Salpa thompsoni is an important grazer in the Southern Ocean. Their abundance in the western
Antarctic Peninsula is highly variable, varying by up to 5000-fold inter-annually. Here, we use a
particle-tracking model to simulate the potential dispersal of salp populations from a source location
in the Antarctic Circumpolar Current (ACC) to the Palmer Long Term Ecological Research (PAL LTER)
study area. Tracking simulations are run from 1998 to 2015, and compared against both a stationary
salp population model simulated at the PAL LTER study area and observations from the PAL LTER
program. The tracking simulation was able to recreate closely the long-term trend and the higher
abundances at the slope stations. The higher abundances observed at slope stations are likely due to
the advection of salp populations from a source location in the ACC, highlighting the signifcant role of
water mass circulation in the distribution and abundance of Southern Ocean salp populations.
