   The Lake Mendota Microbial Observatory collects routine water physical and chemical measurements alongside their microbial samples. This dataset includes measurements of water temperature, dissolved oxygen, pH, and conductivity collected at the central Deep Hole, collocated with a weather buoy (43°05'58.2"N 89°24'16.2"W). All measurements were collected with handheld probes. Data from 2006-2014 was compiled from multiple sources and includes only water temperature and dissolved oxygen. Data from 2014-2019 is from the same probe, a YSI Pro Plus instrument, and also includes pH and specific conductance. Routine microbial observatory sampling continues into the present.

4. Supplementary discrete sample measurements of dissolved oxygen, dissolved inorganic carbon, and total alkalinity from Ocean Observatories Initiative (OOI) cruises to the Irminger Sea Array 2018-2019

   Palevsky, Hilary I.; Fogaren, Kristen E.; Nicholson, David P.; Yoder, Meg; Yoder, Meg; Palevsky, Hilary I. (January 2023, Biological and Chemical Oceanography Data Management Office (BCO-DMO))

   This dataset contains discrete sample measurements of dissolved oxygen, dissolved inorganic carbon, and total alkalinity collected during yearly Ocean Observatories Initiative (OOI) turn-around cruises to maintain the Irminger Sea Array (60.46°N, 38.44°W). Samples in this dataset were collected as part of an ancillary research project that joined the OOI turn-around cruises in June 2018 and August 2019 as part of ongoing efforts to enable OOI biogeochemical sensor data to be used to address scientific questions about ocean carbon cycling and the biological carbon pump. Discrete sample data collected and analyzed by this research team complement data collected by the OOI program as part of routine turn-around cruise activities. We provide the supplementary measurements made by our team alongside salinity- and oxygen- calibrated Conductivity Temperature Depth (CTD) and oxygen sensor data from the depths where Niskin bottles were closed for sample collection and additional discrete oxygen measurements made by the OOI team.

5. Carbonate chemistry in Mission Aransas Estuary from May 2014 to Feb 2017 and Dec 2018 to Feb 2020

   https://doi.org/10.26008/1912/bco-dmo.835227.1  

   McCutcheon, Melissa R.; Hu, Xinping (January 2021, Biological and Chemical Oceanography Data Management Office (BCO-DMO))

   The Ecosystem Science and Modeling lab has been collecting water samples from five stations in the Mission-Aransas Estuary (MAE, Northwest Gulf of Mexico, Texas coast) for carbonate system characterization on a monthly to twice monthly basis since May 2014. This dataset includes temperature, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), calcium, and pH measurements from surface and bottom water samples in MAE from May 2014 – Feb 2017 and Dec 2018 – Feb 2020. Additional data for this estuary to fill in the Feb 2017 – Dec 2018 gap are also archived with BCO-DMO (http://www.bco-dmo.org/dataset/784673, doi:10.1575/1912/bco-dmo.784673.1).
