Over 100 nautical miles off the coast of China in the Yellow Sea, a huge octagonal structure rests in the water. This is no new-look oil rig. It’s Dee.
On the golden coastline of eastern China's Shandong province lies the country's "Golden City" Laizhou. Boasting rich gold reserves, the city's economy is underpinned by the gold mining industry, but like many other mines worldwide, it used to be plagued by workplace safety risks.
China’s oil and gas player CNOOC Limited has kicked off production from an oilfield development project in the Bohai Sea. This is the third project, which the Chinese giant has brought on stream offshore China this month.
Nutrient reduction in catchments is an important strategy to mitigate coastal eutrophication. The responses of ecosystems to nutrient reduction on a decadal scale can help us to understand the effects of environmental restoration. Here, the cascading trophic interactions of mesozooplankton and phytoplankton in Laizhou Bay were analyzed to examine the effects of river nutrient reductions during 2004–2014. The results showed that the diversity of the mesozooplankton assemblages and the proportion of higher trophic species increased after nutrient reductions, and mesozooplankton abundance showed obvious decrease annual trends. A significantly positive correlation between mesozooplankton and phytoplankton abundance was identified in August, and mesozooplankton abundance was mainly influenced by phytoplankton abundance in August while by microzooplankton and jellyfish in May when the phytoplankton abundance was lower. This result indicates that the recovery of mesozooplankton assemblages
