New confirmed depth limit of Antarctic macroalgae: Palmaria decipiens found at 100 m depth in the Southern Ocean
Living specimens of the macroalga Palmaria decipiens were collected from 100 m depth, representing a new confirmed depth record, considerably exceeding the previous record of 42 m depth. Previous deeper collections (below conventional SCUBA depths) have relied on dredge/grab samples or drop camera s...

Living specimens of the macroalga Palmaria decipiens were collected from 100 m depth, representing a new confirmed depth record, considerably exceeding the previous record of 42 m depth.
