The consortium Megacity’s fingerprint in Chinese southern marginal seas: Investigation of pollutant fingerprints and dispersal aims to study the marine environmental conditions in an area spanning from the northern shelf in proximity to Pearl River of the South China Sea towards the deep sea, to enhance our understanding of the effects of growing anthropogenic pressure in a highly dynamic marine ecosystem governed by natural variability ranging on space scales from small to mesoscale and time from daily to decadal. The area is an excellent natural laboratory to study the exchange processes between the land and the ocean (Pearl River), the variability of physical forcing (monsoon, circulation), the drastically increasing anthropogenic stress (nutrients/eutrophication, organic contaminants, microplastic, antibiotics, mercury) following the development of a Megacity within the area Guangzhou-Hong Kong. We are aiming to improving our understanding of the complex interactions between land, the coastal ocean and the open ocean and their resulting alterations due to effects of climate variability and anthropogenic stressors in a highly sensitive ecosystem. Our results will help to quantify the marine N, P, C cycles, allow the quantification and distribution of anthropogenic contamination as well as the degree of time-space variability of natural oceanic processes. This consortiums with 4 German and 5 Chinese partners work is closely linked to the complementary twin project Megacity’s fingerprint in Chinese eastern marginal seas: Investigation of pollutant fingerprints and dispersal coordinated by Dr. Pohlmann (Univ. HH), regionally focussed on Bohai Sea, Yellow Sea and the Yangtse River. Samples will be gained and exchanged between the twin projects aiming at an overview of the regional distribution of several substances within the partitions water, suspended matter and sediment. Intercalibration exercises regarding UV-filters and joint modelling efforts are part of the activities, going hand in hand with joint meetings, cruises and publications for participants of both consortia. Our consortium project contributes to the BMBF program marine research (Meeresforschung, PTJ) and is rooted in the WTZ-China initiative, dating back to 1986. Our activities are a continuation of the bilateral projects PECAI and BEIBU, both relevant to the programs Forschung für die Nachhaltigkeit (FONA) and System Erde.
