Summary of Field Work: |
This project will continuously measure and sample surface ocean waters for dissolved CH4, nutrients, dissolved oxygen, and chlorophyll as well as the atmosphere for CH4. These measurements will be made underway as we transit from Lewes, DE to the Gulfport, MS.
In addition, we will collect water column samples for natural isotopes of methane (14C-CH4 and d13C-CH4) at locations along this transect. This involves large volume sampling to be supplied by the PI. Before or after this sampling operation, we will also conduct a CTD at each station. |
|
Summary of Facility Requirements: |
1) CTD with 10 L niskin bottles.
2) Separate winch wire to attach 3-inch diameter suction hose for large volume sampling.
3) Wet lab and dry lab. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
This project will measure and sample waters in the U.S. north-Pacific margin. This vessel is the appropriate size and in the appropriate location for this work. We have another cruise from June 11-29, 2019 sailing from Astoria, Oregon and thus are unavailable on these dates. |

Explanation of Science Party Requirements and Technician Requirements |
This cruise will be collecting continuous surface water data and samples. The PI will provide a system to measure the dissolved methane concentration in seawater and a continuous surface water pump.
While this operation is continuous while underway, we will also periodically collect water column samples for natural methane isotopes. These samples are collected by pumping large volumes of water up from specific depths. The PI will supply their own pump and suction hose, and will work with the ship's captain and tech to make sure this operation is conducted safely and effectively.
While both operations have been developed in the PIs lab, they have been used successfully on cruises in the Artic, Great Lakes, and U.S. Atlantic Margin. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Most sampling and analysis equipment will be supplied by the PI. However, we will need to mount a pump over the side of the ship throughout this cruise. We will also have to periodically attach 3-inch diameter suction hose to a winch wire and lower to specific depths to collect large volume samples.
