  • Heat waves and climate change

    There has been a remarkable run of record shattering heat waves in recent years, from the Russian heat wave of 2010 that set forests ablaze to the historic heat wave in Texas in 2011 and the Summer in March in the U.S. Midwest in 2012. These events typify the ongoing trend driven by climate change. Climate change is already affecting extreme weather. The National Academy of Sciences reports that ...

  • Are my STS’s recordable?

    Although we often take it for granted, hearing is one of our most important senses. During infancy and childhood, hearing is vital for the normal development of speech and language. Hearing remains equally important throughout life as it enables us to communicate with friends and colleagues, and allows us to stay connected to and be aware of our environment. The ear is a remarkable structure, ...

  • Heat waves in Central Europe (1991–2006)

    The extreme weather phenomenon of heat waves poses a serious threat to humans and has been shown to contribute to increased sickness rates and even deaths, mostly in large cities. The paper concerns the occurrence of heat waves in Central Europe. Data was collected from five regional weather stations in Budapest, Krakow, Lvov, Prague and Vienna and included records of the average, maximum and ...

  • Arctic warming blamed for dangerous heat waves

    Few people have heard of Rossby waves and even less understand them, but if you are sweltering in an uncomfortably long heat wave, then they could be to blame. New discoveries about what is going on in the atmosphere are helping to explain why heat waves are lasting longer and causing serious damage to humans and the natural world. These events have doubled in ...

  • Warmest Decade on Record Brings Record Temperatures and Weather Extremes

    In recent years weather events have whiplashed between the extremes of heat and cold, flooding and drought. Carbon dioxide and other greenhouse gases—largely from the burning of coal, oil, and natural gas—have loaded up in the atmosphere, heating the planet and pushing humanity onto a climatic seesaw of weather irregularities. High-temperature records in many places are already being ...

  • Stevens Equipment Records Historical Information During Tsunami

    One of the longest lived products in water resource monitoring has been the Stevens’ chart recorder. In fact, the chart recorder, originally invented by Stevens’ founder and namesake J.C. Stevens in 1911, is the product that established Stevens’ leadership in the water monitoring business.  It’s no surprise then that some of these chart recorders have had long service lives and have recorded ...

  • Supporting wave and tidal energy in the UK - an analysis of UK Policy 2000-2009

    In order to stimulate UK based marine energy technology developers, the UK Government launched the Marine Renewables Proving Fund (MRPF) in 2009. This instrument was designed to bridge the gap between early-stage research funding and the recently-criticised Marine Renewables Deployment Fund (MRDF). This paper develops an analysis framework for policy instruments designed to support technology ...

  • Eco-economy indicator: past decade the hottest on record

    The first decade of the twenty-first century was the hottest since recordkeeping began in 1880. With an average global temperature of 14.52 degrees Celsius (58.1 degrees Fahrenheit), this decade was 0.2 degrees Celsius (0.36 degrees Fahrenheit) warmer than any previous decade. The year 2005 was the hottest on record, while 2007 and 2009 tied for second hottest. In fact, 9 of the 10 warmest years ...

  • Why it`s time to get serious about wave power

    For most of us power from the sea means watching waves crashing on a beach or smashing up against a breakwater. But if you want to experience wave power at its most energetic then you need to be offshore. In fact you need to be over one hundred kilometres offshore. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough, some 180Km from land, encountered the ...

  • Introduction to Ground Penetrating Radar (GPR)

    About GPR Ground Penetrating Radar (GPR) is a non-invasive method of material analysis based on transmitting an ultra wide band EM signal into the materials. A part of the EM wave is reflected when it reaches a boundary between two materials with different electrical properties. The reflected signal gets recorded at the source of the EM wave and is displayed for the operator and ...

  • Geotechnical Geophysics: Seismic refraction and refraction microtremor (ReMi) surveys

    ReMi Surveys are superior to MASW Surveys in the following ways: Ambient (ie, traffic and aircraft) “noise” is a hindrance to MASW surveys, yet is readily embraced / utilized by “passive” ReMi surveys Longer ReMi data records (ie, 30 seconds vs 8 seconds or less with MASW) capture lower frequency events We introduce high frequency impulsive energy that ...

  • Decision support system for predicting tsunami characteristics along coastline areas based on database modelling development

    Tsunamis are extraordinary occurrences that are difficult to identify; most of the incidents have no recorded predictions and tsunamis are generally infrequent events with poor data acquisition. The development of a tsunami database system has become important for improving the management of information with regard to a tsunami early warning system for vulnerable communities along coastline ...
