Summary of Field Work: |
We propose to sample water offshore from 4 shore-based stations to better understand the role of upwelled versus regenerated nitrogen to coastal productivity. We will collect water and plankton for stable isotopes of nitrogen, water nutrients, and basic environmental parameters such as salinity, temperature, chlorophyll, dissolved oxygen, and pH. The 4 stations where we will census are those ~ 1 km offshore of Tatoosh Island, Second Beach (Neah Bay), Siip Point (Clallam Bay), Observatory Pt (Freshwater Bay) at depths of ~65 m - 100 m. We will sample from multiple depths up to 100m to understand the relationship between seawater properties at the shore and seawater offshore (1-2km). By comparing on-the-shore and offshore samples, we can estimate a local animal effect on nitrogen dynamics. We anticipate at least 1 full day of ship time at these sites with 2 days of travel time. We propose sampling once in Jun, Jul and Aug, for a total of 9 ship days. |

Summary of Facility Requirements: |
We request the R/V Clifford Barnes, its crew and a CTD technician. On the R/V Barnes, we propose to use the CTD array (both the 6 and 12 bottle units). |

Description of Repeating cruise requirements: |
The same sampling will be done in each month (Jun, Jul, Aug)
We thus request 3 dates of 3 days each:
1. A 3 day window between 21-27 Jun 2011
2. A 3 day window of 10-12 jul or 20-27 Jul 2011
3. A 3 day window between 16-25 Aug 2011 |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The R/V Barnes is requested because we need do not need a large ship, rather one that can work relatively close to shore (1-2 km) and that is based near our project area. We anticipate a modest scientific crew of 4-5.
We propose 3 monthly sampling dates to capture variation in upwelling and local conditions. Although there is flexibility in the 3 days chosen, , we have some constraints in the dates due to low-tide shore-based work. We anticipate being able to sample all 4 stations in 1 day by doing some of the filtering work while underway to each station, a scheme that worked successfully in 2010. |

ports and dates of intermediate stops
or to list additional port stops |
Because the scientific crew will be based on the Olympic Peninsula of Washington state, boarding the R/V Barnes at Neah Bay will be efficient and to immediately do the concordant shore-based sampling before and after the cruise.In 2010, we found that a pick-up at Neah Bay, WA with 10-12 h working, and a dropoff at Port Angeles, WA completed the scientific itinerary. |
