Bridging Borders for Cleaner Estuaries: A Journey with the GEM Programme

Notes from the Editorial Team:

We are delighted to feature Jefferson Escobar Yamashiro's remarkable journey and contributions to the Global Estuaries Monitoring (GEM) Programme in this article. Jefferson's dedication as an environmental chemist and his collaboration with the State Key Laboratory of Marine Pollution (SKLMP) in Hong Kong exemplify the spirit of international cooperation in protecting our estuaries and oceans. His experiences shed light on the importance of monitoring estuary health and the global efforts towards a cleaner future.


We extend our gratitude to Jefferson for sharing his insights and experiences. His story serves as a reminder that the fight against contaminants transcends borders and requires collective action. We hope that his journey inspires others to join in the pursuit of safeguarding our precious marine ecosystems.


Let's explore the remarkable synergy and achievements that have ignited between Jefferson and our dedicated GEM team during this inspiring month of June.


Hello everyone! I am Jefferson Escobar Yamashiro, an environmental chemist and a PhD student from Brazil. It is with great pleasure that I share my transformative experience collaborating with the State Key Laboratory of Marine Pollution (SKLMP) in Hong Kong as part of the Global Estuaries Monitoring (GEM) Programme.


My journey began with collecting water samples in my home state. Little did I know that this initial step would lead me to immerse myself in the fascinating world of sample extractions and analyses at the City University of Hong Kong (CityUHK). Through my involvement in the GEM Programme, I have witnessed firsthand the collective efforts aimed at monitoring and understanding the health of estuaries worldwide.


During my time at the SKLMP, I had the privilege of working alongside an amazing team comprising Mr. Yutong Zhang, Ms. Xitong Fu, Mr. Ming Liu, Ms. Demilade Adedipe, and Dr. Chong Chen. Their expertise and support have been instrumental in shaping my research endeavors. I extend my heartfelt gratitude to them for their guidance and collaboration.

As my internship at the SKLMP draws to a close, I am reminded of the profound truth that contaminants know no borders. Our fight for cleaner and safer oceans is a global endeavor, driven by researchers, scientists, and environmentalists around the world. Every water sample collected, every chromatogram analyzed, and every research effort undertaken contributes to our shared mission.


Looking ahead, I am excited to continue my work within the GEM research network, a collective effort spanning multiple institutions passionate about building a comprehensive understanding of estuary contaminants. This collaborative approach holds immense potential for creating a global picture of estuary health and identifying effective strategies for preserving these vital ecosystems.

I would like to express my deepest gratitude to all those who made my internship at the CityUHK possible, particularly Prof. Kenneth Mei Yee Leung, the esteemed Principal Investigator of the GEM Programme. I am also grateful to my supervisor in Brazil, Prof. Cíntia de Oliveira, for providing me with this invaluable opportunity.


Together, let us embrace the knowledge that our actions and dedication can make a positive impact on the health of our oceans. By bridging borders and fostering international collaborations, we can pave the way towards a cleaner and more sustainable future.


Thank you for your unwavering support and commitment to preserving our precious marine ecosystems.


Best regards,

Jefferson Escobar Yamashiro
