title: Data for: Integrated multi-trophic aquaculture with sugar kelp and oysters in a shallow coastal salt pond and open estuary site

description: The data set includes environmental data as well as kelp and oyster data
 from an integrated multi-trophic aquaculture study where sugar kelp was
 planted on four established oyster farms in Rhode Island, USA over 2
 growing seasons (Year 1 = 2017–2018; Year 2 = 2018-2019). At each site, we
 planted 60 m kelp lines (denoted as Line 1 and Line 2) approximately three
 weeks apart to determine optimal planting time. Kelp blade length and
 width were recorded at periodic intervals, and tissues were collected for
 carbon, nitrogen, δ15N, and δ13C analyses. Oyster growth data was
 collected from the same sites across the same timespans. Environmental
 data includes data collected on monthly farm visits with a YSI Sonde, as
 well as dissolved nutrients in the seawater. In addition, temperatures
 were logged on kelp lines every 15 minutes during each growing season.
description: There are several files in this dataset; the Readme file
 describes all of the details for each file.  - Data on
 organism (kelp, oyster) length and width and survivorship were measured in
 the field (or occasionally in the lab), using SI units where appropriate.
 These files are: Kelp Peformance Data 2017_2019, Oyster Performance
 2018_2019, Oyster Survivorship. -From these data, we
 calculated total kelp biomass/production. These calculations and
 associated data can be found in the file: Kelp Nutrient
 Extraction. - Subsamples of ground kelp tissue (2–3 mg)
 were encapsulated in tins (3.5 × 5 mm) and analyzed at the United States
 Environmental Protection Agency, Atlantic Division Laboratory in
 Narragansett, RI, USA. Carbon, nitrogen, δ<sup>15</sup>N, and
 δ<sup>13</sup>C content of tissue samples was measured using
 an Isoprime 100 Isotope Ratio Mass Spectrometer interfaced with a Micro
 Vario Elemental Analyzer (Elementar Americas, Mt. Laurel, New Jersey,
 USA). These files are: Kelp Carbon Nitrogen Results 2017_2018 and Kelp
 Carbon Nitrogen Results 2018_2019. -Dissolved nutrient
 concentrations in the ocean water were determined from water samples; all
 data (nitrate, nitrite, ammonium, phosphate) are raw data.  The file is:
 Dissolved Nutrient Raw data. -Environmental raw data
 (temperature, conductivity, salinity, pH, pHmV, dissolved oxygen% and
 mg/L, Chlorophyll a, fluroescence) were conducted from YSI 6560 Sonde
 lowered in the field in situ. The file is: Environmental Data from YSI
 Sonde_2017-2019'. -Field temperatures throughout
 the study period were collected via Onset HOBO temperature loggers at each
 site.  Raw data were modified as follows: we excluded the day when we
 visited sites, as temperatures were logged when the loggers were removed
 from the water to be sampled and checked. There are four
 files: “Narragansett Bay N_Temperature_2017-2019”, “Narragansett Bay
 S_Temperature_2017-2019”, “Point Judith Pond N_Temperature_2017-2019”, and
 “Point Judith Pond S _Temperature_2017-2019”
description: Apart from the Readme.md file, all files are .xslx, so Microsoft
 Excel, Google Sheets, or equivalent, would be needed.
