Objectives: Global warming effects, including the contribution of several anthropic activities such as the burning of fossil fuels and deforestation, can affect biomes and many physical and chemical features of the oceans. These effects over the dynamics and structure of phytoplankton (including cyanobacteria) are not yet well understood. However, shifts in duration and frequency of meteorological events have been associated with the increasing in harmful algal blooms (HABs) across many coastal regions worldwide. This proposal aims at assessing direct and indirect effects of climate changes over these phytoplankton blooms in the Atlantic Ocean (between 0º35ºS), taking into account environmental database analysis combined with notifications of HABs in Brazil and, also, further lab experiments with target species that form known HABs. As far as possible, there will be compiled physical, meteorological and hydrographical information as well phytoplankton data across the study region since 1970s. With this dataset, we will evaluate the spatial and temporal environmental variability linking to bursts of HABs. Also, we intend to build predictive models of these biological events for the Brazilian coast and to carry on bioassays with certain strains of HAB obtained in some local laboratories. Temperature and nutrient concentration (nitrate, phosphate) are the variables chosen a priori to be tested. This project is being conducted at the Oceanography Institute of the Federal University of Rio Grande (Brazil) as my pos-doc fellowship research.

Objectives: The European aquaculture sector supports several North Atlantic coastal communities. The effects of harmful algal blooms (HABs) and microbial pathogens can have a massive impact on this sector. HABs negatively affect shellfish and finfish aquaculture operations through the rapid accumulation of biotoxins in farmed shellfish consumed by humans, and by killing entire stocks of farmed fish due to toxins, physical damage and deoxygenation. The estimated economic impact of HABs in EU waters may be as high as €919 million per year. Prevention of natural HABs is not possible but reliable early warnings may facilitate effective mitigation measures to safeguard public health and private business operations. 
The main objective of Project PRIMROSE is to provide a reliable standard, automated system for reporting and forecasting HABs and microbial events that impact aquaculture operations in European coastal waters. We will build on existing HAB early warning systems developed by our previous successful forecasting system during its predecessor, Project ASIMUTH (reported in a special edition of Harmful Algae, 2016).  New features of PRIMROSE will include; an expanded system for new fish- and shellfish-producing areas; improved HAB forecasts with greater resolution; a wider suite of parameters; an evaluation of the potential for mitigation; new index based risk assessments; and a valuable information service for policy makers, risk regulators, food safety authorities and the aquaculture sector, from Shetland to Canary Islands. The new forecast will include microbial risk (eg. E. coli, Norovirus, Vibrio) and environmental/ climate impacts, in addition to improved HAB predictions. 
PRIMROSE will benefit from improved spatial resolution, utilising new generation Sentinel data products for the main aquaculture production areas in France, Ireland, Portugal, Spain and the UK. Improved ASIMUTH-developed methodologies for producing HABs forecasts will result from operational oceanographic forecasts, downscaled regional hydrodynamic models, novel satellite data, phytoplankton/ biotoxin monitoring data and expert evaluation. PRIMROSE will upgrade the current HAB forecast service to the regional scale; providing mesoscale trans-national HAB and microbial risk information, risk assessments and knowledge exchange with the international user community. We intend to maintain close involvement/co-development with industry partners throughout the project to ensure maximum impact of the project outputs. 
New information from the Marine Strategy and Water Framework Directive monitoring programs; from a new generation of sensors aboard the Sentinel suite of satellites, and sensors collecting underway data aboard ferries, will also be utilised for the alert system. The aquaculture sector relies on sufficient early warning of harmful events, so that effective mitigation measures can be utilised. PRIMROSE will both develop a trans-national short- to medium-term risk forecast, and a long-term assessment of climate impact on HABs and pathogens.
The main objective of PRIMROSE is to provide a reliable standard, automated system for reporting and forecasting HABs and microbial events that impact aquaculture operations in European coastal (AA) waters.

Objectives: Harmful algal blooms in benthic system (BHABs) have been increased rapidly under the backgrounds of global climate changes and human activities. The detrimental effects of BHABs on marine coral ecosystems and human health make it one of the research priorities in HAB science nowadays. Toxins produced by some species of Gambierdiscusare associated with a seafood illness - Ciguatera Fish Poisoning (CFP). From scientific perspective, the following key questions need to be answered: What are the biodiversity/distribution patterns of BHABs in space and time? What is the status of BHABs threat to coral ecosystems? How BHABs respond to the environmental changes? What are the possible relationships with the seasonal benthic community composition? What is the best suited of detection technologies that can be developed to support monitoring of BHAB and their toxins? This study intends to study the BHAB species assemblages at spatial and temporal scales and identify mechanisms underlying the community dynamics and their interactions with the coral reef ecosystems. A dataset on the biodiversity and toxicity of BHAB species, along with environmental parameters and health status of coral ecosystems, will be established for the investigated areas based on regular, systematic field-based surveys. By measuring the environmental variability and determining threshold levels of BHAB-related phycotoxins for developmental and behavioural endpoints of fishes, a holistic assessment of the ecological health risks that BHABs posed to coral ecosystems can be conducted. A monitoring framework could be developed for allowing a sustainable use of goods and services provided by the coral ecosystems. It is foresee that the outcomes of this study will be substantial in providing a reference towards an internationally research in BHABs.

 

Some activities: 

* Training workshop “Applying analytical method for detecting ciguatoxin in fish”. Organized by IOC WESTPAC Toxic Marine Organisms (WESTPAC-TMO) at Institute of Oceanography, Nha Trang from 5-9 April 2018. Responsible: Dr Leaw.

Objectives:

Harmful algae blooms (HABs) negatively impact both New Zealand and French seafood sectors, with risks to both seafood exports and the health of recreational fishers. Many toxic dinoflagellate species develop blooms and have complex life cycles with a resting stage or cyst. Little is known about the direct uptake of dinoflagellate cysts into the food chain or whether it poses a health risk to seafood consumers. This two-year project will enable New Zealand experts to establish a collaborative relationship with French scientists at Ifremer and MARBEC who are experts in HAB cysts. The specific aim of this project is to identify benthic life stages of three high priority toxic dinoflagellate groups, namely, Alexandrium, Azadinium and Vulcanodinium. Cysts will be isolated from sediments around New Zealand and France. Cyst morphology, molecular genetic composition and toxicity will be determined. By identifying and establishing the abundance of benthic cysts beds in both France and New Zealand, predictions of blooms can be made and their likely risk to consumers assessed.

Cyst Workshop

Some activities: 

* A workshop (included picture above) on morphological and molecular identification techniques of toxic HAB species, led by Drs Mertens and Smith, was held in New Zealand (12-14 February 2018) to assess both morphological and novel molecular methods for cyst identification. It also provided training for those involved with monitoring programmes internationally (both for micro-algae and invasive species).

* A follow-up workshop led by Drs Smith and Mertens, to coincide with ICHA 2018 in Nantes (France; 21-26 October 2018) will ensure the transfer of expertise and uptake of methods internationallythe transfer of expertise and uptake of methods internationally.

Objectives: European coastal ecosystems are changing as a result of interactions between a number of drivers including overfishing, pollution, and climate change. Changes in marine ecosystems will impact on human health, food safety and the future sustainability of sectors including aquaculture, fisheries and tourism. Climate projection information is plentiful and there is considerable activity in marine ecosystem impact modelling; however, a disconnect remains between delivery of this information and its effective uptake by end users and policy makers. The CoCliME project will co-develop and co-produce a set of regionally focused climate services to address key impact areas including human health, aquaculture, fisheries and tourism across the regional seas of Europe. The developed services, and associated decision support tools, will empower and support vulnerable coastal sectors to accelerate adaptive decision-making and feed into key governance mechanisms such as the Marine Strategy Framework Directive, Marine Spatial Planning, and local, national and European adaptation planning. The project team brings together a newly established consortium of boundary organisation experts in co-development of climate services with leaders in marine ecosystem research, regional ocean climate modellers, and, at its heart, a number of targeted users and decision makers in each region. The project will offer an innovative and user-focused approach and the development of a societally relevant climate service framework, in addition to the bespoke climate services, that will be transferable to other regions, impact areas, users and marine ecosystem vulnerabilities. Through a regional case study approach, the specific needs of national and European marine ecosystem impact and adaptation planners and regulatory authorities will be identified and addressed through an evidence-based and iterative process designed to feed into climate adaptation strategies across the EU and beyond. CoCliME is part of the ERA4CS, an ERA-NET initiated by JPI Climate, and funded by EPA (IE), ANR (FR), BMBF (DE), UEFISCDI (RO), RCN (NO) and FORMAS (SE), with co-funding by the European Union (Grant 690462).

 

Some activities:

* A coordinated sampling in European waters to determine the presence of benthic harmful dinoflagellates, with a special focus on the genus Ostreopsis is been conducted in the summer of 2018.
