LL_STATION

Unique numerical code for each cruise. Specific to a vessel and season. Five digits, where first 2 digits indicate vessel, next 2 year, last digit season. For example 24142 = Tenacious II 2014 fall survey or 25151 = Mary Elizabeth 2015 spring survey. If last digit = 3 it is an experimental survey trip

Unique sequential order in which stations have been completed, unique to each cruise code. Failed gear deployments each receive a non-repeated consecutive number.

A predefined identifier generated during the random station assignment indicating the area where a piece of fishing gear is to be deployed. (Strata coding modified from the SVDBS definition, see SVDBS.UNION_FSCS_SVSTA.STRATUM) Code consists of 3 parts: Stratum number (2bytes) and bottom stratum type (1 bytes). Stratum number refers to strata from the SVDBS offshore stratum group with the numbers defined by depth zone. The third byte refers to the longline survey bottom strata type; 1 = smooth bottom; 0 = rough bottom. The fifth byte (following a dash as the fourth byte) is the number assigned based on the random sequential order drawn within each stratum and bottom type. For example: 270-5 would be the fifth random rough-bottom station drawn in strata 27; 361-1 would be the first random smooth-bottom station drawn in strata 36.

Unique trip identifier generated in FLDRS software. Generated to identify each fishing trip from port. Fishing operation data collected using the FLDRS software and initially loaded into FVTR tables, before being migrated to this schema. See FVTR.CRPP_VERS_TRIP

Unique identifier for each fishing effort (gear deployment) within a trip, see FVTR.CRPP_VERS_TRIP

A predefined area where the longline gear was deployed. Stratum is a two digit number referring to the stratum number from the SVDBS stratum definition, see SVDBS.UNION_FSCS_SVSTA.STRATUM. All longline strata are taken from the SVDBS offshore stratum group. May be null or differ from ASSIGNED_STRATUM, if more than 50% of the gear was deployed over the boundary into an adjoining stratum.

The predefined area where the longline gear was assigned to be deployed. Stratum is a two digit number referring to the stratum number from the SVDBS stratum definition, see SVDBS.UNION_FSCS_SVSTA.STRATUM. All longline strata are taken from the SVDBS offshore stratum group. ASSIGNED STRATUM will match the first two bytes of the STATION_ID code

A bottom type substratification specific to the longline survey. Rough bottom strata were defined as areas above the 70th percentile for Terrain Rugged Index values (Hare at al. 2012) within each stratum. Regions below the 70th percentile cut point were assigned to the smooth-bottom sub-stratum.

Standard area code used for commercial data (New England Statistical Area Code) for the position of the beginning of the tow.

Datetime (UTC) when the gear is first placed in the water at the start of the fishing effort

Datetime (UTC) when setting of the gear has stopped and the gear begins to fish

Datetime (UTC) when fishing stops and hauling the gear starts

Datetime (UTC) when the gear has been completely hauled and is back aboard the vessel

Soak or haul duration of the fishing effort (h.hh), from END_SET_TIME until BEGIN_HAUL_TIME

Latitude where the gear is first placed in the water at the start of the fishing effort (ddmm.mmmm)

Longitude where the gear is first placed in the water at the start of the fishing effort (dddmm.mmmm)

Latitude where the setting of the gear has stopped and the gear begins to fish (ddmm.mmmm)

Longitude where the setting of the gear has stopped and the gear begins to fish (dddmm.mmmm)

Latitude where fishing stops and hauling the gear starts (ddmm.mmmm)

Longitude where fishing stops and hauling the gear starts (dddmm.mmmm)

Latitude where the gear has been completely hauled and is back aboard the vessel (ddmm.mmmm)

Longitude where the gear has been completely hauled and is back aboard the vessel (dddmm.mmmm)

Survey station type. See LL_STA_EVAL_CODES for values. Value = 1 is the recommended threshold for valid standard survey sets

Source for the station assignment. See LL_STA_EVAL_CODES for values. Any value is considered acceptable for valid standard survey sets

Evaluation of the condition of the longline gear made at the end of gear hauling. Most commonly tangled sections of mainline, buoy line, and hooks. Tangles could have occurred during gear setting, hauling, or while on bottom. Captured fish could have contributed to the tangle. Tangles observed at haul back do not inherently indicate a reduced fishing capacity. See LL_STA_EVAL_CODES for values. A value < 4 is the recommended threshold for valid standard survey sets

Mainline parted during hauling, once or multiple times. In most cases this will not impact fishing capacity, unless there is a loss of some gear, but may increase haul time. See LL_STA_EVAL_CODES for values. A value < 5 is the recommended threshold for valid standard survey sets

Any interactions of the survey gear with other fishing gear or other human objects. See LL_STA_EVAL_CODES for values. A value < 4 is the recommended threshold for valid standard survey sets

Category for the gear or object with which the survey interacted. See LL_STA_EVAL_CODES for values.

Any conditions or situations related to environmental conditions or biota that might have impacted the survey gear and its capacity to fish consistently. See LL_STA_EVAL_CODES for values. A value < 4 is the recommended threshold for valid standard survey sets

Equipment, computer, or other data collection problems that might have contributed to the amount or quality of the data collected. See LL_STA_EVAL_CODES for values. A value < 4 is the recommended threshold for valid standard survey sets

Comments field for notes related to the deployment of the gear

Comments field for notes related to the hauling of the gear

Comments field for notes related to the catch

Binary indicator of whether a drop camera video was taken at the station: 1 = usable video footage obtained, 0 = no usable video footage obtained

Direction of wind during deployment of gear (degrees).

Speed of wind in knots.

Height of waves (m).

Swell height (m).

Name of vessel.
