DEVELOPING FOUR PLAUSIBLE PARAMETERISATIONS OF FOOSA (A SO-CALLED REFERENCE SET OF PARAMETERISATIONS) BY CONDITIONING THE MODEL ON A CALENDAR OF EVENTS THAT DESCRIBES CHANGES IN THE ABUNDANCES OF KRILL AND THEIR PREDATORS IN THE SCOTIA SEA
Abstract: We tuned four parameterizations of Foosa to provide predictions that are consistent ... with the agreed calendar, as specified by the WG-SAM, that describes changes in the abundances of krill ... and their predators in the Scotia Sea. First, we compiled a set of base parameterizations from ... parameterizations cover a combinatorial framework that considers krill movement (or lack thereof) and the shape of a ...
