Established in this standard are criteria for variable selection, performance, design, and qualification of accident monitoring instrumentation for anticipated operational, design basis events and severe accidents.
The Ocean Observatories Initiative (OOI) consists of seven research sites collecting ocean, seafloor, and meteorological data in the world's oceans, extending from the Irminger Sea to the Southern Ocean, and the East and West coasts of the United States. The Ocean Observatories Data Evaluation Team is part of the Cyberinfrastructure group at Rutgers University, tasked with reviewing the oceanographic...
Marine organisms such as phytoplankton and zooplankton are sensitive to the spatial and temporal patchiness of their ecosystems. Properties such as temperature can greatly influence their movement, growth, and survivability. Current efforts towards patch detection have focused on satellite, seaglider, and CTD data of open ocean hydrodynamics. This project aims to tackle an insufficiently studied area...
Arctic and subarctic conditions represent some of the most challenging environments to make long-term in situ oceanographic measurements. These areas bring the normal challenges of deep water, turbidity, uncertain bottom types and, in areas such as Cook Inlet, some of the world's largest tidal height changes and tidal currents. This paired with the presence of sea ice, which can be up to tens of meters...
An AML Oceanographic cabled ultraviolet (CUV) light was tested for effectiveness at preventing biofouling in an estuarine setting. The CUV was deployed twice at the US Geological Survey Pearl River site 02492620 at Stennis Space Center, Mississippi. One six week field deployment was during winter conditions (November 12th 2015 to January 5th 2016) and the other during summer conditions (June 8th to...
Moorings with a subsurface float or a benthic lander with onboard positive buoyancy are often coupled to a heavier expendable iron anchor to hold position on the seafloor. Releasing the weight is the critical first step of a mooring or benthic lander recovery. This paper describes a hierarchal selection process to identify the optimal acoustic release configuration for an application.
In 2015, the Hanna Shoal region of the Chukchi Sea shallower than the 40 m isobath was withdrawn from outer continental shelf oil and gas exploration, a move the White House noted was designed to protect areas of “critical importance … for marine mammals, other wildlife, and wildlife habitat”. Arctic regions are projected to strongly manifest impacts of an altered climate and subsurface moored continuous...
Real-time quality control (qc) of oceanographic data is usually accomplished by testing data points against a variety of conditions to identify the quality of the data. Since 2012, the U.S. Integrated Observing System (U.S IOOS®) Program Office Quality Assurance/Quality Control of Real-Time Oceanographic Data (Qartod) Project has worked with the ocean-observing community both nationally and internationally...
The Ocean Observatories Initiative (OOI) is a project funded by the National Science Foundation which provides over 100,000 data products. OOI Cyberinfrastructure takes a two-pronged approach to data quality control: system level and human-in-the-loop. With system level, the system runs datasets through a series of six algorithms: global range, local range, stuck value, gradient, trend, and spike...
The QARTOD methodology of a standard sequential string of tests on individual measurements has high applicability to constrained data systems. The QARTOD methodology has the benefit of a coherent and replicable test structure that enables relatively easy expansion into new measurements. However, as data streams become more complex the series of tests described becomes increasingly difficult to analyse...
Ocean Networks Canada (ONC) is a not-for-profit society that operates and manages innovative cabled observatories which supply continuous power and Internet connectivity to scientific instruments located in coastal, deep-ocean, and Arctic environments. The data from the instruments are archived, quality-controlled, and made freely available to researchers, educators, and the public. The Oceans 2.0...
A Doppler velocity log sonar measures the relative velocity between an instrument and the bottom of a body of water by estimating the Doppler shift of back-scattered sound in multiple beams that point in different directions. The long-term-velocity accuracy of phased-array Doppler velocity logs contains errors including terrain bias, absorption bias, side-lobe coupling, and element spacing error....
With harsh Arctic conditions prohibiting easy, year-round access to subsea assets due to surface ice and weather conditions comes the need to create subsea monitoring technologies capable of reliably surviving long term deployments with little or no intervention. High capacity battery pods and UPSs provide an ideal power delivery method for subsea systems when surface ice and inclement weather precludes...
In 2005 the Department of the Interior, through the Minerals Management Service (MMS), issued a Notice to Lessees (NTL No. 2005-G05) requiring collection of ocean current speed and direction profiles in active oil and gas exploration and production sites. The NTL stipulates that ocean current profiles be collected down to 1000 meters (from ∼ 30 meters) at a minimum of 20 minute intervals and be delivered...
Ocean Networks Canada submitted a proposal to Western Economic Diversification Canada (WED) in 2014 to develop ocean monitoring infrastructure using advanced sensing technologies in areas critical to BC's economic future, such as the proposed LNG facilities at Campbell River, and the ports of Kitimat and Prince Rupert. The proposed infrastructure included technology related to monitoring maritime...
Monitoring the vast expanse of oceans presents a daunting challenge: how to take sufficient high-quality measurements with a relatively small group of specialized scientists and limited resources. Despite advances in remote sensing and autonomous technology, the oceans remain under-explored and under-sampled. One solution for addressing this challenge is to rely on citizen scientists, people outside...
We introduce Kara1k, a new musical dataset composed of 2,000 analyzed songs thanks to a partnership with a karaoke company. The dataset is divided into 1,000 cover songs provided by Recisio Karafun application1, and the corresponding 1,000 songs by the original artists. Kara1k is mainly dedicated toward cover song identification and singing voice analysis. For both tasks, it offers novel approaches,...
The domain of minimally invasive surgery has recently attracted attention from the Multimedia community due to the fact that systematic video documentation is on the rise in this medical field. The vastly growing volumes of video archives demand for effective and efficient techniques to retrieve specific information from large video collections with visually very homogeneous content. One specific...
Traditional video mashup and summarization methods assume that all video clips have common audio, but with varying quality. Hence, selecting the best quality audio is sufficient. In this work we explore a new scenario in which a single person plays each instrument one by one, leading to multi-view video clips, but each video clip having only partial audio, e.g. a single instrument or vocal. To get...
We present Geographic Information System model, which is developed on the basis of metasystem approach and it is focused on application as monitoring system of complex object. The model is described on the basis of set-theoretic approach, functions according to scenarios, integrates, processes and monitors the space-time and coordinate information. The problem of acquisition and reversible compression...
