Overview

Upwelling 101

Upwelling happens when winds drive water on the ocean’s surface away and colder waters from the ocean’s deep move up to take its place. This cold water is chock-full of nutrients—it’s a smorgasbord
for some of the ocean’s tiniest life forms called phytoplankton.

This video provided by the Hakai Institute explains in 50 seconds how cold, nutrient-rich waters from the deep ocean kick start food webs when they circulate to the surface.

Phytoplankton

The Ocean’s Green Machine

Microscopic phytoplankton absorb carbon dioxide through photosynthesis. The green chlorophyll in phytoplankton changes the color of the ocean surface to green. These phytoplankton blooms are visible from space!

Our Technology

How it works

The surface water is blue in the open sea because of a lack of phytoplankton due to being far and away from the coast, where natural upwelling is more present. Our wave-powered technology upwells cold nutrient-rich water from an ocean depth of 500 meters to trigger Phytoplankton Blooms. Phytoplankton absorbs carbon dioxide to live, and when ocean nutrients are abundant, plankton populations can explode into blooms so vast that they are visible from space!

In the 5 minute video below, Philip Kithil, CEO of Ocean-based Climate Solutions, provides a detailed description of our autonomous upwelling (also known as artificial upwelling) pump.

How do we confirm CO2 removed?

CLS ARGO Floats

Ocean-based Climate Solutions are partnered with the Woodhole Group, a CLS Company that provide the biogeochemical readings that measure CO2 removed among other biogeochemical data.

For every array of ten of Oxygenators deployed in the ocean, the center will have an ARGO

Argo is an international program that uses profiling floats to observe temperature, salinity, currents, and, recently, bio-optical properties in the Earth’s oceans; it has been operational since the early 2000s. The real-time data it provides is used in climate and oceanographic research.
