Final answer:
Navigation Charts from the Marshall Islands, also known as stick charts, were created using wood from coconut fronds and fibers from coconut husks. They represented wave patterns and were used for oceanic navigation.
Step-by-step explanation:
2: Wood and fiber. The Navigation Charts from the Marshall Islands were traditionally made using materials commonly found in the islands' environment. The Marshallese navigators crafted these charts, known as stick charts, from the midribs of coconut fronds, which served as the framework. They then tied these together using fibers made from coconut husks to represent the wave patterns between islands. These stick charts did not include the exact locations of the islands but rather were a conceptual representation of the swell patterns and currents which the navigators would memorize before a voyage.
The Navigation Chart, also known as the "Stick Chart," from the Marshall Islands in the 19th to early 20th century CE was created using wood and fiber as the main materials.
The framework of the chart was made from wood, usually from the midribs of coconut palm fronds. These were carved and tied together to form a grid-like structure.
The actual paths and wave patterns on the chart were represented by fiber or string, which were woven and attached to the wooden framework to mimic the ocean currents, swells, and wave patterns in the specific region being represented.
