Water column methane oxidation adjacent to an area of active hydrate dissociation, Eel river Basin
- D. Valentine, D. C. Blanton, W. S. Reeburgh, M. Kastner
- Chemistry
- 15 August 2001
Abstract The role of methane clathrate hydrates in the global methane budget is poorly understood because little is known about how much methane from decomposing hydrates actually reaches the… Expand
Diagenesis of siliceous oozes—I. Chemical controls on the rate of opal-A to opal-CT transformation—an experimental study
- M. Kastner, J. Keene, J. Gieskes
- Geology
- 1 August 1977
Abstract Evidence from deep-sea sediments supports the following diagenetic maturation sequence: opal-A (siliceous ooze) → opal-CT (porcelanite) → chalcedony or cryptocrystalline quartz (chert). A… Expand
Gas hydrate occurrence from pore water chlorinity and downhole logs in a transect across the northern Cascadia margin (Integrated Ocean Drilling Program Expedition 311)
- A. Malinverno, M. Kastner, M. Torres, U. G. Wortmann
- Geology
- 1 August 2008
[1] A transect of four sites drilled by Integrated Ocean Drilling Program Expedition 311 provides an ideal data set to investigate the distribution of gas hydrates across the northern Cascadia… Expand
U/Th-dating living and young fossil corals from the central tropical Pacific
- K. Cobb, C. Charles, H. Cheng, M. Kastner, R. Edwards
- Geology
- 15 May 2003
This study evaluates the accuracy of U/Th dates for young (6 a few thousand years old) reef corals, both living and fossil, and explores strategies for refining those dates. The high precision of the… Expand
Constraints on the formation of sedimentary dolomite.
- P. A. Baker, M. Kastner
- Chemistry, Medicine
- Science
- 10 July 1981
The experimental replacement of calcite and aragonite by dolomite under a variety of conditions indicates that dolomitization can take place in marine and lacustrine environments under two… Expand
Origin of marine barite deposits: Sr and S isotope characterization
- A. Paytan, Sarah Mearon, K. Cobb, M. Kastner
- Geology
- 1 August 2002
Barite can precipitate in microenvironments in the water column (marine barite), from supersaturated pore fluids at the oxic-anoxic boundary within marine sediments and where Ba-rich pore fluids are… Expand
Seawater Sulfur Isotope Fluctuations in the Cretaceous
- A. Paytan, M. Kastner, D. Campbell, M. Thiemens
- Chemistry, Medicine
- Science
- 11 June 2004
The exogenic sulfur cycle is tightly coupled with the carbon and oxygen cycles, and therefore a central component of Earth's biogeochemistry. Here we present a high-resolution record of the sulfur… Expand
ORGANIC MATTER PRESERVATION ON CONTINENTAL SLOPES: IMPORTANCE OF MINERALOGY AND SURFACE AREA
- Barbara L. Ransom, Dongseon Kim, M. Kastner, S. Wainwright
- Geology
- 1 April 1998
Theoretical considerations, calculations, and data reported by Keil et al. (1994a) were used to assess the recent hypotheses that mineral surface roughness controls the specific surface area of… Expand
Marine barite as a monitor of seawater strontium isotope composition
- A. Paytan, M. Kastner, E. Martin, J. MacDougall, T. Herbert
- Geology
- Nature
- 1 December 1993
THE strontium isotope ratio in sea water is influenced by climate, tectonics, weathering and hydrothermal activity at ocean ridges1–4. Its evolution through time, determined primarily by measuring… Expand
Benthic Ba fluxes in the central Equatorial Pacific, implications for the oceanic Ba cycle
- A. Paytan, M. Kastner
- Geology
- 1 August 1996
High resolution pore-water dissolved Ba concentration-depth profiles were determined at seven sites across an Equatorial Pacific productivity gradient from 12°S to 9°N, at 140°W. These data are… Expand
