Full moon helps paint vibrant, muddy 'brushstrokes' in Indonesian river — Earth from space
- Landsat 8 captured brushstroke-like sediment patterns at the Rokan River mouth in Sumatra.
- Patterns formed after a full Strawberry Moon increased tidal range and sediment suspension.
- The Rokan River is about 220 miles long and drains into the Strait of Malacca.
- The image captures a brackish estuary where tidal forces shape the shoreline.
- NASA Earth Observatory notes the tidal bore and sediment transport influence the visual patterns.
- Earth Observatory described the view as an abstract painting from above.
- The Strawberry Moon nickname relates to harvest season, not color.
- The tidal range is greatest when the sun and moon align, producing a spring tide.
- The image location is near Halang Island, within the Rokan estuary.
- NASA Earth Observatory cited sediment movement as key to the observed textures.
