TL;DR: Overall reef fish density has been declining significantly for more than a decade, at rates that are consistent across all subregions of the Caribbean basin and in three of six trophic groups, indicating that Caribbean fishes have begun to respond negatively to habitat degradation.
Journal ArticleDOI
Caribbean-wide, long-term study of seagrass beds reveals local variations, shifts in community structure and occasional collapse.

TL;DR: The CARICOMP monitoring network gathered standardized data from 52 seagrass sampling stations at 22 sites across the Wider Caribbean twice a year over the period 1993 to 2007, and fifteen (43%) out of 35 long-term monitoring stations showed trends in seagRass communities consistent with expected changes under environmental deterioration.
Journal ArticleDOI
The Catlin Seaview Survey – kilometre‐scale seascape assessment, and monitoring of coral reef ecosystems
Manuel González-Rivero,Pim Bongaerts,Oscar Beijbom,Oscar Pizarro,Ariell Friedman,Alberto Rodriguez-Ramirez,Ben Upcroft,Dan Laffoley,David I. Kline,Christophe Bailhache,Richard Vevers,Ove Hoegh-Guldberg +11 more
TL;DR: The Catlin Seaview survey as discussed by the authors introduced a novel framework for large-scale monitoring of coral reefs using high-definition underwater imagery collected using customized underwater vehicles in combination with computer vision and machine learning.

TL;DR: Repeated surveys and comparisons show that automated estimation of benthic composition is equally robust in detecting change and ensuring the continuity of existing monitoring data, and can be accelerated by at least 200x and at a fraction of the cost.
Journal ArticleDOI
Scaling up Ecological Measurements of Coral Reefs Using Semi-Automated Field Image Collection and Analysis

TL;DR: This approach allows a rapid collection of in-situ observations at larger spatial scales (km) than previously possible, and provides a pathway to link, calibrate, and validate broader analyses across even largeratial scales (10–10,000 km2).
