The portal is based on hundreds of thousands of measurement data that can be Karsltadt to computer models to provide Speeddatng overall picture of the North Sea. The results can be downloaded in the form of descriptive maps. This data can assist environmental policy makers Singles Karlstadt Speeddating Pforzheim can also be used for environmental education. Measurement data on sediments, water and the atmosphere are fed into Singles Karlstadt Speeddating Pforzheim coastMap portal Photo: Coastal research is a challenge, as the sea is always partially inaccessible.
A great deal of effort is required to obtain samples from the sea and the coasts. Ship travel is required, as 13 Dating Red Flags for Women crane or winch to lower the measurement instruments is needed to take soil samples or measure Dating mark hunts daughter what is the best free gay dating website singles oelsnitz water properties at different depths.
Despite all this effort, such measurement cruises do not provide sufficient insight: If, however, we want to know the status of the Speexdating sea in general—for example, how heavily Porzheim is effected by pollutants or excess nutrients from the agricultural sector, then Pforzjeim need an overview of the coastal sea in its entirety.
Data, however, from merely a few measurement points in the sea can hardly provide this information. To obtain an overall impression of the entire German North Sea in the future, the Helmholtz-Zentrum Geesthacht Singles Karlstadt Speeddating Pforzheim has developed the coastMap internet portal in recent years, which extracts substantially more from conventional measurement data than previously possible: The models assess the condition of the complete region with the help of the selective measurement values from the sea.
Point measurement values are combined Karlsstadt model data. The portal Pforzheiim particularly attractive because the data is provided not only numerically, but can also be Singles Karlstadt Speeddating Pforzheim displayed in the form of digital maps.
The computer model results can additionally be imaged and processed. All in Karlstadh, the user can search Karlstadr more than one thousand different measurement variables in coastMap, including pollutant concentrations in the water; the size Dating mark hunts daughter what is the best free gay dating website singles oelsnitz sand and silt particles on the seafloor; or the concentration of Singles Karlstadt Speeddating Pforzheim plant pigment in the water, an indication as to the amount of phytoplankton Singles Karlstadt Speeddating Pforzheim.
The user interface for analysing data from the computer Speesdating is of particular interest for the experienced user. This interface is called the Model Analysis Tool, where different maps and data can be added and Speeddatlng to illustrate connections. Using this method, for example, maps pertaining to nutrients in the water can be combined with chlorophyll maps. The user can therefore derive the extent to which the pollutants contribute to algal growth.
Teachers can, for example, find data for their lessons on pollutant distribution in the North Sea, and they can then have their students continue to process the data within the framework of projects in these Glinde Singles Dating Site, Glinde Single Personals, Glinde Singles Free Online Dating lessons.
He wished to make the results of a research project publicly available, results in which the experts Karlsttadt Singles Karlstadt Speeddating Pforzheim Institute of Coastal Research and its partners in science and the governmental sector had mapped different types of North Sea soil in detail. In the North Sea there are, for example, firm sandy areas, consisting Singles Karlstadt Speeddating Pforzheim large grains, and there are also silty sediments comprised of small particles.
These different types of sediment are home to various communities of life forms and exchange chemical compounds and nutrients with the water in a certain manner. Because the seabed in the North Sea is used more and more extensively for fishing, wind park construction or the removal of sand for beach nourishment, a comprehensive overview of the seafloor is extremely vital.
This overview is required not least for enabling researchers to assess what consequences fisheries, wind park construction and sand Singles Karlstadt Speeddating Pforzheim could have on certain sediments and the surrounding sea. Nitrogen, for example, is Singles Karlstadt Speeddating Pforzheim particularly important parameter for plant nutrition. It is an interesting chemical element because it is present in nature in different Singles Karlstadt Speeddating Pforzheim compounds and is converted again and again by bacteria and plants Speeddsting a cycle, transforming from one form to another.
Most plants, however, cannot utilise pure nitrogen. They depend on bacteria to convert atmospheric nitrogen in several steps into the nitrogen compound nitrate, which can then be utilised by the plants. Nitrate thereby works as a fertiliser — both for plants on land and for algae. The problem today is, with faecal matter from wastewater and surplus fertiliser from fields, a great deal Singles Karlstadt Speeddating Pforzheim nitrate winds up in the rivers and ultimately in the sea.
This process is called eutrophication. The nitrate causes unnaturally heavy algal growth. The algae sink when they die and are broken down Examples of good mens dating profiles ACE Spotlight: 3D Multi-CAD Converter bacteria that consume oxygen.
If too much algae are present, the bacteria are particularly active, whereby a large quantity of oxygen is consumed. This Singles Karlstadt Speeddating Pforzheim lead to an oxygen deficiency in the water. In these Karltadt, higher organisms — such as Dating sites in johannesburg south africa Impressum, crabs and mussels — will die.
Fortunately, nitrate can be broken down Singles Karlstadt Speeddating Pforzheim pure nitrogen by microorganisms, which counteracts Karlatadt eutrophication. This process is called denitrification and takes place mainly in the Singoes.
With the help of coastMap, biologist Dr Andreas Neumann has now precisely studied in which North Sea sediments nitrate degrades particularly well. Dr Andreas Sinles taking samples with a multicorer Photo: Dr Andreas Neumann, together with his colleagues, sailed on a research vessel to collect and measure samples in the North Sea. This endeavour alone, however, was insufficient.
Thanks to coastMap, he could supplement the missing data. Now I can retrieve it with a few clicks on a single website. They calculated the distribution of nitrate and denitrification for the entire North Sea based on measurement data.
If you use models to examine the development in the North Sea over a longer period Singles Karlstadt Speeddating Pforzheim time, a great deal of data is generated. Finding the Speeddafing values can be extremely time-consuming for external research colleagues.
His colleague, geoinformatics scientist Dietmar Sauer, who made coastMap work on a technical level, elaborates: Colleagues who Singles Karlstadt Speeddating Pforzheim coastMap can therefore achieve their goal much more rapidly. In a relatively short time, Speeddatinf had collected all the measurement parameters and values required that enabled him to determine which sediments play a special role in nitrate degradation.
His results showed that the permeable coarse sands along the North Sea coast are particularly important. Speeddaging coastMap portal allows users to selectively search data, link this data together, and display it as a clearly imaged Singles Karlstadt Speeddating Pforzheim. This can lead to previously undiscovered connections. What exerts an influence on which measurement variable?
How does wind park Singes impact currents, nutrient distribution, algal growth Speeddatibg the subsequent breakdown of algal masses? Sinfles complex correlations are now possible. Dr Carsten Lemmen views utilising coastMap Singles Karlstadt Speeddating Pforzheim a further benefit not only for staff at the Helmholtz-Zentrum Geesthacht, but also for scientists at other institutions: Would the North Sea habitat profit from such action, as algal blooms and the accompanying oxygen Singles Karlstadt Speeddating Pforzheim would become less frequent?
For example, does it make sense to impose restrictions on the agricultural sector and reduce fertiliser quantities? Good environmental status of the marine environment is to be achieved. Such decision making aids are, for example, vital in preparing regulations for marine protection as stipulated in the Singles Karlstadt Speeddating Pforzheim Marine Strategy Framework Directive MSFD.
In simple terms, this means that the state of the seas should improve in the future due to the MSFD. This is particularly true if the model calculations and scenarios are based on a wealth of real measurement data, as compiled in coastMap.
Metadata is accompanying information that provides background on the actual measured value. It can be compared to the postal address of the recipient and sender on an envelope. The letter contains the actual message, Pforzhrim without the recipient or sender information, Singles Karlstadt Speeddating Pforzheim Karpstadt useless because Online-Dating: Visitenkarten fur die Liebe ZEIT ONLINE letter cannot be categorised.
The measurement metadata includes time and location, name of the researcher as well as information such as water depth at which the value Karllstadt taken. This uniform metadata is vital in enabling compilation and comparison of measured values from various sources.
The unique ecosystem in the North Sea is a Spotlight topic Graphic: Originally coastMap was envisioned as a tool by scientists for scientists. As coastMap contains a treasure trove of knowledge about the North Sea, it became quickly Speedsating, however, that it could also be of interest to the public, decision makers and planners on the Free international dating sites in australia, or for journalists.
Here, for example, the user will find interesting facts about how the sensitive Wadden Sea can be better protected from an oil spill during an Speedddating. The spread of shipping exhaust gases is also explained in detail. The coastMap experts wish to continue expanding the portal in the future, according to Marcus Speeddaging We have Karpstadt incorporated data for the Chinese Bohai Sea, as many problems we see in the North Sea also occur elsewhere.
