LOSCAR: Long-term Ocean-atmosphere-Sediment CArbon cycle Reservoir Model v2.0.4

Abstract: Abstract. The LOSCAR model is designed to efficiently compute the partitioning of carbon between ocean, atmosphere, and sediments on time scales ranging from centuries to millions of years. While a variety of computationally inexpensive carbon cycle models are already available, many are missing a critical sediment component, which is indispensable for long-term integrations. One of LOSCAR's strengths is the coupling of ocean-atmosphere routines to a computationally efficient sediment module. This allows, for … Show more

“…That is, a few ten thousand years after the carbon input has stopped, the position of the CCD is deeper than its position before the event and remains suppressed on a time scale of 100 kyr or more (figure 2d). Note that, while figure 2d shows examples for the Atlantic CCD, the model-predicted CCD overshoot is global [11,31]. The cause for the CCD overshoot can be traced back to the weathering feedback.…”

“…Given the limitations of stratigraphy, numerical tools are required to provide additional constraints on the time scale of the PETM carbon release, for example by using carbon cycle models that include a sediment component [11,31]. Simulations of the carbon release with a single input of 3000 Pg C (source δ 13 C = −50 ) indicate that the release time was probably much shorter than 20 kyr, otherwise the shoaling of the calcite compensation depth (CCD) in the deep Atlantic would be too muted (figure 2).…”
