gadget3: Globally-Applicable Area Disaggregated General Ecosystem Toolbox V3

A framework to assist creation of marine ecosystem models, generating either 'R' or 'C++' code which can then be optimised using the 'TMB' package and standard 'R' tools. Principally designed to reproduce gadget2 models in 'TMB', but can be extended beyond gadget2's capabilities. Kasper Kristensen, Anders Nielsen, Casper W. Berg, Hans Skaug, Bradley M.

(2004) <> "An overview of Gadget, the globally applicable area-disaggregated general ecosystem toolbox. ICES.".
