For the IMBeR and CLIOTOP Community

Vale Joel Llopiz

Joel Llopiz was a long-time IMBeR and CLIOTOP member, contributing as a researcher, Early life history working group lead (2008-2015), and former CLIOTOP co-chair (2018-2021).


In January 2026, Joel Llopiz passed away from glioblastoma – an aggressive form of brain cancer. At 48 years, this is unfair in so many ways that trivialise this science obituary Joel K. Llopiz | Falmouth Obituaries. While we mourn Joel, we want to share and celebrate some of his contribution to scientific discovery and to friendship in our community.

Joel joined the CLIOTOP community when he attended and present a poster on his PhD research at the 1st CLIOTOP symposium, in 2007 held in La Paz Mexico. He was awarded his PhD in 2008 by the University of Miami in Florida, with a dissertation titled “The trophic ecologies of larval billfishes, tunas, and coral reef fishes in the Straits of Florida: Piscivory, selectivity, and niche separation”, supervised by Dr Bob Cowen. After a couple of post-docs at Miami and then the Woods Hole Oceanographic Institution (WHOI), Joel joined the WHOI as an assistant scientist in 2012, where he remained for the rest of his career as he progressed through academic ranks.

Joel’s early research involved the first ever examination of the diets and feeding success of Atlantic bluefin tuna larvae in the Gulf of Mexico, which showed bluefin larvae have a notably high degree of feeding success, a high reliance on appendicularians, and a relatively early onset of piscivory (consuming other fish larvae), including the frequent occurrence of cannibalism (Llopiz et al., 2015).

He shared his passion for things larval with graduate students and classes at WHOI, and diversified research activities in the lab and on research vessels to study impacts on other marine species in north-east USA, including eel, sand lance and forage fishes such as Atlantic herring, alewife, blueback herring, Atlantic mackerel, and Atlantic butterfish. Joel’s research team used both traditional gut content analysis coupled with stable isotopes to find surprising inter-specific distinctions in diets, given that these planktivorous species exhibit substantial spatial overlap. They also revealed marked spatial and temporal variability within species (Suca et al., 2018). Joel also joined and led research abroad several Arctic research voyages, an area he was excited to visit and understand.

In his own words, written in 2022 for a very formal process, his introduction to his research summary shows his personality and passion:

“I often struggle to describe the integrative nature of my research without a bit of further explanation. When meeting new colleagues, I probably say most frequently “I’m a fish and zooplankton ecologist,” but I’m never fully satisfied with this answer. “Fisheries oceanographer” is most accurate, since it is a formal term for those who study how fish ecology, behavior, and distributions are influenced by the physical and biological environment—which is exactly what we do in my lab. But this term is confusing to many since we do not work on fisheries per se. Other somewhat suitable terms could include biological oceanographer, forage fish ecologist, or larval fish ecologist. (“Fishy oceanographer” would be close to perfect, but I doubt this will catch on.) None of these descriptions, however, fully capture what I enjoy most about science: collaboration and education. Both of these facets of my work keep me motivated and invigorated.”

Joel also continued his involvement in IMBeR and CLIOTOP, attending IMBeR-wide Open Science meetings, IMBIZO events, and CLIOTOP symposia from Bergen to Brest and beyond. He would arrive at these meetings with back-streets restaurant suggestions, and we’d wander those streets looking for these places, all before mobile phones made it easy. He was a fan of shared houses when we attended international meetings, and those experiences were so much more fun than staying in a hotel and riding an elevator to the meeting floor. Of course, each time we travel for work, we leave behind family and commitments, but these face-to-face experiences make our professional lives so much richer, and I thank Joel’s family for sharing him in this parallel life with us over all those times. While our photos may be of stiff meeting attendees, and we worked hard through agendas and to share research, the time spent with Joel led to his many enduring friendships in our community.

Joel was a natural teacher and leader, generous with his time and knowledge, and deeply invested in the growth of others. He led not through authority, but through curiosity, kindness, and example, encouraging early-career scientists and peers alike to think broadly and trust their scientific instincts. Many in our community benefited from his quiet guidance and steady encouragement. His legacy lives on not only in his science, but in the confidence, collaborations, and careers he helped to shape.

Across his career, Joel was a valued member of many research efforts – he brought unique skills, appreciation of observational data, and no ego. We will continue to share the values that Joel espoused and we miss his warmth and generosity.

Economic impacts of sargassum events

in Puerto Rico, USVI, and coastal Florida

Authors: D. Jin, A. Wang, T. Dalton

 

Journal: Harmful Algae


The frequency, intensity, and distribution of sargassum events have been rising in the Caribbean region in recent years causing social and economic disruptions. We develop estimates of the scale of annual economic impacts on local economies of sargassum events using multi-sector economic impact models for Puerto Rico, U.S. Virgin Islands, and coastal Florida. Using field observations from the Sargassum Watch database, we validate the current sargassum forecast in the region. We show that the forecast is performing well and that sargassum season has started earlier and lasted longer in recent years. The high-risk regions for sargassum inundation include Puerto Rico, U.S. Virgin Islands, and southeast coastal areas in Florida. Results of the study show that sargassum events are expected to cause significant negative economic impacts, in multimillion dollars each year, across the study regions, and the impact may be in billions of dollars along Florida’s Atlantic coast. These results provide important input to the planning process in deciding the investments in future sargassum response and cleanup. They can also facilitate targeted data collection and valuation efforts to develop more accurate measures of economic losses.

The Asia-Pacific Region (APR) encompasses a vast geographical area rich in marine biodiversity that plays critical roles in global ecological stability and climate regulation, but it also faces daunting challenges in maintaining these roles under global change. Environmental dynamics in the APR manifest regularly over a range of timescales, including storms, earthquakes, floods, and extreme heat events. Further, coastal and marine ecosystems, including extensive commercial fisheries and coral reefs, are under threat from intense resource extraction and increasingly frequent marine heatwaves. Knowledge gaps for understanding these complex systems are aggravated by substantial barriers to cross-national efforts caused by the region’s vast diversity of cultures, languages, socioeconomics, politics, and management practices. Effective management of marine resources in the APR will necessitate multidisciplinary research based on continuous, region-wide observations supported by robust collaborations. In 2023, we gathered APR researchers across disciplines to discuss these issues and find solutions during a thematic seminar and workshop program at Tohoku University in Japan. Based on the results of this program, we present a review of the current state of APR marine ecosystems, raise key questions addressable through multidisciplinary approaches, and identify future priorities for the region. We conclude that sustaining biodiversity, ecosystem functions, and climate resilience in the APR will depend on stronger interdisciplinary collaboration, better integration of biological and geophysical data, and broader access to marine observations. These efforts are both urgent and essential for supporting better science-based policy decisions to address the escalating effects of global change on marine systems across the region.

Animal movements affect their exposure to threats and the efficacy of conservation measures, such as marine protected areas (MPAs). However, many species’ movements are difficult to reconstruct from available datasets, hampering conservation efforts. This is especially the case for aquatic species that rarely surface, for which data are often limited to observations from acoustic telemetry (detections) and ancillary sensors. Here, we pioneer the use of state-of-the-art particle algorithms to model movements, integrate datasets, and assess MPA design, leveraging a case study of a Critically Endangered elasmobranch. Our algorithms led to 5-fold improvements in space-use maps and 30-fold improvements in residency estimates compared to prevailing methods. By integrating tracking datasets, we were uniquely able to examine movements beyond acoustic receivers, MPA-scale residency, and specific habitats beyond protected areas that warrant protection. This work reveals a modeling framework that enhances the conservation value of acoustic telemetry, supporting analyses of MPA efficacy worldwide.

Seasonal enhancement of the viral shunt

catalyzes a subsurface oxygen maximum in the Sargasso Sea

Journal: Nature Communications

 

Subsurface oxygen maxima (SOMs) occur directly beneath the mixed layer of stratified water columns across oligotrophic open ocean basins and have been associated with physical transport processes and localized increases in phytoplankton net primary productivity (NPP). We explore the hypothesis that viral lysis (i.e., the ‘viral shunt’) increases nutrient recycling and enhances NPP, supporting SOM formation in stratified water columns, focusing on a recurring SOM at the Bermuda Atlantic Time Series (BATS) in the Sargasso Sea. Reanalysis of historical BATS data showed enhanced Prochlorococcus and virus-like particle abundances associated with SOMs. Instances of high rates of primary and secondary production observed with oxygen supersaturation further implicate a biological mechanism for SOM formation. Leveraging metatranscriptomes, metaviromes, and polony-based data collected during a Lagrangian cruise (October 2019), we link the viral shunt to SOMs, including evidence of elevated cyanophage abundance and infection of Prochlorococcus, and transcriptomic evidence of increased organic matter uptake (i.e., catabolic activity) by copiotrophic bacteria. Cruise data also showed Prochlorococcus nitrogen metabolism transcripts consistent with increased responsiveness to bacterial remineralization. These findings illustrate the biogeochemical impacts of enhanced viral lysis in marine systems, including the potential role of the viral shunt in facilitating SOM formation in the oligotrophic oceans.

Four-hour thunderstorm nowcasting

using a deep diffusion model for satellite data

Authors: K. Dai, X. Li, J. Fang, Y. Ye, D. Yu, H. Su, D. Xian, D. Qin, J. Wang

 

Journal: PNAS

 

Convection (thunderstorm) develops rapidly within hours and is highly destructive, posing a significant challenge for nowcasting and resulting in substantial losses to infrastructure and society. After the emergence of AI-based methods, convection nowcasting has experienced rapid advancements, with its performance surpassing that of physics-based numerical weather prediction and other conventional approaches. However, the lead time and coverage of it still leave much to be desired and hardly meet the needs of disaster emergency response. Here, we propose a deep diffusion model for satellite data (DDMS) to establish an AI-based convection nowcasting system. Specifically, DDMS employs diffusion processes to effectively simulate complicated spatiotemporal evolution patterns of convective clouds, achieving more accurate forecasts of convective growth and dissipation over longer lead times. Additionally, it combines geostationary satellite brightness temperature data and domain knowledge from meteorological experts, thereby achieving planetary-scale forecast coverage. During long-term tests and objective validation based on the FengYun-4A satellite, our system achieves effective convection nowcasting up to 4 h, with broad coverage (about 20,000,000 km2), remarkable accuracy, and high resolution (15 min; 4 km). Its performance reaches a new height in convection nowcasting compared to the existing models. In terms of application, our system is highly transferable with the potential to collaborate with multiple satellites for global convection nowcasting. Furthermore, our results highlight the remarkable capabilities of diffusion models in convective clouds forecasting, as well as the significant value of geostationary satellite data when empowered by AI technologies.

Marine heatwaves (MHWs) are periods of anomalously warm sea temperatures that are becoming increasingly recognised as ocean stressors. Globally, MHWs have impacted marine ecosystems, with significant socioeconomic implications for coastal communities and industries. The unprecedented MHW that occurred in the waters surrounding the UK and Ireland in summer 2023 highlighted a crucial gap in our understanding of the region-specific characteristics of MHWs and their impacts on marine ecosystems, the services they underpin, the blue economy and society. Using diverse expert opinion, we propose 40 priority questions for interdisciplinary research in the UK that must urgently be addressed to prepare for future risks and potential opportunities associated with MHWs. The targeted questions are listed under a broad range of themes. Recommendations to policy makers and those influencing the strategic direction and allocation of funding and resources are also suggested to assist decision-makers towards evidence-based action and guide funding streams.

Ocean transport and vertical mixing

connect Greenland's macroalgae to deep ocean carbon sinks

Authors: D. F. Carlson, N. Suzuki, R. Carrasco, K. Filbee-Dexter, L. C. Gillard, P. G. Myers, A. M. Queirós, J. Assis, C. M. Duarte, M. Sejr, D. Krause-Jensen

 

Journal: Science of The Total Environment

 

Macroalgal carbon export estimates make assumptions about lateral transport away from the coast and vertical export to deep ocean sinks. Yet, few studies have resolved these pathways. This paper tests lateral surface transport and vertical export assumptions using the Southwest Greenland continental shelf and the Labrador Sea as a testbed. Macroalgae grow on Greenland's rocky shoreline and previous studies have documented oceanographic connectivity between coastal and offshore regions. This study analyzed 1380 Sentinel-2 satellite images to find 7973 patches of floating macroalgae on the SW Greenland shelf and in the Labrador Sea, providing evidence of their presence on the shelf and offshore waters. Since satellite imagery provides a snapshot of macroalgal positions at a given time, 305 surface drifter trajectories and a Lagrangian particle tracking model (LPTM) are used to quantify residence times and transport pathways. The average drifter-derived surface residence times on the SW Greenland shelf and the Labrador Sea are 12.1 days and 63.6 days, respectively. Applying results from studies of macroalgal longevity, the drifter-derived residence times suggest that macroalgae can remain intact during their transit of the shelf, allowing them to sink in deeper water offshore. The LPTM traced the origins and pathways of selected patches in June 2018. To explore vertical export mechanisms, a Large Eddy Simulation revealed that deep convection can transport buoyant macroalgae to depths where their gas vesicles implode, expediting sinking. These interdisciplinary findings indicate that Greenland's macroalgal ecosystems can supply detrital carbon to the adjacent shelf and open ocean and highlight the importance of testing key transport assumptions used to estimate macroalgal contributions to carbon sequestration.

The ocean is essential for humanity1,2,3. Yet, inequity in ocean-based activities is widespread and accelerating4,5,6,7,8. Addressing this requires governance approaches that can systematically measure equity and track progress9. Here we present the Ocean Equity Index (OEI)—a framework for assessing and improving equity in ocean initiatives, projects and policies. We apply the index, which scores twelve criteria, to case studies at local, national and global scales. We show that the OEI can generate structured data to support evidence-based decision-making across ocean sectors and scales. As a theoretically robust and widely applicable tool, the OEI can guide the design of more equitable ocean initiatives, projects or policies, ensuring better outcomes for coastal people and marine ecosystems.
