    A look at the impact of climate on human activity in Newfoundland and Labrador
  • Taken on the 11th March 1980 at 1136 GMT or 0806 NST (7:16 a.m. in Western Labrador).

The photograph shows the late winter pack ice off the eastern coasts of Labrador and the island of Newfoundland.

The pack ice is generated within the region as landfast ice or new growth offshore, but incorporates varying amounts of ice from Baffin Bay, Hudson Strait and the high Arctic, some of which is multi-year ice. The movement of the pack is generally southward and landward under the control of the Labrador Current and the Coriolis force. Daily (and hourly) changes in the distribution and pattern of the ice, on the other hand, result from variability in the atmospheric controls, that is, wind direction and strength.

From the 2nd to the 8th of March the prevailing wind had been between westerly and southwesterly over much of Labrador and the island. As a result, the main pack had moved off the eastern coasts by the morning of the 11th, leaving a series of large open-water leads immediately offshore. The more compact windward (western) edge of the pack contrasts markedly with the diffuse, irregular and embayed, or "loose" condition of the leeward (eastern) edge, characterised by sea leads, polynyas, ice-tongues and open-water bights.

Considerable amounts of locally generated landfast ice remain along much of the Labrador Coast, especially north of Groswater Bay where the highly indented coast and numerous offshore islands encourage its persistence. Landfast ice has largely disappeared from the island's eastern and western coasts, reflecting the mild winter of 1979/80 in Newfoundland.

An open-water zone or 'lake' is also evident immediately off the west coast of the island, which can be attributed to southeasterly winds associated with high pressure along the east coast during the 24 hours immediately prior to the time of the photograph. Such a circulation would tend to force the inshore Gulf ice to retreat northwestward and off-shore. The same phenomenon on a smaller scale can be seen at the bottom left edge of the photograph. on the western side of Grindstone Island.

Further evidence of the mild winter is the fact that Gander and Grand Lakes are already clear of ice, although Lake Melville in Labrador is still blockaded.

The photograph also shows contrasts between snow-covered open areas-such as the 'caribou barrens' of the south coast of the island, the burnt-over area northeast of Gander, the Long Range Mountains, and the Labrador Coast- and the forested areas of the island's interior.
    Like location, climate has been a decisive factor in shaping the Newfoundland and Labrador experience.
  • This ecoregion is composed of islands, exposed headlands, and protected inlets, from Napaktok Bay south to the Strait of Belle Isle.
  • A beach and embankment along the shores of Chamberlains, Conception Bay. Taken shortly before a series of storms in 1992.
    A look at erosion along Newfoundland's coasts.
  • One very important feature of Newfoundland and Labrador is that the geological boundary of North America lies offshore at the edge of the continental shelf.
  • Table of the Costs of Newfoundland and Labrador's Geological Hazards
  • Estimating the cost of geological hazards is extremely difficult.
  • The photograph shows the fine work and impressive structures that can be made from local stone.  Local siltstone and sandstone constitute the main building material. Petites granite is used on the corners and for window and door sills.
    Dimension stone includes any natural stone that has been quarried and cut or shaped to specified sizes.
  • The main stream drains WSW and is fed by small tributary streams, by downslope seepage of water in the soil (soil water) and bedrock (ground water), and by springs emerging in the stream bed (not shown). Tributaries drain from small ponds occupying bedrock hollows eroded by glacial ice, or depressions in glacial deposits. Wetland has developed in other depressions.

Other features are also the result of glacial action. The largest of the ponds (lake) has a long narrow shape and fairly regular outline typical of concentrated glacial erosion in a pre-glacial valley. Widespread erosion by the ice sheet eroded soil and weathered rock, exposing the bedrock in rock outcrops. Some of these are on the higher ground, near the divide; others may occur in the stream's course, creating falls or rapids. Glacial erosion on the divide created a depression now occupied by a lake which drains two ways - into the basin and into the adjacent catchment.LegendDivide: the boundary between one drainage basin (catchment) and the adjacent basin.Downslope seepage: downslope movement of groundwater close to, or at the surface.Fall or rapid: steepening of a steam's gradient over an outcrop of bedrock.Lake in glacial rock-basin: a natural water body occupying a rock-basin eroded by glacial ice into bedrock.Main stream: the stream into which all the surface water in the catchment eventually flows.Ponds: small water bodies.Rock outcrop: bedrock at the surface, normally the result of glacial erosion.Tributary: a stream draining into a larger stream.Wetland: bog, fen, marsh; an area of poor drainage where poorly decomposed plant material accumulates to form peat.
    A drainage basin, or catchment as it is also called, is the part of the land surface that is drained by a single river system.
  • The Eagle Plateau ecoregion comprises the Mealy Mountains and an area south of Lake Melville in southern Labrador.
