Dr. Hans Paerl received the International Cooperation Award from the governor of the Jaingsu Province for his work teaching at Hohai University and for the research done on Lake Taihu and other Chinese lake projects. The pictures below include Dr. Paerl and his colleagues Guangwei Zhu and XuHai (left to right) from the Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Nanjing. Also see Dr. Paerl with the African exchange students at Hohai University, where he was teaching an aquatic ecology course last May.
Dr. Hans Paerl is back in China collaborating with colleagues from Hohai University and has been busy with bio-assays and water sampling on Lake Taihu! Check out some of the photos and stay tuned for more about his field work there!
For two and a half decades, ModMon has provided valuable information on water quality and habitat conditions in the Neuse River Estuary and Pamlico Sound. These data are crucial for evaluating how conditions are changing in response to human and climatic pressures. ModMon has also served as a platform to support research projects aimed at figuring out how estuaries work from ecological, geological, physical, and biogeochemical perspectives.
Conditions on 4 June 2019 were pretty typical for this time of year. Salinities ranged from zero above New Bern to a maximum of about 15 in the bottom waters near the mouth. Stratification was not particularly intense except at station 160 which was influenced by saltier bottom water likely from the Intracoastal Waterway. Hypoxic conditions occurred throughout most of the length of the estuary but were confined to a thin, ~1 m thick, layer near the bottom. A zone of high DO, high pH, and high chlorophyll a was observed at station 30 near New Bern. Microscopic examination of surface waters from station 30 revealed a high concentration of cryptophytes that are generally good food for higher trophic levels, and don’t cause problems.
