Summary of Field Work: |
Characterization of virus-host interactions and link to
environmental scale processes from molecular data
We will collect water column samples across a 96-hour high resolution
(every 4 hours) time course to isolate nucleic acids for characterization. In
parallel we will complete on-deck experiments to estimate virus production
rate, bacterial production and primary production rates. Real time
measurements of pigments and nutrients will be made in the laboratory.

|
Summary of Facility Requirements: |
We will need a CTD/Rosette system for sampling multiple depths up to 500 m. We will require ADCP as well as access to ships meteorological logs. We will require sufficient deck space to set up flow through deck incubators (and access to a surface water supply to feed these). We will require wet lab space for filtration as well as sample processing (nutrients and chlorophylls) |

Optimum Start Date:
|
4/1/2022 |
Dates to Avoid: |
Our goal is to capture the spring bloom (and late summer
stratified or early fall communities with our 2019 effort) as they will be different.
This request is taking into account time lost in 2020 due to the COVID outbreak and projections for vaccine and treatment development to allow for the necessary complement of researchers to be on board. We have discussed this with program management at NSF. |

Description of Repeating cruise requirements: |
We have previously requested and completed a fall 2019 cruise. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The Atlantic explorer is the closest UNOLS ship to BATS. It also has the capabilities required for our efforts. |

 Important Info on Foreign Research Clearances
|
|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |
| Questions about ITAR/EAR regulations?
|
Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
The revised plan is to engage the ship on the east coast of the United States (where it will be in drydock) and sail with it directly to the field location (near BATS). We will then disembark in Bermuda after the cruise. |

|
Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
St. George's, Bermuda |
None |
St. George's, Bermuda |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
The ship will be in service at a US port (to be determined, so we just left it as St George's). We will engage the ship on the eastern US seaboard and ride along to BATS, complete our study then disembark. |

Explanation of Science Party Requirements and Technician Requirements |
We will need assistance deploying the CTD/Rosette
system. As work will be ongoing through the night we assume we will need at
least 2 technicians. This will need to be discussed with the ship. Science
party estimate is minimum staffing.
We would also like to deploy a drogue/float to allow us to follow a single patch of water as we did in Oct 2019. |
