Arctic and Antarctic Research Institute (AARI), Russia Purchased a WHOI Ice Tethered Profiler (ITP, ocean buoy), which was deployed from the Federov along with other DAMOCLES buoys last summer. Provide buoy deployment logistics from Russian Ice Breakers, i.e. the Kapitan Dranitsyn for the NABOS cruise, and the Federov for DAMOCLES. Deployed North Pole Drift Station 35 at 81.5N 104E in September. SVP buoys are planned to be deployed from the Kapitan Dranitsyn this summer during the NABOS cruise in international waters. Plan to deploy NP-36.

Chinese Arctic and Antarctic Administration (CAAA)  Sun Bo of the Polar Research Institute of China (PRIC), and Jiping Liu, who is at Georgia Institute of Technology report that they are planning to deploy two or three ice mass balance buoys this summer in the Arctic during the cruise of the Xuelong. This ice breaker is also collaborating with DAMOCLES.

Cold Regions Research and Engineering Lab (CRREL), USA Deployed 13 Ice Mass Balance (IMB) buoys in 2007 in collaboration with DAMOCLES, EC, IOS, McGill University, NIC, NOAA/PMEL, and PSC. Many of these buoys were collocated with ocean buoys to for ADS. Plans for 2008 (provided by B. Elder): –NPEO: 1 IMB deployed ARGOS ID Early April –DAMOCLES I will be deploying 3 IMBs with Damocles Starting around 7 April 2008 out of Eureka Canada. The plan is to deploy between 83 and 87 N W. 3 CRREL/Metocean IMB's, ARGOS ID 07440, 30045, We will spread these out as far as possible in the box 8 or 9 Metocean Beacons (Burghard Brummer - Germany) I think these might have some added sensors from the standard ice beacons as he mention a 4 inch hole for a wind mast. 8 or so Acoustic Ice Tethered Profilers (Jean Claude Gascard- France). –WHOI – Beaufort Gyre cruise: Right now we are planning on 1 IMB to be deployed in August ARGOS ID –Don Perovich and Hajo Eicken have 2 IMB's for SIZONET but I am not positive where they are being deployed. –ARGOS ID and are in production at Metocean, I think one may be going to Japan??? And one may be deployed through Christain Haas. Green-ice program North of Greenland.

International Arctic Research Center (IARC), Japan/USA Deployed 3 clusters of GPS buoys in 2007 at the APL Ice Camp, from the Louie St. Laurent, and from the Polarstern. These were collocated with ocean and IMB buoy deployments. Plans to deploy SVP-B buoys during the NABOS cruise.

Nansen Environmental and Remote Sensing Center (NERSC), Norway  Wish to continue being listed as a Participant of the IABP. They have been collaborating with CMR to develop the SITHOS buoy. They also wish to include the Nansen International Environmental and Remote Sensing Center, St. Petersberg as a new Participant.

Norwegian Meteorological Institute (NMI) Currently have 3 ICEXAIR buoys reporting in the IABP array, but did not contribute a buoy for this summer’s White Trident deployment. NMI is one of the lead institutions of DAMOCLES. Have not been able to contact Knut Bjorheim during the past year.

Norwegian Polar Institute (NPI) Currently has 1 ICEXAIR buoys in the IABP array, 2415 (which was deployed in 2004, and currently reports under NIC’s Argos Experiment number). Sebastian Gerland has been named the new IABP Participant from NPI since Terje Loyning has taken a new position.
