    Get PDF
    The New Hampshire (NH) Volunteer Beach Profiling Monitoring Program (VBPMP) monitors beach elevation profiles at multiple stations along the NH Atlantic coast on a near-monthly basis using the Emery method. The program grew from three monitoring stations in 2016-2017 to thirteen stations across six beaches in 2018, with an additional station added in 2022. The overarching goal of the VBPMP is to assess the stability of New Hampshire’s Atlantic beaches over multiple years to determine seasonal changes and long-term trends using citizen science methods. Included in the assessment of beach stability are erosional or accretional trends, response to storms, and comparisons between beaches with differing morphology, sediments, and infrastructure (e.g., seawalls or dunes). Presented in this report are the methods used by the NH VBPMP for establishing profile stations, collecting beach elevation profiles based on the Emery method, recording, and uploading field data, and taking field photographs. The methods used for processing profile data after collection by volunteers is also described, including data review and quality assurance, datum corrections, plotting elevation profiles, sediment volume computation, and determination of mean profile elevations. Finally, examples of data products created for sharing with the public are presented

    Wireless Sensor Networks are often deployed in great numbers spanning large, sometimes hard to reach and hostile, areas with the aim of monitoring environmental conditions through the use of different sensors. Due to decreasing costs of ownership (e.g. non-proprietary protocols), recent advances in processor, radio, and memory technologies and the engineering of increasingly smaller sensing devices, the availability and area of application for wireless sensor networks have steadily been increasing. Sigma Technology Development Stockholm AB raised the question as to whether a wireless sensor network, running an open-source operating system and communicating over IPv6, could be used in the field of smart autonomous irrigation? The company also required a proof-of-concept system for demonstration purposes and to identify if the design choices made were suitable for an actual implementation. There are numerous of design decisions that have to be made when constructing an irrigation system: the back-end set-up, which irrigation algorithms to use, what hardware to choose and how to communicate? This thesis therefore focuses on the overall system design of a wireless sensor network in the field of irrigation and highlights the trade-offs being made and their pros and cons. Two improvements related to the existing technology and the proof-of-concept system are presented in this thesis. Firstly, the recommendation to use clustered self-healing routing despite claimed power consumption issues. Secondly, a new technique to minimize power consumption, by dynamically changing the sleep interval on the sensor nodes with the help of weather data. Furthermore, the proof-of-concept system is constructed and analysed to assess whether the system design choices made are valid for a real-life deployment.TrĂ„dlösa sensor nĂ€tverk anvĂ€nds för att övervaka lokala miljöförĂ€ndringar med hjĂ€lp av olika sorters sensorer. PĂ„ grund av nedĂ„tgĂ„ende driftkostnader (ökad tillgĂ€nglighet av open-source mjukvara) och framsteg inom processor-, radio-, och datorminnesteknolgi har bĂ„de tillgĂ€ngligheten och anvĂ€ndningsomrĂ„dena för trĂ„dlösa sensornĂ€tverk stadigt ökat. Sigma Technology Development AB stĂ€llde frĂ„gan huruvida ett trĂ„dlöst sensornĂ€tverk, som anvĂ€nder sig av ett open-source operativsystem och kommunicerar över IPv6, kunde anvĂ€ndas inom smart konstbevattning? Företaget ville Ă€ven att ett proof-ofconcept system utvecklades för demonstration samt för att kunna avgöra om de designval som gjorts Ă€r lĂ€mpliga att anvĂ€nda i en verklig implementation. Det finns en mĂ€ngd designval som mĂ„ste göras nĂ€r man konstruerar ett bevattningsystem: back-end lösningen, vilka bevattningsalogritmer som ska anvĂ€ndas, vilken hĂ„rdvara som ska anvĂ€ndas samt hur kommunikationen mellan noderna ska upprĂ€ttas? Det hĂ€r examensarbetet fokuserar dĂ€rför pĂ„ den övergripande systemdesigen av ett trĂ„dlöst sensornĂ€tverk inom konstbevattning, utvĂ€rderar och avgör vilka kompromisser som mĂ„ste göras samt för- och nackdelarna med dessa val. Examensarbetet presenterar vidare tvĂ„ förbĂ€ttringar pĂ„ det utvecklade konceptsystemet som inte heller finns pĂ„ marknanden. Först rekommenderas anvĂ€ndandet av robusta sjĂ€lvlĂ€kande routing protokoll trots pĂ„stĂ„dda energiförbrukningsproblem. Sedan föreslĂ„s Ă€ven en teknik som minimerar energiĂ„tgĂ„ngen genom att dynamiskt Ă€ndra hur lĂ€nge sensornoden befinner sig i ’sleep mode’, detta med hjĂ€lp av insamlad vĂ€derdata. Slutligen sĂ„ konstrueras och analyseras proof-of-concept systemet för att utvĂ€rdera om dessa designval Ă€r lĂ€mpliga för en implementering i det verkliga livet

    ARGOS policy brief on semantic interoperability

    Semantic interoperability requires the use of standards, not only for Electronic Health Record (EHR) data to be transferred and structurally mapped into a receiving repository, but also for the clinical content of the EHR to be interpreted in conformity with the original meanings intended by its authors. Accurate and complete clinical documentation, faithful to the patient’s situation, and interoperability between systems, require widespread and dependable access to published and maintained collections of coherent and quality-assured semantic resources, including models such as archetypes and templates that would (1) provide clinical context, (2) be mapped to interoperability standards for EHR data, (3) be linked to well specified, multi-lingual terminology value sets, and (4) be derived from high quality ontologies. Wide-scale engagement with professional bodies, globally, is needed to develop these clinical information standards

    Ocean Industries and Marine Planning

    Get PDF
    Marine planning (marine spatial planning/MSP) is under development as a viable tool to address potential user conflicts in the oceans and allow for better management of ocean uses and resources. With marine planning developing in many parts of the world, especially the E.U., U.S. and Australia, it is important for industry to be part of the creation of a shared vision for a marine area, the discussion regarding whether or not to pursue a planning or other improved management effort, and the necessary elements (e.g., outreach, funding, boundaries) of such an effort. World Ocean Council, with funding from the Gordon and Betty Moore Foundation, undertook a project to inform and, as appropriate, engage a diverse range of ocean industries on marine planning and encourage the use of credible science and risk assessment. With information gathered through literature reviews, case studies, interviews, and outreach, this paper presents potential benefits of and concerns regarding marine planning from the ocean business perspective. It also offers considerations for industry to consider its role in marine planning and for planners on how and why to engage the private sector

    Port State Performance Putting Illegal, Unreported and Unregulated Fishing on the Radar

    Get PDF
    Illegal, unreported and unregulated (IUU) fishing is notorious for undermining efforts to manage fisheries sustainably and has detrimental environmental, social and economic consequences. The Pew Environment Group's Port State Performance research focuses on the role that port States play in abating IUU fishing by assessing how effectively they are implementing port State measures. As the situation stands, the current system of port State measures lacks transparency, accountability and global reach, and is thus failing to both close loopholes exploited by IUU operators and keep IUU fish out of ports

    Federal Standardized Health Insurance Plans Could Improve Access to Care without Raising Premiums

    Get PDF
    Health insurance companies should offer plans on the Affordable Care Act marketplaces that cover the cost of basic outpatient care—like primary care, specialty care, and prescription drugs—before people pay off their deductible. The new federal standardized silver plans, released by the Department of Health and Human Services (HHS) earlier this year, will do just that. New, original research shows that federal standardized plans are a good deal for consumers who need a plan that covers basic health care services before they meet their deductible. Our report found that:The federal standardized silver plans would have premiums that are comparable to current silver marketplace plans that cover little to no services before the deductible.Offering these standardized plans could improve access to outpatient care without driving up premiums.Families USA produced the report with Milliman, an independent actuarial firm. Families USA believes that insurers in all 34 states with federally facilitated marketplaces should offer these plans in 2017 so that consumers in these states have access to these plan options. In 2018 and future years, we urge the federal government to require insurers in these states to offer the federal standardized plans
