Summary of Field Work: |
We propose a 30-day cruise in the summer 2016. The primary focus will be to characterize seawater and primary marine aerosol that are generated with a high-capacity marine aerosol generator at four stations, two oligotrophic stations in the Sargasso Sea and two biologically productive stations, one in the Mid Atlantic Bight and the other on George’s Bank. We will occupy the two oligotrophic stations for ~8 days each and the two biologically productive stations for ~5 days each. Briefly, the sampling strategy at each station will include determination of the physical and chemical characteristics of primary marine aerosol that are generated with the marine aerosol generator from surface and deep seawater. We will also we expose aerosol extracts to sunlight in deckboard incubations to examine the optical properties and photochemical reactivity of the organic matter associated with the aerosol. CTD casts will be deployed at each station to characterize the physical and chemical properties of seawater as a function of depth in the water column. Depth-dependent seawater properties that will be quantified include dissolved organic carbon (DOC) and Chl a concentration, bubble surface tension, salinity, and temperature. At the two oligotrophic stations in the Sargasso Sea, North Atlantic Deep Water from a depth of 2000 m will be sampled with Niskin bottles, subsampled for chemical characterization, and pumped through the aerosol generator to generate and characterize the physical and chemical properties of the aerosols that are generated. We will also conduct diurnal studies to examine day-night effects on the production of marine aerosols. |

Summary of Facility Requirements: |
We will need space on the fantail for a van that will house a large (approx. 3 m high) sea salt generator. CTD with a 24 bottle rosette (if possible) containing 12 L (or larger) Niskin bottles. Clean flow-through seawater system. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We will use a 8'x8'x20' lab van to generate marine particles. The van will be shipped to the Endeavor prior to the cruise. We plan to have the van secured to the main deck in the fantail. The van will need to be supplied with clean power and clean, non-contaminated seawater.

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
We need a temperature controlled van to hold 20 to 30 20 Liter carboys at a time for each of our four deep water experiments at the Sargasso Sea stations--one at BATS and the second at a site due west of BATS. |
