  • Hello Mr. Stone, Thank you for the encouragement. Certainly it is best to share the knowledge, it is my occupation as a physical science(Earth & Space , Conceptual Physics) teacher.
    How many subscribers are there for the Gooseberry Journal ?
    Please write directly river.annie7@gmail.com
    I have no problem contributing to the blog, I just need anything submitted to have proper accreditation.
    Sincerely.
    Annie C. Cloutier

  • Great job! This is just the sort of material I'd love to see on Gooseberry Journal. I have some knowledge of the birds and history, but much less of the plants, geology, and shells. Any interest in blogging for Gooseberry Journal?

  1. 1. Major Flora and Fauna of the Intertidal Zones by Ann C. Cloutier MAT-General Science University of Massachusetts -Dartmouth Advisor Professor John Silva, Physics Department August, 17,2008 copyright
  2. 2. <ul><li>Geology, recent glacial events, and the causes and effects. </li></ul><ul><li>Major flora of the island. </li></ul><ul><li>Major marine organisms of the intertidal zone. </li></ul><ul><li>Human Impact and history. </li></ul><ul><li>Future of Gooseberry Island. </li></ul><ul><li>Question and Answer Time. </li></ul><ul><li>Ann C. Cloutier teaches Earth & Space Science, Botany, Oceans, Marshes & Ponds at Sandwich High School, Sandwich Massachusetts </li></ul><ul><li>She lives in Westport, Massachusetts . [email_address] </li></ul>
  3. 4. <ul><li>The Arctic ice began to advance southward 80,000 years ago during the Pleistocene Ice Age. </li></ul><ul><li>The formation of Gooseberry Island began over 20,000 years ago when the last glacial ice sheet covering this region melted, depositing till and vast quantities of meltwater. </li></ul><ul><li>This was called the Wisconsin Glacier Stage, part of the Laurentide Ice Sheet. </li></ul><ul><li>The maximum extent of the Wisconsin ice covered the area beyond Nantucket Island out to Georges Bank , past Long Island New York, edging along the continental shelf into the North Atlantic. </li></ul>
  4. 5. <ul><li>Glaciers have a basic method for moving the materials of Earth around. Incorporating a process that includes plucking rocks from the mountain sides and tops, grinding and fracturing the rock, sliding rock and ice materials along in a downward advancement to the lowest elevation, sea level. </li></ul><ul><li>All inorganic and organic material such as trees even wooly mammoths become absorbed into the glacier. </li></ul><ul><li>The glacier acts as a massive bulldozer, driven by gravity and the force of mass, pushing forward glacial lobes at the snout, and depositing till at terminated moraines as it slowly melts. </li></ul><ul><li>Glaciers are the largest instruments of Mass Movement. </li></ul>
  5. 6. <ul><li>Today, the continental shelf is underwater. This was not always the case. 20,000 years ago one could walk out to Georges Bank, and much of the edge of the continental shelf. </li></ul><ul><li>When the ice melted over six thousand years ago a difference of ~ 400 feet in sea level rise. </li></ul><ul><li>The extent of the Buzzards Bay ice lobe with its snout, covered the present day Gooseberry Island area and beyond. </li></ul>
  6. 7. <ul><li>Climate changes over the Recent Epoch include at least four glaciations - frozen times, and, inter-glaciations periods –melt downs caused by global warming. </li></ul><ul><li>A walrus tusk found in a surf clam sled off Nantucket Island is evidence of the marine mammals living here at the time when the Glacier covered this area. </li></ul><ul><li>The continental shorelines were re-shaped during each glaciation and inter-glaciation. Each event leaving geological and biological evidence for scientist to unravel through the study of fossils, carbon dating and drilling cores into the sedimentary beds of ocean floor. </li></ul>
  7. 8. <ul><li>Collecting rock specimens along Gooseberry Island, one can find igneous, metamorphic and sedimentary type rocks. </li></ul><ul><li>Many of the rocks and minerals are from Maine, New Hampshire and Canadian mountains. </li></ul><ul><li>A plant fossil found in the cobble is most likely from the Pennsylvanian time. </li></ul><ul><li>photographs by Stephen Mattos </li></ul>
  8. 10. <ul><li>Erratics are the scattered boulders of great size found on Gooseberry Island. Many are granite. </li></ul><ul><li>Frequently, the dimensions below ground are as large or greater than above ground. </li></ul><ul><li>Many Igneous rocks have been carried down from Maine or New Hampshire mountains. </li></ul><ul><li>Different ice lobes often over lapped in the past, the one covering the others till such as the Wisconsin Ice Sheet did thousands of years ago. </li></ul><ul><li>The mixing and overlaying of glacial till from northern Maine and as far west as Canada can be found in the region. </li></ul>
  9. 13. <ul><li>The major species are grasses, shrubs, angiosperms. </li></ul><ul><li>Seven Red Cedars none taller than ten feet. All trees were blown into a bent form away from the prevailing winds. </li></ul><ul><li>Invader species are thriving on the island. Rosa rugosa and honeysuckle are two outstanding examples. </li></ul><ul><li>No oaks, or pines were spotted on island. </li></ul>
  10. 25. <ul><li>In 1922, the good people of Westport started to reinforce the natural tombolo, a sand spit connecting the mainland to the island with a string of boulders on each side of the sand spit. Up until then, people had to wait for low tide to cross over to Gooseberry. </li></ul><ul><li>In 1940, the Military for purposes of World War II Homeland Security unlike anything we know today, cemented and added huge riprap boulders and steel to make a more permanent road way out to Gooseberry Island. </li></ul><ul><li>This action may have permanently altered the natural flow of sediments in an north-easterly direction, such as the littoral drift had done for thousands of years spreading sands from neighboring Horseneck Beach and South Beach RI. </li></ul>
  11. 30. <ul><li>What is the future of Gooseberry Island ? </li></ul><ul><li>Could tearing down the causeway stop future erosion of East Beach ? </li></ul><ul><li>Where have all the major sand dunes gone ? </li></ul><ul><li>What impact will sea level rise have on Gooseberry ? </li></ul><ul><li>What is our Justinian Right ? </li></ul>
  12. 31. <ul><li>Copyright August 17, 2008 </li></ul><ul><li>Power Point and Thesis by </li></ul><ul><li>Ann C. Cloutier </li></ul><ul><li>Photographs by </li></ul><ul><li>Ann C. Cloutier & Stephen D. Mattos </li></ul>
