EPS 146/247: Ocean Ridges and the Earth System

Class

Course will present our current knowledge of the ocean ridge system where two thirds of Earth's crust is continually being created. We will examine the progressive understanding of ocean ridges from a historical perspective, emphasizing the process of...

Global correlations of ocean ridge basalt chemistry with axial depth and crustal thickness

Journal Article

Regional averages of the major element chemistry of ocean ridge basalts, corrected for low-pressure fractionation, correlate with regional averages of axial depth for the global system of ocean ridges, including hot spots, cold spots, and back arc basins...

Vanadium isotope compositions of mid-ocean ridge lavas and altered oceanic crust

Journal Article

Vanadium isotope compositions of igneous rocks have the potential to constrain variations of physico-chemical conditions such as oxidation states during magmatism. Here, we present V isotope data for 27 fresh lavas (ranging from basaltic to dacitic...

Carbon Fluxes and Primary Magma CO2 Contents Along the Global Mid‐Ocean Ridge System

Journal Article

The concentration of carbon in primary mid‐ocean ridge basalts (MORBs), and the associated fluxes of CO₂ outgassed at ocean ridges, is examined through new data obtained by secondary ion mass spectrometry (SIMS) on 753 globally distributed MORB glasses...

Delayed CO2 emissions from mid-ocean ridge volcanism as a possible cause of late-Pleistocene glacial cycles

Journal Article

The coupled 100,000 year variations in ice volume, temperature, and atmospheric CO2 during the late Pleistocene are generally considered to arise from a combination of orbital forcing, ice dynamics, and ocean circulation. Also previously argued is that...

Petrological Systematics of Mid-Ocean Ridge Basalts : Constraints on Melt Generation Beneath Ocean Ridges

Conference Paper

Ocean ridges spring surprises

Journal Article

The meaning of “mean F”: Clarifying the mean extent of melting at ocean ridges

Journal Article

In a recent paper, Forsyth (1993) concludes that fractional melting leads to unexpected relationships between the degree of melting (F), crustal thickness, and the depth of melting beneath mid-ocean ridges. Specifically, he suggests that a commonly cited...

Volcano Ocean Ice Climate Experiments (VOICE)

Page

The long term control of Earth's climate is related to volcanoes, which emit carbon dioxide to the atmosphere. Volcanism itself is also influenced by climate through ice age cycles. A thick layer of ice enclosing a volcano on land inhibits eruption. When...

Teaching

Page

Teaching includes a general course for undergradutes that is accessible both to beginning Earth scientists and the non-science major, a course in my specialty of igneous petrolgy, and a newly developed inter-disciplinary course on ocean ridges and the...
