REGION |
Code for one of the five Pacific Island regions Pacific RAMP surveys. MHI=main Hawaiian Islands, NWHI=northwestern Hawaiian Islands, PRIA=Pacific Remote Island Areas, SAMOA=American Samoa. |
ISLAND |
Island or atoll surveyed |
SITE |
The 9-character code for the site surveyed. Combines a 3-letter island code with a site number |
LATITUDE |
Site latitude in decimal degrees |
LONGITUDE |
Site longitude in decimal degrees |
REEF_ZONE |
The reef zone for the given site (forereef, backreef, lagoon, protected slope) |
DEPTH_BIN |
Classification of depth (shallow [0–6 m], mid [6–18 m], deep [18–30 m]) based on midpoint between minimum and maximum depths of replicates at this site |
SITEVISITID |
Unique numeric identifier for each site visit record. A site visit represents a single survey at a particular site |
DATE |
Date the survey was conducted |
OBS_YEAR |
Year the survey was conducted |
DIVER |
Unique numeric code for diver conducting survey |
REPLICATEID |
Unique identifier for the point count sample within a fish survey |
REP |
Letter associated to a pair of adjacent point counts (mostly one pair per survey, thus ‘A’; can also be ‘B’ in cases where a survey involved more than one SPC-pair) |
DEPTH_M |
Depth of survey area in meters |
HARD_CORAL |
Percentage of hard coral that is part of the overall benthic cover |
MA |
Percentage of macroalgae that is part of the overall benthic cover |
CCA |
Percentage of crustose coralline algae that is part of the overall benthic cover |
SAND |
Percentage of sand algae that is part of the overall benthic cover |
OTHER |
Percentage of other categories (turf algae, soft coral and cyanobacteria) that are part of the overall benthic cover |
HABITAT_CODE |
Habitat Type. AGR (aggregate reef), APR (aggregate patch reef), APS (aggregate patch reefs), MIX (mixed habitat), PAV (pavement), PPR (pavement with patch reefs), PSC (pavement with sand channels), ROB (rock boulder), RRB (reef rubble), SAG (spur and groove), SCR (scattered coral/rock), UNK (unknown) WAL (Wall). This represents the general area in which the survey is conducted, rather than the exact area of the survey cylinders. Nominally, this is based on thinking of the survey itself as being at the centre of a 50 m*50 m cell and habitat code is for the entire cell. |
CURRENT_STRENGTH |
Strength of water current as qualitatively assessed by diver (None, Slight, Moderate, High). Contains missing values prior to 2013. |
VISIBILITY_M |
Visibility measured in meters. Between 2010 and 2014, this was estimated by divers. From 2015 onwards, horizontal visibility has been measured using a Secchi disc. All estimates capped at 30 m. |
MIN_DEPTH_M |
Minimum slope depth in meters |
MAX_DEPTH_M |
Maximum slope depth in meters |
COMPLEXITY |
Visual estimate of complexity on a six point scale (1:6) from surveys in 2010 and 2011 |
SUBSTRATE_HEIGHT_0 |
Visual estimate of percentage of survey cylinder between 0 and 20 cm in relief from surveys 2012 onwards |
SUBSTRATE_HEIGHT_20 |
Visual estimate of percentage of survey cylinder between 20 and 50 cm in relief from surveys 2012 onwards |
SUBSTRATE_HEIGHT_50 |
Visual estimate of percentage of survey cylinder between 50 and 100 cm in relief from surveys 2012 onwards |
SUBSTRATE_HEIGHT_100 |
Visual estimate of percentage of survey cylinder between 100 and 150 cm in relief from surveys 2012 onwards |
SUBSTRATE_HEIGHT_150 |
Visual estimate of percentage of survey cylinder over 150 cm in relief from surveys 2012 onwards |
MAX_HEIGHT |
Highest elevation point in SPC cylinder measured in centimeters from surveys 2012 onwards |
URCHIN_DACOR |
Semi-quantitative estimate of free urchin abundance (D: Dominant [>100], A: Abundant [51–100], C: Common [21–50], O: Occasional [6–20], R: Rare [<5]) from surveys 2012 onwards |
BORING_URCHIN_DACOR |
Semi-quantitative estimate of boring urchin abundance (D: Dominant [>500], A: Abundant [251–500], C: Common [101–250], O: Occasional [26–100], R: Rare [<25]) from surveys 2012 onwards |
SPECIES |
4-letter species code for data entry |
TAXONNAME |
Scientific name at time the species was added to the database |
COMMON_FAMILY |
Common name of family |
FAMILY |
Taxonomic family classification |
CONSUMER_GROUP |
Consumer groupings used for Pacific RAMP reporting (Primary Consumer, Secondary Consumer, Planktivore, Piscivore) |
LW_A |
Parameter ‘a’ used in length-weight calculations |
LW_B |
Parameter ‘b’ used in length-weight calculations |
LMAX |
Maximum length of the fish derived largely from FishBase |
LENGTH_CONVERSION_FACTOR |
Factor to convert total length to correct form (standard length, fork length) if the length weight A and B parameters to convert length to biomass are not in total length |
COUNT |
Number of fish observed of this size and species |
SIZE_TL_CM |
Estimated total length, for fishes this is from the tip of the snout to the tip of the longer lobe of the caudal fin, reported in centimeters. Length for rays (e.g., Myliobatidae, Dasyatidae) is measured from pectoral fin tip to pectoral fin tip |
OBS_TYPE |
A single letter representation of the observation type (I: Instantaneous, N: Non-Instantaneous, F: species first entering the cylinder 5–10 min after start of survey, T: species entering cylinder 10–30 min after start of surveys, P: Present in vicinity of survey |
