title: Docker-specific Refactorings & Technical debts

description:  Docker-based containerization has become the standard for modern software deployment, enabling scalable and efficient application management. However, containerized projects, relying on Docker and Docker-Compose configurations, often accumulate technical debt and require systematic refactoring to maintain quality. To facilitate research and industry practices in addressing these challenges, we introduce DockerRefactorDB, a comprehensive dataset containing 1,214 refactoring instances identified across 443 open-source Docker projects. This dataset catalogs 41 Docker-specific refactoring types and 9 categories of technical debt, offering a structured repository of real-world refactoring patterns. DockerRefactorDB provides valuable insights for software engineers, researchers, and tool builders, supporting the development of best practices, automated refactoring tools, and strategies to improve the maintainability of containerized applications.

title: Zooplankton-phasmavirus population genetic and prevalence data in Subarctic ponds, 2011-2015

description: The file contains sequence alignments (population data) of individual phantom midges from permanent ponds, (Chaoborus spp.) and their associated RNA viruses ( Orthophasmaviridae: Kigluaik phantom virus or KIGV, Nome phantom virus or NOMV). The host sequences are from two genes from the mitochondrial genome while the viral sequences are from all four genes in their respective genomes. To preserve annotations, the alignment data files are in the Sequin format (freely available from NCBI). All files are readily converted to the FASTA format within Sequin. 
Virus prevalence data are given for 25 ponds (and a five year window for one site). Also virus screening data (from reverse transcription PCR) for non-midge arctic zooplankters are given. Study ponds (co-ordinates are provided in a file ) are both recent thaw and glacial ponds on the Seward Peninsula, AK, and Baffin Island, Canada.

title: Photogrammetric scans of aerial photographs of North American glaciers, 1984. Roll 1 tiffs

description: Introduction: 
 
 Between 1958 and 1999, Austin Post led the USGS collection of aerial imagery of North American glaciers. These images are primarily vertical stereo black and white images, although single oblique images, as well as color images have been collected. The glaciers of North America were the subjects, and the digital products made available here serve to document the changes that have occurred to the glaciers over the past 5 decades. The purpose of this project is to preserve the data contained within these film images in a digital format for future analysis of North American glacier change.
 
 File Layout: 
 
 
 1. 
 
 The first level contains an overall data set of image metadata from 1964 - 1997 (nagapData.csv) and an R script (searchData.R) with instructions on how to search and subset the data. fileLayout.pdf shows the file structure and folder contents visually. There are also three kml files with flight path information by decade. 
 
 2. 
 
 The second level is the year in which the pictures were taken. There are 32 years with images from 1964 – 1997. The majority of these folders are jpegs with notes provided by Austin Post. They also contain a year-specific csv (YYYY.csv) that contains image metadata for the entire year (date, roll numbers, location name, longitude, latitude, altitude, media, and comments). The overall data set (nagapData.csv) is the aggregate of each individual “YYYY.csv” file. 
 
 3. 
 
 The glacier photos are located at the third level (this level). The folders at this level are distinguished by camera roll number (1, 2, etc.), and image type (thumbnail, jpeg, or tif); some also contain fiducial and oblique image folders. This level primarily contains image files of aerial photos as either thumbnails, jpegs, or tifs. It also includes a csv with image metadata specific to each roll (date, roll numbers, location name, longitude, latitude, altitude, media, and comments), a text file (info.txt) with camera specifications unique to each image, and a text file (histo.txt) with color information unique to each image.

title: An open source framework for metadata exploration and discovery of Polar Data

description: This project will deliver an open source framework for metadata exploration, automatic text mining and information retrieval of polar data that uses the Apache Tika technology. Apache Tika is currently the de facto "babel fish", aiding in the automatic MIME detection, text extraction, and metadata classification of over 1200 data formats. The PI will expand Tika to handle polar data and scientific data formats, making Polar data more easily available, searchable, and retrievable by all major content management systems. The proposed activity will lay the framework for a thorough automatically generated inventory of polar metadata and data. Expanding Tika to handle polar data will also naturally invite the technology/open source community to deal with polar use cases, helping to increase understanding of the arctic. The resultant software produced through effort will be disseminated to the software and polar communities through the Apache Software Foundation. A computer science graduate student and postdoc will be exposed to Cryosphere and Arctic data, helping to train the next generation of cross disciplinary data scientists in the domain. The PI's Search Engines (20-40 students annual enrollment) and Software Architecture (30-50 students annual enrollment) graduate courses at USC will benefit from the Arctic cyberinfrastructure use cases disseminated through course projects and lecture material. The PI will also work collaboratively with NSF-funded projects dealing with projects focusing on the archiving, discovery and access of polar data, such as ACADIS and the Antarctic Master Directory.

title: Spectral Reflectance Measurements NIMS grid Barrow, Alaska 2015

description: Spectral measurements were taken at each meter of the Networked Info-mechanical Systems (NIMS) grid in Barrow, Alaska during the summer of 2015. The NIMS grid is situated about 200 meters to the north east side of the International Tundra Experiment (ITEX) dry sites. Measurements were taken from the edge of each white board located at each meter aimed at the plots. The instrumentation used was a Unispec dual channel (DC) spectrometer with fiber optics as sensors. A manfrotto tri-pod with an arm attachment was used to hold the fibers and sensors in place while taking the spectral measurements. The arm had 2 bubble levels to assist in keeping the sensors as level as possible. The calculated foot print cover is about 50-60 cm using a tripod height of 1.62 meters. The sensor angle for each scan is 20 degrees.

title: Spectral Reflectance Measurements ARCSS grid Barrow, Alaska 2015 _

description: Spectral measurements were taken on a 30 plot subset within the ARCSS grid in Barrow, Alaska during the summer of 2015. Spectral measurements were taken from the north eastern most corner of each plot. The subset is located from D2-D7 &amp; H2-H7 with the 1 km^2 ARCSS grid. The instrumentation used was a Unispec dual channel (DC) spectometer with fiber optics as sensors. A Manfrotto tripod with an arm attachment was used to hold the fibers and sensors in place while taking the spectral measurements. The arm had 2 bubble levels to assist in keeping the sensors as level as possible. The calculated foot print cover is about 50-60 cm using a tripod height of 1.62 meters. The sensor angle for each scan was 20 degrees. Extra reference scans were taken on a 100% reflective white board surface. Some plots contain crosshairs that are used for point framing purposes and might have an effect on the reflectivity of each scan. Therefore, an extra scan was taken adjacent to each plot on the west side.
