Naval Research Laboratory Ecological -- Photochemical -- Bio-optical-- Numerical Experiment (Neptune) Version 1: A Portable, Flexible Modeling Environment Designed to Resolve Time-dependent Feedbacks Between Upper Ocean Ecology, Photochemistry, and Optics

摘要

A modeling system has been constructed that combines ecological element cycling, photochemical processes, and bio-optical processes into a single simulation that may be coupled to hydrodynamic models that provide temperature fields as well as the advection/diffusion of state variables. The model is derived from a history of ocean biogeochemical models that describe the transformation of elemental reservoirs (carbon, nitrogen, phosphorus) based upon lower-trophic order ecosystem function. The model description of the relationship between reservoirs of organic carbon and optical properties permits the use of satellite ocean color data to validate and constrain the model. The model has been coupled to the Modular Ocean Data Assimilation System, which permits examination of the one-dimensional case in any region of interest around the globe.
