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.
