Data Table

Data Attribute / Type Description
Record
Integer 		Record serial number (unique record identifier).
Flag
String 		Vessel flag, i.e., host nation (J=Japan, K=Korea, T=Taiwan).
Nationality
String 		Observer nationality (A=U.S., C=Canada, K=Korea, J=Japan, T=Taiwan).
Fishery
String 		Type of fishery (S=squid driftnet, L=large-mesh driftnet).
License
String 		Vessel license number (issued by flag nation).
Operation
String 		Operation number. Sequential operation ID, assigned daily, unique within fishing trip.
Direction
Integer 		Set direction (degrees). Units for values are degrees.
Latitude_Deg
Integer 		Latitude at beginning of set (degree component). Units for values are degrees.
Latitude_Min
Integer 		Latitude at beginning of set (minute component). Units for values are minutes.
Longitude_Deg
Integer 		Longitude at beginning of set (degree component). Units for values are degrees.
Longitude_Min
Integer 		Longitude at beginning of set (minute component). Units for values are minutes.
Hemisphere
String 		Hemisphere at beginning of set (E=eastern, W=western).
Latitude
Float 		Decimal latitude at beginning of set (degrees north of equator). Units for values are degrees. Measures are reported with a precision of 4.
Longitude
Float 		Decimal longitude at beginning of set (degrees west of prime meridian). Units for values are degrees. Measures are reported with a precision of 5.
Day
Integer 		Day at beginning of retrieval [1-31].
Month
Integer 		Month at beginning of retrieval [1-12].
Year
Integer 		Month at beginning of retrieval [1990-1991].
Date_Begin_Retrieval
Date 		Date at beginning of retrieval [d/m/yyyy].
Wind
Float 		Average of wind direction measured at beginning of set and end of retrieval (degrees). Units for values are degrees. Measures are reported with a precision of 4.
Beaufort
Float 		Average of wind force measured at beginning of set and end of retrieval (Beaufort scale). Measures are reported with a precision of 2.
Swell
Float 		Average swell height measured at beginning of set and end of retrieval (m). Units for values are meters. Measures are reported with a precision of 3.
SST
Float 		Average sea surface temperature measured at beginning and end of set and beginning and end of retrieval (degrees C). Units for values are degrees Celsius. Measures are reported with a precision of 3.
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.
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].
Species_code
String 		Numeric species code [see accompanying species table].
Common_name
String 		Common English name of species.
Scientific_name
String 		Scientific name of the species.
Taxonomic_Group
String 		Taxonomic group name (a set of species).
Taxonomic_Category
String 		Taxonomic category name (a set of groups).
Sections_All
Integer 		Total number of sections monitored.
Sections_Dropout
Integer 		Number of sections monitored for dropouts.
Mesh_All
Float 		Average mesh size of net panels in all sections monitored (mm). Units for values are millimters. Measures are reported with a precision of 4.
Mesh_Dropout
Float 		Average mesh size of net panels in sections monitored for dropouts (mm). Units for values are millimters. Measures are reported with a precision of 4.
Tans_All
Float 		Total number of standardized [50m] tans in all sections monitored. Measures are reported with a precision of 5.
Tans_Dropout
Float 		Total number of standardized[50m] tans in sections monitored for dropouts. Measures are reported with a precision of 4.
Decked_Dead_All
Integer 		Total number of animals decked [squid or fish] or released dead [mammals, birds, turtles] from all monitored sections.
Dropped_Alive_All
Integer 		Total number of animals dropping out during net retrieval [squid or fish] or released alive [mammals, birds, turtles] from all monitored sections.
Unknown_All
Integer 		Total number of animals of unknown status released [mammals, birds, turtles] from all monitored sections.
Decked_Dead_Dropout
Integer 		Total number of animals decked [squid or fish] or released dead [mammals, birds, turtles] from sections monitored for dropouts.
Dropped_Alive_Dropout
Integer 		Total number of animals dropping out during net retrieval [squid or fish] or released alive [mammals, birds, turtles] from sections monitored for dropouts.
Unknown_Dropout
Integer 		Total number of animals of unknown status released [mammals, birds, turtles] from sections monitored for dropouts.
