Title:
Photoquadrat Images from the Hawaii Coral Reef Assessment and Monitoring Program (CRAMP): Data from 1999 - 2002 (NODC Accession 0001115)
Abstract:
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.

Why was the data set created?

To understand the ecology of Hawaiian coral reefs in relation to other 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, lavaflows), 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.

    Fixed photoquadrats allow examination of 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. The frame dimension samples 0.33 m2 of the substrate at a height of 0.5m from the bottom. Surveys are made annually at the time of video transects.
