Marine geophysical measurements on the continental margins of the Labrador Sea

Canadian Journal of Earth Sciences, 1970
Seismic refraction and magnetic data from the continental margins of Labrador and south Greenland are interpreted in relation to knowledge of onshore geology.Two high-velocity seismic layers are measured on the inner part of the continental shelf off northeast Labrador. These are tentatively correlated with Precambrian crystalline rock onshore.

Evolution of nonvolcanic rifted margins: New results from the conjugate margins of the Labrador Sea

Geology, 1995
The crust across each margin of the Labrador Sea, a conjugate rift margin pair, consists of three well-defined zones: thinned continental crust, 70–80-km-wide transitional crust, and oceanic crust. The transition zone is characterized by a low-velocity upper crust (4–5 km/s) underlain by a 6.4–7.7 km/s layer.

Exploration Potential of the Deepwater Petroleum Systems of Newfoundland and Labrador Margins

Offshore Technology Conference, 2007
Abstract The deep and ultra-deep water petroleum potential of the Newfoundland and Labrador (NL) is poorly documented in the literature. Only nine wells were drilled in water deeper than 500 m and only one well has been drilled as an ultradeep, >2000 m, test.

Mass wasting along the Labrador shelf margin: Submersible observations

Geo-Marine Letters, 1987
A dissected valley system along the central portion of the Labrador upper slope has been investigated using geophysical and submersible observations. The complex slope is a result of mass wasting on a steep slope gradient which appears to be independent of processes on the bank top.

Wind Forcing of Ice Cover in the Labrador Shelf Marginal Ice Zone

Atmosphere-Ocean, 1998
Abstract Anemometer‐measured winds for the period 5–13 March 1994 were used to study the coherence of observed and forecast coastal winds along the mid‐Labrador shelf. The reliability of these variables in predicting the response of the ocean and ice to wind forcing is an important issue for ice forecasting in this area. Two anemometer‐equipped 2‐m ice

LIMEX'87: international experiment in the Labrador Sea marginal ice zone

Polar Record, 1989
ABSTRACTBetween 15 and 29 March 1987 the Labrador Ice Margin Experiment(LIMEX), a major international field experiment, took place in the Grand Banks region of the Labrador Sea, off the New found land coast. First in a series of experiments to be conducted at the southern ice margin during early spring, the period of maximum ice extent, LIMEX'87 ...

Lower Paleozoic strata in the Labrador-Baffin Seaway (Canadian margin) and Baffin Island

2022
Lower Paleozoic strata occur offshore Labrador (Middle to Upper Ordovician), offshore Baffin Island in western Davis Strait (Upper Ordovician), as well as onshore Baffin Island (Cambrian to Silurian). Paleozoic carbonate rocks (limestone and dolostone units) dominate with occurrences of siliciclastic strata found in the offshore Labrador subsurface (in

Deep seismic reflection data across the conjugate margins of the Labrador Sea

Canadian Journal of Earth Sciences, 1994
A deep seismic reflection transect of the conjugate margins of the Labrador Sea is described, which represents one of the few data sets of this kind. A characteristic reflectivity is ascribed to a 120 km wide ribbon of very thin crust that may be either thinned continental crust, which has perhaps been intruded, or oceanic crust, perhaps modified by ...

Magsat magnetic anomaly contrast across Labrador Sea passive margins

Journal of Geophysical Research: Solid Earth, 1991
Many passive margins not complicated by nearby anomalous crustal structure have satellite elevation crustal magnetic anomaly contrasts across them that are recognizable in reduced‐to‐pole versions of the Magsat and POGO data. In the Labrador Sea region this contrast is particularly well developed with strong positive anomalies overlying the continental

Marginal Basins of the Labrador Sea and the Davis Strait Hot Spot

Canadian Journal of Earth Sciences, 1975
There are deep marginal sedimentary basins in the Labrador Sea extending to the region of Davis Strait. In contrast, the central part of the Sea shoals toward Davis Strait. The difference is explained by the central part of the Sea being formed while the Davis Strait hot spot was active, producing increased vulcanism and crustal thickness.
