title: Discrete profile and surface underway measurements of carbonate chemistry and others hydrographic and chemical parameters, collected during R/V Neeskay and R/V Osprey cruises in Lake Michigan from 2017-05-01 to 2022-04-30 (NCEI Accession 0259963)

description: This dataset consists of discrete profile and surface underway measurements of carbonate chemistry and others hydrographic and chemical parameters, collected during R/V Neeskay and R/V Osprey cruises in Lake Michigan from 2017-05-01 to 2022-04-30. Water chemistry and conductivity-temperature-depth (CTD) profiles were measured at several stations in Lake Michigan, ranging in depth from 10 to 55 m, in a region northeast of Milwaukee Harbor. Measurements included soluble reactive phosphorus, total dissolved phosphorus, particulate phosphorus, chlorophyll-a, the concentrations and stable isotope ratios of particulate carbon and particulate nitrogen, dissolved carbon dioxide, dissolved total inorganic carbon, and dissolved organic carbon. In addition, continuous lake surface and atmospheric CO2 data collected in 2019 and 2021 on a Lake Michigan transect between Milwaukee, WI and Muskegon MI. Measurements were made with a CO2 monitoring system mounted on a high-speed ferry that crosses the lake 4 to 6 times daily between May and October. The monitoring system consists of a "wet" box which includes a peristaltic pump that draws water from the ship's sea chest and an equilibrator in which dissolved gases are equilibrated with a recirculating air flow. The air is pumped through a desiccant to remove moisture, after which it flows to a "dry" box where it passes through an infrared gas analyzer. A similar system, without the peristaltic pump or equilibrator, is mounted near the bow of the ship to record atmospheric CO2 concentration. These chemical measurements have several applications, including: 1) Constructing an annual carbon and nutrient budget for the water column, which is used along with direct measurements of quagga mussel nutrient recycling to assess the role of invasive quagga mussels in the lake's carbon and nutrient cycles; 2) When combined with separate measurements of the vertical structure of water density and currents, to quantify vertical fluxes of dissolved nutrients and inorganic carbon, to determine how carbon and nutrient recycling by profundal quagga mussels may affect plankton production in the euphotic zone; 3) The calibration and validation of physical / biogeochemical models used to better understand how invasive quagga mussel have altered energy flow and nutrient dynamics in the Great Lakes, and guide management decisions with regard to nutrients and fish stocking.

Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry resulting in a reduction in pH, a process termed ocean acidification. In support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP), the South Florida Project Cruises (SFP) are utilized to collect water samples to measure surface water inorganic carbon and hydrographic parameters including nutrients. Samples are collected from 34 stations on a bi-monthly basis to monitor the outflow of the Shark River Slough (SRS) and red tide in the southwestern Gulf of Mexico. Water samples are sent to and analyzed by scientists at the Atlantic Oceanographic & Meteorological Laboratory (AOML) for dissolved inorganic carbon, pH, total alkalinity and nutrient concentrations. These data are used to observe the effects of the SRS on acidification in the coastal ocean.

title: Surface underway seawater and marine boundary layer observations of partial pressure of carbon dioxide (pCO2), water temperature, salinity and other parameters made during the M/V Seaspan Royal cruises in the coastal waters of British Columbia, Canada from 2022-07-01 to 2022-12-20 (NCEI Accession 0276518)

description: This dataset consists of surface underway measurements collected from the M/V Seaspan Royal as it transited the coastal waters of British Columbia, Canada from 2022-07-01 to 2022-12-20. Seawater was drawn from a depth of 2.5 m to a Sunburst SuperCO2 system and ancillary sensors from Sea-Bird Scientific. Measurements of temperature, salinity, dissolved oxygen content, and CO2 partial pressure were made every 2 seconds on seawater flowing through the system and instruments, and these data were logged by the SuperCO2 system. Seawater was delivered from the intake to analytical equipment using an AMT 1/2 HP pump (4295-98). Temperature and salinity data were collected using a Fluke thermometer (model 1523) with thermistor probe (model 5610) in the equilibrator, a Sea-Bird SBE 45 MicroTSG Thermosalinograph, and a SBE 38 Digital Oceanographic Thermometer at the seawater intake. Dissolved oxygen content was measured using a SBE63 oxygen optode. Raw oxygen measurements (with salinity reference = 0) were corrected for salt content following the approach provided with the SBE63 Manual revision 010. CO2 measurements were made with a LI-COR LI850 non-dispersive infrared detector housed with the SuperCO2 system. Standardization of the CO2 measurements was achieved through the measurement of four gas standards (Linde; 98.83 ppm, 386.30 ppm, 469.69 ppm, and 1248.45 ppm) that had undergone re-calibration using a zero (N2) and span gas (ESRL; 1567.44 ppm) bracketing the gas standard concentrations. A standardization sequence (measurement of each gas standard sequentially for a period of 90 seconds) was conducted every 4 or 12 hours (over different periods of the data record) and included a 90-second measurement period of atmospheric CO2 partial pressure on air drawn to the system from an intake on the aft deck. The final 20 seconds of atmospheric measurements were retained in the final dataset. Position and weather information (from an Airmax 120WX Weatherstation instrument positioned above the bridge) were logged separately from the SuperCO2 system data, and then merged with the SuperCO2 system data by time-matching the position and weather data to the SuperCO2 system data. This project was supported by the Tula Foundation and Seaspan.
