Cruise Inventory Information
| Long name | RRS Challenger (74CH) cruise CH6/83 |
|---|---|
| Short name | CH6/83 |
| Objectives and Narrative |
1. To investigate the development of the spring phytoplankton bloom and its ultimate collapse, resulting in a rapid sinking of phytodetritus to the benthos.
2. To attempt to detect and sample the sinking material. 3. To deploy two bathysnaps to record the arrival of the phytodetritus on the sea floor. 4. To obtain a time series of SMBA multiple corer samples at a number of stations before and after the arrival of the phytodetritus. 5. To obtain epibenthic sledge samples of a hexactinellid sponge community at around 1250m depth, and miscellaneous invertebrates at 1500m. 6. To obtain long photographic transects using the epibenthic sledge as a photosled, without nets. |
