Collect and provide maritime measurement data

Ensure efficient acquisition of marine measurement data with a suitable data management system

Polar regions and oceans play a vital role in the global climate system. Exploring these regions therefore is of particular importance for decisions to be taken regarding our Earth's climate today and in the future. However, it takes scientists a lot of effort and material input to get to these regions. The frequently harsh and hostile environment put humans and equipment under enormous stress. That makes the data collected there valuable in two respects: collecting them costs a lot of money and time and it may be very difficult or even impossible to get these data a second time.

For this reason, it is essential that the best possible data quality is achieved at the first go and that data losses are prevented. And that is what you need a reliable data management system for, which provides you with top-quality data.

A measurement data management system does more than just collect and archive your measurement data

Scientists, ship owners and users in data centers know full well: marine research – and especially research shipping - imposes special requirements on a measurement data management system. Mind you, the starting point of a sustainable collection and management of precious scientific data of research projects is much earlier than their actual safe acquisition and recording on the research platform and it doesn't end with their long-term archiving on shore: the IT system must be capable of efficiently controlling the processes way before and after the actual expedition.

Top data quality by constant monitoring

One of the important tasks is to correlate the data of different origin. The data are supplied by the sensors of the small or large devices employed, the sensors of the research vehicle used and by the scientists in the form of logged results.

By comparing these data, you can assess their individual quality straightaway. In specific circum-stances, it is even possible to adjust the measurement equipment while the vessel is still travelling or to repeat a measurement then and there. In case of large research vehicles, it's ideal if the analysis can be carried out on the actual vehicle.

An optimum data management system provides various tools to track down sensor errors, sensor failures or potential configuration errors and to have them repaired while still on board:

  • Limit value monitoring
  • Plausibilization functions
  • Options to compare the measurement values of different sources
  • Data transfer for initial analyses on shore or to a different central receiving location

When the system detects an error state, it should immediately inform you by different means, such as:

  • E-mail to the system administrator
  • Alarm prompt in the dashboard
  • Alarm tableau providing data for error analysis

The direct correction of the error state spares you laborious adjustments or even useless data in the aftermath.


Easy integration of any kind of measurement devices

More often than not, measurement devices are custom-made items, special devices or global novelties and are subject to frequent changes. Therefore, it is essential that the system supports your preliminary planning at the best possible rate by providing options to check the devices' master data, to add new master data or to update existing ones. Or your devices have special demands regarding the format of additionally supplied data like time or position: with a suitable measurement data management you can cover all these requirements and it will be easy for you to connect an unlimited number of devices in no time – at best you can do it at any required time and can configure them as required.

Reliable logging of all relevant measurement data

Time and again in the course of your research project there will be events you want to link to your measurement data. For this purpose, it's important that logging these events is easy. If you have the right measurement data management system, it automatically complements the event data with context data like time, position, device used or current station number so that manual input is limited to a minimum. Not only does this save your time, it also minimizes faulty input. In addition to this, you should have the option to derive parameters by combining other parameters using mathematical formulas. When done, you can display your derived values online and store them just like directly measured data.

When it comes to finding the most efficient way to the actual area of research, continuously updated environmental data in synopsis with your planning data are a valuable help. If the information is displayed in interactive maps and clearly arranged dashboards, well-considered decisions that make an expedition a success can be taken in near real-time even before the expedition starts or while it is still underway.

Unlimited distribution and secure archiving of your measurement data

You want an uncomplicated way to place your data available and share them. No matter whether you want to send your data directly to any kind of devices or forward them by e-mail: the optimum measurement data management system generates suitable telegrams for you as well as automatically dispatched e-mails with current sensor data, e.g. for online quality checks.

Integrated interfaces offer ample possibilities to get the best out of your data. The web-based GUI makes it easy to configure and save an export of data. Or you compress your data in an archive package for transfer to an external storage medium. There also are many other interfaces, such as TCP/IP, Modbus or UDP, that give you ample scope for your own requirements.

Your optimum measurement data management system also makes sure your data are at all times kept in a safe place. For this purpose, they are continuously stored in a central database. If you want to preclude data losses and ensure fail safety, you should mirror the data to a backup server. The backup runs your system reliably enough that no administrative intervention is required at runtime.

Dashboards just the way you want them

Presumably, you will have your own, special demands on how parameters are visualized. Your professional measurement data management system should therefore provide a flexible display framework to present any of the parameters available in the system online. You can define the display just as you need it. Or you can use pre-defined displays, e.g. for navigation, winch or weather data.


Archiving across mission limits

Looking at single expeditions, several journeys of individual research vehicles or a single research station doesn't suffice to retrieve the hidden data treasure. That is why the data should safely be transferred to a comprehensive long-term archive where they are correlated in terms of space and time. There, scientists can clearly identify all the data they are interested in and download them for analysis purposes.

A long-term archive will develop its full potential when it collects the data of different research projects and missions, enables data analyses across various missions and provides standardized interfaces for data access even by external analysis and evaluation tools. Then, the archive can be the starting point for the analysis and evaluation of maritime measurement data and provide the database for new discoveries. They are the fuel that nurtures the development of new ideas and creates the basis for vital decisions on our future.
