Whales, Black bodies, the ocean, climate change, protest movements — over the past few years, they have all made their way into work by Mayfield Brooks, a choreographer, dancer and vocalist.

The latest setting for Brooks’s ever-evolving dance project is a majestic one: the Tall Ship Wavertree, the last iron-hulled, three-masted cargo ship in the world. Built in 1885 and docked at Pier 16, the Wavertree extends about the length of a football field.

This week, as part of the River to River Festival, Brooks (who uses they/them pronouns) finishes their whale journey with two works: “Whale Fall Abyss,” a dance performance on the ship, which is part of the South Street Seaport Museum; and “Whale Fall Reckoning,” a companion installation at a gallery — a former munitions room storage space — on Governors Island.

In “Abyss,” Brooks, wearing white, performs a compass dance — named for its circular choreography — on one end of the ship while Camilo Restrepo, in a long, swirling mint skirt that trails to the deck, is poised on a high platform, his torso undulating in what Brooks calls a spine dance. Under an American flag rippling in the breeze, Restrepo looks a little like the Statue of Liberty. Eventually Brooks, now in the same skirt, makes their way to him and they conjoin for an extended spine duet. Slowly they mesh into each other, one cradling the other in grief. It’s like their bodies are melting.
