What Lies Beneath: Blackwater and the Sargasso Sea

Dive deep into the Sargasso Sea as underwater shooters Shane Gross and Tavish Campbell capture some incredible sea creatures with blackwater photography, which is done at night in the open ocean, completely untethered. It’s not for the faint of heart.

How do you make people care about a place they’ve never heard of?

This summer I joined the Greenpeace ship Esperanza as it set sail for the Sargasso Sea, a vast ocean patch in the North Atlantic. Our mission was to show why the Sargasso Sea must be protected under the Global Oceans Treaty.

As the Visuals Lead for this leg of the Pole To Pole expedition, I brought along underwater shooters Tavish Campbell and Shane Gross to capture the splendor of this unique ecosystem.

The Sargasso Sea is teeming with wildlife, yet as I looked out at the preternaturally clear waters from the ship, I could see only an occasional seabird or flying fish. To see what else is living in this area, we would have to go much deeper.

Blackwater photography is an emerging art form in which photographers dive into the open ocean, at night, completely untethered. It’s not for the faint of heart.

Shane and Tavish dove down 100 feet over a depth of more than 13,000 feet. At each new layer of depth, they encountered incredible creatures – some larval, others fully grown. Many of these creatures migrated up from the mesopelagic-zone.

The Sargasso Sea must be protected. Click here to tell global leaders we must protect at least 30% of the oceans by 2030!
