Abstract:

Arctic coastal erosion mobilizes large quantities of permafrost organic matter to the Arctic Ocean, where it may be decomposed, releasing carbon dioxide. To quantify the biodegradability of this eroding material, we designed an aerobic bottle incubation experiment to measure CO2 production from coastal soils/sediments submerged in seawater. Seasonally thawed active layer soils and permafrost were sampled near Drew Point along the Alaska Beaufort Sea coast. Cores were taken from three surface geomorphic classifications common in this area: primary surface that has not been reworked by thaw-lake cycles, a young drained lake basin, and an ancient drained lake basin. Core subsamples were chosen to represent three distinct horizons present in eroding bluffs at Drew Point: seasonally thawed active layer soils near the tundra surface, Holocene-age terrestrial soils and/or lake sediments, and late-Pleistocene age relict marine sediments. Soil/sediment subsamples were mixed with Beaufort Sea surface water and incubated in triplicate at 4C and 16C for 40 days. In addition, a subset of soil/sediment samples were incubated with and without seawater at 16C for 40 days. The data reported here summarizes the results of the incubation experiment for each soil sample: cumulative CO2-C production over 40 days normalized to dry weight and to organic carbon content (OC), average rate of CO2 production normalized to dry weight and to TOC, and the percent of OC remineralized over 40 days.

Description:

Sample collection

Cores were collected near Drew Point from April 10th-19th, 2018 using two coring systems. Near-surface cores (upper 4 to 6 m) were acquired using a SIPRE corer (7.5 cm diameter) and cores at depth were acquired using a JIPRO corer (7.5 cm diameter). To capture variations in near-surface permafrost characteristics, we sampled each of the three dominant geomorphic terrain units present in the Drew Point region: primary surface material that has not been reworked by thermokarst lake formation and drainage, an ancient drained thermokarst lake basin (DTLB) (Hinkel et al. 2003; Jones et al., 2012), and a young DTLB (Jones et al., 2012). Each permafrost core spanned from the tundra surface to below local mean sea level. Cores were collected in air temperatures between -10 and -20 degrees C. They were packed into coolers for transport back to Utqiagvik, Alaska and then flown frozen to the University of Alaska in Fairbanks where the cores were stored in a -20 degrees C freezer room prior to shipping them frozen to Sandia National Laboratory in Albuquerque, NM for processing.

At Sandia National Laboratory, sections from the frozen cores were cut using a band saw that was cleaned with Milli-Q water and ethanol after each use. Core material was then thawed in acid-washed glass beakers at room temperature for subsampling. Thawed soil/sediment was placed in Whirl-packs and frozen for bulk soil/sediment organic carbon and nitrogen content, stable carbon and radiocarbon analysis, and experimental work.

Core sections for this experimental work were chosen to represent similar depths within three distinct soil/sediment horizons within each core: the seasonally thawed "active layer", Holocene age terrestrial/lacustrine derived permafrost, and permafrost composed of relict, Pleistocene-aged marine sediment. This relict marine permafrost is located above and below modern day sea level in Drew Point bluffs. Additional information about core collection, sampling, and geochemical characteristics can be found in Bristol et al. 2021. Physical and geochemical data from these cores is also published on Environmental Data Initiative (https://doi.org/10.6073/pasta/cc4d53a91ed873765224fcb6d09f5eb7).

Seawater used for the incubation experiment was collected from Beaufort Sea surface waters near Barter Island during August 2018. Seawater was filtered using pre-combusted Whatman GF/F (0.7 um) filters and transported frozen to the University of Texas Marine Science Institute. The seawater had a salinity of 31 and a DOC concentration of 1.2 mg C L^-1.

Incubation experiment

We simulated the decomposition of eroding coastal soils by incubating active layer and permafrost samples from Drew Point in seawater in aerobic conditions at two temperatures (4 and 16 degrees C) in the dark for 40 days. As a comparison, we also incubated a subset of samples within and without seawater at 16 degrees C. To facilitate comparisons with other study areas, we generally followed experimental methods outlined by Tanski et al. (2019, 2021). Briefly, homogenized core sections were thawed at 4 degrees C and triplicate subsamples of 20 g wet weight were placed in precombusted ~120 mL glass serum bottles. Subsamples for wet:dry weight ratios were also taken at this step. For the seawater treatments, 30 mL of filtered seawater was added to each serum bottle. As a control, bottles containing only seawater were also incubated. The pH of the mixtures and seawater controls were measured before sealing the bottles with rubber septa. Then, the headspace of each bottle was flushed using a tank of compressed atmospheric air (480 ppm CO₂). This same tank of atmospheric air was used throughout all experimental work.

Headspace samples were collected at 5, 10, 20, 30, and 40 days for bottles incubated at 4 degrees C, and at 1, 3, 5, 10, 20, 30, and 40 days for bottles incubated at 16 degrees C. Before sampling, each bottle was over-pressurized by adding 12 mL of gas from the tank of compressed atmospheric air using a gas tight syringe. Bottles were gently shaken to allow equilibration. After a few minutes, bottle headspace was sampled by transferring 12 mL of gas to 5.9 mL pre-evacuated Exetainer vials. After headspace sampling, septa were removed to measure the pH of the slurries and seawater controls. Then, bottles were resealed and flushed with atmospheric air using the tank of compressed atmospheric air for 6 minutes with an approximate flushing rate of 900 mL min^-1. Experimental work was conducted at the University of Texas Marine Science Institute. Exetainers vials were promptly shipped via ground transport to Florida State University to measure CO₂ concentrations.

Geochemical analyses

Measurements of total organic carbon (OC) and total nitrogen (TN) content, stable carbon isotope ratios (δ¹³C) and radiocarbon (¹⁴C) analyses of bulk soils/sediments were conducted at the Woods Hole Oceanographic Institution (WHOI), National Ocean Sciences Accelerator Mass Spectrometer (NOSAMS) facility. Bulk samples were dried at 60 degrees C then finely ground using a mortar and pestle. Ground samples went through a vapor fumigation acid/base treatment step to remove inorganic carbon. This step involved placing samples in a vacuum-sealed desiccator in a drying oven (60 degrees C) with a beaker of concentrated HCl for 24 hours. Samples were then removed and placed in another vacuum-sealed desiccator with a dish of NaOH pellets, and again stored in a drying oven at 60 degrees C for another 24 hours. This latter step neutralized excess HCl. Samples were combusted using an Elementar el Vario Cube C/N analyzer. TOC and TN (% by weight) were quantified during this step. The resulting CO₂ was transferred to a vacuum line and cryogenically purified. The purified CO₂ gas samples were converted to graphite targets by reducing CO₂ with an iron catalyst under 1 atm H2 at 550 degrees C. Targets were subsequently analyzed for stable and radiocarbon isotopes (δ¹³C as ‰ and ¹⁴C as fraction modern carbon). All Δ¹⁴C data (in ‰) were corrected for isotopic fractionation using measured δ¹³C values that were quantified during the ¹⁴C-AMS procedure. We measured δ¹³C in these samples separately on a VG Prism Stable Mass Spectrometer at NOSAMS. Δ¹⁴C and radiocarbon age were determined from percent modern carbon using the year of sample analysis according to Stuiver and Polach (1977).

CO₂ concentrations in headspace gas samples were measured at Florida State University. Pressurized exetainer vials were interfaced to a 1 mL gas sampling loop on a Shimadzu 8A gas chromatograph equipped with a methanizer and calibrated against Airgas standards. The GC had a carbosphere column and was operated at 140 degrees C.

CO2 production calculations

Headspace CO₂-C was calculated using measured headspace volumes and CO₂ concentrations, accounting for changes in pressure and concentration when bottles were over pressurized with atmospheric gas before sampling. Headspace pressure within the bottles was assumed to be 1 atm before over pressurizing. Dissolved CO₂ was calculated for seawater treatments using the solubility of CO₂ at the incubation temperature and seawater salinity (Weiss, 1974). Dissolved inorganic carbon (DIC; i.e., dissolved CO₂, bicarbonate, and carbonate) was calculated using the calculated dissolved CO₂ concentration, measured pH, and volume of seawater. When calculating CO₂-C production, we also accounted for the inorganic carbon that remained in the headspace and seawater after flushing, using atmospheric air CO₂ concentrations and pH at each timepoint. DIC calculations were performed using constants from Lueker et al. (2000), Dickson and Riley (1979) and Dickson (1990) using the 'seacarb' package in R v.3.3.0. (Gattuso et al., 2021).

CO₂-C production from decomposition was calculated considering the total increase in inorganic carbon in each vial, including both headspace CO₂-C and seawater DIC. CO₂-C production was normalized to soil/sediment dry weight and OC content. Results from triplicate subsamples were averaged before further analysis. In a few cases where gas samples were lost, an average of two replicates were used instead of three. CO₂-C production rates were calculated using the slope of a linear regression model of cumulative production over time. Additionally, OC loss (%) was calculated by comparing the CO₂-C produced over 40 days to the initial soil/sediment OC content.

Abstract:

Arctic coastal erosion rates are accelerating due to increases in temperature, declines in sea ice extent, and the increasing length of the open-water season. Increasing erosion puts critical infrastructure and native communities at risk. Additionally, erosion mobilizes large quantities of organic-rich permafrost to the ocean where it may be decomposed, producing greenhouse gases. While Arctic coastlines compromise one-third of the global coastline, current models for estimating erosion are unable to adequately explain episodic, storm-driven events. This Arctic coastal erosion modeling project mechanistically coupled oceanographic and atmospheric boundary conditions with a terrestrial permafrost model to capture the thermo, chemical, and mechanical dynamics of erosion.

To aid development of the terrestrial model component and to estimate land-to-ocean fluxes of geochemical constituents, we completed extensive analyses of permafrost cored near Drew Point, Alaska, including geochemical and material properties of these permafrost core samples.
