Keynote Address: Climate Change: From Global To New York Scale, Christopher D. Thorncroft

CHAR

This talk is concerned with the science and impacts of climate change from global to New York scales. It will provide an assessment of how the climate has changed over the past Century based on a purely observational perspective. The scientific basis for anthroprogenic climate change will be explained and discussed including a description of the “greenhouse effect” and why it is important for life on this planet. We will briefly discuss global and local consequences of a warmer climate and what we need to be prepared for going forward in the coming decades.

The Geochemistry Of Loess: Asian And North American Deposits Compared, Daniel R. Muhs

United States Geological Survey: Staff Publications

Loess is widely distributed over Asia and North America and constitutes one of the most important surficial deposits that serve as terrestrial records of the Quaternary. The oldest Pleistocene loess in China is likely ∼2.6 Ma, thus spanning much or all of the Pleistocene. In North America, most loess is no older than the penultimate glacial period, with the exception of Alaska, where the record may go back to ∼3.0 Ma. On both continents, loess deposits date primarily to glacial periods, and interglacial or interstadial periods are represented by paleosols. Both glacial and non-glacial sources of silts that comprise the …

Solar Eclipse Induced Atmospheric Turbulence Effects On High Altitude Balloons, Fnu Anamika, Denise Buckner, Peter Henson, Jennifer Fowler, Nanette Valentour

2017 Academic High Altitude Conference

The North Dakota Atmospheric Education Student Initiated Research (ND-AESIR) team launched a balloon during the total solar eclipse in Rexburg, Idaho. After the umbra’s passage, the balloon experienced unexpectedly high levels of atmospheric turbulence. Video footage taken from the payload displays the conditions, and analysis of flight path data models created from the iridium GPS confirm that unusually violent turbulence occurred. These forces caused the key rings holding the bottom of the parachute to the payload train to rip open; the balloon and parachute flew away and the payloads free fell to the surface from an altitude of 68,301 feet. …

Physoon - Radiation Detection In Various High Altitude Environments, Christopher Helmerich

2017 Academic High Altitude Conference

Physoon is a high altitude ballooning payload designed and built by members of the Space Hardware Club for the purpose of comparing cosmic and terrestrial radiation from a variety of environmental conditions, including clear days, night times, solar events (eclipses, solar flares, coronal mass ejections), and thunderstorms. Over three design iterations, Physoon has flown eleven times with various combinations of Geiger counters sensors: a low energy Alpha-Beta-Gamma detector, an unshielded high-energy Beta-Gamma detector, and a shielded high-energy Beta-Gamma detector. One of these iterations successfully recovered data from high altitude during totality of the Great American Solar Eclipse. Another iteration was …

Use And Implementation Of The Automatic Packet Reporting System (Aprs) On High Altitude Payloads., Sam Fink, Robert Moody, Carson Keeter, Cassandra Runyon, Cyndi Hall

2017 Academic High Altitude Conference

Once a weather balloon enters the uncontrollable realm of nature upon release it is subject to a high degree of freedom and flight path options. Passive tracking methods become essential to physically follow the trajectory, the balloon, and its payload. The Automatic Packet Reporting System (APRS) provides an ideal platform for tracking high-altitude and low earth orbit instrumentation because at zenith there is no radio horizon. Demonstrated aboard the International Space Station, this simple system provides the maximum tracking range at very low power and cost with very high accuracy, by utilizing existing federally funded infrastructure. An amateur radio license …

Eclipse Ballooning Stem Outreach For Elementary, Middle, And High School Education, Peter Henson, Fnu Anamika, Denise Buckner, Marissa Saad, Caitlin Nolby

2017 Academic High Altitude Conference

To promote Science, Technology, Engineering and Mathematics (STEM) education through ballooning, the North Dakota Space Grant Consortium (NDSGC) organizes an annual Near-Space Balloon Competition (NSBC) for students in grades 6 - 12. Students across the state of North Dakota have the opportunity to launch experiments into a near- space environment. The students learn how to write proposals, design payloads, and analyze data. They learn through an active, inquiry-based style that will prepare them for real-world engineering and critical thinking jobs. In 2016, NSBC proposed Great American Eclipse as the theme for the competition, thus the students were focused on designing …

Impactful Practice: Lessons Learned Through Ballooning Outreach, Tracy Knowles, Leandro Braga, Alex Eberle, Tom Busby, John Paul Beard, Jessica Glasscock, Jacolby Gardner, Matt Smither

2017 Academic High Altitude Conference

The goal of Bluegrass Community and Technical College’s (BCTC) Eclipse Outreach Ambassador Project was to get students across the Bluegrass excited and educated about the 2017 total solar eclipse. Several years ago the BalloonSat Project was started to provide hands-on earth and atmospheric science experiences to BCTC students. In linking the two initiatives, we allowed BCTC BalloonSat team members to continue learning to design, build, test, fly and retrieve balloon-borne payloads while using a novel method by which to engage local elementary and middle school students in learning more about and anticipating the upcoming eclipse. Eclipse practice flights carried payloads …

Placing A High-Altitude Balloon In The Path Of Totality, Nicholas Jordan, Christopher Helmerich

2017 Academic High Altitude Conference

The UAH Space Hardware Club had conducted 70 flights prior to the Eclipse. In this time, we have gained valuable skills and experience which we have put into practice and passed on through the years. We put these skills into practice for the Eclipse. Our first challenge was finding where to launch. We started out by looking for suitable locations inside totality. We also examined a map of totality at 80,000 ft. We then ran predictions based on past weather during that time of year. By compiling multiple past predictions, we eliminated possible launch sites. We had multiple payloads, some …

Ecosystem Drought Response Timescales From Thermal Emission Versus Shortwave Remote Sensing, Erika Andujar, Nir Krakauer, Chuixiang Yi, Felix Kogan

Publications and Research

Remote sensing is used for monitoring the impacts of meteorological drought on ecosystems, but few large-scale comparisons of the response timescale to drought of different vegetation remote sensing products are available. We correlated vegetation health products derived frompolar-orbiting radiometer observations with a meteorological drought indicator available at different aggregation timescales, the Standardized Precipitation Evapotranspiration Index (SPEI), to evaluate responses averaged globally and over latitude and biome.The remote sensing products are Vegetation Condition Index (VCI), which uses normalized difference vegetation index (NDVI) to identify plant stress, Temperature Condition Index (TCI), based on thermal emission as a measure of surface temperature, and …

Impact Of Climate Change On New York City’S Coastal Flood Hazard: Increasing Flood Heights From The Preindustrial To 2300 Ce, Andra J. Garner, Michael E. Mann, Kerry A. Emanuel, Robert E. Kopp, Ning Lin, Richard B. Alley, Benjamin P. Horton, Robert M. Deconto, Jeffrey P. Donnelly, David Pollard

School of Earth & Environment Departmental Research

We combine downscaled tropical cyclones, storm-surge models, and probabilistic sea-level rise projections to assess flood hazard associated with changing storm characteristics and sea-level rise in New York City from the preindustrial era to 2300. Compensation between increased storm intensity and offshore shifts in storm tracks causes minimal change in modeled storm-surge heights through 2300. However, projected sea-level rise leads to large increases in future overall flood heights associated with tropical cyclones in New York City. Consequently, flood height return periods that were ∼500 y during the preindustrial era have fallen to ∼25 y at present and are projected to fall …

Emerging Hotspot Analysis Of Florida Manatee (Trichechus Manatus Latirostris) Mortality (1974-2012), Crystal Ann Bass

HCNSO Student Theses and Dissertations

The Florida manatee (Trichechus manatus latirostris) is a protected species that is vulnerable to both anthropogenic and natural causes of mortality. The ability of wildlife managers to oversee regulation of this species is based on available abundance estimates and mortality data. Using existing manatee mortality data collected by Florida Fish and Wildlife Conservation Commission (FWC) from 1974-2012, this study focuses on identifying significant spatial clusters of high values or “hotspots” of manatee mortality and the temporal patterns of these hotspots using the novel “emerging hotspot analysis” ArcGIS tool. The categories of manatee mortality included in this analysis were …

Unmanned Aerial Systems For Monitoring Trace Tropospheric Gases, Travis J. Schuyler, Marcelo I. Guzman

Chemistry Faculty Publications

The emission of greenhouse gases (GHGs) has changed the composition of the atmosphere during the Anthropocene. Accurately documenting the sources and magnitude of GHGs emission is an important undertaking for discriminating the contributions of different processes to radiative forcing. Currently there is no mobile platform that is able to quantify trace gases at altitudes(UASs) can be deployed on-site in minutes and can support the payloads necessary to quantify trace gases. Therefore, current efforts combine the use of UASs available on the civilian market with inexpensively designed analytical systems for monitoring atmospheric trace gases. In this context, this perspective introduces the …

Stable Isotopes In The Eye Lenses Of Doryteuthis Plei: Exploring Natal Origins And Migratory Patterns In The Eastern Gulf Of Mexico, Brenna A. Meath

USF Tampa Graduate Theses and Dissertations

Stable isotope analysis is an emerging tool to examine trophic pathways and migratory patterns of marine organisms. Squid are widely distributed in coastal and deep water regions of the Gulf of Mexico. Stable isotope ratios of carbon and nitrogen found within cephalopod tissues can provide information on both trophic level and habitat of their food sources. More recently, ontogenetic changes in stable isotope ratios within squid eye lenses have been documented. Concentric layers of crystallin proteins are added to the lens as the squid ages; the center of the lens contains the oldest layer and the youngest layers are on …

Nepal has an extreme altitudinal range from 60–8850m with heterogeneous topography and distinct climatic zones. The country is considered a biodiversity hotspot, with nearly a quarter of the land area located in protected areas. Nepal and the surrounding Himalayan region are particularly vulnerable to climate change because of their abrupt ecological and climatic transitions. Tens of millions of people rely on the region’s ecosystem services, and observed and modeled warming trends predict increased climate extremes in the Himalayas. To study the ecological impacts of climate change in Nepal and inform adaptation planning, we review the literature on past, present, and …

How Accurate Are Satellite Estimates Of Precipitation Over The North Indian Ocean?, Satya Prakash, M. R. Ramesh Kumar, Simi Mathew, R. Venkatesan

Publications and Research

Following the launch of the Global Precipitation Measurement (GPM) Core Observatory in early 2014, motivated from the successful Tropical Rainfall Measurement Mission (TRMM) satellite, an advanced and sophisticated global multi-satellite precipitation product – Integrated Multi- satellitE Retrievals for GPM (IMERG) was released at finer spatio-temporal scales. This precipitation product has been upgraded recently after several refinements and supposed to be superior to other existing global or quasi-global multi-satellite precipitation estimates. In the present study, IMERG precipitation is comprehensively evaluated for the first time against moored buoy observations over the north Indian Ocean at hourly scale for the study period of …

Assessment Of Differences Between Near-Surface Air And Soil Temperatures For Reliable Detection Of High-Latitude Freeze And Thaw States, Farjana Shati, Satya Prakash, Hamid Norouzi, Reginald Blake

Publications and Research

Near-surface air temperature and the underlying soil temperature are among the key components of the Earth’s surface energy budget, and they are important variables for the comprehensive assessment of global climate change. Better understanding of the difference in magnitude between these two variables over high-latitude regions is also crucial for accurate detections of freeze and thaw (FT) states. However, these differences are not usually considered and included in current remote sensing-based FT detection algorithms. In this study, the difference between near-surface air temperature at the 2-meter height and soil temperature at the 5-centimeter depth is assessed using ground-based observations that …

Cruise Data For Neuston Net And Paired Bongo Net Tows From 47 Stations In The Northern Gulf Of Mexico From R/V Pelican Cruise Lf2017a July 2017, Jay R. Rooker, R.J. David Wells

DEEPEND Datasets

Shelf and slope waters in the Deep Water Horizon oil spill (DWHOS) area are known to serve as critical spawning, nursery, and foraging habitat of several important oceanic species including billfishes (e.g. blue marlin, white marlin, sailfish), tunas (bluefin tuna, yellowfin tuna), and other pelagic taxa (swordfish, dolphinfishes). The aim of this component was to further investigate potential ecological effects of the DWHOS on pelagic fishes during the early life period. Larval fishes were sampled from 48 stations in the northern Gulf of Mexico and cruise data was collected at each site including latitude/longitude, date, time and environmental data (sea …

Dietary Transfer Of Heavy Metals In Manatees, E. M. Smith, Dimitri Giarikos, A. Daniels, Amy Hirons

Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures

In recent decades, manatees and dugongs globally have exhibited potentially detrimental levels of a variety of heavy metals in their body tissues. The threatened Florida manatee (Trichechus manatus latirostris), which is a subspecies of the West Indian manatee (Trichechus manatus), has shown corresponding high levels of heavy metals in their blood, skin, liver, and kidneys. As obligate herbivores, these animals rely heavily upon seagrasses as a major component of their diet. Globally, seagrasses at low latitudes have high levels of heavy metals in their tissues. Detrimental levels of heavy metals in Sirenians have not been established …

A Critical Examination Of The Climate Change Vulnerability And Adaptation Literature In Nunavut, Canada, Sarah Prentice

Independent Study Project (ISP) Collection

This paper attempts to study the climate change vulnerability and adaptation literature in Nunavut, a province in the Canadian Arctic. The paper begins with a review of literature produced by Inuit organizations on colonization in the Canadian Arctic and Nunavut specifically, then systematically reviews the literature on climate change vulnerability and adaptation. Using a post-colonial analysis, this study found that while the climate change vulnerability and adaptation literature attempts to attend to colonial histories and legacies, it often falls short. Climate change vulnerability and adaptation literature had minimal representation of colonization, residential schooling, sanatoria, and Inuit Qaujimajatuqangit. This may perpetuate …

Shift In Icelandic Plant Populations Due To Climate Change: Through The Lens Of Natural Dyes, Molly Pluenneke

Independent Study Project (ISP) Collection

Northern residing plant species are at the highest risk for extinction due to temperature rise related to climate change (Schöb, Manuel, Choler & Veit, 2009). Climate change has also led to a northern shift in the geographic distribution of plant species (Parmesan & Yohe, 2003). This could lead to a necessary alteration in the way natural resources are utilized in arctic countries like Iceland (Lim-Camacho et al, 2017). The purpose of this study is to analyze the way in which Icelandic plant species used in natural dye practices may shift in distribution due to climate change and the potential impact …

Sites were measured using a 200m line transect and 40-plot method. Data was also collected from a sand beach habitat to compare to the diversity and distribution of mangrove habitats. Diversity was analyzed using Simpson’s Index of Diversity and an ANOVA test on the average number of species found per plot in each site. Density was analyzed using an …

The Role Of Young Environmental Activists In Iceland And Furthering Youth Engagement With Environmental Issues, Story Schwantes

Independent Study Project (ISP) Collection

This paper looks at the role of youth environmental activism in Iceland and how these actors view their work in a country which has long held a reputation as one of the greenest in the world. Much of the credit for that distinction goes not to careful choices, sacrifice, or excellent stewardship but rather to its ideal geography providing massive geothermal energy which Iceland turns into electricity, a clean renewable source. So are there young environmental activists in Iceland, and if so what do they do? Short answer: yes, and they study and talk. The long answer is more complex. …
