outline of oceanography
about 250 million years ago during the early triassic period, atlantic canada lied roughly in the middle of a giant continent called pangaea. this supercontinent began to fracture 220 million years ago when the earth's lithosphere was being pulled apart from extensional stress, creating a divergent plate boundary known as the fundy basin. the focus of the rifting began somewhere between where present-day eastern north america and northwestern africa were joined. during the formation of the fundy basin, volcanic activity never stopped as shown by the going eruption of lava along the mid-atlantic ridge; an underwater volcanic mountain range in the atlantic ocean formed as a result of continuous seafloor spreading between eastern north america and northwestern africa. as the fundy basin continued to form 201 million years ago, a series of basaltic lava flows were erupted, forming a volcanic mountain range on the mainland portion of southwestern nova scotia known as north mountain, stretching from brier island in the south to cape split in the north. this series of lava flows cover most of the fundy basin and extend under the bay of fundy where parts of it are exposed on the shore at the rural community of five islands, east of parrsboro on the north side of the bay. large dikes wide exist throughout southernmost new brunswick with ages and compositions similar to the north mountain basalt, indicating these dikes were the source for north mountain lava flows. however, north mountain is the remnants of a larger volcanic feature that has now been largely eroded based on the existence of basin border faults and erosion. the hard basaltic ridge of north mountain resisted the grinding of ice sheets that flowed over this region during the past ice ages, and now forms one side of the annapolis valley in the western part of the nova scotia peninsula. the layering of a north mountain lava flow less than thick at mckay head, closely resemble that of some hawaiian lava lakes, indicating hawaiian eruptions occurred during the formation of north mountain.
