title: Modelling past, present and future peatland carbon accumulation across the pan-Arctic

description: Most northern peatlands developed during the Holocene, sequestering large amounts of carbon in terrestrial ecosystems. However, recent syntheses have highlighted the gaps in our understanding of peatland carbon accumulation. Assessments of the long-term carbon accumulation rate and possible warming driven changes in these accumulation rates can therefore benefit from process-based modelling studies. We employed an individual- and patch-based dynamic global ecosystem model with dynamic peatland and permafrost functionality and vegetation dynamics to quantify long-term carbon accumulation rates and to assess the effects of historical and projected climate change on peatland carbon balances across the pan-Arctic. Our results are broadly consistent with published regional and global carbon accumulation estimates. A majority of modelled peatland sites in Scandinavia, Europe, Russia and Central and eastern Canada change from carbon sinks through the Holocene to potential carbon sources in the coming century. In contrast, the carbon sink capacity of modelled sites in Siberia, Far East Russia, Alaska and western and northern Canada was predicted to increase in the coming century. The greatest changes were evident in eastern Siberia, northwest Canada and in Alaska, where peat production, from being hampered by permafrost and low productivity due the cold climate in these regions in the past, was simulated to increase greatly due to warming, wetter climate and greater CO2 levels by the year 2100. In contrast, our model predicts that sites that are expected to experience reduced precipitation rates and are currently permafrost free will lose more carbon in the future.

title: (Table 1) Age determination of sediment core SO147_106KL

description: Here we present a high-resolution marine sediment record from the El Niño region off the coast of Peru spanning the last 20,000 years. Sea surface temperature, photosynthetic pigments, and a lithic proxy for El Niño flood events on the continent are used as paleo-El Niño-Southern Oscillation proxy data. The onset of stronger El Niño activity in Peru started around 17,000 calibrated years before the present, which is later than modeling experiments show but contemporaneous with the Heinrich event 1. Maximum El Niño activity occurred during the early and late Holocene, especially during the second and third millennium B.P. The recurrence period of very strong El Niño events is 60-80 years. El Niño events were weak before and during the beginning of the Younger Dryas, during the middle of the Holocene, and during medieval times. The strength of El Niño flood events during the last millennium has positive and negative relationships to global and Northern Hemisphere temperature reconstructions.

description: We collected PCB analysis results from multiple sources (French Water Basin Agencies, Port Authorities, Research Laboratories) to produce a spatio-temporal database of PCB contamination in sediments along the main French Rivers (source-estuary) from 1945 to 2018. This database contains data from bed and flood deposits, cores, suspended particulate matter and dredged sediments. It presents sediment concentrations of PCB indicators (PCB28, 52, 101, 118, 138, 153, 180; µg/kg) and their sum or reconstructed sum according to the porportion of highly chlorinated congeners (PCB 138, 153 and 180).

title: Edge Artifact Correction for Doppler Time-of-Flight Radial Velocity Imaging Based on Adaptive Gradient Threshold

description: Doppler time-of-flight (Do-ToF) imaging has recently attracted significant attention due to its high-resolution capabilities for measuring radial velocity. However, a challenge arises when the back-reflected signal received by pixels switches between a moving object and a stationary background, leading to the appearance of edge artifacts in the velocity images. To address this issue, we propose a per-pixel gradient-based method for identifying and correcting these artifacts. First, the homodyne measurement was modelled to acquire the gradient feature of regular pixels and those affected by edge artifacts. Building on this, we proposed a self-adaptive gradient threshold method to accurately identify artifacts, thereby addressing misidentification caused by sinusoidal patterns in the moving objects' measurements. The identification method was implemented with five continuous results to determine edge artifacts. The linear prediction was referred to correct the artifact region. Experimental results demonstrate that the proposed method effectively reduces edge artifacts. The average velocity error was reduced by 78.5% compared to the original results. The root mean square error (RMSE) was reduced by 62.7%. The effectiveness of the adaptive gradient threshold was validated, with the RMSE reducing by 31.1% compared to the preset gradient threshold.
