Landsat subpixel water cover of Lena River Delta, Siberia, with link to ESRI grid files
No full textLandsat data for Samoylov Island (Lena Delta, Siberia) was classified using a k-means unsupervised algorithm in the ENVI 4.7 software. Unsupervised classifications are based solely on the natural groupings within the image, i.e. the spectral properties of the surface, and as such return classes containing spectrally similar pixels. The resulting satellite spectral classification was compared with the aerial land cover classification in order to assess the fine-scale land cover variability within each satellite pixel and k-means class. Classification of was performed with 15 clusters and 15 iterations. The 15 clusters were reduced to 9 groups by merging clusters with little pixel count into spectrally adjacent classes. k-means classification of Landsat pixels is determined by the proportions of open water and dry tundra within each pixel. Class 1 is a water class. Classes 2-9 are characterized by a gradual decrease in open water and an increase in dry tundra.
The entire Lena Delta was then classified using an atmospherically corrected Landsat mosaic (Schneider et al., 2009, doi:10.1016/j.rse.2008.10.013). Schneider et al. (2009) identified nine land cover classes for the Lena Delta, five of which are present in the ice-wedge polygonal tundra on Samoylov Island. We therefore performed classification for these five classes only, which together make up 70% of the total land area in the Lena Delta. The Landsat mosaic consists of three images with a resolution of 30 m, acquired on July 27, 2000 (featuring Samoylov Island), and July 26, 2001. Bands 1-5 and band 7 were used for classification covering a spectral range in the VNIR and short-wave infrared (SWIR) from 450 to 2350 nm.
Some 13% of the delta's land surface (not including rivers and coastal areas) has been estimated from Landsat data to be occupied by water bodies (Schneider et al. 2009). Including the subpixel-scale land/water fraction, the water surface area increases to 20%.
Data is available as raster (ESRI bil). Data includes an ArcGIS layer file showing the mean ratio of open water per pixel and class. Class 10 (Lena river and coastal zones) was not included in the original classification of the Delta, but was added to the dataset for better visual aid.

Interpretation and performance of three orchestral compositions by Gabriela Lena Frank: Escaramuza, Elegia Andian, and Three Latin American Dances
No full textThis work presents interpretative and performance suggestions for three of Gabriela Lena Frank’s orchestral works: Escaramuza (2010), Elegia Andina (2000), and Three Latin American Dances (2004). Frank’s compositions frequently include programmatic elements that reference other well-known compositions, and she incorporates melodies, rhythms, timbres, instrumentation, and performance techniques characteristic of her Peruvian cultural heritage. Examples of these elements are presented from a lecture recital format to demonstrate how performance practice and conducting decisions—in rehearsal and performance—can be utilized to honor the composer’s expressed intent and overcome various technical ensemble and conducting challenges. An overview of the cultural contextual elements includes Harawi and Kachampa dance structures. The author also suggests methods for presenting elements that affect the timbre and instrumental scoring specific to each work, for example the Andean Zampoña. This research provides performers with a resource to deepen their score study, and seeks to inspire more people to perform the music of Gabriela Lena Frank.D. A
Methane production and storage in the Lena river delta during winter 2011
No full textMeasured methane concentrations in the ice cover of ponds and lakes on Samoylov Island (Lena-River-Delta in northern Siberia). Methane concentration were extracted from ice core samples. The location of each sample relative to the lake surface is indicated by a minimum and maximum depth. The ice cores were extracted by cutting ice columns to a depth of about 70 cm from the ice cover. The ice samples were melted in 1 L plastic containers. Methan concentration were obtained by head-space analysis. For a detailed description of the methods see Langer et al. (2015)

(Table 2) In situ measured ice thickness, snow depth and water depth in April 2015 at 14 locations on 10 lakes in the Lena River Delta, Siberia
No full textIn situ ice thickness measurements were performed with powered hole borer at 14 locations from a sample of 10 lakes in April 2015 in the Lena River Delta, Siberia. Seven of these locations featured grounded ice and the other seven floating ice. Additionally, snow depth on the ice surface and water depth beneath the ice cover (if present) were measured
