This data release presents data that were collected as part of a larger effort to assess factors that regulate ecosystem metabolism in small ponds. This work was part of an international collaborative effort with the Global Lake Ecological Observatory Network (GLEON). From May to October 2019, dissolved oxygen, temperature, and light were measured throughout the water-depth profile of two natural wetlands and four artificial ponds located near Jamestown, North Dakota. Meteorological and bathymetric data also were collected. The natural wetlands are representative of semipermanent wetlands of the Prairie Pothole Region of North America. The artificial ponds, while smaller than the natural ponds, were managed to represent small inland wetlands of the Prairie Pothole Region. The Artificial ponds are managed by the U.S. Geological Survey Northern Prairie Wildlife Research Center. Data from this collaborative study will be used to understand how small inland ponds differ from large lakes and coastal systems, specifically with regard to nutrient recycling, primary production, greenhouse gas emissions, and oxygen dynamics.

This data release presents data that were collected as part of a larger effort to assess factors that regulate metabolism in global lakes, via an international collaboration with the Global Lake Ecological Observatory Network (GLEON). From May to August 2019, dissolved oxygen and light penetration were measured throughout the water-depth profile of two small inland wetlands at Cottonwood Lake Study Area in North Dakota, USA. Water temperature and wind data also were collected, and recent water column chemistry (carbon, phosphorus, nitrogen) data from the summer of 2016 were compiled. Data from this collaborative study will be used to calculate gross primary production, and investigate how lake metabolism varies with lake size, light availability, and carbon and nutrient concentrations.

A study was conducted to assess the relationships among carbon mineralization, sulfate reduction and greenhouse gas emissions in prairie pothole wetlands. These data are for dissolved methane and carbon dioxide concentrations and fluxes. Dissolved gas concentrations in the water column and fluxes to the atmosphere were estimated from April through November, 2015 for wetlands P7 and P8 of the Cottonwood Lake Study area, Stutsman County, North Dakota. Dissolved gases in the water column were collected every two weeks using a pumping-induced ebullition device. Gas flux samples were collected concurrently at the water-atmosphere interface using the vented static-chamber method. Gas concentrations of the gas samples were determined using gas chromatography. Air and water temperature and water depth also were collected concurrently. These data directly support the associated publication “Abundant carbon substrates drive extremely high sulfate reduction rates and methane fluxes in Prairie Pothole Wetlands” which is referenced within the Metadata.

This release contains data collected to study the impacts of vegetation removal on the condition of Lake Ozette Sockeye spawning habitat. From October 2018 to May 2019, continuous sediment temperature and subsurface dissolved oxygen were collected at sites near Olsen's Beach on the eastern shore of Lake Ozette, WA. Data were collected from 3 sites; a spawning control (SC) where sockeye currently return to spawn; a vegetation control (VC) where nearshore vegetation inhibits the amount of sockeye spawning; and a vegetation treatment (TR) area where nearshore vegetation was manually removed to assess if habitat quality can be improved. In addition to the continuous data, particle size data from the nearshore were determined at the beginning (October 2018) and end (May 2019) of the study period. Details of data collection methods and data quality, are available in three child items (1) Estimates of groundwater flux from vertical temperature profiles within lakebed sediments at Lake Ozette, WA, October 2018 to April 2019, (2) Nearshore lake sediment particle-size distribution data, Lake Ozette, WA, October 2018 and May 2019, and (3) Subsurface dissolved oxygen and sediment temperature at Lake Ozette, WA, October 2018 to May 2019.
