| Project Title / Coordinating Body |
COMBINE - Marine Monitoring in the COMBINE Programme of HELCOM / Helsinki Commission |
| Objectives | |
| Description | The COMBINE 2 cruise contributed to the HELCOM Baltic Sea integrated physical, chemical and biological monitoring programme, focusing especially on long-term macrozoobenthos monitoring and near-bottom water oxygen levels in the open sea area. It also contributed to the long-term monitoring of zooplankton communities and microlitter monitoring. Water and sediment samples were taken for monitoring of radioactive substances (HELCOM MORS programme). In addition a wave buouy was installed in the Bothnian Bay and drifting floats were deployed in the Bothnian Sea and the Northern Baltic Proper. The monitoring activities were part of the Finnish marine management plan. |
