Ship Request

STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to https://mfp.us and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning (mfp.us). Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact mfp@unols.org for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

Project Title: ASGARD: Arctic Shelf Growth, Advection, Respiration and Deposition Rate Experiments Project Status: Submitted
Principal Investigator: Seth Danielson, UAF_CFOS Project Institution: UAF_CFOS
Project ID: 104975 Version #: 2
Date Submitted: 8/7/2015 7:21:00 PM Created By: Seth Danielson

Funding Agencies: OTHER - NONE - Funded
Summary of Field Work: The ASGARD project is a coordinated ensemble of vessel- and mooring-based process studies consisting of physical, chemical, biological and biogeochemical rate measurements that are designed to better constrain carbon and nutrient dynamics of the northern Bering and Chukchi sea continental shelves. Our fundamental science question is: What regulates variations in carbon transfer pathways and how will the changing ice environment alter these pathways and ecosystem structure in the Pacific Arctic and beyond? Our approach is to measure a broad suite of environmental parameters, with emphasis on biotic and abiotic rates, during the annual shelf transition from ice-covered to ice-free conditions. In particular, we will quantify the physical and chemical environments: the planktonic and benthic microbial and infaunal communities (composition, abundance and biomass); water mass, heat, salt, fresh water, nutrient, and particulate advection rates; phytoplankton growth rates; zooplankton growth, reproduction, feeding and respiration rates; quantity, quality, and degradation rates of sediment organic material; benthic respiration rates; and particle sinking and deposition rates. These analyses will be carried out at poorly-sampled locations and times of year. Year-round biophysical and biogeochemical moored instruments will provide time series context of select parameters at sites located along the primary advective pathways and within multiple water masses and biogeographical regimes.
Summary of Facility Requirements: The R/V Sikuliaq is the required platform for the proposed experiments because it:
• is capable of working in and near the ice edge
• is less expensive to operate than the USCGC Healy and can operate in shallower water depths
• can accommodate a science party of 26-30 berths (including marine technicians)
• has a weather window of operations that is broader than most other vessels, resulting in less science time lost to poor weather (can handle icing conditions; has hands-off over-the-side gear handling systems) , especially when working in and near the ice edge
• has sufficient dry lab, wet lab, cold room, and analytical lab space for all proposed activities
• can accommodate all of Hopcroft’s large deck and lab incubation chambers
• can do coring, bottom grabs, midwater trawls and plumb-staff beam trawls
• has a fully equipped Seabird 9-11 CTD and 24-place rosette with 10-l bottles.
• provides flow-through seawater system with access ports
• provides on-deck running seawater for incubators
• is outfitted with a mast-mounted PAR sensor and associated meteorological instruments
• has a -80 °C freezer
• has a 150 KHz Teledyne RDI Ocean Surveyor ADCP
• can fish mid-water and bottom trawls
• comes with leveraged ship days contributed by UAF.

In addition to the standard ship’s equipment and facilities on board the R/V Sikuliaq, we would request the following special UNOLS equipment:
• A Rad Van for stable isotope productivity experiments.
• A multi-corer for bottom sampling
Summary of other requirements and comments: We propose one 20-day cruise in late May/early June in each of 2017 and 2018 on board the R/V Sikuliaq, NSF’s new polar-class research vessel. An ideal timing would be to leave Nome on May 25 and return to Nome on June 14.

Leveraged Support for Logistics

SFOS will be leveraging state-funded ship days on the R/V Sikuliaq as a resource to support this project. Funds available total $1,200,000 of which $750,000 would be available for the 2017 cruise. Given the current day rate ($43,616, which covers the vessel and technical services, including two marine technicians on board the cruise) and assuming a 5% cost of inflation, $1.2M would cover 25 of the 40 science days needed for the two LTL cruises proposed here. We request that NPRB fund the remaining 15 science days and work with the NSF to ensure the vessel will begin operations in Nome. As the Sikuliaq could be working anywhere in the North Pacific, this could require an extended transit. We will need to schedule this ship time through the NSF-UNOLS ship scheduling system. We are unable to apply these funds to any other vessel.

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
We request the Sikuliaq because we can bring UAF state-funded ship days to this effort totalling $1.2M. Also, we anticipate working near and in the ice edge so an ice-strengthened vessel is required.
