Summary of Field Work: |
In 2012 we request a 30 day cruise with a suggested start and end port of San Diego. The purpose of the cruise will be to study the low oxygen water column in the Eastern tropical North Pacific. Basically we will work between 24 degrees North to 13 degrees North and between 95 degrees West and 112 degrees West. We anticipate a cruise track that will cover about 4000 nautical miles. Along this track we will occupy about 50 CTD where we will collect water samples for dissolved oxygen and nutrient analysis We will make select about 20 of these for rate measurements rate measurements using stable isotope tracers. (Rate measurement sites will be chosen based on hydrography and water-column oxygen content.) We will also pick two sites for extensive experimental work. These sites will be occupied for several days. Here we will do multiple CTD’s to collect water for incubation-amendment experiments and deploy floating sediment traps several times to collect sinking particulate material. We anticipate there will be ancillary (invited) scientists that will make other measurements. This cruise will be coordinated with an undergraduate class at the University of Washington and the timing around the University of Washington Spring break is critical. Because of this coordination the University of Washington will contribute 12 days of Ship-time funding.
In 2013 we request a 30 day cruise with a suggested start and end port of Arica, Chile. The purpose of the cruise will be to study the low oxygen water column in the Eastern tropical North Pacific. Basically we will work between 10 degrees North to 25 degrees South and between 75 degrees West and 85 degrees West. We anticipate a cruise track that will cover about 4000 nautical miles. Along this track we will occupy about 50 CTD where we will collect water samples for dissolved oxygen and nutrient analysis We will make select about 20 of these for rate measurements rate measurements using stable isotope tracers. (Rate measurement sites will be chosen based on hydrography and water-column oxygen content.) We will also pick two sites for extensive experimental work. These sites will be occupied for several days. Here we will do multiple CTD's to collect water for incubation-amendment experiments and deploy floating sediment traps several times to collect sinking particulate material.

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The UW senior thesis class will be incorporated into this cruise and the UW will contribute ship time. Consequently this cruise needs to include the time period of the spring break at UW in 2012 |
