TL;DR: The North Pacific Ecosystem Model for Understanding Regional Oceanography (NEMURO) as discussed by the authors is a lower trophic level ecosystem model for the North Pacific Ocean, which has eleven state variables: nitrate, ammonium, small and large phytoplankton biomass.
Journal ArticleDOI
End-To-End Models for the Analysis of Marine Ecosystems: Challenges, Issues, and Next Steps
Kenneth A. Rose,J. Icarus Allen,Yuri Artioli,Manuel Barange,Jerry Blackford,Francois Carlotti,Roger Allan Cropp,Ute Daewel,Karen P. Edwards,Kevin J. Flynn,Simeon L.

TL;DR: End-to-end modeling is in its early developmental stages and thus presents an opportunity to establish an open-access, community-based approach supported by a suite of true interdisciplinary efforts.
Journal ArticleDOI
Challenges of Modeling Ocean Basin Ecosystems
Brad deYoung,Michael R. Heath,Francisco E. Werner,Fei Chai,Bernard A. Megrey,Patrick Monfray +5 more
TL;DR: A strategy is discussed that builds on recent advances in modeling and observations and a way forward is suggested that includes approaches to coupling across trophic levels and the inclusion of uncertainty.
Journal ArticleDOI
A bioenergetics-based population dynamics model of Pacific herring (Clupea harengus pallasi) coupled to a lower trophic level nutrient-phytoplankton-zooplankton model: Description, calibration, and sensitivity analysis
Bernard A. Megrey,Kenneth A. Rose,Robert A. Klumb,Douglas E. Hay,Francisco E. Werner,David L. Eslinger,S. Lan Smith +6 more
TL;DR: An approach to dynamically couple a fish bioenergetics-based population dynamics model to the NEMURO lower trophic level nutrient–phytoplankton–zooplankton model for Pacific herring growth and population dynamics is described.
Journal ArticleDOI
Development of a spatially explicit, individual-based model of marine fish early life history
TL;DR: This simulation shows that inclusion of specific mechanisms which determine depth of individual eggs or larvae at particular periods of their development are Important in determ~ning the direction of horizontal advect~on, and the history of exposure to environmental variables for each individual.
