Using the ⁸⁷Sr/⁸⁶Sr of modern and paleoseep carbonates from northern Cascadia to link modern fluid flow to the past

Creator:

Joseph, C., Torres, M. E., Martin, R. A., Haley, B. A., Pohlman, J. W., Riedel, M., and Rose, K.

Abstract:

Most authigenic carbonates previously recovered from the Cascadia slope have Sr-⁸⁷/Sr-⁸⁶ signatures that reflect shallow precipitation in equilibrium with coeval seawater. There is also evidence for carbonate formation supported by fluids that have been modified by reactions with the incoming Juan de Fuca plate (Sr-⁸⁷/⁸⁶(Sr) = 0.7071; Teichert et al.,...

Metabolic balance of coastal Antarctic waters revealed by autonomous pCO₂ and ΔO₂/Ar measurements

Tortell, Philippe D., Asher, Elizabeth C., Ducklow, Hugh W., Goldman, Johanna A. L., Dacey, John W. H., Grzymski, Joseph J., Young, Jodi N., Kranz, Sven A., Bernard, Kim S., and Morel, François M. M.

Abstract:

We use autonomous gas measurements to examine the metabolic balance (photosynthesis minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...
