Summary of Field Work: |
I am the chief for the USGS Pacific Ocean Climate Variability Project, and one of my standing objectives is to study the paleoceanographic evolution of the Pacific Ocean’s role on North American climate. Working with Drs. Joe Carlin (CSU-Fullerton) and Amy Wagner (CSU-Sacramento), we are currently writing an NSF proposal to collect new long marine sediment cores from the California Current Ecosystem (CCE) along a transect between Eureka and San Diego. Together, we hope to develop new Holocene and Pleistocene records of past productivity that reveal the role that Pacific upwelling has played in shaping both the CCE and North American climate.
The selection of the Tanner Basin for this Science Verification Cruise proposal has several advantages:
1. Proximity to San Diego (straight line distance of ~140 nautical miles).
2. Location is the southern end of the CCE upwelling zone.
3. Several long gravity and piston cores have been recovered from Tanner Basin previously (Mortyn et al., 1997; Stott et al., 2000; Herbert et al., 2001), as well as a scientific drill core (Ocean Drilling Program Site 1014). All of these studies indicate sufficient soft sediment thickness to warrant deployment of a piston corer.
4. The most recent piston core from the Tanner Basin was collected in 1995 (EW9504-09PC; 7.19 m core length).
5. There have been many recent advances in paleoceanographic analyses over the last 20 years that require fresh sediment core samples, including core-scanning XRF geochemistry, AMS 14C dating, and 210Pb geochronology.
6. A continuous sediment record is desired that extends from modern day through the Late Pleistocene (e.g., base of recovered piston core). To accomplish this objective, a multi-corer should also be used in conjunction with the piston core/trigger corer system.
If our group is selected to participate, I will conduct a range of biogenic sediment analyses (opal, TOC, organic matter isotopes) and XRF sediment geochemistry, while Drs. Carlin and Wagner will contribute expertise in sedimentology, radionuclide isotope measurements, and AMS 14C geochronology analyses. In addition, the USGS will also archive any retrieved sediment cores in the USGS Western Region Sediment Core Repository for future work by any interested scientist. |
|
Summary of Facility Requirements: |
1. Piston coring system (prefer OSU "jumbo" piston coring system)
2. Multi-corer (for shallow sediment coring)
3. (optional) Gravity corer
4. (optional) Box corer |
|
Summary of other requirements and comments: |
Refrigerated storage for recovered sediment cores while at sea.
I think the following OPTIONAL requests are housed within the OSU equipment pool, but I'm not sure. If the below items can't be used on this SVC cruise, these can be utilized at the USGS afterwards.
OPTIONAL: at-sea core splitter
OPTIONAL: at-sea GEOTEK multi-sensor core logger |

Explanation of Science Party Requirements and Technician Requirements |
Science Party size is dependent on berthing availability for R/V Sally Ride Science Verification Cruise. At a minimum, the science party will consist of myself + 1 USGS technician + OSU sediment coring staff. If berthing is available, my co-PIs Amy Wagner and Joe Carlin (and 1 student per co-PI) would also like to participate. So, the maximum science party size would be 6 + OSU sediment coring personnel. |
