プロジェクトデータ
Our goal is to monitor the dynamics of the benthic assemblage in Abrolhos reefs. We also expected to contribute to elucidate issues applied to conservation (e.g. effectiveness of different management regimes), and restoration (factors influencing resilience), as well as to explore broader theoretical issues.

Study Area Description | The Abrolhos Bank (16˚40’, 19˚40’S—39˚10’, 37˚20’W) is a 46,000 km2 shallow water (less tan 70 m depth) enlargement of the Eastern Brazilian shelf, off southern Bahia and northern Espírito Santo States. The region encompasses the largest and richest Southwestern Atlantic coral reefs. Emerging and quasi emerging reefs are distributed in two arcs (nearshoreand offshore, 10–20 km and 70 km from the shoreline, respectively), and are surrounded by soft sediments, rhodoliths and low-lying mesophotic reefs. Fringing reefs also occur around the five islands of the Abrolhos Archipelago. |
研究の意図、目的、背景など(デザイン) | Objectives: Evaluate the dynamics of benthic communities, associating them with climatic-oceanographic conditions. Assess impacts resulting from the Fundão Disaster. Evaluate chemical mediation in the structuring of reef communities and explore the biotechnological potential of selected species. Assess the dynamics of coral bleaching. |

収集方法
We used fixed photo-quadrats demarcated with metal pins that are periodically replaced. Each benthic sampling unit is composed of a mosaic of 15 high resolution photos and covering ~70 cm2. Each sampling site has 10 sampling units. During the period monitored, some years and/or locations were not sampled due to logistical and funding constrains. Images were annotated semi-automatically with the deep neural network provided by the CoralNet platform*. Relative cover was estimated from the identification of benthic organisms below 30 random points distributed in each image (one photo-quadrat = a mosaic of 15 high resolution close-up images). Organisms were identified at nine broad taxonomic or functional groups and categorized either as slower-growing longer-lived reef builders [corals, crustose calcareous algae (CCA) and hydrocorals] or their faster-growing shorter-lived antagonists [(frondose macroalgae, turf, benthic cyanobacteria mats (BCM), zoanthids, sponges and “other organisms” (OO)]. * Beijbom O, Edmunds PJ, Roelfsema C, Smith J, Kline DI, Neal BP, et al.

Study Extent | Monitored sites include five reefs in the Abrolhos Archipelago, a set of small volcanic islands ~55 km off the coast and within the Marine National Park. Data has been acquired since 2006, mostly during the Austral summer. |
---|---|
Quality Control | We used an 80% confidence threshold (label accuracy: 95.4%, functional group accuracy: 96.9%, fraction above threshold: 53%) for the semi-automatic annotation carried out with the deep neural network of the CoralNet platform. |
Method step description:
- Benthic sampling is described in Teixeira et al. (2021).
