Draft guidelines for determination of salinity and temperature using CTD (2MA-5)

• Draft for determination of salinity previously presented to the meeting
• Use of CTD included in new version
• Determination of temperature included in new version, as suggested by S&C
• Workshop on use of CTD use in monitoring in the Baltic Sea (initiated by IOW,

Germany) provided valuable input

Draft guidelines for determination of dissolved oxygen

• DELAYED!
• Recommendations for use of optodes/oxygen sensors for CTD still missing

(choice of sensors, maintenance, calibration)

• Upcoming workshop on use of CTD use in monitoring in the Baltic Sea (initiated

by IOW, Germany) will likely provide material guidelines

Draft guidelines for physical

• ceanography
• STILL NOT COMPLETE!
• Material difficult to fit into template
• Should probably be split into multiple guideline documents
• Previous S & C meeting recommended focus on techniques/applications

currently used in monitoring
