Teacher Instructions Abstract Students will map the journey of the two masted, coastal schooner Industry 1868

In CONSTRUCT mode, drag the layers 1851_1880Hurricanes, Canada_prov, Icebergs and Icebergextent to the layer list from the All Data Files Library. In the Edit appearance window, change the colors of each layer. The Iceberg layer show the distribution of icebergs in the North Atlantic during the early 1900's. The Icebergextent layer shows the ocean area covered by continuous ice fields. Observe the relationships between all these layers by toggling the layers on and off (do this by clicking the eye symbol in the upper right side of the layer as seen in Figure 11).

Carefully examine all the layers, global winds, surface currents, 1851_1880Hurricanes, countries and ice extent in your project. Make the 1851_1880Hurricanes layer active, open the layer table, and under the field name year, select sort by ascending. Check to see if there were any major storms in December 1868 and examine the storm paths.

Your job is to estimate the route of the Industry and the Providence and the intersection of the two ships. To better inform your choice of the path of the Providence, examine the historic shipping lane maps To examine these historic shipping lane maps (.tiff format), minimize MyWorldGIS and open the David Rumsey folder located in the historical maps folder. Maximize MyWorldGIS, zoom to the Providence’s departure port of Philadelphia to identify a few common shipping routes to London. A small sample of one shipping route map is shown below in Figure 12.

After another careful reading of Sailing to Buy a Wedding Dress, highlight all the navigational clues for each vessel, one for the Industry and one for the Providence. Take notes of each journey, as you will use these notes to reconstruct the journey and draw (digitize) the path of each ship.

First make sure that your scale is in nautical miles, In the menu bar choose Edit>Preferences, and change the Measurement Units to nautical miles. In VISUALIZE mode, click the Measure Tool.

One significant navigational clue from Sailing to Buy a Wedding Dress is that the crew of the Providence found the Industry approximately 700 nautical miles from the Nova Scotia coast. Use the measure tool to estimate the maximum range of the Industry. Measure from the eastern coast of Nova Scotia approximately 700 miles out to sea. The segment length and total mileage will be visible on the bottom of the MyWorldGIS frame. Notice that you can create an arc of 700 miles, the Industry could be located anywhere along this arc. Because you are using the measure tool to “eye ball” the distances only, double click to remove your measurement line.

Now that you have carefully read Sailing to Buy a Wedding Dress again, examined all the layers, studied the David Rumsey maps, you are ready to draw the possible paths of the Industry and the Providence.

To digitize means that you create a new feature on the map. This could be a line feature, as in a road; a point feature, as in a town; or a polygon feature, as in a country. You are going to create two line features, one following the journey of the Industry and one following the Providence.

Select Edit/Preferences and check to see that you have set the projection to Lambert Conformal Conic.

Digitizing a line: For the coming instructions, you will need to zoom in and out using the Zoom-in and Zoom-out buttons to easily identify and digitize. In EDIT mode, click the button that is labeled Create a new empty layer just below the Layer list heading. In the New Layer window, choose line, and name the new layer Industry_route. Click the Create Layer button; see Figure 13 below.
