Even so, the ocean is a dynamic, challenging landscape to work in. Scientists are still uncovering new details about how it absorbs and recycles carbon, and any materials they add to seawater are liable to sink, become diluted or wash away to other locations, challenging efforts to track how the ocean responds.“It’s so hard to get the ocean to do what you want it to,” said Sarah Cooley, a carbon cycle scientist who has worked for the nonprofit Ocean Conservancy and the federal government.Katja Fennel, chair of the oceanography department at Dalhousie University, works on modeling how much carbon Planetary has captured in Halifax Harbour— a number that comes with some uncertainty.

She co-leads a group of academics that monitors the company’s project using water samples, sensors and sediment cores taken from locations around the bay. Some days, her team adds a red dye to the pipes to watch how the minerals dissolve and flow out to sea.Pink dye is released into Halifax Harbour in Nova Scotia, Canada, Thursday, Aug. 10, 2023.

The models are necessary to simulate what would happen if Planetary did nothing, Fennel said. They’re also necessary because the ocean is so large and deep it’s impossible to collect enough data to give a complete picture of it.Above ground graves are placed next to each other under the shade of a banyan tree at the Lincoln Memorial Park Cemetery, Monday, Feb. 26, 2024, in the Brownsville neighborhood of Miami.
