2013 mooring campaign - success!

Some days ago the last of the 4 Svalbard year-round moorings, deployed in Rijpfjorden, was successfully retrieved during a UNIS cruise. All instruments were happy, and even the blue mussles, deployed in a small cage, were still alive. So, good news for the entire mooring campaign. All moorings are serviced and set out again for another year of data aquisition. You can find a detailed setup under the Mooring setup link.


Kongsfjorden #1:

Purpose: 12 month standard observatory

Instrumentation: Exactly the same as 2012-13 12 month deployment (2x ADCP + 2x Sed Trap)

Set-up: Same as 2012-13 12 month deployment

Deployment: AB321 Sept/Oct 2013

Recovery: AB202 2014


Rijpfjorden #1:

Purpose: 12 month standard observatory

Instrumentation:  Same as the 2012-13 12 month deployment (2x ADCP but only one sediment trap probably at 100m?)

Set-up: Same as 2012-13 12 month deployment

Deployment: AB321 Sept/Oct 2013

Recovery: AB202 2014 (perhaps?)


Billefjorden #1:

No deployment this year


Isfjorden #1:

Purpose: 1 month deployment to support lunar experiment with period of NEW and FULL moon

Instrumentation: 2x ADCP if possible covering surface to as deep as possible; 1 x Sedtrap (probably at 40-50 m?), T&S as available

Set-up: ADCPs to ping asynchronously with set up similar to 36 hour deployments to start 1 Dec and end 31 Dec.  Ping rate such that battery is exhausted.  Sed trap bottle timing being decided by Kim.  Will pass this ASAP.

Deployment: AB321 Sept/Oct 2013

Recovery: Helmer Hansen in January.


Kongsfjorden #2:

Purpose: 4 day deployment to support CIRCA sampling in January 2014 – this will be the Isfjorden #1 mooring turned around.

Instrumentation: 2x ADCP covering surface to as deep as possible; 1 x Sedtrap (probably at 40-50 m?), T&S as available

Set-up: ADCPs to ping asynchronously with set up similar to 36 hour deployments to reveal any complex patterns.  Ping rate as fast as possible.  Sed trap preset in Tromsø by CRG after AB321 with bottle timings to be decided by JB/KL/FC/CG.

Deployment: Helmer Hansen at start of CIRCA

Recovery: Helmer Hansen before departure from KF and redeployed as Kongsfjorden #3


Kongsfjorden #3:

Purpose: 3 month deployment to provide high resolution spring data set spanning 24 hr dark to 24 hr light – this will be the Kongsfjorden #2 mooring turned around.

Instrumentation: 2x ADCP covering surface to as deep as possible; 1 x Sedtrap (Isfjorden #1 Sedtrap reloaded and reprogrammed), T&S as available

Set-up: ADCPs to ping asynchronously with ping rate as high as possible and battery exhausted by 30 April 2014 to reveal complex patterns.  Sed trap set up on Helmer Hansen during Jan 2014 with bottle timings to be decided by JB/KL/FC

Deployment: Helmer Hansen before departure from KF in January

Recovery: AB202 in Aug/Sept 2014

Kongsfjorden and Rijpfjorden Observatory Programme (KROP)

The collection of background oceanographic data over a longer time is of great importance. Time series stations in the fjords allow us to track the changes in the environment and the separate unique events from permanent changes.

Under the lead of Jørgen Berge (UiT/UNIS) and Finlo Cottier (SAMS), we are maintaining two long-term observatories. One is located in Rijpjorden (established in 2006 by UNIS & SAMS), the other one in Kongsfjorden (established 2002 by SAMS). The observatories consist of a set of standard instruments which are deployed every year (CTDs, ADCPs, sediment traps), as well as “guest instrumentation”, which we add upon request by collaborating researchers (e. g. AURAL hydrophones (NPI), RAS autonomous water samplers (FAABulous/AWI/APN), settlement plates (APN) and more).  For the instrumentation setup please refer to the mooring diagrams.

All collected data will be made freely available online soon. We are currently working with the IT department at UiT to change the format all historic data to NetCDF and will publish it continuously. Using the NetCDF format will allow for users to create and download their own datasets online, using only the variables they are interested in. In the meantime, please contact Jørgen Berge if you wish to access and use data from the observatories.

The observatories are registered in the Research in Svalbard database.

Kongsfjorden: RIS 11107

Rijpfjorden: RIS 11106
