Enlisting Students To Transcribe Historical Climate And Weather Data For Research: Building Knowledge Translation Via Classroom-Based Citizen Science, Drew F. Bush, Victoria Slonosky, Geoffrey Pearce, Renee Sieber

Journal of Community Engagement and Scholarship

DRAW (Data Rescue: Archives & Weather) is a citizen science project that asks the Canadian public to take part in transcribing millions of meteorological observations recorded between 1871 and 1963 at McGill University’s Observatory in Montreal, Quebec, which was demolished in 1963. We examine how classroom-based curricula can integrate citizen science so youth can learn more about their community via engagement with the local history of weather conditions and impacts. Conducted in March 2018, this research examined knowledge translation during a three-week course module through written reflections, classroom video footage, exit interviews, and a final group research assignment. We worked ...

Stony Brook Radar Observatory Radar Data For February 20, 2019, Mariko Oue

SoMAS Research Data

Stony Brook Radar Observatory (SBRO) has been in operation since March in 2017 (-73.127E, 40.897N, https://you.stonybrook.edu/radar/). The flagship radar of SBRO is a very sensitive, sophisticated, and well-calibrated Ka-band (35-GHz) scanning fully-polarimetric radar (KASPR). The radar measurements are complemented by two profiling radar systems operating at W-band (94-GHz, ROGER) and K-band (24-GHz, MRRPro). KASPR, ROGER, and MRRPro at SBRO collected triple frequency data during a snow event on February 20, 2019. Analyses of dual wavelength ratio, mean vertical Doppler velocity, and polarimetric radar variables from the triple frequency measurements can be used to identify ...

Seasonal Controls On Nearshore Hypoxia In A Small Coastal Embayment, Stephen Alexander Huie

Physics

Dissolved oxygen (DO) is an important biogeochemical factor that strongly influences nearshore coastal ecosystems. Low DO (hypoxic) events can cause physiological stressful environments for ecological and economically important species, potentially leading to mass mortalities. In order to better assess drivers of coastal hypoxia, we collected data from monthly cruises on the inner shelf and nearshore moorings inside and outside a small coastal embayment (San Luis Obispo Bay on the Central California Coast) across the full upwelling season (March to August). During the late spring and early summer, we found that the nearshore near-bottom temperature-DO (T-DO) relationship aligned with the shelf ...

Stony Brook Radar Observatory Radar And Lidar Data For February 25, 2020, Mariko Oue, Katia Lamer

SoMAS Research Data

Observations collected during the 25-February-2020 deployment of the Vapor In-Cloud Profiling Radar at the Stony Brook Radar Observatory clearly demonstrate the potential of G-band radars for cloud and precipitation research. The field experiment, which coordinated an X-, Ka, W-and G-band radar, revealed that the differential reflectivity from Ka-G-band pair provides larger signals than the traditional Ka-W pairing underpinning an increased sensitivity to smaller amounts of liquid and ice water mass and sizes. The data include:

1) Vapor In-Cloud Profiling Radar (VIPR) collected on 24-26 February 2020

2) W-band profiling radar (ROGER) collected on 25 February 2020

3) Ka-band Scanning Polarimetric ...

Reginald Sutcliffe And The Invention Of Modern Weather Systems Science, Jonathan E. Martin

Purdue University Press Book Previews

Despite being perhaps the foremost British meteorologist of the twentieth century, Reginald Sutcliffe has been understudied and underappreciated. His impact continues to this day every time you check the weather forecast. Reginald Sutcliffe and the Invention of Modern Weather Systems Science not only details Sutcliffe’s life and ideas, but it also illuminates the impact of social movements and the larger forces that propelled him on his consequential trajectory. Less than a century ago, a forecast of the weather tomorrow was considered a practical impossibility. This book makes the case that three important advances guided the development of modern dynamic ...

Comprehensive Record Of Volcanic Eruptions In The Holocene (11,000 Years) From The Wais Divide, Antarctica Ice Core, Jihong Cole-Dai, David G. Harris, Joshua A. Kennedy, Michael Sigl, Joseph R. Mcconnell, T. J. Fudge, Lei Geng, Olivia J. Maselli, Kendrick C. Taylor, Joseph M. Souney

Ice Core and Environmental Chemistry Lab Datasets and Publications

A comprehensive record (WHV2020) of explosive volcanic eruptions in the last 11,000 years is reconstructed from the West Antarctica Ice Sheet Divide deep ice core (WDC). The chronological list of 426 large volcanic eruptions in the Southern Hemisphere and the low latitudes during the Holocene are of the highest quality of all volcanic records from ice cores, owing to the high-resolution chemical measurement of the ice core and the exceptionally accurate WDC timescale. No apparent trend is found in the frequency (number of eruptions per millennium) of volcanic eruptions, and the number of eruptions in the most recent millennium ...

Ecological Risk Assessment Of Managed Relocation As A Climate Change Adaptation Strategy, Aviv Karasov-Olson, Mark W. Schwartz, Julian D. Olden, Sarah Skikne, Jessica J.

Executive Summary

Changing climate and introduced species are placing an increasing number of species at risk of extinction. Increasing extinction risk is increasing calls to protect species by relocating, or translocating, them to locations with more favorable biotic or climatic conditions. Managed relocation, or assisted migration, of species entails risks to both the conservation target organisms being moved as well as the recipient ecosystems into which they are moved.

Recognizing this risk, calls have been made for practitioners interested in considering a managed relocation project to engage in a serious risk assessment prior to advancing a project. We engaged a ...

State Of Satiation Partially Regulates The Dynamics Of Vertical Migration, Ryan P. Bos, Tracey Sutton, Tamara Frank

Marine & Environmental Sciences Faculty Articles

Vertical migrations into shallower waters at night are beneficial for migrators as they reduce predation risk and allow migrators to encounter a higher density of prey. Nevertheless, ocean acoustics data and trawl data have shown that a portion of some vertically migrating populations remain at depth and do not migrate. One hypothesis for this phenomenon is the Hunger-Satiation hypothesis, which in part states that the non-migrating portion of the migrating species-assemblage refrains from migrating if they have full or partially full stomachs from daytime or nocturnal feeding. However, stomach fullness of the non-migrating subpopulation compared to the migrating portion has ...

Comparison Of A Smartfin With An Infrared Sea Surface Temperature Radiometer In The Atlantic Ocean, Robert J. W. Brewin, Werenfrid Wimmer, Phillip J. Bresnahan, Tyler Cyronak, Andreas J. Andersson, Giorgio Dall’Olmo

Marine & Environmental Sciences Faculty Articles

The accuracy and precision of satellite sea surface temperature (SST) products in nearshore coastal waters are not well known, owing to a lack of in-situ data available for validation. It has been suggested that recreational watersports enthusiasts, who immerse themselves in nearshore coastal waters, be used as a platform to improve sampling and fill this gap. One tool that has been used worldwide by surfers is the Smartfin, which contains a temperature sensor integrated into a surfboard fin. If tools such as the Smartfin are to be considered for satellite validation work, they must be carefully evaluated against state-of-the-art techniques ...

Diurnal Cycle Of Passive Microwave Brightness Temperatures Over Land At A Global Scale, Zahra Sharifnezhad, Hamid Norouzi, Satya Prakash, Reginald Blake, Reze Khanbilvard

Publications and Research

Satellite-borne passive microwave radiometers provide brightness temperature (TB) measurements in a large spectral range which includes a number of frequency channels and generally two polarizations: horizontal and vertical. These TBs are widely used to retrieve several atmospheric and surface variables and parameters such as precipitation, soil moisture, water vapor, air temperature profile, and land surface emissivity. Since TBs are measured at different microwave frequencies with various instruments and at various incidence angles, spatial resolutions, and radiometric characteristics, a mere direct integration of them from different microwave sensors would not necessarily provide consistency. However, when appropriately harmonized, they can provide a ...

From Hector Mine M7.1 To Ridgecrest M7.1 Earthquake. A Look From A 20-Year Perspective, Sergey Pulinets, Marina Tsidilina, Dimitar Ouzounov, Dmitry Davidenko

Mathematics, Physics, and Computer Science Faculty Articles and Research

The paper provides a comparative analysis of precursory phenomena in the ionosphere and atmosphere for two strong earthquakes of the same magnitude M7.1 that happened in the same region (North-East from Los Angeles) within a time span of 20 years, the Hector Mine and Ridgecrest earthquakes. Regardless of the similarity of their location (South-Eastern California, near 160 km one from another), there was one essential difference: the Hector Mine earthquake happened during geomagnetically disturbed conditions (essential in the sense of ionospheric precursors identification). In contrast, the quiet geomagnetic conditions characterized the period around the time of the Ridgecrest earthquake ...

A Reimagining Of The Chacoan World, Larry Benson, Richard W. Loose

USGS Staff -- Published Research

A new paradigm of the Chacoan world is presented, wherein Chaco Canyon is considered to be a mostly unoccupied architectural complex that functioned primarily as a pilgrimage destination. Chaco was the political, religious, and social focal point of people living in outlying regions. The resident population of the Canyon consisted of a small number of caretakers, charged with maintaining great house structures, food supplies, and their ceremonial contents. Chacoan chiefdoms were mostly located in large, well-watered, agriculturally-based communities situated at the base of mountains that ring the San Juan Basin, e.g., the Chuskas. Chiefly elites lived year-round in those ...

Studies Of The Tilts Of Atmospheric Scatterers By Windprofiler Radars, Farnoush Attarzadeh

Electronic Thesis and Dissertation Repository

MST (Mesosphere–Stratosphere–Troposphere) radars are powerful instruments for observing the differences in refractive indexes in the air. By tracking refractive index perturbations, these radars can determine wind speeds and turbulence strengths in the atmosphere from the ground up to 15 km altitude. In this project, we used 6 Doppler Radars to study the correlation between horizontal and vertical winds in the Troposphere to find scatterer tilts. However, instrumental effects due to small tilts in the radar beam can also cause such correlations, thus our studies cover that as well. Scatterers are best known for being the result of turbulence ...

Agricultural Innovation And Adaptation To Climate Change: Insights From Genetically Engineered Maize, Seungki Lee, Yongjie Ji, Giancarlo Moschini

CARD Working Papers

Climate change is one of the major threats to the global food supply, and adaptation by technological progress is believed to be essential. What is the scope of the required innovation tasks? To address this question, we estimate the yield gain in US maize production due to a major novel technology: genetically engineered (GE) varieties. Next, the yield model is used to extrapolate future expected yields given climate change projections from twenty large-scale models and two warming scenarios. We find that climate change entails significant yield shortfalls. The scale of these yield gaps, by the end of the century, ranges ...

A Multiscale Framework For Disentangling The Roles Of Evenness, Density, And Aggregation On Diversity Gradients, Daniel J. Mcglinn, Thore Engel, Shane A. Blowes, Nicholas J. Gotelli, Tiffany M. Knight, Brian J. Mcgill, Nathan J. Sanders, Jonathan M. Chase

College of Arts and Sciences Faculty Publications

Ecology published by Wiley Periodicals LLC on behalf of Ecological Society of America Disentangling the drivers of diversity gradients can be challenging. The Measurement of Biodiversity (MoB) framework decomposes scale-dependent changes in species diversity into three components of community structure: species abundance distribution (SAD), total community abundance, and within-species spatial aggregation. Here we extend MoB from categorical treatment comparisons to quantify variation along continuous geographic or environmental gradients. Our approach requires sites along a gradient, each consisting of georeferenced plots of abundance-based species composition data. We demonstrate our method using a case study of ants sampled along an elevational gradient ...

Atlantic Sailfish (Istiophorus Albicans) Distribution Off The East Coast Of Florida From 2003 To 2018 In Response To Sea Surface Temperature, Meredith M. Pratt

Mako: NSU Undergraduate Student Journal

The Atlantic sailfish (Istiophorus albicans) ranges from 40°N to 40°S in the Western Atlantic Ocean and has great economic and recreational value for sport fishers. Off the east coast of Florida, recreational fishing boats often target this species due to its size, speed and strength. This project aimed to determine the relationship between sea surface temperature (SST) and the distribution of Atlantic sailfish caught and released over a fifteen-year period (2003 to 2018). Tagging information was collected from The Billfish Foundation and NOAA who have the most extensive programs for billfish. Using the time and location of each ...

The discovery of multi-species synchronous spawning of scleractinian corals on the Great Barrier Reef in the 1980s stimulated an extraordinary effort to document spawning times in other parts of the globe. Unfortunately, most of these data remain unpublished which limits our understanding of regional and global reproductive patterns. The Coral Spawning Database (CSD) collates much of these disparate data into a single place. The CSD includes 6178 observations (3085 of which were unpublished) of the time or day of spawning for over 300 scleractinian species in 61 genera from 101 sites in the Indo-Pacific. The goal of the CSD is ...
