Summary of Results

Several activities have been carried out:

 

Biosensor construction: The French team (University of Bordeaux-CNRS) build the electronics for the deployment of two biosensors, one to work with Chalmys islandica and a second one for working with blue mussels Mytilus edulis. The second biosensor is an in-kind contribution from CNRS as this was not part of the original project.

 

First Chlamys islandica and Mytilus edulis collections: First the clams needed for the polar day experiment and biosensor deployment were collected in a cruise around Svalbard (APN-UiT) and deposited in a cage in Ny-Ålesund. Collection of blue mussels was performed by Peter Leopold from UiT, in Isfjorden.

 

Fieldwork; A fieldtrip was planned and carried out to Ny-Ålesund from the 25th of April to May 2nd to install the 2 biosensors comprised of 16 C. islandica and 16 M. edulis, but also to collect organisms for the polar day genetic sequencing experiment. A cage was installed under the old pier in Ny-Ålesund. The system is working successfully.

 

Second Chlamys islandica collection: The collection of a new batch of 300 scallops was carried out thanks to a collaborative effort between the project and the UiT-UNIS Svalbard Autumn cruise. This batch is in Ny-Ålesund and will be employed to perform the winter and spring experiments

 

Gene sequencing:  Efforts are being carried out to identify the genes controlling the molecular clock and light perception in C. islandica and M. edulis. So far, genes have been identified for M. edulis, i.e. the clock genes Clock, Timless and Cryptochrome 1 and genes coding for opsins involved in light perception. For C. islandica, no clock genes have been sequenced until now, but we have already identified several opsins genes.

 

Winter fieldwork: A second and booked, to sample the first part of the second batch of C. islandica at the end of January 2017. All permits have been obtained.

Spring fieldwork: A third fieldtrip has been planned to Ny-Ålesund to sample the last part of the second batch of C. islandica at the end of March 2017. We are awaiting the permits.

For the Management

Our results are providing key information about future trajectories of climate change upon benthic species in the arctic and ecological processes, and will further increase our understanding of the biology of C. islandica and M. edulis, species that can potentially be employed in real-time environmental monitoring.

Budget in accordance to results

Yes. The funds allowed us to perform all activities planned for the first fieldwork. We have applied for a second year of funding to FRAM, as stated on the original proposal

Could results from the project be subject for any commercial utilization
No
Conclusions

The project has been a success so far, achieving all goals stated in the proposal. In addition, the project has been expanded to include a study of the gapping behavior and growth of blue mussels in Ny-Ålesund.
