Summary of Field Work: |
The proposed fieldwork (summer 2013) is to join the UNOLS cruise for the new NSF funded project award to Dr. Dennis Hansell, University of Miami. It would be a survey-type expedition of the N. Pacific to compare photochemical reactivity for surface and deep DOC pools. The project requires collecting water samples from the abyssal N. Pacific to examine the most refractory DOC available for comparison to surface and mid-depth samples. Deep CTD / Rosette casts would provide water and oceanographic context for comparison to surface samples. We will analyze profiles for EEMS fluorescence and CDOM absorbance onboard. We will perform shipboard laboratory irradiations and analysis of photochemical production of CO, HOOH, and other indicators of photochemical reactivity (FDOM & CDOM fading) for fresh samples at sea. Some samples will be stored for shipment back to home labs for further analysis. The current proposal is to leave from Dutch Harbor, AK, south to 47N which will be followed east to 152W, northeast to Papa at 50N 145W, continuing NE to the Gulf of Alaska then disembark at Sitka, AK. |
|
Summary of Facility Requirements: |
Lab: Inside laboratory space for photochemical irradiations with a solar simulator (240V) and analysis by spectrophotometry, spectrofluorometry, chemiluminesce, and gas chromatography. High quality water supply, and refrigerated storage space for samples waiting to analyze and to ship home at the end of the cruise. No clean room, radioactive area, or other specialized space is currently anticipated.
Deck: 5K profiling capability for CTD and Rosette water collection (24 bottles from which a max of 2L/ea is required for our sampling). In situ oceanographic profile data (T, S, O2, CDOM & Chlor-fluorescence, etc.). |
|
Summary of other requirements and comments: |
This proposed UNOLS ship use is to join the new NSF funded research award to Dennis Hansell (UMiami). Our work would be done in concert with his oceanic DOC survey over the same time and space. While our very best option would be to coordinate with Dr. Hansell, and others that are working on related problems, we could make good use of any shiptime that allowed sampling of the deep Pacific DOC pool on an extended east-west transect. |
