Harry Hess and sea-floor spreading [PDF]

, 1999
Harry Hess's hypothesis of sea-floor spreading brought together his long-standing interests in island arcs, oceanic topography, and the oceanic crust. The one unique feature of Hess's hypothesis was the origin of the oceanic crust as a hydration rind on ...

Large-scale groundwater flow and sedimentary diagenesis in continental shelves influence marine chemical budgets

Nature Communications
The major ion chemistry of the ocean has been assumed to be controlled by river input, hydrothermal circulation at mid-ocean ridges, carbonate production, and low-temperature alteration of seafloor basalt, but marine chemical budgets remain difficult to ...

Solid Earth Carbon Degassing and Sequestration Since 1 Billion Years Ago

Geochemistry, Geophysics, Geosystems
Solid Earth CO2 outgassing, driven by plate tectonic processes, is a key driver of carbon cycle models. However, the magnitudes and variations in outgassing are poorly constrained in deep‐time.

Miocene deep-water agglutinated foraminifera from the Lomonosov Ridge and the opening of the Fram Strait [PDF]

, 2009
Deep-water agglutinated Foraminifera (DWAF) were recovered from Miocene to Pliocene sediments in 103 samples from IODP Hole M0002A on the Lomonosov Ridge.
