“…Studies involving marine radiocarbon measurements and/or modeling have been performed in different basins, with distinct time scales and different types of samples. There have been many independent studies of oceanic paleoventilation and calculation of reservoir ages, ultimately assisting in the reconstruction of past climatic events (Andree et al, 1986;Bard, 1988;Björck et al, 2003;Bolton et al, 2016;Broecker, 1991;Broecker et al, 1988Broecker et al, , 2004Burr et al, 2015;Butzin et al, 2005;Carré et al, 2016;Cook & Keigwin, 2015;de la Fuente et al, 2015;Douarin et al, 2016;Druffel & Suess, 1983;Druffel et al, 1998;Hall et al, 2010;Hua et al, 2015;Hughen et al, 1998;Ikehara et al, 2011;Kennett et al, 1997;Kovanen & Easterbrook, 2002;Komugabe-Dixson et al, 2016;Marchitto et al, 2007;Ritz et al, 2008;Sarnthein et al, 2007;Shen et al, 2004;Stern & Lisiecki, 2013;Wündsch et al, 2016, to cite a few).

When a carbon reservoir has a lower radiocarbon content than the atmosphere, this is referred to as a reservoir effect. This is expressed as an offset between the radiocarbon ages of samples from the two reservoirs at a single point in time. The marine reservoir effect (MRE) has been a major concern in the radiocarbon community, as it introduces an additional source of error that is often difficult to accurately quantify. For this reason, researchers are often reluctant to date marine material where they have another option. The influence of this phenomenon makes the study of the MRE important for a broad range of applications. The advent of Accelerator Mass Spectrometry (AMS) has reduced sample size requirements and increased measurement precision, in turn increasing the number of studies seeking to measure marine samples. These studies rely on overcoming the influence of the MRE on marine radiocarbon dates through the worldwide quantification of the local parameter ΔR, that is, the local variation from the global average MRE. Furthermore, the strong dependence on ocean dynamics makes the MRE a useful indicator for changes in oceanic circulation, carbon exchange between reservoirs, and the fate of atmospheric CO2, all of which impact Earth's climate. This article explores data from the http://calib.qub.ac.uk/marine/ and reviews the place of natural radiocarbon in oceanic records, focusing on key questions (e.g., changes in ocean dynamics) that have been answered by MRE studies and on their application to different subjects.
