“…For example TDN:TDP may be preferred over DIN:DIP for calculating N:P ratios as total concentrations provide analytically robust estimates of bioavailable N and P, and TDN is considered the analogue of TDP and its use (Zirino et al, 2016;Lomas et al, 2010). Other studies have used DIN:DIP ratios (Kim et al, 2003;Murrell et al, 2007;Wang et al, 2015). Here significantly lower N:P ratios were observed when only inorganic nutrients were used to calculate N:P ratios.…”

“…The dinoflagellate component of spring bloom biomass in the Gulf of Finland increased from 10% to 70% over a decade (Klais et al, 2011). Riverine inputs of dissolved inorganic P to the Changjiang Estuary increased 574% from 1970 to 2013 (Wang et al, 2014). Oxygen and more than 50 fish species returned to the anoxic and fishless Thames Estuary within a decade after advanced sewage treatment was implemented (Andrews & Rickard, 1980).…”

Time series of environmental measurements are essential for detecting, measuring and understanding changes in the Earth system and its biological communities. Observational series have accumulated over the past 2-5 decades from measurements across the world's estuaries, bays, lagoons, inland seas and shelf waters influenced by runoff. We synthesize information contained in these time series to develop a global view of changes occurring in marine systems influenced by connectivity to land. Our review is organized around four themes: (i) human activities as drivers of change; (ii) variability of the climate system as a driver of change; (iii) successes, disappointments and challenges of managing change at the sea-land interface; and (iv) discoveries made from observations over time. Multidecadal time series reveal that many of the world's estuarine-coastal ecosystems are in a continuing state of change, and the pace of change is faster than we could have imagined a decade ago. Some have been transformed into novel ecosystems with habitats, biogeochemistry and biological communities outside the natural range of variability. Change takes many forms including linear and nonlinear trends, abrupt state changes and oscillations. The challenge of managing change is daunting in the coastal zone where diverse human pressures are concentrated and intersect with different responses to climate variability over land and over ocean basins. The pace of change in estuarine-coastal ecosystems will likely accelerate as the human population and economies continue to grow and as global climate change accelerates. Wise stewardship of the resources upon which we depend is critically dependent upon a continuing flow of information from observations to measure, understand and anticipate future changes along the world's coastlines.

“…The MARINA results show increasing trends in nutrient export by Chinese rivers since 1970 (Section 7.4.2). These increasing trends agree with various modeling (e.g., Bao et al 2006;Liu et al 2008a;Qu & Kroeze 2010;Ti et al 2012;Xing & Zhu 2002;Yan et al 2010) and empirical studies (e.g., Li et al 2014b;Li et al 2007;Sun et al 2013a;Tao et al 2010;Wang et al 2015). o…”

“…Other studies are mostly for large individual rivers and nutrients. Examples include studies for the Yellow Tong et al 2016), Yangtze Li et al 2011b;Li et al 2011c;Powers et al 2016;Sun et al 2013a;Sun et al 2013b;Wang et al 2015;Yan et al 2010;Yu et al 2011) and Pearl (Huang et al 2003;Yin et al 2004). In general, these studies confirm an increase in fluxes of dissolved nutrients by rivers since the 1970s, except for Powers et al (2016) who showed a declining trend in P export by the Yangtze since 1970.…”
