Abstract The Arctic experiences climate changes that are among the fastest in world and affect all Earth system components. Despite expected increase terrigenous inputs to Ocean, their impacts on biogeochemical cycles currently largely neglected IPCC-like models. Here we used a state-of-the-art high-resolution ocean biogeochemistry model includes carbon nutrient from rivers coastal erosion produce twenty-first-century pan-Arctic projections. Surprisingly, even with an anticipated rise...
Abstract. This study describes the coupling of process-based Model Early Diagenesis in Upper Sediment with Adaptable complexity (MEDUSA version 2) to an existing ocean biogeochemistry model consisting Finite-volumE Sea ice–Ocean (FESOM 2.1) and Regulated Ecosystem (REcoM 3). Atmospheric CO2 is a prognostic variable which determined by carbonate chemistry surface ocean. The setup its application pre-industrial control climate state described detail. In coupled model, 1390 PgC stored top 10 cm...
Changes in the marine biological carbon pump during glacial times have been supposed to contribute CO2 drawdown. One particular hypothesis that received attention last two decades is Silicic Acid Leakage Hypothesis (SALH), which proposed Si leakage from Southern Ocean (SO) was transported towards lower latitudes and then contributed enhanced productivity there thus global cooling by lowering atmospheric pCO2.Thanks flexible stoichiometry (C:N:Si:Chl ratios) implemented biogeochemistry model...
The ongoing increase of global mean temperature, caused by anthropogenic CO2 emissions, will most likely lead to enhanced melting and calving Antarctic ice shelves in the coming decades. As a consequence, freshwater input into Southern Ocean is expected as well. resulting change ocean salinity could have significant consequences for circulation, water column stratification, mass formation Ocean, which are all affect capacity surface remove from atmosphere, sequestration carbon deep ocean....

In September 2023, the Fire Learning AcRoss Earth Systems (FLARE) workshop brought together fire scientists across a wide range of disciplines, including physical and social representatives fire-prone communities, with aim to facilitate transdisciplinary discussion. The FLARE community identified characterizing “fire extreme events” as research priority. recent years, there has been rise in weather events worldwide. Both science media, word...
Abstract. Arctic coastal ecosystems are rapidly changing due to climate warming, which makes modelling their productivity crucially important better understand future changes. System primary production in these systems is highest during the pronounced spring bloom, typically dominated by diatoms. Eventually blooms terminate silicon or nitrogen limitation. Bacteria can play an role for extending bloom duration and total CO2 fixation through ammonium regeneration. Current ecosystem models...
