This file consists of the following eleven (11) variables. The permissible values of these variables, including names of categories if the variable is a classification variable are noted [in brackets]:
DATE $ DDMMMYY [range: 23MAY05 to 10JUN05]
ISLAND $ [One (1) category: 'BIG']
SITE $ [Three (3) categories: 'PUK_END', 'HOLO', 'MAHU']
OBSERVER $ [Two (2) categories: 'EED', 'TWA']
TRANSECT [Transect number = 1, 2, 3 ... n, where n = 1-10 if SITE = 'HOLO' or if SITE = 'MAHU' but where n = 1-8 if SITE = 'PUK_END']
QUADTYP $ [Quadrat Type: either one of two types: 'REF' (for "Reference") and 'TAR' (for "Target"); REF quadrats were randomly placed to estimate substratum percent cover and rugosity throughout transected areas; the placement of TAR quadrats was selective - they were centered over recruit reef fish sightings to provide estimates of substratum cover and rugosity where recruits occurred]
QUADNO [Quadrat number = 1, 2, 3 ... n, where n = 1-7 for (SITE = 'PUK_END' and TRANSECT = 1 and QUADTYP = REF or QUADTYP = TAR); n = 1-5 for (SITE = 'PUK_END' and TRANSECT = 2 and QUADTYP = 'REF'); n = 1-4 for (SITE = PUK_END' and TRANSECT = 2 and QUADTYP = 'TAR'); and n = 1-3 for all other TRANSECT-QUADTYP-QUADNO combinations]
RUG1 ["Rugosity Index" = ratio of conforming to straight line distance over substrate features within an individual 1-m**2 quadrat; typical values range from > 1.2 to < 3.0; the theoretical minimum value is 1.0.]
RUG2 [Same measurement as RUG1 except taken perpendicular to RUG1 within same quadrat placement; the maximum value observed in the 2005 survey series for any single rugosity measurement was 3.55.]
SUBSTRATE $ [Seven (7) major substratum categories were used: Live massive [highly three-dimensional] Porites lobata coral (= PL_MASS); live encrusting [mostly two-dimensional] Porites lobata coral (= PL_ENCR); live Hawaiian finger coral Porites compressa (= PC); live cauliflower coral Pocillopora meandina (= POC); all live coral taxa other than the aforementioned )= CORALSPP); carbonate rock (dead coral limestone), generally with short (< 1-cm tall) turfing algae (= TURF); and SAND (unconsolidated carbonate).
PCT_SUB [Percent cover estimated for each of the seven (7) substratum categories; sums to 100% within each quadrat]
