Title:
Hawaii Coral Reef Assessment and Monitoring Program (CRAMP): benthic data from digital still images made in 2008-2010 on Kauai, Oahu, Molokai, Maui, and Hawaii (NODC Accession 0104255)
Description:
Abstract:
This dataset consists of benthic data from the Hawaii Coral Reef Assessment and Monitoring Program (CRAMP) taken 2008-2010 from 24 sites on within 5 main Hawaiian Islands (Kauai, Oahu, Molokai, Maui, and Hawaii). Most sites consist of two transects along different isobaths, shallow (~2-4m) and deep (~7-13m) lines. A total of 67 transects were completed between May 2008 - November 2010. 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 are accessioned within NOAA/NODC separately.
Purpose:
geographic areas and to monitor change at each given site.

CRAMP experimental design allows detection of changes that can be attributed to various factors such as:

overuse (over-fishing, anchor damage, aquarium trade collection, etc.), sedimentation, nutrient loading, catastrophic natural events (storm wave impact, lava flows), coastal construction, urbanization, global warming (bleaching), introduced species, algal invasions, and fish and invertebrate diseases.

The emphasis of the program is on the major problems facing Hawaiian coral reefs as listed by managers and reef scientists during workshops and meetings held in Hawaii (1997-1998). These are:

over-fishing, sedimentation, eutrophication, and algal outbreaks.

CRAMP experimental design gives priority to areas where baseline data relevant to these issues were previously collected. Transect dimensions, number of replicates, and methods of evaluation have been selected to detect changes with statistical confidence. Standard techniques include the establishment of permanent transects to quantify fish, coral, algae, and invertebrates at study sites.

CRAMP researchers are quantifying changes that have occurred on coral reefs subjected to varying degrees of fishing pressure, sedimentation, eutrophication, and algal growth and are conducting experimental work in order to test hypotheses concerning the role of these environmental factors in the ecology of coral reefs. We are also in the process of resurveying, updating and integrating existing ecological information on an array of coral reefs that have been designated as areas of concern or, "hot spots," by managers and scientists.

METHODOLOGY 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.

Overview_Description:
Entity_and_Attribute_Overview:
FILE FORMATS: Original data received as CSV (ASCII) files, which are derived from output of PhotoGrid for all surveyed lines.

Directory tree and files are as follows: data/ 0-data/ this denotes original files/directories as received by NODC

The original data were provided on 8 CDs. A directory was made for each CD, cd01/, cd02/,....cd08/. Within each directory, organization varies. Some do not have any subdirectories, only CSV files. Some have additional subdirectories to sort by islands and sites. A summary of directories and filenames is given in file ../data/0-data/NODC archive list.csv.

FILE: NODC archive list.csv TYPE: ASCII text comma-separated version CONTENT: column 1: CD on which data are found column 2: year of survey column 3: Island column 4: Site column 5: Date of survey column 6: filename for output of PhotoGrid in CSV format column 7: depth (m) column 8: notes

FILENAME for output of PhotoGrid in CSV format: Convention is yyIISSSDDm.csv yy : last two digits of year II : island (first two letters of island name) SSS : site (see STATIONS above) DDm : depth in meters (optional) TT : transect number note: sometimes TT is left off if only one transect some files are suffixed by c_

FILE FORMAT 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 paramters: "Point X and Y are the coodinates 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 usally 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.
