<p>A global compilation of sediment surface mixed layer parameters from marine environments, compiled from published literature. The database contains parameters of advective (sedimentation rate) and diffusive (biodiffusion, bioturbation depth) particle movement estimated from tracer experiments, combined into box models.<br>Database associated with the data report published under <a href="https://doi.org/10.3389/feart.2022.1013174">https://doi.org/10.3389/feart.2022.1013174</a></p>
Core log descriptions and sediment grain size data for Hurricane Ian sediment cores collected in Lee County, Florida, USA
<p>These data represent qualitative and quantitative measurements of sediment cores collected from various environments following the landfall of Hurricane Ian. These sediment cores were collected using pound coring techniques up to 2m into the subsurface to characterize the sedimentological signature of storm deposits resulting from Hurricane Ian. More details regarding these measurements and interpretations of storm deposits can be found in the folllowing manuscript:</p> <p>McCormick, W.M., Briggs, T.R., Hauptman, L.H., Wang, P., Morphologic and sedimentological signatures resulting from Hurricane Ian, southwest Florida, USA: Insight into intra-storm bidirectional sediment transport processes (In Review). </p>

Higher temperatures exacerbate effects of antibiotics on methanogenesis in freshwater sediment
<p>This dataset features data and code of the associated publication in Communications Earth & Environment (<a href="https://doi.org/10.1038/s43247-024-01828-3" target="_blank" rel="noopener">https://doi.org/10.1038/s43247-024-01828-3</a>). To reproducibly run the code you should download the entire <code>.zip</code> archive and open the <code>*.RProj</code> file ideally with the same R version (<code>4.3.1</code>). To achieve maximum reproducibility of the code you should run <code>renv::restore()</code> to restore the packages recorded in <code>renv.lock</code>. Scripts within the folder <code>code</code> are named in the order in which they should be run. Note that running the Bayesian models requires a C++ toolchain. A web search of "RStan Getting Started" will yield up to date information about how to install this on your device. The models ran for the publication are provided as <code>.rds</code> file in case you don't want to run it yourself. Some figures required post-export editing in the paid program "Affinity photo". The edited and unedited versions are included in this repository to allow for comparisons. Also the <code>.afphoto</code> files are included for users that own a license.</p>
Investigating sediment supply impact on centennial saltmarsh biogeomorphic development with Demeter
<p>This repository contains a series of simulations to investigate the impact of (changing) sediment supply on the long-term biogeomorphic development (200 years) of saltmarshes (4 km<sup>2</sup>). The model used is Demeter (https://doi.org/10.5281/zenodo.7101535). </p> <p>Each simulation output file contains:</p> <ul> <li>yearly bottom elevation maps (resolution of 5 m);</li> <li>yearly vegetation coverage maps (resolution of 5 m);</li> <li>yearly hydroperiod maps (resolution of 5 m);</li> <li>yearly exceeding bottom shear impulse maps (resolution of 5 m);</li> <li>vegetation distribution maps every 5 years (resolution of 50 cm).</li> </ul> <p>Each simulation is also processed to compute channel network characteristics with TidalGeoPro (https://doi.org/10.5281/zenodo.7153257), such as:</p> <ul> <li>maximum upstream channel length along channel network skeleton every 20 years (resolution of 5 m);</li> <li>total upstream channel length within tidal watershed along channel network skeleton every 20 years (resolution of 5 m);</li> <li>tidal watershed surface area along channel network skeleton every 20 years (resolution of 5 m);</li> <li>mean unchanneled path length within tidal watershed along channel network skeleton every 20 years (resolution of 5 m);</li> <li>channel cross-section width, depth and area along channel network skeleton every 20 years (resolution of 5 m);</li> <li>yearly unchanneled path length maps (resolution of 5 m).</li> </ul> <p>If you are interested to use this dataset, or collaborate with the authors, please contact Olivier Gourgue (ogourgue@gmail.com).</p>
