Other samples will be made available through a sample archive and request system available
through the website http://cmore.soest.hawaii.edu/
9.3 Proposed means to provide coastal state with assessment of data, samples and research
results or provide assistance in their assessment or interpretation:
The Center for Microbial Research and Education holds an annual meeting in Honolulu each
spring summer. Chilean collaborators will be invited to participate at this meeting and at any
special sessions held at national and international scientific meetings.
9.4 Proposed means of making results internationally available:
Results will be made available through publication in peer reviewed journals, data deposited in
data archives, and through the website http://cmore.soest.hawaii.edu/
For the underway data collection: The R2R Portal is a central shore-side data gateway through
which underway data from oceanographic expeditions will be routinely cataloged and securely
transmitted to the national long-term digital data archives including the National Geophysical Data
Center (NGDC) and National Oceanographic Data Center (NODC). Data submission will be
established through ship operators rather than individual science parties, ensuring routine
preservation of the full underway data distribution from each ocean expedition.

2010 South Pacific Subtropical Gyre Cruise
Our expedition is designed to investigate the impact of elemental nutrient (nitrogen, phosphorus, iron, silicon, carbon)
ratios on marine productivity and microbial community composition. The South Pacific Subtropical Gyre (SPSG) is
characterized by very high nutrient concentrations in the waters adjacent to the Chilean coast, but very low nutrient
concentrations in the mid-gyre, near Easter Island. The steep gradient in nutrient concentrations across the region affects the
level of marine production, the composition of the microbial community, and the operation of major biogeochemical cycles
in ways that are not fully understand. Previous expeditions to the region have measured the nutrient field, but there have
been few simultaneous measurements of chemical properties with microbial community structure and function.
We propose to sample along a line extending from the Chilean coast near Iquique to Easter Island (Fig. 1). We will occupy
three major “process” stations for up to five days each; a high productivity, near shore station (in the area of 20oS 70o 30’W;
Fig. 2), a mid-cruise station in the nutrient transition zone (in the area of 23 o 30’S, 89o30’W), and a low productivity, midgyre station near Easter Island (in the area of 27 oS, 108o 30’W). In between these stations, we will briefly sample at eight
additional “survey” stations at lower intensity along the cruise track (Table 1, Fig. 1).
At each process station we will deploy and recover an underwater autonomous vehicle to make synoptic measurements of
optical, physical and chemical properties of the water column near the sampling station. We will deploy and recover free
drifting particle interceptor or sediment traps to measure the vertical flux of particulate matter, free drifting samplers to
measure marine productivity and important microbial processes (nitrogen cycling, carbon and oxygen consumption, nutrient
uptake). We will also deploy and recover plankton nets and pumping systems to collect particulate matter for chemical and
microbial analyses and make extensive use of rosette mounted water bottle samplers to measure water column dissolved and
particulate nutrient concentrations, as well as optical, physical, and chemical properties of the water column. We will also
collect samples for microbial analysis.
We plan to conduct shipboard incubation experiments to study the effect of changing elemental nutrient ratios on microbial
productivity and community structure. Water samples will be amended with nutrients in specific amounts and the changes
in chemical and microbial properties will be monitored over time while the samples are maintained in constant temperature
incubators located onboard the ship.
We will make a smaller set of measurements at the eight “survey” stations. These will occur approximately twice each day
east of 23o30’W and once a day west of 23o30’W. At survey stations we plan to make two or three short deployments of our
rosette-mounted water bottle samples to profile the water column for chemical and microbial properties as mentioned above.
Finally, we will collect some underway samples on the return trip to Valpariso, Chile.
