Description:
Abstract:
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.

Purpose:
To understand the ecology of Hawaiian coral reefs in relation to other geographic areas and to monitor change at each given site.

Process_Description:
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.
