All major businesses that have a discharge point into water and according to the Environmental Code are classified as environmentally hazardous are also responsible for taking samples of the water they discharge themselves. Such a business can, for example, be an industry, a sewage treatment plant or a large farm. Since the water that a discharge point empties into is called a recipient, this sampling is called recipient control. The municipality conducts water quality sampling at all discharge points from the treatment plants. Through this sampling, we measure, among other things, depth of view, oxygen content, levels of nutrients and more. The purpose of the investigation is to describe and monitor the environmental impact on the recipient from Osthamar's treatment plant and urban area.

GEMS Survey Ltd. (GEMS) were contracted by Forewind Limited to undertake a bathymetric and geophysical survey of the Tranche A development area and two met mast locations (which were later revised) within the Dogger Bank Zone, in addition to a cable reconnaissance from Tranche A to the Yorkshire coastline. This survey was carried out between 8 July 2010 and 26 December 2010. The primary objectives of the survey were to produce sufficiently high resolution bathymetric and geophysical data and interpretations to allow regional interpretation for planning and modelling purposes; for met mast design to commence and to provide high quality data to inform further benthic and environmental surveys. GEMS supplied interpreted datasets compatible with ESRI ArcGIS software. The GIS data included bathymetry, sidescan sonar mosaics, seabed features, sediments and obstructions.

The methodology used for monitoring has been applied in the Baltic Sea Region since 2011 and is based on the recommendations issued by UNEP/IOC in 2009. It has been further developed, considering the guidelines of HELCOM, OSPAR, and recommendations of the European Commission's JRC Marine Litter working group. Marine beach litter monitoring data were gathered from 15 beaches. Monitoring of 13 sites was conducted three times during the spring, summer, and autumn periods, while two beaches were visited once (in the spring) and then replaced with other beaches (no further marine litter monitoring was carried out at these sites in 2023).

The investigations of Blekinge coast started in 1978. In 1990 the program "Blekinge Kustvattenkontrollprogram." water control program, was formed, building on the stations sampled earlier, but with extended sampling.

Since 2015, 12 representative sites of the Mahoran reefs have been equipped on the sub-surface with probes measuring the temperature every 10 minutes (every 1 hour since mid-2021). The data from these probes are collected every 2 months by the Operations Department of the Parc marin de Mayotte. The aim is to better understand seasonal variations and bleaching phenomena. A computer program developed by the PNMM makes it possible to analyse these data. Regularly, new probes are purchased (NKE) and calibration tests are carried out.
