In 2015, the Hanna Shoal region of the Chukchi Sea shallower than the 40 m isobath was withdrawn from outer continental shelf oil and gas exploration, a move the White House noted was designed to protect areas of “critical importance … for marine mammals,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...
Every few hundred years, the Cascadia subduction zone off the coast of the Pacific Northwest hosts devastating earthquakes, and there is a growing awareness of the need to be prepared for these events. An offshore cabled observatory extending the length of the Cascadia subduction zone would enhance the performance of the earthquake and tsunami early warning systems, would enable real time monitoring...
Three sensors, pH, dissolved CO2, and a CTD with a dissolved oxygen sensor were co-located on a submerged platform connected to a buoy platform in the Saanich Inlet close to Patricia Bay near Sidney, British Columbia. The sensors were moored at a depth of 23 metres for one year continuous sampling deployment to assess the ability of these sensors to monitor the edge of a dynamic, dissolved inorganic...
Before the satellite altimetry era, tide gauges are the unique source of information to monitor global sea level rise due to anthropogenic climate change. As sea level changes display regional variability, its global mean can be estimated by averaging trends from good quality tide gauge. This leads to sea level rise rates of 1.65 +/− 0.2 mm/yr during the 20th century. However, this value and the related...
The proposed project shows the results obtained in the implementation and testing in lacustrine and marine environment of a nautical remote controlled vehicle with surface navigation and innovative features Semi-Immersible (SI-USV). This vehicle is based on a pending patent belonging to Palermo University (Patent Pending RM2012A000209 and RM2012A000209) concerning innovative semi-immersible vehicles...
A novel concept of an integrated spectrometric sensor platform is presented in this paper. The design and functioning of the proposed hardware and software for this instrument are discussed and its application prospects are investigated. It is designed to be a compact, portable and remotely operable sensing system, comprising of high resolution spectral and environmental sensors. In addition, it has...
The paper briefly presents the technical and operational details of a series of new sensors and related instrumentation developed by the author and implemented throughout the country to meet the challenging needs of oceanographic investigations taken up by different institutions. Development of sensors with location specific technical features is the basic requirement of successful oceanographic observations...
The Baltic Sea consists of several sub-basins. They all have their own physical characteristics and motion scales. General circulation and meso-scale eddies in the basins are in continuous interaction. Traditional monitoring by research ships, gives a general impression on the conditions, but that impression is not detailed unless towed instruments are used. Gliders have extensively been used for...
In this article the authors examines up-to-date relationship between theory of polymetric measurements and state of art in intelligent robots sensing. The paper contains commentaries about: concepts and axioms of polymetric measurements theory, corresponding monitoring information systems used in different technologies and some prospects for polymetric sensing of intelligent robots. Furthermore they...
This study presents the feasibility of sea waves monitoring using the P(Y) & C/A ReflectOmeter (PYCARO) instrument which employs a novel Global Navigation Satellite Sys tems Reflectometry (GNSS-R) correlation technique. To that end, an experiment over the wave channel surface of the civil engineering school of UPC (Barcelona, Spain) is performed using a signal generator to simulate the GPS satellites...
Decades of technical development in electronics, telecommunication, optics and acoustics measuring techniques have opened new possibilities for multi-parameter monitoring of the marine environment. This conference paper will give examples on how fixed multi-parameter platforms are used in a wide variety of applications ranging from shallow coastal on-line observatories down to measuring in the deepest...
This paper involves a method for height measurement of the virtual objects in a gray-scale image, it is based on the algorithm of level set method through level set function gray gradient changes. This method is adequate on height measurement on calculation and could be used in rich areas such as wave height measurement.
In this paper the potential of COSMO-SkyMed is examined for oil spill detection, focusing on the Adriatic Sea. The low revisit time and the radiometric characteristics of COSMO-SkyMed point to good suitability of the instrument for operational oil spill detection in the area. The possibility of querying Automatic Identification System (AIS) data over the area, with almost no coverage gaps, offers...
The Oceanic Platform of the Canary Islands (PLOCAN) will provide rapid access to great depths at short distance from the shore, accelerating research and the generation of water column and deep-ocean knowledge. The mission of the multidisciplinary observatory is two-fold: the first is to contribute to the monitoring and modeling of coastal, regional and global ocean phenomena and ecosystems at increasing...
Long-term observations conducted with large arrays of tiltmeters deployed in ocean bottom boreholes, on the seafloor, are expected to provide rich information useful in geosciences, social engineering, resource monitoring, and other applications. To facilitate such observations, we designed and built a compact, highly sensitive tiltmeter with sufficient performance, comparable to that of much larger...
The developments of subsea observatories has been addressed by several national and European projects involving Ifremer engineering teams during the last decade. The motivation of scientific research disciplines has been growing during the same period. The coordination of ESONET Network of Excellence has been a unique occasion to analyse the best practices world wide and propose standards and recommendations...
Dissolved greenhouse gas measurements (GHG) are of increasing importance for science, monitoring agencies and industry. Sensors for dissolved carbon dioxide (CO2) and methane (CH4) are applied in a growing number of applications. At the same time the number of mobile platforms deployed in the field is growing. Modern mobile platforms can sample on spatial and temporal scales that previously were not...
Our simple tests and early working experience with the CastAway have shown it to be a versatile tool, useful for quickly and easily obtaining temperature and conductivity profiles in shallow waters. It also seems to meet and may even exceed its stated specifications. We look forward to conducting further tests to perform a more in depth evaluation of the systems technical qualifications.
The recent Gulf of Mexico (GOM) oil tragedy is emphasizing the importance of collecting sound, real-time ocean observations through collaborations of academia, government, and industry. Ocean observing systems (OOS) provide continuous data for various environmental, oceanographic, and atmospheric parameters. Many systems, such as moorings and buoys, are in fixed locations providing excellent time...
The Interactive Graphical Ocean Database System (IGODS) is a complete software solution to support studies of ocean, coastal, and inland waters using profiling instrumentation such as a conductivity-temperature-depth (CTD) instrument. If you routinely conduct surveys where you are profiling at a set of geographic locations, collecting CTD profiles, and perhaps also collecting water samples for additional...
