RRS Challenger CH117A0

Cruise summary report

Cruise Info. 
Ship name (ship code)RRS Challenger (74CH)
Cruise identifierCH117A0
Cruise period1995-01-07 — 1995-01-13
StatusCompleted
Port of departureBarry, United Kingdom
Port of returnHull, United Kingdom
PurposeResearch
ObjectivesStudying 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.
