Service Description: These data represent the seasonal cycle for chlorophyll-a and pH data collected from 2018-2023 for specified sites in the Mid-Atlantic Bight, Barnegat Bay, Chesapeake Bay, Delaware Bay, and offshore New Jersey. Seasons were categorized as active or inactive (relative to phytoplankton biomass growth) using the first order derivative of chlor-a, and are site-specific. For each season, pH and chlor-a values in that period were averaged.
Chlorophyll-a Data:
Chlorophyll-a satellite product (Gap-filled DINEOF: NOAA S-NPP NOAA-20 VIIRS and Copernicus S-3A OLCI). Science Quality, 2km Resolution, 01-01-2018 to 12/31/2023, Daily Files. Downloaded from NOAA CoastWatch program with support from the NOAA NESDIS Ocean Color Science Team between March 11th and 22nd. Optical penetration depth was not provided, but is understood to generally be <= 3m, with pixel depth variations due to differences in mixed layer depth.
pH Data:
pH measurements were taken from multiple in-situ sources, including gliders, cruises, and continuous monitoring buoys. Listed below are the sampling missions whose data was used for my calculation for site-specific pH, whose sample coordinates were then used to index for nearby chlor-a pixels.
- CSIO: Citizen Science Initiative: Oyster (data provided by Emily Rivest at VIMS).
- EOTB: Eyes on the Bay (www.eyesonthebay.net)
- National Estuary Program, Barnegat Bay Partnership (data QA/QCÕed by Janet Reimer, provided by Nicole Petersen and Stephen Pacella)
Rutgers University ru30 Glider (dataset authors: Grace K. Saba, Lori M. Garzio, Laura J. Nazzaro, John Kerfoot)
- NYOS: New York Bight NYOS Glider (FLAG: check citation style NYB_2019_2021_Surface.csv, Janet Nye provided the data).
- NOAA ECOA3 Cruise.
- Delaware Estuary Water Quality Monitoring Program Boat Run data provided by John Yagecic.
Coordinate values are used to index the chlor-a pixel closest to each pH measurement. For each row containing a window range, the averaged value of coordinate pairs during that period is provided. These values were used to plot the chlor-a pixel value (which is 2km in size) as well as the pH value for that window.
