A Stamukha is an iceberg that is touching the bottom.
We had to turn round from the ice by the coast last night and find somewhere safe to moor/anchor. There were strong winds so we needed to find somewhere else to sit them out, and the answer was a stamukha.
We knew it might drift, and it did, so when it had drifted into a more dangerous situation, Ben (who was on anchor watch) woke Nikolay and we’ve moved off it to go and have a look at the ice situation just up ahead again
