Description:
Abstract:
Rapid Assessment Transects were conducted in 2007 in the Papahanaumokuakea Marine National Monument of the Northwest Hawaiian Islands Coral Reef Ecosystem Reserve. The surveys were led by Dr. Paul Jokiel and Mr. Erik Franklin along various depth contours at 7 unique atolls or islands. The data are quantitative estimates of substrate type and species provided in spreadsheet format (comma-separated version, CSV, text files). The types and coverages were derived objectively from photographic images using PhotoGrid, a software package which analyzes random points on images of coral reefs and substrate. This dataset does not include the images from the transects, which have been provided to NOAA separately.
Purpose:
The surveys provide an important assessment of the status of the coral ecosystem. For CRAMP purposes, the surveys expand the spatial range of habitats and add to the extensive database for the main Hawaiian Islands. These will augment the CRAMP Ecological Gradient Model to compare sites throughout the archipelago and to assess the condition of the sites.

Process_Description:
Non-overlapping digital stills are taken to assess the characteristics of benthic populations via rapid assessment transects (RATs), which are an abbreviated version of the CRAMP long-term monitoring sites. RATs have one-10 m transect instead of 10-10 m transects for the long-term monitoring sites for benthic cover. 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

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

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

0-data/ NWHI07 PhotoGrid Data/ Output from Photogrid

transect file name template: Convention is c_SSSss Transect.CSV c_: fixed, same for every file SSS: first three letters of island/atoll ss: numbered survey at each island/atoll

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.

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