متن کاملShort-Term Coral Bleaching Is Not Recorded by Skeletal Boron Isotopes
Coral skeletal boron isotopes have been established as a proxy for seawater pH, yet it remains unclear if and how this proxy is affected by seawater temperature. Specifically, it has never been directly tested whether coral bleaching caused by high water temperatures influences coral boron isotopes. Here we report the results from a controlled bleaching experiment conducted on the Caribbean cor...
متن کاملVital Effects and Beyond: A Modeling Perspective on Developing Paleoceanographic Proxy Relationships in Foraminifera
This paper primarily reviews our recent work on the biology and geochemistry of foraminifera with respect to their use as paleoceanographic proxies. Our approach to proxy validation and development is described, primarily from a modeler’s point of view. The approach is based on complementary steps in understanding the inorganic chemistry, inorganic isotope fractionation, and biological controls...
متن کاملStable boron isotope fractionation between dissolved B(OH)3 and B(OH)4
The stable boron isotope ratio (B/B) in marine carbonates is used as a paleo-pH recorder and is one of the most promising paleo-carbonate chemistry proxies. Understanding the thermodynamic basis of the proxy is of fundamental importance, including knowledge on the equilibrium fractionation factor between dissolved boric acid, B(OH)3, and borate ion, B(OH)4 – ( B OH 3 B OH 4 , hereafter (B3–B4))...
متن کاملVital effects in foraminifera do not compromise the use of DB as a paleo-pH indicator: Evidence from modeling
[1] The stable boron isotope composition (dB) of fossil foraminiferal shells is used as a paleo-pH recorder and is therefore one of the most promising paleocarbonate chemistry proxies (‘‘paleoacidimetry’’). One crucial question regarding this proxy is whether foraminifera record the pH of the bulk seawater or the pH of the microenvironment (diffusive boundary layer, 500 mm), which is strongly i...
