  • Beaufort Gyre Observing System (BGOS) Underway Partial pressure of carbon dioxide (pCO2) data and air-sea CO2 fluxes, Arctic Ocean, 2011-2021
Title: Beaufort Gyre Observing System (BGOS) Underway Partial pressure of carbon dioxide (pCO2) data and air-sea CO2 fluxes, Arctic Ocean, 2011-2021
These data were collected on the CCGS (Canadian Coast Guard) Louis St. Laurent during BGOS (Beaufort Gyre Observing System) research cruises in 2012-2014 and 2016-2021 in the Beaufort Sea area. They are underway pCO2 (Partial pressure of carbon dioxide) data collected using an equilibrator-infrared method (SUPER CO2 system from Sunburst Sensors). Ancillary data for calculation of air-sea CO fluxes include temperature, salinity, atmospheric CO2, wind speed, and gas transfer velocity (calculated from Wanninkhof et al. (2009). Fluxes are not corrected for fractional ice-coverage. The specific goal of the study is to continue to operate an Arctic Observing Network (AON) for the measurement of the partial pressure of CO2 (pCO2), pH, and dissolved O2 (DO) focused on the surface waters of the Arctic Ocean (specifically, the Canada Basin). These data were collected on the CCGS (Canadian Coast Guard) Louis St. Laurent during a BGOS (Beaufort Gyre Observing System) research cruise in the Beaufort Sea area.

    The goal of the proposed study is to establish an Arctic Observing Network (AON) for sea surface partial pressure of carbon dioxide (pCO2) and pH in the perennially ice-covered portion of the Arctic Ocean. The carbon cycle is of particular concern in the Arctic because it is unknown how carbon sources and sinks will change in response to warming and the reduction of summer sea ice cover, and whether these changes will lead to increased greenhouse gas accumulation in the atmosphere. Furthermore, the penetration of anthropogenic caron dioxide (CO2) into the Arctic Ocean is leading to acidification with potentially serious consequences for organisms. Little is known about pCO2 and the inorganic carbon cycle in the central Arctic Ocean because most measurement programs to date have focused on the Arctic shelves during the accessible summer period. The investigators propose to use an existing component of the Arctic Observing Network, the Ice-Tethered Profilers (ITP), as platforms for deployment of in situ pCO2 and pH sensors. ITPs are automated profiling systems distributed throughout the perennial Arctic ice pack that telemeter data back to shore: 44 ITPs have been deployed since 2004 and the project is currently slated to continue through 2013. In the proposed work, a total of 6 ITPs will be equipped with CO2 sensors and four of these will also have pH sensors. The sensors will be fixed on the ITP cable ~2-4 meters below the ice. Each unit will include additional sensors for dissolved O2, salinity, and photosynthetically available radiation (and in some cases chlorophyll-a fluorescence) and will be capable of making 12 measurements per day for at least one year. These data, available in near real-time on the ITP web site (www.whoi.edu/itp/), will lead to a better understanding of the Arctic Ocean's role in regulating greenhouse gases and how the ecology of the Arctic will change with warming and acidification. The investigators will also engage in outreach programs including public presentations, podcasts, and school visits. A portion of the budget is also dedicated to the development of a climate-change/ocean acidification exhibit to be displayed in the University of Montana's science museum. The exhibit will reside at the museum for three months, then visit over 15 rural and tribal communities annually over a three year period. Undergraduate students will be recruited to assist with the sensor testing and data analysis, gaining a higher level of technical knowledge than possible through a traditional degree program. These data were collected using in situ sensors for the partial pressure of CO2 (pCO2), pH, dissolved oxygen (DO), photosynthetically available radiation (PAR), temperature, salinity and depth. Sensors were deployed at ~6 meter depth on ice-tethered profilers, in collaboration with Woods Hole Oceanographic Institution (Rick Krishfield and John Toole). Data are available at the website http://www.whoi.edu/page.do?pid=20781.

    This data file contains dissolved O2/Ar saturation ratio measured from the surface uncontaminated seawater system on the US Coast Guard Cutter (USCGC) Healy while transiting from Seward, Alaska USA to Nuuk, Greenland via the Northwest Passage. Data were collected in the Bering, Chukchi, Beaufort Seas, the Canadian Arctic Archipelago, and Baffin Bay (see map). The data are useful for understanding the balance of physical and biological controls driving surface ocean dissolved O2 concentrations and for calculating net biological community production rates. The data were collected with funding from NSF Award 1928684 “High Resolution Observing of Arctic Net Community Productivity with Ships of Opportunity” Data were collected between August 27th, 2021 and September 12th, 2021 from the surface uncontaminated seawater supply of USCGC Healy on Cruise ID HLY21TD. Data were collected near-continuously using an equilibrated inlet mass spectrometer (EIMS), with occasional outages for instrument maintenance or flow disruptions.

    These data files contain surface dissolved O2 concentration and dissolved O2/N2 saturation ratio for the Bering, Chukchi, and Beaufort Seas with relevant accompanying ancillary information. The data are useful for understanding the balance of physical and biological controls driving surface ocean dissolved O2 concentrations and for calculating net biological community production rates. The data were collected with funding from NSF Award 1928684 “High Resolution Observing of Arctic Net Community Productivity with Ships of Opportunity.” These data are being disseminated to the research community with limited processing; an updated version with enhanced data quality control may be available in the future. Please contact the PI, Laurie Juranek (laurie.juranek@oregonstate.edu) for questions about use. Data were collected between July 31st and December 3rd, 2022 from the surface underway seawater supply of R/V Sikuliaq on several cruises. Data were collected using a Pro-Oceanus miniTDGP (total dissolved gas pressure instrument), a SBE38 temperature sensor, a SBE45 thermosalinograph, and an Aanderaa 4330 dissolved O2 optode, with occasional outages for instrument maintenance or flow disruptions. Sea level pressure data from a Vaisala PTU307 are also provided.
