Dried samples were placed in a muffle furnace at 550 °C for 4 h to combust sediment organic matter.&amp;nbsp;Porosity and organic content were calculated from the sediment mass differences before and after drying and combusting, respectively.&amp;nbsp;Combusted sediment was then placed in a 1% sodium hexametaphosphate solution for at least 3 weeks to deflocculate. After weeks of deflocculating, clumps of mud often remained intact in muddier samples, so all samples were gently rubbed with a gloved finger on a 63 μm sieve to break up mud clumps. The mud was then washed through the sieve and combined with the sand retained on the sieve. After breaking up clumps, we measured grain size distribution using a Malvern Mastersizer 3000. For each sample, 5 measurements were averaged and then analyzed using Gradistat (Kenneth Pye Associates, LTD.).&lt;/p&gt; &lt;p&gt;Bottom water salinity and temperature (° C) measured at each site and timepoint using a CTD (conductivity, temperature, depth) instrument array.&lt;/p&gt; Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-1844910 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=1844910 completed Kelly Dorgan Dauphin Island Sea Lab 251-861-2141 x7553 101 Bienville Blvd Dauphin Island AL 36528-4603 USA kdorgan@disl.org pointOfContact asNeeded Dataset Version: 1 Unknown Site Latidude Longitude WaterDepth_m Date TimeAfterSally_d Salinity Temperature_degC Replicate SedimentDepth_cm WaterContentFraction PorosityFraction OrganicContentFraction MEANGrainSize_um SORTING_um SKEWNESS_um KURTOSIS_um MEANGrainSize_phi SORTING_phi SKEWNESS_phi KURTOSIS_phi MEANGrainSizeDescription SORTINGDescription SKEWNESSDescription KURTOSISDescription MODE1_um MODE2_um MODE3_um MODE1_phi MODE2_phi MODE3_phi D10_um D50_um D90_um D10_phi D50_phi D90_phi GRAVELFraction SANDFraction MUDFraction VCOARSEGRAVELFraction COARSEGRAVELFraction MEDIUMGRAVELFraction FINEGRAVELFraction VFINEGRAVELFraction VCOARSESANDFraction COARSESANDFraction MEDIUMSANDFraction FINESANDFraction VFINESANDFraction VCOARSESILTFraction COARSESILTFraction MEDIUMSILTFraction FINESILTFraction VFINESILTFraction CLAYFraction grainsize_3500 grainsize_3080 grainsize_2710 grainsize_2390 grainsize_2100 grainsize_1850 grainsize_1630 grainsize_1430 grainsize_1260 grainsize_1110 grainsize_976 grainsize_859 grainsize_756 grainsize_666 grainsize_586 grainsize_516 grainsize_454 grainsize_400 grainsize_352 grainsize_310 grainsize_272 grainsize_240 grainsize_211 grainsize_186 grainsize_163 grainsize_144 grainsize_127 grainsize_111 grainsize_98_1 grainsize_86_4 grainsize_76 grainsize_66_9 grainsize_58_9 grainsize_51_8 grainsize_45_6 grainsize_40_1 grainsize_35_3 grainsize_31_1 grainsize_27_4 grainsize_24_1 grainsize_21_2 grainsize_18_7 grainsize_16_4 grainsize_14_5 grainsize_12_7 grainsize_11_2 grainsize_9_86 grainsize_8_68 grainsize_7_64 grainsize_6_72 grainsize_5_92 grainsize_5_21 grainsize_4_58 grainsize_4_03 grainsize_3_55 grainsize_3_12 grainsize_2_75 grainsize_2_42 grainsize_2_13 grainsize_1_88 grainsize_1_65 grainsize_1_45 grainsize_1_28 grainsize_1_13 grainsize_0_991 grainsize_0_872 grainsize_0_767 grainsize_0_675 grainsize_0_594 grainsize_0_523 grainsize_0_46 grainsize_0_405 grainsize_0_357 grainsize_0_314 grainsize_0_276 grainsize_0_243 grainsize_0_214 grainsize_0_188 grainsize_0_166 grainsize_0_146 grainsize_0_128 grainsize_0_113 grainsize_0_0995 grainsize_0_0876 grainsize_0_0771 grainsize_0_0679 grainsize_0_0597 grainsize_0_0526 grainsize_0_0463 grainsize_0_0407 grainsize_0_0358 grainsize_0_0315 grainsize_0_0278 grainsize_0_0244 grainsize_0_0215 grainsize_0_0189 grainsize_0_0167 grainsize_0_0147 grainsize_0_0129 grainsize_0_0114 grainsize_0_01 Ocean Instruments MC-400 multicorer Malvern Mastersizer 3000 theme None, User defined site latitude longitude depth date incubation time or duration salinity temperature of sample or a generic measurement (not in-situ water temp) replicate depth core sample fraction (includes size fractions) sediment grain size gravel sand size fraction Wentworth scale mud silt size fraction Wentworth scale clay size fraction Wentworth scale featureType BCO-DMO Standard Parameters CTD - fixed Multi Corer Particle Size Analyzer instrument BCO-DMO Standard Instruments otherRestrictions otherRestrictions Access Constraints: none.

CAREER: Mechanisms of bioturbation and ecosystem engineering by benthic infauna https://osprey.bco-dmo.org/project/811716 CAREER: Mechanisms of bioturbation and ecosystem engineering by benthic infauna <p><em>NSF Award Abstract:</em><br /> Marine sediments are important habitats for abundant and diverse communities of organisms that are important as food sources for higher trophic levels, including commercially important species. Through burrowing, constructing tubes, and feeding on sediments, these animals modify their physical and chemical environments to such an extent that they are considered ecosystem engineers. Bioturbation, the mixing of sediments by animals, is important in regenerating nutrients and transporting pollutants and carbon bound to mineral grains. Despite its importance, our ability to predict bioturbation rates and patterns from the community structure is poor, largely due to a lack of understanding of the mechanisms by which animals mix sediments. This project builds on earlier work showing that animals extend burrows through muddy sediments by fracture to test the hypothesis that the mechanical properties of sediments that affect burrowing mechanics also affect sediment mixing. More broadly, this project examines the relative contributions of (i) the functional roles of the organisms in the community, (ii) the mechanical properties of sediments, and (iii) factors that might increase or decrease animal activity such as temperature and food availability to bioturbation rates. Burrowing animals modify the physical properties of sediments, and this project quantifies these changes and tests the hypothesis that these changes are ecologically important and affect community succession following a disturbance. In addition to this scientific broader impact, this project involves development of instrumentation to measure sediment properties and includes a substantial education plan to introduce graduate, undergraduate, and middle school students to the important role that technology plays in marine science.</p> <p>Through burrowing and feeding activities, benthic infauna mix sediments and modify their physical environments. Bioturbation gates the burial of organic matter, enhances nutrient regeneration, and smears the paleontological and stratigraphic record. However, current understanding of the mechanisms by which infaunal activities mix sediments is insufficient to predict the impacts of changes in infaunal community structure on important sediment ecosystem functions driven by bioturbation. This project tests specific hypotheses relating infaunal communities, bioturbation, and geotechnical properties with the ultimate goal of understanding the dynamic changes and potential feedbacks between infauna and their physical environments. This project integrates field and lab experiments to assess the relative importance of infaunal community structure and activities to bioturbation rates. Additionally, this project builds on recent work showing that muddy sediments are elastic gels through which worms extend burrows by fracture to propose that geotechnical properties of sediments mediate bioturbation by governing the release of particles from the sediment matrix during burrow extension. Finite element modeling determines how the release of particles by fracture during burrowing depends on the fracture toughness (cohesion) and stiffness (compaction) of sediments and complements laboratory experiments characterizing the impact of geotechnical properties on burrowing behaviors. The proposed research also aims to determine whether impacts of infauna on geotechnical properties are ecologically important. Changes in infaunal communities and geotechnical properties following an experimental physical disturbance address the hypothesis that ecosystem engineering of bulk sediment properties facilitates succession.</p> <p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review

&lt;p&gt;Sediment cores&amp;nbsp;(9.6 cm inner diameter)&amp;nbsp;were collected with an Ocean Instruments MC-400 multicorer or via SCUBA diving&amp;nbsp;at each site and timepoint.&amp;nbsp;Grain size was measured in the top 8-12 cm of sediment. 1-2 cores were sectioned into 1 cm increments and dried at 65 °C for 48 h. Dried samples were placed in a muffle furnace at 550 °C for 4 h to combust sediment organic matter.&amp;nbsp;Porosity and organic content were calculated from the sediment mass differences before and after drying and combusting, respectively.&amp;nbsp;Combusted sediment was then placed in a 1% sodium hexametaphosphate solution for at least 3 weeks to deflocculate. After weeks of deflocculating, clumps of mud often remained intact in muddier samples, so all samples were gently rubbed with a gloved finger on a 63 μm sieve to break up mud clumps. The mud was then washed through the sieve and combined with the sand retained on the sieve. After breaking up clumps, we measured grain size distribution using a Malvern Mastersizer 3000. For each sample, 5 measurements were averaged and then analyzed using Gradistat (Kenneth Pye Associates, LTD.).&lt;/p&gt; &lt;p&gt;Bottom water salinity and temperature (° C) measured at each site and timepoint using a CTD (conductivity, temperature, depth) instrument array.&lt;/p&gt; Specified by the Principal Investigator(s) &lt;p&gt;For each sediment sample, 5 Malvern Mastersizer measurements were averaged and then analyzed using Gradistat v9.1 (Kenneth Pye Associates, LTD.).&lt;/p&gt; Specified by the Principal Investigator(s) asNeeded 7.x-1.1 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact PI Supplied Instrument Name: Instrument Name: CTD - fixed Instrument Short Name: Instrument Description: A reusable instrument that always simultaneously measures conductivity and temperature (for salinity) and pressure (for depth).
