B. Greg Mitchell in OpenAIREGlobal climate change and other anthropogenic stressors have heightened the need to rapidly characterize ecological changes in marine benthic communities across large scales. Digital photography enables rapid collection of survey images to meet this need, but the subsequent image annotation is typically a time consuming, manual task. We investigated the feasibility of using automated point-annotation to expedite cover estimation of the 17 dominant benthic categories from survey-images captured at four Pacific coral reefs. Inter- and intra- annotator variability among six human experts was quantified and compared to semi- and fully- automated annotation methods, which are made available at coralnet.ucsd.edu. Our results indicate high expert agreement for identification of coral genera, but lower agreement for algal functional groups, in particular between turf algae and crustose coralline algae. This indicates the need for unequivocal definitions of algal groups, careful training of multiple annotators, and enhanced imaging technology. Semi-automated annotation, where 50% of the annotation decisions were performed automatically, yielded cover estimate errors comparable to those of the human experts. Furthermore, fully-automated annotation yielded rapid, unbiased cover estimates but with increased variance. These results show that automated annotation can increase spatial coverage and decrease time and financial outlay for image-based reef surveys.

La hausse de la température des océans du monde est devenue une menace majeure pour les récifs coralliens à l'échelle mondiale à mesure que la gravité et la fréquence du blanchiment massif des coraux et des événements de mortalité augmentent. En 2005, les températures océaniques élevées dans l'Atlantique tropical et les Caraïbes ont entraîné l'événement de blanchiment le plus grave jamais enregistré dans le bassin. Les outils basés sur les satellites ont fourni des avertissements aux gestionnaires de récifs coralliens et aux scientifiques, guidant à la fois le moment et l'emplacement des observations sur le terrain des chercheurs alors que des conditions anormalement chaudes se développaient et se répandaient dans la grande région des Caraïbes de juin à octobre 2005. Les enquêtes de terrain sur le blanchiment et la mortalité ont dépassé les efforts antérieurs en détail et en étendue, et ont fourni une nouvelle norme pour documenter les effets du blanchiment et pour tester les prévisions actuelles et les produits de prévision. Des collaborateurs de 22 pays ont entrepris la documentation la plus complète à ce jour sur le blanchiment à l'échelle du bassin et ont constaté que plus de 80 % des coraux blanchis et plus de 40 % sont morts sur de nombreux sites. Le blanchiment le plus sévère a coïncidé avec les eaux les plus proches d'une piscine chaude de l'Atlantique occidental qui était centrée à l'extrémité nord des Petites Antilles. Le stress thermique au cours de l'événement de 2005 a dépassé tout ce qui a été observé dans les Caraïbes au cours des 20 années précédentes, et les températures moyennes régionales ont été les plus chaudes depuis plus de 150 ans. La comparaison des données satellitaires avec les enquêtes sur le terrain a démontré une relation prédictive significative entre le stress thermique accumulé (mesuré à l'aide des semaines de chauffage de degré de NOAA Coral Reef Watch) et l'intensité de blanchiment. Ce blanchissement et cette mortalité sévères et généralisés auront sans aucun doute des conséquences à long terme sur les écosystèmes récifaux et suggèrent un avenir troublé pour les écosystèmes marins tropicaux sous un climat qui se réchauffe. El aumento de la temperatura de los océanos del mundo se ha convertido en una gran amenaza para los arrecifes de coral a nivel mundial a medida que aumentan la gravedad y la frecuencia de la decoloración masiva de los corales y los eventos de mortalidad. En 2005, las altas temperaturas oceánicas en el Atlántico tropical y el Caribe dieron lugar al evento de blanqueamiento más severo jamás registrado en la cuenca. Las herramientas basadas en satélites proporcionaron advertencias para los administradores y científicos de arrecifes de coral, guiando tanto el momento como la ubicación de las observaciones de campo de los investigadores a medida que se desarrollaron condiciones anómalamente cálidas y se extendieron por toda la región del Gran Caribe de junio a octubre de 2005. Las encuestas de campo sobre blanqueamiento y mortalidad superaron los esfuerzos previos en detalle y extensión, y proporcionaron un nuevo estándar para documentar los efectos del blanqueamiento y para probar productos pronosticados y pronosticados. Colaboradores de 22 países llevaron a cabo la documentación más completa sobre el blanqueamiento a escala de cuenca hasta la fecha y descubrieron que más del 80% de los corales blanqueados y más del 40% murieron en muchos sitios. El blanqueamiento más severo coincidió con las aguas más cercanas a una piscina cálida del Atlántico occidental que se centraba en el extremo norte de las Antillas Menores. El estrés térmico durante el evento de 2005 superó cualquier temperatura observada en el Caribe en los 20 años anteriores, y las temperaturas promedio regionales fueron las más cálidas en más de 150 años. La comparación de los datos satelitales con los estudios de campo demostró una relación predictiva significativa entre el estrés por calor acumulado (medido utilizando las semanas de calentamiento de grado de NOAA Coral Reef Watch) y la intensidad del blanqueamiento. Este severo y generalizado blanqueamiento y mortalidad sin duda tendrá consecuencias a largo plazo para los ecosistemas de arrecifes y sugiere un futuro problemático para los ecosistemas marinos tropicales bajo un clima más cálido. The rising temperature of the world's oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin.Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers' field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005. Field surveys of bleaching and mortality exceeded prior efforts in detail and extent, and provided a new standard for documenting the effects of bleaching and for testing nowcast and forecast products. Collaborators from 22 countries undertook the most comprehensive documentation of basin-scale bleaching to date and found that over 80% of corals bleached and over 40% died at many sites. The most severe bleaching coincided with waters nearest a western Atlantic warm pool that was centered off the northern end of the Lesser Antilles.Thermal stress during the 2005 event exceeded any observed from the Caribbean in the prior 20 years, and regionally-averaged temperatures were the warmest in over 150 years. Comparison of satellite data against field surveys demonstrated a significant predictive relationship between accumulated heat stress (measured using NOAA Coral Reef Watch's Degree Heating Weeks) and bleaching intensity. This severe, widespread bleaching and mortality will undoubtedly have long-term consequences for reef ecosystems and suggests a troubled future for tropical marine ecosystems under a warming climate. أصبح ارتفاع درجة حرارة محيطات العالم تهديدًا كبيرًا للشعاب المرجانية على مستوى العالم مع زيادة شدة وتواتر أحداث ابيضاض المرجان الجماعي والوفيات. في عام 2005، أدت درجات حرارة المحيطات المرتفعة في المحيط الأطلسي الاستوائي ومنطقة البحر الكاريبي إلى أشد حدث تبييض تم تسجيله على الإطلاق في الحوض. قدمت الأدوات القائمة على الأقمار الصناعية تحذيرات لمديري وعلماء الشعاب المرجانية، حيث وجهت توقيت وموقع الملاحظات الميدانية للباحثين حيث تطورت الظروف الدافئة بشكل غير طبيعي وانتشرت في جميع أنحاء منطقة البحر الكاريبي الكبرى من يونيو إلى أكتوبر 2005. تجاوزت المسوحات الميدانية للتبييض والوفيات الجهود السابقة بالتفصيل والمدى، ووفرت معيارًا جديدًا لتوثيق آثار التبييض واختبار المنتجات الآنية والمتوقعة. أجرى المتعاونون من 22 دولة التوثيق الأكثر شمولاً للتبييض على نطاق الحوض حتى الآن ووجدوا أن أكثر من 80 ٪ من الشعاب المرجانية المبيضة وأكثر من 40 ٪ ماتوا في العديد من المواقع. تزامن التبييض الأكثر شدة مع المياه الأقرب إلى بركة دافئة في غرب المحيط الأطلسي كانت متمركزة قبالة الطرف الشمالي لجزر الأنتيل الصغرى. تجاوز الإجهاد الحراري خلال حدث عام 2005 أي حالة لوحظت من منطقة البحر الكاريبي في السنوات العشرين السابقة، وكانت درجات الحرارة المتوسطة إقليميًا هي الأكثر دفئًا منذ أكثر من 150 عامًا. أظهرت مقارنة بيانات الأقمار الصناعية بالمسوحات الميدانية وجود علاقة تنبؤية كبيرة بين الإجهاد الحراري المتراكم (الذي تم قياسه باستخدام أسابيع التسخين بدرجة ساعة الشعاب المرجانية التابعة للإدارة الوطنية للمحيطات والغلاف الجوي) وشدة التبييض. مما لا شك فيه أن هذا التبييض والوفيات الشديدة والواسعة النطاق سيكون لها عواقب طويلة الأجل على النظم الإيكولوجية للشعاب المرجانية وتشير إلى مستقبل مضطرب للنظم الإيكولوجية البحرية الاستوائية في ظل مناخ دافئ.

Hoegh-Guldberg, O. in OpenAIREOcean acidification represents a key threat to coral reefs by reducing the calcification rate of framework builders. In addition, acidification is likely to affect the relationship between corals and their symbiotic dinoflagellates and the productivity of this association. However, little is known about how acidification impacts on the physiology of reef builders and how acidification interacts with warming. Here, we report on an 8-week study that compared bleaching, productivity, and calcification responses of crustose coralline algae (CCA) and branching (Acropora) and massive (Porites) coral species in response to acidification and warming. Using a 30-tank experimental system, we manipulated CO2levels to simulate doubling and three- to fourfold increases [Intergovernmental Panel on Climate Change (IPCC) projection categories IV and VI] relative to present-day levels under cool and warm scenarios. Results indicated that high CO2is a bleaching agent for corals and CCA under high irradiance, acting synergistically with warming to lower thermal bleaching thresholds. We propose that CO2induces bleaching via its impact on photoprotective mechanisms of the photosystems. Overall, acidification impacted more strongly on bleaching and productivity than on calcification. Interestingly, the intermediate, warm CO2scenario led to a 30% increase in productivity inAcropora, whereas high CO2lead to zero productivity in both corals. CCA were most sensitive to acidification, with high CO2leading to negative productivity and high rates of net dissolution. Our findings suggest that sensitive reef-building species such as CCA may be pushed beyond their thresholds for growth and survival within the next few decades whereas corals will show delayed and mixed responses.

AbstractThis study applied the loss after combustion (LAC) method and the acid decalcification (ADC) method to quantify different components of an excavating sponge. Samples of dried coral skeleton of Favia sp. invaded by the Indo‐Pacific excavating sponge Cliona orientalis Thiele, 1900 were used. The sponge tissue penetrated the 12‐mm‐thick samples to approximately 10 mm. The average proportional weight of organic matter, siliceous spicules, calcareous substrate and salts in the entire samples was found to be respectively 2.5%, 4.4%, 90.5% and 2.5% of dry weight applying the LAC method, and 2.9%, 5.9%, 89.0% and 2.3% of dry weight applying the ADC method. Respective volumetric proportions of the organic matter, spicules, substrate and salts were then calculated to be 6.4%, 5.5%, 85.2% and 3.0% of volume with the LAC method, and 7.4%, 7.2%, 82.7% and 2.7% of volume with the ADC method. The LAC method showed low variability of data and is simple and fast and therefore is recommended. The ADC method generated very similar results to the LAC method. However, due to the handling involved in the ADC method, more than half of the spicules may be lost and the method is therefore not recommended unless careful data corrections are considered. In addition, the buoyant weight method was used to quantify actual substrate weight in the fresh sponge‐substrate samples. This method was found to be at least 97% effective, revealing that buoyant weights can potentially be used to quantify bioerosion rates of excavating sponges. To our knowledge, this is the first study to systemically quantify organic and inorganic components of an excavating sponge and its calcareous substrate, providing improved standard methods for future studies.

Dove, Sophie in OpenAIRETurf algae are a very important component of coral reefs, featuring high growth and turnover rates, whilst covering large areas of substrate. As food for many organisms, turf algae have an important role in the ecosystem. Farming damselfish can modify the species composition and productivity of such algal assemblages, while defending them against intruders. Like all organisms however, turf algae and damselfishes have the potential to be affected by future changes in seawater (SW) temperature and pCO2. In this study, algal assemblages, in the presence and absence of farming Pomacentrus wardi were exposed to two combinations of SW temperature and pCO2 levels projected for the austral spring of 2100 (the B1 "reduced" and the A1FI "business-as-usual" CO2 emission scenarios) at Heron Island (GBR, Australia). These assemblages were dominated by the presence of red algae and non-epiphytic cyanobacteria, i.e. cyanobacteria that grow attached to the substrate rather than on filamentous algae. The endpoint algal composition was mostly controlled by the presence/absence of farming damselfish, despite a large variability found between the algal assemblages of individual fish. Different scenarios appeared to be responsible for a mild, species specific change in community composition, observable in some brown and green algae, but only in the absence of farming fish. Farming fish appeared unaffected by the conditions to which they were exposed. Algal biomass reductions were found under "reduced" CO2 emission, but not "business-as-usual" scenarios. This suggests that action taken to limit CO2 emissions may, if the majority of algae behave similarly across all seasons, reduce the potential for phase shifts that lead to algal dominated communities. At the same time the availability of food resources to damselfish and other herbivores would be smaller under "reduced" emission scenarios. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2015) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation is 2016-05-16.

Ove Hoegh-Guldberg in OpenAIREAs atmospheric levels of CO(2) increase, reef-building corals are under greater stress from both increased sea surface temperatures and declining sea water pH. To date, most studies have focused on either coral bleaching due to warming oceans or declining calcification due to decreasing oceanic carbonate ion concentrations. Here, through the use of physiology measurements and cDNA microarrays, we show that changes in pH and ocean chemistry consistent with two scenarios put forward by the Intergovernmental Panel on Climate Change (IPCC) drive major changes in gene expression, respiration, photosynthesis and symbiosis of the coral, Acropora millepora, before affects on biomineralisation are apparent at the phenotype level. Under high CO(2) conditions corals at the phenotype level lost over half their Symbiodinium populations, and had a decrease in both photosynthesis and respiration. Changes in gene expression were consistent with metabolic suppression, an increase in oxidative stress, apoptosis and symbiont loss. Other expression patterns demonstrate upregulation of membrane transporters, as well as the regulation of genes involved in membrane cytoskeletal interactions and cytoskeletal remodeling. These widespread changes in gene expression emphasize the need to expand future studies of ocean acidification to include a wider spectrum of cellular processes, many of which may occur before impacts on calcification.

AbstractThe combination of ocean warming and acidification as a result of increasing atmospheric carbon dioxide (CO2) is considered to be a significant threat to calcifying organisms and their activities on coral reefs. How these global changes impact the important roles of decalcifying organisms (bioeroders) in the regulation of carbonate budgets, however, is less understood. To address this important question, the effects of a range of past, present and future CO2 emission scenarios (temperature + acidification) on the excavating sponge Cliona orientalis Thiele, 1900 were explored over 12 weeks in early summer on the southern Great Barrier Reef. C. orientalis is a widely distributed bioeroder on many reefs, and hosts symbiotic dinoflagellates of the genus Symbiodinium. Our results showed that biomass production and bioerosion rates of C. orientalis were similar under a pre‐industrial scenario and a present day (control) scenario. Symbiodinium population density in the sponge tissue was the highest under the pre‐industrial scenario, and decreased towards the two future scenarios with sponge replicates under the ‘business‐as‐usual’ CO2 emission scenario exhibiting strong bleaching. Despite these changes, biomass production and the ability of the sponge to erode coral carbonate materials both increased under the future scenarios. Our study suggests that C. orientalis will likely grow faster and have higher bioerosion rates in a high CO2 future than at present, even with significant bleaching. Assuming that our findings hold for excavating sponges in general, increased sponge biomass coupled with accelerated bioerosion may push coral reefs towards net erosion and negative carbonate budgets in the future.

Dove, Sophie in OpenAIRETurf algae are a very important component of coral reefs, featuring high growth and turnover rates, whilst covering large areas of substrate. As food for many organisms, turf algae have an important role in the ecosystem. Farming damselfish can modify the species composition and productivity of such algal assemblages, while defending them against intruders. Like all organisms however, turf algae and damselfishes have the potential to be affected by future changes in seawater (SW) temperature and pCO2. In this study, algal assemblages, in the presence and absence of farming Pomacentrus wardi were exposed to two combinations of SW temperature and pCO2 levels projected for the austral spring of 2100 (the B1 "reduced" and the A1FI "business-as-usual" CO2 emission scenarios) at Heron Island (GBR, Australia). These assemblages were dominated by the presence of red algae and non-epiphytic cyanobacteria, i.e. cyanobacteria that grow attached to the substrate rather than on filamentous algae. The endpoint algal composition was mostly controlled by the presence/absence of farming damselfish, despite a large variability found between the algal assemblages of individual fish. Different scenarios appeared to be responsible for a mild, species specific change in community composition, observable in some brown and green algae, but only in the absence of farming fish. Farming fish appeared unaffected by the conditions to which they were exposed. Algal biomass reductions were found under "reduced" CO2 emission, but not "business-as-usual" scenarios. This suggests that action taken to limit CO2 emissions may, if the majority of algae behave similarly across all seasons, reduce the potential for phase shifts that lead to algal dominated communities. At the same time the availability of food resources to damselfish and other herbivores would be smaller under "reduced" emission scenarios.

ABSTRACTMarine ecosystems provide critically important goods and services to society, and hence their accelerated degradation underpins an urgent need to take rapid, ambitious and informed decisions regarding their conservation and management.The capacity, however, to generate the detailed field data required to inform conservation planning at appropriate scales is limited by time and resource consuming methods for collecting and analysing field data at the large scales required.The ‘Catlin Seaview Survey’, described here, introduces 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. This enables quantitative and geo‐referenced outputs of coral reef features such as habitat types, benthic composition, and structural complexity (rugosity) to be generated across multiple kilometre‐scale transects with a spatial resolution ranging from 2 to 6 m2.The novel application of technology described here has enormous potential to contribute to our understanding of coral reefs and associated impacts by underpinning management decisions with kilometre‐scale measurements of reef health.Imagery datasets from an initial survey of 500 km of seascape are freely available through an online tool called the Catlin Global Reef Record. Outputs from the image analysis using the technologies described here will be updated on the online repository as work progresses on each dataset.Case studies illustrate the utility of outputs as well as their potential to link to information from remote sensing. The potential implications of the innovative technologies on marine resource management and conservation are also discussed, along with the accuracy and efficiency of the methodologies deployed.

Sophie Dove in OpenAIREAbstractBiological mediation of carbonate dissolution represents a fundamental component of the destructive forces acting on coral reef ecosystems. Whereas ocean acidification can increase dissolution of carbonate substrates, the combined impact of ocean acidification and warming on the microbioerosion of coral skeletons remains unknown. Here, we exposed skeletons of the reef‐building corals,Porites cylindricaandIsopora cuneata, to present‐day (Control: 400 μatm – 24 °C) and futurepCO2–temperature scenarios projected for the end of the century (Medium: +230 μatm – +2 °C; High: +610 μatm – +4 °C). Skeletons were also subjected to permanent darkness with initial sodium hypochlorite incubation, and natural light without sodium hypochlorite incubation to isolate the environmental effect of acidic seawater (i.e., Ωaragonite<1) from the biological effect of photosynthetic microborers. Our results indicated that skeletal dissolution is predominantly driven by photosynthetic microborers, as samples held in the dark did not decalcify. In contrast, dissolution of skeletons exposed to light increased under elevatedpCO2–temperature scenarios, withP. cylindricaexperiencing higher dissolution rates per month (89%) thanI. cuneata(46%) in the high treatment relative to control. The effects of futurepCO2–temperature scenarios on the structure of endolithic communities were only identified inP. cylindricaand were mostly associated with a higher abundance of the green algaeOstreobiumspp. Enhanced skeletal dissolution was also associated with increased endolithic biomass and respiration under elevatedpCO2–temperature scenarios. Our results suggest that future projections of ocean acidification and warming will lead to increased rates of microbioerosion. However, the magnitude of bioerosion responses may depend on the structural properties of coral skeletons, with a range of implications for reef carbonate losses under warmer and more acidic oceans.
