Description

The sediments layer protraits the type of sea floor you can find in the Baltic Sea area.

MSP Challenge

The sediments layer is a static layer, it can help in decision making to plan for wind-farms or other structures fixed to the sea-floor. It can also assist in identifying potentially important areas for protection.

Original Title

Seabed sediment polygon (BALANCE)

Description

"The dataset was created to be used in the HELCOM Baltic Sea Impact Index (BSII). It represents benthic biotope complexes in the Baltic Sea, based on a combination of geological sediment data and light availability data. The dataset contains the following six classes: 1 = Photic sand 2 = Non-photic sand 3 = Photic mud and clay 4 = Non-photic mud and clay 5 = Photic hard bottom 6 = Non-photic hard bottom The sediment data used in this dataset has been produced within the EU Interreg IIIB project BALANCE (www.balance-eu.org). The light availability data has been produced withing the EUSeaMap project (unpublished data) and was reported on request to HELCOM Secreteriat by DHI."

Methodology

This layer was adapted for MSP Challenge integration. The photic and non-photic zones were merged to obtain just the sediments' classes: sand, mud and clay , and hard bottom.
