This thesis examines new methods for monitoring two species of murrelets - marbled murrelets and Kittlitz's murrelets - in Alaska. The author tested the effectiveness of marine radar surveys and autonomous acoustic monitoring to assess population size, trends, and distributions. Autonomous acoustic sensors provided a reliable index of marbled murrelet abundance and detected similar levels of calling as human observers. Radar surveys identified prolonged morning flight activity at high latitudes and a clear seasonal trend in activity. The author recommends integrating these new remote sensing tools into existing monitoring programs to increase effectiveness and reduce costs.

This document provides a summary of key developments regarding ocean noise science and regulation in 2007. Some highlights include the Marine Mammal Commission's report on managing ocean noise which called for improved research coordination and regulation of unmanaged noise sources. Research using DTAGs provided new insights into how moderate noise levels can disrupt whale foraging and behavior. Issues around Navy sonar use and its impacts on whales continued to be litigated. Chronic exposure to moderate noise levels was recognized as a growing concern, with studies finding it can damage whale hearing and alter behavior. Shipping noise was a major focus, with research exploring how it dominates ambient noise over large areas and efforts toward developing quieter ship designs and operations. Whale watching and recreational boating noise
1) Researchers tested an acoustic tag tracking system in a hydroelectric dam tailrace to detect tagged fish. They performed tests by towing an active acoustic tag behind a boat to test array coverage and tracking performance.
2) The initial tests determined that the 5ms coded pulse from the tags had the greatest detection range and that all hydrophones were functional with sufficient detection range in the noisy tailrace conditions.
3) Figure 6 documents the procedures used to test tag tracking results in the tailrace, which included programming tags with different signal types and determining the most detectable signal for tracking fish.

This document compares three methods for monitoring populations of Brachyramphus murrelets in Alaska: radar surveys, audio-visual surveys, and autonomous acoustic recording. The study tested these three methods at multiple sites in the Kodiak Archipelago from 2010-2012. Radar detected the largest number of murrelets but could not distinguish between species and was unreliable in high winds. Audio-visual surveys allowed for species identification but had a smaller detection area. Autonomous acoustic recording provided continuous monitoring of vocal activity at lower cost than the other methods. No single method was best and the document recommends using a combination of all three for comprehensive population monitoring and habitat studies of Brachyramphus murrelets in Alaska.
Mobile sailing robot for automatic estimation of fish density and monitoring ...Mateusz383
ntroduction
The paper presents the methodology and the algorithm developed to analyze sonar images focused on fish detection in small water bodies and measurement of their parameters: volume, depth and the GPS location. The final results are stored in a table and can be exported to any numerical environment for further analysis.
Material and method
The measurement method for estimating the number of fish using the automatic robot is based on a sequential calculation of the number of occurrences of fish on the set trajectory. The data analysis from the sonar concerned automatic recognition of fish using the methods of image analysis and processing.
Results
Image analysis algorithm, a mobile robot together with its control in the 2.4 GHz band and full cryptographic communication with the data archiving station was developed as part of this study. For the three model fish ponds where verification of fish catches was carried out (548, 171 and 226 individuals), the measurement error for the described method was not exceeded 8%.
Summary
Created robot together with the developed software has features for remote work also in the variety of harsh weather and environmental conditions, is fully automated and can be remotely controlled using Internet. Designed system enables fish spatial location (GPS coordinates and the depth). The purpose of the robot is a non-invasive measurement of the number of fish in water reservoirs and a measurement of the quality of drinking water consumed by humans, especially in situations where local sources of pollution could have a significant impact on the quality of water collected for water treatment for people and when getting to these places is difficult. The systematically used robot equipped with the appropriate sensors, can be part of early warning system against the pollution of water used by humans (drinking water, natural swimming pools) which can be dangerous for their health.

Ocean Dynamics and Sediment Transport Measuring Acoustic and Optical InstrumentsIRJET Journal
This document discusses instruments used to measure ocean dynamics and sediment transport. It describes acoustic instruments like the Acoustic Doppler Current Profiler (ADCP) which uses Doppler shift from sound waves to measure ocean currents and velocity profiles with 1% accuracy. Optical instruments are also discussed, such as the optical backscatter sensor which uses infrared light scattering to measure turbidity and suspended solids above 1 kg/m3. The document analyzes these acoustic and optical techniques to effectively measure parameters like velocity, turbidity, and sediment size/concentration for understanding coastal hydrodynamics and sediment transport.
This document discusses key threats to Hawaiian reefs from various human activities and natural stressors. It provides details on potential data sources that could be used to map the spatial distribution and intensity of each threat, such as sediment export models, land use maps, commercial fishing records, buoy locations, and satellite sea surface temperature data. The goal is to develop comprehensive spatial datasets characterizing multiple threats to better understand their combined impacts and inform management decisions.
The document discusses wildlife mortality along Utah's highways and efforts to minimize it. It outlines the role of the Division of Wildlife Resources in working with the Utah Department of Transportation and others to identify locations with high deer-vehicle collisions and implement sufficient wildlife crossing structures. It provides details on the statewide roadkill database and recent wildlife crossing projects. It also describes wildlife crossing guidelines and the ongoing wildlife crossing camera study aimed at determining which crossing types are most effective for wildlife.

This document discusses how wireless sensor networks are enabling new applications in ecology and environmental monitoring by allowing data collection over larger spatial and temporal scales than previously possible. It provides examples of existing uses, including monitoring lake conditions in Taiwan and Wisconsin simultaneously, increased sampling of stream chemistry during floods, and acoustic monitoring of bird populations over large forest areas. Wireless sensor networks have the potential to revolutionize ecological study by facilitating intensive, long-term sampling over large areas and automated collection of new data types like sound and video. This promises to reveal ecosystem phenomena not previously observable.
This document presents an underwater acoustic sensor network for early warning generation of tsunamis. It discusses flaws in existing tsunami early warning systems, and proposes an integrated system using underwater sensor networks, satellites, and terrestrial communication networks.

Prototype HTI acoustic predation tags designed to indicate an acoustic tagged fish had been eaten by a predator were tested by DWR and Reclamation staff at the Tracy Fish Collection Facility’s Tracy Aquaculture Facility. Six adult striped bass (> 400 mm FL) were each sequentially fed ten Chinook salmon with implanted
predation tags. Initial feeding time to predation tag activation time, was recorded for 54 of the 60 predation tags (6 tags failed to activate). Average time for a tag to activate was 57:30:59 (range: 22:18:00 to 140:01:00). Control predation tags (tags turned on but
not in predation indication mode) were surgically implanted in to two groups of ten control Chinook salmon. The control Chinook salmon were held for at least 30 days post‐surgery to check for effects of the predation tag on fish health and recovery from
surgery. There were 3 mortalities within 2 weeks after the surgical implantation. There were no false positives in the control fish, meaning that the tags did not activate in the target species. Predation tags are a promising new technology for determining the fate of acoustically‐tagged salmonids. Once field tested, these
tags could be used in many applications to understand the magnitude of predator impacts on salmonids near
manmade structures.

In the Sacramento‐San Joaquin Delta, several salmonid
species are listed as threatened or endangered. One potential cause of lower juvenile salmonid survival may be striped bass predation. Acoustic tags are routinely used to estimate survival by releasing and detecting tagged juvenile salmonids with the assumption that tagged salmonids are not consumed by other fishes. If this assumption is violated, salmonid survival estimates may be misinterpreted. A key consideration is the time taken by an acoustic tag to pass through the digestive tract of a predatory fish. To measure evacuation rates, acoustically tagged juvenile Chinook salmon were euthanized, then tethered and fed to free swimming (acoustically tagged and wild) striped bass in the primary channel of the Tracy Fish Collection Facility. Confirmation of time at predation event was determined by analysis of 2D acoustics tracks. The amount of time required for an acoustic tag to pass through the digestive tract of a striped bass estimated the evacuation rate. Mean tag evacuation time was 1.8 d (n = 14; SD = 0.49; range = 1.2 to 2.7). Mean tagged salmon was 146.6 mm FL (n = 14; SD = 7.6; range = 131 to 165). Results indicated free swimming striped bass evacuate small acoustic tags (0.5 g) relatively quickly in 22°C water. By comparison, a study investigating predation events using larger tags (1.1 g) on relatively sedentary laboratory fish held in 16°C had greater
evacuation times. This feasibility study demonstrated acoustic tags can provide information about predation and gut evacuation in free‐swimming predatory fish. As a result, the Bureau of Reclamation extended testing of predation and gut evacuation rates to include temperature variation and food availability levels in the Tracy Fish Collection Facility Primary Channel, starting
late 2013.

This study tracked the behavior and fates of Chinook salmon, steelhead, and striped bass acoustically tagged and released at the Tracy Fish Collection Facility in 2013. The goals were to quantify fish survival and facility efficiency. A total of 133 salmonids and 36 striped bass were released under different flow conditions and their movement, salvage rates, predation, and losses were monitored. The key findings were that Chinook salmon were more likely to enter the facility at mid-high flows while steelhead behavior was more variable, with more upstream movement away from the facility and lower predation and louver loss rates than Chinook salmon.

The optimal management of salmonids in the Delta requires that the true fate of each tagged fish be known. Loss of tagged salmonids due to predation has been estimated to be as high as 65% (Vogel 2011). This data is ambiguous at best and survival estimates and behavioral results are biased. Hydroacoustic
Technology Incorporated (HTI) has developed a prototype acoustic tag that has the ability to signal when a tagged fish has been eaten by a predatory fish. DWR and USBR staff were given 100 prototype predation tags for efficacy testing in live Chinook salmon.
This presentation was given by Kevin Kumagai, Senior Fisheries Biologist at HTI Hydroacoustic Technology at the American Fisheries Society's Annual Meeting in Little Rock, Arkansas in September 2013.
Overview:
Acoustic tags can provide information about fish populations. For example, presence/absence of fish. If detections are uniformly spaced to a high level of precision, these detections can assess fish behavior. Example behaviors include: moving toward and away, holding, downstream migration, searching, fish passage, predator avoidance, predation, simultaneous tags, tag defection. The HTI Predation Tag verifies predation via a unique modification in the tag signal while maintaining individual fish ID. It provides a tool to directly measure predation and allows evaluation of behavior-based predation techniques. Currently in testing by CDWR and BOR in 2013 (Afentoulis et al., 2013), it is being field tested in 2014. Being able to monitor predation dynamics, especially as it relates to threatened or endangered species (e.g., salmonids) will provide tremendous insights to better fisheries management.
Acoustic tags can provide information about fish populations beyond just presence/absence. If detections are uniformly spaced with high precision, fish behaviors like moving towards and away from objects, holding positions, defecating, downstream migration, fish passage, searching, and predator avoidance can be assessed. Examples showed tagged fish exhibiting these behaviors as detected by multiple precisely positioned hydrophones.
Acoustic tagging studies routinely provide information about fish presence and absence. This detection information can be combined into a chronology of time-stamped tag detections to estimate fish survival and fish passage rates, among others. Beyond this simple detection data, if tag transmissions are uniformly spaced with a high level of precision the detection time series can be used to assess fish behavior and events. Fish behaviors range from simple to complex and some of these behaviors can be interpreted from acoustic tag detection time-series. From single receivers, simple movement toward or away can determine directionality, observed cessation of tag movement can be interpreted as holding behavior, or extended lack of movement as fish mortality or tag defecation following predation. Multiple receiver arrays providing precise measures of two dimensional and three dimensional fish movement can resolve patterns of detections that indicate active fish migration from more wandering movements indicative of resident species or predators. As more and larger fish populations are studied, more acoustically-tagged fish will interact, increasing the opportunity for accurate interpretation of observed behaviors. Quantifiable behaviors include predator avoidance, schooling/shoaling, predation, and tag defecation. Behavior can be further interpreted when tag detection histories are observed and analyzed in relation to each other and not as isolated tag detections.
A marine bioacoustics workshop at University of Washington's Friday Harbor Labs tracking the secret lives of shrimp and crab in the Puget Sound with Dr. Charles Greene of Cornell University.
This document discusses using acoustic telemetry to study predation on juvenile salmonids in the Sacramento River Delta. Fine-scale fish tracking data can identify predatory behaviors and potential predation events. Predators exhibit margin-oriented movement while salmon smolts travel through open water. Overlapping tracks or tags becoming stationary may indicate predation. Behavioral metrics like sinuosity and speed distinguish predators from migrating salmon under different water velocity conditions. Quantifying fish behaviors aids understanding predation impacts on salmon survival in the Delta.
This document summarizes an acoustic tag study conducted at the Seattle Aquarium in 2011. Three species - Canary Rockfish, Yellowtail Rockfish, and Coho Salmon - were implanted with acoustic tags and their 3D movements were monitored and displayed in real-time using an acoustic telemetry system. Over 3,100 people attended the public event to view the real-time 3D tracks. The study demonstrated the ability to simultaneously monitor multiple species and observe species-specific behaviors. Real-time acoustic tagging provides valuable information about animal movement and interactions in both marine and freshwater environments.
The Southeast Regional Acoustics Consortium (SEAC) met in March 2012 at Florida International University bringing together academic institutions, federal and regional fisheries and environmental management agencies, and private industry that conduct active acoustics research in the coastal environments of the US from North Carolina to Texas and the US Caribbean. Informal presentations and discussions highlighted the latest tools for fisheries research, organized around high-priority research objectives and management drivers (e.g., stock assessment improvements, integrated ecosystem assessments) and HTI’s Pat Nealson conducted a presentation to help demystify FM Slide/Chirp signals in hydroacoustics for fisheries assessments.
This document discusses the use of acoustic tags and tracking systems to study fish behavior and passage. It provides details on:
1) How acoustic tags work by transmitting coded acoustic pulses that are detected by hydrophones to determine a fish's location in 3D.
2) Examples of studies using this technology including tracking fish passage in dams on the Columbia and Snake Rivers, collecting behavioral data on fish milling and interaction with flows, and aquaculture applications.
3) The components of an acoustic tag tracking system including the tags, hydrophones, receivers, and data processing used to triangulate fish positions over time for tracking and analysis of movement patterns.
Climate Impact of Software Testing at Nordic Testing DaysKari 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.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Removing Uninteresting Bytes in Software FuzzingAftab 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.
