What controls carbon export in the world's dustiest eastern boundary upwelling system? By combining satellite-derived productivity budgets, Lagrangian particle tracking and deep-ocean sediment-trap observations, our new study disentangles the seasonal roles of upwelling, ocean circulation and Saharan dust in the Canary Current System.

CBIOMES is a multi-institution effort seeking to characterise biogeography of key marine microbes at basin and seasonal scales, to ask how organismal characteristics and interactions shape these patterns, and to understand and quantify the relationship between biogeography and elemental cycles.

The potential of using new AI tools to understand global natural phenomena was emphasised during the seminar, by combining ocean models, satellite data and field observations, and through maximizing the use of ocean data – even those of lower quality – and still finding significant results.

Based on satellite data spanning 1999–2021, Afonso Ferreira and colleagues reveal that the highest anchovy recruitment appears to coincide with the annual spawning peak occurring from April through June, often linked to the positive phase of the Winter North Atlantic Oscillation (NAOW).

Among the main points of the meeting was to present an overview of the progress and project deliverables linked to WP5 Advancing Earth System Science, and WP6 Transferring Science into Solutions for Society, for which all Earth Science Case and Demonstrations leaders presented the work performed during the project.

The event was part of PRIMUS WP6 aimed at conducting demonstrations that transfer science into developing societal solutions, building on PRIMUS science case studies (EBUS and aquaculture, fisheries and eutrophication monitoring), and working together with scientific, agency, policy and commercial early adopters.

The COP to the UN Framework Convention on Climate Change (UNFCCC) is an annual international climate summit that gathers leaders from across the world (197 countries plus the European Union) to work together on solutions to tackle climate change, including the Paris Agreement.

The symposium was hosted by the Plymouth Marine Laboratory (PML) to celebrate the scientific life of Prof. Trevor Platt and carry forward his legacy in ocean research and international collaboration, by gathering experts and institutions from diverse backgrounds to explore the challenges and solutions related to sustainable management of the ocean.

FEC is a Global Research Network of Future Earth acting as a platform for deepening understanding of complex Earth systems and human dynamics across different disciplines, translating sustainability knowledge into action by using it to underpin evidence-based policies and strategies for sustainable development.

The study involves a comparative analysis of the 25-year time-series of NPP data for the Iberian, Canary and Benguela systems in relation to upwelling indices and variations in climate indices, such as the North Atlantic Oscillation (NAO). 

The conference was organised by the City Hall of Torres Vedras (Portugal) at the Environmental Interpretation Centre of the Local Natural Reserve Foz Azul, aimed at creating awareness in the general public to the many ecosystem services that seaweeds offer and their contribution to the well-being of our planet.

This special issue, in which PRIMUS member Catarina V. Guerreiro (MARE-FC.ID) has been invited as guest editor, is an outcome of the Open Science Conference on EBUS: Past, Present and Future & Second International Conference on the Humboldt Current System. The deadline for submissions is 31 January 2024!

The workshop was hosted by the Institute for Data Science and Artificial Intelligence, aimed at facilitating the share of scientific discoveries and methods, the exploration of emerging applications and new opportunities for remote sensing and machine learning, and the fostering of new collaborations and network-building.

Afonso Ferreira (MARE) and colleagues report on SST being the main driver of sardine growing from very young, small larvae state to older, larger-sized fish in Atlanto-Iberian waters. Other factors include specific physical conditions favouring larval feeding and retention, such as the shallowing of the ocean mixed layer and the transport of water masses towards the more coastal regions.

BICEP has recently launched a valuable animation about the importance of marine phytoplankton as the main player in the ocean biological carbon pump, while also highlighting how Earth Observation data contribute crucially to unravel the functioning of biogeochemical ocean-related processes.

The TPSF  is an international organisation established in 2021 to stimulate capacity building in science, research, and environment-related education with special focus on the oceans, aiming at promoting a more sustainable governance of our planet for the future generations.

The expedition was aimed at collecting new in situ data to explore the multiple drivers of phytoplankton (export) productivity in a region of the Canary Current EBUS bordered by the single most important source of atmospheric dust emission on a global scale: the Saharan and Sahel Desert regions.

Bror Jönsson and Shubha Sathyendranath from PML have developed a new method to estimate dominating timescales of variability from datasets where up to 90% of the data is missing: MOving Standard deviation Saturation (MOSS). Their work has just been published in Remote Sensing of Environment and represents the first scientific output from PRIMUS.

More than two months after the first expedition of PRIMUS-related project e-IMPACT, Javier Arístegui and Xosé A. Álvarez-Salgado returned on RV Sarmiento de Gamboa to look for more clues on the impact of eddy-related processes on plankton variability in the Canary Current EBUS.
