Simulation of the Planktonic Ecosystem Response to Pre- and Post-1976 Forcing in an Isopycnic Model of the North Pacific
Entry ID: GLOBEC_030_CAN_007

[ Update this Record ]

Summary
Abstract: A four-component planktonic ecosystem model in an ocean general
circulation model was used to investigate fluctuations in North Pacific fish
populations. The Miami isopycnic model (MICOM) was implemented on a 2° grid
over the domain, from 18°S to 61°N, with a Kraus-Turner-type mixed layer model
overlaying 10 isopycnal layers. An initial baseline run with forcing for the
period 1952-1988 reasonably ... View entire text

Purpose: To investigate the hypothesis that the 1976 "regime shift" in North
Pacific fish populations resulted from climatic change propagating up the
fisheries food web.
