    The data sets currently supported by the Pilot Climate Data System (PCDS) are listed, many of which are Level II and Level III NImbus-7 data sets. Those data sets planned for future access through the PCDS were also listed, and their current installation status was stated. The tasks involved in supporting data sets within the PCDS were identified and described. After a data set is approved for implementation into the system and communication with the data producers is established, the information for the detailed catalog entry is gathered. This information then is reviewed with the scientists involved before producing a catalog summary. Once this is done, the catalog information can be provided to users, even before the data set is installed. The next several tasks involve software development and can prove to be the most time-consuming aspect in the data set support. These tasks can be simplified if the data producers provide complete and accurate documentation of their product. Software for reading and interpreting the data sets is developed and the data sets, or portions therefore, that will be made available for use within the PCDS are inventoried. Users can access this information via the INVENTORY Subsystem of the PCDS

    Seabird and Plastic Ingestion Data Set

    Plastic debris is a pervasive and critical environmental challenge that is being described as a world-wide crisis for marine life. Seabirds are sensitive to pollutants and are of critical conservation concern. Because seabirds are excellent bioindicators of marine ecosystem health, information about their plastic ingestion can serve as an indicator of plastic exposure across multiple marine trophic levels. Our study describes the prevalence of plastic ingestion for four seabird species: Great Black-backed Gulls (Larus marinus), Herring Gulls (L. argentatus), Common Terns (Sterna hirundo), and Roseate Terns (S. dougallii) nesting in the Gulf of Maine. Samples were collected opportunistically, including pellets, regurgitant, discarded fish, and deceased seabirds. Plastics were primarily found in pellet samples, and common types included fragments and sheets. Herring Gulls displayed significantly higher plastic exposure than the other three species across all metrics analyzed (p-valu

    DIY Human Action Data Set Generation

    The recent successes in applying deep learning techniques to solve standard computer vision problems has aspired researchers to propose new computer vision problems in different domains. As previously established in the field, training data itself plays a significant role in the machine learning process, especially deep learning approaches which are data hungry. In order to solve each new problem and get a decent performance, a large amount of data needs to be captured which may in many cases pose logistical difficulties. Therefore, the ability to generate de novo data or expand an existing data set, however small, in order to satisfy data requirement of current networks may be invaluable. Herein, we introduce a novel way to partition an action video clip into action, subject and context. Each part is manipulated separately and reassembled with our proposed video generation technique. Furthermore, our novel human skeleton trajectory generation along with our proposed video generation technique, enables us to generate unlimited action recognition training data. These techniques enables us to generate video action clips from an small set without costly and time-consuming data acquisition. Lastly, we prove through extensive set of experiments on two small human action recognition data sets, that this new data generation technique can improve the performance of current action recognition neural nets
