Using Monitoring and Mechanistic Modeling to Improve Understanding of Eutrophication in a Shallow New England Estuary

This data repository contains the names and description of data files used in the “Using Monitoring and Mechanistic Modeling to Improve Understanding of Eutrophication in a Shallow New England Estuary” manuscript by Cashel et al (2023). These data files, formatted as .txt files, include simulated and observed data of various water quality components with time. Time is always provided as the Julian Day in the first column (left). The type of data in each file is indicated by a parameter code. Parameter codes are defined below.

SAL = salinity (ppt)

WT = water temperature (℃)

PAR = photosynthetically active radiation (W/m2)

TN = total nitrogen (mg/L as N)

NH3 = ammonium (mg/L as N)

NO3 = nitrate + nitrite (mg/L as N)

TP = total phosphorus (mg/L as P)

DIP = orthophosphate (mg/L as P)

CBOD = carbonaceous biological oxygen demand (mg/L)

CHL = phytoplankton as chlorophyll a (µg/L)

MACRO = macroalgae biomass (gDW/m2)

DO = dissolved oxygen (mg/L)

1 - Simulated Data

1.1 – PRE Model Data

            The primary simulated data for this study includes model output on an interval of 0.05 days. Columns two through eight contain the average concentration of each WASP Segment per each time step. Data presented in these columns from left to right are from WASP Segments 8, 9, 10, 12, 14, 16, and 17.

1.2 – Macroalgae Scenario Data

            Simulated data files also include a model scenario evaluating the impact of macroalgae as a state variable. This set of model output comes from simulations with macroalgae removed as a state variable. These files have a model output of 0.05 days with time in the first column, and the second column contains the average concentration within WASP segment 17.

1.3 – Dissolved Oxygen Parameter Analysis Data

            Simulated data from model scenarios evaluating the impact of parameterization on dissolved oxygen concentrations are listed below. These model simulations have an output of 0.05 days. Rows two through ten contain average DO concentration (mg/L) for WASP Segments 9, 10, 11, 12, 13, 14, 15, 16, and 17. Files containing “1” indicate the high condition of each parameter analysis, and those with a “2” indicate the low condition.

1.4 – Heatmap Simulations

            Simulated data for heatmaps presents average concentrations from noon of each day. The first row is time, and the following rows of two through nine have simulated data for WASP Segments 10, 11, 12, 13, 14, 15, 16, and 17.

2 – Observed Data

2.1 – Sonde Data

            Observed sonde data is presented in .txt files from various years and location. Each data file has the first column of time, and the second column as concentration per each time step. File names begin with the site name, followed by an “S” or “B” (surface and bottom respectively, if applicable), the year, and the parameter code. Site names are: LNB (Little Narragansett Bay), Pawcatuck (Pawcatuck Point), Avondale (Avondale Marina), Greenhaven (Greenhaven Marina), WYC (Westerly Yacht Club), PR (Pawcatuck Rock), Viking (Viking Marina), and R1 (Route 1). File names per location are provided in the two tables below. Row 1 of each table has the site name, and the corresponding files are listed below.
