Journal ArticleDOI
Ocean forecasting in terrain-following coordinates: Formulation and skill assessment of the Regional Ocean Modeling System
Dale B. Haidvogel,Hernan G. Arango,W. P. Budgell,Bruce D. Cornuelle,Enrique N. Curchitser,E. Di Lorenzo,Katja Fennel,W. R. Geyer,Albert J. Hermann,L. Lanerolle,Julia Levin,James C. McWilliams,Arthur J. Miller,Andrew M. Moore,Thomas M. Powell,Alexander F. Shchepetkin,Christopher R. Sherwood,Richard P. Signell,John C. Warner,John Wilkin +19 more
TL;DR: The combination of moderate-order spatial approximations, enhanced conservation properties, and quasi-monotone advection produces both more robust and accurate, and less diffusive, solutions than those produced in earlier terrain-following ocean models.
Journal ArticleDOI
Nitrogen cycling in the Middle Atlantic Bight: Results from a three‐dimensional model and implications for the North Atlantic nitrogen budget
TL;DR: In this paper, a high-resolution physical-biological model for the U.S. east coast continental shelf and adjacent deep ocean was developed to estimate nitrogen fluxes in the shelf area of the Middle Atlantic Bight (MAB).
Journal ArticleDOI
The rise of oxygen over the past 205 million years and the evolution of large placental mammals.
Paul G. Falkowski,Miriam E. Katz,Allen J. Milligan,Katja Fennel,Benjamin S. Cramer,Marie-Pierre Aubry,Robert A. Berner,Michael J. Novacek,Warren M. Zapol +8 more
TL;DR: It is suggested that the overall increase in oxygen, mediated by the formation of passive continental margins along the Atlantic Ocean during the opening phase of the current Wilson cycle, was a critical factor in the evolution, radiation, and subsequent increase in average size of placental mammals.
Journal ArticleDOI
Subsurface maxima of phytoplankton and chlorophyll: Steady-state solutions from a simple model
Katja Fennel,Emmanuel Boss +1 more
TL;DR: A quantitative criterion for the observed coexistence of vertically distinct phytoplankton assemblages in oligotrophic systems is suggested: the vertical position at which a species occurs in highest abundance in the water column is determined by the ‘‘general compensation depth’’— that is, the depth at which specific growth and all loss rates, including the divergence of sinking/swimming and vertical mixing, balance.

TL;DR: The objective is to create a fully global, top-to-bottom, dynamically complete, and multidisciplinary Argo Program that will integrate seamlessly with satellite and with other in situ elements of the Global Ocean Observing System.
