CO2 fluxes in Estuarine Regions
The slides are from a lecture, presented at Xiamen University, that introduced estuaries, CO2 fluxes in estuaries, CO2 spatiotemporal variability, net heterotrophy - a main CO2 driver (along with freshwater input), the significance of it all in the global carbon cycle, and the concluding remarks. The outline of the talk is based on a must-read article titled "Carbon Dioxide and Methane Dynamics in Estuaries" by AV Borges and G Abril.
Permanent El Niño during the Pliocene warm period not supported by coral evidence – A climate proxy via coral
The slides are from a brief talk, presented at Xiamen University, that discussed the Pliocene Warm Period, the El Niño Southern Oscillation (ENSO), and the coral-sourced methods used to determine past climate change
Metal Ligand Solution Complex INteractions With Planktonic Cell Surfaces
The slides, presented at a GEOTRACES workshop, introduces trace metal uptake, and examines intercellular transport, pH reductions the protein receptor sites, and ligand competition
Estimations of Anthropogenic CO2 inventories in the ocean
The slides are from a brief talk about Sabine and Tanhua's article in 2010, presented at C.O.O.L., that discussed the updated the anthropogenic CO2 inventories methodologies to present-day
Evolution of the Oceanic 13C Suess Effect in the Southeastern Indian Ocean Between 1994 and 2018
The slides are from a brief talk about an article in 2020 by Williams et al., presented at C.O.O.L., that discussed the 13C Suess Effect in the Southeastern Indian Ocean, including it's relationship with anthropogenic carbon storage within subsurface water masses, and long-term trends
The Sensitivity of the Marine Carbonate System to Regional Ocean Alkalinity Enhancement (OAE)
The slides are from a brief talk about an article in 2021 by Burt et al., presented at C.O.O.L., that discussed marine carbonate system sensitivity to regionally applied OAE based on modelling results. The article includes results on the influence of total alkalinity surface distribution on carbon and discussion on the drivers of the marine carbonate system response to OAE
