Halong ("descending dragon" in Vietnamese) is a 1553 km² bay in the norther coast of Vietnam sown with about two-thousand limestone isles, and a UNESCO World Heritage Site.
Halong Bay harbors traditional fisheries and aquaculture settings, but is also subject to intense touristic and commercial marine traffic, wastewater spills and great inputs of black carbon.
In November 2018 we sampled in thisstudied the role of marine microbes in degrading black carbon particles in Halong Bay.
Our colleague Thuoc Van Chu from IMER always saves the day: he's not only our interpreter but also the best connoisseur of Halong Bay.
Xavier Mari investigates the role of black carbon in the marine biological carbon pump. During our experiments in Halong Bay, he sweated hard to sample enough surface microlayer volume!
