Cruise Inventory Information
| Long name | RRS Challenger (74CH) cruise CH117A0 |
|---|---|
| Short name | CH117A0 |
| Objectives and Narrative | Studying fluxes of materials into and out of the coastal zone of the east coast of the UK. The cruise was severly affected by mechanical problems. The ship limped from Barry to Dover for temporary repairs, did a small amount of scientific work in the Humber-Wash area before entering dry dock in Hull. The continuation of this cruise leg is designated CH117A. |
