Cultural Legacies in the Amazonian Holocene: A Paleoecological Perspective S. Yoshi Maezumi, Max Planck Institute of Geoanthropology The extent to which Indigenous land use and cultural burning practices have altered modern ecosystems is a hotly debated topic in archaeology and paleoecology. To address this issue, an interdisciplinary approach combining archaeological, archaeobotany, palaeoecolgoy, and palaeoclimatology is used to investigate climate-human-ecosystem interactions in the Amazon. These data indicate Indigenous Amazonians employed diverse subsistence strategies that combined cultural burning, agroforestry, polyculture, and soil amelioration that maximized subsistence diversity without large-scale land clearing. These data provide evidence of resource diversification, improved food security, and sustainable anthropogenic landscapes during increased climate variability and expanding Indigenous populations during the late Holocene. These data provide an example of long-term anthropogenic landscapes that can inform management and conservation efforts for sustainable futures of tropical ecosystems in the 21st century. 3:45 PM - 5:00 PM |

Jennifer Graham, USGS and New York Water Science Center Cyanobacteria increasingly are a global water-quality concern because of the potential for these organisms to develop harmful blooms that affect ecologic, economic, and public health. Cyanobacterial harmful algal blooms (CyanoHABs) can lead to a decrease in water quality and affect many of the recreational and ecological benefits of parks that include lakes. The New York State Office of Parks, Recreation and Historic Preservation (OPRHP) is a state agency within the New York State Executive Department charged with the operation of state parks and historic sites. Many New York State parks include lakes or other freshwater bodies, which can be susceptible to CyanoHABs. The OPRHP faces difficult decisions regarding prevention of and response to CyanoHABs. Decision analysis is often used to inform complex decisions regarding natural resource management. Structured decision making (SDM) breaks down complex decisions into their basic parts and reconstructs the problem into a framework that allows for collaborative examination and development of suitable actions. The U.S. Geological Survey (USGS) partnered with OPRHP and the New York State Department of Environmental Conservation to develop a SDM template for managing CyanoHABs in OPRHP parks. Two parks, Moreau Lake State Park and Rockland Lake State Park, served as case studies to motivate and test the template. This presentation will describe how the principles of SDM can be used to navigate the challenging problems associated with managing CyanoHABs using the case studies as examples. Management objectives and strategies for CyanoHABs in OPRHP parks, strategies to evaluate consequences and manage trade-offs, and potential challenges to the implementation of preferred alternatives will be discussed. 3:45 PM - 5:00 PM |

Sea-level rise and thin layer placement: How they affect salt marsh C and N cycling Charles Schutte, Rowan University Around half of New Jersey’s salt marshes are not keeping pace with sea-level rise and face increasing inundation and salinity. How will this affect soil-based ecosystem services that these marshes provide, like nitrogen removal and carbon burial? In this presentation, Dr. Schutte will discuss how sea-level rise and other human-caused disturbances may interact to exacerbate marsh loss and share results about how one method to protect marshes from sea-level rise, thin later placement, affects soil nitrogen cycling process rates. 3:45 PM - 5:00 PM |

Wave Energy: Perspective on Applications, Technologies, and Challenges Muhammad Hajj, Stevens Institute of Technology In comparison to solar and wind energy, wave energy is more predictable, and incessant with a global potential of the order of tens of thousands of terawatt-hours per year. Yet, from a readiness perspective, there has not been a prevailing design for wave energy converters for many reasons. Developing the technology requires design of components including the prime mover, foundation or mooring, power take-off, and control systems. In this talk, advances made towards realizing electric power from wave energy will be discussed. A summary of an effort supported by the US Department of Energy and led by researchers at Stevens Institute of Technology and in collaboration with researchers from Virginia Tech and Resolute Marine to design of a 100 kW will be presented. 3:45 PM - 5:00 PM |

Analyzing Low-abundance Environmental Analytes using Mass Spectrometry Anyin Li, University of New Hampshire Electrospray ionization (ESI) is an indispensable mass spectrometry method for solution phase analytes including environmental contaminants. While MS detectors measure no more than picoamps of ion current, conventional ESI methods produce a minimum of nanoamps (nA) current, wasting a large portion of analytes, and causing non-uniform responses in the analysis. Recent research has developed methods to generate ESI in femtoamp (fA) currents and femto flow (fL/min) flow rates. When generating nanoscale initial charged droplets, the femto ionization regimes provide improved performances for hydrophilic analytes including glycans, glycopeptide, and intact proteins. This seminar also showcases how the low ion current regime may be utilized to ionize environmental contaminants in nonpolar extraction solvent. Lastly, femto ESI was utilized to generate individual ions for charge detection mass spectrometry, and for preparing single atom catalyst. 3:45 PM - 5:00 PM |

PFAS Screening and Protein Absolute Quantitation by Mass Spectrometry Hao Chen, New Jersey Institute of Technology In collaboration with Prof. Mengyan Li at NJIT, we recently developed a rapid analytical method for per and polyfluoroalkyl substances (PFASs) using nano-electrospray high-resolution mass spectrometry (Nano-ESI-HRMS), which was recently published in Water Research, 2022, 219, 118542. This method was applied to aqueous film-forming foams (AFFFs) and wastewater samples collected from three local wastewater treatment plants (WWTPs). The method exhibited high sensitivity with lower limits of detection (LODs) of 3.2~36.2 ng/L for 22 target PFAS analytes. In AFFF formulations, Nano-ESI-HRMS enabled the first-time detection of trifluoromethanesulfonic acid (TFMS), perfluoroethyl cyclohexanesulfonate (PFECHS), 6:2 fluorotelomer sulfonyl amido sulfonic acid (6:2 FTSAS-SO2), N ammoniopropyl perfluoroalkanesulfonamidopropylsulfonate (N-AmP-FASAPS, n=3–6), ketone perfluorooctanesulfonic acid (Keto-PFOS), fluorotelomer unsaturated amide sulfonic acid (FTUAmS, n = 7), and 6:2 fluorotelomer amide (6:2 FTAm). Their structures were verified by the tandem MS analysis using collision-induced dissociation. Overall, Nano-ESI-HRMS enabled comprehensive PFAS quantitative analysis and suspect screening, applicable for rapid investigation and assessment of PFAS related exposure and treatment in environmental matrixes. In this talk, I will also introduce our recent effort in combining electrochemistry (EC) with mass spectrometry (MS) for protein absolute quantitation without using expensive standards. We expect it will make a good impact in quantitative proteomics. 3:45 PM - 5:00 PM |

Sustainability challenges produced by melting ice sheets: insights from the sediment archive Sandra Passchier, Montclair State University Glacial ice is susceptible to atmospheric and ocean warming, and ice mass loss is a major concern due to its impact on sea level, hazards such as glacial outburst floods, and water resources, affecting millions of people. However, the fate of land ice in the light of prolonged warming is a topic of major uncertainty because of the complex feedbacks of land ice in the climate system. This talk will highlight how glacial sedimentologists use geological archives of different time resolutions, from years to millions of years, to understand an ice-sheet’s response to warming. Records of relatively recent annual glacial varves testify of the dynamic behavior of ice sheets at speeds that exceed their modeled retreat rates. Furthermore, sediment archives deposited millions of years ago provide a glimpse into a world with reduced ice cover in a different greenhouse climate state. The data can be translated to inform decision making towards sustainable development under different future emission scenarios. 3:45 PM - 5:00 PM |

Weitian Wang, Montclair State University Robotics technology has served humans in numerous application fields, especially product assembly in manufacturing contexts. Global competitors and technological advancements result in great challenges and much more complicated working environments for the manufacturing. Human-robot collaboration (HRC) has numerous vital and outstanding advantages to substantially lessen the amount of fixed production costs in comparison to variable costs. HRC provides a great solution to the complex hybrid manufacturing tasks. The cooperation of humans and robots in collaborative tasks can take advantage of the differing strengths from both sides. In this talk, I will give a broad introduction of robotics research and education at Montclair State University. Then I will share some of my research projects focusing on human-robot collaboration in smart manufacturing contexts including robot learning from human demonstrations, human factors in human-robot collaboration, and collaboration quality estimation. Experimental results and discussions in real-world human-robot collaborative contexts will be presented. This talk is supported in part by the National Science Foundation under Grant CNS-2104742 and Grant CMMI-2138351. 3:45 PM - 5:00 PM |

Forests as Social Safety Nets During the Covid-19 Lockdowns: Evidence from India Alder Keleman Saxena, Northern Arizona State University This presentation reports on research assessing the social-ecological dynamics of the Covid-19 lockdowns in India in 2020 and 2021. Preliminary findings of research in forest- adjacent communities in three states (Assam, Madhya Pradesh, and Himachal Pradesh) suggest that while forest resources did serve as a buffer for some of the most vulnerable households, they did not stand in as a full substitute for the market-derived goods and income opportunities curtailed by the lockdowns. Findings from the research to-date suggest two major conclusions: first, the ecological context (including the seasonal timing) of the lockdowns influenced the extent to which forest communities did (or did not) have access to supporting forest resources; and second, communities identified failings in formal public-sector safety nets – rather than lack of access to forests - as a major source of distress during the lockdown periods. 3:45 PM - 5:00 PM |

Na'Taki Osborne Jelks, Spelman College Environmental justice communities, those disproportionately affected by pollutants, are simultaneously exposed to multiple environmental stressors and also experience social and cultural factors that may heighten their health risks in comparison to other communities. Availability of fine-grained, community-level data is limited to support said communities’ appeals for public health practice, planning, and policy changes. In Northwest Atlanta, Georgia’s Proctor Creek Watershed community residents (watershed researchers), academics, and non-profit organizations have leveraged local, community knowledge; community science methods; and participatory approaches to identify, document, and analyze the impacts of local environmental hazards and quality of life stressors. This highly collaborative and interdisciplinary work has helped to improve municipal services and community-municipality collaboration while also demonstrating that the democratization of science can help fill critical data gaps about local conditions and pollution sources, advance environmental justice, and impact changes in the implementation of urban policies and practice that influence community health. 3:45 PM - 5:00 PM |
