Distinct sources of uncertainty in simulations of the ocean biological carbon pump at different depths

Autor: Bin Wang, Katja Fennel

Publikováno v: Communications Earth & Environment, Vol 5, Iss 1, Pp 1-10 (2024)

Abstract Model uncertainty in simulating the biological carbon pump was quantified and partitioned using 14 models from the Coupled Model Intercomparison Project Phase 6. Uncertainty increases with depth. On the global scale, uncertainty in carbon ex

Estimating ocean net primary productivity from daily cycles of carbon biomass measured by profiling floats

Autor: Adam C. Stoer, Katja Fennel

Publikováno v: Limnology and Oceanography Letters, Vol 8, Iss 2, Pp 368-375 (2023)

Abstract The dependence of net primary productivity (NPP), a central metric in ecology and biogeochemistry, on sunlight drives daily cycles in carbon biomass in the ocean's euphotic zone. In this study, we infer NPP from the daily cycle of biomass. T

Abstract The marine nitrogen cycle is a main driver of ocean productivity and affects global climate. Despite decades of study, we still have an incomplete understanding of the role of the marine nitrogen cycle in the Earth system. While marine sedim

An Assessment of Vertical Carbon Flux Parameterizations Using Backscatter Data From BGC Argo

Autor: Bin Wang, Katja Fennel

Publikováno v: Geophysical Research Letters, Vol 50, Iss 3, Pp n/a-n/a (2023)

Abstract Model parameterizations of particulate organic carbon (POC) flux are critical for simulating the strength and future evolution of the biological carbon pump (BCP) but remain poorly constrained because direct observations are sparse. Here, we

The Argo Program has been implemented and sustained for almost two decades, as a global array of about 4000 profiling floats. Argo provides continuous observations of ocean temperature and salinity versus pressure, from the sea surface to 2000 dbar.
