This is a complex and challenging project. Many parts of the work are at the cutting edge of science, technology or logistic capabilities. Each of these problems must be successfully overcome for complete success. The sequence of separate project elements is:

Sensors on the Grid

We’ll have at least two and maybe three new (hopefully improved) instrument packages for deployment. The purpose of more sensors is to set them in a triangular pattern so they measure the horizontal variations of water properties (temperature, current, and salinity). This will be the first opportunity to have actual measurements of these properties of a grid cell. It will only be one grid cell, but this will be a major step forward for oceanographers trying to get a handle on how the water is changing beneath the ice.
