Ovenbird song recordings from Alberta (Canada) with individual labels and spatial locations, 2015-2016
This dataset includes spatially localized and individually identified Ovenbird songs. We used automated species detection and acoustic localization to localize Ovenbird singing events from microphone arrays in Alberta, Canada (2015-2016). We then hand-annotated songs to individuals based on acoustic characteristics. This dataset includes the manual annotations and annotations from automated individual identification approaches. This data publication pertains to the manuscript [in prep] by Lapp et al on Ovenbird individual identification and provides further details on the study and the individual identification approach.
Ground-truthing of satellite imagery to track harmful algal blooms in Pigeon Lake, Alberta, Canada 2017-2022
This data was collected to create a calibrated model that would enable the use of satellite imagery to track harmful algal blooms by using chlorophyll a estimates as a proxy for cyanobacteria in the lake. Samples from Pigeon Lake were collected on the same day that the Sentinel-2 satellite would pass over the lake. These samples were analyzed for different algal pigments and enumerated to genus level to ensure that the satellite imagery was of cyanobacteria rather than different algal groups. An algorithm was developed which we termed the three band index (TBI) that best matched with the cholorophyll a from the in situ samples. This model was used on satellite imagery from 2017-2022 of Pigeon Lake to get chlorophyll a estimates for every 20 x 20 pixel of each image of the lake. This pixel data was used to determine different bloom metrics like the intensity, the area (extent) and severity.
Long-term monitoring of peatlands located near oil sands mining activities surrounding Fort McMurray, Alberta, Canada (2009-Present)
Oil sands mining activities in the Fort McMurray region of Alberta, Canada, have led to increased atmospherically deposited nitrogen (N) and sulfur (S), with N steadily increasing over time and S peaking in 2009, then decreasing with the installation of scrubbers on upgrader stacks. Ecosystems (such as ombrotrophic bogs) near these mining activities see an increase to their depositional load. These peatlands are isolated from groundwater and receive inputs only from precipitation, making them uniquely susceptible to changing depositional scenarios. To evaluate the effect of oil sands development on bogs in this area, since 2009, we have collected and analyzed porewater (pH, conductivity, NH 4 + -N, NO 3 - -N, SO 4 2- -S, and total dissolved N), N and S as represented in extractions of ion exchange resin precipitation collectors (NH 4 + -N, NO 3 - -N, SO 4 2- -S), samples of new growth from the most dominant plant species (C, N, and S, with Ca, Mg, K, and P analyzed in later years), and have recorded annual growth of vegetation. For a majority of the years, we have sampled at least 3 times (June, July, and August). Some sites have burned and have been replaced by others, however, collections are on-going and data from these collections are uploaded as they are published.

Methane and carbon dioxide fluxes from vegetated and open water zones of lakes in the Peace-Athabasca Delta, Alberta, Canada, 2019
Shallow areas of lakes, known as littoral zones, emit disproportionately more methane than open water but are sometimes ignored in upscaled estimates of lake greenhouse gas emissions. Littoral zone coverage may be estimated through synthetic aperture radar (SAR) mapping of emergent aquatic vegetation, which only grows in water less than ~1.5 m deep. In an accompanying publication, we combine airborne SAR mapping with field measurements of littoral and open-water methane flux to assess the importance of littoral zones to landscape-scale methane emissions. This dataset contains the field measurements of chamber methane flux from vegetated littoral zones and open water used for the accompanying publication. Measurements come from 24 distinct sampling events of 15 lakes in the Peace-Athabasca Delta, Alberta, Canada in July through August, 2019. The dataset also includes within-lake locations, carbon dioxide measurements, simple characterizations of vegetation type, and associated limnological and meteorological measurements, when available: water and air temperature, water depth, wind speed and direction, and relative humidity.
Alberta Bog Net Nitrogen Mineralization, 2013-2015
Alberta bogs are subject to periodic wildfire. Although these bogs have persisted under low atmospheric nitrogen deposition (less than 2 kg N/ha/yr), nitrogen deposition in northern Alberta is increasing due to ongoing oil sands development. This study examined how time since fire and experimental N deposition affects nitrogen mineralization in near-surface bog peat. Net nitrogen mineralization (ammonification, nitrification, dissolved organic N production) was quantified using the buried bag technique in 5 Alberta bogs differing in time since fire. At each site, 24 2.4 _ 4.8 m plots were established, with 6 replicate plots receiving one of four N addition treatments: controls (receiving no water or N), H2O controls (receiving water, but no N; 0 kg N ha-1 yr-1), and 10 and 20 kg N ha-1 yr-1, applied as NH4NO3 dissolved in 15 L of H2O and applied via backpack sprayer eight times during each summer field season. We established plots and began N additions in 2011 at the Utikuma Bog site and in 2013 for the other four sites. This study is published as: Stuart JEM, Wieder RK, Vile MA (2018) Net Nitrogen Mineralization in Alberta Bog Peat is Insensitive to Experimentally Increased Nitrogen Deposition and Time Since Wildfire.

Introgression between Sphyrapicus nuchalis and S. varius sapsuckers in a hybrid zone in west-central Alberta
<p>Studying species interactions at hybrid zones allows biologists to understand the forces that promote speciation. Hybridization among <i>Sphyrapicus nuchalis</i>, <i>S. varius</i>, and <i>S. ruber</i> has long been acknowledged, and hybrid zones between <i>S. nuchalis/S. ruber</i> and <i>S. varius/S. ruber</i> have been characterized with both genetic and genomic data. Using a combination of next-generation Restriction Site-Associated DNA sequencing (RAD-Seq) and traditional genetic methods, we examined patterns of introgression in the poorly characterized <i>S. nuchalis/S. varius</i> contact zone; the two most similar species in the complex, though they are not each other's closest relatives. We found high introgression rates, with several early and many advanced generation hybrids along a 275 km stretch of Rocky Mountain foothill, pointing to a well-established hybrid zone with hybrid individuals backcrossing with individuals from the parental species and each other. Plumage colouration in the hybrid zone was a relatively poor indicator of parental or hybrid status, which could be attributed to the possible involvement of few large effect genes.</p>

This data was analyzed and presented in the paper "Using a Differential Magneoter Measurement to Infer Geomagnetically Induced Currents: An Augmented Approach." Specifically, these datasets were used to create Figures 3, 4, 5, 6, 7, 9 and 10 in this paper.</p> <p>The data files available here are from two magnetometers (USB4 and USB5) on a magnetically quiet day, September 26th, 2021, and a magnetically active day, October, 12th, 2021. USB4 data is from the underline sensor and USB5 is from the remote sensor. Each DMM data file includes the time in UT and magnetic field measurements in the x, y, and z components, where Bx is magnetic north and By is magnetic east. The GIC data file includes the local time (Mountain Daylight Time = GMT-6) and the transformer neutral-to-ground current at the Ellerslie substation (89S) in both transformers (T1 and T2) during the magnetic storm on October 12th, 2021. The magnetic data has a resolution of 1 Hz. The GIC data has a resolution of 0.5 Hz. </p>

Purgatorius sp., UALVP 51021, left M2, from Medicine Hat Brick and Tile Quarry, Rav W−1 horizon, Ravenscrag Formation, early Puercan (early Paleocene) (Johnston and Fox 1984; Fox and Scott in press), Saskatchewan, Canada, in occlusal (A1), lingually oblique (A2), anterior (A3), and posterior (A4) views. B. Phenacolemur sp.
