Cruise Inventory Information
| Long name | RRS James Clark Ross (74JC) cruise JR20040813 (JR106) |
|---|---|
| Short name | JR20040813 (JR106) |
| Objectives and Narrative | To obtain ice thickness distributions from the upward-looking swath sonar system aboard Autosub, to validate the thickness values against other data collected simultaneously from the surface and the air, and to conduct transects across and within Fram Strait so as to obtain estimates of ice flux. An important aspect of the cruise also was the development of operating methods which are suitable for ice-covered waters. |
