Summary of Field Work: |
We will take 8-10nundergraduate students aboard the R/V Oceanus for an intensive ship-based research experience to sample and study the biodiversity of oxygen minimum zone inhabitants off the coast of Oregon. Students will be active participants in all shipboard activities, which will include several sampling methods designed to collect diverse organisms in good condition and to study the distribution of organisms in relation to the physical and chemical environment. The PI and collaborators have extensive experience with these methods.
I. Trawling: We will use a 3 m2 Tucker Trawl equipped with a 30-liter insulated cod-end. The net was designed to capture delicate organisms in good condition without subjecting them to temperatures outside their normal range. The net is equipped with a temperature and depth probe and utilizes a MOCNESS opening-closing mechanism. It requires an optical or 0.68 conducting cable. This net belongs to collaborator Seibel and has been used successfully aboard the R/V Oceanus previously. We will conduct day and night trawls at 50 and 400 m depths to observe diel vertical migration in oxygenated water and a systematic series of deeper tows (600-1200) to assess biodiversity and study how it changes in relation to changing oxygen concentrations in addition to other physical factors (sunlight, food availability, etc.).
II. Jigging: We will “jig” over the side of the ship at night to collect nektonic squids.
III. CTD Profiles: We will conduct daily CTDO (conductivity, temperature, depth and oxygen) casts to 1200 m depth. Water samples will be collected from Go-Flow bottles and processed for Chlorophyll, oxygen concentration and carbonate chemistry (pH and alkalinity).
IV. Additional shipboard measurements and sample processing: We will measure organismal water content, take morphometrics, examine stomach contents, observe behavior, photograph and preserve all specimens.
V. Processing of collected material: Students will participate in the collection of copepods, cephalopods and fishes that will be used by the PI and collaborators for future scientific research. Students will be active participants of onboard collection and processing: tissue will be taken from all specimens, with subsamples preserved in RNAlater and 100% ethanol. All voucher specimens will be preserved and stored at the PSU Museum of Natural History.
The cruise will ideally be scheduled to accommodate student academic terms, ideally between June and August 2018. |
|
Summary of Facility Requirements: |
We will provide the net needed to conduct midwater trawls, but will need a CTD/rosette, wire for towing, and sufficient deck space/A-frame for mooring deployments. Feasibility of using our own midwater net has already been discussed with the Marine Superintendant (Stewart Lamerdin) for the R/V Oceanus. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
I applied for and received funding from Oregon State University to take a group of undergraduates to sample the Oxygen Minimum Zone off the coast of Oregon. Scheduling the trip close to the end of our Spring term (e.g. June 18th) would be ideal as the students will have spent the spring term preparing for the expedition. |
