Popis

Fixed photoquadrats are used to examine trends of individual organisms with regards to growth, recruitment and mortality. Five haphazardly selected photoquadrats at each depth contour were established with 4 pins at each corner to ensure accurate repositioning of the frame. This dataset consists of these photoquadrat images from CRAMP surveys taken from 1999 to 2002 at 27 sites within the main Hawaiian Islands. Some locations have multiple depths. Surveys were taken once per year. Field work coincided with video transects. The photoquadrat images are used to estimate change in coral coverage for the select quadrats and serve as a comparison with the video transect images and products.
