Spectrophotometric Determination Of The Bicarbonate Dissociation Constant In Seawater, Katelyn M. Schockman, Robert H. Byrne
Spectrophotometric Determination Of The Bicarbonate Dissociation Constant In Seawater, Katelyn M. Schockman, Robert H. Byrne
Marine Science Faculty Publications
The aqueous carbon dioxide (CO2) system stoichiometric dissociation constants K1 and K2 express the relative concentrations of CO2, HCO3− (bicarbonate), and CO32− (carbonate) in terms of pH. These constants are critical in the study of seawater and the oceans because any mathematical expression that relates the four major CO2 system parameters (pH, here expressed on the total hydrogen ion concentration scale, pHT; total dissolved inorganic carbon, CT; total alkalinity, AT; and CO2 fugacity, fCO2) requires the use of …
Sediment Texture And Composition Of Sediment Cores Collected During R/V Weatherbird Ii Cruises In The Northern Gulf Of Mexico From 2010-11-18 To 2016-09-09, Gregg R. Brooks, Rebekka A. Larson

C-IMAGE data
Sediment texture and composition data were generated for selected core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to base of cores. Sediment texture values are expressed as % Gravel, % Sand, % Silt and % Clay as calculated by dry weight (g). % Mud can be calculated by combining % Silt and % Clay. Sediment composition is expressed as % carbonate content measured by acid leaching. This dataset supports the publication: Larson, R. A., Brooks, G. R., Schwing, P. T., Holmes, C. W., Carter, S. R., & Hollander, D. J. (2018). High-resolution investigation of …
In Situ Studies Of Limestone Dissolution In A Coastal Submarine Spring, Rachel Marie Schweers
In Situ Studies Of Limestone Dissolution In A Coastal Submarine Spring, Rachel Marie Schweers
USF Tampa Graduate Theses and Dissertations
Limestone dissolution in karst environments is likely due to geochemistry of the water, the actions of microbial communities, and the effect of water flow. We explored the rate of limestone dissolution and will examine here the microbial communities associated with the limestone. A conduit within the brackish cave, Double Keyhole Spring, on the coast of central west Florida was the site of the experiment. PVC pipes (5cm x 16cm) were filled with crushed limestone that was screened to a 1.9cm – 2.54cm size range. There were three treatments (5 replicates each): Control - sealed autoclaved controls with limestone and conduit …
