Figures, plotting scripts, and data for "A fast, low-cost, and stable memory algorithm for implementing multicomponent transport in direct numerical simulations"
<p>This dataset contains the figures, as well as the necessary plotting scripts and data to reproduce them, for the article "A fast, low-cost, and stable memory algorithm for implementing multicomponent transport in direct numerical simulations" by Aaron J. Fillo, Jason Schlup, Guillaume Beardsell, Guillaume Blanquart, and Kyle E. Niemeyer (2019). In addition, the code used to generate the eigenvalues in Table 1 is included.</p> <p>The scripts were run in Matlab 2019a, though none of the versions used should be version-dependent. Furthermore, non-standard functions are included with dependencies hard-coded. We used export_fig (https://github.com/altmany/export_fig) to generate high-quality figures, and redistribute the version used here for reproducibility (export_fig was developed by Oliver J. Woodford and Yair M. Altman, and made available openly under the BSD 3-Clause License).</p> <p>The code included in this dataset is released under the BSD 3-Clause License (see LICENSE.txt for details), other than the source of export_fig, as described.

Surface Sedimentary Black Carbon Concentrations, Fluxes, and Stable and Radiocarbon Isotopes in the Equatorial Atlantic Ocean
<p><strong>Abstract</strong></p> <p>Surface sediments (0-1 cm) obtained from equatorial Atlantic Ocean isolated for black carbon using the chemothermal oxidation at 375 method. Multicores were taken during aboard the R.V. Endeavor (EN651) from February 27th 2020 through March 17th 2020 using a MC-800.</p> <p><strong>Core collection</strong></p> <p>MC-800 tubes were labeled (EN651-“Site number”-MC”coring attempt number”“letter of core”,ex: EN651-01-MC01a) and photographed before sectioning. The water on top of the core was syphoned off and a thin piece of stainless-steel sheet was slid under the foot of the tube. The foot was bent up and the stainless-steel sheet was used to transfer the core to the core extruder. Cores were sectioned at 1 cm intervals down to 10 cm, then 2 cm intervals down to 20 cm, using the piece of stainless-steel and a cake spatula to cut them. The remainder of the core was wrapped in combusted aluminum foil and placed in a zip-lock bag for storage. Sections of cores were stored in amber glass jars placed in a freezer. One core was transferred with the extruder to a PVC tube and capped for archival storage. If 5 or more cores were recovered, 0.5 cm sections would be taken down to 10 cm and the remainder of the core wrapped in foil and zip-lock bagged before being frozen. Due to a limited supply of jars, the 0.5 cm core sections were wrapped in combusted aluminum foil and placed in a ziplock bag before being stored with other samples. All cores and core sections were stored at -20 ̊C.</p> <p><strong>Analytical methods</strong><br>Surface sediment samples (0 – 1 cm) were dried at 60 ˚C until dry and passed through a 420 µm sieve before analysis. Total organic carbon samples were weighed into silver capsules (Elemental microanalysis silver capsules ultra-clean pressed 8 x 5 mm, D2030), acidified to remove inorganic carbon (2 M HCl), and folded into tin capsules (Costech tin capsules 10 x 10 mm, 041073). Black carbon was isolated using the CTO 375 method 34. 100 mg of samples where weighed out into ceramic crucibles and spread into a thin layer prevent charring. Sample were combusted at 375 ˚C for 24 hrs. under the flow of ultra high purity air (0.4 L min<sup>-1</sup>). The remaining sediment was transferred to GC vials for storage, then processed the same as the TOC samples to remove any inorganic carbon present (as detailed above).</p> <p><strong>Sampling equipment</strong></p> <p>Sediment cores were collected using an MC-800</p> <p><strong>Analytical instrumentation</strong></p> <p> An Elemental Analyzer (Costech 4010 Elemental Analyzer) was used for quantification of the BC and TOC fractions. The same elemental analyzer coupled to an Isotope Ratio Mass Spectrometer (Thermo Delta V Advantage) was used for the sample carbon isotopes. Radiocarbon isotopes were measured at the National Ocean Sciences Accelerator Mass spectrometry.</p> <p><strong>Parameter names, descriptions, units</strong></p> <p>Name, "Name of the sediment core from which the top 1 cm was sectioned"<br>Collection Date, "Date the multicore was collected, month/day/year<br>Lat, "Latitude of sampling site", decimal degrees<br>Lon, "Longitude of sampling site", decimal degrees<br>Depth, "Water depth of sample site", meters (m)<br>MAR, "Mass accumulation rate", grams per square centimeters per thousand years (g cm<sup>-2</sup> kyr<sup>-1</sup>), blank = no data<br>TOC, "Total organic carbon concentration", milligrams per gram dry weight (mg g<sup>-1</sup>)<br>TOC d13C, "Total organic carbon δ<sup>13</sup>C value", per mill (‰)<br>TOC D14C, "∆<sup>14</sup>C value of TOC calibrated for a reservoir age of 550 years", per mill (‰), blank = no data<br>BC, "Black carbon concentration", milligrams per gram dry weight (mg g<sup>-1</sup>)<br>BC sd, "Black carbon concentration standard deviation", milligrams per gram dry weight (mg g<sup>-1</sup>)<br>BC d13C, "Black carbon delta <sup>13</sup>C value", per mill (‰), NA<br>BC D14C, "∆<sup>14</sup>C value of the BC", per mill (‰), blank = no data<br>BC flux, "Flux of black carbon to sediments", milligrams per square centimeters per thousand years (mg cm<sup>2</sup> kyr<sup>-1</sup>), blank = no data<br>BC flux sd, "The standard devation of the flux of black carbon to sediments", milligrams per square centimeters per thousand years (mg cm<sup>2</sup> kyr<sup>-1</sup>), blank = no data</p>
