These dissolution and precipitation reactions can modify the porosity and permeability of porous media, but predictive capabilities of such impacts are limited.Mineral reactions occur on reactive surfaces given perturbations from equilibrium. Mineral dissolution occurs in undersaturated conditions and oversaturated conditions favor mineral precipitation. Porosity increases with mineral dissolution and decreases with mineral precipitation such that the overall porosity can typically be effectively predicted. Permeability evolution, however, cannot be as easily predicted. Previous literature has observed that an increase in porosity can result in an increase (

“…The mineralogy and chemistry of the two units is nearly identical, with quartz, plagioclase (oligoclase An 27 ), microcline, and biotite as major minerals (Cole, 1977;Mast et al, 1990;Mast, 1992). Magnetite, ilmenite, garnet, epidote, apatite, monazite, zircon, orthopyroxene, calcite, and pyrite occur as minor minerals (Cole, 1977;Mast et al, 1990;Mast, 1992;Price et al, 2013Price et al, , 2017Price et al, , 2020.…”

“…As with N, phosphorus (P 5+ , often reported as orthophosphate PO 4 3− ) may contribute to algal blooms (e.g., Bostrom and Petterson, 1982;Smith et al, 1999;Baken et al, 2016;Krumina et al, 2016). The bedrock within the LVW contains the mineral apatite (Ca 5 (PO 4 ) 3 (OH,F,Cl)), and is dissolving sufficiently rapidly to have released PO 4 3− at a flux of ∼50 mol ha −1 year −1 from 1984-2008 (Price et al, 2013(Price et al, , 2020. This value is ∼20× greater than the global average reported from models by Hartmann et al (2014).…”

Climatic controls on phosphorus concentrations in The Loch, Loch Vale Watershed, Rocky Mountain National Park, Colorado, USA since the last glacial maximum

The alpine–subalpine Loch Vale watershed (LVW) of Colorado, USA, has relatively high natural lithogenic P5+ fluxes to surface waters. For 1992–2018, the largest number of stream samples with P5+ concentrations ([P5+]) above detection limits occurred in 2008, corresponding with the highest frost-cracking intensity (FCI). Therefore, relatively cold winters and warm summers with a comparatively low mean annual temperature partly influence stream [P5+]. Sediment cores were collected from The Loch, an outlet lake of the LVW. Iron-, Al-, and Mn-oxide-bound phosphorus (adsorbed and authigenic phosphates; NP) serves as a proxy measurement for paleolake [P5+]. The highest NP in the core occurred during the cold and dry Allerød interstade. The lowest NP concentrations in the core occurred during climatically very wet periods in the Late Pleistocene and Early Holocene. Therefore, [P5+] are highest with relatively cold winters followed by relatively warm summers, relatively low mean annual temperatures, and relatively little rainfall and/or cryospheric melting. Currently the LVW is experiencing warming and melting of the permanent cryosphere with a rapidly declining FCI since 2008. This has the potential to dramatically decrease [P5+] in surface water ecosystems of the LVW, reducing biological productivity, enhancing P-limitation, and increasing ecosystem reliance on aeolian P5+.

“…In the case of pH, Ostrofsky et al [16] mentioned that the formations of P-CO 3 and P-Ca are favored in basic environments at high temperatures in sediments rich in organic matter and nitrogen. However, Price et al [17] noted a high remobilization of these P fractions at pH less than 5. According to N'Da et al [3] and März et al [18], this situation is mainly due to the reduction of the negative surfaces of sediments simultaneously with the competition of Ca 2+ with the other major cations (K + , Na + , Mg + , etc.)…”

This study focused on the effects of the climate change and the recent modification of Vridi channel on the mobility and distribution of phosphorus (P) in its superficial sediments. To best estimate this fact, the annual mobility and distribution of P were followed and compared before and after this development during two different annual periods, marked differently by the climate change effects. The first annual period has covered the period from April 2014 to March 2015 and this channel presented its former hydromorphology, with hydroclimatic conditions very close to that normal of Abidjan district. The second period annual has covered the period from October 2018 to September 2019 and this channel presented its current hydromorphology and, characterized by a rainfall drop and high ambient air temperatures compared to that normal of Abidjan district. A monthly sampling has been done at 5 cm below the surface sediment in this channel during each annual period. The mobility and distribution of P was assessed in the superficial sediments of this channel according two sequential extraction protocols: the modified Van Eck method and the modified Olsen method. Total phosphorus was assessed according AFNOR NF X31-147. The total phosphorus contents and all P fractions contents of these superficial sediments assessed by these two sequential methods and obtained over the period from April 2014 to March 2015 are higher than those determined over the period from October 2018 to September 2019. Thus, the recent development of this estuary, with as a corollary the modification of the physical and chemical characteristics of its superficial sediments, would have had the effect of clearing P towards the Atlantic Ocean and/or accelerating its sedimentation; hence the reduction of eutrophication risk of this aquatic ecosystem.
