4 August At the Pole
We had the same mix of old and first year reported for the day before, but one very notable feature was a soft and creamy white substance that we were unable to identify scattered across the ice (pictured). Found both in ponds and on the ice surface, it occurred in clusters and had melted itself 10+cm downwards into the ice. It appeared biological in origin and had the texture of a cosmetic cream. It could sometimes contain small areas that were yellow/brown in colour.
We had a small team of citizen scientists active on the ice (pictured), collecting melt pond depth profiles for two different ice types -- the measurements will be published here in a few days.
After leaving the ice station we returned to the pole in order to circle it at a distance of 0.7NM, making a world circumnavigation in around 30-45 minutes. In this time we saw that the white substance was scattered in clusters across several miles of ice.
