Keweenaw hot spot: Geophysical evidence for a 1.1 Ga mantle plume beneath the Midcontinent Rift System Keweenaw hot spot: Geophysical evidence for a 1.1 Ga mantle plume beneath the Midcontinent Rift System

The Proterozoic Midcontinent Rift System of North America is remarkably similar to Phanerozoic rifted continental margins and flood basalt provinces. Like the younger analogues, the volcanism within this older rift can be explained by decompression melting and rapid extrusion of igneous material during lithospheric extension above a broad, asthenospheric, thermal anomaly which we call...

Numerical simulation of tidal dispersion around a coastal headland Numerical simulation of tidal dispersion around a coastal headland

Tidal flows around headlands can exhibit strong spatial gradients in the Eulerian currents, resulting in complex Lagrangian trajectories and dispersion of the vertically integrated flow. This typically occurs when the horizontal length scale of the headland is comparable to or smaller than the tidal excursion. The effects of these headlands on dispersion are investigated using a...

Methods of measurement of exploratory well impacts, offshore Florida Methods of measurement of exploratory well impacts, offshore Florida

Six offshore oil well tests were drilled off Key West in the late 1950s and early 1960s. Two wells were drilled on coral bottom, two on carbonate sand, and two on mixed turtle grass and gorgonian/sponge hardbottom. After locating the sites with a proton magnetometer; several underwater assessment methods were used to measure the ecological impacts of drilling. Because of differing...

Recent geophysical and geological research in Antarctica related to the assessment of petroleum resources and potential environmental hazards to their development Recent geophysical and geological research in Antarctica related to the assessment of petroleum resources and potential environmental hazards to their development

During the 6-year negotiation of and adoption of the Convention on the Regulation of Antarctic Mineral Resources Activities on June 2, 1988, various countries have increased their attention to the possibility of exploitation of Antarctica's petroleum resources, which are covered by this treaty. However, there are no known petroleum resources in Antarctica, and scientific information is...

A dolomitized shelf edge hardground in the northern Gulf of Mexico - Reply A dolomitized shelf edge hardground in the northern Gulf of Mexico - Reply

We (Poppe et al., 1990) agree with Gerald Friedman that the anaerobic oxidation of methane is important to the early diagenetic cementation by carbonates, but we feel that a few points need clarification.
