Background The rising temperature of the world's oceans has become a major threat to coral reefs globally as severity and frequency mass bleaching mortality events increase. In 2005, high ocean temperatures in tropical Atlantic Caribbean resulted most severe event ever recorded basin. Methodology/Principal Findings Satellite-based tools provided warnings for reef managers scientists, guiding both timing location researchers' field observations anomalously warm conditions developed spread...
Ecosystem monitoring is central to effective management, where rapid reporting essential provide timely advice. While digital imagery has greatly improved the speed of underwater data collection for benthic communities, image analysis remains a bottleneck in observations. In recent years, evolution artificial intelligence recognition been evident its broad applications modern society, offering new opportunities increasing capabilities coral reef monitoring. Here, we evaluated performance...
The CARICOMP monitoring network gathered standardized data from 52 seagrass sampling stations at 22 sites (mostly Thalassia testudinum-dominated beds in reef systems) across the Wider Caribbean twice a year over period 1993 to 2007 (and some cases up 2012). Wide variations community total biomass (285 >2000 g dry m−2) and annual foliar productivity of dominant T. testudinum (<200 were found among sites. Solar-cycle related intra-annual leaf detected latitudes > 16°N. Hurricanes had little no...
ABSTRACT Marine ecosystems provide critically important goods and services to society, hence their accelerated degradation underpins an urgent need take rapid, ambitious informed decisions regarding conservation management. The capacity, however, generate the detailed field data required inform planning at appropriate scales is limited by time resource consuming methods for collecting analysing large required. ‘Catlin Seaview Survey’, described here, introduces a novel framework large‐scale...
Ecological measurements in marine settings are often constrained space and time, with spatial heterogeneity obscuring broader generalisations. While advances remote sensing, integrative modelling meta-analysis enable generalisations from field observations, there is an underlying need for high-resolution, standardised geo-referenced data. Here, we evaluate a new approach aimed at optimising data collection analysis to assess broad-scale patterns of coral reef community composition using...
Karimunjawa National Park is one of Indonesia’s oldest established marine parks. Coral reefs across the park are being impacted by fishing, tourism and declining water quality (local stressors), as well climate change (global pressures). In this study, we apply a multivariate statistical model to detailed benthic ecological datasets collected Karimunjawa’s coral reefs, explore drivers community at level. Eighteen sites were surveyed in 2014 2018, before after 2016 global mass bleaching...
The Pacific Decadal Oscillation (PDO) is a large-scale climatic phenomenon modulating ocean-atmosphere variability on decadal time scales. While precipitation and river flow in the Great Barrier Reef (GBR) catchments are sensitive to PDO phases, extent which influences coral reefs poorly understood. Here, six Porites cores were used produce composite record of luminescence (runoff proxy) identify drivers terrestrial influence Keppel reefs, southern GBR. We found that skeletal effectively...

En general, la coralina fue alta (55.1% - 65.7%) baja (28.8% 37.5%), con una significativa variación entre años, más notablemente áreas someras. Las diferencias tanto coral como estuvieron presentes desde que comenzó el...
<span>Desde 1998 el “Sistema Nacional de Monitoreo Arrecifes Coralinos Colombia” SIMAC, ha observado la ocurrencia enfermedades coralinas y blanqueamiento en arrecifes colombianos (estaciones fijas Isla San Andrés, Tayrona, Islas del Rosario, Bernardo Urabá Chocoano). Para estimar se examinado anualmente un total 126 bandas permanentes (10x2m), dispuestas diferentes rangos profundidad las áreas arrecifales objeto estudio. El análisis información obtenida entre 2004 revela que Andrés...

Entre 1998 y 2004 se monitorearon un total 32 parcelas permanentes ubicadas a diferentes niveles profundidad seis áreas arrecifales del Caribe colombiano. Los patrones temporales algas corales fueron evaluados mediante varianza medidas repetidas. promedios generales indicaron que las dominaron mayoría evaluadas, variando 30.3%...
Coastal ecosystems and the livelihoods they support are threatened by stressors acting at global local scales. Here we used data produced Caribbean Marine Productivity program (CARICOMP), longest, largest monitoring in wider Caribbean, to evidence local-scale (decreases water quality) global-scale (increases temperature) across basin. Trend analyses showed that visibility decreased 42% of stations, indicating chronic widespread. On other hand, only 18% stations increases temperature would be...

Abstract Coral reefs are declining rapidly in response to unprecedented rates of environmental change. Rapid and scalable measurements how benthic ecosystems responding these changes critically important. Recent technological developments associated with the XL Catlin Seaview Survey have begun provide high‐resolution 1‐m 2 photographic quadrats ~1.8–2 km coral at 10 m depth by using a semi‐autonomous image collection SeaView II camera system ( SVII ). The rapid images can result being taken...
Twenty coral formations were evaluated in the area of Santa Marta terms of: 1) composition and abundance principal substrate categories 2) prevalence diseases bleaching. To obtain information, bands 10 x 1 m 2 used, respectively. A total 33 species hard corals registered. Algae components with major cover, nonetheless, averages varied widely study (coral= 4.0 ± 0.9 %-62.0 7.2 %; algae = 30.6 11.0 %-78.3 3.0 %). The highest cover Colpophyllia natans, Diploria strigosa, Acropora palmata,...
En respuesta al proceso de deterioro los arrecifes coralinos colombianos en las últimas tres décadas, y con el propósito establecer un sistema vigilancia para manejo apropiado estos valiosos ecosistemas, Instituto Investigaciones Marinas Costeras (INVEMAR) desde 1998 ha impulsando puesto marcha Sistema Nacional Monitoreo Arrecies Coralinos Colombia (SIMAC), apoyo varias instituciones colombianas. El SIMAC operado sin interrupción por más ocho años, periodo durante cual se han establecido 63...
Live coral predation by fish was evaluated in two bays of the Tayrona National Natural Park (Colombia), as a possible biological agent causing mortality. Visual censuses were used to identify most important predator. Predation incidence determined examining all colonies present permanent belt transects (20 x 2 m) reef environments (one dominated Colpophyllia natans and other one Montastraea faveolata), for climatic seasons (rainy dry seasons). The parrotfish Sparisoma viride predator due its...
Quantification is the task of estimating class-distribution a data-set. While typically considered as parameter estimation problem with strict assumptions on data-set shift, we consider quantification in-the-wild, two large scale data-sets from marine ecology: survey Caribbean coral reefs, and plankton time series Martha's Vineyard Coastal Observatory. We investigate several methods literature indicate opportunities for future work. In particular, show that deep neural network can be...
Addressing the global decline of coral reefs requires effective actions from managers, policymakers and society as a whole. Coral reef scientists are therefore challenged with task providing prompt relevant inputs for science-based decision-making. Here, we provide baseline dataset, covering 1300 km tropical habitats globally, comprised over one million geo-referenced, high-resolution photo-quadrats analysed using artificial intelligence to automatically estimate proportional cover benthic...
Abstract This paper describes benthic coral reef community composition point-based field data sets derived from georeferenced photoquadrats using machine learning. Annually over a 17 year period (2002–2018), were collected downward-looking that capture an approximately 1 m 2 footprint along 100 m–1500 transect surveys distributed the slope and across flat of Heron Reef (28 km ), Southern Great Barrier Reef, Australia. Benthic for was automatically interpreted through deep learning, following...
