The project is testing scientific and engineering work around the preservation and restoration of sea ice in the Arctic Ocean. The importance of the Arctic sea ice for global climate as well as for local populations is well documented scientifically. We want to demonstrate that sea ice can be thickened up using simple devices incorporating a submersible water pump, and only using zero-emission energy. This is our second field test, after we completed, in February 2023, a test in Nome, Alaska, using a battery powered pump. In this phase we introduce hydrogen, as energy storage and a fuel cell, to transform the hydrogen to electricity and power and electric water pump. With the use of hydrogen, we can extend the operating time of the water pump. The submersible pump will be lowered through an ice hole (drilled with an ice auger) into sea water, and will pump a large amount of water on top of existing sea ice. This sea water will quickly freeze to thicken up the existing ice layer, potentially flooding any existing snow, and increasing the conductivity between the cold air and the sea ice itself, which will support additional ice accretion over the following period. During the test we will track a number of metrics, including the extent of water displacement, the quality and conductivity of the sea-ice created, and sea-ice, snow and air temperatures. We will be requiring (exclusive, as much as possible) access to a sea-ice area of around 5 acres. 2.5 acres will be used for our experiments, and 2.5 will be used as control area for comparison purposes. Ideally we would want to continue to monitor this area for the following winter months, to see the impact of our operations. As an example, by flooding 20cm of snow with sea water at the beginning of winter, we would expect an extra 70cm of sea ice thickness to form, compared to areas where we haven't operated.
