In this study we examine potential higher- and lowertrophic-level effects of ocean acidification with the potential to affect ecosystem-wide dynamics by emulating two effects that have been demonstrated to occur in multiple independent studies. These effects that are examined are a decrease in micro ...

Radiocarbon dating of late Quaternary sediments: reservoir

As a result, in most regions marine samples yield radiocarbon ages substantially older than those yielded by terrestrial samples. The 14C ages of marine foss ...

Effects of global warming on oceans
Global warming can affect sea levels, coastlines, ocean acidification, ocean currents, seawater, sea surface temperatures, tides, the sea floor, weather, and trigger several changes in ocean bio-geochemistry; all of these affect the functioning of a society.
