Abstract: The composition of particles found in the upper tropospheric / lower stratospheric (UTLS) has now been studied in situ and in real time for a quarter century. First deployed in 1998, NOAA's Particle Analysis by Laser Mass Spectrometry (PALMS) instrument showed the complex internal and external mixing state of aerosols in this region of the atmosphere. Developed jointly by NOAA and Purdue, the PALMS-Next Generation (-NG) instrument has expanded on these measurements. Using data from these instruments, our group was able to show unexpected complexity in the LS aerosol. Biomass burning particles, sourced from the troposphere and likely entrained in convection, were found up to 4 km above the local tropopause. Meteoric smoke particles, sedimented from the mesosphere and internally mixed with sulfuric acid, were often found to also contain materials from spacecraft ablation. These two particle types were also often found to be internally mixed, indicative of coagulation processes in the LS. This presentation will first describe these observations and then discuss how this unexpected complexity impacts our climate, precipitation and atmospheric chemistry.

Abstract: Modeling has predicted that reductions in ocean pH and increases in temperature will reduce vital rates (survival and growth) of North Pacific crab stocks and hence the target levels of fishing mortality consistent with sustainable harvesting. However, these predictions have been based on the best estimates of the effects of changes in ocean pH and temperature on vital rates from laboratory experiments. The effects are quantified of several climate and market sources of variability for Alaskan red king on predicted optimal fishing mortality rates, including changes in ocean chemistry and temperature on vital rates, non-linear relationships between prices, costs and catch, and the uncertainty in population dynamics models. The declines in survival consistently lead to predictions of a reduction in productivity and hence optimal level of fishing intensity over time, but the extent of change is uncertain. Uncertainty related to the effects of ocean pH and temperature on vital rates and variability among Earth System Models and future emission scenarios are the dominant sources of uncertainty, although potential fluctuations in prices and costs are also consequential. Simulations are used to explore the relationship between changes in ocean pH or temperature and vital rates and hence identify approaches to reduce the uncertainty in estimates of future projections of target fishing mortality rates.

Title: New insights into deep sea biodiversity distributions from integrated environmental omics, multi-vehicle operations, and autonomous sampling approaches

NOAA Library Seminar Series

Presenter(s): Annette Govindarajan, Biology Department, Woods Hole Oceanographic Institution

Sponsor(s): NOAA Omics and NOAA Library

Seminar Contact(s): Nicole Miller (nicole.miller@noaa.gov)

Remote Access: https://vimeo.com/event/5772989

Abstract: This presentation will highlight expeditions pioneering an integrated exploration approach combining eDNA analyses, autonomous sampling, and robotic platforms on the E/V Nautilus near Hawaii, and in the American Samoan archipelago. Using water collected by a Deep Autonomous Profiler, we conducted surface to seafloor eDNA surveys. We used autonomous samplers mounted on the AUV Mesobot to conduct sampling transects in the mesopelagic. The Mesobot surveys included sampling of the deep sound scattering layers using verified directed sampling, a novel multi-vehicle adaptive sampling technique that includes communication between the uncrewed surface vehicle DriX and Mesobot to direct sampling based on acoustic backscatter. To asses seamount biodiversity, we conducted bottom sampling surveys with the ROV Hercules and are comparing eDNA data with ROV video. Our surface-to-seafloor results demonstrate the power of our integrated technology approach in revealing deep sea biodiversity patterns.

Abstract: Outreach and education significantly influence the trajectory of a student's career, often triggering the initial spark of inspiration. With that in mind, this study aims to examine the National Weather Service (NWS) outreach and education portfolio for the K-12student population. Through a content analysis of Weather Forecast Office (WFO) websites, review of NWS engage database, and qualitative interviews with NWS personnel (e.g. Warning Coordinating Meteorologists, Lead forecasters, forecasters, and hydrologists), trends and gaps will be identified to develop best practices from an educational perspective to foster more engaging and fruitful outreach. Addressing the current operations of outreach and educational resources are critical to NOAA's mission of protecting life and property, empowering student awareness and resilience in the face of weather threats in addition to increasing the NOAA workforce.

Abstract: The Supercell Database storm track collection was created by research scientists within the National Severe Storms Laboratory in order to document the structure and evolution of right-moving supercells across the United States. The analysis of 309 supercell thunderstorms containing 521 mesocyclones indicates that most storms produce a single dominant mesocyclone, which is consistent with the classic supercell lifecycle. However, a significant portion of storms produced multiple mesocyclone cycles particularly in the Great Plains. AzShear exceedance analysis at both the mid-and low-levels indicates a positive correlation between storm longevity and frequent radar signatures, with the mid-levels displaying more frequent stronger rotation signatures. Notably, the 98th percentile remains a shared rarity amongst both levels. A regional comparison between the Great Plains and the Southeast indicates that Plains storms are typically longer-lived, more isolated, and exhibit more extended mesocyclone cycling. Southeastern storms are typically shorter-lived, more clustered, and often disrupted by mesoscale boundaries and storm interactions. These results highlight the value of AzShear exceedance tactics for evaluating mesocyclone intensity and longevity, providing a synopsis of research on mesocyclone evolution and severe supercell development.

Abstract: Coastal cities across the world have been increasingly exposed to severe storms which threaten and strain their populations, infrastructure, and economies. Despite nearly 40% of the global population residing in these cities, the processes that drive coastal urban rainfall modifications are poorly understood. Houston, the fourth most populated metropolitan area in the United States, frequently experiences intense convective thunderstorms, which makes it an ideal region to study coastal urban-precipitation modification. The primary goal of this research is to understand the dynamics of the built environment -particularly its urban heat island (UHI) and building mechanical effects- in altering these coastal and cloud processes. An isolated thunderstorm sea breeze case from the summer2022 NSF-funded Convective-clouds Urban Boundary-layer Experiment (CUBE) and DOE Tracking of Aerosol Convective Interaction Experiment (TRACER) field campaigns was simulated to investigate anthropogenic influences. The work focuses on the novel model framework of an urbanized Weather Research and Forecasting (uWRF) model linked to the MYNN Eddy Diffusivity Mass-Flux (EDMF) scheme.

NOAA Science Seminar Series

Title: Pelagic Sargassum in the Atlantic Ocean: what happened in the past 20 years?

Presenter(s): Chuanmin Hu, University of South Florida

Sponsor(s): NOAA Ocean Color Coordinating Group (NOCCG)

Remote Access: https://meet.google.com/hnd-zams-bgo

Seminar Contact(s): Cara.Wilson@NOAA.gov

Abstract: Pelagic Sargassum, one type of brown macroalgae or seaweed, has been known to be abundant in the Sargasso Sea since its first report in the 15^th century by Christopher Columbus. In 2011, however, large amounts of Sargassum started to appear in the Caribbean Sea, causing adverse impacts on the coastal environments and turning an otherwise critical open-ocean habitat into a coastal hazard. Since then, the research community has spent enormous effort in finding better ways to assess its spatial distributions and temporal changes as well as improved understandings of the reasons behind these changes. Here, using satellite observations and other data, we first review the remote sensing techniques used to map and quantify pelagic Sargassum, and then report a possible regime shift in Sargassum distributions in the Atlantic Ocean, characterized by the emergent Great Atlantic Sargassum Belt and dramatic decline in Sargassum abundance in the north Sargasso Sea. We also discuss the possible reasons behind such a regime shift and pathway forward in future Sargassum research.

Title: Understanding shark depredation in Florida for-hire recreational fisheriesNOAA Library Seminars

Presenter(s): Hannah Aycock, Ph.D. Candidate, University of Miami

Sponsor(s): NOAA Library and NOAA Education

Seminar Contact(s): library.seminars@noaa.gov

Remote Access: https://vimeo.com/event/5771444

Accessibility: Captions are available during the live presentation and once uploaded to the NOAA Library YouTube Channel automatic captions are added. Sign language interpreting services and closed captioning are available, but need to be requested at least 5 days before the event.

Abstract: Reports of shark depredation"when a shark bites a hooked fish"have increased in Florida recreational fisheries over the past decade. This emerging challenge carries significant conservation and fisheries management implications, yet currently lacks formal policy or mitigation strategies. My research integrates species distribution modeling, stakeholder engagement, and targeted fieldwork to identify the ecological and human drivers of depredation and inform practical, evidence-based mitigation strategies.

Recordings: Recordings will be shared 24 hours after the event on the NOAA Library YouTube channel.

Title: Creatures of Darkness: Investigating Life and Light in the Twilight ZoneNOAA Library Seminars

Presenter(s): Heather Bracken-Grissom, Florida international University, Professor and Assistant Director of Coastlines and Oceans, Institute of Environment

Abstract: Bioluminescence is rare on land but common currency in deep-sea ecosystems. Our work on deep-sea shrimp has revealed that bioluminescence is much more common than previously reported. The integration of -omics with morphology has revealed that light organs (photophores) come in a variety of forms and underlying genetic machinery. Over the past 10 years, my lab has traced the evolution of bioluminescent organs in the deep sea, demonstrated an expanded function of photophores beyond counterillumination and significantly increased the number of bioluminescent species. Recent work investigates the evolution of bioluminescence across the shrimp tree of life with the inclusion ~1000 taxa and a phylogenomic framework, while others explore the drivers of light on visual ecology and evolution. This talk attempts to summarize how the often unrecognized but awe-inspiring world of glowing shrimp has advanced our understanding of bioluminescence in the deep sea.

Recordings: Recordings will be shared 24 hours after the event on the NOAA Library YouTube channel.
