ABSTRACT:

In this study conducted by Kathryn Eilers, distributions of Bacteria and Archaea were conducted within Upper and Lower Gordon Gulch. The purpose of this study is to discover how the distributions are related to slope aspect, vegetation type, and edaphic factors.

Sampling was conducted along five transects approximately 200m (transects 1, 2, 3, 6 and 7), 400m (transects 8, 9, and 10), or 600m (transects 4 and 5) in length in the two regions of the watershed (see Overview Map) with samples collected from twenty, regularly spaced points (10 m, 20 m, or 30 m apart) along each transect. Each sample consisted of twenty, 0-5 cm cores, taken within a one meter radius, that were homogenized and sieved to 2 mm. Samples were then stored at 40C and split for analysis within two days of collection. Samples used for soil microbial community analysis were frozen at -800C until DNA was extracted.

ABSTRACT:

In this study conducted by Patrick Kelly, shallow subsurface rock samples were drilled at 9 sites in Lower Gordon Gulch. The coupled geotechnical and quantitative geochemical tests was used to elucidate:

1. Links between geochemical and mineralogical changes and mechanical strength reduction in the shallow subsurface.

2. Systematic spatial and environmental differences between weathering products and mechanical strength.

3. Links between regolith cover and the mechanical strength of weathered rocks.

ABSTRACT:

In the recent years, particularly since the 2002 drought, the presence of Didymosphenia Geminata have significantly increased in Colorado mountain streams. Didymosphenia geminata is a nuisance algal species also known as 'didymo' or 'rock snot'. Didymo can coat streambeds as a thick brown algal mat, with mats as thick as 1-2cm.

A study was conducted along Boulder Creek from 2008-2010 to investigate factors affecting the removal of D. geminta. Samples of D. geminata were collected at various points Boulder Creek between June 2008 and September 2010. Metrics for measuring didymo growth includes Didymo Rating Index (DRI), ash-free-dry-mass(AFDM), chlorophyll concentration and didymo cell densities. Didymo Rating Index(DRI) is a qualitative way to gauge didymo growth. It ranges from 0, representing no obvious signs of didymo growth, to a maximum of 10, representing 100% coverage and mats greater than 5 cm thick. The maximum DRI for Boulder Creek was a 6 or 7 (100% coverage with a mat thickness of 1 to 2cm).

Results of the study show the importance of taking into account site specific geomorphologic controls such as the potential for bed disturbance in addition to simple hydrologic controls such as variations in discharge. The results also show the importance of considering different controls for individual processes such distinguishing between the drivers of increased cell division or increased mat production in understanding the dynamics of complex ecological systems such as that presented by D. geminata.

ABSTRACT:

This data release consists of Digital Elevation Models (DEM's) and LAS-formated point cloud tiles derived from a snow-on (May, 2010) and snow-off (August, 2010) LiDAR (Light Detection and Ranging) survey inside the Boulder Creek Critical Zone Observatory (CZO), near Boulder Colorado. This data was collected in collaboration between the Boulder Creek CZO and the National Center for Airborne Laser Mapping (NCALM), both funded by the National Science Foundation (NSF). Together, the LiDAR Digital Elevation Models (DEM) and point cloud data will be of interest to land managers, scientists, and others for study of topography, snow, ecosystems and environmental change. The Boulder Creek CZO will be using the LiDAR data to further their mission of focusing on how water, atmosphere, ecosystems, & soils interact and shape the Earth's surface. The 'Critical Zone' lies between rock and sky. It is essential to life - including human food production - and helps drive Earth's carbon cycle, climate change, stream runoff, and water quality.

ABSTRACT:

LiDAR was acquired for a 600 km2 area inside the Boulder Creek watershed during a snow-off (August, 2010) time slice, near Boulder Colorado. This data was collected in collaboration between the National Center for Airborne Laser Mapping (NCALM) project and the Boulder Creek Critical Zone Observatory (CZO), both funded by the National Science Foundation (NSF). The dataset contains 1 m Digital Surface Models (first-stop), Digital Terrain Models (bare-earth), and 10 points/m2 LAS-formated point cloud tiles. The DSMs and DTMs are available in GeoTIFF format, approx. 1-2 GB each, with associated shaded relief models, for a total of 15 GB of data. The Digital Terrain Model (DTM) is a ground-surface elevation dataset better suited for derived layers such as slope angle, aspect, and contours. Accessory layers consist of index map layers for point cloud tiles, DEM extent, and flight lines. Other LiDAR DSMs, DTMs, and point cloud data available in this series include snow-on data for 2010.

ABSTRACT:

Climatological data were collected from a ridgetop climate station east of Niwot Ridge (B1 at 2591 m) throughout the year using an Omnidata DP219 datapod. This instrument has a sample interval of 10 minutes and maximum and minimum values are instantaneously recorded. Averages are means of 144 values and totals are totals of 144 values. Parameters measured were evapotranspiration, solar radiation, maximum temperature, minimum temperature, and mean temperature.

ABSTRACT:

Precipitation data were collected from a ridgetop climate station East of Niwot Ridge (B1 at 2591 m) throughout the year using a chart recorder. Initially, instrumentation consisted of an 8-inch metal rain gauge with receiving rim about 3 feet off the ground and measurements were made on approximately weekly basis. More recently, instrumentation consisted of a Fegusson type weighing rain gage. Precipitation was caught in a bucket containing ethylene glycol (to melt snow) and light oil (to prevent evaporation). Asthe weight of the bucket increased, the pen moved up via a spring mechanism and recordedona rotating chart. Precipitation was recorded on a continuous basis.

ABSTRACT:

Climatological data were collected from a ridgetop climate station East of Niwot Ridge (B1 at 2591 m) throughout the year using a Hobo Pro V2 data logger mounted in a Stevenson screen. Parameters measured were air temperature and relative humidity

ABSTRACT:

This is a meterological tripod collecting climate data on a ten minute interval. It is located on a ridgetop East of Niwot Ridge at an altitude of 2591 meters. It is located in a clearing surround by a low-density montane forest, consisting of mostly lodgepole and ponderosa pine. The datalogger records values on a ten minute inteval. The parameters measured include air temperature, wind speed/direction, snow depth, precipitation, net radiation, soil moisture, soil electrical conductivity, and soil volumetric water content. This met station was installed to bring the historic B1 site up to date with modern instrumentation. B1 has climate records dating back to the 1950s, and this met station will provide an ongoing comparison for historical datasets. Additionally, B1 is a part of a network of sites along an elevational gradient from the foothills up to the continental divide. This site has been maintained by Boulder Creek CZO with collaboration from Niwot LTER.

ABSTRACT:

A series of slug tests were performed at groundwater monitoring wells in upper Gordon Gulch. The spefic wells tested were GGU_GW1, GGU_GW2, GGU_GW3, GGU_GW4, GGU_GW5, and GGU_GW6. Slug tests were perfomed by Steven Henning, a master's candidate at CU Boulder. Tests were performed on 8/6-7/2015 and 9/12-13/015. The tests were perfomed to determine the hydraulic conductivity of the aquifer material around the monitoring wells.

ABSTRACT:

These data accompany the analysis of regolith weathering across ~940 km2 of the Front Range (Colorado, USA) described by Dethier & Lazarus (2006).

Collected data from 1872 paper records of well-drillers' logs held on file at the Colorado Department of Water Resources (Denver office). We used every interpretable record from the Allens Park, Eldorado Springs, Gold Hill, Nederland, Tungsten, and Ward quadrangles. We recorded the thickness of overburden, alluvium, and highly weathered regolith, along with the total weathered thickness, depth to fresh bedrock, total well depth, and any drillers’ notes. We then digitized well locations (and their associated data) on topographic quadrangles in ESRI ArcMap. The maximum probable location error for any well in the dataset is the area of a 1/16 section (approximately 0.16 km2). See Dethier & Lazarus (2016) a detailed description of the methods.
