animals on the bottom (crabs, clams, shrimp, and a host of mud-loving creatures) and swimming in the water (zooplankton, fish) require for life to continue. The "creeping dead zones" are areas in the ocean where it appears that phytoplankton productivity has been enhanced, or natural water flow has been restricted, leading to increasing bottom water anoxia. If phytoplankton productivity is enhanced, more organic matter is produced, more organic matter sinks to the bottom and is respired by bacteria, and thus more oxygen is consumed.

  • An Assessment of the Use of Sediment Traps for Estimating Upper Ocean Particle fluxes
    Journal of Marine Research, 65, 345–416, 2007 An assessment of the use of sediment traps for estimating upper ocean particle fluxes by Ken O. Buesseler1, Avan N. Antia2, Min Chen3, Scott W. Fowler4,5, Wilford D. Gardner6, Orjan Gustafsson7, Koh Harada8, Anthony F. Michaels9, Michiel Rutgers van der Loeff10, Manmohan Sarin11, Deborah K. Steinberg,12 and Thomas Trull13 ABSTRACT This review provides an assessment of sediment trap accuracy issues by gathering data to address trap hydrodynamics, the problem of zooplankton “swimmers,” and the solubilization of material after collection. For each topic, the problem is identified, its magnitude and causes reviewed using selected examples, and an update on methods to correct for the potential bias or minimize the problem using new technologies is presented. To minimize hydrodynamic biases due to flow over the trap mouth, the use of neutrally buoyant sediment traps is encouraged. The influence of swimmers is best minimized using traps that limit zooplankton access to the sample collection chamber. New data on the impact of different swimmer removal protocols at the US time-series sites HOT and BATS are compared and shown to be important. Recent data on solubilization are compiled and assessed suggesting selective losses from sinking particles to the trap supernatant after collection, which may alter both fluxes and ratios of elements in long term and typically deeper trap deployments. Different methods are needed to assess shallow and short- term trap solubilization effects, but thus far new incubation experiments suggest these impacts to be small for most elements. A discussion of trap calibration methods reviews independent assessments of flux, including elemental budgets, particle abundance and flux modeling, and emphasizes the utility of U-Th radionuclide calibration methods.

From these fluids seafloor massive sulfides (SMS) deposits are formed which are being 19 explored as possible new mining sites for (trace) metals and rare earth elements (REE). It has been 20 suggested that during mining activities large amounts of suspended matter will appear in the water column 21 due to excavation processes, and due to discharge of mining waste from the surface vessel. Understanding 22 how natural hydrothermal plumes evolve as they spread away from their source and how they affect their 23 surrounding environment may provide some analogies for the behaviour of the dilute distal part of 24 chemically enriched mining plumes.

  • Particle Ux in the Rainbow Hydrothermal Vent
    Journalof Marine Research, 59, 633–656, 2001 Particle uxinthe Rainbow hydrothermal vent eld (Mid-AtlanticRidge): Dynamics, mineral and biological composition byAlexis Khripounoff 1,Annick Vangriesheim 1,PhilippeCrassous 1, MichelSegonzac 1,Ana Colac¸o 2,DanielDesbruye `res 1 andRoxane Barthelemy 3 ABSTRACT Inorder to provideinformation about the export and the distribution of hydrothermalparticulate materialto the surrounding deep ocean, four moorings were deployed in the vicinity of the hydrothermalRainbow vent eld(Mid-Atlantic Ridge, 36° 14 9N,2250m depth).The rstmooring wasa sedimenttrap with a currentmeter deployed at 2 mfroma chimneyof the Rainbow vent eld and1.5 m abovethe bottom(a.b.) for 16 days. It representedthe reference for the initial composition ofparticles produced by the vent. The total mean mass particle ux(6.9 g m 22 d21 )wasdistinctly higherthan the uxmeasured at the shallower hydrothermal vents on the MAR segment.This particulate uxshoweda hightemporal variation at thescale of afewdaysand was characterized by ahighconcentration of sulphur(17.2%) and copper (3.5%) and a verylow concentrationof organic carbon(0.14%). Several hundred bivalve larvae belonging to thehydrothermalmytilid Bathymodio- lusazoricus werecollected in this trap at the beginning of the experiment. The density of larvae decreasedstrongly at theend, indicating a patchinessdistribution or adiscontinuousreproduction of thisspecies. The other three moorings, including sediment traps, current-meters and thermistor chains,were deployed for 304 days at differentdistances and altitudes from the Rainbow vent eld. Themean speed of the current in the rift valley was low (6 cm s 21 )andwas oriented toward the north.The total mean particle mass uxmeasuredwith the vesedimenttraps varied little, from 10.6 to 25.0 mg m m22 d21 ,anddisplayed temporal variations which are typical of deep-sea environ- mentswith seasonal changes in the overlying production.
