This file consists of the following seventeen (17) 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: 29MAY06 to 11JUL07]
LOCATION $ [Three (3) categories: 'BigIsl', 'Midway', 'Oahu__']
SITE $ [Seven (7) categories: 'BIPuakoEndofRd_', 'BISpencersPk___', 'OahuKaneoheBay_' 'MWCorlPoorPR___', 'MWCorlPoorBakRf', 'MWCorlRichPR___', MWCorlRichBakRf']
OBSRVR $ [Five (5) categories: 'AMF', 'CLK', 'EED', 'JPB', 'TWA']
TRANSNMBR [Transect number = 1, 2, 3 ? n, where n = 1-12 at each site if YEAR = 2006; but where n = 1-19 if (YEAR = 2007 and SITE = 'BIPuakoEndofRd_' or SITE = 'BISpencersPk___'); but where n = 1-40 if (YEAR = 2007 and SITE = OahuKaneoheBay_'); but where n = 1-80 if (YEAR = 2007 and SITE = 'MWCorlPoorBakRf' or SITE = 'MWCorlPoorPR___' or SITE = 'MWCorlRichBakRf' or SITE = 'MWCorlRichPR___')]
QUADTYP $ [Quadrat Type: either one of two types: 'REF' (for "Reference") and 'TAR' (for "Target"); 'REF' quadrats were randomly placed to estimate benthic cover of major substratum types and rugosity of the substratum 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]
QUADNMBR [Quadrat number = 1, 2, 3 ?. n, where n = 8 to 10 if (YEAR = 2006 and QUADTYP = 'REF') but where n = 7-11 if (YEAR =2006 and QUADTYP = 'TAR'); but where n = 5 if (YEAR = 2007 and QUADTYP = 'REF'); but where n = 5 to 9 if (YEAR = 2007 and QUADTYP = 'TAR').
QUADDEP_ft [Quadrat depth in feet; range from minimum 1 foot to maximum 20 feet (6.1 m)
SUBSTRTYP $ [Benthic substratum type closest to recruit(s) present within a given 'TAR' quadrat placement; ten (10) categories as for HABTYP variable]
RUG_L1_m ["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; both RUG_L1_m and RUG_L2_m (see next) measurements made with an accuracy of 0.05 m (5 cm)]
RUG_L2_m [Same measurement as RUG_L1_m except taken perpendicular to RUG_L1_m within same quadrat placement; the maximum value observed in the 2006-07 survey series for any single rugosity measurement (either RUG_L1_m or RUG_L2_m) was 4.4 m]
SPECIES $ [Four-letter acronym based on 1st 2 letters of the genus name and 1st 2 letters of the specific epithet of each fish individual recorded; the acronyms used are identical to those used by the Coral Reef Ecosystem Division (CRED) of the NOAA Fisheries, Pacific Islands Fisheries Research Center, to code all of their central and western North Pacific reef fish records]
SIZE_TLcm [Visually estimated body length in centimeters of recruit fishes recorded as present for QUADTYP = 'TAR'; TL is the abbreviation for "Total Length", the same metric is used to represent length on the CRED Fish Surveys; range: 1 to 8 cm TL (including larger, 6-10 cm TL juveniles sometimes associated with recruits) in 2006-07]
HABTYP $ [In 2006 ten (10) substratum categories were used at both sites at LOCATION = 'BigIsl': live, massive or mounding (encrusting) Porites lobata coral (= 'PLob'); live rice coral Montipora capitata (= 'MoCap'); live Hawaiian finger coral Porites compressa (= 'PCom'); live cauliflower coral Pocillopora meandina (= 'PMed'); erect foliose algae > 1-cm tall (= 'EFA'); crustose (encrusting, 2-dimensional) coralline algae (= 'CCA'); "knobby" or otherwise 3-dimensional (e.g., branching) coralline algae (= 'KCA'); consolidated carbonate rock (dead coral limestone), not easily moveable by hand, and generally with turf algae < 1-cm tall (= 'L'); unconsolidated carbonate rock easily moveable by hand but = 1-cm particle diameter (= 'Ru'); and unconsolidated particulate carbonate < 1-cm diameter (= 'S'). Twelve (12) substratum categories were used in 2006 at both sites at Location = 'Midway'; these included all ten of the aforementioned categories used at Location = 'BigIsl' in 2006. In addition, another two (2) substratum categories, totaling twelve (12) categories, were used in 2006 at LOCATION = 'Midway': other Pocillopora spp were distinguished from Pocillopora meandrina as 'PX'; and live Montipora flabellata ('MoFlab') was distinguished from Montipora capitata ('MoCap'). In 2007 a total fourteen (14) substratum categories were used; these included eleven of the aforementioned 12 categories (HABTYP = 'KCA' was dropped and "knobby" coralline algae was pooled with crustose coralline algae as HABTYP = 'CCA'). In addition, 3 new categories are added at all sites at all locations for a total fourteen (14) categories in 2007: two other, live encrusting corals, Pavona duerdini ('PavDuer') and Pavona varians ('PavVar'), plus a new category ('Othr') comprising miscellaneous sessile (sponge, tunicate, etc) and weakly motile (echinoids, holothurians, etc) benthic invertebrates.
HABCOVR_UNITS36 [Benthic cover recorded as the number of squares occupied by a particular HABTYP within a given 1 m**2 quadrat; range 0 to 36 squares, hence sums to 36 squares within each quadrat; provides input for calculating percentage cover based on the fraction of squares occupied divided by 36; cover of each HABTYP in a given quadrat was estimated to the nearest unit if > 1 square and to 0.1 unit if = 1 square]
CLUSTRNMBR [Number of "cluster" within a particular 'TAR' quadrat placement, where a "cluster" is defined as a group of one or more individual fish recruits present within 10-cm distance of another recruit; range: CLUSTRNMBR ranges from 1 to a maximum of 3 in the 2006-07 data]
YEAR [two (2) categories for year in which data were recorded: 2006, 2007]

To provide taxonomic and functional characterizations of reef habitat that complement the recruit and predator reef fish density estimates provided by the companion databases named "RECRUIT_Reef_Fish_Belt_Transects_2006-07.xls" and "PREDATOR_Reef_Fish_Belt_Transects_2006-07.xls". These data represent the second and third surveys in a multi-year (spring-summer seasons only) project using in situ diver observations at sites of differing habitat structure, to descriptively test predictions relating to the use of specific habitats by the juveniles of various species of reef fishes in Hawaii.
The GPS positions of individual transects at Location = 'BigIsl' were not recorded by GPS; the transects at each of these two sites in 2006 and 2007 were scattered haphazardly throughout 1.0-1.5 ha areas and were centered on: LOCATION = 'BigIsl" and SITE = 'BIPuakoEndofRd_': 19.958 N lat, -155.858 W lon LOCATION = 'BigIsl' and SITE = 'BISpencersPk___': 20.021 N lat, -155.823 W lon
At Location = 'Oahu__' and Location = 'Midway', transect positions were grouped in sets of 2-4 by mooring site. The positions of the groups of transects surveyed in 2007 at Location = 'Oahu__' were: SITE = 'OahuKaneoheBay_' and Transect = 1,2,3,4 21.444 N lat, -157.797 W lon SITE = 'OahuKaneoheBay_' and Transect = 5,6: 21.441 N lat, -157.800 W lon SITE = 'OahuKaneoheBay_' and Transect = 7,8: 21.439 N lat, -157.798 W lon SITE = 'OahuKaneoheBay_' and Transect = 9,10: 21.435 N lat, -157.800 W lon SITE = 'OahuKaneoheBay_' and Transect = 11,12: 21.475 N lat, -157.824 W lon SITE = 'OahuKaneoheBay_' and Transect = 13,14: 21.478 N lat, -157.828 W lon SITE = 'OahuKaneoheBay_' and Transect = 15,16: 21.476 N lat, -157.831 W lon SITE = 'OahuKaneoheBay_' and Transect = 17,18: 21.493 N lat, -157.838 W lon SITE = 'OahuKaneoheBay_' and Transect = 19,20: 21.488 N lat, -157.834 W lon SITE = 'OahuKaneoheBay_' and Transect = 21,22: 21.471 N lat, -157.823 W lon SITE = 'OahuKaneoheBay_' and Transect = 23,24: 21.447 N lat, -157.801 W lon SITE = 'OahuKaneoheBay_' and Transect = 25,26: 21.446 N lat, -157.803 W lon SITE = 'OahuKaneoheBay_' and Transect = 27,28: 21.453 N lat, -157.802 W lon SITE = 'OahuKaneoheBay_' and Transect = 29,30,31: 21.469 N lat, -157.820 W lon SITE = 'OahuKaneoheBay_' and Transect = 32,33,34: 21.470 N lat, -157.825 W lon SITE = 'OahuKaneoheBay_' and Transect = 35,36,37: 21.445 N lat, -157.803 W lon SITE = 'OahuKaneoheBay_' and Transect = 38,39,40: 21.450 N lat, -157.810 W lon
In 2006 the positions of the transects at the two categories of back reef sites at Location = 'Midway" (Site = 'MWCorlPoorBakRf' and Site = 'MWCorlRichBakRf', each numbered consecutively from 1 to 12) were: SITE = 'MWCorlPoorBakRf' and TRANSECT = 1,2,3: 28.224 N lat, -177.419 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 4,5,6: 28.221 N lat, -177.421 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 7,8,9: 28.213 N lat, -177.422 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 10,11,12: 28.213 N lat, -177.422 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 1,2,3: 28.278 N lat, -177.365 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 4,5,6: 28.278 N lat, -177.365 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 7,8,9: 28.275 N lat, -177.355 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 10: 28.273 N lat, -177.351 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 11,12: 28.275 N lat, -177.355 W lon
In 2007 the transects at the two categories of back reef sites and two categories of patch reef sites at Midway were numbered 1-80 and were ordered without reference to site category. (The spatial positions of those numbered 1-12 at Midway in 2007 also did not necessarily coincide with the positions of those transects with the respective numbers in 2006; i.e., the transects were not fixed in position between years.) The positions of the series of 80 transects at Location = 'Midway' in 2007 were: SITE = 'MWCorlPoorPR___' and TRANSECT = 1,2,3: 28.223 N lat, -177.378 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 4,5,6: 28.226 N lat, -177.384 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 7,8,9: 28.223 N lat, -177.397 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 10,11,12: 28.220 N lat, -177.421 W lon SITE = 'MWCorlRichPR___' and TRANSECT = 13,14,15: 28.222 N lat, -177.404 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 16,17,18: 28.217 N lat, -177.409 W lon SITE = 'MWCorlRichPR___' and TRANSECT = 19,20,21: 28.237 N lat, -177.395 W lon SITE = 'MWCorlRichPR___' and TRANSECT = 22,23,24: 28.233 N lat, -177.386 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 25,26,27: 28.272 N lat, -177.348 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 28,29,30: 28.273 N lat, -177.350 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 31,32,33: 28.278 N lat, -177.367 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 34,35,36: 28.277 N lat, -177.362 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 37,38,39: 28.215 N lat, -177.422 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 40,41,42: 28.209 N lat, -177.422 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 43,44,45: 28.195 N lat, -177.407 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 46,47,48: 28.216 N lat, -177.393 W lon SITE = 'MWCorlRichPR___' and TRANSECT = 49,50,51: 28.218 N lat, -177.404 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 52,53,54: 28.217 N lat, -177.398 W lon SITE = 'MWCorlRichPR___' and TRANSECT = 55,56,57: 28.231 N lat, -177.402 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 58,59,60: 28.230 N lat, -177.394 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 61,62,63,64: 28.274 N lat, -177.354 W lon SITE = 'MWCorlRichBakRf' and TRANSECT = 65,66,67,68: 28.269 N lat, -177.386 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 69,70,71,72: 28.199 N lat, -177.414 W lon SITE = 'MWCorlPoorBakRf' and TRANSECT = 73,74,75,76: 28.204 N lat, -177.419 W lon SITE = 'MWCorlPoorPR___' and TRANSECT = 77,78,79,80: 28.223 N lat, -177.391 W lon
