Update
The little herc is descending at a Knoll complex, approx 90nm NNW of Aitutaki Island. We are heading down to ~4500m at this site, to support quantitative surveys on the distribution, diversity, and density of benthic megafauna. We will also be looking at substrate types and environmental conditions.
