Reconstructing salinity storage using boundary propagators

Speaker: Aurora Basinski, CAOS

Location: Online

Date: Friday, May 7, 2021, 4 p.m.

Notes:

Green's functions that represent the time-mean ocean circulation can be used to propagate surface boundary conditions into the interior of the ocean. In this talk, I will discuss using this method to recreate the change in interior salinity storage since 1955 using surface observations. This reconstruction will be analyzed in the context of surface salinity pattern amplification - the effect where regions of the ocean surface that are saltier than average in the climatological mean get saltier under climate change and vice versa. I will also compare the reconstructed change in salt storage to heat storage and comment on potential links between uptake of the two tracers.
