Interactive Effects Of Climate Change-Induced Range Shifts And Wind Energy Development On Future Economic Conditions Of The Atlantic Surfclam Fishery, Stephanie Stromp, Andrew M. Scheld, John M. Klinck, Daphne M. Munroe, Eric N. Powell, Roger Mann, Sarah Borsetti, Eileen E. Hofmann

CCPO Publications

Rising water temperatures along the northeastern U.S. continental shelf have resulted in an offshore range shift of the Atlantic surfclam Spisula solidissima to waters still occupied by ocean quahogs Arctica islandica. Fishers presently are prohibited from landing both Atlantic surfclams and ocean quahogs in the same catch, thus limiting fishing to locations where the target species can be sorted on deck. Wind energy development on and around the fishing grounds will further restrict the fishery. A spatially explicit model of the Atlantic surfclam fishery (Spatially Explicit Fishery Economics Simulator) has the ability to simulate the consequences of fishery displacement …

Comments On "Reconsidering The Relationship Between Gulf Stream Transport And Dynamic Sea Level At U.S. East Coast" By Chi Et Al., Tal Ezer

CCPO Publications

Numerous recent studies found significant correlations between weakening of the Gulf Stream (GS) and rising coastal sea level (CSL) along the U.S. East Coast. Based on monthly altimeter data and Florida Current transport, Chi et al. (2023; here, CH23) argued that geostrophic adjustment of the GS is unlikely to drive variations in CSL in the Mid-Atlantic Bight (MAB). It is argued here that this conclusion cannot be universally applicable to all cases, since the monthly data disregard correlations previously found for short time scales based on hourly and daily data; the impact of GS variability on time scales of decades …

Corals At The Edge Of Environmental Limits: A New Conceptual Framework To Re-Define Marginal And Extreme Coral Communities, Verena Schoepf, Justin H. Baumann, Daniel J. Barshis, Nicola K. Browne, Emma F. Camp, Steeve Comeau, Christopher E. Cornwall, Héctor M. Guzmán, Bernhard Riegl, Riccardo Rodolfo-Metalpa, Brigitte Sommer

Biological Sciences Faculty Publications

The worldwide decline of coral reefs has renewed interest in coral communities at the edge of environmental limits because they have the potential to serve as resilience hotspots and climate change refugia, and can provide insights into how coral reefs might function in future ocean conditions. These coral communities are often referred to as marginal or extreme but few definitions exist and usage of these terms has therefore been inconsistent. This creates significant challenges for categorising these often poorly studied communities and synthesising data across locations. Furthermore, this impedes our understanding of how coral communities can persist at the edge …

Preparing Students To Solve Challenges Related To A Changing Climate, Mujde Erten-Unal, Dalya Ismael, Carol L. Considine

Civil & Environmental Engineering Faculty Publications

The National Academy of Engineering has identified restoring and improving urban infrastructure as one of the grand challenges for engineering. Urban coastal communities are particularly at risk as their infrastructure is experiencing frequent inundation related to climate change impacts. Rising sea levels in coastal communities create backflow into stormwater systems and deplete capacity. In addition, the increase in rainfall intensity, duration, and frequency related to climate change create additional challenges for aging infrastructure systems. To prepare students to solve these challenges, the Civil and Environmental Engineering (CEE) and Civil Engineering Technology (CET) programs at Old Dominion University (ODU) are introducing …

Marine Heatwaves Modulate The Genotypic And Physiological Responses Of Reef-Building Corals To Subsequent Heat Stress, Kristen T. Brown, Amatzia Genin, Matheus A. Mello-Athayde, Ellie Bergstrom, Adriana Campili, Aaron Chai, Sophie G. Dove, Maureen Ho, Devin Rowell, Eugenia M. Sampayo, Veronica Z. Radice

Biological Sciences Faculty Publications

Back-to-back marine heatwaves in 2016 and 2017 resulted in severe coral bleaching and mortality across the Great Barrier Reef (GBR). Encouragingly, some corals that survived these events exhibit increased bleaching resistance and may represent thermally tolerant populations that can better cope with ocean warming. Using the GBR as a natural laboratory, we investigated whether a history of minimal (Heron Island) or severe (Lizard Island) coral bleaching in 2016 and 2017 equates to stress tolerance in a successive heatwave (2020). We examined the genetic diversity, physiological performance, and trophic plasticity of juvenile (<10 cm) and adult (>25 cm) corals of two common genera ( …

Levels Of Autotrophy And Heterotrophy In Mesophotic Corals Near The End Photic Zone, Amy Carmignani, Veronica Z. Radice, Kathryn M. Mcmahon, Alex I. Holman, Karen Miller, Kliti Grice, Zoe Richards

Biological Sciences Faculty Publications

Mesophotic corals live at ~30-150 m depth and can sustain metabolic processes under light-limited conditions by enhancing autotrophy through specialized photoadaptations or increasing heterotrophic nutrient acquisition. These acclimatory processes are often species-specific, however mesophotic ecosystems are largely unexplored and acclimation limits for most species are unknown. This study examined mesophotic coral ecosystems using a remotely operated vehicle (Ashmore Reef, Western Australia at 40–75m depth) to investigate the trophic ecology of five species of scleractinian coral (from genera Leptoseris, Pachyseris, and Craterastrea) using stable isotope analyses (δ¹³C and δ¹⁵N) of host and symbiont tissues …

Coastal Squeeze, Climigration, And Equity Implications, Wie Yusuf

School of Public Service Faculty Publications

Summary: Coastal squeeze is impacting communities across the United States. Agricultural lands are affected by groundwater salt intrusion, habitats are lost due to limited space for species to migrate inland, natural capital and flood protection values are impacted by reduction in undeveloped land for natural ecosystems, infrastructure such as transportation are affected by flooding, and insurance companies are withdrawing from covering properties in coastal communities experiencing sea level rise and flooding. Resulting ‘climigration’ is occurring, for example, in Puerto Rico residents moving off the island, and subdivisions in North Carolina and Virginia being turned over to conservation. Lower-income communities are …

Research-Practice Collaborations To Address Equity Through Implementable, On-The-Ground Coastal Resilience Projects, Wie Yusuf

School of Public Service Faculty Publications

Summary. The discussion of research-practice collaborations to address equity through implementable, on-the-ground projects and programs converged around several interconnected themes that included: (1) prioritizing equity focus in defining and measuring projects’ success, (2) involving local communities in projects early on and through long-term monitoring, using interdisciplinary teams, and (3) incentivizing such projects through proper resourcing. Prioritizing equity in project measurement is only possible with the community’s involvement, and proper resourcing would ensure that community partners are resourced appropriately to support their resilience efforts.

Equity Concerns Underpinning Policy Analysis And Decision Making For Coastal Resilience, Wie Yusuf

School of Public Service Faculty Publications

Summary: Equity is increasingly becoming a consideration in resilience-focused policy. There is heightened interest in measuring how resilience policies, projects, and programs may impact equity. Equity may be advanced by a more inclusive policy process, well-developed communication channels, regular reference to the resilience research body of knowledge, and consultation with subject matter experts. There is need for increased clarity in the conceptual and operational definitions of equity, and consideration of the impact of resilience investments on a range of social and economic disparities.

Emergency Management For Equitable Coastal Resilience, Wie Yusuf

School of Public Service Faculty Publications

Summary: The discipline and practice of emergency management provide opportunities to promote equity in resilience. This may be accomplished by (1) expanding and deepening emergency management’s responsibilities to more explicitly incorporate mid-to-long-term recovery, and (2) advancing workforce diversity. Further, the prioritization of planning investments may promote more equitable recovery pathways for communities. Tracking of resilience investments and associated benefits across communities may provide opportunities to assess the equity of investments. Advancing resilience literacy and risk assessment among the citizenry may promote equity in resilience.

A Demonstration Of A Simple Methodology Of Flood Prediction For A Coastal City Under Threat Of Sea Level Rise: The Case Of Norfolk, Va, Usa, Tal Ezer

CCPO Publications

Many coastal cities around the world are at risk of increased flooding due to sea level rise (SLR), so here a simple flood prediction method is demonstrated for one city at risk, Norfolk, VA, on the U.S. East Coast. The probability of future flooding is estimated by extending observed hourly water level for 1927–2021 into hourly estimates until 2100. Unlike most other flood prediction methods, the approach here does not use any predetermined probability distribution function of extreme events, and instead a random sampling of past data represents tides and storm surges. The probability of flooding for 3 different flood …

The History Of Air Quality In Utah: A Narrative Review, Logan E. Mitchell, Christopher Zajchowski

Human Movement Studies & Special Education Faculty Publications

Utah has a rich history related to air pollution; however, it is not widely known or documented. This is despite air quality being a top issue of public concern for the state’s urban residents and acute episodes that feature some of the world’s worst short-term particulate matter exposure. As we discuss in this narrative review, the relationship between air pollution and the state’s residents has changed over time, as fuel sources shifted from wood to coal to petroleum and natural gas. Air pollution rose in prominence as a public issue in the 1880s as Utah’s urban areas grew. Since then, …

Empirically Derived Thermal Thresholds Of Four Coral Species Along The Red Sea Using A Portable And Standardized Experimental Approach, Nicolas R. Evensen, Christian R. Voolstra, Maoz Fine, Gabriela Perna, Carol Buitrago-López, Anny Cárdenas, Guilhem Banc-Prandi, Katherine Rowe, Daniel J. Barshis

Biological Sciences Faculty Publications

Global warming is causing an unprecedented loss of species and habitats worldwide. This is particularly apparent for tropical coral reefs, with an increasing number of reefs experiencing mass bleaching and mortality on an annual basis. As such, there is a growing need for a standardized experimental approach to rapidly assess the thermal limits of corals and predict the survival of coral species across reefs and regions. Using a portable experimental system, the Coral Bleaching Automated Stress System (CBASS), we conducted standardized 18 h acute thermal stress assays to quantitively determine the upper thermal limits of four coral species across the …

The UN COP26 2021 conference on climate change offers the chance for world leaders to take action and make urgent and meaningful commitments to reducing emissions and limit global temperatures to 1.5 °C above pre-industrial levels by 2050. Whilst the political aspects and subsequent ramifications of these fundamental and critical decisions cannot be underestimated, there exists a technical perspective where digital and IS technology has a role to play in the monitoring of potential solutions, but also an integral element of climate change solutions. We explore these aspects in this editorial article, offering a comprehensive opinion based insight to a …

Coastal Upwelling Enhances Abundance Of A Symbiotic Diazotroph (Ucyn-A) And Its Haptophyte Host In The Arctic Ocean, Corday R. Selden, Sveinn V. Einarsson, Kate E. Lowry, Katherine E. Crider, Robert S. Pickart, Peigen Lin, Carin J. Ashjian, P. Dreux Chappell

OES Faculty Publications

The apparently obligate symbiosis between the diazotroph Candidatus Atelocyanobacterium thalassa (UCYN-A) and its haptophyte host, Braarudosphaera bigelowii, has recently been found to fix dinitrogen (N²) in polar waters at rates (per cell) comparable to those observed in the tropical/subtropical oligotrophic ocean basins. This study presents the novel observation that this symbiosis increased in abundance during a wind-driven upwelling event along the Alaskan Beaufort shelfbreak. As upwelling relaxed, the relative abundance of B. bigelowii among eukaryotic phytoplankton increased most significantly in waters over the upper slope. As the host’s nitrogen demands are believed to be supplied primarily by UCYN-A, …

Emerging Technologies And Approaches For In Situ, Autonomous Observing In The Arctic, Craig M. Lee, Michael Degrandpre, John Guthrie, Victoria Hill, Ron Kwok, James Morison, Christopher J. Cox, Hanumant Singh, Timothy P. Stanton, Jeremy Wilkinson

OES Faculty Publications

Understanding and predicting Arctic change and its impacts on global climate requires broad, sustained observations of the atmosphere-ice-ocean system, yet technological and logistical challenges severely restrict the temporal and spatial scope of observing efforts. Satellite remote sensing provides unprecedented, pan-Arctic measurements of the surface, but complementary in situ observations are required to complete the picture. Over the past few decades, a diverse range of autonomous platforms have been developed to make broad, sustained observations of the ice-free ocean, often with near-real-time data delivery. Though these technologies are well suited to the difficult environmental conditions and remote logistics that complicate Arctic …
