Blue carbon and the role of coastal sea in carbon sequestration

Blue carbon is the carbon stored in coastal and open ocean ecosystems, including those habitats, species, and processes that facilitate the uptake of atmospheric carbon into the ocean and transport that carbon into sediments or deep waters. Coastal wetlands (mangrove, seagrass and salt marsh) are among the most productive ecosystems that sequester and store great quantities of blue carbon. In this three-day workshop participants will: 1) Conduct a timely review of the historical trend and current status of the blue carbon in coastal wetland in global estuarine and coastal ecosystems. 2) Revisit the role of coastal ocean in carbon cycle, especially the fate of the river input, with the newest advance in the research on the subject. 3) Estimate the upper and lower constraint of the capacity of the coastal seas (both regional and local scales) in absorbing anthropogenic CO2, including the efficiency and capacity of the “biological pump” (including the "microbial carbon pump") in a warming scenario. 4) Identify possible mitigation measures for Hong Kong's marine territory, such as green aquaculture and wetland restoration, to help our government to reach its goal of carbon neutrality.

  • Professor Nianzhi Jiao Academician, Xiamen University Prof. JIAO Nianzhi from Xiamen University proposed the concept “microbial carbon pump (MCP)” illustrating that these tiny marine inhabitants are also producers of refractory dissolved organic carbon, a persistent form of matter which can be stored in the ocean for thousands of years and thus constitute an ideal carbon pool. https://english.cas.cn/bcas/2013_3/201411/P020141121530449009344.pdf
  • Professor Minhan Dai Academician, Xiamen University Biography Minhan Dai is a Chair Professor of Marine Biogeochemistry at Xiamen University, China (http://mel.xmu.edu.cn/staff.asp?tid=13) where he serves as the Director of the State Key Laboratory of Marine Environmental Science. Minhan Dai’s research interests include ocean biogeochemistry of carbon and nutrients and geochemistry of radioactive elements in surface and ground waters. Born in 1965 and raised in Hangzhou, Minhan Dai earned his B.S. degree from Xiamen University and his Ph.D. from Université Pierre & Marie Curie, France in 1995. After a Doherty Foundation Postdoctoral Fellowship at Woods Hole Oceanographic Institution (WHOI), he took a faculty position at Xiamen University in 1998. He was elected as an Academician of the Chinese Academy of Sciences in 2017. Minhan Dai has published over 150 papers in leading international journals (http://www.researcherid.com/rid/G-3343-2010). He is a leading PI of a “973” project funded through National Basic Research Program of China on “Carbon cycling in China Seas - budget, controls and ocean acidification” (CHOICE-C) which is at her second phase funded through 2019. He has served on many national and international committees. The above bio is copied from https://www.asiaoceania.org/aogs2019/public.asp?page=mhd_abs_bio.htm
  • Dr. Richard A. Feely Senior Scientist, NOAA Pacific Marine Environmental Laboratory https://www.pmel.noaa.gov/co2/story/Richard++A.+Feely,+Ph.D.
  • Professor David Karl Victor and Peggy Brandstrom Pavel Professor of Microbial Oceanography and Director of the Daniel K. Inouye Center for Microbial Oceanography: Research and Education (C-MORE), University of Hawaii David Karl is the Victor and Peggy Brandstrom Pavel Professor of Microbial Oceanography and Director of the Daniel K. Inouye Center for Microbial Oceanography: Research and Education (C-MORE) at the University of Hawai’i. In spring of 1973, Karl participated in his first oceanographic research expedition to the Cariaco Basin aboard the RV Eastward. Since that time Karl has spent more than 1,000 days conducting research at sea including 23 expeditions to Antarctica. In 1988 he co-founded the Hawaii Ocean Time-series (HOT) program that has conducted sustained physical, biogeochemical and microbial measurements and experiments at Station ALOHA on approximately monthly intervals for the past 25 years. In 2006, he led a team of scientists in the establishment of a new NSF-supported Science and Technology Center at the University of Hawai’i. C-MORE conducts collaborative research on marine microorganisms from genomes to biomes, and has a vital training mission to help prepare the next generation of microbial oceanographers. Karl has received several awards and honors including the G. Evelyn Hutchinson Medal from the American Society for Limnology and Oceanography, the Henry Bryant Bigelow Medal from Woods Hole Oceanographic Institution, the Alexander Agassiz Medal from the U.S. National Academy of Sciences and an honorary D.Sc. degree from the University of Chicago. He is a Fellow of the American Geophysical Union and the American Academy of Microbiology, and a member of the U.S. National Academy of Sciences.
  • Professor Nicolas Gruber Professor, ETH Zürich Research area Dr. Gruber's research interests are the study of biogeochemical cycles on regional to global scales and on timescales from months to millennia, with a particular focus on the interaction of these cycles with Earth's climate system. His goal is to better understand the physical, chemical and biological processes that control these cycles and to be able to make predictions for the future, especially with regard to the potential feedbacks between the global carbon cycle and a changing climate. His primary research tools are the interpretation and analysis of observational data coupled with the use of models ranging in complexity from simple box models to general circulation models. Curriculum Vitae Nicolas Gruber has been Full Professor of Environmental Physics at the Department of Environmental Sciences at ETH Zurich since July 2006. Dr. Gruber was born in Peru in 1968, and moved to Switzerland at the age of 6. After his Matura in 1989, he was among the first students to enter the new Environmental Sciences degree program at ETH Zurich. As part of his undergraduate studies, he spent one year at the Scripps Institution of Oceanography, La Jolla, California, where he worked with the late Charles D. Keeling, sparking his interests in the human perturbation of the global carbon cycle. After earning his diploma degree in 1993, Dr. Gruber went to the University of Bern for his Ph.D. studies, which he completed in 1997. He then worked for three years as a postdoctoral researcher at Princeton University. In 2000, he joined the Department of Atmospheric and Oceanic Sciences and the Institute of Geophysics and Planetary Physics at the University of California, Los Angeles, first as an assistant professor, and from 2005 until 2007 as a tenured associate professor. In 2006, he was appointed as a full professor at ETH Zurich. Dr. Gruber has written over 170 peer-​reviewed publications, with more than 20 having appeared in Science, Nature, and the offsprings of Nature.  Dr. Gruber, together with Jorge Sarmiento from Princeton University, is author of the textbook "Ocean Biogeochemical Dynamics" that has become a standard text in the field. In recognition of his outstanding contribution to Marine Sciences, Dr. Gruber received the Rosenstiel Award from the Rosenstiel School of Marine and Atmospheric Sciences of the University of Miami in 2004. In 2012 he was elected fellow of the American Geophysical Union. He is member of several international research boards, is member of the governing board of Climate-​KIC, and serves as review editor for the Science Magazine.   More information can be found at https://c2sm.ethz.ch/the-center/people/person-detail.html?persid=45838
