Hawaii Coral Reef Assessment and Monitoring Program (CRAMP): Digital Still Images from Transects on Maui, Molokai, and Kauai, 2007 (NODC Accession 0056791)
https://www.ncei.noaa.gov/archive/accession/0056791
This dataset consists of digital still transect images (JPG files) from
CRAMP surveys taken in 2007 from 9 sites on Maui, 3 sites on Molokai, and
1 site on Kauai. Sites typically have two transects along different
isobaths, shallow (~3m) and deep (~10m) lines. Digital images are
important for future researchers to resolve any question about how
the image data were interpreted for the quantitative database, to
provide the opportunity to re-analyze the images using other methods,
and to return to the same locations for future comparisons.
In a separate NODC Accession, 0051060, text data files are given of the
substrate types and coverages as derived objectively from photographic
images using PhotoGrid, a software package which analyzes random points
on images of coral reefs and substrate.
To understand the ecology of Hawaiian coral reefs in relation to other geographic areas and to monitor
change at each given site.

The 2007 surveys were 100% complete
Since the initial methods comparison in 1998, CRAMP has improved its
methodology to keep up with advances in technology, replacing video with
digital stills. Unlike prior digital cameras, recent cameras have resolution
superior to video and the card media can store close to 1,000 high quality
images. The initial costs of the equipment are lower and the images can be
archived. The valuable in situ time is shorter as well as the time spent
processing the images. Frame-grabbing is completely eliminated. The video
camera cannot keep an exact distance from the bottom while the still camera
mounted on a simple monopod assures a constant distance. With a still camera,
there are no oblique angles that can affect results since the camera is held
completely vertical by the monopod. It is however important to use consistent
methodology when comparing sites spatially and/or temporally. Yet as newer and
better technology is introduced it is important to update and upgrade methods.
CRAMP began by using video techniques and replaced this with digital stills in
2003.
Prior to the switch, the compatibility of the methods was assessed through
intercalibration, using both methods (video and digital still images) at a
large number of sites (30) that encompassed a wide range of coral cover. Once
the methods proved compatible, all subsequent surveys were conducted with
digital cameras. Non-overlapping digital stills are taken to assess the
characteristics of benthic populations. High resolution digital images are
taken along a 10 m transect using an Olympus 5050 zoom digital camera with an
Olympus PT050 underwater housing. The camera is mounted to an aluminum monopod
frame, 1.7 m from the substrate to provide a 50x69 cm image. A 6 cm bar
provides a measurement scale. The software program PhotoGrid (Bird 2001) is
used to quantify percent cover, richness and diversity of corals, algal
functional groups and substrate cover. Images are downloaded and the 20
non-overlapping images from each 10 m transect are imported into PhotoGrid
where 50 randomly selected points are projected onto each image for a total of
1,000 points per transect.
