Summary of Field Work: |
We propose three, ten-day research cruises to the BATS station over the period of approximately two years between July 2021 and January 2023. The first cruise is proposed for July 2021, followed by wintertime cruises in January 2022 and January 2023. For each cruise we expect ~0.5 day transit round trip and ~9 full days on station. We will require four days prior to the cruise for set up and testing, and two days after the cruise to disembark.
The primary focus of the four research cruises will be to examine the seasonal variability in the fraction of refractory dissolved organic carbon (RDOC) in primary marine aerosol (PMA) produced from bursting bubbles that are generated in the marine aerosol generator.
To achieve this goal, when we first arrive on station, we will determine basic aerosol physical properties over a two-hour period. We will then collect up to eight sets of daily PMA samples, near-surface seawater, and sea-surface microlayer samples to test our hypotheses. Each day we will collect a pair of PMA samples over ~24 h of continuous sampling to characterize the physical and chemical properties of the PMA. Once per day, we will deploy the CTD to characterize the chemical and physical properties of the water column. Weather permitting, we will also deploy the zodiac daily to collect near-surface seawater and ~50 µm thick sea-surface microlayer samples to characterize the chemical and physical properties of these samples. Sea-surface microlayer samples will be collected with a glass plate and the underlying, near surface seawater sample will be collected using an all-glass syringe. Finally, CTD casts will be deployed on each cruise to characterize the physical and chemical properties of seawater as a function of depth in the upper 200 m. One or more CTD casts will also be devoted to collect seawater samples throughout the water column (~4500 m) at BATS |
|
Summary of Facility Requirements: |
We will need space on the fantail for a 8'x8'x20' lab van that will house the marine aerosol generator; a CTD with a 12 - 24 bottle rosette of ~12 L Niskin bottles; a clean, flow-through seawater system; and high purity laboratory water. We also require electricity, high purity laboratory water, and seawater to be plumbed to the van that houses the aerosol generator—we will provide the tubing and fittings for the high-purity laboratory water and seawater lines. The lab van is a standard 20 ft long shipping container that was outfitted to house the marine aerosol generator. When the container is loaded onto the ship’s fantail, we’ll need enough room to get the outer container doors opened and tied back prior to securing the vessel to leave port.
We wil need bench space to place a portable, class-100 clean hood (approx. 4 ft long, 3 feet wide, and 3 feet tall) to scrub the intake air used to generate high-purity feed air that is pumped to the aerosol generator—the pump is loud so we’d want a space away from people—the wet lab would be a good location. |

Dates to Avoid: |
We are trying to capture a seasonal cycle in dissolved organic carbon over a two year period. The time frame given for the set of four cruises is planned to capture the most extreme range in organic carbon concentrations and compositions relevant to primary marine aerosol formation, which are typically in July and January. |

Description of Repeating cruise requirements: |
We plan three cruises over two years: July 2021, January 2022, January 2023. Therefore, we need to have cruise timing that is consistent for the seasonal study that is planned. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Proximity to BATS and space on deck for a lab van containing our aerosol generator. |
