Description:
Abstract:
This dataset consists of CRAMP surveys taken in 2007 from 9 sites on Maui, 3 sites on Molokai, and 1 site on Kauai. Sites typical have two transects along different isobaths, shallow (~3m) and deep (~10m) lines. Quantitative estimates of substrate type and species were acquired. The types and coverages were derived objectively from photographic images using PhotoGrid, a software package which analyzes random points on digital still images of coral reefs and substrate. This dataset does not include the images from the transects, which have been provided to NOAA separately.
Purpose: 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.

INSTRUMENT TYPES: digital camera: Olympus 5050 zoom digital camera

Overview_Description:
Entity_and_Attribute_Overview:
Original data received as CSV (ASCII) files, which are derived from output of PhotoGrid for all surveyed lines. Select transects were received as Microsoft Excel (*.xls) files, and subsequent exports to CSV files were made.

Directory tree is as follows:

data/ 0-data/ this denotes original files/directories as received by NODC\ 1-data/ export into CSV format for files received as Excel, *.xls format. This only occurs for files in directory 0-data/07CRAMP.CSV, which are exported to CSV files under 1-data/07CRAMP.CSV

0-data/ file: MHI2007sitedates.csv comment: Survey specifics (location, dates, depths)

subdirectory: 0-data/ 07CRAMP.CSV/ Output from PhotoGrid for various Maui sites

transect file name template: Convention is yyIISSSDDm yy : last two digits of year II : island SSS : site (see STATIONS above) DDm : depth in meters TT : transect number (sometimes TT is left off if only one transect, and sometimes .SI is suffixed).

Fields in these files: Site Name - usually NA (not available) Station - usually NA Frame No - usually NA Image Date - usually NA, get survey (image) date from filename ID Name - equivalent to TaxonName in PointCount99, this is the species recorded but for some organisms if not identifiable to the species or even genus level then just to taxanomic level ID Code - usually NA

The following are PhotoGrid parameters equivalent to PointCount parameters of the same name. Point - Point number on the frame X - X coordinate on the image for each point Y - Y coordinate on the image for each point Intensity - value for the point Red - RGB value on the image Green - RGB value on the image Blue - RGB value on the image

Note, in some files, field=Species is equivalent to ID Name above.

Notes from Kuulei Rodgers concerning these parameters: "Point X and Y are the coordinates for each of the 50 points that are generated on an image. This way if you want to go back and check if it is correct or what someone called some organism it will regenerate the frame with the random points that were originally used. If for example you see Pavona maldivensis and want to see if that is correct because you don't think it is at that site and may have been interpreted, you can go back and look at point number 7 to see what is under it. The program will use the coordinates to reconstruct the original random points on that frame. Red, Green and Blue are just the exact colors as the person who first did the analysis saw it. Since you can adjust the color balance and the contrast, the program saves the adjustments so it can be revisited if need be later."

The remaining parameters can be ignored and are usually NA: Total Points,ID Date,Site ID,Site Code,Time Code,Institution,User Name,Habitat,WQS,Length,Depth

Potential frequently asked question: -The CRAMP website lists available benthic data parameters: coral and substrate cover. Can these be derived from the PhotoGrid data given? How?

Reply from Ku'ulei Rodgers: We use ACCESS, a relational database that calculates these for us but it can be done in EXCEL as well by sorting alphabetically and deriving a percent of the total for each substrate type. For example if you have 10 points that are Porites compressa and there are 20 frames with 50 points on each, this would be 10 out of 1000 points for the whole transect so 1% cover. This is then done for each substrate type. Then all the coral species percentages are added together for a total coral cover number.

-This format is slightly different from the PhotoGrid output of previous years. Any significance?

Reply from Ku'ulei Rodgers: No significance. The Maui guys have added some algal species and other substrate types because they want to know if there is any correlation with increased algae and nutrient discharge.

Note, in some files, field=Species is equivalent to ID Name above.

0-data/ 07MaMah/ Output from PhotoGrid for Mahinahina, Maui, format as described above.

0-data/ 07 KaHan PhotoGrid Data/ Output from PhotoGrid for Hanalei, Kauai format as described above.

0-data/ Molokai/ Output from PhotoGrid for sites on Molokai format as described above.

0-data/ Ahihi Kinau PhotoGrid Data/ Output from PhotoGrid for Ahihi Kinau, Maui file naming convention: c_AHIxx.CSV, xx: transect number format as described above.

1-data/ 07CRAMP.CSV/ Export to CSV from XLS files under 0-data/07CRAMP.CSV file naming convention described above file format is different, although the important field is the "Species", which is the same as used in the format of the CSV files under 07CRAMP.CSV
