This file contains 107,560 records.


MONTH and DAY:  Are the date on which a net was pulled and the catch processed.

POLY TIME:  Is the time a polycorder program was initiated based on the
     polycorder's internal clock.  This time does not necessarily represent the
     time the net was pulled or reset, but was included as a method of checking
     errors in keypunching.  This missing value indicator used was 9999.

STATION:  Stations numbered 4 through 29 were set in the same locations as
     similarly numbered stations during the 1985 and 1986 Endicott
     Environmental Monitoring Program.  Stations 62-67 were in the same location
     as those added for the 1986 program, while stations 70-72 were added for
     the 1987 sampling.  See Figure 2 of the 1987 Endicott Fish Distribution
     and Abundance report for station locations.

INITIALS:  This is a 3 character alphanumeric variable of the polycorder
     operator's initials.

METHOD:  Method 1 represents a sample taken after the net had fished over at
     least one night.  Method 2 represents a sample taken after the net had
     fished 2 to 6 hours.  These samples were designed to collect stomach
     samples.  Method 9 indicates the net was being set and had not been 
     fished.

EHR and EMIN:  Represent the time a net was pulled using a 24 hour military
     clock.  The missing value indicator used was 99.

QUANT CODE:  Indicates the quantitative nature of a sample.  A value of 0
     indicates it was a valid sample.  A value of 1 indicates something occurred
     which may have affected the catch.  A value of 9 indicates that the net
     was being set.

SPECIES:  Species codes are defined as:
                  -1 = No fish
                  11 = Arctic char
                  22 = Arctic cisco
                  33 = Broad whitefish
                  44 = Least cisco
                  55 = Fourhorn sculpin
                  66 = Arctic cod
                  70 = Arctic flounder
                  71 = Arctic grayling
                  72 = Big daddy sculpin
                  73 = Boreal/rainbow smelt
                  74 = Capelin
                  75 = Chinook salmon
                  76 = Humpback whitefish
                  77 = Hybrid cisco
                  78 = Ninespine stickleback
                  79 = Pacific herring
                  80 = Pink salmon
                  81 = Round whitefish
                  82 = Saffron cod
                  83 = Sandlance
                  84 = Sheefish
                  85 = Slimy sculpin
                  86 = Snailfish
                  87 = Blenny
                  88 = Eelpout
                  89 = Burbot
                  90 = Chum salmon
                  91 = Wolffish
                  92 = Greenling
                  93 = Starry flounder
                  94 = Prickleback
                  95 = Threespine stickleback
                  96 = Smooth lumpsucker
                  97 = Misc. unidentified sculpin
                  99 = Missing value:  Either a -1 or a 99 appears in species on
                       the last line of each cod end's data.

LENGTH:  Forklength of a fish in millimeters.  A length of 0 indicates that no
     length was taken.

NUMBER:  The number of fish of a given species caught; if > 1, then fish were
     not measured.

     NOTE:  Lengths were taken from Arctic cisco, least cisco, Arctic char, and
     broad whitefish only.  Fifty lengths were taken of the small fish defined
     as Arctic cisco, least cisco, and broad whitefish under 150 mm and Arctic
     char under 250 mm.  Any value for number other than zero for these four
     species represents the number of smaller fish not measured.  Lengths were
     taken for all larger fish of these species.  A fish with a length of 0 and
     a number of 0 represents a fish which escaped or which could not be
     measured. These fish may have been of any size group.

CONDITION:  The condition of captured anadromous fish upon release. 0 = not
     noted, used for nontarget species; 1 = healthy; 2 = dead; 3 = sacrificed
     for sample; 9 = value on reset lines.  Essentially all entries for species
     other than Arctic char, Arctic cisco, broad whitefish, and least cisco
     are 0.  Zero values for the four target species occurred during
     subsampling, and represent healthy fish.

SHR and SMIN:  Indicates the time the net was reset using a 24-hour military
     clock.  The reset time is entered on the last line of a cod end's data.
     The missing value indicator is 9999.  If a net was not reset, the reset
     time on the last line of data for that cod end is 9999.

There are 3 files in this series.


The file COLLAR85.DAT contains 219 records.
The file COLLAR86.DAT contains 426 records.
The file COLLAR87.DAT contains 898 records.


RECORD TYPE:  Connotes the type of record, original or with BIRD 1 and BIRD 2
     switched.  This arrangement ensures that BIRD 1 comprises a complete list
     of collar sightings regardless of the identity of the bird's mate.

BIRD 1 and BIRD 2:  Collar numbers observed.  BIRD 2 is the presumed mate of
     BIRD 1.  If the collar status of BIRD 2 is unknown, BIRD 2 is blank.  If
     BIRD 2 was collared, but the collar was not read (i.e., not legible or
     numbers not visible), the entry is 'T999'.  If BIRD 2 was not wearing a
     collar, the entry is 'NNNN'.

SEX 1 and SEX 2:  Apparent sex of BIRD 1 and BIRD 2, respectively, when known.

BROOD-REARING AREA #:  Number of brood-rearing area (BRA) in which sighting
     occurred.  BRAs are numbered as in the 1986 and 1987 Snow Goose reports,
     with the following additions:
                     0 = Howe Island
                    99 = Other area; see COMMENTS

OLD COLLARS:  Some birds had collars damaged or fall off from 1985 to 1987.  In
     such cases where this was documented and a new collar put on the bird (as
     verified by leg bands), the OLD COLLARS field contains the number of the
     lost or damaged collar corresponding to the new collar number in the BIRD 1
     field.  All three data files in this series have been updated to 1987
     collar numbers.

Data records for all caribou seen in Study Plots 1, 2, and 3.  Data from both
tower observations and road surveys are included; therefore, the records are of
two basic types.  Records 1-146 are from tower observations and records 147-274
are from road surveys.
