Fig. 4: Different types of salp faecal pellets found in the gel inserts of a drifting sediment trap at 200 m.
From: Krill and salp faecal pellets contribute equally to the carbon flux at the Antarctic Peninsula
The bottom crop picture shows a densely packed, intact salp faecal pellet (FP), likely including krill FP. The crop picture in the middle shows a more loosely packed salp FP, indicating that it was modified during sinking. The upper crop picture shows a very fragmented salp FP. The scale bar for the entire gel trap is 1 cm, the scale bar for the zoom-in crops is 1 mm. The black arrow indicates two krill FP for comparison.
