Science Summary:
Responding to urgent needs for a long-term multidisciplinary observation system for understanding rapid high-latitude climate change in the Arctic Ocean, a Eurasian and Makarov Basin (EMB) observational network will be created as an element of the Arctic Observing Network (AON). Three August-September cruises, one every two years, will be conducted, with extensive measurements along continental margins, a boundary current conduit; cruises will cover vast areas from Svalbard to the East Siberian Sea. The program ties together oceanographic, chemical, and ice observations using moorings, repeated oceanographic sections, and Lagrangian drifters to provide vital information about Arctic Ocean changes. The overarching goal of the study as an AON element is to compile a cohesive picture of the state and transformations of Atlantic Water (AW) in the EMB, with particular focus on three major observational targets: (1) along-slope AW transport by the boundary currents; (2) interaction of AW branches with shelf waters, deep basin interior and upper ocean; and (3) EMB indications of changes in the upper ocean circulation. The proposed targets are broad in scope and pose a wide range of challenges to modern high-latitude observational oceanography. The EMB's size and location mean that this part of the Arctic Ocean is representative of pan-arctic conditions and processes, and therefore appropriate for long-term observing. Therefore, the project is an important element of the AON. Graduate students will be supported; female and Alaska Native students will be encouraged to participate. Program outreach will culminate in 2013 with a shipboard summer school. Data and products, critically-needed benchmarks for Arctic satellite sea-ice and altimeter measurements, will be available per AON data policy.

Logistics Summary:
This collaboration between Polyakov (1203473, UAF) and Alkire (1203146, APL) aims to compile a cohesive picture of the climatic changes in the Eurasian and Makarov basins (EMB) of the Arctic Ocean, with particular focus on understanding three major observational targets: Along-slope AW transport by the boundary currents, Interaction of AW branches with shelf waters, deep basin interior and upper ocean, and EMB indications of changes in the upper ocean circulation. This project will also continue vital boundary current observations that have been maintained since 2002 as a part of the Nansen and Amundsen Basins Observational System (NABOS) program. Observations will be coordinated with other AON elements like the North Pole Environmental Observatory (NPEO), the International Arctic Buoy Program (IABP), and the international Ice-Tethered Profiler (ITP) Program. In 2013 and 2015 a research team of 8 will conduct three August-September cruises, with repeated oceanographic sections and deployment of moorings and Lagrangian drifters. One ~45 day summer school for graduate students will be held in 2013 aboard the icebreaker. In 2013, NSF supplement 1338948, will provide additional funds for researchers to join the NABOS cruise on board the AARI RV "Akademik Fedorov". This international, multidisciplinary effort will explore the Arctic Ocean’s Eurasian and Makarov Basins. Three August-September cruises, one every two years, are planned, with extensive measurements along continental margins, a boundary current conduit; cruises will cover vast areas from Svalbard to the East Siberian Sea. The program ties together oceanographic, chemical, and ice observations using moorings, repeated oceanographic sections, and Lagrangian drifters to provide vital information about Arctic Ocean changes. Researchers will originate from Kirkenes, Norway or St Petersburg, Russia. There will be approximately 33 days of research cruise time with 8 days in transit. Ship-based sampling will include conductivity-temperature-depth (CTD)/rosette and geochemistry sampling and attendant sea-ice and atmospheric observations. Researchers anticipate two-year-long mooring deployments. A total number of six moorings will be deployed in 2013 and for 2015 researchers plan to deploy three moorings at the A cross-slope section. Several meteorological buoys (IABPs from I. Rigor) and one ice-mass buoy (IMB) from the Cold Regions Research and Engineering Laboratory (D. Perovich) will be available for deployment during each cruise. A workshop for over 20 students will be held in Fairbanks, AK as well in 2015 and 2016. Researchers will return to Russia in 2015. In 2017 NSF supplement 1740757 was awarded to support one more year of vessel research. Researchers would continue standard CTD casts, as well as continue to recover existing moorings and deploying new ones The original cruise was scheduled for 2017, but was postponed to 2018.

CPS will provide a satellite phone in 2015. All logistics will be organized by the researchers and paid through the grant.
