Gerit Birnbaum: Helicopters (Tuesday)
2 BK 117, we will allow for flights during night 700 hours per year are budgeted max. radius: 80 sm Marcel Nicolaus: RV Polarstern (container arrangements) limited space! Hoovercraft ? Dangerous goods: supply for leg 1 is feasable, resupply: we need to know what and how much radio-active material ? Both ways?
3
Drift: • installation of Polarstern in the newly formed sea ice in October 2019 • potential drift is simulated by forward-simulations of sea ice based on satellite derived daily drift vectors from the years – 2013/14 • drift near the North Pole, but within helicopter range from Cape Baranov (Russia) or Longyearbyen (Svalbard) starting position 84° N / 120°E fulfills the plan of transpolar drift

Starting area for the MOSAiC drift: 85oN/120oE
East part of Arctic Basin Sea ice age November 2017 Courtesy of O. Folomeev AARI Starting area for the MOSAiC drift: 85oN/120oE Single year ice available in November 2017
5
Cruise legs Tryoshnikow: start position: personnel, cargo, fuel, set up of remote network Exchange of crew and scientists Leg III – IV: Antonov: 40 pax, runway (Pistenbully), sea ice condition Plan B: helicopter
6
The rotation of the crew and expedition RV “Polarstern”
For the rotation of crew and expedition RV "Polarstern" it is planned to attract icebreaker "Captain Makarov" (December 2019 and February 2020) The plane «Antonov» Ан-74 (40 - single flight) in April or two Mi-8 AMT (route: Khatanga – Cape Chelyuskin-the Cape Baranov - Arctic Cape - RV “Polarstern” and back)

Operational Aspects

Breakout session 4: Operational Aspects
Outline of Russian helicopter operations 2 Helicopters from Khatanga Cape Chelyuskin -> Cape Baranova -> Cape Arctichesky -> Polarstern (300km) 30 pax per helicopter (800 km) Time period/Duration of exchange No overlap time (think of handover procedure) Helicopter Flights from LYB ? need to be discussed with Norwegian authorities
9
Health, safety and environment
Person to be employed: standard procedure manual with rules and regulations ... sea ice break up, ... max. pax on ice, tbd ... polar bear protection, ... proper clothing ... mental health ... Helicopter, RPAs, Aircraft coordination ? Insurance company: HDI: accident and health insurance similar
10
Medical examination: AWI covers costs at AWI doctor Your doctor: minimum: AWI medical form ... Body mass index ...
11
Time schedule: • 2016 – 2019: preparation phase
- final participants lists (January 2019) - briefings (standard op procedures, health and safety, helicopter op …) - early cargo delivery to Tromsø ( departure of PS September 2019 !) • October 2019 – October 2020: drift schedule - drift is split into 6 legs approximately 2 month for each leg Leg 1 somewhat longer (transit to and from the drift floe)
13
Drift – trajectory uncertainties:
• averaged simulated drift track for the starting position 84° N / 120°E • is not a reliable forecast, but helps for an easier planning in particular during summer where sea ice drift detection is uncertain and therefore the drift trajectory as well
14
Legs and Resupply: Leg Date Action Requirements Fuel est. (tons) 1
01 Oct 19 Start of Leg 1 / leave TROMSØ 2400 10 Oct 19 Arrive at Central Observatory floe position in Laptev Sea (e.g. 84°N/ 120°E) and identify suitable ice floe 11 Oct 19 Start to deploy distributed network Russian ship e.g. Academic Federov 14 Oct 19 Refueling (400 tons) at start location Ship takes deployers home 2000>2400 15 Oct 19 Drift starts 18 Oct 19 Time series start 12 Dec 19 Scientist exchange Helicopter via Cape Baranov 2 13 Dec 19 Start of Leg 2 13 Feb 20 Refueling Polarstern (1600 tons) Scientist and crew exchange Russian nuclear icebreaker 555>2155 3 14 Feb 20 Start of Leg 3 09 Apr 20 Helicopter via LYR or Cape Baranov 4 10 Apr 20 Start of Leg 4 11 Jun 20 Refueling Polarstern (1000 tons) International icebreaker e.g. US Vessel or Swedish Oden 385>1385 5 12 Jun 20 Start of Leg 5 13 Aug 20 Snow Dragon possible 440>1440 6 14 Aug 20 Start of Leg 6 18 Oct 20 End of time series 21 Oct 20 End of drift Collect instrumentation from network Steaming to Bremerhaven Evtl. support from other vessel 405 31 Oct 20 Arrival Bremerhaven 55

Personnel and Personnel Exchange:
• 96 persons: 43 crew members 47 scientific participants 4 Helicopter crew (2 pilots, 2 technicians) 2 pax weather forecast (DWD) (1 meteorologist,1 technician) - 47 scientists include: 1 cruise leader 1 chief scientist 2 safety guards 1 data manager 2 media/outreach representatives 40 remaining scientists: Atmosphere: 8 persons Sea ice and snow cover: 8 persons Ocean: 5 persons Bio-geochemistry: 4 persons Ecosystem: 6 persons added to different teams: 9 persons - 10 additional scientist during Leg 4 and Leg 5, will mostly live in the secondary camp - 4 persons: logistical and technical support are needed discuss which needs can be covered by the crew
16
Personnel and Personnel Exchange:
• exchange of scientific personnel after each leg - 8 to 10 people from the different teams stay on board for 2 consecutive legs - exchange during refueling or via Cape Baranov (Russia) with helicopters • ship crew will be changed after every other leg during ship supply
17
Funding of MOSAiC Polarstern: 396 days ~28 Mio EUR (provided by AWI)
Remaining funding needs: 14.4 Mio EUR: Resupply: 10.2 Mio EUR Neumayer supply: 1.5 Mio EUR Person exchange: 1.2 Mio EUR Other logistics and safety: 1.5 Mio EUR => Participants fee: 1400 EUR/day EU/NSF/others: calls and/or tenders Not included Science positions Science equipment
18
Rescue and Alternative Plans:
• drift into the Beaufort Gyre (very unlikely) experiments will be interrupted and shifted towards the transpolar drift • medical emergencies helicopter flights from Cape Baranov or Longyearbyen alternative plans: • Plan B – without a nuclear icebreaker drift track shifted eastwards (between transpolar and NP35 drift) non-nuclear icebreaker can be used • Plan C – without any other required refueling drift track like Norwegian N-ICE campaign 2015 Polarstern will leave ice for refueling to a port or meet a tanker ship at the ice edge interruption of measurements at Central Observatory, but distributed network will stay in place
19
Safety Aspects During the Drift:
on board: • safety aspects: weapons (polar bear safety), dangerous goods, radionuclides, samples and frozen goods, lab safety • ship safety will be trained on board • safety regulations will be followed, introduced and supervised by the ship´s safety officers (2 safety guards who are experienced in Arctic fieldwork will join each leg ) • each group leaving the ship will get dedicated safety briefings on ice: • participants will go through safety workshops prior to the legs: - use of safety equipment and rules to obey - work in Arctic winter/summer conditions - proper clothing, introduction into field equipment - helicopter instructions (scientific missions on Polarstern) - general ice camp procedures - first aid - polar bear awareness and protection
