LEARNING ABOUT THE NATURAL HISTORY OF GRAND MANAN ISLAND

While the students are with us at Whale Camp, is it not just the marine life that they have the opportunity to learn about. Grand Manan Island is a very diverse island with a whole host of really interesting natural history and culture, from the tide pools that are influenced by the huge water movements in the bay to the fisheries that has shaped the culture and development of the islands peoples.
The geology of the island is also unique, with many factors acting over many years to make the island what it has become and is today. Many parts of Grand Manan's historic and geologic past are retained on the island are provide excellent examples of how the island was formed and providing a glimpse of what life used to be like here.

FISHERIES ON GRAND MANAN

Fishing on Grand Manan has long been a very important part of the islands culture and development. For over 200 years, the island has been inhabited by those who relied on the oceans around the coast and in the bay for fishing. Many on the island still rely on the traditional methods of smoking herring and gathering dulse, these economic livelihoods have defined the island community for hundreds of years.
At Whale Camp we give the students a glimpse into the islands past and how this has shaped the island to this day. There are many remnants of Grand Manan's fishing history still remaining on and around the island, in the shape of herring smokehouses, fishing weirs all along the coastline, and the many boats in the docks.

Teaching the students about life in the herring industry!!!

The old herring smokehouses only stopped operating in 1996


TIDEPOOLING

The tides of the Bay of Fundy are among the highest in the world, and flood into and out of the Bay every 6 hours, thus two tide cycles a day engulf the shoreline and rise up high on the cliffs of the island. On several of the islands great beaches, the tide rises enough that large areas of the beach are completely submerged for large parts of the day. This creates tidal zonation and thus gives rise a large variety of creatures utilising the different habitats and niches created by these tides.

GEOLOGY OF GRAND MANAN


Standing atop the Hole in the Wall. The Hole in the Wall is a unique natural sculpture, caused by the tides of the Bay of Fundy. The waters over time, have carved out the softer rocks from this outcrop of rocks, leaving a large hole in the rocks surrounded by harder rocks. At high tides, kayakers can paddle through, and at low tide the hole is accesible to hike down to. The hike out to the hole in the wall was one of the most popular hikes this summer, and the view of the hole and Whale Cove Bay provided a great place to stay for lunch.



An example of some of the geologic processes that help define Grand Manan is the columnar jointing that can be seen at various locations around the island
