Summary of Field Work: |
Characterization of living and fossil benthic foraminifera and sediment properties in different seafloor habitats to generate modern analogs for assessments of environmental changes and paleoenvironmental history based on fossil foraminifera. Cruises will focus on hands-on training and research experience for students.
We propose to collect seafloor sediment samples from 3 areas on 2 short cruises per year. Ideally, one cruise would be in the summer, and the other would be on a weekend during the school year. The weekend trip would visit 3 sites on a transect (maximum depth 380 m), and the summer trip would visit 2 sites (about 1000 m water depth). All sites are in the Southern California Bight off San Diego. |
|
Summary of Facility Requirements: |
Weekend cruises: multicorer, large Van veen grab; CTD with 12 bottle rosette, O2 sensor, transmissometer, fluorometer, PAR sensor, 2 pingers, sample storage refrigerator, freezer, -80 freezer, Secchi disc, 3.5 khtz profiler
Summer cruises: multicorer, large Van veen grab; piston corer, CTD with 12 bottle rosette, O2 sensor, transmissometer, fluorometer, PAR sensor, 2 pingers, sample storage refrigerator, freezer, -80 freezer, Secchi disc, 3.5 khtz profiler; side scan sonar; walk in cold room; A-frame and ship-side winch operation deployments |
|
Summary of other requirements and comments: |
We plan to operate 24 hours/day and it would be preferable to have two res techs on board. On the weekend cruises, we plan to make three 8-hour legs, exchanging students each time (we have done this many times through the years using the Sproul to make these sampling legs to visit the same locations). |

Other Ship(s): |
This cruise is planned as a 48-hour weekend trip, visiting 3 sites near San Diego during 3 legs. Each leg will visit a different set of sites, returning to MarFac to exchange students after each leg. We have done this many times over the years on the Sproul. We propose to do this each year for 3 years. A second summer cruise (separate ship time request) per year is also planned, using a larger ship to sample deeper sites during 1 leg voyages.
Preferred dates include:
9/23-9/24; 9/30-10/1; 10/7-10/8; 10/14-10/15 or 9/16-9/17 |

Description of Repeating cruise requirements: |
This cruise will be requested separately (separate ship time request) each year for 3 years
Note that this first of 3 cruises was not undertaken, and would have instead taken place in 2020. However, the 2020 cruise (originally scheduled as one-day, but now authorized for two days) is postponed until 2121 (and authorized by the NSF Program Manager for IUSE Geopaths). |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We prefer to schedule this earlier in the school year as samples from this cruise will be used in courses, labs and student research projects. |

Short Description of Op Area
for use in schedules: |
USD series site |
| Description of Op Area: |
The 3 sites are located roughly due west of Point Loma. Target water depths are 300m (farthest west), 200m and 100m. We have visited these sites with the R/V Sproul many times since 2001. |

We plan a voyage with 3 legs so that we can involve as many students as possible during the 24-hour cruise (we have used this method many times over the years). After visiting site one, we would return to MarFac to replace student participants, and then sample site 2, repeating the procedure for site 3. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We require an Ocean Instruments multicorer and Van Veen grab sampler along with a CTD.
Winch and wire will need to accommodate multicoring, grab sampling and CTD deployment to 400m (max target depth is 300m).
