Tandem-L is a proposed mission to monitor dynamic earth processes using radar. It would provide high-resolution measurements of forests, biomass, earthquakes, volcanoes, sea ice, permafrost, soil moisture, glaciers, and ocean currents. Tandem-L aims to improve on current missions by offering 3-10 meter resolution with weekly coverage. Its digital beamforming radar system could measure deformation, ice flow, water levels, and generate digital terrain models. The mission would advance understanding of processes like deforestation, forest biomass change, biodiversity, landslides, and help monitor essential climate variables.

Dynamic Earth Monitoring and Climate Change

Tandem-L: A proposal for a radar mission for
environmental and climate change research

Tropical wetlands like peat swamp forests and mangroves provide valuable ecosystem services but are under threat from climate change and land conversion. They store vast amounts of carbon in their soils, with estimates of up to 2000-3000 Mg of carbon per hectare stored belowground. However, their carbon stocks are not well quantified and they require specialized methods and guidelines for monitoring, reporting, and verification under REDD+ programs due to their unique belowground carbon dynamics. Effective conservation of tropical wetlands through REDD+ could significantly reduce greenhouse gas emissions while protecting important habitats and coastal communities.

WE1.L09.5 - ESTIMATION OF FOREST BIOMASS CHANGE FROM FUSION OF RADAR AND LIDA...

grssieee

1. The document discusses the use of radar and lidar measurements from the proposed DESDynI mission to estimate various aspects of forest biomass and dynamics, including biomass change over time, disturbance from events like storms and fires, degradation from logging, and forest recovery. 2. Key requirements for the DESDynI mission include mapping biomass levels globally with errors less than 20% and mapping disturbance and regrowth at 100m resolution annually. 3. Case studies with lidar and radar data show the missions potential for directly measuring forest height changes and growth, as well as detecting small amounts of biomass loss and degradation from SAR imagery.

Oral presentation at National Conference on Beach Preservation Technology (2012)

awhays

This study examined how beach nourishment designs impact marine turtle nesting in Brevard County, Florida. The researchers found that (1) beach slope and width, as well as sand moisture content and grain size, are important nesting cues for loggerhead turtles, (2) full-scale beach restorations had a larger negative effect on nesting success rates than smaller dune restorations, and (3) altering the beach slope through nourishment can affect its ability to function as an effective nesting cue, leading to more false crawls. This research lays the groundwork for understanding how different nourishment designs impact turtle nesting behavior.

Martial BERNOUX "Managing soil carbon through agro-ecological practices"

Global Risk Forum GRFDavos

This document summarizes a presentation on managing soil carbon through agro-ecological practices. The presentation argues that soil carbon management can address both global problems like climate change through mitigation of greenhouse gases as well as local problems like soil degradation. It shows that many sustainable land management practices that sequester carbon can also increase agricultural yields, even in drylands. However, estimates of carbon sequestration potential need to be validated at finer geographical scales. The presentation promotes moving from carbon markets based on estimated sequestration to ones based on adoption of proven practices. It emphasizes agro-ecological practices as a win-win strategy.

Aerial Recon in Bakken, ND

Applied Ecological Services

Remote sensing using aerial imagery can help inventory natural resources and detect changes in the Bakken region of North Dakota. High resolution imagery can be used to map land cover, identify sensitive habitats and species, and detect impacts from oil and gas development over time. Infrared sensors can detect vegetation stress and leaks along pipelines. Case studies showed aerial imagery successfully located water leaks and located unauthorized brine dumps by observing vegetation die-off and soil discoloration. Periodic imaging can monitor impacts and aid in environmental compliance.

Stumpf et al, 2003

Fernando Jefferson Prudencio Paredes

This document describes two algorithms for determining water depth from high-resolution satellite imagery: a standard linear transform algorithm and a new ratio transform algorithm. The linear transform requires tuning five parameters and does not work for very low albedo bottoms, while the ratio transform requires tuning only two parameters and can handle low albedo features. Both algorithms were tested on IKONOS imagery of two coral reef atolls in the Hawaiian Islands against lidar bathymetry data. The ratio transform performed as well as the linear transform and was more robust, stable between areas, and able to retrieve depths over 25m. However, it was also slightly noisier and had trouble resolving fine structures below 15-20m depth.

The document discusses deforestation in the Amazon and its impacts. It notes that expansion of agriculture has increased deforestation rates and could eliminate 40% of Amazon forests by 2050. Models show that large-scale deforestation reduces evapotranspiration and increases surface air temperatures and changes rainfall patterns. However, the impacts of small-scale, complex mosaics of land cover are less clear. Deforestation has increased river discharge in some watersheds due to reduced evapotranspiration and increased runoff, but has not significantly changed precipitation totals or the timing of the rainy season. The impacts on extreme weather events are still being studied using advanced modeling techniques.

Dynamic Habitat - CLLAMM technical briefing

University of Adelaide

This document summarizes research on dynamic habitat mapping in the Coorong region of Australia. It includes sections on developing a digital elevation model, sediment mapping, habitat mapping, mudflat geomorphology, and spatial modeling of mudflat availability and fish habitat. Methods such as bathymetric modeling from imagery, sediment modeling using generalized additive modeling, and developing a dynamic habitat model linking bathymetry, water levels from hydrodynamic modeling, and outputs like mudflat area are described. Key findings are that the South Lagoon contains most of the available mudflat habitat and manipulating water levels between 0-0.5m AHD would maximize habitat productivity and availability.

Goswami2010 - NDSWI Spectral Index

Santonu Goswami

This study investigated the impact of variation in soil moisture on Arctic ecosystems by manipulating water tables in a thaw lake basin. Spectral reflectance was used to monitor surface hydrology at different scales. Results showed that near infrared reflectance was most affected by presence of surface water, while blue reflectance was not. A normalized difference surface water index (NDSWI) using blue and near infrared bands strongly correlated with and predicted measured water table depth throughout the growing season. Spatial patterns of elevation, water table depth, and the predictive ability of NDSWI were analyzed across the study area at different scales.

Alarming loss of soil carbon stores in the Boreal forest zone in Finland

TERN Australia

This document discusses upscaling flux tower data using remote sensing and modeling to produce global carbon and water flux maps. It summarizes work merging OzFlux tower data, AusCover remote sensing, eMAST modeling, and data integration to upscale measurements from plant to global scales. Two examples are provided of data-model integration at Tumbarumba and along the North Australian Tropical Transect, showing improved ecosystem process understanding through spatially resolved inputs to models from remote sensing. The work finds primary drivers of variability are land use and LAI rather than photosynthetic capacity, and scaling up through TERN facilitates integrated temporal and spatial information.

Assessing the Success of Tropical Peatlands Restoration: A Review

GlobalEnvironmentCentre

This document summarizes a presentation on enhancing sustainability of forestry practices on peatlands in Indonesia. It discusses that tropical peatlands cover around 11% of global peatland area, with over half located in Southeast Asia, especially Indonesia. The document outlines the important ecosystem services provided by peatlands, including carbon storage, and notes that degradation from activities like drainage and fires have significantly impacted peatlands and increased carbon emissions. It emphasizes the need for restoration efforts to rewet degraded peatlands and reestablish vegetation to help reduce degradation and fire risk over time.

This document summarizes the methodology used in a study analyzing the effects of land use change on sediment accumulation in lakes in West Central Alberta, Canada. Sediment cores from 13 lakes were analyzed to develop sedimentation profiles and determine accumulation rates. Watershed characteristics were inventoried using GIS. Statistical analyses examined correlations between landscape/land use factors and sedimentation rates to assess impacts of disturbances like forestry, oil/gas development, and roads. Comparisons identified the most disturbed watersheds and how sediment yields changed over time.

BEES is an end-to-end mission performance simulator for the BIOMASS satellite designed to evaluate expected performance of the mission. It consists of modules for scene generation, system simulation, ionospheric effects, processing, and performance evaluation. BEES simulates the full processing chain from raw data to level 1 and 2 products in a realistic way while including major error sources. Validation of BEES is challenging due to its complexity and random components, requiring statistical comparison to theoretical expectations using large homogeneous scenes and Monte Carlo simulations.

This document presents a new approach for classifying multispectral remote sensing images using weighted pixel statistics. The approach combines spectral signatures from images to perform accurate classification. Simulation results on synthesized test images show the approach provides more accurate classifications with fewer unclassified zones compared to traditional weighted order statistics methods, demonstrating the efficiency of the proposed approach. Future work is outlined to further evaluate performance.

This document summarizes the results of the first bistatic SAR experiment using JAXA's PALSAR satellite radar and NEC's Pi-SAR-L airborne radar. The bistatic image showed higher signal-to-noise ratio, lower azimuth resolution, and ability to detect different targets than the monostatic images. Analysis found the bistatic image had better visibility of small features due to its shorter receiver-target distance. Its lower resolution was likely due to Pi-SAR-L not having synchronization functions. Some targets appeared differently between images from their varying incidence angles and signal levels.

It provides an overview of the software used to generate DSMs from PRISM triplet images and details on archiving over 5,000 processed scene DSMs. It then describes the process used to create 1° x 1° tile mosaics, including correcting for biases between relative and absolute DSMs. Examples of mosaics created for Japan and Bhutan are shown and their contributions to studies on glacial lake outburst floods in Bhutan are discussed. The goal is to complete a global 10m resolution DSM mosaic.

Ecological Risk Assessment

Mohamed Herzallah

Combined effects of global climate change and toxicants are complex and can be exacerbated or compensated for at higher levels of biological organization. The study discusses 4 ecological mechanisms using 3 case studies: 1) Demographic processes can compensate or propagate individual impacts to population levels. 2) Climate change can reduce resistance and recovery from toxicants at population and community levels. 3) Acquired tolerance to stressors often comes at a cost of reduced genetic diversity and increased susceptibility. 4) Species vulnerability is influenced by traits and landscape changes from climate change altering toxicant exposures. Long-term experiments incorporating realistic climate projections are needed to make reliable predictions.

This study evaluated the use of multispectral and hyperspectral sensor data to estimate crop residue cover over agricultural areas. Hyperspectral data provided more accurate residue cover estimates than multispectral data due to greater spectral sensitivity. Models using a cellulose absorption index performed best. Residue cover estimates from hyperspectral data were substituted into models developed using multispectral data, improving accuracy of estimates from broader coverage sensors. Future work will focus on sensor fusion methods and integrating residue cover information into hydrologic models.

This document summarizes research on sediment transport and geomorphology in the Nisqually Delta to inform restoration and climate adaptation planning. Key findings include: 1) Field measurements found river sediment loads are high in fines that deposit in marshes, with potential accretion rates of less than 2 mm/yr. 2) Modeling shows sediment redistributes through tidal channels and is exported from marshes, with climate change potentially increasing sediment delivery. 3) Adaptive management options include trapping sediment upstream and creating new distributaries to build marsh resilience to sea level rise.

This document summarizes a study of landscape changes on a peat dome in coastal Riau, Sumatra from 1995-2010. Key findings include: 1) Illegal logging from 2000-2009 resulted in extensive drainage through ditches that lowered water tables and caused significant peat subsidence and loss of forest biomass. 2) From 2003-2010, terrain models show mean subsidence of 0.17 meters over the study area, indicating a loss of around 20 tons of CO2 per hectare per year from oxidized peat soils. 3) Forest biomass monitoring plots from 2004-2011 show a continuing decline in biomass years after logging, with the largest trees most affected by

GEOG8280.02, The role of the oceans

Scott St. George

The oceans play several key roles in the climate system. They absorb and reflect solar radiation, transport heat around the globe through currents, and are the source of most atmospheric water vapor. The oceans' high heat capacity means they can store vast amounts of heat, making them the primary regulator of Earth's climate. Water has a much higher specific heat than land or air, allowing the oceans to absorb and gradually release heat. Their deep mixing and global conveyor circulation distribute heat energy worldwide. As a result, the oceans have a moderating influence on global and regional climates.

This document discusses Earth's structure and processes. It describes Earth's principal systems like the atmosphere, hydrosphere, biosphere, lithosphere, and others. It explains that Earth is made of layers, including the crust, mantle, and core. The crust consists of tectonic plates that are constantly moving via processes like convection in the mantle, resulting in earthquakes, volcanoes, and mountains over time. Plate tectonics and weathering/erosion shape the surface and cause environmental changes.

Tropical Peatland Rehabilitation

Wetlands International

The document discusses the challenges and potential benefits of rehabilitating degraded tropical peat swamp forests. It notes that tropical peatlands provide important hydrological, biodiversity, livelihood and carbon storage functions. However, extensive areas in Southeast Asia have become degraded through logging, drainage, fire and agricultural/plantation use. This degradation has led to problems like increased flooding and fire risk. Rehabilitation faces significant ecological constraints like loss of seed sources and impaired hydrology. Social constraints include lack of support and conflicting land uses. Successful restoration may require addressing both short-term social and long-term ecological needs. Key questions for restoration include defining goals, understanding constraints, and identifying barriers and opportunities.

Coastal carbon_Andy Steven

TERN Australia

This document summarizes information about coastal carbon in Australia. It discusses how Australia's coasts are biodiverse, highly productive, store significant carbon, and are undergoing change. Coastal ecosystems like seagrasses, salt marshes, and mangroves store large amounts of carbon in their soils. However, degradation of these habitats releases their stored carbon. The document outlines how organizations like CSIRO and TERN are studying carbon storage and fluxes in coastal regions. This includes quantifying carbon sequestration potential and modeling changes under different scenarios. Monitoring at a study site in southeast Queensland examines how land use impacts carbon sources and cycling in a peri-urban estuary system.

1) The structure of microbial communities is influenced by both historical legacies like glacial till composition and contemporary environmental conditions. 2) Microbial function is primarily driven by soil characteristics rather than community structure, indicating some functional redundancy. 3) A study in the Antarctic Dry Valleys found that both glacial till and wet/dry site classifications significantly contributed to differences in microbial community structure, but only soil properties influenced functional enzyme activity levels.

Rockglaciers genesis and growth in a degrading mountaincryosphere (Southern F...

University of the Highlands and Islands

This study analyzed glacial and periglacial landforms in the Southern French Alps to reconstruct the landscape evolution since the last glacial maximum and better understand rockglacier development patterns. Cosmogenic dating and weathering rind measurements identified three post-LGM glacial stages and three generations of rockglaciers. Most rockglaciers likely developed in the second half of the Holocene, and their distribution depended on both climate and geomorphic conditions following glacier retreat. The results provide new constraints on late glacial retreat in the region, suggesting valley glaciers persisted lower than previously thought until the early Holocene.

The document describes flow banding in the Dun Caan Basalt on Raasay, Scotland. It finds that the basalt contains a lower flat domain with sub-horizontal planar banding and an upper contorted domain where the banding is complexly folded. The banding is thought to have formed from intense non-coaxial shear during emplacement of an unusually high-temperature and low-viscosity lava, similarly to a lava-like ignimbrite. Upon cooling and slowing, the upper part underwent slumping which deformed the earlier planar banding into a contorted fabric.

The document analyzes and compares the physical and chemical properties of soils under three different vegetation types - swamp forest, secondary forest, and savanna - within the forest zone of Badagry, Nigeria. Significant differences were found between the soils, including higher sand and silt levels in the savanna and secondary forest soils compared to the swamp forest soils. The soils overall are sandy, slightly acidic, and low in nutrients. Maintaining crop yields will require judicious use of fertilizers due to the soils' poor chemical properties.

This document summarizes a study on how microclimate affects the natural regeneration of forests in dryland areas of Portugal after agricultural abandonment. The study found that the rate of regeneration of holm oak trees depends on local microclimate conditions, with regeneration being faster in areas with higher potential solar radiation and slower in areas with lower potential solar radiation. The researchers developed a predictive model for holm oak regeneration based on microclimate variables that can help improve reforestation planning efforts. Validating the model over time showed it has potential for predicting natural regeneration patterns under different climate scenarios.

This document provides an overview of geophysics techniques for mineral exploration. It discusses how geophysical measurements relate to the physical properties of rock bodies and how these properties produce geophysical responses that can be measured on the surface. Key points covered include: - Different energy sources and geophysical techniques measure different physical properties like density, magnetism, and elastic properties. - Physical properties depend on lithology, alteration, and mineralization of the subsurface target body. - Geophysical measurements made on the surface are related to the physical property, geometry, and depth of the buried target body. - Examples of airborne and ground geophysical surveys in British Columbia demonstrate how different techniques provide complementary information at various scales.

The supersites provide baseline carbon measures, link field data to carbon dynamics at different scales, connect high resolution data to remote sensing, and inform ecosystem modeling. Specific sites discussed include the Great Western Woodlands, FNQ Rainforest, and Warra Tall Eucalypt supersites. Research at these sites measures vegetation, biomass, carbon stocks, and contributes long-term data to understand carbon cycles and impacts of changes like forest management.

Seminar13 Mar 2013 - Sesion 1 - Forest transition in Mekong_ by Xu Jianchu

Forest, Trees and Agroforestry - Component 3: Landscape Management

China initiated the largest forest conservation programs in the world. Chinese forest policies also contributed to increasing forest/tree cover in Yunnan province, Southwest China. We mapped forest cover in Yunnan, Mekong region using satellite imagery. We reconstructed the forest transition curve through narratives since the Great Leap Forward that started in 1958, as well as data from socioeconomic census since 1990s. Our results suggest that the increase in tree cover at the end of the last century was initiated by government policies that encompass regulative approaches as well as incentive payments for tree planting on sloping land, as well as market-driven plantation economy. Local trajectories of forest cover change hence resulted from a combination of exogenous policy-induced incentive payments and endogenous adaptation of land use strategies to changing market conditions. While policies facilitated the increase of tree cover in Yunnan, the degradation of natural forests often continued unabated. Local differences in factor endowments and the uneven geographic distribution of policy support contributed to considerable variation in the pathways to the forest transition, the shape of the forest transition curve, and the environmental and economic outcomes among villages. A better understanding of these processes is paramount to design incentive schemes that stimulate sustainable land use transitions.

1) The document describes a segmentation algorithm for polarimetric SAR (PolSAR) data that can model both scalar-texture and multi-texture scattering. 2) The algorithm uses log-cumulants and hypothesis testing to determine whether a scalar-texture or dual-texture model best fits the data within each segment. 3) The algorithm is tested on simulated multi-texture PolSAR data and is shown to accurately segment the classes and estimate their texture parameters. However, when applied to real data sets, the algorithm only finds the simpler scalar-texture case.

The document summarizes research using SBAS-DInSAR (Small BAseline Subset differential interferometric synthetic aperture radar) techniques to analyze ground deformation at Mt. Etna volcano in Italy over the last 18 years using ERS and ENVISAT satellite data. The analysis revealed three main deformation processes: inflation of the volcanic edifice, subsidence of sectors on the eastern flank due to gravitational spreading, and deflation-inflation cycles associated with eruptive and post-eruptive activity. More recent analysis using higher resolution COSMO-SkyMed data from 2009-2010 detected deformation related to faults and a 2010 earthquake more precisely than lower resolution ENVISAT data.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
