2. Ph.D Lars Brammer Nejrup a professional diver and marine biologist has joined Biodataonline. See details under the menu ABOUT.
3. 5 autononomous measurement platforms have been deployed in streams in Northern Denmark (see photo below)
4. BioDataOnline has analysed more than 30 years of data for Kolding kommune Denmark and found clear evidence of human induced changes in the water quality, caused by deforestation. -Go to download area for the full report.-

Biodataonline develops & manufactures measuring systems.

These systems are wireless stand alone applications & require GSM coverage at the location to be measured. The user only needs a standard web browser, user name & a password in order to access the data & adjust the setup of the measuring system.

The equipment can be customized in order to meet almost any wishes our clients may have.

Furthermore, in connection to a given biological field of interest, we offer our assistance in the selection of the key parameters to be measured.

Finally we offer to hand over of a full report, thus giving a presentation of the measurements at hand.

Below development history concerns our top model. Simpler systems are also available on request.

For example a data logger, that will occasionally be active & send SMS to service personnel. Such simple systems can be sufficient in cases that require monitoring at single depths with long interval between measurements, or for monitoring a single parameter in order to send an alarm.

Development history of freshwater vertical profile measuring system:

2006: A simple first prototype was developed.

First prototype at it's initial location.

2007: Above system provided a new scope of data, which enabled the freshwater laboratory at Copenhagen University to verify a number of new algorithms, leading to a deeper understanding of the environment. However, during this season it became evident that the process of retrieving the measured data was quit time consuming, thus a number of data loggers had to be retrieved on location & this data had to be co arranged manually before the data analysis could commence.

2008: At the freshwater symposium in Aarhus, biodataonline introduced a new online based vertical profile measuring system. The system is a stand alone system, which is powered by solar cells, and it is accessed by a standard web browser. The user can specify date interval & download a data file, see the physical location of the system on a map (GPS), change measuring depths & interval, receive alarms by SMS if for example the power supply runs low.

System shown below is equipped with a probe from YSI, but can be adapted to make use of almost any probe with a known interface protocol.
