Bright sediment and flashy fall foliage greeted NASA’s Aqua satellite
as it crossed the Bay of Fundy on November 3, 2022. The Moderate
Resolution Imaging Spectroradiometer (MODIS) on board Aqua acquired a
stunning true-color image of the scene on that same day.

The mount of the Bay of Fundy opens off the northeast coast of the
state of Maine. It stretches 270 km (170 miles) northeast, separating
the Canadian provinces of New Brunswick and Nova Scotia. The Bay is
bordered stunning physical features, including fossil-filled rock
cliffs, green marshland, and sandstone statues that jut upward and are
topped by vegetation. Thick mudflats are common, especially in the
upper Bay, and provide a rich source of suspended sediment.

The Bay of Fundy is a rich marine ecosystem, providing a home for
species such as dolphin, porpoise, fish, seals, seabirds, and twelve
species of whales. Both deciduous and evergreen trees fill the
surrounding forests, creating a patchwork of green and glowing autumn
leaves in the fall. There’s even a massive whirlpool reliably kicked up
by tidal action off the coast of Maine.

The chocolate-colored rivers that flow into the Bay of Fundy pick up
sediment far upstream as they pass through soft, red, and easily-eroded
Triassic-era sandstone of northeastern Canada. In addition, the Bay’s
spectacular tidal action—it has the highest observed tides on
Earth—helps keep the Bay waters and incoming rivers muddy by churning
mudflats. At the head of the Bay, in the Minas Basin (lower one in this
image), the height of the tide can reach 16 meters (53 feet). By
comparison, most of the coast of the United States has a tidal range of
1-2 meters (3-6 feet).
