 Monitoring guidelines

​COMBINE Manual

The COMBINE Manual is directed to perform monitoring to quantify impacts of nutrients and hazardous substances in the marine environment and to measure chemical and hydrographic parameters.

The COMBINE Manual is currently under review. Revised guidelines will be incorporated as part of the Monitoring Manual as they become ready and are adopted.

(Data collected under COMBINE can be downloaded from ICES Oceanographic database. Monitoring data can be also visualized and downloaded in the ICES EcoSystemData map service.)


guidelines for coordinated monitoring

Guidelines for Monitoring of Radioactive Substances for discharges and radioactivity in the marine environment. The monitoring quantifies the sources and inputs of artificial radionuclides, as well as the resulting trends in the various compartments of the marine environment (water, biota, sediment).

Guidelines for monitoring ofthe waterborne pollution load quantify emissions of nutrients and hazardous substances to the air, discharges and losses to inland surface waters, and the resulting air and waterborne inputs to the sea.

Manual on Co-operation in Response to Marine Pollution

HELCOM also coordinates the surveillance of deliberate illegal oil spills around the Baltic Sea, and assesses the numbers and distribution of such spills on an annual basis. See Guidelines for Response to spills.
