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 criteria.</p> Bioturbation and Ecosystem Engineering largerWorkCitation project eng; USA oceans -87.894094 -87.894094 30.239478 30.239478 2025-04-21 Dauphin Island Sea Lab, Dauphin Island, AL 0 BCO-DMO catalogue of parameters from In situ sediment characteristics acquired in the shallow subtidal shore-accessible site in Bon Secour Bay, Mobile Bay, Alabama, USA between August 7-12, 2021 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 http://lod.bco-dmo.org/id/dataset-parameter/959679.rdf Name: Sampling_Date Units: unitless Description: <p>Sampling date</p> http://lod.bco-dmo.org/id/dataset-parameter/959680.rdf Name: Latitude Units: decimal degrees Description: <p>Sampling latitude</p> http://lod.bco-dmo.org/id/dataset-parameter/959681.rdf Name: Longitude Units: decimal degrees Description: <p>Sampling longitude</p> http://lod.bco-dmo.org/id/dataset-parameter/959682.rdf Name: Core Units: unitless Description: <p>sediment core out of 3 replicates</p> http://lod.bco-dmo.org/id/dataset-parameter/959683.rdf Name: Section Units: centimeter (cm) Description: <p>thickness of sediment sampled</p> http://lod.bco-dmo.org/id/dataset-parameter/959684.rdf Name: Depth Units: centimeter (cm) Description: <p>averaged depth in sediment of sample</p> http://lod.bco-dmo.org/id/dataset-parameter/959685.rdf Name: tin_ID Units: unitless Description: <p>identification number for sample tin</p> http://lod.bco-dmo.org/id/dataset-parameter/959686.rdf Name: Salinity Units: unitless Description: <p>associated salinity of overlying water</p> http://lod.bco-dmo.org/id/dataset-parameter/959687.rdf Name: tin_weight Units: gram (gr) Description: <p>weight of sample tin</p> http://lod.bco-dmo.org/id/dataset-parameter/959688.rdf Name: tin_wet Units: gram (gr) Description: <p>weight of sample tin plus wet sediment</p> http://lod.bco-dmo.org/id/dataset-parameter/959689.rdf Name: tin_dry Units: gram (gr) Description: <p>weight of sample tin plus dried sediment</p> http://lod.bco-dmo.org/id/dataset-parameter/959690.rdf Name: tin_burned Units: gram (gr) Description: <p>weight of sample tin plus burned sediment</p> http://lod.bco-dmo.org/id/dataset-parameter/959691.rdf Name: wc_percent Units: percent (%) weight Description: <p>water content as percent of wet weight</p> http://lod.bco-dmo.org/id/dataset-parameter/959692.rdf Name: porosity Units: percent (%) volume Description: <p>porosity as percent of sediment volume</p> http://lod.bco-dmo.org/id/dataset-parameter/959693.rdf Name: loi_percent Units: percent (%) weight Description: <p>loss-on-ignition, measure of organic content</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom 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 2163 https://darchive.mblwhoilibrary.org/server/api/core/bitstreams/fc17d9cd-a298-4b33-b155-29f5047a021a/content download https://doi.org/10.26008/1912/bco-dmo.940989.1 download onLine dataset &lt;p&gt;This dataset is part of a field study examining the effect of diel oxygen cycling on faunal activity, and in turn sediment oxygen demand.

Generally, core samplers consist of a core barrel (a hollow pipe or box) and a core cutter (or cutting head), located at the advancing end of the core barrel to facilitate the sampler's advancement into the sediment. Core catchers are commonly inserted into the cutting head to prevent sample loss during retrieval.
