This document describes a Research Experience for Teachers (RET) program run by the Center for Latin American & Caribbean Studies at the University of Wisconsin-Milwaukee. The program sends K-12 teachers from Milwaukee Public Schools to Panama for 3-4 weeks over the summer to study tropical ecology and participate in scientific research. The goal is to bring this experience back to the classroom to develop curriculum on tropical ecology. Teachers collaborate with scientists and have access to resources to create classroom materials like activities, photos, videos and blogs. The program aims to support educators teaching underrepresented student populations and expand STEM programming.
The document discusses using OPeNDAP as a means to provide access to gridded remote sensing data from various sources. It describes setting up an OPeNDAP server to serve various data formats and implementing a system using a PostGIS database to add spatial and temporal metadata to help discover and access the data more easily. Key lessons learned include that while OPeNDAP performs well, significant infrastructure is needed to handle the variety of data formats and projections, and it is tempting to add too many features to the system.

Aquatic connectivity - Prof. Brian Fry ACEAS Grandaceas13tern
The document summarizes a workshop on aquatic connectivity that was held in January 2013 at the Moreton Bay Marine Research Station. Seventeen experts in fields related to connectivity such as genetics, modeling, and field studies attended to discuss the importance of connectivity in maintaining populations and the tools available to study connectivity. Heavy weather disrupted ferry access to the island during the workshop but it proceeded as planned. The workshop participants aimed to develop synthetic approaches to studying landscape connectivity across different techniques and ecosystems and produce a manuscript summarizing their discussions.
The eReefs project aims to create an integrated operational system spanning paddock to ocean that combines critical data sources, forecasting and modeling tools, and visualization reporting to improve reef management. The system will support monitoring current and past reef conditions, integrate social and economic data, and serve as a demonstration for a comprehensive coastal information system. It will include high resolution regional models, global forecasting products, and relocatable local models. The overarching goal is to transform reef management through improved access and use of environmental information.
This document discusses several projects at CSIRO Computational Informatics (CCI) related to time series data extraction, visualization and exploration from sensor networks and gridded models. It summarizes the TasMAN project which developed a web-based system for exploring and visualizing sparse marine sensor and climate model data. It also discusses the Sense-T and SensorCloud infrastructure for ingesting, annotating, and providing APIs for accessing point-based time series data from multiple research projects. The document compares the SensorCloud API and OGC SOS standards for exchanging versus visualizing time series data.
The document summarizes the Australian Geoscience Data Cube (AG-DC), which was developed to efficiently analyze large volumes of remote sensing data. The AG-DC arranges spatial data temporally and spatially using a "dice and stack" method, subdividing data into regular tiles with timestamps that are then stacked as dense temporal stacks. This allows flexible yet efficient analysis of huge remote sensing archives like Landsat at continental scales. The AG-DC has been used to perform analyses over entire remote sensing archives that previously took days in just a few hours.
Prof. Michael Raupach "Synthesis in science and society" ACEAS Grand 2014 part Baceas13tern

Dr MIchael Vardon, ABS, ACEAS 2014 "Synthesis in environmental accounting"aceas13tern
Environmental-economic accounting aims to integrate environmental data with economic metrics to provide a comprehensive assessment of the interrelated natural and economic systems. It draws on concepts from various disciplines to establish relationships between environmental stocks and flows and represent them physically and monetarily in standardized accounts. Countries have developed systems like the UN's System of Environmental-Economic Accounting to produce regular reports integrating these domains and identify information gaps. While complex, accounting benefits decision-making by making environmental and economic trade-offs more transparent.
Prof. Tony McMichael ACEAS 2014 "Synthesis in public health" aceas13tern
Charles Darwin drew on the ideas of geologist Charles Lyell and demographer Thomas Malthus to help shape and underpin his Theory of Evolution. One Health recognizes the connection between human, animal, and environmental health. While scientists since the 1800s noted similarities between human and animal diseases, human and animal medicine remained separate until the 20th century. Recent recognition of the One Health concept has led to its application in public health and animal health. Much public discussion and policy response to rising obesity has been misdirected by focusing on individuals, genes, healthcare or other single factors rather than viewing it as a population-level issue within an historical, ecological, and technological context drawing on social sciences.

This document discusses methods for indirectly measuring leaf area index (LAI) at the EucFACE research site using measurements of photosynthetically active photon flux density (PPFD) above and below the forest canopy. On cloudy days when diffuse light dominates, canopy transmittance measurements can be inverted to estimate total LAI. Comparing different indirect LAI measurement methods shows agreement. Analysis of long-term MODIS data across southeast Australia indicates that water availability, not elevated CO2, is the main driver of LAI dynamics at large spatial scales. Future work aims to test ecosystem models of LAI response to rainfall and CO2 using phenocam imagery for continuous monitoring of vegetation green-up.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
