BODC Cruise Metadata Report for RRS Challenger (74CH) cruise CH117A0

Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

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.
