Abstract The ca. 300 Ma Fengcheng Formation in the Junggar Basin of NW China is
reported to develop a rare alkaline lake (soda lake) in this study, based on an expanded …

Nitrogen is an essential nutrient for all life on Earth and it acts as a major control on
biological productivity in the modern ocean. Accurate reconstructions of the evolution of life …

The stable isotope composition of animal tissues can provide intrinsic tags to study the
foraging and migratory ecology of predators in the open ocean. Chapter 13 (this volume) …

We recently reported that decomposition (as a carbon source) of organic matter (OM) is the
dominant process in coastal waters after typhoons, which is contrary to phytoplankton …

Life and the sustainable growth of socioeconomic sectors such as agriculture and industry
depend on groundwater, particularly in arid and semi-arid regions where surface water …

Nitrogen isotopes are an important tool for evaluating past biogeochemical cycling from the
paleoceanographic record. However, bulk sedimentary nitrogen isotope ratios, which can be …

Stable carbon and nitrogen isotope analyses of human and animal tissues have become an
important means of studying both anthropogenic and natural food webs in aquatic …

Abstract During the Marinoan Ice Age (ca. 654–635 Ma), one of the 'Snowball Earth'events
in the Cryogenian Period, continental icesheets reached the tropical oceans. Oceanic …

Water column depth profiles along the North Pacific margin from Point Conception to the tip
of Baja California indicate elevation of nitrate (NO3−) 15N/14N and 18O/16O associated …

Nitrogen isotope compositions in sedimentary rocks (d 15 N sed) are routinely used for
reconstructing Cenozoic N-biogeochemical cycling and are also being increasingly applied …
