  • I'd advise you to use this service: ⇒ www.HelpWriting.net ⇐ The price of your order will depend on the deadline and type of paper (e.g. bachelor, undergraduate etc). The more time you have before the deadline - the less price of the order you will have. Thus, this service offers high-quality essays at the optimal price.

  • I’ve personally never heard of companies who can produce a paper for you until word got around among my college groupmates. My professor asked me to write a research paper based on a field I have no idea about. My research skills are also very poor. So, I thought I’d give it a try. I chose a writer who matched my writing style and fulfilled every requirement I proposed. I turned my paper in and I actually got a good grade. I highly recommend ⇒ www.WritePaper.info ⇐

  • If you’re struggling with your assignments like me, check out ⇒ www.HelpWriting.net ⇐. My friend sent me a link to to tis site. This awesome company. After I was continuously complaining to my family and friends about the ordeals of student life. They wrote my entire research paper for me, and it turned out brilliantly. I highly recommend this service to anyone in my shoes. ⇒ www.HelpWriting.net ⇐.

  2. 2. Space as a tool supporting the energy package #EUSpaceWeek !2 Motivation: What drives the need to support our future energy security? Why now? NEGATIVES - Dangerous by-products (CO2, SO2, radioactive) - Fuel transport & sourcing - Questionable security Transitioning towards • Local resource dependence • Different locations demand different technology • Conversion technology unrefined ⟶ energy out? • Variability in resource availability (over varying timescales) • Local environment inter-dependence New sustainable approaches
 to energy generation e.g. wind, solar, ocean, hydro, biomass, • Location-agnostic • Continuous (all day, all night, 24/7) • Instantaneous (to meet demand) • Linear (fuel in ⟶ energy out) • Effectively unlimited
 (assuming fuel provided) e.g. carbon fuels: gas, oil, coal fire powered,
 nuclear fission ⟶ steam turbines Existing traditional energy generators NEW CHALLENGES - Understanding variability of renewable resources - Forecasting short-term for energy grid management - Long term trend changes in resource - Impact of extraction on environment and availability - Lack of data
  3. 3. Space as a tool supporting the energy package #EUSpaceWeek !3 The transition to sustainable energy
 sources is underway. Diverse mix is central to its success. Why Ocean Energy? x3 Oceanenergy • Unobtrusive • Resource: Vast store of energy relative to our global demand • Access: 80% of populations live within 100km of the ocean • Continuity of supply • Space: Oceans cover more that 70% of the Earth’s surface Significant advantages: • Diversity of energetic physical ocean processes to tap into T S waves tidal current • Density: of energy is high OTEC

NEW CHALLENGES - Understanding variability of renewable resources - Forecasting short-term for energy grid management - Long term trend changes in resource - Impact of extraction on environment and availability - Lack of data Importance of ensemble and data assimilation

  7. 7. Caribbean Watch Caribbean watch reports current ocean conditions in the Caribbean Sea, inferred from the Mercator Ocean reanalysis dataset. Separate pages focusing on regions of the Caribbean Sea are linked to below. The regional Caribean basin result is posted daily to the twitter feed ! @caribbean_watch (https://twitter.com/caribbean_watch). Physical oceanographic conditions in the Caribbean Sea are considered. Here we use a combination of data from Mercator Ocean and a state-of-the-art, fine-scale hydrodynamic model of the full Caribbean Sea region using ADCIRC. The former is an operational 1/12º global ocean physics and analysis data set. This assimilates data using the NEMO ocean model (version 3.1, at a horizontal spatial resolution of 1/12º, 3-9 km) from various sources, including satellite and shipboard observations, to give the best, continuous approximation of ocean behaviour in space and time, over the period 2007-2017. Carribbean basin Current conditions Up to date two-hourly mean surface currents of the regional Caribbean Sea, either side of today 26 Jan 2018: from a week ago on 19 Jan 2018 and forecast ten days ahead to 05 Feb 2018. Two-hourly mean surface currents of the Caribbean Sea. Frames move through days of the year. Velocity data is from the Mercator operational 1/12º global ocean physics and analysis data set (Mercator Ocean, 2017). Bathymetry and coastlines determined from GEBCO (2014). To identify the location of shallower waters, a red line marks the 100m depth contour. Available to download here. A forecast of the daily mean surface velocity is also available here. Regions of the Caribbean Sea Further analysis for regions of the Caribbean Sea, including daily-updated current conditions and longer-term annual datasets.
