In Baltimore’s Inside Harbor, the Nationwide Aquarium has launched Harbor Wetland, a ten,000-square-foot floating wetland that mimics a Chesapeake Bay tidal marsh habitat. Positioned between Piers 3 and 4, the wetland options greater than 32,000 native shrubs and marsh grasses and is predicated upon sustainable improvements developed by the Aquarium’s conservation and exhibit fabrication groups.
Harbor Wetland is a free and accessible expertise accessible to Inside Harbor guests.

A Floating Classroom
Harbor Wetland is a practical constructed wetland, a floating classroom, and interesting public attraction, outfitted with docks and walkways, and shade cowl. Interpretive signage permits visitors to be taught concerning the wetland and its species whereas highlighting seasonal modifications and the sights and sounds of the harbor. The habitat is made up of recycled plastic matting planted with tidal wetland shrubs and grasses native to the area. The vegetation’ roots will develop down into the water, offering microhabitats for dozens of native species and drawing vitamins and contaminants from the water. The matting is coated with a UV protectant for sturdiness and glued to a system of air-regulated pontoons that enable for adjustable buoyancy of the wetland to offset weight acquire from rising biomass.
Water circulates by means of the wetland’s shallow channel by compressed air pumped into the channel utilizing strategically positioned airlifts. Compressed air is provided to ceramic airstones positioned on the backside of custom-designed six-foot-long airlift pipes. 1000’s of tiny bubbles produced by the airstones rise to the floor, transferring water by means of the wetland’s shallow channel. Bubbles additionally launch oxygen into the encircling water, benefitting aquatic species by elevating dissolved oxygen ranges and protecting water transferring all through the wetland as it might throughout tidal modifications in a pure tidal marsh.
“Pure habitat restoration is a key a part of our all-hands-on-deck technique to enhance the well being of the Chesapeake Bay.
