Brian Tangen
Brian Tangen is an Ecologist with the USGS Northern Prairie Wildlife Research Center and works at the Lincoln, Nebraska duty station.
I began my professional career processing and identifying aquatic invertebrates and conducting a wide variety of field work for Northern Prairie's aquatics lab. I have worked in a variety of roles at Northern Prairie performing research focused on carbon and greenhouse gas cycling in wetland systems, wetland hydrology, wetland management, and effects of climate- and land-use change.

Dissolved oxygen, temperature, and light measured along the water-depth profile of wetlands in North Dakota, USA, 2019 Dissolved oxygen, temperature, and light measured along the water-depth profile of wetlands in North Dakota, USA, 2019
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...
Properties of ice cores from Hobart Lake, North Dakota, USA, 2021 Properties of ice cores from Hobart Lake, North Dakota, USA, 2021
This data release presents data that were collected as part of a larger effort (Global Lake Ecological Observatory Network [GLEON] IceBlitz) to enhance understanding of the spatial and temporal variation in global lake ice properties. During January and February of 2021 ice cores were extracted from Hobart Lake, North Dakota, USA and characterized following standard procedures...
Carbon dioxide flux, vegetation, and soils data from artificial ponds in North Dakota, USA, 2021 Carbon dioxide flux, vegetation, and soils data from artificial ponds in North Dakota, USA, 2021
This data release presents data that were collected as part of a larger effort to assess the carbon balance of recently exposed (i.e., no vegetation cover) wetland sediments. This work was part of an international collaborative effort associated with the Dryflux II project. During June and July 2021, data were collected from three artificial ponds located near Jamestown, North Dakota, to...

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...
Soil profile characteristics of Prairie Pothole Region wetland catchments, 2004 Soil profile characteristics of Prairie Pothole Region wetland catchments, 2004
A study was conducted during 2004 to examine soil carbon storage of Prairie Pothole Region wetland catchments. These data represent the soil profile descriptions performed during that study; the remaining data were published previously (https://doi.org/10.5066/F7KS6QG2). Soil profile descriptions were performed at 270 temporary, seasonal, and semipermanent wetland catchments distributed...
Genetic and morphologic characteristics of Typha (cattail) taxa of the Prairie Pothole Region of the United States (2018) Genetic and morphologic characteristics of Typha (cattail) taxa of the Prairie Pothole Region of the United States (2018)
Cattail (Typha) is a common plant found throughout the Prairie Pothole Region (PPR) of the United State. Typha x glauca, a hybrid between Typha latifolia and Typha angustifolia, is considered an invasive species that has spread across the PPR, negatively impacting the regions important wetlands and other aquatic habitats. The distribution of the various cattail taxa, however, is not well

Using a vegetation index to assess wetland condition in the Prairie Pothole Region of North America Using a vegetation index to assess wetland condition in the Prairie Pothole Region of North America
Wetlands deliver a suite of ecosystem services to society. Anthropogenic activities, such as wetland drainage, have resulted in considerable wetland loss and degradation, diminishing the intrinsic value of wetland ecosystems worldwide. Protecting remaining wetlands and restoring degraded wetlands are common management practices to preserve and reclaim wetland benefits to society...

Prairie wetlands as sources or sinks of nitrous oxide: Effects of land use and hydrology Prairie wetlands as sources or sinks of nitrous oxide: Effects of land use and hydrology
National and global greenhouse gas (GHG) budgets are continually being refined as data become available. Primary sources of the potent GHG nitrous oxide (N2O) include agricultural soil management and burning of fossil fuels, but comprehensive N2O budgets also incorporate less prominent factors such as wetlands. Freshwater wetland GHG flux estimates, however, have high uncertainty, and...

Land management strategies influence soil organic carbon stocks of prairie potholes of North America Land management strategies influence soil organic carbon stocks of prairie potholes of North America
Soil organic carbon (SOC) stocks of Prairie Pothole Region (PPR) wetlands in the central plains of Canada and the United States are highly variable due to natural variation in biota, soils, climate, hydrology, and topography. Land-use history (cropland, grassland) and land-management practices (drainage, restoration) also affect SOC stocks. We conducted a region-wide assessment of...

Distributions of native and invasive Typha (cattail) throughout the Prairie Pothole Region of North America Distributions of native and invasive Typha (cattail) throughout the Prairie Pothole Region of North America
The Prairie Pothole Region (PPR) of North America has experienced extreme changes in wetland habitat due to proliferation of invasive plants. Typha × glauca is a highly competitive hybrid between native T. latifolia and non-native T. angustifolia, and it is likely the predominant taxon in PPR wetlands. Genetics-based studies are limited, and distributions are poorly known for the first...

Wetlands Wetlands
During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in...

Preserving soil organic carbon in prairie wetlands of central North America Preserving soil organic carbon in prairie wetlands of central North America
Wetlands of the Prairie Pothole Region (PPR) in the Great Plains of central North America are numerous, densely distributed, and have highly productive plant and animal communities (Photo 49). When in a natural, unaltered condition, these wetlands store relatively large amounts of organic carbon in their soils (Photo 50). Human alterations, such as extensive drainage and land-use...
