Data Questions? Data Help Desk has the Answers

Cross-posted from the ESA website ESA conference attendees brought many inquiries about data issues, needs, and planning strategies to the ESA/USSEE 2019 Data Help Desk. Representatives from seven data-intensive organizations (Table 1) shared their collective expertise and insights with more than 200 booth visitors. Collectively, we made an impressive presence of data organizations in the exhibition and… Read more »

Learning from the Hunters in Savoonga, with Dr. Henry Huntington

Highlight: “The hunters have a lot of valuable information to share, but often this information is overlooked or regarded as too difficult and time consuming to document. We’re helping show that’s not the case, that there are proven methods for documenting Indigenous knowledge efficiently and sharing that information,” – Dr. Henry Huntington. This dataset is… Read more »

Exploring the Energy, Clouds, Atmosphere and Precipitation in Summit, Greenland, through ICECAPS, with Dr. Matthew Shupe

Highlight: “ICECAPS data and analyses have developed process relationships that relate cloud variability to different terms of the surface energy budget as a function of time of year. These relationships are used to assess large-scale models and identify specific model deficiencies that must be addressed to accurately represent the energy partitioning at Greenland’s surface,” –… Read more »

Phenological Mismatch in the Arctic, with Dr. Kathy Kelsey

Highlight: “These data are critical for understanding how climate-induced changes in the timing of migratory herbivore grazing should be included in projections of the role of Arctic and Subarctic ecosystems in the global climate system,” – Dr. Kathy Kelsey. Phenological mismatch is when the timing of food and/or habitat availability for a species is altered… Read more »

Investigating Rotten Ice, with Dr. Karen Junge

Highlight: “So-called rotten ice has experienced a long summer of melt, is fragile, difficult to work with, and has received little attention. Comprehensive information on its physical and microbiological properties does not exist,” – Dr. Karen Junge. Decreases in ice extent, concentration, and thickness have all been observed in the Arctic as sea ice responds… Read more »

  Highlight: “It is our goal to accurately describe contemporary subsistence activities and the issues faced by Arctic communities, all in support of sustaining these communities into the future,” – Dr. James Fall. This dataset, part of the same Bering Sea Integrated Research Program as a previous dataset highlight, investigates the implications of climate change… Read more »

Dissolved Organic Carbon, with Dr. Rose Cory

Rose Cory

Highlight: This dataset is behind the study recently highlighted in a High Country News article, sharing the work of Dr. Rose Cory and her team. This dataset is part of a project working to understand what happens to soil organic matter when it’s flushed from soils to streams, ponds and lakes. This organic carbon is… Read more »

Data Provenance and Arctic Soil Bacteria with Michael P. Ricketts

View from Toolik Field Station, Alaska

Highlight: This dataset makes use of the Arctic Data Center’s data provenance tool to show the relationships between different data inputs and the processing that lead author Michael P. Ricketts and his team used to perform their analysis. By doing this, Ricketts is ensuring that this research is reproducible by others. This dataset is part… Read more »
