Description

Model input, output and code for individual-based copepod Calanus finmarchicus populations in Wilkinson Basin (WB), Gulf of Maine. Model output files contain results of backward tracking individal-based runs for copepod Calanus finmarchicus populations.

This model was published in Ji et al., 2017.

Methods & Sampling

Backward tracking individual-based runs for Wilkinson Basin (WB) copepod Calanus finmarchicus populations in the Gulf of Maine.

The detailed description of modeling concepts, equations and interpretation can be found in Ji, et al. (2017):

Methodology summary:
An individual-based model (IBM) was utilized to conduct copepod Lagrangian tracking and life stage development experiments. The model simulations were conducted in the so-called “offline” mode, i.e. the hydrodynamic model simulations were conducted prior to the IBM runs to provide flow fields for Lagrangian tracking and temperature for copepod life stage development. Both flow and temperature fields are stored to allow multiple numerical experiments later, precluding the need to re-run the physical model.

* Copepod life history development is modeled based on temperature- and food-dependency.
* Temperature and flow field are interpolated from FVCOM-GOM3 model forcing.
* Food is estimated from MODIS satellite chlorophyll product.
* Two tracking schemes are used: depth-keeping and DVM.

The hydrodynamic model that generated the forcing data is the 3rd generation Gulf of Maine - Finite Volume Community Ocean Model (FVCOM) developed by collaborators at University of Massachusetts. More details can be found at http://fvcom.smast.umassd.edu/necofs/
