CISNet Datasets

The following downloadable data files are compressed comma-delimited text files. A decompression software program is required to access the zip data files. Brief summaries as to the content of the data files are provided below. For more detail, see the metadata files. They consist of file names, time period covered, descriptions of variables, frequency of recordings, condition of data, and GPS coordinates and water depth of sampling stations.


Ac-9 Continuous Monitoring

The WETLabs Spectral AC-9 meter was programmed to collect hourly attenuation and absorption coefficients at wavelengths 412, 440, 488, 510, 532, 555, 650, 676, and 715 nm. The data file contains these eighteen light measurements along with the year, month, day, Julian day, and hour. Samples were collected at a single site (4B, Sta = 3.8) on the Rhode River (see map below). The variable Sta identifies the distance (km) of the field stations along the Rhode River from the mouth.

Spectral Diffuse Attenuation Coefficients

The Satlantic OCI 200 irradiance sensors were used to collect upwelling and downwelling spectral irradiance profiles on a weekly basis at three to five field stations (see map below) along the Rhode River. The data file consists of year, month, day, Sta, profnum, Kd PAR, and Kd values at wavelengths 325, 340, 380, 412, 443, 490, 510, 532, 555, 620, 665, 683, and 705 nm. The variable Sta identifies the distance (km) of the field stations along the Rhode River from the mouth. The variable profnum in the data file identifies the sample order of the profiles taken on the same day.

Water Quality

Integrated water samples were collected at three to five field stations (see map below) along the Rhode River, coinciding with weekly Satlantic profiles . Laboratory analyses on these water samples were made to determine concentrations of suspended particulate matter, colored dissolved organic matter, and phytoplankton chlorophyll. Light measurements were made on whole and filtered (Poretics, 0.22 micron) samples using a WETlabs AC-9 meter and a Carey spectrophotometer.

The data file WaterQuality.zip consists of year, month, day, profnum, Sta, total and fixed suspended solids (mgL-1), and chlorophyll a (µgL-1). The variable Sta identifies the distance (km) of the field stations along the Rhode River with respect to the mouth. The variable profnum in the data file identifies the sample order of the profiles taken on the same day.

The data file AC9Total&FF440 consists of year, month, day, profnum, Sta, and attenuation and absorption coefficients at wavelengths 412, 440, 488, 510, 532, 555, 650, 676, and 715 nm . The data file also includes absorption coefficient at 440 nm by colored dissolved organic matter after filtration.

Salinity Monitors

Four salinity monitors were deployed at various positions along the Rhode River (see map below) to collect data hourly. The downloadable data files consists of year, month, day, Julian day, hour, temperature (°C), conductivity (μScm-1), and salinity (ppt). The variable Sta identifies the distance (km) of the field stations along the Rhode River from the mouth.
