Then, taking into account that a known amount of sediment could have been removed by other processes (plate tectonics), they have used these three numbers to estimate how long it would have taken to deposit that amount of sediment. They then, using the time that geologists believe that these oceans were filling, compare to see if the assumption for sediments depositing over deep time is reasonable. \u00a0This type of claim involves two sides.\u00a0 It involves the numbers that are used to support the claim. \u00a0It also involves understanding if these numbers are valid for this use.<\/p>\n<p>First, let\u2019s look at the input numbers.<\/p>\n<p><span style=\"color: #0839a3;\"><strong>1.

(Snelling 2009)\u00a0 In 2009, he reported that \u201c<em>the average rate from a dozen studies is 24,108 million metric tons per year<\/em>.\u201d\u00a0 He says that these do not include sediment carried along the base of rivers as bedload.\u00a0 In 2012, he reduced his number to \u201cabout 20 billion tons of dirt and rock debris\u201d.\u00a0\u00a0 One key paper that he cites is Milliman and Syvitski, (1992).\u00a0 This quote from them should serve as a warning regarding basing too much on the quantitative estimates of sediment discharge.<\/p>\n<p><em>\u201cWhat Is the Sediment Flux to the Sea? This question really has two parts: how much sediment is carried by rivers, and how much escapes the present-day land\/estuarine environment?

It does tell us that the numbers quoted by Snelling are larger than newer estimates, though this alone would not really change the conclusion.<\/p>\n<p>If we are looking to see the rate of sediment supplied to the sea over geologic time, the present rates are not representative.\u00a0 We will talk about more reasons for this later, but at this point, A key point to the study by Dedkov and Gusarov (2006) was to examine the human impact on sediments supplied to the ocean.

How much sediment is removed by other processes?<\/strong><\/span><\/p>\n<p>So far, we have less sediment flowing into the ocean and we have more sediment in the oceans.\u00a0 The effect of these, less input and more output, suggests that the sediment accumulation would have taken longer to form.\u00a0\u00a0 Are there other ways that could remove sediment and thus increase the amount of time required?\u00a0 One key component of plate tectonics is that along plates that are colliding, sediment is caught up with subducting plates and lost to the crust. \u00a0Snelling reports, \u201cOnly 1 billion tons (5%) are removed by tectonic plates\u201d (Snelling 2012). \u00a0Again, several estimates have been made. Stern (2002) observed this:<\/p>\n<blockquote>\n<p><em>\u201cEstimates of the mass of sediments subducted annually range from about 1 10<sup>15<\/sup> g\/yr\u00a0 [Veizer and Jansen, 1985; Hay et al., 1988] to 3\u20134 10<sup>15<\/sup> g\/yr [von Huene and Scholl, 1991]\u201d<\/em>\u00a0 (Stern 2002)<\/p>\n<\/blockquote>\n<p>It is worth noting that Hay, et al (1988) considered their estimate of <em>1 10<sup>15<\/sup> g\/yr<\/em> a minimum number. While the first numbers quoted formed the basis for the estimate quoted by Snelling, what if the later number by Von Huene and Scholl (1991) is valid?\u00a0 Consider this scenario, with the units converted.\u00a0 If we take the total particulates presented by Cohen, et al. (2022), reduce them by 2.6 times as proposed by Dedkov and Gusarov (2006), this would mean a total load of 6.8 billion metric tons supplied by rivers each year.\u00a0 The plate tectonics loss determined by Von Huene and Scholl (1991) of up to 4 billion metric tons per year, then, taking into account the increased sediment thickness when the continental shelves are included, it begins to look like the amount of sediment is almost balanced by the amount lost by plate subduction.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #0839a3;\"><strong>4. How long do geologists believe the ocean floor sediment took to be deposited?<\/strong><\/span><\/p>\n<p>Last May, my wife and I took a driving vacation including a short excursion into Washington, D.C.\u00a0 We didn\u2019t go straight there by any means and it took much more time than would have been required to go directly there.\u00a0 Imagine that a friend asks \u201chow long did it take you to get to the capitol?\u00a0 I could have answered truthfully that it took me 68 years to get there. Such an answer would have been factual, but probably not helpful to the questioner. Given that we went approximately 2000 miles to get there, our average rate of travel would have been really slow considering the 68 year time.\u00a0 We would have been travelling at a gruesomely slow rate of 0.003 miles per hour, roughly a literal snail\u2019s pace.\u00a0 We actually spent 12 days traveling, including a bit of unscheduled layover for car repair. This equates to about 7 miles per hour and given that we weren\u2019t actually driving for much of the time, that is a bit more representative.<\/p>\n<p>Calculating the time it took to deposit the sediment in the ocean is a bit like this as well.\u00a0 If YEC want to say that the deep time explanations for the filling of the oceans do not work, then they need to use the actual time durations accepted my modern geology. \u00a0Dr. Snelling, as quoted earlier referred to 3 billion years of ocean filling.\u00a0 In a since it is true that geologists believe that oceans have been filling for that time, just as it took me 68 years to get to Washington, D.C.\u00a0 On the other hand, geologists believe that the current oceans have been filling for much less time.\u00a0 One could consider the current configuration of the continents and the sediment filling the oceans to have been taking place perhaps since the beginning of the Jurassic, approximately 200 million years ago.\u00a0 Olson, et al., (2016) writing on \u201cVariation of ocean sediment thickness with crustal age\u201d used roughly the beginning of the Cretaceous period, 150 million years ago as the period of time to be investigated.\u00a0 That tells us that if we compare these numbers to Snelling\u2019s figure of 3 billion years ago, geologists believe that much less time was involved (93 \u2013 95% less) in the deposition of the sediments on the seafloor.\u00a0 This fact is recognized by Snelling (2009) and Tomkins and Clarey (2021), but it is more dramatic to misrepresent modern geology by speaking of 3 billion years.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h2><span style=\"color: #0839a3;\">Other Factors<\/span><\/h2>\n<p>The factors discussed so far can easily account for the modern sediment supplied to the oceans.\u00a0 But wait\u2026 there\u2019s more (a bit like the adds for wonderful devices sold on TV).\u00a0\u00a0 <strong>First, <\/strong>remember that geologists believe that the Earth\u2019s history was dynamic.\u00a0 We cannot look at the rivers of today and assume that what we see today was constant over the last 150 million years.\u00a0 This becomes important in several ways. First, at times in the past, oceans covered much of today\u2019s continents. Thus rivers in those periods were dumping sediments into the seas, but the sediments that were laid down are on today\u2019s continents and were not included in the sediment thicknesses used for YEC claims.\u00a0 <strong>Figure 3<\/strong> shows a paleogeographic map of what we believe the continents looked like 94 million years ago. (Scotese, n.d.).\u00a0 Notice that large portions of the modern continents were covered by seas. Rivers dumped sediments into these ancient seas but it does not appear in the YEC calculations. When I was exploring for gas in South Texas, I wanted to study outcrop analogs for the Cenozoic wave-dominated deltas that formed the sands that were our targets.\u00a0 I went on a great field trip to Utah to study Cretaceous wave-dominated deltas there. They were sands fed by rivers to the sea. How significant are these onshore deposits?\u00a0 <strong>Figure 4<\/strong> shows the total sedimentary thickness maps for North America and the surrounding oceans. (Mooney and Kaban 2010)\u00a0 Much of that sediment is less than 150 million years old and would then add to the sediment record of ancient river deposition.<\/p>\n<p>In assuming that geologists view the present as same as the past, the YEC interpretations are strawman arguments in another way as well.\u00a0 Geologists recognize that over the last 3 billion years many changes have taken place that would have dramatically impacted the amount of sediment shed to the ocean.\u00a0 Over the last 150 million years the overall climate trends have varied.\u00a0 If we zoom into the last 450,000 years, it has varied very sharply. (<strong>Figure 5<\/strong>)\u00a0 Colder periods are expected to have higher rates of sediment washed to the seas.\u00a0 Colder wet periods had more rainfall.\u00a0 Large continental glaciers pushed continents lower, but when the glaciers retreated, the continents rebounded as we measure them doing today in North America and the Nordic regions.\u00a0 In fact, the amount of sediment delivered to the sea over the recent thousands of years still feels the effect of glaciation to increase rates over earlier rates and then we have the added impact of human that increased them even more.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/jesusinhistoryandscience.com\/wp-content\/uploads\/2025\/01\/Scotese-Cretaceous.png?resize=1024%2C646&#038;ssl=1\" width=\"1024\" height=\"646\" alt=\"\" class=\"wp-image-3812 aligncenter size-large\" srcset=\"https:\/\/jesusinhistoryandscience.com\/wp-content\/uploads\/2025\/01\/Scotese-Cretaceous-980x619.png 980w, https:\/\/jesusinhistoryandscience.com\/wp-content\/uploads\/2025\/01\/Scotese-Cretaceous-480x303.png 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/p>\n<p style=\"text-align: center;\"><span style=\"color: #0c71c3;\"><strong>Figure <\/strong><strong>4<\/strong><strong>.<\/strong> Where did ancient rivers dump their sediment?

This claim is not\u00a0 isolated to Paul Humber or Andrew Snelling.\u00a0 In general, the reports seem to just parrot earlier claims without anyone looking at later work or critically assessing the details.\u00a0<\/p>\n<p>They overestimate the sediment supplied to the oceans today and neglect to compensate for the impact of humans on current rates. They assume that the current rates should be extrapolated back over hundreds of millions or billions of years despite abundant evidence that for much of the last 150 million years of deep time, less sediment would have been delivered to the oceans.\u00a0 Much of that which reached the seas would be found on today\u2019s continents and this is\u00a0 not included.<\/p>\n<p>The average thickness on the ocean floor is reported to be 400 meters. We have seen that this neglects to include the major deposits by rivers along the continental shelf.\u00a0 If included this would have more than doubled the average thickness. Thick deposits on the abyssal floor should not be expected because sources from the continents just would never have reached them.\u00a0 No one proposes a way to estimate how much sediment is shed each year from the continental shelf to the lower slope or basin floor. Ultimately this alone invalidates the YEC proposals.<\/p>\n<p>Their assumption of how much sediment on the ocean floor exits by way of plate tectonics and plate subduction is likely low.\u00a0 It is reasonable to conclude that the sediment input from rivers fits well the amount of sediment on the seafloor.\u00a0 The balance of inputs with that exiting by subduction is what one should expect from a system designed by a highly intelligent benevolent creator preparing a planet for mankind.<\/p>\n<p>&nbsp;<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p style=\"text-align: center;\"><span style=\"color: #0839a3;\"><strong>References Cited<\/strong>\u00a0<\/span><\/p>\n<p>Cohen, Sagy, Jaia Syvitski, Thomas Ashley, Roderick Lammers, Balazs Fekete, and Hong-Yi Li. 2022. \u201cSpatial Trends and Drivers of Bedload and Suspended Sediment Fluxes in Global Rivers.\u201d <em>Water Resources Research<\/em> 58 (6): e2021WR031583. <a href=\"https:\/\/doi.org\/10.1029\/2021WR031583\">https:\/\/doi.org\/10.1029\/2021WR031583\u00a0<\/a><\/p>\n<p>Dedkov, A P, and A V Gusarov. 2006. \u201cSuspended Sediment Yield from Continents into the World Ocean: Spatial and Temporal Changeability.\u201d In <em>Sediment Dynamics and the Hydromorphology of Fluvial Systems<\/em>, 3\u201311.
