|
Type | String | Type of retrieval monitoring. In most operations, selected net sections were monitored as the full complement of gear was retrieved during a single haul event on the day setting was completed. In roughly 3% of operations, exceptionally high squid catches or other adverse conditions prevented hauling of all the gear on the day it was set; in these cases some sections were left to soak longer, even while new operations were started. In these extended retrieval or "Tomi Ami" operations, hauling was spread over 1-3 days. Types of retrieval monitoring are coded as follows: 0=monitoring of gear in an ordinary single retrieval event during the day of setting A=monitoring of the portion of gear hauled during the first day of a Tome Ami operation B=monitoring of the portion of gear hauled during the second day of a Tome Ami operation C=monitoring of the portion of gear hauled during the third day of a Tome Ami operation P=monitoring of gear of unknown origin; observer unable to determine whether sections being retrieved are from ordinary or Tomi Ami operation. During some operations, the observer was unable to monitor gear retrieval due to his illness: I=observer ill; no retrieval data recorded. | |
100
|
Depth | String | Setting depth of monitored gear. In most operations, all net sections were deployed with the top of net at the sea surface. Occasionally, an operation also included some experimental sections with the top of the net at a depth of 1 m or 2m below the surface. [Surface, 1m, 2m]. | |
