TLDR
In this paper, it was shown that diffusion in unconsolidated sediments generally proceeds at rates ranging from half to one twentieth of those applying to diffusion of ions and molecules in free solution.About:

Diffusion of ions in sea water and in deep-sea sediments
Li Yuan-Hui,Sandra Gregory +1 more
TL;DR: The tracer diffusion coefficients of ions in deep-sea sediments, Dj,sed., can be related to Dj∗ by as mentioned in this paper, where θ is the tortuosity of the bulk sediment and a constant close to one.

Diffusion coefficients of sulfate and methane in marine sediments: Influence of porosity
TL;DR: In this article, the authors proposed a relation between D[sub 0] and [phi] using a constant (n) over a wide porosity range (0.4-0.9), with a better fit than is possible by using Archie's relation with a constant exponent.
Journal ArticleDOI
Biogeochemical cycling in an organic-rich coastal marine basin—I. Methane sediment-water exchange processes
TL;DR: In this article, the authors measured in situ with benthic chambers averages 49 and 163 μmol · m −2 · hr −1 during November-May and June-October respectively.
Journal ArticleDOI
Using models to simulate the movement of contaminants through groundwater flow systems
Mary P. Anderson,John A. Cherry +1 more
TL;DR: In this paper, a review examines the formulation of contaminant transport models, application to field problems, difficulties encountered when solving the dispersion equation, and the current lack of knowledge regarding the quantification of chemical reaction terms.
Journal ArticleDOI
Interactions of biogenic opal, sediment and seawater in the Central Equatorial Pacific
TL;DR: The solution rate of biogenic opal in near-surface sediments in the Central Equatorial Pacific is three to eight orders of magnitude lower than similar acid-cleaned samples as mentioned in this paper.

Book
Conduction of Heat in Solids
H. S. Carslaw,John Conrad Jaeger +1 more
TL;DR: In this paper, a classic account describes the known exact solutions of problems of heat flow, with detailed discussion of all the most important boundary value problems, including boundary value maximization.
Book
The mathematics of diffusion
TL;DR: Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.
Journal ArticleDOI
Migration of iron and sulfur within anaerobic sediments during early diagenesis
TL;DR: In this article, three diagenetic models based on layered situations are presented to illustrate factors affecting migration of iron and sulfur in recent anaerobic sediments, including sharp variation with depth of organic matter content and original concentration of reactive (toward H 2 S) ferruginous material.
Journal ArticleDOI
The migration of manganese in the arctic basin sediment
TL;DR: A relatively high content of manganese at the top of an arctic sediment core and a smooth exponential increment in its interstitial water down to one meter have been found.
Journal ArticleDOI
Analogy between diffusion and electrical conductivity in porous rocks
TL;DR: In this article, it was shown that the porosity of a sediment is more easily determined by electrical measurements than by diffusion measurements, and this result was confirmed by experiment and several tables of data for various rocks are presented.
