ThinkSpatial: Qinghua Ding

On Tuesday, October 2, 2018, The UCSB brown-bag forum on spatial thinking presents Recent Slow Melt of Arctic Summer Sea Ice caused by Tropical SST Changes Qinghua Ding Department of Geography University of California, Santa Barbara 12:00 p.m. Tuesday, October 2, 2018 | 3512 Phelps Hall (map) Flyer Abstract: Arctic sea ice in September, the minimum observed area each year, is very sensitive to global climate variability. Thus, the abrupt decline of this minimum area since the 1980s has been viewed as a “canary in the coalmine” of human-caused climate change in the Arctic. However, over the recent decade the rate of decline has slowed to a near-zero change. This shift in the rate of sea-ice decline cannot be fully explained by the steady increase of greenhouse gas emissions over the same period. Here we show that this slow-down may be due to internal variability of sea surface temperatures in the Eastern tropical Pacific that generate atmospheric circulation change reaching the Arctic. This change in the Arctic atmosphere has resulted in abnormal, abrupt warming from the early 2000s to 2012 and relative cooling in the recent years in the Arctic that can partially enhance and mask the effects of human-induced warming during the corresponding periods. Given the importance of this internal process in driving the Arctic climate on low–frequency time scales, a better understanding of its underlying mechanisms will improve future projections of Arctic climate.. Bio: Qinghua Ding received his Ph.D. from the University of Hawaii in 2008. His Ph.D. work was to understand the Asian monsoon variability over the last 60 years and its linkage with global circulation variability. In 2010 he started to work at University of Washington as Research Associate on developing an isotope-enabled global climate model and understanding the recent climate change in the Arctic and Antarctic from the perspective of climate dynamics. He found that the recent warming trends in the Arctic and Antarctic are partly attributed to a tropical SST-related natural variability. He joined the Polar Science Center in 2014 and accepted a faculty position at UCSB in 2016. For future research, his focus is on exploring polar-lower latitude connections in the past 1000 years by using atmosphere-ocean-ice fully coupled GCMs, isotope-enabled GCMs and paleo-climate proxy data. The ultimate goal is to provide more reliable projections of the polar climate response to anthropogenic climate forcing. — The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.

ThinkSpatial: Kate McDonald

On Tuesday, May 15, 2018 The UCSB brown-bag forum on spatial thinking presents The Accidental Digital Humanist: The Bodies and Structures Project and the Challenge of Spatial Humanities Kate McDonald Department of History University of California, Santa Barbara 12:00 p.m. Tuesday, May 15, 2018 | 3512 Phelps Hall (map) Flyer Abstract: Kate McDonald is excited to share a digital spatial history project, Bodies and Structures: Deep-Mapping the Spaces of Japanese History, which she is currently developing with her colleague David Ambaras (History, NC State). Bodies and Structures is a platform for researching and teaching the spatial histories of Japan, its empire, and the larger worlds of which they were a part. It begins from the premise that space and place are fundamental to humanistic inquiry. It unfolds into a method of writing spatial histories that reveal the multiple topologies of historical experience rather than a chronology of spatial thought or territorial transformation. The talk will introduce the site and the intellectual stakes of the project. In particular, she will focus on two themes: (a) how she started with a plan to write a new kind of spatial history and ended up knee-deep in the digital humanities; and (b) why, after two years into the project, she argues that the spatial humanities need a digital platform like Bodies and Structures. There will be time to explore and discuss the site — please bring your laptop in addition to your lunch! Bio: Kate McDonald is Assistant Professor of Modern Japanese History at the University of California, Santa Barbara. She is the author of Placing Empire: Travel and the Social Imagination in Imperial Japan (University of California Press, 2017) and co-director of the Bodies and Structures: Deep-Mapping the Spaces of Japanese History project. — The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.

On Tuesday, March 6, 2018 The UCSB brown-bag forum on spatial thinking presents Assimilating Spatial Data into a Global Ocean Model Timothy Devries Department of Geography University of California, Santa Barbara 12:00 p.m. Tuesday, March 6, 2018 | 3512 Phelps Hall (map) Flyer Abstract: The circulation of the ocean plays a major role in controlling Earth’s climate, but most global ocean circulation models have significant errors and biases, making their predictions suspect. This talk presents a way to correct these biases by assimilating large spatial datasets of oceanographic observations into a global ocean circulation model. I will discuss what observations can be used to correct model biases, how these are assimilated into the model, and give some examples of how the data-assimilated model can be applied to simulate ocean processes. Bio: Timothy received his PhD at UC Irvine in Earth System Science in 2010, and completed his postdoctoral training at UCLA. Since 2014, he has been an Assistant Professor in the Geography Department at UCSB. His research interests include the ocean’s role in the global carbon cycle, the cycling of nutrients and trace metals in the ocean, and ocean heat uptake. His research tools include numerical models, data assimilation, probabilistic models, and machine learning. — The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.

ThinkSpatial: Pyry Kettunen

On Tuesday, February 20, 2018 The UCSB brown-bag forum on spatial thinking presents How to Strengthen Technological Support for Wayfinding and Spatial Communication with Context-Dependent Landmarks and Geo-Pictures Pyry Kettunen Senior Research Scientist Department of GeoInformatics and Cartography Finnish Geospatial Research Institute 12:00 p.m. Tuesday, February 20, 2018 | 3512 Phelps Hall (map) Flyer Abstract: Wayfinding is the core intellectual component of everyday human navigation, which we often find challenging and in which we often make mistakes largely due to inaccurate spatial communication—particularly in unfamiliar environments. Wayfinding typically depends heavily on landmarks, that is, prominent features of the physical environment utilized as points of reference in geospatial thinking. In real use, utilized landmark sets can vary importantly between conditions and the individuals navigating, thus making interpersonal exchange about navigation arduous and even misleading. Still, such exchange plays a central role for the success of collaborative wayfinding efforts in everyday situations, such as a spontaneous gathering in a city, or even in lifesaving group tasks, such as search for a missing person. In this ThinkSpatial talk, I will present a short general history of spatial cognition research with regards to wayfinding, as well as present results from our empirical in situ landmark studies in nature that show the dependence of utilized landmark sets on summer/winter, and day/night conditions. I will discuss the acquisition of landmark, route, and configuration types of spatial knowledge from geospatial pictures that commonly serve as our initial exposures and wayfinding aids in unfamiliar environments. I will conclude with my suggestions for future work to enhance personal navigation technology with context‐dependent landmark‐based wayfinding guidance in collaborative settings, and my project at the spatial@ucsb. Bio: Pyry Kettunen is visiting the Center for Spatial Studies as a Fulbright Junior Scholar Feb-Jul 2018 for a research project on collaborative geospatial thinking. He is a Senior Research Scientist in the Department of Geoinformatics and Cartography at the Finnish Geospatial Research Institute (FGI) that is part of the National Land Survey of Finland (NLS‐FI). He received his M.Sc. (Tech.) in Geoinformatics from Helsinki University of Technology in 2008 and D.Sc. (Tech.) in Geoinformatics from Aalto University School of Engineering in 2014. His studies included an exchange year at the EPFL, Lausanne, Switzerland, and four months as a visiting grant researcher at the LMC lab of the Université Paris Descartes. Kettunen’s research has concentrated on human spatial cognition of landmarks and wayfinding as well as on development and usability of varied kinds of cartographic applications. His current research interests include interpersonal spatial cognition, cartographic animation, and web maps. His personal interests are in endurance sports in nature, choir or group singing when possible, and arts in general. — The objectives of the ThinkSpatial...

ThinkSpatial: Edzer Pebesma

On Tuesday, February 6, 2018 The UCSB brown-bag forum on spatial thinking presents How can Units of Measurement Improve Spatial Data Science? Edzer Pebesma Department of Geography University of California, Santa Barbara 12:00 p.m. Tuesday, February 6, 2018 | 3512 Phelps Hall (map) Flyer Abstract: Units of measurement are a well‐understood system for describing part of the reference of quantities. They help, for instance, in figuring out whether we can meaningfully compare or add two quantities, or what the unit of measurement of a product of quantities is. In this talk I will explore whether they can help spatial analysis: Can we automatically decide, based on the unit of measurement, whether a value associated with polygon or grid cell is spatially extensive, or intensive? Should the “unitless” unit be extended to handle incompatibility between weight ratios (g/g), counts of persons, and counts of wildfires? I will illustrate this with recent implementation work in the R packages udunits, units, and sf; see also https://doi.org/10.1016/j.csi.2017.10.002 Bio: Edzer Pebesma is professor in Geoinformatics at the University of Muenster, Germany. He is associate editor of Spatial Statistics and one of the editors in chief of the Journal of Statistical Software. He is an active developer of R spatial packages, and one of the authors of Applied Spatial Data Analysis with R, 2nd edition. — The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.
