Wide-angle seismic transect across the Torngat Orogen, northern Labrador: Evidence for a Proterozoic crustal root
(1999-04)
A refraction/wide-angle reflection seismic transect across the Labrador peninsula covers the Core Zone of the SE Churchill Province, the Paleoproterozoic Torngat Orogen, and the Archean Nain Province including a portion ...
Variations in heat flow across the Goban Spur and Galicia Bank continental margins
(1991)
Presents the results of 44 new heat flow stations which were taken in 1984 and 1989 in profiles across the Goban Spur and Galicia Bank continental margins (NE Atlantic Ocean). Simple extensional models indicate that the ...
Last gasp of the Grenville Orogeny; thermochronology of the Grenville Front tectonic zone near Killarney, Ontario

Methyl-Chloride (Ch3cl) Production in Phytoplankton Cultures
(1995-01)
Unialgal nonaxenic cultures of seven species of phytoplankton, including both warm- and cold-water organisms, were examined under halocarbon-clean conditions for the production of CH3Cl. Incubations of all species showed ...
Production of chlorinated hydrocarbons and methyl iodide by the red microalga Porphyridium purpureum
(1999-05)
Two experiments were performed using axenic batch cultures of the red microalga Porphyridium purpureum. The cultures were grown in sealed 5-liter glass vessels under a high-purity artificial atmosphere and analyzed for the ...
The continent-ocean crustal transition across the southwest Greenland margin
(1994-05/10)
The complete crustal transition across the nonvolcanic, southwest Greenland continental margin of the Labrador Sea is examined using wide-angle and coincident vertical-incidence seismic profiles. Six ocean bottom seismometers ...
Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain from seismic refraction profiles: Ocean Drilling Program (Legs 149 and 173) transect
(1999-04)
We present a wide-angle seismic refraction study of an 80x40 km region of the southern Iberia Abyssal Plain, south of Galicia Bank. An intersecting grid of two E-W and four NS wide-angle reflection/refraction profiles is ...
Extinct spreading center in the Labrador Sea: Crustal structure from a two-dimensional seismic refraction velocity model
(1995-02/10)
The Labrador Sea contains a rare example of an abandoned mid-ocean ridge where active accretion of oceanic crust ceased due to a change in the spreading geometry of lithospheric plates. Seismic refraction data were collected ...
Crustal structure of the Labrador Sea conjugate margin and implications for the formation of nonvolcanic continental margins
(1995-12)
Wide-angle seismic studies have determined the detailed velocity structure along a 350-km-long profile across the Labrador margin. Combination of this model with a previously published cross section for the southwestern ...
