This article should be disambiguated. F-ratio in optics can also mean the ratio of the focal length of a telescope to its aperture. And there's also an F-ratio distribution in statistics. Jason Quinn 17:22, 25 September 2006 (UTC)
This was a very nice job. I added a little bit of text describing the distinction between the export and microbial loops and referencing the papers of Laws et al. (2000) and Dunne et al. (2005). -- Agnana 20:00, 13 November 2006 (UTC)
Dear authors of this page. Congratulations for your efforts. I suggest to add something to the 'overview' section. Beyond the logistic problems involved in deploying sediment traps (as the texts explains), sediment traps are known to experience a number of bias: currents may affect the efficiency of the collection process; zooplantkon may enter actively the traps biasing the measurment of the gravitative flux; .. many things may happen. And even if you are able to limit the biases and believe that the trap is measuring relaibly the settling flux of particles, then still you have to consider that such a flux is not strictly vertical but three-dimensional. Sediment traps are at present the best available tools to estimate the downward flux of organic matter derived from photsynthesis in the upper ocean...but they present still many drawbacks. If you need references try for example:
Thomas, S., and P.V.Ridd (2004). Review of methods to measure short time scale sediment accumulation. Marine Geology. 207, 95-114. Buesseler, K.O.; et al. (2007).

Wikipedia has done it again. You've explained the f-ratio to each other elegantly. Now, what is the f-ratio? JohndanR ( talk) 18:33, 19 October 2014 (UTC)
There is a move discussion in progress on Talk:F-ratio (disambiguation) which affects this page. Please participate on that page and not in this talk page section. Thank you. — RMCD bot 22:35, 23 August 2021 (UTC)
