TLDR
In this article, the authors estimate that upwelling must occur over a large fraction of the seafloor less than 65 Ma in age, if temperatures are < 20°C and seepage velocities are on the order of 10 to 100 cm/y.About:

Mid-Ocean Ridge Hydrothermal Fluxes and the Chemical Composition of the Ocean
Henry Elderfield,Adam Schultz +1 more
TL;DR: In this article, the authors presented estimates of mid-ocean ridge axial heat fluxes and total hydrothermal flux (9 ± 2 × 1012 W) using various geochemical methods.
Journal ArticleDOI
Carbon dioxide cycling and implications for climate on ancient Earth
Norman H. Sleep,Kevin Zahnle +1 more
TL;DR: In the early Earth, processes involving tectonics were more vigorous than at present, and the dynamic mantle buffer dominated over the crustal one as discussed by the authors, and the mantle cycle would have maintained atmospheric and oceanic CO2 reservoirs at levels where the climate was cold in the Archean unless another greenhouse gas was important.
Journal ArticleDOI
Seawater Strontium Isotopes, Oceanic Anoxic Events, and Seafloor Hydrothermal Activity in the Jurassic and Cretaceous
TL;DR: In this article, the authors investigated the possible causes of negative seawater strontium-isotope excursions (shifts to lower 87 Sr/86 Sr values) during the Jurassic and Cretaceous that were of relatively short duration (5-13 my) and showed a relatively quick recovery to pre-excursion 87 Sr / 86 Sr ratios.
Journal ArticleDOI
Evolution of a Habitable Planet
TL;DR: In this article, it is shown that Earth's climate has remained conducive to life for the past 3.5 billion years or more, despite a large increase in solar luminosity, probably because of previous higher concentrations of CO2 and/or CH4.
Journal ArticleDOI
The low-temperature geochemical cycle of iron: From continental fluxes to marine sediment deposition
Simon W. Poulton,Robert Raiswell +1 more
TL;DR: In this paper, a comparison of the globally-averaged compositions of riverine particulates and marine sediments reveals that the latter are depleted in FeHR, FePR and FeT but enriched in FeU.

Submarine Thermal Springs on the Galápagos Rift
John B. Corliss,Jack Dymond,Louis I. Gordon,John M. Edmond,Richard P. Von Herzen,Robert D. Ballard,Kenneth Green,David L. Williams,Arnold E. Bainbridge,Kathy Crane,Tjeerd H. van Andel +10 more
TL;DR: It is suggested that two-thirds of the heat lost from new oceanic lithosphere at the Gal�pagos Rift in the first million years may be vented from thermal springs, predominantly along the axial ridge within the rift valley.
Book
The chemistry of the atmosphere and oceans
TL;DR: Baker as mentioned in this paper introduced the field of river quality and provided a review of sediment and heat as pollutants and for the extensive topic of chemical water quality, empha sizing biodegradable wastes and the oxy gen balance in stream water.
Journal ArticleDOI
The heat flow through oceanic and continental crust and the heat loss of the Earth
TL;DR: In this paper, the authors used radiometric dates to estimate the amount of heat lost by the earth during the last orogenic event, the distribution of heat-producing elements, and erosion.
Journal ArticleDOI
Chemistry of submarine hydrothermal solutions at 21 °N, East Pacific Rise
TL;DR: The major ion data are consistent with the estimates based on extrapolation of the original measurements made on the hot springs from the Galapagos Spreading Center ( Edmond et al., 1979a).

Ridge crest hydrothermal activity and the balances of the major and minor elements in the ocean: The Galapagos data
John M. Edmond,Christopher I. Measures,Russell E. McDuff,L.H. Chan,Robert W. Collier,B. Grant,Louis I. Gordon,John B. Corliss +7 more
TL;DR: In this paper, samples collected by the deep submersible Alvin from four hot spring fields (T = 3 − 13°C) on the crest of the Galapagos spreading ridge show pronounced and varied compositional anomalies.
