  • Instantaneous discharge, suspended sediment, and organic carbon fluxes in the Canning River, Alaska, June-July 2022 and July-August 2023
Title: Instantaneous discharge, suspended sediment, and organic carbon fluxes in the Canning River, Alaska, June-July 2022 and July-August 2023
This dataset contains measurements of river discharge, suspended sediment, and organic carbon fluxes in the Canning River, Alaska during one field campaign from 28 June to 10 July 2022 and a second field campaign from 21 July to 2 August 2023. The purpose of this dataset is to demonstrate the impact of summer convective storms on river suspended sediment and particulate organic carbon fluxes in Arctic Rivers. During the 2022 field campaign, we rafted down the Canning River starting on the upper Canning within the headwaters and ending near the mouth at the Beaufort Sea coast. During this campaign, we selected five locations along the active channel to conduct Acoustic Doppler Current Profiler (ADCP) surveys to measure river discharge and sample the river water for suspended sediment and particulate organic carbon, where T1 is the farthest upstream transect and T5 is the farthest downstream. During the 2023 field campaign, we collected instantaneous river discharge measurements of the Canning River in the headwaters at the Marsh Fork Bench Airstrip, at the Staines Airstrip, and on the Staines branch of the Canning River delta. We observed several thunderstorms during these field campaigns, during which the river water level and suspended load increased dramatically, prompting us to sample river suspended sediment during these events. This dataset includes ADCP measurements of river water discharge, suspended sediment concentrations, particulate and dissolved organic carbon concentrations, woody debris flux measurements, and estimates of instantaneous fluxes.  more » « less

    Permafrost holds more than twice the amount of carbon currently in the atmosphere, but this large carbon reservoir is vulnerable to thaw and erosion under a rapidly changing Arctic climate. Convective storms are becoming increasingly common during Arctic summers and can amplify runoff and erosion. These extreme events, in concert with active layer deepening, may accelerate carbon loss from the Arctic landscape. However, we lack measurements of carbon fluxes during these events. Rivers are sensitive to physical, chemical, and hydrological perturbations, and thus are excellent systems for studying landscape responses to thunderstorms. We present observations from the Canning River, Alaska, which drains the northern Brooks Range and flows across a continuous permafrost landscape to the Beaufort Sea. During summer 2022 and 2023 field campaigns, we opportunistically monitored river discharge, sediment, and organic carbon fluxes during several thunderstorms. During one notable storm, river discharge nearly doubled from ~130 m3/s to ~240 m3/s, suspended sediment flux increased 70-fold, and the particulate organic carbon (POC) flux increased 90-fold relative to non-storm conditions. Taken together, the river exported ~16 metric tons of POC over one hour of this sustained event, not including the additional flux of woody debris. Furthermore, the dissolved organic carbon (DOC) flux nearly doubled. Although these thunderstorm-driven fluxes are short-lived (hours to days), they play an outsized role in exporting organic carbon from Arctic rivers. Understanding how these extreme events impact river water, sediment, and carbon dynamics will help predict how Arctic climate change will modify the global carbon cycle.

    We are interested in borrowing seismic sensors to collect a pilot dataset that captures river bedload transport and river ice breakup in the Canning River on Alaska's North Slope. We have two field campaigns this year in which we would like to deploy these sensors: 1) March 22 - April 2 2023, and 2) July 14 – August 6 2023. River ice will be pervasive in the March-April field campaign, so we want to deploy a geophone and datalogger to record the dynamic movements of river ice, and determine whether there is water flowing beneath the ice. In the July-August field campaing, our goal is to use the geophone to record river bed sediment transport. The Canning River is a gravel bed river and we want to determine how much of this gravel moves during and after river ice breakup. We are looking for a 4.5 Hz 3-channel geophone and datalogger for these field campaigns.

    Abstract The Tocantins River contributes ∼5% of the total flux of water to the Amazon River plume in the Atlantic Ocean. Here, we evaluate monthly variability in the composition and abundance of carbon, nitrogen, and suspended sediment in the lower reaches of the Tocantins River from 2014 to 2016. Dissolved organic carbon concentrations generally increased during periods of high discharge and are ∼1.5 times lower than average concentrations at the mouth of the Amazon River. Dissolved inorganic carbon similarly increased during periods of high discharge. Total dissolved nitrogen and individual nitrogen species followed a similar temporal pattern, increasing during high water.predominated the dissolved inorganic nitrogen pool, followed by, and, characteristic of environments with a relatively low anthropogenic impact. Dissolved fractions represented 92% of the total carbon exported and 78% of the total nitrogen exported. The suspended particulate sediment flux was 2.72 × 106 t yr−1, with fine suspended sediment dominating (71.3%). Concentrations of carbon relative to nitrogen indicate a primarily terrigenous source of organic matter and CO2derived from in situ respiration of this material during the rainy season and a primarily algal/bacterial source of organic matter during the dry season. Considering past estimates of dissolved carbon and nitrogen fluxes from the Amazon River to the Atlantic Ocean, the Tocantins River contributes 3% and 3.7% to total fluxes to the Amazon River plume region, respectively. While this contribution is relatively small, it may be influenced by future changes to the basin's land use and hydrology.

    The Arctic region is experiencing accelerated temperature increases, which has been driving increased rates of permafrost thaw and causing changes in the physical and chemical dynamics of Arctic landscapes. One such change is in the timing and magnitude of spring river ice breakup and flooding. It is difficult to observe river ice breakup in remote Alaskan rivers, and even more difficult to collect samples of river bedload and suspended load during ice breakup events. Building on a geophysical dataset collected on the Canning River in summer 2023, we deployed three geophones during river ice breakup and continuously recorded the signals generated by river ice breakup and river discharge rise in the Canning River, Alaska during this dynamic period. We deployed three SmartSolo geophones (IGU-16HR 3C Multi Channel Data Loggers) on an elevated floodplain surface at 20, 30, and 40 m from the bank of the Canning River from 28 May through 24 June 2024. Unfortunately, only two nodes were recovered (stations 2 and 3 at 30 and 40 m from the river bank, respectively). Using the recorded geophone data, we will work to translate the seismic signals into river ice movement, bedload sediment transport, and stage height changes. These data will provide key information on the timing and driving mechanisms of river bank erosion, soil carbon loss, and sediment transport rates in changing Arctic river systems.
