Embroidery on silk, rayon and cotton thread, acrylic paint and heat transfers on wood.
120 years of Earth's ocean levels from tide gauge records (and 3 year average) is embroidered on 2 layers of 8" H x 34" W silk, then rolled and secured to 2 stationary dowels. The most recent few decades of data is immediately visible. Heat transfers with information about the level of Earth's oceans are applied to the painted wood.
