WMU PhD Candidate Publishes in Nature.com
A PhD candidate at the World Maritime University’s WMU-Sasakawa Global Ocean Institute, Ms Kristie Alleyne, has published as lead author some of her research findings in Scientific Reports Nature.com, which is one the world's most cited multidisciplinary academic journals. Ms Alleyne is a member of the WMU-Sasakawa Global Ocean Institute’s “Closing the Circle: Marine Debris, Sargassum and Marine Spatial Planning” Programme, exploring challenges and potential solutions to the sargassum and the plastic pollution threat in the Eastern Caribbean with the support of generous funding from The Nippon Foundation and in partnership with CERMES at the University of the West Indies (UWI), Barbados.
As part of her PhD project, Ms Alleyne conducted spatiotemporal analyses of sargassum influx events in Barbados. In her recent publication in the Scientific Reports of Nature Journal, she and her co-authors (Professor Francis Neat at WMU, Professor Hazel Oxenford at UWI-CERMES, Dr. Henri Valles at UWI and Dr. Donald Johnson at the University of Southern Mississippi) quantified the species and morphotype composition of sargassum strandings in Barbados and tested if this was related to separate oceanic origins and routes traveled using a backtracking algorithm. Interestingly, they found significant seasonal variation in the relative abundance of three morphotypes that could be traced to two distinct easterly sub-origins and/or transport pathways. The first sub-origin/transport pathway lies around 15° N and travels directly E–W across the Atlantic, the second sub-origin/transport pathway lies south of 10° N and takes a more meandering route coming close to the coast of South America.
These research findings are significant because of the mass proliferation of pelagic sargassum in the Tropical Atlantic. This in turn has resulted in major ecological and socioeconomic impacts on regional fisheries and tourism industries in the Eastern Caribbean. The unprecedented occurrence of sargassum in the Caribbean has been tracked to a ‘new’ bloom region known as the North Equatorial Recirculation Region (NERR) encompassing the area between the South Equatorial Current and the North Equatorial Counter Current and extending from Africa to South America. The vast biomass of sargassum presents a plethora of management challenges when it washes ashore but also represents significant commercial opportunities. However one challenge to the valorisation of this new resource is the uncertainty in the supply of pelagic sargassum and morphotypes. Sargassum arriving in Barbados consists of two major species (Sargassum fluitans and S. natans), with three commonly occurring morphotypes (S. natans I, S. natans VIII and S. flitans III). Oceanic mixing tends to blend the morphotypes together making it difficult to determine if there are regions of the NERR that favor bloom and growth of the distinct types. Research on the variability in morphotype composition is thus necessary to better understand factors responsible for the continued proliferation of pelagic sargassum and turn a current threat into opportunities.
The identification of these two sub-origins/transport pathways points to resolvability of the complex problem of blooms; why now, why here, what are the dominant parameters that influence growth and mortality? Moreover, the findings of this study are relevant to the developing sargassum industry by providing insights into the potential causes of variation in morphotype composition arriving in the Caribbean. Information on morphotype composition will be important to managers and decision-makers and the interventions they make at different times of the year as the region continues to tackle the complex challenges associated with influx events.
Ms Alleyne points out that scientific forecasts are predicting moderate to severe sargassum influx events in the upcoming months, thus, there are certainly many challenges on the horizon. Nevertheless, she believes that valorisation of pelagic sargassum presents an opportunity to minimize the negative impacts associated with sargassum strandings; however, contamination with plastic and heavy metals presents concerns. In this regard, her research shows that understanding the origins of pelagic sargassum is only one piece of this very complex problem. “The ‘Circle’ is far from closed but the WMU-Sasakawa Global Ocean Institute (GOI) together with CERMES from the University of the West Indies, Barbados are working arduously to understand and address valorization challenges, specifically as it relates to levels of arsenic, in hopes of transforming the Golden Tides into sustainable valorization opportunities”, said PhD Candidate Kristie Alleyne. ‘ We have however identified one important piece of the equation that must be resolved if we are to address the impacts of sargassum but much remains to be done research wise’.
In congratulating Ms Alleyne on publishing her research findings in the world-leading journal Scientific Reports Nature.Com, Professor Ronán Long, Director of the WMU-GOI, says that the close working partnership with UWI-CERMES and the support of The Nippon Foundation are both vital for undertaking applied research on what has become a major hazard for coastal communities in the Eastern Caribbean. He is confident that the results can be applied by Barbados and several other Small Island Developing States and further afield in their battle against the ecological and health crisis caused by the mass proliferation of pelagic sargassum due to climate change and other anthropogenic impacts on the marine environment.
About the Closing the Circle Programme
The "Closing the Circle" Programme: Marine Debris, Sargassum and Marine Spatial Planning, is hosted at the WMU-Sasakawa Global Ocean Institute with the generous support of The Nippon Foundation . The programme team consists of the Project Principal Investigators, a Research Fellow and 4 PhD candidates whose research on respective projects explore challenges and advance potential solutions to marine debris, sargassum threats and marine spatial planning (MSP) in Small Island Developing States (SIDS) with a particular focus on the Eastern Caribbean region. The Region is facing a mounting problem from vast beach strandings of the normally oceanic seaweed Sargassum. The combination of marine debris and Sargassum seaweed is resulting in an untold ecological impact and socioeconomic hardship for these SIDS that are highly dependent on tourism. Marine spatial planning (MSP) has emerged as a new approach to holistically plan and manage ocean space and resources. Learn more about the Closing the Circle programme here.
My decision to enroll in the doctoral program at WMU was heavily influenced by my prior experience as a Master's student at the institution. Initially introduced to me as a preeminent global institution for maritime education, WMU's stellar reputation was further substantiated by the exceptional quality of education I received during my Master’s studies. This experience became a compelling factor in my determination to return to WMU as a doctoral student. Recognizing the synergies between my research aspirations and the institutional offerings at WMU, I concluded that continuing my educational journey at this esteemed institution was not only beneficial but also aligned perfectly with my academic and professional goals.
My research explored the theoretical foundations of governance, placing a particular emphasis on maritime governance. Going beyond mere theoretical frameworks, the study conducted a comprehensive examination of a crucial aspect within maritime governance—specifically, the implementation of International Maritime Organization (IMO) instruments, exploring the contextual factors that affect the implementation process. Applying the grounded theory methodology, the research aimed to understand these theoretical underpinnings, as well as firmly anchor insights in the practical context of maritime governance; unveiling the intricacies and challenges associated with the effective implementation of IMO instruments in the maritime domain. The selection of this topic was motivated by a personal interest that was cultivated during my Master’s studies in maritime law and policy. Furthermore, it was driven by the recognition of a scarcity of scientific research on this specific topic. This gap in the existing body of knowledge served as a catalyst for my exploration, underscoring the significance of contributing valuable insights to an area of maritime governance that has been relatively underrepresented in scholarly research.
Undoubtedly, a highlight of my educational journey at WMU was the opportunity to forge connections with influential change-makers and thought leaders hailing from every corner of the globe. This invaluable chance to engage with individuals on an international scale has not only enabled me to expand my global network but has also served as a conduit for immersing myself in the rich tapestry of diverse cultures. Through these global interactions, I've gained a profound understanding of different perspectives, traditions, and approaches, contributing significantly to my personal and academic growth. This experience goes beyond mere networking and has also played a pivotal role in fostering stronger connections within the Caribbean region from which I hail.
Embarking on my professional path, my foremost aim is to establish myself as an authority in the field of maritime governance. I aspire to leave a significant and enduring mark on the global maritime landscape. Beyond the academic sphere, my drive is fuelled by a passionate interest in pursuing diverse opportunities within the maritime domain and the broader educational sector and contributing significantly to positive transformations in the global maritime sector.
I was primarily attracted to WMU for its prestigious standing as a global leader in maritime education and research. The institution's emphasis on sustainability and its diverse international student body were particularly appealing. My research, which focuses on the transition of ports toward low and near-zero carbon emissions, perfectly aligns with WMU's dedication to sustainable maritime practices. This common vision made WMU the ideal choice for advancing my academic and professional aspirations in the maritime industry.
A significant highlight of my time at WMU has been the invaluable opportunity to collaborate with a diverse group of experts and peers from various corners of the globe. This international environment has broadened my perspective on maritime issues and fostered a rich exchange of ideas. It has been a rewarding experience to engage in discussions, share insights, and work collectively toward innovative solutions to complex maritime challenges.

My plans involve actively contributing to the sustainable transformation of the industry by focusing on the implementation of greener and more efficient port operations. I aim to play a part in fostering a cleaner and more sustainable future for ports and shipping on a global scale.
The fact that the World Maritime University (WMU) is a global ocean institute of excellence piqued my initial interest. However, my decision to join the WMU team was solidified with the announcement of the Closing the Circle Scholarship. This incredible opportunity allowed me to study with a diverse team of ocean leaders and facilitated important research for the Wider Caribbean Region.
My research focused on spatiotemporal analyses of climate change driven sargassum blooms in the Tropical Atlantic. Since the onset of mass sargassum blooms in 2011, Caribbean countries have experienced multiscale negative socioeconomic and environmental impacts. Evidence suggests that influx events are driven by ocean eutrophication and climate change and are likely to continue into the foreseeable future leaving countries with no choice but to adapt to their new reality. Against this backdrop, the research assessed changes in the biodiversity, morphotype composition and arsenic content of incoming sargassum rafts and identified sustainable solutions/management interventions.
It is said that you cannot achieve anything entirely by yourself, this is especially true of a PhD. Thankfully, in a place so far from home, I was fortunate to have a team of strong, dependable, caring and intelligent Caribbean women to complete this journey with me. Sharing this incredible milestone with them has been without a doubt the most impactful and memorable part of my PhD journey at WMU.
After dedicating the last 3 years of my life to achieving one goal, I must admit that I've had a slight case of tunnel vision. Ideally I would like to continue in the world of research and academia, however, my unknown future is in the hands of the all-knowing God.
The Closing The Circle Programme: Marine Debris and Sargassum in the Eastern Caribbean drew me into the World Maritime University (WMU) as it was specifically aligned and tailored to my research interests and experiences and offered the flexibility for me to expand on ongoing research on the subject matter that I had already been working on. A highlight of studying at WMU has been building relationships within the university and maturing in my faith and academics.
My research assessed governance barriers facing Caribbean Small Island Developing States (SIDS) in their ability to equitably participate in the development of the global plastics treaty. I chose this topic because Caribbean SIDS are disproportionately affected by mass influxes of marine plastics to their coastlines and lack various capacity needs to address the issue. After graduation, I'll be continuing work through my non-profit organization, Bahamas Plastic Movement, and will employ aspects of my PhD research towards addressing the plastic pollution crisis in the Caribbean.
I was attracted to the World Maritime University (WMU) in Sweden simply due to the opportunity to research the transboundary challenges of marine litter in the Eastern Caribbean. My specific research focus on the Windward Islands allowed me to contribute solutions to a region I am deeply connected to.
Marine litter poses significant threats to Caribbean Small Island Developing States, affecting marine ecosystems, tourism, fisheries and other local economies, and the health of the communities. My choice to focus on this crisis was driven by the urgency to shed light on its magnitude, propose sustainable solutions, and advocate for more global efforts in addressing this pressing environmental issue.
Studying at WMU provided a multifaceted experience that extended beyond just academics, and there are two highlights worth mentioning to represent this. One, the amazing opportunity for intercultural exchange. I had the privilege of collaborating with researchers and experts from around the globe. This diverse gathering not only facilitated a unique learning environment but also opened doors to share varied perspectives. This exchange was instrumental to my research and learning process and enriched my career path. I found myself collaborating with and even speaking alongside some of the most respected experts in the field on renowned panels. Two, is a particularly exhilarating experience which was representing the university in the UN interagency games in 2022. I was honored to be a part of the first women's team from WMU. Against expectations, I managed to place third in my backstroke category, even though it was my first time participating in competitive swimming. Our team's dedication and hard work culminated in a podium finish, as we secured third place overall.
Post-graduation, my professional trajectory, initially aimed singularly at university teaching in Grenada, has evolved to include curricula development on marine conservation topics at various educational levels, aspiring to inspire the next generation. While my zeal for academia remains steadfast, my aspirations have broadened to encompass policy advocacy. My research, highlighting the striking linkages between marine litter and the overarching climate crisis, has fortified my resolve to employ these insights toward tangible change. Now, as I pivot towards a more policy-oriented role, I aim to work collaboratively with policymakers. My focus will be on underlining the Caribbean's unique environmental challenges, advocating for climate compensation, and concurrently influencing educational approaches on marine issues.
I was attracted to the World Maritime University by the “Closing the Circle Programme”, the aims of which matched my interests, experience and expertise. The programme was co-designed with Eastern Caribbean leaders and focused on marine environmental challenges with a global reach but a regional focus. This was an important element for me as it provided an opportunity to contribute to research which had the potential to deliver meaningful research impact beyond academia. WMU has a warm and welcoming atmosphere. The staff and faculty are experienced and very helpful. It has also been an extremely gratifying experience to collaborate with and learn from my colleagues from all over the world.
My research focused on abandoned, lost and otherwise discarded fishing gear (ALDFG), also called derelict fishing gear, in the context of Eastern Caribbean small-scale fisheries. The main aim of the thesis was to understand the barriers to effective governance of the challenge, with a view to identifying mechanisms for overcoming these. The research was undertaken through a three-pronged approach focused first on identifying the nature of the challenge in the Eastern Caribbean, followed by outlining challenges to governance and finally proposing recommendations for improvement.
My immediate plans after graduation are to return to Antigua and to my previous job at the Fisheries Division where I can, hopefully, continue to work on researching this topic. In the long term, my hope is to transition to academia.
I chose the World Maritime University for my PhD studies in Maritime Affairs because of several reasons, including its academic reputation and strong postgraduate degrees in maritime and ocean science-related programmes, a range of international modules, and the diverse group of students and faculty members. WMU is in Sweden, one of the EU countries with the best gender equality ranking worldwide. As a woman in marine science who faced several challenges in the industry, I was mainly attracted to the Empowering Women for the United Nations Decade of Ocean Science for Sustainable Development programme offered at the university. This unique programme aims to promote gender equality and women’s empowerment in ocean science to increase women’s participation in ocean science and advance the sustainable management and governance of ocean spaces and maritime activities at all levels through capacity building.
My research topic focused on evaluating gender equality in ocean science for Sustainable development in Kenya. The primary aim of this study was to examine gender equality in ocean science institutions in Kenya, using the existing institutional gender policies, gender-disaggregated data of students and staff, the experiences and barriers faced by students and staff in this field as well as the good practices that the institutions already have to promote gender equality. The issue of gender equality and women’s empowerment are generally relevant for ocean governance because they bring diverse perspectives, skills and solutions to management and sustainability. I chose this research topic to understand the root causes of gender inequalities and persistent biases in the ocean science sector to make invisible voices and contributions of women in ocean science visible and to ensure women or marginalized groups are included in decision-making and policy-making processes as the primary users of marine resources.
I have had a fantastic journey and an incredible and rewarding experience at WMU. Studying here came with many blessings and was one of the best decisions I have ever made. First, my supervisors were resourceful, outstanding and very supportive, who dedicated their time to mentor and guide my research work. Their guidance, advice, motivation, kindness, understanding and support were instrumental and helped me achieve my academic goals to reach where I am today. Second, the university has a strong family bond, is well-organized, and embraces teamwork, and I received immense support from the GOI and WMU secretariat. Also, I managed to interact with many students from different nationalities, exchanged ideas and discovered/learned a lot of things from the various cultures, especially during the annual celebration of the WMU International Day, made new friends from around the world, expanded my network and immensely improved my global view.
After graduation, I plan to expand my network and find a job that includes both academic and practice-oriented research to continue advocating for gender equality in ocean science. Also, I plan to develop a policy brief for the ocean science institutions in Kenya as a guide for promoting gender equality in ocean science both in higher education and employing agencies. My natural science background will also open doors to explore and work in freshwater and marine environments.
It had always been exciting for me to pursue research on maritime law affairs in a well-known maritime institute. To that end, the World Maritime University (WMU) appeared the best choice. Undoubtedly, the academic community and cordial non-academic staff have made WMU not only a great university for studying but also a pleasant place for living.
My research interest lies in the recognition of the effects of foreign judicial sales of ships, more precisely, the recognition of the purchaser’s title obtained in a judicial sale. This is essential to the realization of claims on a ship, which to a large degree depends on a sale obtaining a market price of the ship. Without the prospect that a judicial sale will finalize with a title binding everyone, potential bidders would probably not offer such a price. Against this backdrop, an international convention has been concluded to bridge the gap in the protection for purchasers in judicial sales. Considering the importance of the role shipping plays in international trade as well as the high value of ships as assets, I find this topic worth exploring.
A highlight of studying at WMU was the celebration dinner after my defense. The cheering card on the table, the tasty food, and most importantly the people who had supported me all the way sitting around me that very day, made an unforgettable and joyful end to the four-years’ journey. I still and will always remember that touching moment.
My plan now is to continue my journey in the legal world. After graduation, I will be a postdoc and teacher in law at a high education institution, sharing and using what I have learned at WMU.
