Cruise summary report

Cruise Info. 
Ship name (ship code)RV Sea Vigil (74S9)
Cruise identifierSV1A
Cruise period1993-06-30 — 1993-06-30
StatusCompleted
Port of departureHull, United Kingdom
Port of returnHull, United Kingdom
PurposeResearch
Objectives1. To develop sampling and ground-truthing protocols for use on subsequent surveys in support of CASI airborne remote sensing of estuarine and coastal waters within LOIS.
2. To obtain measurements of the optical characteristics of estuarine waters that would be relevant to the interpretation of remotely sensed (aircraft) images.
3. To measure and characterise water quality parameters which influence the absorption and reflection of light.
