Cruise Inventory Information
Long name | RRS Challenger (74CH) cruise CH108B |

Short name | CH108B |
Objectives and Narrative |
1. To measure the rates of nutrient fluxes between the sediments and the water column in a variety of sediment types in the LOIS RACS-C region.
2. To map the distributions of nutrients, salinity, turbidity and Th234 in the LOIS RACS-C region. 3. To deploy (and subsequently recover) four LOIS instrument moorings to measure salinity, fluorescence, and turbidity. |
