AGRRA Database and Summary Products
The AGRRA Access database contains information for the 2480 site surveys that were completed from 1997 to the present. Hundreds of individuals from many nations in the tropical Western Atlantic have participated in this international collaboration; we are grateful for all their contributions.
New data that is collected goes through a vetting process before becoming part of the official AGRRA database. This new data is kept “on hold” to allow the contributing researcher time to complete analyses and publications. During this time, the data is not available to the public. When new data becomes part of the public database, an updated release will be made available on this website with an announcement being made as part of our regularly released newsletter.
Public Release Database includes (as of March 2018):
- 786 sites
- 4,568 benthic transects
- 1,638 coral transects
- 60,184 coral heads surveyed
- 7,638 fish transects
- 309,574 fish surveyed
Full AGRRA Database includes (as of March 2018):
- 2,480 sites
- 6,288 benthic transects
- 12,009 coral transects
- 177,008 coral heads surveyed
- 22,294 fish transects
- 757,553 fish surveyed
In addition to the AGRRA database in Microsoft Access format, Excel spreadsheets containing summary products derived from these data are also provided.
Before using the database or summary products, users are urged to consult the README file.
As you use these data, please take careful note of all survey dates. Remember that the AGRRA data are only representative of the dates of their collection, and the condition of some of the surveyed reef areas may have changed.
GIS shapefiles allow the AGRRA databases to be accessed from within Geographical Information Systems such as the ArcGIS applications from Esri. Data for the various derived products (previously available only as Excel spreadsheets) are now provided as shapefiles at the site level to assist in quick integration of these products for GIS analysis.
