Ice Navigation: Every Voyage is Different

It’s late in the season so Captain Duke Snider, sailing on a resupply voyage from New Zealand to Antarctica, is expecting virtually no sea, just glacial ice.Snider has been an ice navigator for decades, and he has seen the ocean change, not just here in the polar south, but in Arctic waters as well.“Variability is much greater than in the past when we could expect an ice breakup to occur within a calendar week, year after year, whether it was the Arctic or the Antarctic,” he says.
