Methods & Sampling

Location: Hawaii Ocean Time-series (HOT) and nearby regions (5deg x 5deg centered at HOT)

These data were generated from numerical model simulations.

See Supplemental File "Liu_and_Levine_modelDescription.pdf" for a methodology summary including a physical model description, ecological model description, model configuration and simulations, and Appendix A. "Key ecosystem parameters used in the model. Parameters optimized for the HOT site are denoted with asterisks."

Model output files containing simulated biogeochemical parameters averaged over the entire model domain in MATLAB .mat format.

Each .mat file contains 12 years of model output from 2003 to 2014, and there are a total of 57 files corresponding to the 56 sensitivity heterogeneous mode experiments.

File names:

A suite of modeling experiments was conducted and a MATLAB file was generated for each of these experiments:

Example:

Rv120_`aa`Year_`bb`_`cc`_`dd`min_`ee`dflux_`ff`day.mat

where:

`aa` = total length of the simulation

`bb` = start year of the simulation

`cc` = end year of the simulation

`dd’ = time step for model evolution and numerical integration

`ee` = disturbance flux in meters per day

`ff` = disturbance duration in days

Key parameters:

In each file, simulated biogeochemical parameters averaged over the entire model domain are saved in a MATLAB data structure named “PATCH”:

DAY: time elapsed since the start of the simulation in days

SST: sea surface temperature in degree C

NO3: nitrate concentration in mmol per cubic meter

NH4: ammonium concentration in mmol per cubic meter

PHYTO_C: **phytoplankton carbon biomass concentration in mmol per cubic meter

GROWTH_C: **phytoplankton carbon biomass production in mmol per cubic meter per day

PHYTO_CHL: **phytoplankton chlorophyll concentration in mg per cubic meter

ZOO_C: zooplankton carbon biomass concentration in mmol per cubic meter

POC: particulate organic carbon concentration in mmol per cubic meter

DOC: dissolved organic carbon concentration in mmol per cubic meter

EXPORT_C: particulate organic carbon exported vertically out of the model domain

FLUX: vertical flux dissolved nitrogen from the deep boundary layer into the model domain

**: these phytoplankton related parameters were simulated for three functional/size groups: small phytoplankton (row 1), large phytoplankton (row 2), and diazotrophs (row 3).
