title: Salt marsh soil carbon content, loss on ignition, dry bulk density, carbon stocks and carbon accumulation rates for Clayoquot Sound, British Columbia, Canada

description: The goal of this project was to provide the first estimates of blue carbon stocks and carbon accumulation rates in the high and low marsh zones of salt marshes from the Pacific Coast of Canada, within the Clayoquot Sound UNESCO Biosphere Reserve and Pacific Rim National Park Reserve on the Pacific Coast of Canada. Thirty-four sediment cores were collected from seven salt marshes during summer (June-September) 2016. Sediment cores were collected using a simple percussion coring technique in which a length of two-inch (57 mm) diameter, PVC vacuum tubing fitted with a plastic core catcher (AMS Inc.) was hammered into the ground until the depth of refusal. At the GBK location, a steel sledge corer (AMS Inc.) was used to extract four cores before mechanical problems required switching to the simpler percussion method.The purpose of collecting these cores was to determine soil carbon and sediment properties necessary for calculating carbon stocks and accumulation rates in different marsh zones. At each core site, marsh zone (high vs low) was determined using vegetation types surrounding the core site. Coring spots were considered low marsh if the species Triglochin maritima, Salicornia spp., Fucus ssp. or Ditschilis spicata were present, and high marsh if it included Plantago maritima, Deschampsia caespitosa, Grindelia integrifolia, Potentilla anserina, Lysimachia maritima, or Eleocharis ssp. The majority percent cover of high or low marsh species was used to determine a "high" or "low" marsh designation. On all 34 cores, we measured core compaction, dry bulk density, % loss-on-ignition, and % organic carbon (using an elemental analyzer, on select number of samples). Compaction was measured as length of core penetration divided by the length of core recovered. From these measured parameters, we estimated % organic carbon (using a regression equation between % organic carbon and %LOI), soil carbon density, and carbon stocks measured to (a) the depth of the basal peat layer, (b) a depth of 20 cm, and (c) to the depth of the 30-year horizon (estimated in the 8 cores where 210Pb analysis was completed).

title: Salt marsh soil lead-210 and dating for Clayoquot Sound, British Columbia, Canada

description: The goal of this project was to provide the first estimates of blue carbon stocks and carbon accumulation rates in the high and low marsh zones of salt marshes from the Pacific Coast of Canada, within the Clayoquot Sound UNESCO Biosphere Reserve and Pacific Rim National Park Reserve on the Pacific Coast of Canada. Sediment cores were collected from seven salt marshes during summer (June-September) 2016. The cores were collected using a simple percussion coring technique in which a length of two-inch (57 mm) diameter, PVC vacuum tubing fitted with a plastic core catcher (AMS Inc.) was hammered into the ground until the depth of refusal. At the GBK location, a steel sledge corer (AMS Inc.) was used to extract four cores before mechanical problems required switching to the simple percussion method.Radioisotope (210Pb and 226Ra) measurements were conducted on eight cores (four from the high marsh zone and four from the low marsh zone) from marshes CBE, CRF, GBK, and TMF, to create age models for estimating carbon accumulation rates. Activities of 210Pb were determined by alpha spectrometry through its granddaughter 210Po, assumed in secular equilibrium. The atmospheric or excess 210Pb (210Pbxs) fraction used to derive the age-depth model was determined as the difference between the total 210Pb activity and its parent nuclide 226Ra activity. 226Ra activities were determined by α-spectrometry at Flett Research using calibrated geometries in a glass vessel, Spectech UCS 30 Alpha Scintillation Spectrometer purged with helium, and sealed for at least 11 days. Samples were sealed and stored for two hours before counting to ensure secular equilibrium of 226Ra daughters. 226Ra was determined through counting 222Rn activity for 60,000 seconds (Minimum Detectable Activity (MDA) = 0.0167 Bq kg-1). Sediment chronologies were estimated using the Constant Flux: Constant Sedimentation (CF:CS) model, which assumes a constant atmospheric deposition of 210Pb to the marsh surface and a constant mass accumulation rate (MAR, [g cm-2 yr-1]). Under these assumptions, the MAR was obtained from the slope [cm2 g-1] of the linear best-fit line of the relationship between the natural log of the excess 210Pb activity against the cumulative mass [g cm-2] using MAR (g cm-2 y-1) = 0.0311 (yr-1)/slope (cm2 g-1), where 0.0311 yr-1 is the radioactive decay constant of 210Pb. We emphasize that we have estimated 210Pb-derived accumulation rates in terms of cumulative mass (g cm-2) instead of depth, to avoid issues of compaction associated with the coring process.

title: Organic carbon, calcium carbonate contents, mass accumulation rate, burial efficiency, and paleoproductivity record from a sediment core SK-313 GC01 southeastern Arabian Sea

description: Variations in the paleoproductivity during the last 14.4 kyr have been studied using organic carbon (OC), calcium carbonate (CaCO3) contents and their mass accumulation rate and burial efficiency, in a 14C-dated sediment core (SK 313 GC-01; 4.82-m) from the southeastern Arabian Sea. The core was sub-sampled at 1-cm intervals for the top 1 m and 2-cm intervals for the rest of the core. All subsamples were oven-dried at 40°C and finely powdered in an agate mortar with a pestle. CaCO3 content was determined by Ethylene Diamine Tetra-Acetic acid (EDTA) titration using Patton & Reader as an indicator (Shapiro and Brannock, 1962, doi:10.3133/b1144A). The OC content was determined by chromic acid digestion and subsequent titration with ferrous ammonium sulfate as described in Gaudette et al. (1974, doi:10.1306/74D729D7-2B21-11D7-8648000102C1865D). We note that paleoproductivity was the highest during the Bølling–Allerød warm event; a step-wise decreased productivity during the Younger Dryas cold period, the lowest productivity during the early Holocene, and increased and stabilized productivity during the mid-late Holocene interval.
description: Accumulation rate (MAR) of OC and CaCO3 (g/m²/a) was calculated using the following formula: OC (CaCO3) = (OC (CaCO3)×DBD×LSR)/100.Paleoproductivity (g/cm²/a) was estimated using the following formula by Stein (1986, hdl:10013/epic.14450): Paleoproductivity (PP) = 5.31 [OC (DBD)]0.71× LSR0.07 × WD0.45.Burial efficiency (BE, %) of OC was estimated using the following formula by Bhushan et al. (2001, doi:10.1016/S0025-3227(01)00179-7): BE (%) = [(Burial Flux)/Productivity]×100.

title: Organic carbon, humus and pH values in cryogenic soils near Batagay megaslump, northern Yakutia (2019)

description: Cryogenic soils near Batagay megaslump, located in the Verkhoyansk region, northern Yakutia were investigated in detail in August-September 2019. Soil samples from the Batagay megaslump were analyzed for organic carbon and humic substances. The pH was determined in soil extracts. On the slope to the Batagay megaslump, a soil catena was studied. It included the near-summit surface of the Kirgilyakh slope, the middle part of the slope, as well as the bord of the Batagai megaslump. The soil cover in the area of the Batagay ravine is represented by various types of soils formed on permafrost rocks, mainly Cryosols Gleyic, found in various landscape conditions, and Podzols Entic are also sporadically distributed in the area. On alluvial deposits in the valley of the Batagaika river Podzols Haplic are formed. Leptosols Lithic are confined to the elevation of the relief with bedrock located close to the surface. The main processes typical for soils in the Batagay megaslump area are: cryogenic structuring, organic matter accumulation, Al-Fe-humus and gleiing processes. Above the permafrost horizon a local minimum of pH values was noted both in Podsols Entic and in Cryosols Gleyic.
description: The content of organic carbon and humus in soil samples was carried out in the laboratory of the Ecological and Geochemical Center at the Faculty of Geography of Lomonosov Moscow State University under the leadership of E.V. Terskaya. The measurements were carried out according to the method of I.V. Tyurin, which is based on an oxidation of organic carbon in soils with an excess of Cr⁶⁺-ion.The hydrogen index (pH) was measured in 30 samples taken from the genetic horizons of soils near the Batagay megaslump in August 2019. Water extracts of soils were made by mixing pre-dried, pounded with a porcelain pestle in a porcelain mortar and sifted through a sieve (with a pore diameter of 1 mm) of a sample with distilled water. Mixing was carried out in a ratio of 1:25 for samples from peat horizons O and in a ratio of 1:5 for samples from all the other soil horizons.Soil horizons were named according to the nomenclature by Shishov et al. (2004):O: Organic horizon less than 10 cm thick comprises peat and detritus;pir: Any horizon that contains coal. Stands for “pyrogenic”;┴ : Any permafrost horizon;E: Stands for “eluvial”. Analogue of albic horizon. The albic horizon is defined as a diagnostic subsurface horizon that is comprised of primary sand and silt particles that are light-colored because they lack iron oxide coatings;BF: Illuvial horizon, that is enriched by iron oxydes;BHF: Illuvial horizon, that is enriched by iron oxydes and humus;f: Any horizon with distinct signs of iron accumulation;p: Rock inclusions;CRM: Stands for “cryo-metamorphic”. Mineral horizon with granular structure caused by cryogenic processes;C: Loose parent material
