Summary of Field Work: |
We are proposing to work in the Chukchi Sea (Western Arctic) comparing under-ice and open-water phytoplankton blooms. The work will consist of mooring deployments on the Chukchi shelf in the summer of 2013 (aboard an already funded cruise of Dr. R. Pickart's, WHOI) and one 70 day cruise (2 legs of 35 days each) during the spring/summer 2014. The first leg will start April 25, 2014 and the second leg will begin approximately June 2nd 2014. We will spend much of the time in the ice and will require the use of the US Coast Guard Ice Breaker Healy. We will conduct standard oceanographic water column profiles both in open water and in the ice, as well as ice stations and drift experiments while the ship is within ice. For both the ice stations and the drift experiments within the ice we will need access to the ice for on-ice measurements. |
|
Summary of Facility Requirements: |
We will require the ship's standard CTD/ADCP/Rosette and niskin bottle (12 x 30L) package. Full use of the lab spaces will be made, including the temperature controlled rooms. We will need -80°C, -20°C freezer space. Additionally we will need a radioisotope container on deck for 14C primary productivity work. We will also conduct on-deck incubations. Lastly we will use the underway seawater system for multiple instruments. We will need access to the suite of the Healy's underway atmospheric and oceanographic data. |

Optimum Start Date:
|
4/25/2014 |
Dates to Avoid: |
Our work is dependent on both ice and light being present in the Chukchi Sea at the same time. We need to catch the full evolution of ice melting and phytoplankton growth blooming. We therefore have a strict start requirement as the timing of these events is not too variable between years. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We require the USCG Healy because the work will be in the iced over Chukchi Sea.

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
This request is for a 70 day cruise split into 2 x 35 day legs. We request a crew change at 35 days and suggest this be done by helicopter in Barrow, Alaska if possible. We recognize this may not be possible and are amenable to either Nome or Dutch Harbor, Alaska if Barrow can not be accommodated. We have previously started and ended cruises in Dutch Harbor and Seward, AK respectively. |

Explanation of Science Party Requirements and Technician Requirements |
We will bring approximately 20 scientists to the ship. We request the services of 4 marine science techs, 1 electrical/computer tech (e.g. Steve Roberts), and a tech that fills the role Scott Hiller normally fills (general super tech for the Healy) |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We will perform 14C primary productivity experiments aboard the cruise. The work will take place in a Rad Lab which is on deck. Additionally, bottles with 14C will be incubated on deck in incubators.
We also have need for the ship's 2 ADCPs.
