Directory: ../../data/species
The data were provided as MS Excel spreadsheets (*.xls). Redundant ASCII copies as Comma Separated Version (*.csv) were made. Filenames are based on sample location. Fields of each file include: Taxon, Family, Genus, Species, Biogeographic status (native, invasive, cryptogenic) , Range (locations in world where found), Intertidal only, Conservation notes. Nine stations total on Oahu.

2. Quantitative Data
Directory: ../../data/quantdata: Original data are *.xls. Copies in *.csv.
These data have been entered as separate spreadsheets by site and data collection type, i.e. "SandIslandrocks.xls" are the data collected at Sand Island by the rock-turning technique, and files suffixed with "Points" are the percent cover data collected by counting points and "perccov" are the data collected by visual estimation of percent cover. We have abbreviated all species names as the first four letters of genus and species, where IDs could be made confidently to species level (i.e., Ophierin = Ophiocoma erinaceus). Some organisms were recorded just to genera and these are noted that way in the spread sheet i.e., "Dictyota." Organisms that could not be readily identified in the field were recorded as "other crabs", etc.
Despite our best attempts, not all of the data were collected perfectly. Farrington High School students recorded percent cover as number of squares and there are some rounding errors that result in totals slightly higher or lower than 100 percent. Occasionally, rather than a total of 25 points, students from all the schools recorded 24, or had quadrats that totaled to 90 percent rather than 100, or did not record according to protocol, i.e. "sea urchin" instead of a species name. We corrected such errors where we could do so with confidence. Where we could not, if total counts were not far off, we included them as is. Where problems were too great, we omitted data. Data may also be missing from transect lines where conditions (usually rising tides) prevented collection.

Understand the biodiversity of Oahu's and Maui's intertidal zone
Assistance with species identifications was provided by: Erin Baumgartner (fish), Ross Langston (fish), Lisa Privatera (fish), Dave Spafford (algae), Dawn Adams (algae), Heather Spalding (algae), Cheryl Squair (algae), Megan Dailer (algae), Pakki Reath (polychaetes), Anuschka Faucci (vermetids and other molluscs), Regina Kawamoto (molluscs), Scott Godwin (crabs), Kim Andrews (cnidarians), Joanna Philipoff (echinoderms), Tamar Saturen (echinoderms), Chela Zabin (invertebrates).
Quantitative counts of key organisms were made at five sites on Oahu
and one site on Maui in 2005. Two Oahu sites were also surveyed in 2004.
The following techniques were used at most of the sites: point-intercept
along a transect line, point-intercept quadrats (25 points per quadrat)
and percent cover visual estimates (either by number of subsquares within
a quadrat or over the whole quadrat). Only the top organism was counted
per point and the percent cover data include only the upper level cover.
At two sites, Sand Island and Kahana Bay, species under or on the bottom
of cobbles were also enumerated. Transect lines were randomly or
haphazardly placed, but points/quadrats along the lines were regularly
spaced with the intention of capturing zonation patterns. Lines ran from
the water's edge (the 0 m mark) to the top of the littorine zone. Thus,
transect length varied with the site. Classes involved were: Mari Taira's
Marine Science class at Farrington High School (sites: Diamond Head,
Sand Island and Barber's Point); Baumgartner's Marine Science class at
Education Laboratory School (sites: Diamond Head and Kahana Bay, in 2004
and 2005); members of Brett Kewish's 7th grade Science class at Kahuku
Middle School (Kahuku Point/Turtle Bay); and members of Diane Bank's 7th
grade Science class at Kalama Intermediate School, Makawao (site:
Waipuilani Beach). Students worked in groups of 3-4 per transect line
and were generally assisted by 1 adult per line.
