The Role of Appendicularians in Southern Ocean Carbon Flow and Trophodynamics
Data acquisition:\n Samples were collected using a 1.5 metre diameter Ring net (150 micron metre mesh) with a wide cod-end on the base (volume approximately 40 Litres). Vertical trawls were to 20 m (unless otherwise specified). Deployment speed was determined by wave conditions with hauling speed at...
